We use numerical methods to explore patterns of vertebrate endemism in south-eastern Africa, refining the boundaries of the intuitively-defined Maputaland-Pondoland-Albany biodiversity hotspot, also proposing a zoogeographic regionalisation. An incidence matrix of 300 vertebrate species endemic to south-eastern Africa sensu lato in 37 operational geographic units were used in (a) phenetic cluster analysis (PCA) using the algorithm of unweighted pair-group method with arithmetic averages (phenetic approach), and (b) parsimony analysis of endemicity (PAE; parsimony approach), in order to numerically evaluate the bioregional delimitations. The analyses provide a valid biogeographical entity 37% larger than the Maputaland-Pondoland-Albany hotspot, but substantially (131%) higher in vertebrate endemicity viz. the Greater Maputaland-Pondoland-Albany (GMPA) region of vertebrate endemism. South-east Africa is recognised as a dominion in the global zoogeographical area hierarchy, with subordinate units including the GMPA province. Various spatially-based measures of endemism were mapped for vertebrate species restricted to the dominion, i.e. endemic to south-eastern Africa sensu stricto. Areas and centres of endemism detected respectively from PAE and PCA, within the south-east Africa dominion also support the refined boundary of the GMPA region of endemism, which provides a better spatial conservation priority compared to the Maputaland-Pondoland-Albany hotspot. Reptiles and amphibians are found to be the main drivers of the overall pattern of endemism, while the pattern in freshwater fish is the most distinctive. Our analyses also indicate a good congruence of the centres of endemism across different terrestrial vertebrate taxa.

Human fascioliasis in South Africa.

PubMed

Black, J; Ntusi, N; Stead, P; Mayosi, B; Mendelson, M

2013-07-29

Human fascioliasis has the widest latitudinal, longitudinal and altitudinal distribution of any vector-borne disease, yet only 3 cases have been reported from South Africa, the last in 1964. We report 2 cases from the same geographic area associated with local consumption of watercress, suggesting an endemic focus. 

Tracking data from nine free-roaming Cheetahs (Acinonyx jubatus) collared in the Thabazimbi area, Limpopo Province, South Africa

Abstract Background In partnership with the University of Pretoria, the Endangered Wildlife Trust’s Carnivore Conservation Programme collared six male and three female free-roaming Cheetahs (Acinonyx jubatus) in the Thabazimbi area in Limpopo Province, South Africa. This study was undertaken to determine the spatial ecology of free-roaming Cheetahs that occur outside of formal protected areas on private ranchland, where they frequently come into conflict with, and are sometimes killed by, private landowners. The data were collected between September 2003 and November 2008, resulting in a total of 3165 location points (65 points from VHF collars and 3100 from GPS collars) for nine individual Cheetahs. New information This dataset provides distribution information about this Vulnerable species occurring outside of protected areas within South Africa. The dataset has been published to the Global Biodiversity Information Facility (www.GBIF.org) and provides the largest dataset on Cheetahs thus far, and, although it is spatially limited to a relatively small region on the African continent, it is the first study of its kind within South Africa. Also of significance is that the fate of 6 of the 9 collared Cheetahs is known, all except one of which died of anthropogenic causes. PMID:28325981

Africans and the myth of rural retirement in South Africa, ca 1900-1950.

PubMed

MacKinnon, Aran S

2008-06-01

The South African mining industry relied upon a massive African migrant workforce from the rural areas. Rural transformations in this migrant labor system form an important part of the story of developing capitalism in industrializing South Africa. Yet, recent historical studies on southern African migrant and rural wage labor have paid little attention to life adjustments made by the elderly and those 'burned out' by the mines and forced to leave formal wage employment in the urban areas. The South African segregationist state's rhetoric implied that 'retired' Africans could find economic security in their designated rural reserves. Indeed, legislation sought to prohibit Africans who were not employed from remaining in the 'white' urban areas. By the 1930s, however, the reserves were rapidly deteriorating. Many elderly Africans could not retire and were forced to seek wage labor. This raises significant questions about how retirement came to be defined and experienced by Africans in South Africa during a critical period of dramatic economic decline in the 1930s and 40s, and what the underlying material circumstances of African South Africans were with regard to adaptations to employment and ageing-related life changes. In many cases, elderly Africans were forced to forgo retirement, and find wage labor, usually in the most poorly paid, least sought-after or dangerous fields of employment. This article thus seeks to illuminate critical generational dimensions of the impact of segregation and racism in South Africa prior to the formal articulation of Apartheid.

Effect of wildfires on surface reflectance from a savanna ecosystem

NASA Astrophysics Data System (ADS)

Poudyal, R.; Gatebe, C. K.; Ichoku, C. M.; Varnai, T.

2015-12-01

During an airborne field campaign in South Africa in 2005, NASA's Cloud Absorption Radiometer (CAR) flew aboard South Africa Weather Service, Aerocommander 690A and measured surface bidirectional reflectance-distribution function (BRDF) over savanna comprised mostly of grasses and a few scattered trees. Savannas cover half the surface of Africa, large areas of Australia, South America, and India. . The region that was studied is located in Kruger National Park in northeastern South Africa, which was heavily affected by the wildfires. The CAR measured surface reflectance along its flight path covering both burned and unburned areas. . In this study, we compared surface reflectance between burnt and un-burnt areas at various wavelengths (340nm, 380nm, 472nm, 682nm, 870nm, 1036nm, 1219nm, 1273nm, and 2205nm) at satellite sub-pixel scales. We found a relative burnt surface reflectance decrease of between 8 and 65% due to fires. These results not only serve to highlight the importance of biomass burning and effects on the energy budgets, but also the need to determine the effects of albedo changes due to fires on soil moisture budget, evapotranspiration, infiltration, and runoff, all of which govern the land-surface component of the water cycle.

South-South medical tourism and the quest for health in Southern Africa.

PubMed

Crush, Jonathan; Chikanda, Abel

2015-01-01

Intra-regional South-South medical tourism is a vastly understudied subject despite its significance in many parts of the Global South. This paper takes issue with the conventional notion of South Africa purely as a high-end "surgeon and safari" destination for medical tourists from the Global North. It argues that South-South movement to South Africa for medical treatment is far more significant, numerically and financially, than North-South movement. The general lack of access to medical diagnosis and treatment in SADC countries has led to a growing temporary movement of people across borders to seek help at South African institutions in border towns and in the major cities. These movements are both formal (institutional) and informal (individual) in nature. In some cases, patients go to South Africa for procedures that are not offered in their own countries. In others, patients are referred by doctors and hospitals to South African facilities. But the majority of the movement is motivated by lack of access to basic healthcare at home. The high demand and large informal flow of patients from countries neighbouring South Africa has prompted the South African government to try and formalise arrangements for medical travel to its public hospitals and clinics through inter-country agreements in order to recover the cost of treating non-residents. The danger, for 'disenfranchised' medical tourists who fall outside these agreements, is that medical xenophobia in South Africa may lead to increasing exclusion and denial of treatment. Medical tourism in this region and South-South medical tourism in general are areas that require much additional research. Copyright © 2014. Published by Elsevier Ltd.

The reach of human health risks associated with metals/metalloids in water and vegetables along a contaminated river catchment: South Africa and Mozambique.

2018-05-01

Anthropogenic pollution was identified as an environmental problem of concern when, in 2008, dozens of crocodiles died in the Olifants River catchment near the border of South Africa and Mozambique. Given the close proximity of households to the river and their making use of river water, we aimed to determine to what extent water pollution has an impact on health of indigent communities in South Africa and Mozambique in the catchment area. Water and vegetable samples were collected from the study areas. Biota samples were washed with double de-ionized Milli-Q water and freeze-dried. Heavy metal analyses in water and vegetables were done by means of Inductively Coupled Plasma Optical Emission Spectroscopy. Metal concentrations were applied in a human health risk assessment to estimate health risks. Mean concentrations of antimony, arsenic, cadmium, chromium, mercury, molybdenum, nickel and selenium in water samples from South Africa exceeded the World Health Organization guidelines for safe levels of intake. Only iron exceeded the recommended guidelines in water samples from Mozambique. Metals/metalloids were found in lower concentrations at Mozambique sites downstream of South African sites. In vegetables, uranium was between 10 and 20 times above safe guidelines in South Africa and between 3 and 6 times in Mozambique. Arsenic in water samples posed the highest cancer risk. Even with a reduction in the metal concentrations in river water from South Africa to Mozambique, the potential to cause adverse human health impacts from direct use of polluted river water is evident in both countries.

Patterns of glacial-interglacial vegetation and climate variability in eastern South Africa

NASA Astrophysics Data System (ADS)

Dupont, Lydie; Caley, Thibaut; Malaizé, Bruno; Giraudeau, Jacques

2010-05-01

Vegetation is an integrated part of the earth system and our understanding needs records of its glacial-interglacial variability. Although the data coverage for South Africa is slightly better than for some other parts of Africa, there are only very few records that allow us a glimpse of the vegetation history and development through one or more late Quaternary climate cycles. The existing evidence is fragmentary and in some cases contradictory. Marine sediments can offer here continuous sequences that cover large periods of time and provide a record of a signal that integrates rather large continental regions. Core MD96-2048 has been cored off the Limpopo River mouth at 26°10'S 34°01'E in 660 m water depth. This area is under the double influence of continental discharge and Agulhas current water advection. The sedimentation is slow and continuous. The upper 5 meter (down till 250 ka) have been analysed for pollen and spores at millennial resolution. The terrestrial pollen assemblages indicate that during interglacials the vegetation of eastern South Africa and southern Mozambique largely consisted of evergreen and deciduous forests with an increase of dry deciduous forest and open woodland during interglacial optima. During glacials open mountainous shrubland extended. The pattern strongly suggests a shifting of altitudinal vegetation belts in the mountains primarily depending on temperature, although the decline of forested areas during glacial times might also be the effect of low atmospheric carbon dioxide concentrations. This pattern in eastern South Africa differs from that suggested for western South Africa, where extension of the winter rain climate seems likely, and corroborates findings of increased C4 vegetation during the Glacial of eastern South Africa. The spread of dry deciduous forest and open woodland suggests a hot and dry climate during interglacial optima. The vegetation and climate of eastern South Africa seems to follow a mid to high latitude rhythm, in which the glacial-interglacial contrast is more important than the precessional forced monsoon system of tropical Africa.

Hosegood, Victoria; McGrath, Nuala; Moultrie, Tom

2015-01-01

This paper describes marriage and partnership patterns and trends in rural KwaZulu-Natal, South Africa from 2000-2006. The study is based on longitudinal, population-based data collected by the Africa Centre demographic surveillance system. We consider whether the high rates of non-marriage among Africans in South Africa reported in the 1980s were reversed following the political transformation underway by the 1990s. Our findings show that marriage has continued to decline with a small increase in cohabitation among unmarried couples, particularly in more urbanised areas. Comparing surveillance and census data, we highlight problems with the use of the ‘living together’ marital status category in a highly mobile population. PMID:25729322

Republic of South Africa: unraveling the population puzzle. Country profile.

PubMed

Spain, D

1984-06-01

This discussion of the Republic of South Africa focuses on population growth, regions and cities, ethnicity and religion of the population, age distribution, housing and households, education, employment, income, and marketing and communication. South Africans, condemmed by the world community for their policy of racial discriminatioon, contend that outsiders fail to understand the system they legalized in 1948. Apartheid calls for developing different political institutions for blacks and whites in preparation for their eventual separation. According to this reasoning, black Africans are not considered permanent residents of South Africa, but rather of the "homelands" to which each tribal group has been assigned by the government. 4 homelands have been made independent, and if the remaining 6 become independent as scheduled, South Africa theoretically will no longer have any black citizens. Under this plan, nearly 90% of the current area of South Africa would go to whites, while the remaining 10% would be divided among the 10 homelands. The UN has condemmed the homelands policy, and no country has recognized their independence. By law South Africa has 4 distinct populations: Africans, whites, coloureds, and asians. Rhe combination of Afrikaners and British makes up the white population. Whites are in the minority and numbered only 4.7 million in 1983, or 15% of the total population. Since whites rule the country, their importance is far disproportionate to their numbers. There were 2.7 million coloureds in 1983, approximately 9% of all South Africans. Black africans, the single largest population group, numbered 22.7 million in 1983, or 73% of the total population. Blacks are divided in 10 subgroups corresponding to the 10 ethnicallyy based homelands. The largest groups are the Zulu (5.9 million in 1981) and the Xhosa (3.1 million). Population growth varies by race. The annual growth rate for the entire country was 2.4% in 1983, but for blacks it was 2.7% and for whites it was only 1.5%. The birthrate among whites in 1980 was 16.5 births/1000 whites compared with 40 births/1000 blacks. Immigration has played an important role in South Africa's white population growth. Net migration in 1981 was 33,000; 55% of new arrivals were from Europe and 40% were from other African countries. In 1980, just over half the population (53%) lived in urban areas. Approximately 90% of whites and Asians lived in urban areas, while 3/4 of coloureds and 38% of blacks were classified as urban. understanding South Africa's racial and ethnic divisions is the key to understanding the country. Political and social interaction across racial lines is forbidden. Economic relationships are strictly controlled by the passbrook system. The passbook, which must be carried by every black aged 16 and olfder, establishes a black's right to be in a particular area of the country. South Africa's population is fairly young due to a history of high fertility and high mortality among blacks, coloureds, and Asias. For the population as a whole, 38% were under age 15 in 1980 and 4% were aged 65 and older. Whites accounted for 22% and blacks 64% of the labor force in 1980. The government has tried to narrow the wage gap between white and black workers. In 1972 blacks earned only 15% of whites salaries; by 1981 black wages were 24% of white wages.

Brazil-Africa geological links

1981-04-01

In this work, the main evidence and conclusions regarding geological links between Brazil and Africa are summarized, with emphasis on the geochronological aspects. Taking into account the geographical position, as well as the similarities in the geochronological pattern, the following main provinces of the two continents are correlated: The Imataca and Falawatra complexes in the Guayana Shield and the Liberian Province of West Africa. The Paraguay-Araguaia and the Rockelide Fold Belts. The Sa˜o Luiz and the West African cratonic areas. The Caririan Fold Belt of northeastern Brazil and the Pan-Africa Belt of Nigeria and Cameroon. The JequiéComplex of Bahia, the Ntem Complex of Cameroon and similar rocks of Gabon and Angola. The Ribeira Fold Belt in Brazil and the West Congo and Damara Belts in West and South Africa. In addition, other geological links are considered, such as some of the major linear fault zones which can be traced across the margins of South America and Africa, in the pre-drift reconstructions. Correlations are also made of the tectonic and stratigraphic evolution of the Paranáand Karroo syneclises, and the Brazilian and African marginal basins around the South Atlantic, during their initial stages. Finally, several similarities in the tectonic evolution of South America and Africa, during and after the onset of drifting, are shown to be compatible with a recent origin for the South Atlantic floor, as required by sea-floor spreading and continental drift between South America and Africa.

Managing wetlands for disaster risk reduction: A case study of the eastern Free State, South Africa

PubMed Central

Collins, Nacelle

2018-01-01

This article investigated the knowledge and practice of a nature-based solution to reduce disaster risks of drought, veld fires and floods using wetlands in the eastern Free State, South Africa. A mixed research method approach was used to collect primary data using three data collection tools, namely questionnaires, interviews and field observations. Ninety-five wetlands under communal and private ownership as well as a few in protected areas were sampled, with their users completing questionnaires. The study showed that communal wetlands were more degraded, while wetlands in protected areas and in private commercial farms were in a good ecological state. An extensive literature review reveals that healthy wetlands are effective buffers in reducing disaster risks such as drought, veld fires and floods which are recurrent in the study area. Therefore, through better land-use and management practices, backed by education and awareness, wetlands could be good instruments to mitigate recurrent natural hazards in the agriculturally dominated eastern Free State in South Africa.

Learning from HIV: exploring migration and health in South Africa.

PubMed

Vearey, Joanna

2012-01-01

Southern Africa is associated with high HIV prevalence and diverse population movements, including temporary, circular movements between rural and urban areas within countries (internal migration), and movements across borders (international migration). Whilst most migration in southern Africa is associated with the search for improved livelihood opportunities in urban areas a small--but significant--number of people are forced to migrate to escape persecution or civil war. This paper utilises recent empirical studies conducted in South Africa to explore linkages between migration into urban areas and health, focusing on HIV. It is shown that the relationship between migration and HIV is complex; that both internal and international migrants move to urban areas for reasons other than healthcare seeking; and that most migratory movements into urban areas involve the positive selection of healthy individuals. Whilst healthy migration has economic benefits for rural sending households, the data uncovers an important process of return migration (internally or across borders) in times of sickness, with the burden of care placed on the rural, sending household. There is an urgent need for a comprehensive response that maintains the health of migrants in urban areas, and provides support to rural areas in times of sickness.

The distribution, relative abundance, and seasonal phenology of Ceratitis capitata, Ceratitis rosa, and Ceratitis cosyra (Diptera: Tephritidae) in South Africa.

Ceratitis capitata (Wiedemann), Ceratitis rosa Karsch, and Ceratitis cosyra (Walker) are fruit fly species (Diptera: Tephritidae) of economic importance in South Africa. These pests cause direct damage to a number of commercially produced fruit and are of phytosanitary concern. A study was conducted to determine the distribution, relative abundance, and seasonal occurrence of the three species in different climatic regions of South Africa. The relative abundance and seasonal phenology of C. capitata and C. rosa were also compared between production areas and home gardens in Stellenbosch, Western Cape. Yellow bucket traps baited with Biolure were used to trap the flies over a 2-yr period in the different sampling areas. Different fruit types were sampled in Stellenbosch to determine fruit fly infestation. C. capitata was found to have a widespread distribution in South Africa, whereas C. rosa were absent from or only present in low numbers in the drier regions. C. cosyra was restricted to the North East and East coast, following a similar pattern to the distribution of marula, Sclerocarrya birrea, an important wild host. Fruit in home gardens provided a breeding ground for C. capitata and C. rosa and a source for infestation of orchards when fruit started to mature, highlighting the need for an area-wide strategy for the control of fruit flies.

Anthelmintic resistance of nematodes in communally grazed goats in a semi-arid area of South Africa.

PubMed

Bakunzi, F R

2003-09-01

A survey was conducted on the occurrence of anthelmintic resistance of nematodes in communally grazed goats in a semi-arid area in South Africa. In herds belonging to 10 small-holder goat farmers, the efficacies of fenbendazole, levamisole and rafoxanide were tested by faecal egg count reduction (FECR) tests. Efficacies of 80% were considered a threshold for anthelmintic resistance. The FECR tests showed that all drugs tested more than 80% effective in most instances, but there were notable exceptions. In 1 case, rafoxanide was only 31% effective and in another case fenbendazole was only 47% effective. The occurrence of anthelmintic resistance in this farming sector is of concern. Steps should be taken to prevent its further spread and to avoid the development of a situation as on numerous commercial sheep farms in South Africa where resistance is very common.

African horse sickness (AHS) is a hemorrhagic viral fever of horses. It is the only equine disease for which the World Organization for Animal Health has introduced specific guidelines for member countries seeking official recognition of disease-free status. Since 1997, South Africa has maintained an AHS controlled area; however, sporadic outbreaks of AHS have occurred in this area. We compared the whole genome sequences of 39 AHS viruses (AHSVs) from field AHS cases to determine the source of 3 such outbreaks. Our analysis confirmed that individual outbreaks were caused by virulent revertants of AHSV type 1 live, attenuated vaccine (LAV) and reassortants with genome segments derived from AHSV types 1, 3, and 4 from a LAV used in South Africa. These findings show that despite effective protection of vaccinated horses, polyvalent LAV may, paradoxically, place susceptible horses at risk for AHS. PMID:27442883

Large numbers of tourists visit South Africa every year. Travelers to urban areas are at little risk of contracting an infectious disease, however the adventure traveler is at increased risk. Yellow fever is not known to occur in South Africa. Malaria is endemic in Mpumalanga and KwaZula-Natal. Schistosomiasis is endemic in large parts of the country. Although rabies is found throughout the country, only a small number of human cases is reported. High risk areas are KwaZulu-Natal, the eastern Cape and Mpumalanga provinces. The incidence of human immunodeficiency virus (HIV) infection is high and counseling regarding sexually transmitted diseases is important. Sanitation of water is excellent in most large cities and towns; however travelers to rural areas should exercise caution. Arbovirus infections do occur but relatively few cases are reported. The hiker is at risk for tick bite fever and should be counseled. Since the abolition of apartheid, South Africa has been seen as an inexpensive, high quality destination by many tourists. In 1997, a total of 5,436,848 travelers from many different countries visited the country. Areas most frequently visited include Johannesburg, Cape Town, Durban, the Garden Route, Kruger National Park, KwaZulu-Natal and Pretoria. The most common reason for visiting the country was holiday (44%), followed by visiting friends and relatives (23%), business travel (27%) other (6%).1 Travelers, to the larger cities such as Johannesburg, Cape Town and Durban are at little risk of acquiring an infectious disease. The adventure traveler however is at greater risk as parts of the country are endemic for malaria, schistosomiasis, rabies, food and waterborne diseases, sexually transmitted diseases and arbovirus infections. Accidental deaths due to motor vehicle accidents and interpersonal violence are important health risks in South Africa. Travelers visiting popular attractions are at significantly lower risk. However this has never been quantified. This review aims to address the occurrence of infectious diseases and attempts to give guidelines to practitioners caring for travelers.

The purpose of this paper is to determine whether there is a difference in the development of shopping lists and use of advertisements as pre-store food-buying practices in terms of planned shopping by South African consumers who dwell in different socio-economic status (SES) areas. The paper also considers the influence of shopper and socio-demographic characteristics on pre-store food-buying practices in a developing country. A self-administered questionnaire was used to survey 1 200 consumers in retail stores in low, middle and high SES areas in South Africa. A generalised linear model was employed for the statistical analysis of pre-store food-buying practices within the SES area groups in a developing country. South African consumers that reside in high SES area displayed the largest of shopping list development, while consumers who dwell in low SES areas showed the highest incidence of advertisement usage. Several shopper and socio-demographic characteristics were also found to have an influence on pre-store food-buying practices in different SES areas in South Africa. A qualitative approach would offer a deeper understanding of consumers' pre-store food shopping predispositions as opposed to the quantitative approach, which was adopted for this study. A longitudinal design would also provide a more extensive representation of pre-store food shopping practices over a longer time frame than cross-sectional research. The survey was conducted on Saturdays, whereas consumers who shop during the week may have different shopping and socio-demographic characteristics. Astute food brands, marketers and grocery stores could use the findings of this study to assist with their marketing efforts that they direct at consumers in different SES areas in South Africa and other developing countries. The findings of this study may assist consumers in developing countries, especially those who reside in low SES areas, with food-buying strategies to reduce food costs, make wiser purchase decisions and reduce shopping. No study (to the best of the researchers' knowledge) has considered shopping list development and use of advertisements' pre-store food-buying practices in different SES areas in a developing country. Furthermore, there is a dearth of research analysing shopper and socio-demographic characteristics in relation to pre-store food-buying practices among different SES areas in developing and developed countries.

South Africa is one of the 22 high tuberculosis burden countries that contribute 80% of the global tuberculosis cases. Tuberculosis is infectious and due to its rapid and easy transmission route poses a threat to population health. Considering the importance of social and psychological factors in influencing health outcomes, appraising knowledge and awareness of tuberculosis, remain vital for effective tuberculosis control. The main aim of this study was to investigate the factors that predict knowledge about tuberculosis among 18-64 year old adults in South Africa. A cross-sectional survey method was used. Multi-stage disproportionate, stratified cluster sampling was used to select households within enumeration areas stratified by province and locality type. Based on the Human Sciences Research Council 2007 master sample, 500 Enumerator Areas representative of the socio-demographic profile of South Africa were identified and a random sample of 20 households was randomly selected from each Enumerator Area, yielding an overall sample of 10,000 households. The tuberculosis module contained in the South African National Health And Nutrition Examination Survey I was the only module that examined the social determinants of an infectious disease. This module was questionnaire-based with no biomarkers obtained to screen for the presence of tuberculosis disease among the participants. Data was collected by administering a researcher developed individual level questionnaire. Simple and multiple linear regression was used to determine the independent variables associated with tuberculosis knowledge. Half the sample (52.6%) was female and the majority of the respondents were black African (76.5%). More than two thirds (68.0%) resided in urban areas, 56.9% did not complete high school and half were not in formal employment. Significant predictors of tuberculosis knowledge were race, sex, completion of high school, being in employment, having a diagnosis of the disease in ones' life-time and learning about tuberculosis from television, brochures, health workers, and teachers. To reduce the burden of tuberculosis in South Africa, media campaigns targeting both rural and urban communities should include conveying accurate information about the disease. Policy makers should also address structural barriers that vulnerable communities face.

This study examined the quality of family relationships and its associations with the severity of unmet needs of individuals admitted to a tertiary psychiatric hospital in South Africa. The quality of family relations and perceived unmet needs were assessed using the Lehman Quality of Life Interview and Camberwell Assessment of Needs, respectively. The results show that higher total unmet needs were associated with lower quality of family relations. The main areas of serious unmet needs included accessing government benefits and information, and establishing social relations. The results have implications for hospital-based social workers beyond managing psychiatric symptoms in South Africa. PMID:26731612

Zeitoun, O; Shemesh, N

In South Africa breast and cervical cancer are the most predominant cancers amongst women, with mortality rates reaching surprising proportions. As a result of the continued rise of these conditions it is vital to determine these women's awareness of both, so as to determine the exact factors contributing to this rise. Whilst both urban and rural areas are afflicted, this study focused primarily on women in a rural area. This was a descriptive cross-sectional study conducted in a shopping mall located in the rural area of Bushbuckridge, Mpumalanga, South Africa. A total of 300 women of reproductive age were randomly identified and requested to fill out a study questionnaire assessing their level of breast and cervical cancer awareness. A total of 300 women participated in the study. The mean age of participants was 35.66 with a range of 13.53. Overall levels of knowledge about breast and cervical cancer in rural Bushbuckridge were found to be reduced with 66.89% and 74.49% of women who rated themselves with a poor understanding of breast and cervical cancer knowledge respectively. Among the participating women, those over the age of 40, with higher level of education were found to be more cognizant in terms of breast and cervical cancer awareness with a 30% (p = 0.0923) and 52% (p < 0.001) respectively. Their younger and less educated counterparts had a 21% (p = 0.078) and 32% (p = 0.034) awareness of breast and cervical cancer, respectively. The leading source of information for both breast and cervical cancer was healthcare facilities with a 67.11% and 63.5% respectively. This study highlights the lack of awareness and knowledge of breast and cervical cancer in women living in the rural area of Bushbuckridge, South Africa. There is also evidence showing that the older and more educated women have better knowledge than their younger and less educated counterparts, therefore there is a need for increased breast and cervical cancer education and awareness campaigns amongst women in rural South Africa. The Results further point to education and availability of health care services as pivotal determinants of health.

We tested the hypothesis that adult African clawed frogs (Xenopus laevis) inhabiting water bodies in maize-growing areas (MGA) of South Africa would exhibit differences in testicular structure compared to frogs from water bodies in non-maize-growing areas (NMGA) in the same locale. Adults of both sexes were collected during the autumn of 2002 in South Africa, and stereological analytical techniques were used to quantify the distribution of testicular cell types. In addition, total laryngeal mass was used as a gauge of secondary sex differences in animals from MGA and NMGA study sites. Evaluation of the total laryngeal mass revealed that there were no statistically significant differences between X. laevis of the same sex from the NMGA and MGA sites. Mean percent fractional-volume values for seminiferous tubule distribution of testicular cell types of mature X. laevis, ranged from 3-4% for spermatogonia, 26-28% for spermatocytes, 54-57% for spermatozoa, and 14-15% for other cells types. The mean percent volume for blood vessels ranged from 0.3-0.4%. These values did not differ significantly between frogs from NMGA and MGA areas. Collectively, these data demonstrated no differences in gonadal and laryngeal development in X. laevis collected in South Africa from MGA and NMGA areas and that there is little evidence for an effect of agricultural chemicals used in maize production functioning as endocrine disrupters in this species. Screening of X. laevis testes revealed a small incidence of Stage 1 testicular oocytes in adult male frogs collected from the NMGA (3%) and MGA (2%).

There is a need for effective prevention programmes aimed at reducing risk behaviour among South African adolescents. HealthWise South Africa is a school-based programme designed to reduce sexual and substance use risk behaviour, and promote positive use of leisure time among high-school learners (students). Based on successful programmes in the United States of America, HealthWise was developed for use in South Africa and pilot tested in four South African high schools. We carried out a process evaluation to establish the fidelity of implementation and make sure HealthWise was culturally relevant. Data sources comprised focus groups with educators and learners, lesson evaluations and observations, and interviews with school principals. Qualitative analysis of data highlighted pertinent cultural and contextual factors and identified areas for modifying HealthWise in order to promote better programme-consumer fit. These areas centred on time, language, and leisure. We noted a dynamic tension between the educators' desire to adhere to plan, and to make adaptations in accordance with learners' needs and the context. Ultimately, researchers need to find a balance between fidelity of implementation and programme adaptation to obtain effective programmes that are culturally acceptable to local consumers.

In developing countries like South Africa processed geographic information systems (GIS) data on land suitability, is often not available for land use management. Data in this article is based on a published article "The strategically located land index support system for humans settlements land reform in South Africa" (Musakwa et al., 2017) [1]. This article utilities data from Musakwa et al. (2017) [1] and it goes on a step further by presenting the top 25th percentile of areas in the country that are strategically located and suited to develop spatially integrated human settlements. Furthermore the least 25th percentile of the country that are not strategically located and spatially integrated to establish human settlements are also presented. The article also presents the processed spatial datasets that where used to develop the strategically located land index as supplementary material. The data presented is meant to stir debate on spatially integrated human settlements in South Africa.

To assess the accuracy of assessment of eligibility for early medical abortion by community health workers using a simple checklist toolkit. Diagnostic accuracy study. Ethiopia, India and South Africa. Two hundred seventeen women in Ethiopia, 258 in India and 236 in South Africa were enrolled into the study. A checklist toolkit to determine eligibility for early medical abortion was validated by comparing results of clinician and community health worker assessment of eligibility using the checklist toolkit with the reference standard exam. Accuracy was over 90% and the negative likelihood ratio <0.1 at all three sites when used by clinician assessors. Positive likelihood ratios were 4.3 in Ethiopia, 5.8 in India and 6.3 in South Africa. When used by community health workers the overall accuracy of the toolkit was 92% in Ethiopia, 80% in India and 77% in South Africa negative likelihood ratios were 0.08 in Ethiopia, 0.25 in India and 0.22 in South Africa and positive likelihood ratios were 5.9 in Ethiopia and 2.0 in India and South Africa. The checklist toolkit, as used by clinicians, was excellent at ruling out participants who were not eligible, and moderately effective at ruling in participants who were eligible for medical abortion. Results were promising when used by community health workers particularly in Ethiopia where they had more prior experience with use of diagnostic aids and longer professional training. The checklist toolkit assessments resulted in some participants being wrongly assessed as eligible for medical abortion which is an area of concern. Further research is needed to streamline the components of the tool, explore optimal duration and content of training for community health workers, and test feasibility and acceptability.

In the coastal areas north-east and south-west of Knysna, South Africa lie natural forests, lakes and lagoons highly regarded by many for their aesthetic and ecological richness. A freeway construction project has given rise to fears of the degradation or destruction of these natural features. The possibility was investigated of using ERTS imagery to estimate the environmental impact of the freeway and found that: (1) All threatened features could readily be identified on the imagery. (2) It was possible within a short time to provide an area estimate of damage to indigenous forest. (3) In several important respects the imagery has advantages over maps and aerial photos for this type of work. (4) The imagery will enable monitoring of the actual environmental impact of the freeway when completed.

Gastroenterology training in private hospitals: India vs South Africa

Mulder, Chris Jacob Johan; Puri, Amarender Singh; Reddy, Duvvur Nageshwar

2010-01-01

In South Africa, nurses and doctors are emigrating in significant numbers. Job satisfaction, safety and ensuring career progression are important in retaining doctors to make a career in Republic of South Africa (RSA). Due to budgetary constraints many hospitals have not been upgraded. Coming home after overseas training seems difficult. In RSA it takes a minimum of 13 years for a young specialist to become registered and 15 years for subspecialists. Career progression, creating more specialist trainees in public and private hospitals and shortening the period of professional training are potential solutions to the problem. India, which has a population of more than 1 billion people, is struggling with similar problems. For the past 10-15 years, private hospitals have assisted in manpower development for medical specialist and subspecialist careers. Currently their private sector trains 60% of their recognised (sub)specialities fellows. A national task force for specialist training in RSA should be instituted. It should discuss, based on the current status and projected specialist and subspecialist personnel requirements, the future structure and logistics of training needs. This is required in all subspecialities including gastroenterology, as has been done in India. It is hoped that as a consequence well-trained doctors, similar to those in India, might move to provincial hospitals in rural areas, upgrading the medical services and keeping medical power in South Africa. South Africa should become a model for Sub-Saharan Africa, as India already is for South-East Asia. PMID:20180232

The aim of this study was to identify and determine the genetic diversity of Fasciola species in cattle from Zimbabwe, the KwaZulu-Natal and Mpumalanga provinces of South Africa and selected wildlife hosts from Zimbabwe. This was based on analysis of DNA sequences of the nuclear ribosomal internal transcribed spacer (ITS1 and 2) and mitochondrial cytochrome oxidase 1 (CO1) regions. The sample of 120 flukes was collected from livers of 57 cattle at 4 abattoirs in Zimbabwe and 47 cattle at 6 abattoirs in South Africa; it also included three alcohol-preserved duiker, antelope and eland samples from Zimbabwe. Aligned sequences (ITS 506 base pairs and CO1 381 base pairs) were analyzed by neighbour-joining, maximum parsimony and Bayesian inference methods. Phylogenetic trees revealed the presence of Fasciola gigantica in cattle from Zimbabwe and F. gigantica and Fasciola hepatica in the samples from South Africa. F. hepatica was more prevalent (64%) in South Africa than F. gigantica. In Zimbabwe, F. gigantica was present in 99% of the samples; F. hepatica was found in only one cattle sample, an antelope (Hippotragus niger) and a duiker (Sylvicapra grimmia). This is the first molecular confirmation of the identity Fasciola species in Zimbabwe and South Africa. Knowledge on the identity and distribution of these liver flukes at molecular level will allow disease surveillance and control in the studied areas. Copyright © 2015 Elsevier B.V.

Commercial sex work or ukuphanda? Sex-for-money exchange in Soweto and Hammanskraal area, South Africa.

Wojcicki, Janet Maia

2002-09-01

This article introduces the concept of ukuphanda, a Zulu verb that is used to describe the sex-for-money exchanges that take place outside of commercial sex work in Soweto and Hammanskraal area, South Africa. In line with the ethnographic literature from others areas of sub-Saharan Africa, it is argued that women who exchange sex for money in taverns do not self-identify as commercial sex workers and experience less stigma from the community. Unlike commercial sex work (as characterized by the commercial sex work in Hillbrow, Johannesburg), which is understood to be associated with short skirts and other revealing attire, sex-for-money exchange in the taverns is viewed as more private, ambiguous and informal. Women who work as informal sex workers, or "-phandela imali" ('try to get money'), are understood to be using sex-for-money exchange to survive financially.

An investigation of MAGSAT and complementary data emphasizing precambrian shields and adjacent areas of West Africa and South America

The problems associated with the use of an interactive magnetic modeling program are reported and a publication summarizing the MAGSAT anomaly results for Africa and the possible tectonic associations of these anomalies is provided. An overview of the MAGSAT scalar anomaly map for Africa suggested a correlation of MAGSAT anomalies with major crustal blocks of uplift or depression and different degrees of regional metamorphism. The strongest MAGSAT anomalies in Africa are closely correlated spatially with major tectonic features. Results indicate that the Bangui anomaly may be caused by a central old Precambrian shield, flanked to the north and south by two relatively young sedimentary basins.

Reframing Vulnerability: Mozambican Refugees’ Access to State-Funded Pensions in Rural South Africa

PubMed Central

2012-01-01

Researchers at the South African Medical Research Council/University of the Witwatersrand Rural Public Health and Health Transitions Research Unit (Agincourt) fieldsite in rural South Africa consider Mozambican residents more vulnerable than others in the local population. These self-settled refugees, many of whom are still not South African citizens, primarily came to South Africa in the 1980s during the Mozambican Civil War. This perceived economic vulnerability is rooted in their difficulties in accessing social grants, until recently legally available only to those with South African citizenship documentation. This paper focuses on semi-structured interviews with 30 ‘older’ women of Mozambican-descent living in the Agincourt area. These interviews highlight three important aspects of vulnerability; the respondents: (1) perceive a risk of deportation despite their having lived in the country for 20 years, (2) are unable to easily access social grants, namely the state-funded old-age pension, and (3) struggle to make ends meet when faced with daily needs and crisis situations. All three of these vulnerabilities were mediated to some extent by these women’s resourcefulness. They generated ties to South Africa through obtaining identification-documents, used these documents to access pensions, and used the pensions to help them sustain their multigenerational households.

Applications of the IRI in Southern Africa

NASA Astrophysics Data System (ADS)

Coetzee, P. J.

2004-01-01

The IRI forms the basis of the Single Site Location Direction Finding networks of the South African Defence Force as well as theNational Intelligence Agency. It is also used in "Path Analysis" applications where the possible transmitter coverage is calculated. Another application of the IRI is in HF frequency predictions, especially for the South African Defence Force involved in peace keeping duties in Africa. The IRI is either used independently or in conjunction with vertical ionosondes. In the latter case the scaled F2 peak parameters (foF2, hmF2) are used as inputs to the IRI. The IRI thus gets "calibrated" to extend the area covered by the ionosonde(s). The IRI has proved to be a very important tool in South Africa and Africa in the fight against crime, drug trafficking, political instability and maintaining the peace in potentially unstable countries.

The herbicide atrazine has been suggested to cause gonadal deformities in frogs and could possibly impact on reproduction. Since the early 1960s, atrazine has been used in large amounts in maize production areas of South Africa. These areas overlap with populations of the African Clawed Frog (Xenopus laevis) that has a wide distribution in southern Africa and is found in most water-bodies including those where atrazine residues are detected. The aim of this study was to compare various attributes of individual- and population-level responses of X. laevis from maize-growing and non-maize-growing areas. Xenopus laevis were studied in three reference and five maize-growing sites. Sex ratio, snout-vent length, body-mass and age profiles were found to be similar for populations in maize-growing and non-maize-growing areas. Our mark-recapture data indicated that all sites had robust populations. There were no significant relationships between exposure to atrazine and any of the parameters investigated in populations of X. laevis.

The shift in emphasis to universal primary health care in post-apartheid South Africa has been accompanied by a process of decentralization of mental health services to district level, as set out in the new Mental Health Care Act, no. 17, of 2002 and the 1997 White Paper on the Transformation of the Health System. This study sought to assess progress in South Africa with respect to deinstitutionalization and the integration of mental health into primary health care, with a view to understanding the resource implications of these processes at district level. A situational analysis in one district site, typical of rural areas in South Africa, was conducted, based on qualitative interviews with key stakeholders and the World Health Organization's Assessment Instrument for Mental Health Systems (WHO-AIMS). The findings suggest that the decentralization process remains largely limited to emergency management of psychiatric patients and ongoing psychopharmacological care of patients with stabilized chronic conditions. We suggest that, in a similar vein to other low- to middle-income countries, deinstitutionalization and comprehensive integrated mental health care in South Africa is hampered by a lack of resources for mental health care within the primary health care resource package, as well as the inefficient use of existing mental health resources.

Quantitative Study of Vulnerability / Damage Curves in South Africa

Southern Africa is considered a stable continental region in spite of several cases of reported earthquakes, which caused considerable damage and casualties particularly in the mining industry. Most buildings and structures in South Africa are not designed to resist any intensity of earthquake and most architects, engineers and builders in the country do not consider seismic resistance as a design requirement. This is mainly because the region has not experienced any large and serious destructive earthquake in recent years. The most destructive earthquake recorded in South Africa is the Ceres earthquake of 1969. The earthquake with a magnitude of 6.3 occurred on September 29, 1969 in the Ceres-Tulbagh region of the Western Cape Province about 100 km northeast of Cape Town. Serious damage occurred to certain buildings in the area (amounting to a total of U.S. 24 million). The structural damage varied from almost total destruction of old and poorly constructed buildings to large cracks in the better-built ones, twelve people were killed and many more were injured. Another event that caused severe damage to infrastructure occurred on March 9, 2005 at Stilfontein near Klerksdorp. It is known that up to 40 or more tremors are recorded monthly in Southern Africa, the locations are predominantly in the places surrounding the gold mining areas with many events around the Carletonville and Klerksdorp areas. Recent years have seen at least four mining induced tremors causing significant damage (Welkom 1976, Klerksdorp 1977, Welkom 1989 and Carletonville 1992). Such events show that it is very necessary to take seismic events into account in the design of any infrastructure. Assessing and understanding the risk facing the South African cities as a result of major seismic activity has been paid little attention. The main focus of this study is to use results of a deterministic hazard assessment to develop the most suitable damage curves for twelve of the most common building classes in four of the major cities in South Africa, namely, Johannesburg, Cape Town, Durban and Port Elizabeth.

Russian wheat aphid Diuraphis noxia (Kurdjumov) has spread from its native area in central Asia to all the major wheat-producing countries in the world to become an international wheat pest. Because the Russian wheat aphid is a serious threat to the wheat industry in South Africa, it is important to investigate the key factors involved in the distribution of Russian wheat aphid biotypes and in the changes of the Russian wheat aphid biotype complex in South Africa. There are currently four known Russian wheat aphid biotypes occurring in South Africa. Russian wheat aphid samples were collected from 2011 to 2014 during the wheat-growing season in spring and summer and these samples were screened to determine the biotype status. RWASA1 occurred predominantly in the Western Cape, while RWASA2 and RWASA3 occurred predominantly in the Eastern Free State. Following the first record of RWASA4 in 2011, this biotype was restricted to the Eastern Free State. The surveys suggest that the Russian wheat aphid bioype complex was more diverse in the Eastern Free State than in the other wheat production areas. There was also a shift in Russian wheat aphid biotype composition over time. The Russian wheat aphid biotype complex is dynamic, influenced by environmental factors such as host plants, altitude, and climate, and it can change and diversify over time causing fluctuation in populations over sites and years. This dynamic nature of the Russian wheat aphid will continue to challenge the development of Russian wheat aphid-resistant wheat cultivars in South Africa, and the continued monitoring of the biotypic and genetic structure, to determine genetic relatedness and variation in different biotypes, of Russian wheat aphid populations is important for protecting wheat.

Nations in the 21st century face a complex mix of environmental and social challenges, as highlighted by the on-going Sustainable Development Goals process. The “planetary boundaries” concept [Rockström J, et al. (2009) Nature 461(7263):472–475], and its extension through the addition of social well-being indicators to create a framework for “safe and just” inclusive sustainable development [Raworth K (2012) Nature Climate Change 2(4):225–226], have received considerable attention in science and policy circles. As the chief aim of this framework is to influence public policy, and this happens largely at the national level, we assess whether it can be used at the national scale, using South Africa as a test case. We developed a decision-based methodology for downscaling the framework and created a national “barometer” for South Africa, combining 20 indicators and boundaries for environmental stress and social deprivation. We find that it is possible to maintain the original design and concept of the framework while making it meaningful in the national context, raising new questions and identifying priority areas for action. Our results show that South Africa has exceeded its environmental boundaries for biodiversity loss, marine harvesting, freshwater use, and climate change, and social deprivation is most severe in the areas of safety, income, and employment. Trends since 1994 show improvement in nearly all social indicators, but progression toward or over boundaries for most environmental indicators. The barometer shows that achieving inclusive sustainable development in South Africa requires national and global action on multiple fronts, and careful consideration of the interplay between different environmental domains and development strategies.

Global research suggests that persons with disabilities face barriers when accessing health care services. Yet, information regarding the nature of these barriers, especially in low-income and middle-income countries is sparse. Rural contexts in these countries may present greater barriers than urban contexts, but little is known about access issues in such contexts. There is a paucity of research in South Africa looking at "triple vulnerability" - poverty, disability and rurality. This study explored issues of access to health care for persons with disabilities in an impoverished rural area in South Africa. The study includes a quantitative survey with interviews with 773 participants in 527 households. Comparisons in terms of access to health care between persons with disabilities and persons with no disabilities were explored. The approach to data analysis included quantitative data analysis using descriptive and inferential statistics. Frequency and cross tabulation, comparing and contrasting the frequency of different phenomena between persons with disabilities and persons with no disabilities, were used. Chi-square tests and Analysis of Variance tests were then incorporated into the analysis. Persons with disabilities have a higher rate of unmet health needs as compared to non-disabled. In rural Madwaleni in South Africa, persons with disabilities faced significantly more barriers to accessing health care compared to persons without disabilities. Barriers increased with disability severity and was reduced with increasing level of education, living in a household without disabled members and with age. This study has shown that access to health care in a rural area in South Africa for persons with disabilities is more of an issue than for persons without disabilities in that they face more barriers. Implications are that we need to look beyond the medical issues of disability and address social and inclusion issues as well.

Internet and cell phones can be considered as new media compared to traditional media types and have become a fundamental part of the lives of many young people across the globe. The exploratory research study investigated the diffusion and adoption of new media innovations among adolescents. It was found that new media have diffused at a high rate among South African adolescents who are not only the innovators in this area, but also changing their life styles to adapt to the new media. Social networking grew to prominence in South Africa especially among the youth. The protection of children from potential harmful exposure and other risks remain a concern and adequate measures need to be initiated and implemented for children to enjoy social networks and other forms of new media. The exploratory research study provided worthwhile and interesting insights into the role of the new media, in the lives of adolescents in South Africa.

After the mega-earthquakes and concomitant devastating tsunamis in Sumatra (2004) and Japan (2011), we launched an investigation into the potential risk of tsunami hazard to the coastal cities of South Africa. This paper presents the analysis of the seismic hazard of seismogenic sources that could potentially generate tsunamis, as well as the analysis of the tsunami hazard to coastal areas of South Africa. The subduction zones of Makran, South Sandwich Island, Sumatra, and the Andaman Islands were identified as possible sources of mega-earthquakes and tsunamis that could affect the African coast. Numerical tsunami simulations were used to investigate the realistic and worst-case scenarios that could be generated by these subduction zones. The simulated tsunami amplitudes and run-up heights calculated for the coastal cities of Cape Town, Durban, and Port Elizabeth are relatively small and therefore pose no real risk to the South African coast. However, only distant tsunamigenic sources were considered and the results should therefore be viewed as preliminary.

This true-color image of South Africa was acquired on May 14, 2000, by NASA's Moderate-resolution Imaging Spectroradiometer, or MODIS. The image was produced using a combination of the sensor's 250-m and 500-m resolution visible wavelength bands. As part of the opening ceremony to begin the joint U.S.-South Africa SAFARI Field Experiment, NASA presented print copies of this image as GIFts to Dr. Ben Ngubane, Minister of Arts, Science and Technology, and Honorable Advocate Ngoaka Ramathlodi, Premier of the Northern Province, South Africa. The area shown in this image encompasses seven capital cities and a number of the region's distinctive geological features can be seen clearly. Toward the northern (top) central part of the image, the browns and tans comprise the Kalahari Desert of southern Botswana. The Tropic of Capricorn runs right through the heart of the Kalahari and the Botswanan capital city of Gaborone sits on the Limpopo River, southeast of the Kalahari. Along the western coastline of the continent is the country of Namibia, where the Namib Desert is framed against the sea by the Kaokoveld Mountains. The Namibian capital of Windhoek is obscured by clouds. Looking closely in the center of the image, the Orange River can be seen running from east to west, demarcating the boundary between Namibia and South Africa. On the southwestern corner of the continent is the hook-like Cape of Good Hope peninsula and Cape Town, the parliamentary capital of South Africa. Running west to east away from Cape Town are the Great Karroo Mountains. The shadow in this image conveys a sense of the very steep grade of the cliffs along the southern coast of South Africa. Port Elizabeth sits on the southeasternmost point of South Africa, and a large phytoplankton bloom can be seen in the water about 100 miles east of there. Moving northward along the east coast, the Drakensberg Mountains are visible. The two small nations of Lesotho and Swaziland are in this region, completely contained within South Africa's boundaries. In the upper righthand corner of the image is the Bay of Maputo, where sits Maputo, the capital of Mozambique. Fires are visible in the northeast corner of the image, near Maputo. Just north of Maputo is where the Limpopo River empties into the Indian Ocean. Tracing the Limpopo inland back toward the west, this river defines the northern boundary of South Africa with both Zimbabwe and Botswana. Johannesburg, the commercial capital of South Africa, can be seen as the greyish pixels in the northeastern region of the country. The country's legislative capital, Pretoria, is about 50 miles north of Johannesburg and 250 miles west of Maputo, in the heart of the Northern Province (formerly known as Transvaal).

To estimate the burden of disease attributable to lead exposure in South Africa in 2000. World Health Organization comparative risk assessment (CRA) methodology was followed. Recent community studies were used to derive mean blood lead concentrations in adults and children in urban and rural areas. Population-attributable fractions were calculated and applied to revised burden of disease estimates for the relevant disease categories for South Africa in the year 2000. Monte Carlo simulation-modelling techniques were used for the uncertainty analysis. South Africa. Children under 5 and adults 30 years and older. Cardiovascular mortality and disability-adjusted life years (DALYs) in adults 30 years and older and mild mental disability DALYs in children under 5 years. Lead exposure was estimated to cause 1,428 deaths (95% uncertainty interval 1,086-1,772) or 0.27% (95% uncertainty interval: 0.21 - 0.34%) of all deaths in South Africa in 2000. Burden of disease attributed to lead exposure was dominated by mild mental disability in young children, accounting for 75% of the total 58,939 (95% uncertainty interval 55,413 - 62,500) attributable DALYs. Cardiovascular disease in adults accounted for the remainder of the burden. Even with the phasing out of leaded petrol, exposure to lead from its ongoing addition to paint, para-occupational exposure and its use in backyard 'cottage industries' will continue to be an important public health hazard in South Africa for decades. Young children, especially those from disadvantaged communities, remain particularly vulnerable to lead exposure and poisoning.

The changing role of veterinarians in the global market is a current topic of debate and discussion. Few countries including South Africa have formally examined the changing dynamics of this profession. Therefore, the present study addressed 2 objectives. The 1st was to examine basic information about veterinarians in South Africa including their age, gender and distribution across provinces, the percentage whose practice was urban, rural or periurban, the numbers working with specific animal species, and the extent of business management and skills previously gained. The 2nd objective was to obtain opinions and insights from veterinarians in South Africa about the challenges and opportunities facing their business practices to better understand what they considered important dynamics to their businesses today. Several areas of business on which they were questioned and which were included in this study were: marketing, vision, human resources, leadership, financial management, ethics, competition, day-to-day operations, interpersonal skills and information management. This is the 1st known survey to employ a questionnaire to gain insights and opinions from veterinarians about business management skills.

Globalisation and local power: influences on health matters in South Africa.

PubMed

Gilbert, Tal; Gilbert, Leah

2004-03-01

This paper reviews some of the multiple influences on health issues in South Africa, placing them in the context of globalisation. By examining the complexity of factors, both domestic and global, which impact on these issues, it questions the extent to which global patterns in areas such as health policy, HIV/AIDS, health care pluralism, and neo-liberal macroeconomic policy have played out in South Africa. The identification of some of the multiple and complex forces in each case reveals a relatively consistent story of global pressures interacting with domestic realities, with some recognizably local results. There is no doubt that a full and nuanced understanding of health in South Africa requires an appreciation of developments in the global political economy, international organizations such as the WHO and World Bank, and forces which operate outside of institutions. In each case, however, the specific opportunities available to actors within the country, as well as the relative power of those actors, should be given their due consideration in analysing their potential impact on health matters.

Northeast African genomic variation shaped by the continuity of indigenous groups and Eurasian migrations

Hollfelder, Nina; Babiker, Hiba

2017-01-01

Northeast Africa has a long history of human habitation, with fossil-finds from the earliest anatomically modern humans, and housing ancient civilizations. The region is also the gate-way out of Africa, as well as a portal for migration into Africa from Eurasia via the Middle East and the Arabian Peninsula. We investigate the population history of northeast Africa by genotyping ~3.9 million SNPs in 221 individuals from 18 populations sampled in Sudan and South Sudan and combine this data with published genome-wide data from surrounding areas. We find a strong genetic divide between the populations from the northeastern parts of the region (Nubians, central Arab populations, and the Beja) and populations towards the west and south (Nilotes, Darfur and Kordofan populations). This differentiation is mainly caused by a large Eurasian ancestry component of the northeast populations likely driven by migration of Middle Eastern groups followed by admixture that affected the local populations in a north-to-south succession of events. Genetic evidence points to an early admixture event in the Nubians, concurrent with historical contact between North Sudanese and Arab groups. We estimate the admixture in current-day Sudanese Arab populations to about 700 years ago, coinciding with the fall of Dongola in 1315/1316 AD, a wave of admixture that reached the Darfurian/Kordofanian populations some 400–200 years ago. In contrast to the northeastern populations, the current-day Nilotic populations from the south of the region display little or no admixture from Eurasian groups indicating long-term isolation and population continuity in these areas of northeast Africa.

Reconstruction of the Palaeo-environment of the Alluvial Deposits in the Eastern Free State, South Africa

NASA Astrophysics Data System (ADS)

Evans, M. Y.

2009-04-01

Small alluvial fan systems have formed off the hillslopes of the remnant Karoo koppies at Heelbo in the Eastern Free State, South Africa. The landform geometry is a result of complex relationships between climate, lithology, structure and vegetation. This research area, which includes a large mammal mass death site, potentially contains a wealth of palaeo-environmental and specifically palaeoclimatic information. Palaeo-environmental information and proxy records on past climates in southern Africa has traditionally been obtained from a variety of techniques including stable isotope analysis of speleothems, pollen , faunal analyses at archeological sites, animal remains and crater-lake sediments (see references below). However, little information exists in the scientific literature on the use of palaeosols for defining the depositional palaeoenvironments in southern Africa. The aim of this research is to attempt to address the lack of palaeo-environmental information by extracting palaeoclimatic information from the sedimentary processes and the palaeosols at the Heelbo farm that have been extensively exposed through gullying. The sedimentary fans in the area have experienced climatically controlled histories of erosion, sedimentation and pedogenesis. Extreme sedimentation is assumed to have occurred during relatively arid climatic intervals, when decreased vegetation cover provided little surface protection. In contrast pedogenesis occurs during humid intervals when vegetation cover is restored, the land stabilizes and the uppermost gravely sands weather to form soils. A combined approach of both radiocarbon- and luminescence -dating may provide a detailed chronology of these successive hillslope events in order to relate hillslope instability to climatic forcing factors. Preliminary results indicate that at least 3 depositional events are recorded within the large mammal mass death site, which have been confirmed by the radiocarbon dates of 3,610 ±110 in the top section and 4,610 ±30 at the bottom section.

Lithostratigraphy and depositional environments in the Waterberg-Erongo area, central Namibia, and correlation with the main Karoo Basin, South Africa

NASA Astrophysics Data System (ADS)

Holzförster, Frank; Stollhofen, Harald; Stanistreet, Ian G.

The dissected landscape of the Waterberg-Erongo area, central Namibia, exposes Karoo-equivalent strata deposited in basins that occur throughout sub-Saharan Africa. Although many are of economic interest, including coal-bearing strata, their depositional history is not well understood. This study of the Waterberg-Erongo area provides detailed lithostratigraphical data, which suggest sedimentation from the late Early Triassic to the Early Jurassic in a fault-bounded depository. Subsidence and sediment supply were controlled predominantly by the northeast-southwest trending Waterberg-Omaruru Fault Zone, which defines the northwestern margin of the depository. Facies development and thickness distribution of the Karoo strata in the Waterberg-Erongo area, perhaps the most continuous of any of the Karoo basins, indicate a northeastwardly-migrating depocentre alongside that fault, in response to major extensional movements in the early pre-South Atlantic rift zone. Periodic fault movements repeatedly caused basinward progradation of the alluvial facies, which are reflected by stacked fining-upward cycles in the lithological record. On a broader scale, the results of this study suggest that the northward propagation of the rift zone between Southern Africa and South America, was partially accommodated by transfer lineaments. Local depocentres developed along these lineaments, such as those in the Waterberg-Erongo area, with localised enhanced subsidence greater than that revealed in other Namibian onshore exposures, dominated by the rifting itself.

Towards zero waste in emerging countries - a South African experience.

Matete, Ntlibi; Trois, Cristina

2008-01-01

The aim of this paper is to describe the optimisation of Waste Minimisation/Zero Waste strategies into an already established integrated waste management system and to present a Zero Waste model for post-consumer waste for urban communities in South Africa. The research was undertaken towards the fulfilment of the goals of the Polokwane Declaration on Waste Management [DEAT, 2001. Department of Environmental Affairs and Tourism, Government of South Africa. Polokwane Declaration. Drafted by Government, Civil Society and the Business Community. National Waste Summit, Polokwane, 26-28 September 2001], which has set as its target the reduction of waste generation and disposal by 50% and 25%, respectively, by 2012 and the development of a plan for Zero Waste by 2022. Two communities, adjacent to the Mariannhill Landfill site in Durban, were selected as a case study for a comparative analysis of formal and informal settlements. Since the waste generated from these two communities is disposed of at the Mariannhill landfill, the impact of Zero Waste on landfill volumes could be readily assessed. A Zero Waste scheme, based on costs and landfill airspace savings, was proposed for the area. The case study demonstrates that waste minimisation schemes can be introduced into urban areas, in emerging countries, with differing levels of service and that Zero Waste models are appropriate to urban areas in South Africa.

The integration of community health workers (CHWs) into primary and secondary prevention functions in health programs and services delivery in Mexico and South Africa has been demonstrated to be effective. Task-sharing related to adherence and treatment, from nurses to CHWs, has also been effectively demonstrated in these areas. HIV/AIDS and TB programs in South Africa have seen similar successes in task-sharing with CHWs in the areas of screening for risk and adherence to treatment. In the area of non-communicable diseases (NCDs), there is a policy commitment to integrating CHWs into primary health care programs at public health facilities in both Mexico and South Africa in the areas of reproductive health and infant health. Yet current programs utilizing CHWs are not integrated into existing primary health care services in a comprehensive manner for primary and secondary prevention of NCDs. In a recently completed study, CHWs were trained to perform the basic diagnostic function of primary screening to assess the risk of suffering a CVD-related event in the community using a non-laboratory risk assessment tool and referring persons at moderate to high risk to local government clinics, for further assessment and management by a nurse or physician. In this paper we compare the experience with this CVD screening study to successful programs in vaccination, reproductive health, HIV/AIDS, and TB specifically to identify the barriers we identified as limitations to replicating these programs in the area of CVD diagnosis and management. We review barriers impacting the effective translation of policy into practice, including scale up issues; training and certification issues; integrating CHW to existing primary care teams and health system; funding and resource gaps. Finally, we suggest policy recommendations to replicate the demonstrated success of programs utilizing task-sharing with CHWs in infectious diseases and reproductive health, to integrated programs in NCD.

Towards measuring the transaction costs of co-management in Mkambati Nature Reserve, Eastern Cape, South Africa.

During the last three decades, there has been an increased pursuit of participatory approaches to managing natural resources. In South Africa, this has been evident in the management of protected areas. In particular, land claims, which affect much of the conservation estate in South Africa, frequently result in co-management of protected areas by claimant communities and conservation agencies. This is occurring against a backdrop of declining state subsidies and growing expectations that South African conservation agencies will finance themselves while simultaneously stimulating local economic opportunities. In this context, it is important for co-management partners to understand and monitor the cost-effectiveness of management processes in achieving both the socio-economic and ecological targets of conservation management. Transaction costs are useful in gauging the cost-effectiveness of policies and institutions; however there is little methodological guidance for measuring transaction costs empirically. This study develops and tests a transaction costs model for a co-managed nature reserve in the Eastern Cape province of South Africa. Transaction costs were quantified by taking into account the total time spent in meetings annually, the daily opportunity cost of participants' time and the travel costs associated with attending such meetings. A key limitation in the development of this model was a lack of record keeping by the conservation agency. The model developed in this study offers a practical means for co-management partners in similar contexts to monitor how transaction costs change over time. Copyright © 2013 Elsevier Ltd.

Rates of obesity and overweight among South Africans are increasing. Food marketing has a profound impact on children and affects their lifelong eating patterns; in urban areas of South Africa, disposable incomes are growing and ultra-processed food is increasingly available at low cost. The combination of these factors will strain an already fragile health system. Our aim was to investigate the density of outdoor sugar sweetened beverage (SSB) advertising and the number of formal and informal vendors selling SSBs in a transforming, historically disadvantaged urban setting of South Africa. A digital camera and global positioning system navigation system were used to record the location of SSB advertisements and food vendors in a demarcated area in Soweto. Data were collected by walking or driving through each street; a food inventory was completed for every food vendor. Spatial analyses were conducted using a geographic information system. A total of 145 advertisements for SSBs were found over a driven or walked distance of 111.9 km. The density of advertisements was 3.6 per km(2) in relation to schools, and 50% of schools had branded advertising of SSBs on their school property. Most (n = 104; 58%) of the 180 vendors in the study sold SSBs. This is the first study in South Africa to document the location of billboard advertisements and vendors in relation to schools. Marketing of products that contribute to obesity is common in urban Soweto. Our findings have implications for policies that regulate SSB advertising, especially in the proximity of schools.

The burden of antenatal heart disease in South Africa: a systematic review

PubMed Central

2012-01-01

Background Maternal mortality in South Africa is rising, and heart conditions currently account for 41 per cent of indirect causes of deaths. Little is known about the burden of heart disease in pregnant South Africans. Methods We systematically reviewed the contemporary epidemiology and peripartum outcomes of heart disease in South African women attending antenatal care. Searches were performed in PubMed, ISI Web of Science, the EBSCO Africa-Wide database, the South African Union Catalogue, and the Current and Completed Research database (South Africa). References of included articles were also hand-searched. Studies reporting epidemiologic data on antenatal heart disease in South Africa were included. Data on morbidity and mortality were also collected. Results Seven studies were included in the systematic review. The prevalence of heart disease ranged from 123 to 943 per 100,000 deliveries, with a median prevalence of 616 per 100,000. Rheumatic valvular lesions were the commonest abnormalities, although cardiomyopathies were disproportionately high in comparison with other developing countries. Peripartum case-fatality rates were as high as 9.5 per cent in areas with limited access to care. The most frequent complications were pulmonary oedema, thromboembolism, and major bleeding with warfarin use. Perinatal mortality ranged from 8.9 to 23.8 per cent, whilst mitral lesions were associated with low birth weight. Meta-analysis could not be performed due to clinical and statistical heterogeneity of the included studies. Conclusion Approximately 0.6 per cent of pregnant South Africans have pre-existing cardiac abnormalities, with rheumatic lesions being the commonest. Maternal and perinatal morbidity and mortality continue to be very high. We conclude this review by summarising limitations of the current literature and recommending standard reporting criteria for future reports. PMID:22463484

Fetal alcohol spectrum disorder in Africa.

Adnams, Colleen M

2017-03-01

This review aims to summarize data published in the scientific literature and available on official websites on fetal alcohol spectrum disorder (FASD) in Africa. There is a paucity of published literature and evidence-based information on prenatal exposure to alcohol in the African continent and the majority of the continent's literature on FASD emanates from South Africa. A small number of scientific publications document FASD and drinking in pregnancy in other Sub-Saharan African countries and these findings provide evidence that FASD occurs across the continent. Further evidence shows that the world's highest reported rates of FASD occur in South Africa and that this confers a significant public health and neurodevelopmental disability burden on the region. There is an established body of epidemiological, diagnostic, neurobehavioral and neuroscientific knowledge from studies in South Africa. Universal and indicated case method preventions are effective in reducing maternal alcohol consumption in high-risk areas. Throughout Africa, a policy and service implementation gap exists that impedes translation of generated knowledge into effective prevention and intervention strategies. FASD is likely a widely occurring and largely unrecognized neurodevelopmental disability in Africa. A key future direction for global agencies and research partnerships is to collaboratively address evidence gaps and knowledge translation through scalable approaches and strategies that aim to ameliorate the burden of FASD in African and other countries.

2016-01-01

Newborn mortality, comprising a third of all under-5 deaths, has hardly changed in low and middle income countries (LMICs) including South Africa over the past decade. To attain the MDG 4 target, greater emphasis must be placed on wide-scale implementation of proven, cost-effective interventions. This paper reviews economic evidence on effective neonatal health interventions in LMICs from 2000-2013; documents lessons for South African policy on neonatal health; and identifies gaps and areas for future research. A narrative review was performed in leading public health databases for full economic evaluations conducted between 2000 and 2013. Data extraction from the articles included in the review was guided by the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist, and the quality of the included economic evaluations was assessed using the Quality of Health Economics Studies Instrument (QHES). Twenty-seven economic evaluations were identified, from South East Asia and sub-Saharan Africa, with those from sub-Saharan Africa primarily focused on HIV/AIDS. Packages of care to prevent neonatal mortality were more cost-effective than vertical interventions. A wide variability in methodological approaches challenges the comparability of study results between countries. In South Africa, there is limited cost-effectiveness evidence for the interventions proposed by the National Perinatal Morbidity and Mortality Committee. Neonatal strategies have a strong health system focus but this review suggests that strengthening community care could be an additional component for averting neonatal deaths. While some evidence exists, having a more complete understanding of how to most effectively deploy scarce resources for neonatal health in South Africa in the post-2015 era is essential.

There are few data on heart failure (HF) patients from Africa, Asia, the Middle East and South America. INTER-CHF is a prospective study that enrolled HF patients in 108 centers in 16 countries from 2012 to 2014. Consecutive ambulatory or hospitalized adult patients with HF were enrolled. Baseline data were recorded on sociodemographics, clinical characteristics, HF etiology and treatments. Age- and sex-adjusted results are reported. We recruited 5813 HF patients: mean(SE) age=59(0.2)years, 39% female, 65% outpatients, 31% from rural areas, 26% with HF with preserved ejection fraction, with 1294 from Africa, 2661 from Asia, 1000 from the Middle-East, and 858 from South America. Participants from Africa-closely followed by Asians-were younger, had lower literacy levels, and were less likely to have health or medication insurance or be on beta-blockers compared with participants from other regions, but were most likely to be in NYHA class IV. Participants from South America were older, had higher insurance and literacy levels, and, along with Middle Eastern participants, were more likely to be on beta-blockers, but had the lowest proportion in NYHA IV. Ischemic heart disease was the most common HF etiology in all regions except Africa where hypertensive heart disease was most common. INTER-CHF describes significant regional variability in socioeconomic and clinical factors, etiologies and treatments in HF patients from Africa, Asia, the Middle East and South America. Opportunities exist for improvement in health/medication insurance rates and proportions of patients on beta blockers, particularly in Africa and Asia. Copyright © 2015 Elsevier Ireland Ltd.

Urbanisation and women's health in South Africa.

Pick, W; Cooper, D

1997-03-01

For many decades the migrant labor system and the influx control legislation in South Africa exacerbated male-dominant patterns of migration typical of Africa. In recent years, however, and especially following the easing of influx control legislation in 1986, migration in South Africa has increasingly involved women. This paper reports on a study conducted in Khayelitsha, Cape Town, which explored the relationship between urbanisation and the health of women. The objectives were to relate age, migration, length of stay in urban areas, employment status, and occupation to the health, including reproductive health, of women living in Khayelitsha. Interviews with 659 women (61 households had no senior woman) revealed that women enjoyed considerable social support through their neighbours, church organisations, and women's organisations. Women who lived in the most deprived section of Khayelitsha enjoyed more support from their neighbours but reported less satisfaction with the area in which they lived. Child-care support was poor and a considerable proportion of the women were disempowered by their male partners. More than 90 percent of the women had access to antenatal care. Recent immigrants had more pregnancies, were less aware of screening for cervical cancer, less likely to have had a Pap smear, less knowledgeable about where to have a Pap smear done, and less likely to have heard AIDS. More women were aware of AIDS (86%) than Pap smears (45%). More than half of those of childbearing age used contraception, mainly intramuscular hormones (76%). A significant proportion (53%) of the women reported that they had had their first pregnancy as teenagers and younger, less educated women were more likely to have had adolescent pregnancies. Policy makers are confronted by a compelling need to redress well-known urban-rural inequalities in health care in South Africa. Policy attention must also be given to the increasing urbanisation of women and the growing health care needs in urban areas.

South Africa, like many other developing countries, stands to benefit from novel diagnostics and drugs developed by pharmacogenomics guidance due to high prevalence of disease burden in the region. This includes both communicable (e.g., HIV/AIDS and tuberculosis) and non-communicable (e.g., diabetes and cardiovascular) diseases. For example, although only 0.7% of the world's population lives in South Africa, the country carries 17% of the global HIV/AIDS burden and 5% of the global tuberculosis burden. Nobel Peace Prize Laureate Archbishop Emeritus Desmond Tutu has coined the term Rainbow Nation, referring to a land of wealth in its many diverse peoples and cultures. It is now timely and necessary to reflect on how best to approach new genomics biotechnologies in a manner that carefully considers the public health needs and extant disease burden in the region. The aim of this paper is to document and review the advances in pharmacogenomics in South Africa and importantly, to evaluate the direction that future research should take. Previous research has shown that the populations in South Africa exhibit unique allele frequencies and novel genetic variation in pharmacogenetically relevant genes, often differing from other African and global populations. The high level of genetic diversity, low linkage disequilibrium and the presence of rare variants in these populations question the feasibility of the use of current commercially available genotyping platforms, and may partially account for genotype-phenotype discordance observed in past studies. However, the employment of high throughput technologies for genomic research, within the context of large clinical trials, combined with interdisciplinary studies and appropriate regulatory guidelines, should aid in acceleration of pharmacogenomic discoveries in high priority therapeutic areas in South Africa. Finally, we suggest that projects such as the H3Africa Initiative, the SAHGP and PGENI should play an integral role in the coordination of genomic research in South Africa, but also other African countries, by providing infrastructure and capital to local researchers, as well as providing aid in addressing the computational and statistical bottlenecks encountered at present.

We present a comprehensive overview of particulate air quality across the five major metropolitan areas of South Africa (Cape Town, Bloemfontein, Johannesburg and Tshwane (Gauteng Province), the Industrial Highveld Air Quality Priority Area (HVAPA), and Durban), based on a decadal (1 January 2000 to 31 December 2009) aerosol climatology from multiple satellite platforms and detailed analysis of ground-based data from 19 sites throughout Gauteng Province. Satellite analysis was based on aerosol optical depth (AOD) from MODIS Aqua and Terra (550 nm) and MISR (555 nm) platforms, Ångström Exponent (α) from MODIS Aqua (550/865 nm) and Terra (470/660 nm), ultraviolet aerosol index (UVAI) from TOMS, and results from the Goddard Ozone Chemistry Aerosol Radiation and Transport (GOCART) model. At continentally influenced sites, AOD, α, and UVAI reach maxima (0.12–0.20, 1.0–1.8, and 1.0–1.2, respectively) during austral spring (September–October), coinciding with a period of enhanced dust generation and the maximum integrated intensity of close-proximity and subtropical fires identified by MODIS Fire Information for Resource Management System (FIRMS). Minima in AOD, α, and UVAI occur during winter. Results from ground monitoring indicate that low-income township sites experience by far the worst particulate air quality in South Africa, with seasonally averaged PM10 concentrations as much as 136 % higher in townships that in industrial areas. We report poor agreement between satellite and ground aerosol measurements, with maximum surface aerosol concentrations coinciding with minima in AOD, α, and UVAI. This result suggests that remotely sensed data are not an appropriate surrogate for ground air quality in metropolitan South Africa. PMID:26312061

Background Completeness of vital registration remains very low in sub-Saharan Africa, especially in rural areas. Objectives To investigate trends and factors in completeness of birth and death registration in Agincourt, a rural area of South Africa covering a population of about 110,000 persons, under demographic surveillance since 1992. The population belongs to the Shangaan ethnic group and hosts a sizeable community of Mozambican refugees. Design Statistical analysis of birth and death registration over time in a 22-year perspective (1992–2014). Over this period, major efforts were made by the government of South Africa to improve vital registration. Factors associated with completeness of registration were investigated using univariate and multivariate analysis. Results Birth registration was very incomplete at onset (7.8% in 1992) and reached high values at end point (90.5% in 2014). Likewise, death registration was low at onset (51.4% in 1992), also reaching high values at end point (97.1% in 2014). For births, the main factors were mother's age (much lower completeness among births to adolescent mothers), refugee status, and household wealth. For deaths, the major factors were age at death (lower completeness among under-five children), refugee status, and household wealth. Completeness increased for all demographic and socioeconomic categories studied and is likely to approach 100% in the future if trends continue at this speed. Conclusion Reaching high values in the completeness of birth and death registration was achieved by excellent organization of the civil registration and vital statistics, a variety of financial incentives, strong involvement of health personnel, and wide-scale information and advocacy campaigns by the South African government.

In central Namibia the mountainous terrain of Namaqualand is sandwiched between the Namib Desert on the Atlantic Coast and the Kalahari Desert to the interior, where white dots mark the location of small, impermanent lakes and ponds. Namaqualand is home to numerous rare succulent plants that can survive on the region.s scant rainfall as well as fog that blows in off the ocean. Namaqualand extends south of the Orange River, which runs along the border of Namibia and South Africa and into that country.s Northern Cape region. The Orange River extends almost all the way back through the country, and where it makes a sharp southward dip in this image (at lower right), it runs through the Asbestos Mountains, names for the naturally-occurring asbestos they contain. In southwestern South Africa, high plateaus, such as the Great Karoo become mountain ridges near the coast, and the city of Cape Town is visible as a grayish area of pixels on the north shores of the horseshoe-shaped False Bay at the Cape of Good Hope.

2014-01-01

Background Despite a long history of discrimination and persisting racial disparities in smoking prevalence, little research exists on the relationship between discrimination and smoking in South Africa. Methods This analysis examined chronic (day to day) and acute (lifetime) experiences of racial and nonracial (e.g., age, gender, or physical appearance) discrimination and smoking status among respondents to the South Africa Stress and Health Study (SASH). Logistic regression models were constructed using SAS-Callable SUDAAN. Results Both chronic racial discrimination (RR=1.45, 95%CI: 1.14–1.85) and chronic nonracial discrimination (RR=1.69, 95%CI: 1.37–2.08) predicted a higher risk of smoking, but neither type of acute discrimination did. Total (sum of racial and nonracial) chronic discrimination (RR=1.46, 95%CI: 1.20–1.78) and total acute discrimination (RR=1.28, 95%CI: 1.01–1.60) predicted a higher risk of current smoking. Conclusions Racial and nonracial discrimination may be related to South African adults’ smoking behavior, but this relationship likely varies by the timing and frequency of these experiences. Future research should use longitudinal data to identify the temporal ordering of the relationships studied, include areas outside of South Africa to increase generalizability, and consider the implications of these findings for smoking cessation approaches in South Africa.

The African swine fever control zone in South Africa and its current relevance.

PubMed

Magadla, Noluvuyo R; Vosloo, Wilna; Heath, Livio; Gummow, Bruce

2016-05-23

African swine fever (ASF) has been reported in South Africa since the early 20th century. The disease has been controlled and confined to northern South Africa over the past 80 years by means of a well-defined boundary line, with strict control measures and movement restrictions north of this line. In 2012, the first outbreak of ASF outside the ASF control zone since 1996 occurred. The objective of this study was to evaluate the current relevance of the ASF control line as a demarcation line between endemic ASF (north) areas and ASF-free (south) area and to determine whether there was a need to realign its trajectory, given the recent outbreaks of ASF, global climate changes and urban development since the line's inception. A study of ASF determinants was conducted in an area 20 km north and 20 km south of the ASF control line, in Limpopo, Mpumalanga, North West and Gauteng provinces between May 2008 and September 2012. The study confirmed that warthogs, warthog burrows and the soft tick reservoir, Ornithodoros moubata, are present south of the ASF control line, but no virus or viral DNA was detected in these ticks. There appears to be an increasing trend in the diurnal maximum temperature and a decrease in humidity along the line, but the impact of these changes is uncertain. No discernible changes in minimum temperatures and average rainfall along the disease control line were observed between 1992 and 2014. Even though the reservoirs were found south of the ASF boundary line, the study concluded that there was no need to realign the trajectory of the ASF disease control line, with the exception of Limpopo Province. However, the provincial surveillance programmes for the reservoir, vector and ASF virus south of this line needs to be maintained and intensified as changing farming practices may favour the spread of ASF virus beyond the control line.

Built-Up Area and Land Cover Extraction Using High Resolution Pleiades Satellite Imagery for Midrand, in Gauteng Province, South Africa

Urban areas, particularly in developing countries face immense challenges such as climate change, poverty, lack of resources poor land use management systems, and week environmental management practices. Mitigating against these challenges is often hampered by lack of data on urban expansion, urban footprint and land cover. To support the recently adopted new urban agenda 2030 there is need for the provision of information to support decision making in the urban areas. Earth observation has been identified as a tool to foster sustainable urban planning and smarter cities as recognized by the new urban agenda, because it is a solution to unavailability of data. Accordingly, this study uses high resolution EO data Pleiades satellite imagery to map and document land cover for the rapidly expanding area of Midrand in Johannesburg, South Africa. An unsupervised land cover classification of the Pleiades satellite imagery was carried out using ENVI software, whereas NDVI was derived using ArcGIS software. The land cover had an accuracy of 85% that is highly adequate to document the land cover in Midrand. The results are useful because it provides a highly accurate land cover and NDVI datasets at localised spatial scale that can be used to support land use management strategies within Midrand and the City of Johannesburg South Africa.

At least three Trichinella species, namely Trichinella nelsoni, Trichinella britovi and Trichinella zimbabwensis, and one genotype (Trichinella T8), have been isolated from sylvatic carnivores on the African continent. With the exception of T. britovi, the other species are known to circulate in wildlife of the Kruger National Park (KNP), South Africa, and KNP neighbouring game reserves (collectively known as the greater KNP area). Lions (Panthera leo) and spotted hyenas (Crocuta crocuta) appear to be the most important reservoirs of T. nelsoni and Trichinella T8 in the KNP and surrounding areas. Interspecies predation between lions and hyenas has been implicated as a primary mode of maintaining the life cycles of these two Trichinella species. This is the first report of a mixed natural infection of T. nelsoni and Trichinella T8 in a leopard (Panthera pardus) from South Africa. Trichinella muscle larvae were identified to species level by multiplex polymerase chain reaction (PCR). Probable sources of infection, based on the known dietary preference and prey species' range of leopards, are also discussed. The described occurrence of Trichinella species in a leopard from the greater KNP area raises the question of possible sources of infection for this predator species.

In South Africa, it is intrinsic to the social transformations fueling high levels of internal migration and complex forms of mobility. While female migration in Africa has often been characterized as less prevalent than male migration, and primarily related to marriage, in South Africa a feminization of internal migration is underway, fueled by women’s increasing labor market participation. In this paper, we report sex differences in patterns, trends and determinants of internal migration based on data collected in a demographic surveillance system between 2001 and 2006 in rural KwaZulu-Natal. We show that women were somewhat more likely than men to undertake any migration, but sex differences in migration trends differed by migration flow, with women more likely to migrate into the area than men, and men more likely to out-migrate. Out-migration was suppressed by marriage particularly for women, but most women were not married; both men’s and women’s out-migrations were undertaken mainly for purposes of employment. Over half of female out-migrations (versus 35% of male out-migrations) were to nearby rural areas. The findings highlight the high mobility of this population and the extent to which gender is intimately related to the processes determining migration. We consider the implications of these findings for the measurement of migration and mobility, in particular for health and social policy and research among highly mobile populations in southern Africa.

Shortages of Human Resources for Health (HRH) in rural areas are often driven by poor working and living conditions, inadequate salaries and benefits, lack of training and career development opportunities amongst others. The South African government has adopted a human resource strategy for the health sector in 2011 aimed at addressing these challenges. This study reviews the challenges faced by health personnel against government strategies aimed at attracting and retaining health personnel in these underserved areas. The study was conducted in six primary health care service sites in the Hlabisa sub-district of Umkhanyakude, located in northern KwaZulu-Natal, South Africa. The study population comprised 25 health workers including 11 professional nurses, 4 staff nurses and 10 doctors (4 medical doctors, 3 foreign medical doctors and 3 doctors undertaking community service). Qualitative data were collected from semi-structured interviews and analysed using thematic analysis. Government initiatives including the rural allowance, deployment of foreign medical doctors and the presence of health personnel undertaking their community service in rural areas are positively viewed by health personnel working in rural health facilities. However, poor living and working conditions, together with inadequate personal development opportunities, remain unresolved challenges. It is these challenges that will continue to dissuade experienced health personnel from remaining in these underserved areas. South Africa's HRH strategy for the Health Sector 2012/13-2015/16 had highlighted the key challenges raised by respondents and identified strategies aimed at addressing these challenges. Implementation of these strategies is key to improving both living and working conditions, and providing health personnel with opportunities for further development will require inter-ministerial collaboration if the HRH 2030 objectives are to be realised.

The skills gap in nursing management in South Africa: a sectoral analysis: a research paper.

Pillay, Rubin

To identify competencies important for effective nursing management and to assess managers' proficiency therein. A lack of management capacity has been identified as the key stumbling block to health delivery in South Africa. Despite nursing managers being central to overcoming the challenges facing health care, there has been a paucity of research that empirically evaluates their skill levels. A survey was conducted among 171 senior nursing managers in South Africa using a self-administered questionnaire. Public sector managers assessed themselves as being relatively less competent than private sector managers. The largest skill gaps for public sector managers were for 'ethico-legal', 'task-related' and 'controlling' skills whereas those for private sector managers were for 'ethico-legal', 'health-related ' and 'task-related' skills. This research confirmed the lack of management capacity within the health sector and identified areas in which the skills deficit was most significant for both the public and private sectors. These findings reflect the needs of nursing managers and will be useful in the conceptualization, design and delivery of health management programmes aimed at enhancing management and leadership capacity in the health sector in South Africa.

2010 FIFA world cup South Africa: travel health issues and new options for protection against meningococcal disease.

The public health implications of large crowds gathering at a range of key global events should never be underestimated. This is especially the case with the upcoming 2010 FIFA World Cup South Africa programme where thousands of local and travelling spectators, players and officials from all over the world will be present. Although meningococcal disease contracted whilst actually travelling is relatively rare, any travel health risk assessment should involve consideration of potential exposure to and transmission of this disease where crowding occurs. In South Africa, for reasons not completely understood, the incidence of meningococcal disease is higher than in most European countries. Whilst the currently available polysaccharide vaccines can help protect travellers against meningococcal disease there are some well recognised limitations of such vaccines. These can, however, be overcome with the use of newly developed conjugated quadrivalent meningococcal vaccines. A quadrivalent conjugate vaccine should be the first choice for travellers to areas in which the risk of exposure to meningococcal disease is significant. The conjugated quadrivalent meningococcal vaccine should be recommended for all those attending or playing in the 2010 FIFA World Cup South Africa as well as similar global and regional events.

Identification of sources of environmental lead in South Africa from surface soil geochemical maps.

The bioavailability of lead in soil is of considerable importance to human and animal health. Although selective extraction has been explored as a more appropriate technique than total heavy metal analysis in environmental pollution assessments, such studies remain scarce globally and are almost non-existent in developing countries. Results for a large-scale study of extractable lead levels in undisturbed soil samples in South Africa identify several geographic areas of concern. Lead levels are considerably elevated relative to background levels in the Johannesburg urban and industrial area. Areas of active lead mining also exhibit higher surface soil values. Interestingly, areas of active and intensive coal mining activity display relatively low soil Pb values, possibly attributable to the relatively low heavy metal content of South African coal. In all instances, distribution of cadmium, a carcinogenic element, correlates with that of lead. The results demonstrate the usefulness of the quick and easy Mehlich-3 single extractant technique, an established technique in micronutrient studies, to simultaneously provide valuable environmental data for toxic metals such as Pb and Cd.

The isolated geographical situation of South Africa makes the unraveling of various parameters that influence its regional climate in time challenging. If the South African climate does not exhibit a linear correlation with global archives as suggested by some authors then the contribution of independent local data that provides direct information on the environment at a certain place and time is crucial. Fossil plant remains provide valuable information on past environmental conditions. Although few paleobotanical data are available from Southern Africa, some sites reveal rich and diverse fossil floras, most notably, Sibudu Cave, KwaZulu-Natal, South Africa, with its numerous fruits, seeds, pollen and charcoal flora. Such plant remains not only provide information on past vegetation, but also serve as a sound base for paleoclimate quantification with the Coexistence Approach (CA). Sibudu Cave has pulses of Middle Stone Age occupation separated by hiatuses that are as long as 10 ka. Pre-Still Bay, Still Bay, Howiesons Poort, post-Howiesons Poort and late and final Middle Stone Age industries are present. Variations in vegetation and the animals preyed on through time suggest that subtle environmental changes could have occurred during MIS4 and MIS3 in the Sibudu area. Whilst always semi-forested, the region may have comprised a mosaic of uneven and changeable patches of coastal forest and savanna. These in turn might have influenced the numbers of forest versus plains animals in the area. Cultural factors could also have played a part in the faunal variability observed in Sibudu. Preliminary analyses of Sibudu Cave material confirm the potential of the CA for its application on Late Pleistocene African floras. In the future, comparison with other contemporaneous sites will help quantify spatial differences in the climate of the Late Pleistocene in South Africa, and may answer if environmental changes effected the cultural development from Still Bay to late MSA industries.

Cash transfer programmes targeting children are considered an effective strategy for addressing child poverty and for improving child health outcomes in developing countries. In South Africa, the Child Support Grant (CSG) is the largest cash transfer programme targeting children from poor households. The present paper investigates the association of the duration of CSG receipt with child growth at 2 years in three diverse areas of South Africa. The study analysed data on CSG receipt and anthropometric measurements from children. Predictors of stunting were assessed using a backward regression model. Paarl (peri-urban), Rietvlei (rural) and Umlazi (urban township), South Africa, 2008. Children (n 746), median age 22 months. High rates of stunting were observed in Umlazi (28 %), Rietvlei (20 %) and Paarl (17 %). Duration of CSG receipt had no effect on stunting. HIV exposure (adjusted OR=2·30; 95 % CI 1·31, 4·03) and low birth weight (adjusted=OR 2·01, 95 % CI 1·02, 3·96) were associated with stunting, and maternal education had a protective effect on stunting. Our findings suggest that, despite the presence of the CSG, high rates of stunting among poor children continue unabated in South Africa. We argue that the effect of the CSG on nutritional status may have been eroded by food price inflation and limited progress in the provision of other important interventions and social services.

Urban and exurban residential populations in South Africa reside primarily in low-income settlements, including many townships remaining from Apartheid. Over 3 million free government homes have been built in the last 20 years, but the number of people living in informal settlements is the same as at the end of Apartheid in 1994 - a consequence of rapid urbanization. Despite availability of electricity to the vast majority of South Africans, ~80% of electrified homes in low-income areas also burn coal and/or wood as supplementary fuels for cooking and heating. These domestic burning activities represent 70-85% of total PM10mass during winter in South Africa's low-income settlements. Here we analyze data from observations of human-atmosphere systems in: 1) 19 ground monitoring sites in Gauteng Province (Johannesburg and Pretoria), and 2) an intensive sampling campaign in a township in Mpumalanga Province (Industrial Highveld). From ground monitoring, we quantitatively describe seasonal and diurnal trends in PM10 and PM2.5 typical in low-income settlements as compared with industrial and developed suburban areas, and demonstrate the impact of low-income settlements on regional air quality. We also explore the implications of economic development in townships (increased household income, expanded commercialization and widespread electricity usage) on local and regional air quality. Data from the intensive township sampling study provides a seasonal energy budget for domestic burning in low-income settlements and suggests that indoor and ambient air quality are independent systems requiring unique interventions. We conclude with a preview of innovative strategies being developed by industry, government, and academic stakeholders for a not-like-for-like emissions offset policy in South Africa, focused on investments directly into low-income settlements that are aimed at reducing PM exposure.

Attitudes and practices of pharmacists towards emergency contraception in Durban, South Africa.

Emergency contraception, which is used to prevent pregnancy following unprotected intercourse, could prove invaluable to a country like South Africa which has high fertility and pregnancy rates. However, the success of emergency contraception is dependent on the awareness, knowledge, attitudes and practices amongst health-care providers and the public towards it. The aim of this study was to assess the attitudes and practices of community pharmacists towards emergency contraception. The study was conducted in North and South Central Durban, South Africa. This questionnaire-based study sought from pharmacists the frequency of demand and supply of emergency contraception, as well as their attitudes and practices towards it. The sample included all 182 pharmacies located in the study area. A total of 96% of pharmacists had received requests for emergency contraception within the last year. On average, each pharmacist received 177 requests for emergency contraception. Sixty-nine per cent of pharmacists were in favor of making emergency contraceptive pills available without a prescription, 62% were already supplying emergency contraceptive pills without a prescription and 67% felt that it was important to increase public awareness regarding emergency contraception. Ninety-one per cent of pharmacists did not have any literature regarding emergency contraception to hand to clients, 68% had a private area in their pharmacy to counsel patients and 86% of pharmacists indicated that they discussed long-term contraception with clients. This study is the first in South Africa aimed at determining the utilization of emergency contraception. However, further studies are required in order to ascertain information that will assist in changing current health policies to improve those in reproductive health care.

Telemedicine in South Africa: success or failure?

PubMed

Gulube, S M; Wynchank, S

2001-01-01

A national telemedicine system for South Africa was planned in 1998. In the first phase, starting in 1999, 28 pilot sites were established in six provinces. The initial applications were teleradiology, tele-ultrasound for antenatal services, telepathology and tele-ophthalmology. Telemedicine equipment was connected by ISDN at 256 kbit/s. From January to September 2000, 2663 radiographic studies were performed at the three Northwest Province teleradiology transmission sites, of which 264 studies (10%) were selected for specialist radiologist reporting by teleradiology. From June to August 2000, nine antenatal care tele-ultrasound consultations were performed in the Northern Cape Province and four transfers were avoided through the use of telemedicine. One area of concern is the relatively low usage of the telemedicine system, which raises questions about its cost-effectiveness. The experience of telemedicine in South Africa confirmed, as others have found, that common problems relate to the technical and organizational challenges of introducing telemedicine.

There is a dearth of research and writing on women's cricket in South Africa. In an attempt to enhance understanding of the nature and effects of women's involvement in the game of cricket over the past 200 years, this essay offers a chronological account of the sport and the role women played in it. It draws on readings from the international scholarship on women's early involvement in sport, the fragments that have existed to date about women's cricket in South Africa and some newly discovered primary material from the 1950s onwards. The essay aims to provide a historical context and open a window for historians and social analysts into an area few knew existed before. There is now a distinctive history and subculture of cricket with multiple social dimensions for scholars to explore; here I offer some preliminary insights.

Asymptomatic malaria in refugees living in a non-endemic South African city.

Asymptomatic malaria infection in refugees is both a threat to the lives of the individuals and the public in the host country. Although South Africa has been experiencing an unprecedented influx of refugees since 1994, data on malaria infection among refugees is lacking. Such information is critical since South Africa is among the countries that have planned to eliminate malaria. The objective of this study was to determine prevalence of asymptomatic malaria infection among a refugee population living in a city of KwaZulu-Natal province, South Africa. A survey was conducted on adult refugee participants who attended a faith-based facility offering social services in a city of KwaZulu-Natal province, South Africa. The participants were screened for the presence of malaria using rapid diagnostic tests and microscopy. Demographic data for the participants were obtained using a closed ended questionnaire. Data was obtained for 303 participants consisting of 51.5% females and 47.5% males, ranging from 19 to 64 years old. More than 95% of them originated from sub-Saharan African countries. Two hundred and ninety participants provided a blood sample for screening of malaria. Of these, 3.8% tested positive for rapid diagnostic test and 5.9% for microscopy. The majority of malaria infections were due to Plasmodium falciparum. The study confirms the presence of asymptomatic malaria infections among a refugee population residing in a city of KwaZulu-Natal province that is not endemic for malaria. The results have important implications for both public health and malaria control in South Africa, particularly since the country has decided to eliminate malaria by 2018. To achieve this goal, South Africa needs to expand research, surveillance and elimination activities to include non-endemic areas, particularly with high refugee populations. We further recommend use of powerful diagnostic tests such as PCR for these interventions.

This radar image shows a close up view of a portion of the Richtersveld National Park and Orange River (top of image) in the Northern Cape Province of the Republic of South Africa. The Orange River marks the boundary between South Africa to the south and Namibia to the north. This is an area of active mining for diamonds, which were washed downstream from the famous Kimberley Diamond Area, millions of years ago when the river was much larger. The mining is focused on ancient drainages of the Orange River which are currently buried by think layers of sand and gravel. Scientists are investigating whether these ancient drainages can be seen with the radar's ability to penetrate sand cover in extremely dry regions. A mine, shown in yellow, is on the southern bank of the river in an abandoned bend which is known as an 'oxbow.' The small bright circular areas (left edge of image) west of the mine circles are fields of a large ostrich farm that are being watered with pivot irrigation. The large dark area in the center of the image is the Kubus Pluton, a body of granite rock that broke through the surrounding rocks about 550 million years ago. North is toward the upper right. The area shown is about 35 by 25 kilometers (21.8 by 15.5 miles) centered at 28.4 degrees south latitude, 16.8 degrees east longitude. Colors are assigned to different radar frequencies and polarizations as follows: red is L-band horizontally transmitted and horizontally received; green is L-band horizontally transmitted and vertically received; blue is C-band horizontally transmitted and vertically received.

Progressive and self-limiting neurodegenerative disorders in Africa: a new prominent field of research led by South Africa but without strong health policy.

PubMed

Poreau, Brice

2016-01-01

Neurodegenerative disorders are involved in mortality and morbidity of every country. A high prevalence is estimated in Africa. Neurodegenerative disorders are defined by a progressive or self-limiting alteration of neurons implied in specific functional and anatomical functions. It encompasses a various range of clinical disorders from self-limiting to progressive. Focus on public health policies and scientific research is needed to understand the mechanisms to reduce this high prevalence. We use bibliometrics and mapping tools to explore the area studies and countries involved in scientific research on neurodegenerative disorders in Africa. We used two databases: Web of Science and Pubmed. We analyzed the journals, most cited articles, authors, publication years, organizations, funding agencies, countries and keywords in Web of Science Core collection database and publication years and Medical Subject Headings in Pubmed database. We mapped the data using VOSviewer. We accessed 44 articles published between 1975 and 2014 in Web of Science Core collection Database and 669 from Pubmed database. The majority of which were after 2006. The main countries involved in research on neurodegenerative disorders in Africa the USA, the United Kingdom, France and South Africa representing the main network collaboration. Clinical neurology and Genetics hereditary are the main Web of Science categories whereas Neurosciences and Biochemistry and Molecular Biology are the main Web of Science categories for the general search "neurodegenerative disorders" not restrained to Africa. This is confirmed by Medical Subject Headings analysis from Pubmed with one more area study: Treatment. Neurodegenerative disorders research is leaded by South Africa with a network involving the USA, the UK, as well as African countries such Zambia. The chief field that emerged was on patient and hereditary as well as treatment. Public health policies were lacking fields in research whereas prevalence is estimated to be important in every country. New 17 sustainable development goals of the United Nations could help in this way.

GHG emission factors developed for the collection, transport and landfilling of municipal waste in South African municipalities

Highlights: ► An average GHG emission factor for the collection and transport of municipal solid waste in South Africa is calculated. ► A range of GHG emission factors for different types of landfills (including dumps) in South Africa are calculated. ► These factors are compared internationally and their implications for South Africa and developing countries are discussed . ► Areas for new research are highlighted. - Abstract: Greenhouse gas (GHG) emission factors are used with increased frequency for the accounting and reporting of GHG from waste management. However, these factors have been calculated for developed countries of the Northern Hemispheremore » and are lacking for developing countries. This paper shows how such factors have been developed for the collection, transport and landfilling of municipal waste in South Africa. As such it presents a model on how international results and methodology can be adapted and used to calculate country-specific GHG emission factors from waste. For the collection and transport of municipal waste in South Africa, the average diesel consumption is around 5 dm{sup 3} (litres) per tonne of wet waste and the associated GHG emissions are about 15 kg CO{sub 2} equivalents (CO{sub 2} e). Depending on the type of landfill, the GHG emissions from the landfilling of waste have been calculated to range from −145 to 1016 kg CO{sub 2} e per tonne of wet waste, when taking into account carbon storage, and from 441 to 2532 kg CO{sub 2} e per tonne of wet waste, when carbon storage is left out. The highest emission factor per unit of wet waste is for landfill sites without landfill gas collection and these are the dominant waste disposal facilities in South Africa. However, cash strapped municipalities in Africa and the developing world will not be able to significantly upgrade these sites and reduce their GHG burdens if there is no equivalent replacement of the Clean Development Mechanism (CDM) resulting from the Kyoto agreement. Other low cost avenues need to be investigated to suit local conditions, in particular landfill covers which enhance methane oxidation.« less

The primary focus of this paper is the impact of key South African leaders on the successful developments and subsequent rollbacks of South Africa`s nuclear weapons capability. It highlights the key milestones in the development of South Africa`s nuclear weapon capability. It also relates how different groups within South Africa (scientists, politicians, military and technocrats) interacted to successfully produce South Africa`s nuclear deterrent. It emphasizes the pivotal influence of the senior political leadership to pursue nuclear rollback given the disadvantages of its nuclear means to achieve vital national interests. The conclusions drawn from flu`s effort are the South African nuclearmore » program was an extreme response to its own identity Crisis. Nuclear weapons became a means to achieving a long term end of a closer affiliation with the West. A South Africa yearning to be identified as a Western nation and receive guarantees of its security rationalized the need for a nuclear deterrent. The deterrent was intended to draw in Western support to counter a feared total onslaught by Communist forces in the region. Two decades later, that same South Africa relinquished its nuclear deterrent and reformed its domestic policies to secure improved economic and political integration with the West.« less

Results from an 25 regional climate model simulations from the Coordinated Regional Downscaling Experiment Africa initiative are used to assess the projected changes in temperature and precipitation over southern Africa at two global warming levels (GWLs), namely 1.5 °C and 2.0 °C, relative to pre-industrial values, under the Representative Concentration Pathway 8.5. The results show a robust increase in temperature compared to the control period (1971–2000) ranging from 0.5 °C–1.5 °C for the 1.5 °C GWL and from 1.5 °C–2.5 °C, for the 2.0 °C GWL. Areas in the south-western region of the subcontinent, covering South Africa and parts of Namibia and Botswana are projected to experience the largest increase in temperature, which are greater than the global mean warming, particularly during the September–October–November season. On the other hand, under 1.5 °C GWL, models exhibit a robust reduction in precipitation of up to 0.4 mm day‑1 (roughly 20% of the climatological values) over the Limpopo Basin and smaller areas of the Zambezi Basin in Zambia, and also parts of Western Cape, South Africa. Models project precipitation increase of up to 0.1 mm day‑1 over central and western South Africa and in southern Namibia. Under 2.0 °C GWL, a larger fraction of land is projected to face robust decreases between 0.2 and 0.4 mm day‑1 (around 10%–20% of the climatological values) over most of the central subcontinent and parts of western South Africa and northern Mozambique. Decreases in precipitation are accompanied by increases in the number of consecutive dry days and decreases in consecutive wet days over the region. The importance of achieving the Paris Agreement is imperative for southern Africa as the projected changes under both the 1.5 °C, and more so, 2.0 °C GWL imply significant potential risks to agricultural and economic productivity, human and ecological systems health and water resources with implied increase in regional water stresses.

Will the new Consumer Protection Act prevent harm to nutritional supplement users?

Gabriels, Gary; Lambert, Mike; Smith, Pete; Hiss, Donavon

2011-07-25

BACKGROUND. There is no clear distinction between the regulation of food, supplements and medicines in South Africa. Consequently, grey areas exist in implementing the legislation, particularly in the supplement industry. The increase in supplement sales in South Africa can be attributed to aggressive marketing by manufacturers whose claims are not always supported by published peer-reviewed evidence. Such claims often go unchecked, resulting in consumers being mislead about the role of supplements. As a result of poor regulation, contaminants or adulterants in supplements may also cause insidious effects unrelated to the listed ingredients. AIM. To assess the regulations, legislation, and claims associated with nutritional supplement products in South Africa. METHOD. Peer-reviewed literature and the relevant South African statutes were consulted. RESULTS. The National Health Act incorporates the Medicine Control Council, which is charged with ensuring the safety, quality and effectiveness of medicines, and related matters, including complementary/alternative medicines. The South African Institute for Drug-Free Sport and Amendment Act provides for testing athletes for using banned substances, but currently does not concern itself with monitoring nutritional supplements for contaminants or adulterants that may cause a positive drug test, which has implications for sports participants and also the health of the general population. The implementation of the Consumer Protection Act 68 of 2008 (CPA) could protect consumer rights if it is administered and resourced appropriately. CONCLUSION. The CPA should promote greater levels of policy development, regulatory enforcement, and consumer education of South Africa's supplement industry.

Distance decay and persistent health care disparities in South Africa.

PubMed

McLaren, Zoë M; Ardington, Cally; Leibbrandt, Murray

2014-11-04

Access to health care is a particular concern given the important role of poor access in perpetuating poverty and inequality. South Africa's apartheid history leaves large racial disparities in access despite post-apartheid health policy to increase the number of health facilities, even in remote rural areas. However, even when health services are provided free of charge, monetary and time costs of travel to a local clinic may pose a significant barrier for vulnerable segments of the population, leading to overall poorer health. Using newly available health care utilization data from the first nationally representative panel survey in South Africa, together with administrative geographic data from the Department of Health, we use graphical and multivariate regression analysis to investigate the role of distance to the nearest facility on the likelihood of having a health consultation or an attended birth. Ninety percent of South Africans live within 7 km of the nearest public clinic, and two-thirds live less than 2 km away. However, 14% of Black African adults live more than 5 km from the nearest facility, compared to only 4% of Whites, and they are 16 percentage points less likely to report a recent health consultation (p < 0.01) and 47 percentage points less likely to use private facilities (p < 0.01). Respondents in the poorest income quintiles live 0.5 to 0.75 km further from the nearest health facility (p < 0.01). Racial differentials in the likelihood of having a health consultation or an attended birth persist even after controlling for confounders. Our results have two policy implications: minimizing the distance that poor South Africans must travel to obtain health care and improving the quality of care provided in poorer areas will reduce inequality. Much has been done to redress disparities in South Africa since the end of apartheid but progress is still needed to achieve equity in health care access.

The aim of this study was to determine whether dietitians in South Africa are competent to meet the requirements of working in a health care setting during a compulsory one-year community service (CS) program immediately after receiving their degree. A national survey was conducted using questionnaires to illicit information from dietitians on their training and competencies. In 2009, data were collected from both community service dietitians (CSDs) participating in community service programs in primary, secondary and tertiary health care centers in all provinces of South Africa, as well as from their provincial managers (nutrition coordinators). Sixteen (100% response) nutrition coordinators and 134 (80% response) dietitians participated in the quantitative survey. The majority of the CSDs reported that, overall, their academic training had prepared them for most aspects of nutrition service delivery. However, some recommended that academic programs include more training on community-based nutrition programs and in delivering optimal services to under-resourced communities as they believed that their competencies in these two areas were weakest. Furthermore, many CSDs were required to establish dietetics departments where none had previously existed; consequently, their capacity in management and administration needed improvement. In conclusion, academic training institutions should align their programs to the transformation of the health sector in South Africa by ensuring that dietitians are empowered to provide optimal public health nutrition services in under-resourced communities.

Tabanids are haematophagous flies feeding on livestock and wildlife. In the absence of information on the relationship of tabanid flies and protozoan parasites in South Africa and Zambia, the current study was aimed at characterizing tabanid flies collected in these two countries as well as detecting protozoan parasites they are harbouring. A total of 527 tabanid flies were collected whereby 70·2% were from South Africa and 29·8% were from Zambia. Morphological analysis revealed a total of five different genera collected from the sampled areas namely: Ancala, Atylotus, Haematopota, Philoliche and Tabanus. DNA extracted from South African Tabanus par and Tabanus taeniola tested positive for the presence of Trypanosoma congolense (Savannah) and Trypanosoma theileri whilst one member from T. par was positive for Trypanosoma brucei species. DNA extracted from Zambian tabanid flies tested positive for the presence of Besnoitia species at 1·27% (2/157), Babesia bigemina 5·73% (9/157), Theileria parva 30·11% (30/157) and 9·82% (14/157) for Trypanosoma evansi. This study is the first to report on relationship of Babesia and Theileria parasites with tabanid flies. Further investigations are required to determine the role of tabanids in transmission of the detected protozoan parasites in livestock and wildlife in South Africa and Zambia.

The full extent of the global burden of surgical disease is largely unknown; however, the scope of the problem is thought to be large. Despite the substantial burden of surgical disease, surgical services are inaccessible to many of those who need them most. There are disparities between public and private sectors in South Africa, which compounds inequitable access to surgical care. This study involved a descriptive analysis of surgical resources and included the total number of hospitals, hospital beds, surgical beds, general surgeons (specialist and nonspecialist), and the number of functional operating theatres in South Africa. A comparison was performed between the public sector resources per uninsured population and private sector resources per insured population. Hospitals were contacted during the period 01 October 2014 to 31 December 2014. Surgical resources were concentrated in metropolitan areas of urban provinces. There were striking differences between sectors when a comparison was made between patients with and without health insurance. Private resources were comparable to those available in high income countries (HICs) and were accessible to only 16% of South Africans. Improving access to surgical services in lower middle income countries (LMICs) requires addressing gaps between the public and private sector regarding infrastructure, personnel, as well as equipment. South Africa is unique in that although it is classified as an upper middle income country (UMIC), it comprises of two sectors; a public sector which has resources similar to other LMICs, and a private sector which has resources similar to HICs. These data identified disparities between geographic regions which may be contributing to ongoing inequity in South Africa, and by doing so allows for evidence-based planning towards improving surgical infrastructure and workforce.

Environmental health impacts associated with rapid urbanisation in South Africa.

PubMed

von Schirnding, Y; Yach, D

There is an urgent need for epidemiological assessments of environmental factors associated with rapid urbanisation in developing countries. Unlike the process in developed countries, urbanisation in the developing world is often associated with urban poverty, particularly on the periphery of the city where informal settlement areas develop. Population growth rates in these areas are frequently higher than in the city itself, and access to basic environmental amenities is frequently lacking. In Africa, ill-health conditions associated with rapid urbanisation, such as diarrhoea and acute respiratory infections, continue to be major causes of childhood deaths. An account is given of research being conducted in South Africa to address such problems, as well as problems related to inner-city decay, such as childhood lead exposure. There is a critical need for better inter-sectoral co-ordination between the health sector and other sectors such as housing and planning, in preventing negative health impacts associated with rapid urbanisation in the future.

Moving Across Boundaries: Migration in South Africa, 1950–2000

PubMed Central

2013-01-01

Existing knowledge about historical patterns of black internal migration in South Africa is incomplete, primarily because of the lack of good life course studies as well as the apartheid government’s suppression and censoring of data. This article provides a comprehensive picture of historical internal migration patterns with an analysis of a unique individual retrospective life history data set. This sample of the black population, collected in 2000, is the only known nationally representative life history data for South Africa; it includes all residential moves for each individual during his/her lifetime. Various mobility outcomes are analyzed: moves within/across provinces, moves within/across rural and urban areas, forced moves, moves with a nuclear family, and individual moves. The results indicate that migration significantly increased among black South Africans during the last half of the twentieth century, and that this increase began before the Pass Laws were repealed in 1986 and well before the official end of apartheid in 1991 or the first free election in 1994. The timing of this increase in migration rates suggests that migration in defiance of the Pass Laws (albeit a dangerous and desperate proposition) was a way of life for many black South Africans.

As teachers form an important part of the intervention process with childrenwho stutter in primary school, the primary aim was to describe primary school teachers'attitudes in South Africa. The secondary aim was to compare teachers' attitudes towardsstuttering in South Africa with those from a pooled group of respondents in the Public OpinionSurvey of Human Attributes-Stuttering (POSHA-S) database from different countries collectedin 2009-2014. A quantitative, cross-sectional survey research design was used. Primary schools intwo education districts in Western Cape, South Africa, were sampled. The POSHA-S, a selfadministeredquestionnaire, was completed by a cluster sample of 469 participants. Overall positive attitudes towards stuttering were found, specifically related to thepotential of people who stutter, although the result should be interpreted with caution as thesample was not homogenously positive. Teachers still had misconceptions about personalitystereotypes and the cause of stuttering. The attitudes of the South African sample were slightlymore positive compared with the samples in the current POSHA-S database. When developing stuttering intervention strategies, there are a number of keyconsiderations to take into account. The study provides a basis for speech-language therapiststo think about intervention with teachers and which areas of stuttering to consider.

Preliminary inventory and classification of indigenous afromontane forests on the Blyde River Canyon Nature Reserve, Mpumalanga, South Africa

Lötter, Mervyn C; Beck, Hans T

2004-01-01

Background Mixed evergreen forests form the smallest, most widely distributed and fragmented biome in southern Africa. Within South Africa, 44% of this vegetation type has been transformed. Afromontane forest only covers 0.56 % of South Africa, yet it contains 5.35% of South Africa's plant species. Prior to this investigation of the indigenous forests on the Blyde River Canyon Nature Reserve (BRCNR), very little was known about the size, floristic composition and conservation status of the forest biome conserved within the reserve. We report here an inventory of the forest size, fragmentation, species composition and the basic floristic communities along environmental gradients. Results A total of 2111 ha of forest occurs on Blyde River Canyon Nature Reserve. The forest is fragmented, with a total of 60 forest patches recorded, varying from 0.21 ha to 567 ha in size. On average, patch size was 23 ha. Two forest communities – high altitude moist afromontane forest and low altitude dry afromontane forest – are identified. Sub-communities are recognized based on canopy development and slope, respectively. An altitudinal gradient accounts for most of the variation within the forest communities. Conclusion BRCNR has a fragmented network of small forest patches that together make up 7.3% of the reserve's surface area. These forest patches host a variety of forest-dependent trees, including some species considered rare, insufficiently known, or listed under the Red Data List of South African Plants. The fragmented nature of the relatively small forest patches accentuates the need for careful fire management and stringent alien plant control. PMID:15287991

Quantifying green water flows for improved Integrated Land and Water Resource Management under the National Water Act of South Africa: A review on hydrological research in South Africa.

The contribution of hydrological research in South Africa in quantifying green water flows for improved Integrated Land and Water Resources Management is reviewed. Green water refers to water losses from land surfaces through transpiration (seen as a productive use) and evaporation from bare soil (seen as a non-productive use). In contrast, blue water flows refer to streamflow (surface water) and groundwater / aquifer recharge. Over the past 20 years, a number of methods have been used to quantify the green water and blue water flows. These include micrometeorological techniques (e.g. Bowen ratio energy balance, eddy covariance, surface renewal, scintillometry, lysimetry), field scale models (e.g. SWB, SWAP), catchment scale hydrological models (e.g. ACRU, SWAT) and more recently remote sensing based models (e.g. SEBAL, SEBS). The National Water Act of South Africa of 1998 requires that water resources are managed, protected and used (developed, conserved and controlled) in an equitable way which is beneficial to the public. The quantification of green water flows in catchments under different land uses has been pivotal in (a) regulating streamflow reduction activities (e.g. forestry) and the management of alien invasive plants, (b) protecting riparian and wetland areas through the provision of an ecological reserve, (c) assessing and improving the water use efficiency of irrigated pastures, fruit tree orchards and vineyards, (d) quantifying the potential impact of future land uses like bio-fuels (e.g. Jatropha) on water resources, (e) quantifying water losses from open water bodies, and (f) investigating "biological” mitigation measures to reduce the impact of polluted water resources as a result of various industries (e.g. mining). This paper therefore captures the evolution of measurement techniques applied across South Africa, the impact these results have had on water use and water use efficiency and the extent to which it supported the National Water Act of South Africa.

Instability in Parent-Child Coresidence and Adolescent Development in Urban South Africa.

There is widespread recognition of the importance of family stability for child development. South Africa presents an interesting context in which to study the consequences of family instability because of the traditionally fluid nature of household composition due to labor migration, child fostering, and non-marital fertility. More recently, the HIV pandemic has added another source of instability. Within South Africa, however, patterns of instability differ markedly across racial groups. We use the Cape Area Panel Study (CAPS) data to examine the implications of changes in parent-child coresidence for educational and sexual development of young South Africans. We show that changes in maternal and paternal coresidence have implications for the timing of sexual initiation for both black and coloured adolescents. Maternal and paternal transitions also lead to poorer educational outcomes for coloured adolescents, but parental disruptions are not significantly related to educational outcomes for blacks. These findings suggest that the implications of coresidential instability vary by race, reflecting racial differences with respect to cultural, social, and economic conditions. © 2016 The Population Council, Inc.

Marine Biodiversity in South Africa: An Evaluation of Current States of Knowledge

Griffiths, Charles L.; Robinson, Tamara B.; Lange, Louise; Mead, Angela

2010-01-01

Continental South Africa has a coastline of some 3,650 km and an Exclusive Economic Zone (EEZ) of just over 1 million km2. Waters in the EEZ extend to a depth of 5,700 m, with more than 65% deeper than 2,000 m. Despite its status as a developing nation, South Africa has a relatively strong history of marine taxonomic research and maintains comprehensive and well-curated museum collections totaling over 291,000 records. Over 3 million locality records from more than 23,000 species have been lodged in the regional AfrOBIS (African Ocean Biogeographic Information System) data center (which stores data from a wider African region). A large number of regional guides to the marine fauna and flora are also available and are listed. The currently recorded marine biota of South Africa numbers at least 12,914 species, although many taxa, particularly those of small body size, remain poorly documented. The coastal zone is relatively well sampled with some 2,500 samples of benthic invertebrate communities have been taken by grab, dredge, or trawl. Almost none of these samples, however, were collected after 1980, and over 99% of existing samples are from depths shallower than 1,000 m—indeed 83% are from less than 100 m. The abyssal zone thus remains almost completely unexplored. South Africa has a fairly large industrial fishing industry, of which the largest fisheries are the pelagic (pilchard and anchovy) and demersal (hake) sectors, both focused on the west and south coasts. The east coast has fewer, smaller commercial fisheries, but a high coastal population density, resulting in intense exploitation of inshore resources by recreational and subsistence fishers, and this has resulted in the overexploitation of many coastal fish and invertebrate stocks. South Africa has a small aquaculture industry rearing mussels, oysters, prawns, and abalone—the latter two in land-based facilities. Compared with many other developing countries, South Africa has a well-conserved coastline, 23% of which is under formal protection, however deeper waters are almost entirely excluded from conservation areas. Marine pollution is confined mainly to the densely populated KwaZulu-Natal coast and the urban centers of Cape Town and Port Elizabeth. Over 120 introduced or cryptogenic marine species have been recorded, but most of these are confined to the few harbors and sheltered sites along the coast. PMID:20689849

Alcohol policy and taxation in South Africa: an examination of the economic burden of alcohol tax.

PubMed

Ataguba, John Ele-Ojo

2012-01-01

Alcohol consumption accounts for over 4% of the global burden of disease and an even higher figure in developing countries. Several policies have been proposed to curb the negative impact of alcohol misuse. Apart from South Africa, which has witnessed a rapid development in alcohol policy, such policies are poorly developed in most African countries. South Africa uses taxation as a policy lever, in line with international evidence, to reduce alcohol consumption. However, the problem of alcohol abuse still exists. The objective of this article is to present an analysis of alcohol tax incidence for the first time in South Africa. This was done for each category of alcohol tax (wines, spirits, beer and traditional brew [sorghum beer]) and for alcohol tax as a whole. The paper also uses the results to point to the areas where a greater understanding of the issues surrounding alcohol abuse needs to be developed. Data were drawn from the 2005/06 South African Income and Expenditure Survey. Reported expenditures on alcohol beverages were used to obtain the tax component paid by households. This was done under certain assumptions relating to alcohol content and the price per litre of alcohol. Per adult equivalent consumption expenditure was used as the measure of relative living standards and concentration curves and Kakwani indices to assess relative progressivity of alcohol taxes. Statistical dominance tests were also performed. Most sorghum beer and malt beer drinkers were in the poorer quintiles. The reverse was the case for wines and spirits. Overall, alcohol tax in South Africa was regressive (Kakwani index -0.353). The individual categories were found to be regressive. The most regressive tax was that on sorghum beer (Kakwani index -1.01); the least regressive was that on spirits (Kakwani index -0.09), although this was not statistically significant at conventional levels. These results were confirmed by the test of dominance. In South Africa, there has been a renewed interest in addressing the problem of rising alcohol abuse, but the extent to which this will translate into meaningful policies is unclear. The use of an excise tax is increasingly being recognized by economists as a way to get around some of the negative effects of abusive alcohol consumption. However, this study indicates that alcohol taxes are regressive in South Africa.

Urbanization in Africa since independence.

Tarver, J D

1994-01-01

Over 185 million inhabitants were added to the urban areas of Africa between 1950 and 1990. Botswana, Lesotho, Namibia, South Africa, and Swaziland is the most highly urbanized, with 55% in 1990; while less than a quarter of Eastern Africa's population is living in urban centers. By the year 2015 more than half of Africa's population will be living in urban areas. Many parts of Africa have suffered prolonged droughts, overgrazing, locust infestations, and desertification. Millions have become refugees from natural disasters, political oppression, and rural poverty. The large exodus from Africa's rural areas has gone to cities but the large cities have attracted disproportionately large numbers of destitute migrants. Alexandria (1 million), Cairo (2.4 million) and the Witwatersrand in South Africa were the only African urban agglomerations with at least one million inhabitants in 1950. By 1990 the two Egyptian cities together had 12.7 million inhabitants and the Witwatersrand some 5 million, whereas the other 25 urban agglomerations with a million inhabitants each in 1990 had a total population of about 51 million. Lagos, Kinshasa, and Algiers ranged from 3 to 7.7 million. The capitals are the largest cities in at least 54 of the 59 countries and territories. Lagos, Nairobi, and Dar es Salaam are disproportionately larger than the next most populous cities in their countries. The 28 urban agglomerations with at least one million inhabitants had a total population of 70 million in 1990, and are projected to reach 100 million in the year 2000. Overall, Africa's urban population is projected to increase by approximately 135 million in the 1990-2000 decade (from 217 million to 352 million). About 105 million of the growth probably will occur in the smaller urban centers. The total African urban population is likely to reach one billion inhabitants within the next 50 years. It stood at 32 million in 1950. Presently, the United Nations projects 912 million urban residents (57% of the total population) by 2025.

It has been shown that ERTS imagery, particularly in the form of 1:500,000 scale false color photolithographic prints, can contribute very significantly towards facilitating and accelerating (dramatically, in some cases) resource surveys and geologic mapping. Fire mapping on a national scale becomes a feasability; numerous new geologic features, particularly lineaments, have been discovered, land use can be mapped efficiently on a regional scale and degraded areas identified. The first detailed tectonic and geomorphological maps of the Republic of South Africa will be published mainly owing to the availability of ERTS images.

Countries in Sub-Saharan Africa have recently been experiencing increases in the prevalence of obesity, type 2 diabetes mellitus (T2DM) and other non-communicable diseases in both urban and rural areas. Despite their growing influence on population health in the region, there is a paucity of epidemiological studies on the twin epidemic of obesity and T2DM, particularly in the rural communities in South Africa. We investigated the prevalence and the determinants of overall obesity among patients with T2DM in rural and semi-urban areas surrounding the town of Mthatha, South Africa. This hospital-based cross-sectional study was conducted among patients with T2DM attending the outpatient department at Mthatha General Hospital, Eastern Cape Province, South Africa. Data were obtained from 327 participants using standardized questionnaires that included items on sex, age, level of education, type of residence, employment status, smoking status, physical activity, diet and alcohol intake. After taking measurements of height and weight, participants were defined as obese if their body mass index exceeded 30 kg/m(2). Univariate and multivariate logistic regression analyses were performed to identify the determinants of obesity in our sample population. We found that 60.2% of our sample population were defined as obese. In our univariate analyses, female sex (p < 0.001), age ≥50 years (p = 0.023), rural residence (p < 0.001), excessive alcohol intake (p = 0.002), current cigarette smoking (p < 0.001), level of education (p < 0.001), regular consumption of soft drinks (p < 0.001) and unemployment (p = 0.043) were found to be positively and significantly associated with obesity. In the multivariate logistic regression analysis, female sex (p < 0.001), unemployment (p = 0.012) and level of education (p < 0.001) were found to be independent determinants of obesity. We found that female sex, educational attainment, unemployment and current cigarette smoking were positively associated with obesity among the study participants. Lifestyle changes, poverty reduction and public education are urgently needed to address the growing obesity epidemic in rural areas of South Africa.

Tuberculosis (TB) prevention, including infection control, is a key element in the strategy to end the global TB epidemic. While effective infection control requires all health system components to function well, this is an area that has not received sufficient attention inSouth Africa despite the availability of policy and guidelines. To describe the state of implementation of TB infection control measures in a high-burden metro in South Africa. The research was undertaken in a high TB- and HIV-burdened metropolitan area of South Africa. More specifically, the study sites were primary health care facilities (PHC), thatamong other services also diagnosed TB. A cross-sectional survey, focusing on the World Health Organization levels of infection control, which included structured interviews with nurses providing TB diagnosis and treatment services as well as observations, at all 41 PHC facilities in a high TB-burdened and HIV-burdened metro of South Africa. Tuberculosis infection control was poorly implemented, with few facilities scoring 80% and above on compliance with infection control measures. Facility controls: 26 facilities (63.4%) had an infection control committee and 12 (29.3%) had a written infection control plan. Administrative controls: 26 facilities (63.4%) reported separating coughing and noncoughing patients, while observations revealed that only 11 facilities (26.8%) had separate waiting areas for (presumptive) TB patients. Environmental controls: most facilities used open windows for ventilation (n = 30; 73.2%); however, on the day of the visit, only 12 facilities (30.3%) had open windows in consulting rooms. Personal protective equipment: 9 facilities (22%) did not have any disposable respirators in stock and only 9 respondents (22%) had undergone fit testing. The most frequently reported barrier to implementing good TBinfection control practices was lack of equipment (n = 22; 40%) such as masks and disposable respirators, as well as the structure or layout of the PHC facilities. The main recommendation to improve TB infection control was education for patients and health care workers (n = 18; 33.3%). All levels of the health care system should be engaged to address TB prevention and infection control in PHC facilities. Improved infection control will address the nosocomial spread of TB in health facilities and keep health care workers and patients safe from infection.

One serious concern of health policymakers in South Africa is the fact that there is no national data on the dietary intake of adult South Africans. The only national dietary study was done in children in 1999. Hence, it becomes difficult to plan intervention and strategies to combat malnutrition without national data on adults. The current review consequently assessed all dietary studies in adults from 2000 to June 2015 in an attempt to portray typical adult dietary intakes and to assess possible dietary deficiencies. Notable findings were that, in South Africa micronutrient deficiencies are still highly prevalent and energy intakes varied between very low intakes in informal settlements to very high intakes in urban centers. The most commonly deficient food groups observed are fruit and vegetables, and dairy. This has been attributed to high prices and lack of availability of these food groups in poorer urban areas and townships. In rural areas, access to healthy foods also remains a problem. A national nutrition monitoring system is recommended in order to identify dietary deficiencies in specific population groups. PMID:26404371

The South African Astronomical Observatory (SAAO) observing station near Sutherland, Northern Cape in South Africa, is one of the darkest sites in the world for optical and IR astronomy. The SAAO hosts and operates several facilities, including the Southern African Large Telescope (SALT) and a number of international robotic telescopes. To ensure that the conditions remain optimal for astronomy, legislation called the Astronomy Geographic Advantage (AGA) Act, of 2007, was enacted. The Act empowers the Department of Science and Technology (DST) to regulate issues that pose a threat to optical and/or radio astronomy in areas declared Astronomy Advantage Areas in South Africa. For optical astronomy, the main challenges are those posed by light and dust pollution as result of wind energy developments, and petroleum gas and oil exploration/exploitation in the area. We give an update of possible threats to the quality of the night skies at SAAO, and the challenges relating to the AGA Act implementation and enforcement. We discuss measures that are put in place to protect the Observatory, including a study to quantify the threat by a planned wind energy facility.

A GIS approach to seismic risk assessment with an application to mining-related seismicity in Johannesburg, South Africa

2017-08-01

The majority of seismic activity in South Africa is related to extensive mining operations, usually in close proximity to densely populated areas where a relatively weak seismic event could cause damage. Despite a significant decrease in mining operations in the Witwatersrand area, the number of seismic events appears to be increasing and is attributed to the acid mine drainage problem. The increased seismicity is raising concern amongst disaster management centres and in the insurance industry. A better understanding is required of the vulnerability and the size of the potential loss of people and infrastructure in densely populated Johannesburg and its surrounding areas. Results of a deterministic seismic risk, vulnerability, and loss assessment are presented by making use of a geographic information system (GIS). The results illustrate the benefits of using GIS and contribute to a better understanding of the risk, which can assist in improving disaster preparedness.

Modelling the distribution of tritium in groundwater across South Africa to assess the vulnerability and sustainability of groundwater resources in response to climate change

Groundwater is critical for sustaining human populations, especially in semi-arid to arid areas, where surface water availability is low. Shallow groundwater is usually abstracted for this purpose because it is the easiest to access and assumed to be renewable and regularly recharged by precipitation. Renewable, regularly recharged groundwater is also called modern groundwater, ie groundwater that has recently been in contact with the atmosphere. Tritium can be used to determine whether or not a groundwater resource is modern because the half-life of tritium is only 12.36 years and tritium is dominantly produced in the upper atmosphere and not in the rock mass. For this reason, groundwater with detectable tritium activities likely has a residence age of less than 50 years. In this study, tritium activities in 277 boreholes distributed across South Africa were used to develop a national model for tritium activity in groundwater in order to establish the extent of modern groundwater across South Africa. The tritium model was combined with modelled depth to water using 3079 measured static water levels obtained from the National Groundwater Archive and validated against a separate set of 40 tritium activities along the west coast of South Africa. The model showed good agreement with the distribution of rainfall which has been previously documented across the globe (Gleeson et al., 2015), although the arid Karoo basin in south west South Africa shows higher than expected tritium levels given the very low regional precipitation levels. To assess the vulnerability of groundwater to degradation in quality and quantity, the tritium model was incorporated into a multi-criteria evaluation (MCE) model which incorporated other indicators of groundwater stress including mean annual precipitation, mean annual surface temperature, electrical conductivity (as a proxy for groundwater salinization), potential evaporation, population density and cultivated land usage. The MCE model was then forward projected using predicted climate change from the ECHAM5/MPI-OM model for SRES high emission scenario A2. The resultant groundwater vulnerability map for South Africa indicates that groundwater across large parts of western South Africa, particularly along the west coast and Northern Cape regions, is extremely vulnerable to deterioration in both quality and quantity and this deterioration is most strongly linked to mean annual precipitation and potential evaporation. Accordingly, the west coast region of South Africa is now, and will remain in the future, the most vulnerable region to climate change in South Africa. Further investigation of the predicted evolution of climate, biodiversity and agricultural capacity in this region will be critical for developing sustainable groundwater management protocols.

We describe the genesis and programs of the African Laser Centre (ALC), which is an African nonprofit network of laser users that is based in Pretoria, South Africa. Composed of over thirty laboratories from countries throughout the continent of Africa, the ALC has the mission of enhancing the application of lasers in research and education. Its programs include grants for research and training, equipment loans and donations, student scholarships, faculty grants for visits to collaborators' institutions, conferences, and technician training. A long-term goal of the ALC is to bring a synchrotron light source to Africa, most probably to South Africa. One highly popular program is the biennial conference series called the US-Africa Advanced Studies Institute, which is funded by the ALC in collaboration with the U.S. National Science Foundation and the International Center for Theoretical Physics in Trieste. The Institutes typically bring about thirty faculty and graduate students from the U.S. to venues in Africa in order to introduce U.S. and African graduate students to major breakthroughs in targeted areas that utilize lasers. In this presentation, we will summarize the ALC achievements to date and comment on the path forward.

Paleocene pycnodont fishes from Jabal Umm Himar, Harrat Hadan area, Kingdom of Saudi Arabia

Madden, Gary T.

1983-01-01

Three species of Pycnodus, a genus of extinct holostean fishes, have been identified from the Paleocene of Jabal Umm Himar, Harrat Hadan area, south-central Saudi Arabia, an area that was contiguous with Africa during the Early Tertiary. One of the species is larger than any species identified from the Early Tertiary of Africa. Its lower teeth are from 60 to 100 percent wider and 50 percent longer than those in P. mokattamensis, hitherto the largest species known from Africa. The second species, the most poorly represented of the three, is in dental size roughly 40 percent as large as the first species or about the same size as P. variabilis of Africa. The third species is small and, although the position of its teeth cannot be determined, this species clearly is distinct from the two other pycnodonts from Jabal Umm Himar.

Burn care in South Africa: a micro cosmos of Africa.

Rode, H; Cox, S G; Numanoglu, A; Berg, A M

2014-07-01

Burn injuries in Africa are common with between 300,000 and 17.5 million children under 5 years sustaining burn injuries annually, resulting in a high estimated fatality rate. These burns are largely environmentally conditioned and therefore preventable. The Western Cape Province in South Africa can be regarded as a prototype of paediatric burns seen on the continent, with large numbers, high morbidity and mortality rates and an area inclusive of all factors contributing to this extraordinary burden of injury. Most of the mechanisms to prevent burns are not easily modified due to the restraint of low socio-economic homes, overcrowding, unsafe appliances, multiple and complex daily demands on families and multiple psycho-social stressors. Children <4 years are at highest risk of burns with an average annual rate of 6.0/10,000 child-years. Burn care in South Africa is predominantly emergency driven and variable in terms of organization, clinical management, facilities and staffing. Various treatment strategies were introduced. The management of HIV positive children poses a problem, as well as the conflict of achieving equity of burn care for all children. Without alleviating poverty, developing minimum standards for housing, burn education, safe appliances and legislation, we will not be able to reduce the "curse of poor people" and will continue to treat the consequences.

The Africa South America Intercontinental Teleconnection.

2004-07-01

The influence of heating over Africa on the South American precipitation climatology, and the influence of South America on Africa, is examined through the application of GCM simulations with idealized boundary conditions and perpetual solstice (January and July) conditions.The presence of Africa is associated with a pronounced (up to 4 mm day-1) decrease in precipitation in Brazil's Nordeste region during austral summer. Low-level moisture divergence and dry-air advection associated with the downbranch of a Walker circulation induced by heating over southern Africa is amplified over the Nordeste due to the response of the land surface. The response is much smaller during austral winter due to differences in the heat source over Africa and a reduced sensitivity in the surface heat balance over tropical South America. Forcing from South America in January shifts the position of the South Indian convergence zone (SICZ) to the southwest over southern Africa in association with the formation of the South Atlantic convergence zone (SACZ). In July, a Rossby wave train generated over South America induces a response in the surface temperature of Africa that leads to stronger precipitation in central and western Africa.This study suggests a zonal mode of variability for South American and African circulation and precipitation fields. The resulting perturbations depend as much on land surface atmosphere interactions as on the direct forcing from the adjacent continent, and the mechanisms are highly nonlinear.

The purpose of this study was to estimate the economic burden of violence against children in South Africa. We assembled summative estimates of lifetime prevalence, calculated the magnitude of associations with negative outcomes, and thereby estimated the economic burden of violence against children. According to our calculations, 2.3 million and 84,287 disability-adjusted life-years (DALYs) lost in South Africa in 2015 were attributable to nonfatal and fatal violence against children, respectively. The estimated economic value of DALYs lost to violence against children (including both fatal and nonfatal) in South Africa in 2015 totalled ZAR173 billion (US $13.5 billion)-or 4.3% of South Africa's gross domestic product (GDP) in 2015. In addition, the reduced earnings attributable to childhood physical violence and emotional violence in South Africa in 2015 were ZAR25.2 billion (US $2.0 billion) and ZAR9.6 billion (US $750 million), respectively. In addition, South Africa spent ZAR1.6 billion (US $124 million) on child care and protection in fiscal year 2015/2016, many of which costs are directly related to violence against children. This study confirms the importance of prioritising violence against children as a key social and economic concern for South Africa's future.

Platinum and Gold Mining in South Africa: The Context of the Marikana Massacre.

Cairncross, Eugene; Kisting, Sophia

2016-02-01

Mining is a source of extraordinary wealth, but its benefits often do not accrue to the workers and communities most involved. This paper presents two case studies of mining in South Africa to reflect on the history and legacy of mining both through observation and through the voices of affected communities. Interviews and observations on field visits to the platinum and gold mining areas of South Africa in the immediate aftermath of the Marikana massacre highlight this legacy--including vast quantities of tailings dumps and waste rock, lakes of polluted water and a devastated physical and social environment, high unemployment, high rates of occupational injury and disease including silicosis with co-morbidities, absent social security, and disrupted rural and agricultural communities. Exploitative conditions of work and the externalization of the health and environmental costs of mining will require international solidarity, robust independent trade unions, and a commitment to human rights. © The Author(s) 2016.

Metals and their ecological impact on beach sediments near the marine protected sites of Sodwana Bay and St. Lucia, South Africa.

A baseline study on metal concentrations in sediments was initiated from the Sodwana Bay and St. Lucia, adjacent to marine protected areas (MPAs) of South Africa. They were analysed to identify the acid leachable metal (ALM) (Fe, Mg, Mn, Cr, Cu, Mo, Ni, Co, Pb, Cd, Zn and Hg) concentration pattern. Metal distribution in 65 sediment samples exhibits higher abundances of Cr, Mo, Cd and Hg compared to the Upper Continental Crust. We relate the enrichment of these metals to beach placer deposits and activities related to former gold mining. Geochemical indices affirmed that Cr and Hg caused contamination, and Hg posed ~90% harmful effect on the biological community. These beach sediments, however, host lower metal concentrations compared to many worldwide beaches and other beaches in South Africa. This study suggests that it is largely unaffected by human activities, however, the overabundance of Hg demands regular monitoring. Copyright © 2017 Elsevier Ltd. All rights reserved.

South Africa has the highest number of people living with HIV in the world (over 6 million) as well as a rapidly aging population, with 15% of the population aged 50 and over. High HIV prevalence in rural former apartheid homeland areas suggests substantial aging with HIV and acquisition of HIV at older ages. We develop a life course approach to HIV vulnerability, highlighting the rise and fall of risk and protection as people age, as well as the role of contextual density in shaping HIV vulnerability. Using this approach, we draw on an innovative multi-method data set collected within the Agincourt Health and Demographic Surveillance System in South Africa, combining survey data with 60 nested life history interviews and 9 community focus group interviews. We examine HIV risk and protective factors among adults aged 40-80, as well as how and why these factors vary among people at older ages. Copyright © 2015 Elsevier Ltd. All rights reserved.

This paper reports part of the findings of a study which exposed sexual violence in schools for learners with mild intellectual disability in South Africa. Special attention was paid on factors contributing to such a problem. Data were collected using focus groups and individual interviews with 16 learners with mild intellectual disability at two special schools in South Africa. This was followed by individual interviews with the school nurse and social worker, and an analysis of schools' books of incidents. Factors contributing to sexual violence at schools for learners with mild intellectual disability included: (i) peer pressure, (ii) concealment of reported incidents of sexual violence, (iii) unsupervised areas linked to schools and (iv) arranged relationships. The following suggestions are put forth: (i) awareness programmes, (ii) sensitization of teachers about the consequences and prevention of sexual violence, (iii) boundaries within which the arranged relationship occurs, (iv) intensification of sexuality education and (v) supervision around the school premises. © 2015 John Wiley & Sons Ltd.

Telerehabilitation in South Africa - is there a way forward?

South Africa, like the rest of sub-Saharan Africa, has a disproportionate burden of disease and a shortage of health professionals. Telemedicine has been identified as a possible way of overcoming part of the problem but telemedicine has not been widely adopted. In the public sector hospitals in South Africa which serve 82% of the population there are 2.5 physiotherapists and 2 occupational therapists per 100,000 people served. The extent of telerehabilitation in South Africa is unknown. A literature review of telerehabilitation found no papers from South Africa. A survey of the heads of university departments of physiotherapy, occupational therapy and speech and language pathology revealed limited knowledge of telerehabilitation. Telerehabilitation services are confined to follow-up of patients at some institutions by telephone, fax or email. There is need to raise awareness among therapists if telerehabilitation is to become a reality in South Africa. Future actions are outlined.

In pursuit of empowerment: Sensei Nellie Kleinsmidt, race and gender challenges in South Africa.

PubMed

Jones, D E

2001-01-01

This chapter traces the way in which Nellie Kleinsmidt, known as the grandmother of karate in Africa, has negotiated discriminatory practices and overcome race and gender-related struggles, including the struggle to free the female body, in pursuit of empowerment. It explores her expectations and the constraints and frustrations she experienced, as well as the many contributions she has made to women's karate in South Africa. Nellie Kleinsmidt's karate career, which began in 1965, coincided with the early developments of South African karate. As a woman of colour her life and karate career were significantly shaped by apartheid legislation. It divided the country into areas of occupancy and residency according to race and was designed to prevent contact between the people of the government defined race groups. Black karate-kas were prohibited by law from practising karate in white designated areas. Lack of facilities and qualified instructors in areas allocated to Kleinsmidt's race group meant that she received very little formal karate instruction between 1966 and 1973. Soon after, she met Johan Roux, a white male. He was to become her chief karate instructor and life-long companion. They defied the apartheid legislation and in 1978 set up home together. They organized defiance campaigns, resisting the pressures from government to close their dojo because of its non-racial policies. Freeing her body at the broader political level involved the abolition of the race categories and all other apartheid legislation which impacted on her life choices and experiences. Initially this struggle and that of freeing her body occurred simultaneously. In her ongoing struggle against gender discrimination in the sport, it was in karate that Nellie Kleinsmidt could strive for the personal empowerment she sought. She could however not translate this into freedom in South African society itself. The impact of apartheid legislation together with the imposition of a sports moratorium by the South African Council on Sports (SACOS), hindered the growth of Nellie Kleinsmidt's karate career, yet she managed to obtain her sixth Dan Black Belt in 1998. This was a remarkable achievement given the constraints she had to overcome. In karate, Kleinsmidt was often viewed as a female first. The problem of female access is exacerbated by the overwhelming number of male instructors perpetuating the notion that the martial arts are inherently male sports. Accessing the various levels of karate has involved claiming physical and symbolic space on the dojo floor as well as involvement in the decision-making arenas of karate. In 1992 with the unification of karate in South Africa, Sensei Nellie began to extend her involvement with the refereeing arena and jointly established a Women's Karate Forum in her province. She has subsequently become a South African national referee and has earned the status of continental judge with the Union of African Karate Federation (UFAK). Nellie Kleinsmidt is the first and only woman of colour to have been appointed to the Referee's Board of South Africa and the only woman of colour in Africa to have obtained a sixth Dan Black belt.

Assessment of air pollution impacts on vegetation in South Africa

1989-01-01

Field surveys and biomonitoring network experiments were conducted in selected areas in South Africa to assess possible air pollution damage to vegetation. During field surveys, atmospheric fluoride was identified as an important pollutant that damaged vegetation in residential areas north of Cape Town. Gaseous air pollutants, including acid deposition and acidic mist, probably play a major role in the development of characteristic air pollution injury symptoms observed on pine trees in the Eastern Transvaal area. The impact of urban air pollution in the Cape Town area was evaluated by exposing bio-indicator plants in a network of eight biomonitoring network stationsmore » from June 1985 to May 1988. Sensitive Freesia and Gladiolus cultivars were used to biomonitor atmospheric fluoride, while a green bean cultivar was used as a biomonitor of atmospheric sulfur dioxide and ozone. At one location, bio-indicator plants were simultaneously exposed in a biomonitoring network station, open-top chambers, as well as in open plots. The responses of plants grown under these different conditions were compared.« less

Racial and non-racial discrimination and smoking status among South African adults 10 years after apartheid.

Despite a long history of discrimination and persisting racial disparities in smoking prevalence, little research exists on the relationship between discrimination and smoking in South Africa. This analysis examined chronic (day-to-day) and acute (lifetime) experiences of racial and non-racial (eg, age, gender or physical appearance) discrimination and smoking status among respondents to the South Africa Stress and Health study. Logistic regression models were constructed using SAS-Callable SUDAAN. Both chronic racial discrimination (RR=1.45, 95% CI 1.14 to 1.85) and chronic non-racial discrimination (RR=1.69, 95% CI 1.37 to 2.08) predicted a higher risk of smoking, but neither type of acute discrimination did. Total (sum of racial and non-racial) chronic discrimination (RR=1.46, 95% CI 1.20 to 1.78) and total acute discrimination (RR=1.28, 95% CI 1.01 to 1.60) predicted a higher risk of current smoking. Racial and non-racial discrimination may be related to South African adults' smoking behaviour, but this relationship likely varies by the timing and frequency of these experiences. Future research should use longitudinal data to identify the temporal ordering of the relationships studied, include areas outside of South Africa to increase generalisability and consider the implications of these findings for smoking cessation approaches in South Africa.

2016-01-01

Background Physical, emotional and sexual abuse of children is a major problem in South Africa, with severe negative outcomes for survivors. To date, no known studies have used data directly obtained from community-based samples of children to investigate prevalence, incidence, locations and perpetrators of child abuse victimisation. This study aims to investigate prevalence and incidence, perpetrators, and locations of child abuse victimisation in South Africa using a multicommunity sample. Methods 3515 children aged 10–17 years (56.6% female) were interviewed from all households in randomly selected census enumeration areas in two South African provinces. Child self-report questionnaires were completed at baseline and at 1-year follow-up (96.7% retention). Results Prevalence was 56.3% for lifetime physical abuse (18.2% past-year incidence), 35.5% for lifetime emotional abuse (12.1% incidence) and 9% for lifetime sexual abuse (5.3% incidence). 68.9% of children reported any type of lifetime victimisation and 27.1% reported lifetime multiple abuse victimisation. Main perpetrators of abuse were reported: for physical abuse, primary caregivers and teachers; for emotional abuse, primary caregivers and relatives; and for sexual abuse, girlfriend/boyfriends or other peers. Conclusions This is the first study assessing current self-reported child abuse through a large, community-based sample in South Africa. Findings of high rates of physical, emotional and sexual abuse demonstrate the need for targeted and effective interventions to prevent incidence and re-victimisation. PMID:26962202

ISS024-E-012749 (28 Aug. 2010) --- Maseru, Lesotho is featured in this image photographed by an Expedition 24 crew member on the International Space Station. Maseru is the capital city of the Kingdom of Lesotho and is located along the northwestern border of the country with the Republic of South Africa. The footprint of the urban area, recognizable by street grids and distinctive blue-roofed industrial buildings at center, is only just visible against the surrounding landscape. The city has expanded eightfold (to 230,000 today) since independence from the United Kingdom of Great Britain and Northern Ireland in 1966, and is now home to one in five inhabitants in the country. The Caledon (or Mohokare) River flows adjacent to Maseru and forms a part of the border between Lesotho and South Africa. Locally, the border extends from approximately top center left to bottom center right, with the cities of Ladybrand and Manyatseng located in South Africa. Moshoeshoe I International Airport (left) provides access to the capital. Major industries in the city include flour mills, and footwear and textile companies. Tourism is also a growing part of the local economy. The Kingdom of Lesotho is completely landlocked by the surrounding Republic of South Africa. Major landforms visible in the image near Maseru include the Qeme and Berea Plateaus to the south and east respectively; these are erosional remnants of widespread horizontally layered sedimentary rocks that formed in the Karoo Basin during the Upper Triassic Period (approximately 200–229 million years ago), according to scientists.

Epidemiologic and Environmental Risk Factors of Rift Valley Fever in Southern Africa from 2008 to 2011.

PubMed

Glancey, Margaret M; Anyamba, Assaf; Linthicum, Kenneth J

2015-08-01

Rift Valley fever (RVF) outbreaks have been associated with periods of widespread and above-normal rainfall over several months. Knowledge on the environmental factors influencing disease transmission dynamics has provided the basis for developing models to predict RVF outbreaks in Africa. From 2008 to 2011, South Africa experienced the worst wave of RVF outbreaks in almost 40 years. We investigated rainfall-associated environmental factors in southern Africa preceding these outbreaks. RVF epizootic records obtained from the World Animal Health Information Database (WAHID), documenting livestock species affected, location, and time, were analyzed. Environmental variables including rainfall and satellite-derived normalized difference vegetation index (NDVI) data were collected and assessed in outbreak regions to understand the underlying drivers of the outbreaks. The predominant domestic vertebrate species affected in 2008 and 2009 were cattle, when outbreaks were concentrated in the eastern provinces of South Africa. In 2010 and 2011, outbreaks occurred in the interior and southern provinces affecting over 16,000 sheep. The highest number of cases occurred between January and April but epidemics occurred in different regions every year, moving from the northeast of South Africa toward the southwest with each progressing year. The outbreaks showed a pattern of increased rainfall preceding epizootics ranging from 9 to 152 days; however, NDVI and rainfall were less correlated with the start of the outbreaks than has been observed in eastern Africa. Analyses of the multiyear RVF outbreaks of 2008 to 2011 in South Africa indicated that rainfall, NDVI, and other environmental and geographical factors, such as land use, drainage, and topography, play a role in disease emergence. Current and future investigations into these factors will be able to contribute to improving spatial accuracy of models to map risk areas, allowing adequate time for preparation and prevention before an outbreak occurs.

2013-03-01

To develop a model for identifying areas at high risk for sporadic measles outbreaks based on an analysis of factors associated with a national outbreak in South Africa between 2009 and 2011. Data on cases occurring before and during the national outbreak were obtained from the South African measles surveillance programme, and data on measles immunization and population size, from the District Health Information System. A Bayesian hierarchical Poisson model was used to investigate the association between the risk of measles in infants in a district and first-dose vaccination coverage, population density, background prevalence of human immunodeficiency virus (HIV) infection and expected failure of seroconversion. Model projections were used to identify emerging high-risk areas in 2012. A clear spatial pattern of high-risk areas was noted, with many interconnected (i.e. neighbouring) areas. An increased risk of measles outbreak was significantly associated with both the preceding build-up of a susceptible population and population density. The risk was also elevated when more than 20% of infants in a populous area had missed a first vaccine dose. The model was able to identify areas at high risk of experiencing a measles outbreak in 2012 and where additional preventive measures could be undertaken. The South African measles outbreak was associated with the build-up of a susceptible population (owing to poor vaccine coverage), high prevalence of HIV infection and high population density. The predictive model developed could be applied to other settings susceptible to sporadic outbreaks of measles and other vaccine-preventable diseases.

Genetic analyses of population structure can be placed in explicit environmental contexts if appropriate environmental data are available. Here, we use high-coverage and high-resolution oceanographic and genetic sequence data to assess population structure patterns and their potential environmental influences for humpback dolphins in the Western Indian Ocean. We analyzed mitochondrial DNA data from 94 dolphins from the coasts of South Africa, Mozambique, Tanzania and Oman, employing frequency-based and maximum-likelihood algorithms to assess population structure and migration patterns. The genetic data were combined with 13 years of remote sensing oceanographic data of variables known to influence cetacean dispersal and population structure. Our analyses show strong and highly significant genetic structure between all putative populations, except for those in South Africa and Mozambique. Interestingly, the oceanographic data display marked environmental heterogeneity between all sampling areas and a degree of overlap between South Africa and Mozambique. Our combined analyses therefore suggest the occurrence of genetically isolated populations of humpback dolphins in areas that are environmentally distinct. This study highlights the utility of molecular tools in combination with high-resolution and high-coverage environmental data to address questions not only pertaining to genetic population structure, but also to relevant ecological processes in marine species.

Description of an outbreak of highly pathogenic avian influenza in domestic ostriches (Struthio camelus) in South Africa in 2011.

2016-06-01

In 2011, the commercial ostrich production industry of South Africa experienced an outbreak of highly pathogenic avian influenza (HPAI), subtype H5N2. Surveillance using antibody and antigen detection revealed 42 infected farms with a between-farm prevalence in the affected area of 16%. The outbreak was controlled using depopulation of infected farms, resulting in the direct loss of 10% of the country's domestic ostrich population. Various factors in the ostrich production system were observed that could have contributed to the spread of the virus between farms, including the large number of legal movements of ostriches between farms, access of wild birds to ostrich camps and delays in depopulation of infected farms. Negative effects on the ostrich industry and the local economy of the ostrich-producing area were observed as a result of the outbreak and the disease control measures applied. Prevention and control measures applied as a result of avian influenza in South Africa were informed by this large outbreak and the insights into epidemiology of avian influenza in ostriches that it provided, resulting in stricter biosecurity measures required on every registered ostrich farm in the country.

2010-11-01

In 2006, De Beers Consolidated Diamond Mines in South Africa entered into a partnership with the Soul City Institute for Health and Development Communications to implement an HIV and AIDS Community Training Partnership Program (CTPP), initially in five diamond mining areas in three provinces of South Africa. The aim of CTPP was to improve HIV knowledge and to contribute to positive behavior changes in the targeted populations. This paper describes the evaluation of the CTPP, one year after implementation. The evaluation combined qualitative interviews with key informants and trainers and a post-intervention survey of 142 community members. The successes of the CTPP included capacity building of trainers through an innovative training approach and HIV and AIDS knowledge transfer to community trainers and targeted communities in remote mining towns. The Soul City edutainment brand is popular and emerged as a major reason for success. Challenges included insufficient attention paid to contextual factors, resource constraints and the lack of a monitoring and evaluation framework. Independent evaluations are useful to strengthen program implementation. In remote areas and resource constraint settings, partnerships between non-governmental organisations and corporations may be required for successful community HIV and AIDS initiatives.

AN ANALYSIS OF THE INEQUALITIES BETWEEN THE PUBLIC AND PRIVATE SECTOR IN SOUTH AFRICA.

The full extent of the global burden of surgical disease is largely unknown, however, the scope of the problem is thought to be large. Despite the substantial burden of surgical disease, surgical services are inaccessible to many of those who need them most. There are disparities between public and private sectors in South Africa, which compounds inequitable access to surgical care. This study involved a descriptive analysis of surgical resources and included the total number of hospitals, of hospital beds, the number of surgical beds, the number of general surgeons (specialist and non-specialist), and the number of functional operating theatres in South Africa. A comparison was performed between the public and private sectors. Hospitals were contacted during the period from the 1st October 2014 until the 31st of December 2014. Surgical resources were concentrated in metropolitan areas of urban provinces. There were striking differences between the public and private sectors, where private resources were comparable to those available in high income countries (HICs). Improving access to surgical services in lower middle income countries (LMICs) requires addressing gaps between the public and private sector regarding infrastructure, personnel, as well as equipment. South Africa is unique in that although it is classified as an upper middle income country (UMIC), is comprises of two sectors; a public sector which has resources similar to other LMICs, and a private sector which has resources similar to HICs. These data identified disparities between geographic regions which may be contributing to ongoing inequity in South Africa, and by doing so allows for evidence-based planning towards improving surgical infrastructure and workforce.

Terrorism in South Africa.

MacFarlane, Campbell

2003-01-01

The Republic of South Africa lies at the southern tip of the African continent. The population encompasses a variety of races, ethnic groups, religions, and cultural identities. The country has had a turbulent history from early tribal conflicts, colonialisation, the apartheid period, and post-apartheid readjustment. Modern terrorism developed mainly during the apartheid period, both by activities of the state and by the liberation movements that continued to the time of the first democratic elections in 1994, which saw South Africa evolve into a fully representative democratic state with equal rights for all. Since 1994, terrorist acts have been criminal-based, evolving in the Cape Town area to political acts, largely laid at the feet of a predominantly Muslim organisation, People against Gangsterism and Drugs, a vigilant organisation allegedly infiltrated by Muslim fundamentalists. Along with this, has been terrorist activities, mainly bombings by disaffected members of white, right-wing groups. In the apartheid era, a Draconian series of laws was enacted to suppress liberation activities. After 1994, most of these were repealed and new legislation was enacted, particularly after the events of 11 September 2001; this legislation allows the government to act against terrorism within the constraints of a democratic system. Disaster management in South Africa has been largely local authority-based, with input from provincial authorities and Civil Defence. After 1994, attempts were made to improve this situation, and national direction was provided. After 11 September 2001, activity was increased and the Disaster Management Act 2002 was brought into effect. This standardized disaster management system at national, provincial, and local levels, also facilites risk assessment and limitation as well as disaster mitigation. The potential still exists for terrorism, mainly from right-wing and Muslim fundamentalist groups, but the new legislation should stimulate disaster management in South Africa to new and improved levels.

The Lubombo Spatial Development Initiative (LSDI) was a tri-country project between South Africa, Swaziland and Mozambique with the aim of accelerating socio-economic development in the region. The malaria component of the project was introduced to decrease the transmission of malaria in the region. This goal was met but with termination of this project resulted in an upsurge of malaria cases in the sub-region mainly as a result of migration from high transmission areas to low transmission ones. The movement of people across borders in southern Africa remains a challenge in sustaining malaria control and elimination. Malaria case data for Swaziland and South Africa were obtained from their respective national Malaria Information Systems. Data for Mozambique was obtained from the Mozambican Ministry of Health. Data obtained during the course of the LSDI project was compared to the case data post the termination of the LSDI. The 12-year period of the LSDI showed a substantial decrease in disease burden amongst the three countries involved when compared to the baseline year of 2000. The decrease in malaria cases was 99 % in South Africa and 98 % in Swaziland. Malaria prevalence in Mozambique decreased by 85 % over the same period. However, after the LSDI ended, between 2012 and 2014, there was an upward trend in case data that was counter to the goal of elimination. South Africa and Swaziland benefitted from the LSDI and were able to sustain malaria control and progress to the stage of elimination. Mozambique could not sustain the gains made during the LSDI and case numbers increased. Technical and financial resources are key challenges for malaria control and elimination interventions.

Household food security impacts heavily on quality of life. We determined factors associated with food insecurity in 886 households in rural and urban Free State Province, South Africa. Significantly more urban than rural households reported current food shortage (81% and 47%, respectively). Predictors of food security included vegetable production in rural areas and keeping food for future use in urban households. Microwave oven ownership was negatively associated with food insecurity in urban households and using a primus or paraffin stove positively associated with food insecurity in rural households. Interventions to improve food availability and access should be emphasized.

Leprosy is still occurring in the Republic of South Africa, but it has been eliminated as a public health problem. The country's leprosy care and control program is being provided as a primary health-care program within the general health-care services. Maintaining health workers' leprosy knowledge and awareness at the primary health-care level is one of the program's goals. In one of the country's rural areas, the availability of good-quality leprosy poster and leaflets at primary health-care facilities has been shown to contribute significantly to maintaining health workers' leprosy knowledge and awareness.

The second Southern African Bird Atlas Project: Causes and consequences of geographical sampling bias.

PubMed

Hugo, Sanet; Altwegg, Res

2017-09-01

Using the Southern African Bird Atlas Project (SABAP2) as a case study, we examine the possible determinants of spatial bias in volunteer sampling effort and how well such biased data represent environmental gradients across the area covered by the atlas. For each province in South Africa, we used generalized linear mixed models to determine the combination of variables that explain spatial variation in sampling effort (number of visits per 5' × 5' grid cell, or "pentad"). The explanatory variables were distance to major road and exceptional birding locations or "sampling hubs," percentage cover of protected, urban, and cultivated area, and the climate variables mean annual precipitation, winter temperatures, and summer temperatures. Further, we used the climate variables and plant biomes to define subsets of pentads representing environmental zones across South Africa, Lesotho, and Swaziland. For each environmental zone, we quantified sampling intensity, and we assessed sampling completeness with species accumulation curves fitted to the asymptotic Lomolino model. Sampling effort was highest close to sampling hubs, major roads, urban areas, and protected areas. Cultivated area and the climate variables were less important. Further, environmental zones were not evenly represented by current data and the zones varied in the amount of sampling required representing the species that are present. SABAP2 volunteers' preferences in birding locations cause spatial bias in the dataset that should be taken into account when analyzing these data. Large parts of South Africa remain underrepresented, which may restrict the kind of ecological questions that may be addressed. However, sampling bias may be improved by directing volunteers toward undersampled regions while taking into account volunteer preferences.

Primary school teachers’ opinions and attitudes towards stuttering in two South African urban education districts

Background As teachers form an important part of the intervention process with children who stutter in primary school, the primary aim was to describe primary school teachers’ attitudes in South Africa. The secondary aim was to compare teachers’ attitudes towards stuttering in South Africa with those from a pooled group of respondents in the Public Opinion Survey of Human Attributes–Stuttering (POSHA-S) database from different countries collected in 2009–2014. Method A quantitative, cross-sectional survey research design was used. Primary schools in two education districts in Western Cape, South Africa, were sampled. The POSHA-S, a self-administered questionnaire, was completed by a cluster sample of 469 participants. Results Overall positive attitudes towards stuttering were found, specifically related to the potential of people who stutter, although the result should be interpreted with caution as the sample was not homogenously positive. Teachers still had misconceptions about personality stereotypes and the cause of stuttering. The attitudes of the South African sample were slightly more positive compared with the samples in the current POSHA-S database. Conclusion When developing stuttering intervention strategies, there are a number of key considerations to take into account. The study provides a basis for speech-language therapists to think about intervention with teachers and which areas of stuttering to consider.

To investigate injury-related mortality in South Africa using a nationally representative sample and compare the results with previous estimates. We conducted a retrospective descriptive study of medico-legal postmortem investigation data from mortuaries using a multistage random sample, stratified by urban and non-urban areas and mortuary size. We calculated age-specific and age-standardized mortality rates for external causes of death. Postmortem reports revealed 52,493 injury-related deaths in 2009 (95% confidence interval, CI: 46,930-58,057). Almost half (25,499) were intentionally inflicted. Age-standardized mortality rates per 100,000 population were as follows: all injuries: 109.0 (95% CI: 97.1-121.0); homicide 38.4 (95% CI: 33.8-43.0; suicide 13.4 (95% CI: 11.6-15.2) and road-traffic injury 36.1 (95% CI: 30.9-41.3). Using postmortem reports, we found more than three times as many deaths from homicide and road-traffic injury than had been recorded by vital registration for this period. The homicide rate was similar to the estimate for South Africa from a global analysis, but road-traffic and suicide rates were almost fourfold higher. This is the first nationally representative sample of injury-related mortality in South Africa. It provides more accurate estimates and cause-specific profiles that are not available from other sources.

Psychological distress amongst AIDS-orphaned children in urban South Africa.

South Africa is predicted to have 2.3 million children orphaned by Acquired Immune Deficiency Syndrome (AIDS) by 2020 (Actuarial Society of South Africa, 2005). There is little knowledge about impacts of AIDS-related bereavement on children, to aid planning of services. This study aimed to investigate psychological consequences of AIDS orphanhood in urban township areas of Cape Town, South Africa, compared to control groups of children and adolescents orphaned by other causes, and non-orphans. One thousand and twenty-five children and adolescents (aged 10-19) were interviewed using socio-demographic questionnaires and standardised scales for assessing depression, anxiety, post-traumatic stress, peer problems, delinquency and conduct problems. Controlling for socio-demographic factors such as age, gender, formal/informal dwelling and age at orphanhood, children orphaned by AIDS were more likely to report symptoms of depression, peer relationship problems, post-traumatic stress, delinquency and conduct problems than both children orphaned by other causes and non-orphaned children. Anxiety showed no differences. AIDS-orphaned children were more likely to report suicidal ideation. Compared to Western norms, AIDS-orphaned children showed higher levels of internalising problems and delinquency, but lower levels of conduct problems. Children orphaned by AIDS may be a particularly vulnerable group in terms of emotional and, to a lesser extent, behavioural problems. Intervention programs are necessary to ameliorate the psychological sequelae of losing a parent to AIDS.

The water quality of Umgeni River in KwaZulu-Natal (South Africa) was investigated from April 2011 to January 2012. Indicator bacterial populations, physico-chemical properties, heavy metal contaminants and the presence of coliphages were determined according to standard protocols. The results showed that all sampling points failed to comply with the set guidelines for turbidity, total coliform, faecal coliform and total heterotrophic counts. Salmonella spp., Shigella spp. and Vibrio cholerae were also detected in all the water samples. The somatic coliphages and F-RNA coliphages were detected more frequently in the lower reaches of the river during summer. Temperature, electrical conductivity and pH were found to have positive relationships with the microbial communities especially in the lower catchment area during spring and summer indicating the impacts of various anthropogenic activities in the surrounding areas.

Palaeobiogeographic reconstructions are underpinned by phylogenies, divergence times and ancestral area reconstructions, which together yield ancestral area chronograms that provide a basis for proposing and testing hypotheses of dispersal and vicariance. Methods for area coding include multi-state coding with a single character, binary coding with multiple characters and string coding. Ancestral reconstruction methods are divided into parsimony versus Bayesian/likelihood approaches. We compared nine methods for reconstructing ancestral areas for placental mammals. Ambiguous reconstructions were a problem for all methods. Important differences resulted from coding areas based on the geographical ranges of extant species versus the geographical provenance of the oldest fossil for each lineage. Africa and South America were reconstructed as the ancestral areas for Afrotheria and Xenarthra, respectively. Most methods reconstructed Eurasia as the ancestral area for Boreoeutheria, Euarchontoglires and Laurasiatheria. The coincidence of molecular dates for the separation of Afrotheria and Xenarthra at approximately 100 Ma with the plate tectonic sundering of Africa and South America hints at the importance of vicariance in the early history of Placentalia. Dispersal has also been important including the origins of Madagascar's endemic mammal fauna. Further studies will benefit from increased taxon sampling and the application of new ancestral area reconstruction methods. PMID:21807730

Background There have been resurgent efforts in Africa to estimate the public health impact of malaria control interventions such as insecticide treated nets (ITNs) following substantial investments in scaling-up coverage in the last five years. Little is known, however, on the effectiveness of ITN in areas of Africa that support low transmission. This hinders the accurate estimation of impact of ITN use on disease burden and its cost-effectiveness in low transmission settings. Methods and Principal Findings Using a stratified two-stage cluster sample design, four cross-sectional studies were undertaken between March-June 2007 across three livelihood groups in an area of low intensity malaria transmission in South Central Somalia. Information on bed net use; age; and sex of all participants were recorded. A finger prick blood sample was taken from participants to examine for parasitaemia. Mantel-Haenzel methods were used to measure the effect of net use on parasitaemia adjusting for livelihood; age; and sex. A total of 10,587 individuals of all ages were seen of which 10,359 provided full information. Overall net use and parasite prevalence were 12.4% and 15.7% respectively. Age-specific protective effectiveness (PE) of bed net ranged from 39% among <5 years to 72% among 5–14 years old. Overall PE of bed nets was 54% (95% confidence interval 44%–63%) after adjusting for livelihood; sex; and age. Conclusions and Significance Bed nets confer high protection against parasite infection in South Central Somalia. In such areas where baseline transmission is low, however, the absolute reductions in parasitaemia due to wide-scale net use will be relatively small raising questions on the cost-effectiveness of covering millions of people living in such settings in Africa with nets. Further understanding of the progress of disease upon infection against the cost of averting its consequent burden in low transmission areas of Africa is therefore required. PMID:18461178

Child (infant and under-5) and maternal mortality rates are key indicators for assessing the health status of populations. South Africa's maternal and child mortality rates are high, and the country mirrors the continental trend of slow progress towards its Millennium Development Goals. Rural areas are often more affected regarding child and maternal mortalities, specifically in areas with a high HIV burden. This study aims to understand the factors affecting child and maternal mortality in the Africa Centre Demographic Surveillance Area (DSA) from 2003 to 2014 towards developing tailored interventions to reduce the deaths in resource poor settings. This will be done by identifying child and maternal mortality 'hotspots' and their associated risk factors. This retrospective study will use data for 2003-2014 from the Africa Centre Demographic Information System (ACDIS) in rural KwaZulu-Natal Province, South Africa. All homesteads in the study area have been mapped to an accuracy of <2 m, all deaths recorded and the assigned cause of death established using a verbal autopsy interview. Advanced spatial-temporal clustering techniques (both regular (Kulldorff) and irregular (FleXScan)) will be used to identify mortality 'hotspots'. Various advanced statistical modelling approaches will be tested and used to identify significant risk factors for child and maternal mortality. Differences in attributability and risk factors profiles in identified 'hotspots' will be assessed to enable tailored intervention guidance/development. This multicomponent study will enable a refined intervention model to be developed for typical rural populations with a high HIV burden.

Recently, there has been a greater focus on adults with Attention-Deficit/Hyperactivity Disorder (ADHD) given that the symptoms persist in two-thirds of patients into adulthood. Areas covered: A systematic review of articles reporting on adult ADHD in SA was undertaken. From the database search, 1209 articles were identified, with 29 articles included in this analysis. Expert commentary: Fourteen of the 29 studies reviewed were exploratory, 10 were reviews/commentaries, four were developmental studies and one was a phenomenological study. More than half (58.62%) of the articles were published in local South African journals, 13.79% were published in African journals (excluding South Africa), and 27.59% of the articles were published in international journals. The impact factor for nine of the journals were not stated and the remaining 11 have impact factors ranging from 0.207 to 6.78. In 2004, only one article on adult ADHD was published in SA and by 2015, the number of publications increased to six. Adult ADHD is gaining interest in South Africa, however, there have been a limited number of studies conducted thus far. It is recommended that further studies are conducted in this new and developing field.

Hazards identified and the need for health risk assessment in the South African mining industry.

Utembe, W; Faustman, E M; Matatiele, P; Gulumian, M

2015-12-01

Although mining plays a prominent role in the economy of South Africa, it is associated with many chemical hazards. Exposure to dust from mining can lead to many pathological effects depending on mineralogical composition, size, shape and levels and duration of exposure. Mining and processing of minerals also result in occupational exposure to toxic substances such as platinum, chromium, vanadium, manganese, mercury, cyanide and diesel particulate. South Africa has set occupational exposure limits (OELs) for some hazards, but mine workers are still at a risk. Since the hazard posed by a mineral depends on its physiochemical properties, it is recommended that South Africa should not simply adopt OELs from other countries but rather set her own standards based on local toxicity studies. The limits should take into account the issue of mixtures to which workers could be exposed as well as the health status of the workers. The mining industry is also a source of contamination of the environment, due inter alia to the large areas of tailings dams and dumps left behind. Therefore, there is need to develop guidelines for safe land-uses of contaminated lands after mine closure. © The Author(s) 2015.

Various studies have underscored the relevance of community-level factors to sexual behavior and HIV/AIDS prevention efforts in Africa. However, there is a paucity of research and theorizing in this area compared to the preponderance of prevention models that focus solely on individual-level factors. Using data from the Cape Area Panel Survey and hierarchical linear models, this study examines the effects of a combination of individual-level factors and community-level poverty on sexual behaviors. Male and female respondents who perceived themselves to be at great risk of HIV infection were less likely to indulge in risky sexual behaviors. For females, race and community-level poverty were confounded such that race mediated the effects of community-level poverty. Results from this study indicate that multiple rationalities affect sexual behaviors in Cape Town, South Africa and that there is a need to consider both the social embeddedness of sexual behaviors and the rational components of decision making when designing HIV/AIDS prevention programs.

Objective In this systematic review, we estimate the prevalence of six types of arthritis in Africa; namely rheumatoid arthritis, osteoarthritis, juvenile arthritis, psoriatic arthritis, gout, and ankylosing spondylitis. Methods We comprehensively searched literature on 31 August 2014 in MEDLINE, EMBASE, Web of Science and the Cochrane Library to identify eligible studies from 1975 up to 31 July 2014. Two review authors independently selected studies, extracted data, and appraised studies. We carried out random effects meta-analysis of prevalence of arthritis and assessed heterogeneity through subgroup analyses. We performed separate analyses for population- and hospital-based studies, as well as rural and urban settings. Main Findings We included 27 cross-sectional studies (20 population-based and 7 hospital-based) from Africa reporting on the prevalence of arthritis. The majority of the studies were from South Africa (44.4%, 12/27). Rheumatoid arthritis in urban settings ranged from 0.1% in Algeria, 0.6% in the DRC, to a meta-analysis overall prevalence of 2.5% in South Africa, and in rural settings ranged from a meta-analysis overall prevalence of 0.07% in South Africa, 0.3% in Egypt, to 0.4% in Lesotho. Osteoarthritis was the most prevalent form of arthritis and in urban settings it was 55.1% in South Africa and in rural settings, all in South Africa, ranged from 29.5%, 29.7%, up to 82.7% among adults aged over 65 years. Other results include highest prevalence of 33.1% for knee osteoarthritis in rural South Africa, 0.1% for ankylosing spondylitis in rural South Africa, 4.4% for psoriatic arthritis in urban South Africa, 0.7% for gout in urban South Africa, and 0.3% for juvenile idiopathic arthritis in urban Egypt. A third of the included studies had a low risk of bias (33.3%, 9/27), 40.8% (11/27) moderate risk, and 25.9% (7/27) had a high risk of bias. Conclusions In this systematic review, we have identified the paucity of latest prevalence data on arthritis in Africa. More studies are needed to address the prevalence and the true burden of this disease in Africa. PMID:26241756

The Schurwedraai alkali granite is one of a number of prominent ultramafic-mafic and felsic intrusions in the Neoarchaean to Palaeoproterozoic sub-vertical supracrustal collar rocks of the Vredefort Dome, South Africa. The alkali granite intruded the Neoarchaean Witwatersrand Supergroup and has a peralkaline to peraluminous composition. A new zircon SHRIMP crystallization age of 2052 ± 14 Ma for the Schurwedraai alkali granite places it statistically before the Vredefort impact event at 2023 ± 4 Ma and within the accepted emplacement interval of 2050-2060 Ma of the Bushveld magmatic event. The presence of the alkali granite and associated small ultramafic-mafic intrusions in the Vredefort collar rocks extends the southern extremity of Bushveld-related intrusions to some 120 km south of Johannesburg and about 150 km south of the current outcrop area of the Bushveld Complex. The combined effect of these ultramafic-mafic and felsic bodies may have contributed to a pronouncedly steep pre-impact geothermal gradient in the Vredefort area, and to the amphibolite-grade metamorphism observed in the supracrustal collar rocks of the Vredefort Dome.

Migration in southern Africa: a comparative perspective.

PubMed

Solomon, H

1994-01-01

Population movement can be described as intra-state, East-West, South-North, and South-South. About 20 million persons globally are considered displaced, of which about 4.1 million are internally displaced persons in South Africa. East-West movement occurred for over 400 million when the Iron Curtain came down. South-North movements of asylum seekers were estimated at 442,000 in 1990. South-South movement amounted to 4 million official refugees in Africa in 1989 and 4.4 million in 1990. African has the largest concentration of refugees. This article does not address the 265,825 contract migrant workers in South Africa. South African migration is the South-South type and can be characterized as "brain-drain" of well-trained professionals in neighboring states and unskilled and illegal migrants from Mozambique and Angola. Movement is pushed or pulled according to sociocultural factors, communications and technology, geographic proximity, precedent, demographic factors, environmental factors, economic factors, and political factors. The effects of migration in South Africa include increased stress on housing, political and social tension, increased costs, overcrowding, transmission of disease, and marginalization of migrants into low status and low paid jobs. For Lesotho migrants in South Africa remittances are a major source of national wealth. South Africa has also experienced racial discord against Mozambicans and Chinese. Political right wing groups mobilize around anti-immigration platforms. Migrants can become policy tools, and many are used in wars of liberation. International attention may focus on mistreatment of refugees. Management can be construed as "carrot" or "stick" approaches. Stick approaches include forced repatriation, limiting immigration, housing in survival-level camps, public campaigns run by host countries in sending countries, or greater control of national borders. South Africa has extensively used stick approaches, which have been only partially successful. Carrot approaches rely on regional integration strategies designed to reduce wage differentials and promote global cooperation. Polycentric and ethnocentric nationalism affect management of migrants as assets or as liabilities.

Towards Zero Waste in emerging countries - A South African experience

2008-07-01

The aim of this paper is to describe the optimisation of Waste Minimisation/Zero Waste strategies into an already established integrated waste management system and to present a Zero Waste model for post-consumer waste for urban communities in South Africa. The research was undertaken towards the fulfilment of the goals of the Polokwane Declaration on Waste Management , which has set as its target the reduction of waste generation and disposal by 50% and 25%, respectively, by 2012 and the development of a plan for Zero Waste by 2022. Two communities, adjacent to the Mariannhill Landfill site in Durban, were selectedmore » as a case study for a comparative analysis of formal and informal settlements. Since the waste generated from these two communities is disposed of at the Mariannhill landfill, the impact of Zero Waste on landfill volumes could be readily assessed. A Zero Waste scheme, based on costs and landfill airspace savings, was proposed for the area. The case study demonstrates that waste minimisation schemes can be introduced into urban areas, in emerging countries, with differing levels of service and that Zero Waste models are appropriate to urban areas in South Africa.« less

Mongoose rabies in southern Africa: a re-evaluation based on molecular epidemiology.

Relative to the developed world, rabies has been poorly studied in the vast African continent. The southern African countries of Zimbabwe and South Africa, however, are known to sustain a great diversity of lyssaviruses, with large biological variations amongst genotype 1 (rabies viruses) at present more apparent here than elsewhere on the continent. One recognized biotype of rabies virus in the subcontinent appears to be specifically adapted to a variety of mongooses, belonging to the Viverrinae subfamily (family Herpestidae) and are commonly referred to as viverrid viruses, although the term mongoose rabies would be more correct, considering the taxonomic status of the host species involved. It was our objective to study the genetic relationships of 77 rabies virus isolates of this mongoose biotype, isolated in South Africa and Zimbabwe, towards elucidation of the molecular epidemiology of this interesting group of African viruses. In our study of a 592 nucleotide sequence encompassing the cytoplasmic domain of the glycoprotein and the G-L intergenic region of the viral genomes, we provide the first comprehensive data on the molecular epidemiology of these viruses and indicate a history of extended evolutionary adaptation in this geographical domain. The molecular epidemiological observations reported here are highly unlikely to be limited to the small geographical areas of South Africa and Zimbabwe and illustrate the need for lyssavirus surveillance in the rest of sub-Saharan Africa and throughout the entire continent.

South African HIV/AIDS programming overlooks migration, urban livelihoods, and informal workplaces.

Vearey, Jo; Richter, Marlise; Núñez, Lorena; Moyo, Khangelani

South Africa has the largest population of people living with HIV globally and is associated with high population mobility. The majority of migrants move in search of improved livelihood opportunities, and many who migrate (both internally and across borders) move into urban areas, often through peripheral informal settlements where HIV prevalence is shown to be double that of urban formal areas. While the relationship between migration and the spread of HIV is acknowledged as complex, the context of migration may place individuals at increased risk for acquiring HIV. Studies have demonstrated the long-wave impact of HIV and AIDS on livelihood activities and, more recently, on patterns of migration. Many migrants engage in livelihood strategies situated within the urban 'informal economy'; these informal workplaces are often overlooked in global and national legislation governing workplace responses to health and HIV and AIDS. This study draws on existing research and limited primary data to explore the implications of HIV/AIDS programming for diverse migrant groups labouring in informal workplaces in Johannesburg, South Africa. We describe three case studies: waste-pickers at a dumpsite in a peripheral urban informal settlement; barmen and cleaners working in inner-city hotels where sex is also sold; and, migrants engaged in informal livelihood activities who are also members of burial societies. Given the importance of varied informal livelihood activities for diverse migrant groups, particularly in urban areas of South Africa, we propose that the national HIV/AIDS response can and should engage with internal and cross-border migrants in informal workplaces - which is in line with the principle of universal access and will strengthen the national response. Especially, we point out the potential for burial societies to provide an entry point for HIV/AIDS programming that targets migrant groups involved in the informal economy of South African cities.

Applying a framework for assessing the health system challenges to scaling up mHealth in South Africa

PubMed Central

2012-01-01

Background Mobile phone technology has demonstrated the potential to improve health service delivery, but there is little guidance to inform decisions about acquiring and implementing mHealth technology at scale in health systems. Using the case of community-based health services (CBS) in South Africa, we apply a framework to appraise the opportunities and challenges to effective implementation of mHealth at scale in health systems. Methods A qualitative study reviewed the benefits and challenges of mHealth in community-based services in South Africa, through a combination of key informant interviews, site visits to local projects and document reviews. Using a framework adapted from three approaches to reviewing sustainable information and communication technology (ICT), the lessons from local experience and elsewhere formed the basis of a wider consideration of scale up challenges in South Africa. Results Four key system dimensions were identified and assessed: government stewardship and the organisational, technological and financial systems. In South Africa, the opportunities for successful implementation of mHealth include the high prevalence of mobile phones, a supportive policy environment for eHealth, successful use of mHealth for CBS in a number of projects and a well-developed ICT industry. However there are weaknesses in other key health systems areas such as organisational culture and capacity for using health information for management, and the poor availability and use of ICT in primary health care. The technological challenges include the complexity of ensuring interoperability and integration of information systems and securing privacy of information. Finally, there are the challenges of sustainable financing required for large scale use of mobile phone technology in resource limited settings. Conclusion Against a background of a health system with a weak ICT environment and limited implementation capacity, it remains uncertain that the potential benefits of mHealth for CBS would be retained with immediate large-scale implementation. Applying a health systems framework facilitated a systematic appraisal of potential challenges to scaling up mHealth for CBS in South Africa and may be useful for policy and practice decision-making in other low- and middle-income settings.

Producing electricity from wind is attractive because it provides a clean, low-maintenance power supply. However, wind resource is intermittent on various timescales, thus occasionally introducing large and sudden changes in power supply. A better understanding of this variability can greatly benefit power grid planning. In the following study, wind resource is characterized using metrics that highlight these intermittency issues; therefore identifying areas of high and low wind power reliability in southern Africa and Kenya at different time-scales. After developing a wind speed profile, these metrics are applied at various heights in order to assess the added benefit of raising themore » wind turbine hub. Furthermore, since the interconnection of wind farms can aid in reducing the overall intermittency, the value of interconnecting near-by sites is mapped using two distinct methods. Of the countries in this region, the Republic of South Africa has shown the most interest in wind power investment. For this reason, we focus parts of the study on wind reliability in the country. The study finds that, although mean Wind Power Density is high in South Africa compared to its neighboring countries, wind power resource tends to be less reliable than in other parts of southern Africa—namely central Tanzania. We also find that South Africa’s potential varies over different timescales, with higher reliability in the summer than winter, and higher reliability during the day than at night.

Water market transfers in South Africa: Two case studies

NASA Astrophysics Data System (ADS)

Nieuwoudt, W. L.; Armitage, R. M.

2004-09-01

Statistical analyses (discriminant, logit, and principal components) of water transfers in the Lower Orange River showed that water rights were transferred to farmers with the highest return per unit of water applied, those producing table grapes, and with high-potential arable "outer land" without water rights. Only unused water (sleeper right) was transferred, while water saved (through adoption of conservation practices) was retained possibly for security purposes. A second study in the Nkwaleni Valley in northern KwaZulu-Natal found that no water market had emerged despite the scarcity of water in the area. No willing sellers of water rights existed. Demand for institutional change to establish tradable water rights may take more time in the second area since crop profitability in this area is similar for potential buyers and nonbuyers. Transaction costs appear larger than benefits from market transactions. Farmers generally use all their water rights in the second area and retain surplus water rights as security against drought because of unreliable river flow. This study indicates that these irrigation farmers are highly risk averse (downside risk). Government policies that increase the level of risk and reduce security of licenses are estimated to have a significant effect on future investment in irrigation. In an investment model the following variables explain future investment: expected profits, liquidity, risk aversion (Arrow-Pratt), and security of water use rights. The study is seen in the light of the New South African Water Act of 1998. According to this act, the ownership of water in South Africa has changed from private to public. This reform may not impede the development of water markets in South Africa since in the well-developed water markets of the United States, western states claim ownership of water within their boundaries. All states in the western United States allow private rights in the use of water to be established and sold.

Legacy, legitimacy, and possibility: an exploration of community health worker experience across the generations in Khayelitsha, South Africa.

PubMed

Swartz, Alison

2013-06-01

In South Africa, the response to HIV and TB epidemics is complex, varied, and contextually defined. "Task-shifting" and a movement toward a decentralized model of care have led to an increased reliance on community health workers (CHWs) providing health care services to residents of impoverished, peri-urban areas. Public health policy tends to present CHWs as a homogeneous group, with little attention paid to the nuances of experience, motivation, and understanding, which distinguish these care workers from one another and from other kinds of health workers. An exploration of the layered meanings of providing community health care services under financially, politically, and socially difficult conditions reveals clear distinctions of experience across the generations. Many older CHWs say that ubuntu, a notion of shared African humanity, is being "killed off" by the younger generation, whereas younger CHWs often describe older women as being "jealous" of the opportunities that this younger generation has for education, training, and employment. The structure of the South African health system, past and present responses to disease epidemics, and the legacy of apartheid's structural violence have amplified these generational differences among CHWs. Using ethnographic data collected from approximately 20 CHWS in a peri-urban settlement in Cape Town, South Africa, I explore how CHWs experience and understand legitimacy in the moral economy of care. A call for closer attention to the experiences of CHWs is critical when designing public health policies for the delivery of health care services in impoverished communities in South Africa. © 2013 by the American Anthropological Association.

'Pharmacists have been left out of the loop': exploring the role of pharmacists in the management of HIV/AIDS in South Africa.

PubMed

Gilbert, Leah

2016-02-01

The aim of this paper is to portray and critically analyse the role played by pharmacists in the management of the HIV/AIDS epidemic in South Africa. The data used for this article originate in secondary and primary sources. They were collected by means of a documentary analysis of all relevant documents of significance as well as exploratory telephone interviews conducted with a systematic random sample of community pharmacies in Greater Johannesburg in 2004 and 2010. It is clear from the original strategic framework that the government envisaged pharmacists playing a significant role in the various facets of the epidemic. Following these intentions, the South African Pharmacy Council and the Pharmaceutical Society of South Africa embarked on a process of establishing AIDS Resource Centres in pharmacies. However, although in some areas pharmacists are contributing to the management of HIV/AIDS, the overall scenario revealed is that of lack of willingness to go for additional training and/or to invest in restructuring the pharmacy to 'accommodate' the activities of an 'AIDS Resource Centre' without the prospects of adequate financial gains. In a parallel process, the original, more meaningful role for pharmacists in the management of HIV/AIDS has not been featured in recent professional and governmental documentation. The reality on the ground is that of a missed opportunity as the pharmacists have not risen to the challenge and they remain on the margins, and not at the centre, of those professionals managing HIV/AIDS in South Africa. © 2015 Royal Pharmaceutical Society.

Dini, Leigh; Frean, John

2003-01-01

To assess the quality of malaria diagnosis in 115 South African laboratories participating in the National Health Laboratory Service Parasitology External Quality Assessment Programme we reviewed the results from 7 surveys from January 2000 to August 2002. The mean percentage incorrect result rate was 13.8% (95% CI 11.3-16.9%), which is alarmingly high, with about 1 in 7 blood films being incorrectly interpreted. Most participants with incorrect blood film interpretations had acceptable Giemsa staining quality, indicating that there is less of a problem with staining technique than with blood film interpretation. Laboratories in provinces in which malaria is endemic did not necessarily perform better than those in non-endemic areas. The results clearly suggest that malaria laboratory diagnosis throughout South Africa needs strengthening by improving laboratory standardization and auditing, training, quality assurance and referral resources.

The Afrikaner is an indigenous South African breed of "Sanga" type beef cattle along with breeds such as the Drakensberger and Nguni. Six composite breeds have been developed from crosses with the Afrikaner. Additionally, Afrikaner has been the base from which exotic breeds were established in South Africa through backcrossing. The study examined genetic diversity of Afrikaner cattle by genotyping 1257 animals from 27 herds in different geographic areas of South Africa and Namibia using 11 microsatellite markers. Multiple-locus assignment, performed using the Bayesian clustering algorithm of STRUCTURE, revealed three underlying genotypic groups. These groups were not geographically localized. Across herds and markers, the proportion of unbiased heterozygosity ranged from 0.49 to 0.72 averaging 0.57; mean number of alleles per locus ranged from 3.18 to 7.09, averaging 4.81; and allelic richness ranged from 2.35 to 3.38, averaging 2.67. It is concluded that a low inbreeding level of 2.7% and a moderate to high degree of variation still persists within the Afrikaner cattle breed, despite the recent decline in numbers of animals.

Assessment of Internet-based tele-medicine in Africa (the RAFT project).

2006-01-01

The objectives of this paper on the Réseau Afrique Francophone de Télémédecine (RAFT) project are the evaluation of feasibility, potential, problems and risks of an Internet-based tele-medicine network in developing countries of Africa. The RAFT project was started in Western African countries 5 years ago and has now extended to other regions of Africa as well (i.e. Madagascar, Rwanda). A project for the development of a national tele-medicine network in Mali was initiated in 2001, extended to Mauritania in 2002 and to Morocco in 2003. By 2006, a total of nine countries are connected. The entire technical infrastructure is based on Internet technologies for medical distance learning and tele-consultations. The results are a tele-medicine network that has been in productive use for over 5 years and has enabled various collaboration channels, including North-to-South (from Europe to Africa), South-to-South (within Africa), and South-to-North (from Africa to Europe) distance learning and tele-consultations, plus many personal exchanges between the participating hospitals and Universities. It has also unveiled a set of potential problems: (a) the limited importance of North-to-South collaborations when there are major differences in the available resources or the socio-cultural contexts between the collaborating parties; (b) the risk of an induced digital divide if the periphery of the health system in developing countries is not involved in the development of the network; and (c) the need for the development of local medical content management skills. Particularly point (c) is improved through the collaboration between the various countries as professionals from the medical and the computer science field are sharing courses and resources. Personal exchanges between partners in the project are frequent, and several persons received an education at one of the partner Universities. As conclusion, we can say that the identified risks have to be taken into account when designing large-scale tele-medicine projects in developing countries. These problems can be mitigated by fostering South-South collaboration channels, by the use of satellite-based Internet connectivity in remote areas, the appreciation of local knowledge and its publication on-line. The availability of such an infrastructure also facilitates the development of other projects, courses, and local content creation.

Obesity and other noncommunicable disease (NCD) risk factors are increasing in low- and middle-income countries. There are few data on the association between increased added sugar intake and NCD risk in these countries. We assessed the relation between added sugar intake and NCD risk factors in an African cohort study. Added sugars were defined as all monosaccharides and disaccharides added to foods and beverages during processing, cooking, and at the table. We conducted a 5-y follow-up of a cohort of 2010 urban and rural men and women aged 30-70 y of age at recruitment in 2005 from the North West Province in South Africa. Added sugar intake, particularly in rural areas, has increased rapidly in the past 5 y. In rural areas, the proportion of adults who consumed sucrose-sweetened beverages approximately doubled (for men, from 25% to 56%; for women, from 33% to 63%) in the past 5 y. After adjustment, subjects who consumed more added sugars (≥10% energy from added sugars) compared with those who consumed less added sugars had a higher waist circumference [mean difference (95% CI): 1.07 cm (0.35, 1.79 cm)] and body mass index (in kg/m²) [0.43 (0.12, 0.74)] and lower HDL cholesterol [-0.08 mmol/L (-0.14, 0.002 mmol/L)]. This cohort showed dramatic increases in added sugars and sucrose-sweetened beverage consumption in both urban and rural areas. Increased consumption was associated with increased NCD risk factors. In addition, the study showed that the nutrition transition has reached a remote rural area in South Africa. Urgent action is needed to address these trends. © 2014 American Society for Nutrition.

Double standards: the multinational asbestos industry and asbestos-related disease in South Africa.

PubMed

McCulloch, Jock; Tweedale, Geoffrey

2004-01-01

This study documents and contrasts the development of knowledge about asbestos-related disease (ARD) in South Africa and the United Kingdom. It also contributes to the globalization debate by exploring corporate decision-making in a multinational industry. Between the 1930s and 1960s, the leading U.K. asbestos companies developed a sophisticated knowledge of ARD, though in South Africa, where the leading companies such as Turner & Newall and Cape Asbestos owned mines, there was little attempt to apply this knowledge. Asbestos mines (and their environments) in South Africa were uniquely dusty and ARD was rife. Social and political factors in South Africa, especially apartheid, allowed these companies to apply double standards, even after 1960 when the much more serious hazard of mesothelioma was identified. This shows the need for greater regulation of multinationals. Because of the lack of such regulation in the early 1960s, an opportunity was lost to prevent the current high morbidity and mortality of ARD both in South Africa and worldwide.

The author has identified the following significant results. It has been shown that ERTS imagery, particularly in the form of 1:500,000 scale false color photolithographic prints, can contribute very significantly towards facilitating and accelerating (dramatically, in the case of vegetation) resource surveys and geologic mapping. Fire mapping on a national scale becomes a feasibility, numerous new geologic features, particularly lineaments, have been discovered, land use can be mapped efficiently on a regional scale and degraded areas identified. The first detailed tectonic and geomorphological maps of the Republic of South Africa will be published in the near future mainly owing to the availability of ERTS-1 imagery.

Lack of access to nutritious and balanced diets remains a major impediment to the health and well-being of people living in rural areas. The study utilizes a qualitative systematic approach to conduct an environmental scan and review of scientific literature of studies conducted in South Africa, specifically KwaZulu-Natal (KZN). Availability and access to nutritious, diverse and balanced diets were identified as key constraints for achieving food and nutrition security as well as for human health and well-being. This has led to both under- and over-nutrition, with the former, in particular stunting, affecting children under 5 years. A high incidence of over-nutrition, both overweight and obesity, was observed among black African females. In South Africa, poor people rely mostly on social grants and cannot afford a balanced diet. Under these circumstances, agriculture could be used to increase availability and access to diverse and nutritious foods for the attainment of a balanced diet. The wider use of traditional vegetable crops and pulses could improve availability and access to healthy and locally available alternatives. The promotion of household and community food gardens, and the use of nutrient dense crops with low levels of water use, i.e., high nutritional water productivity, offers prospects for addressing malnutrition in poor rural areas.

A framework for recognition of prior learning within a Postgraduate Diploma of Nursing Management in South Africa.

PubMed

Jooste, Karien; Jasper, Melanie

2010-09-01

The present study focuses on the development of an initial framework to guide educators in nursing management in designing a portfolio for the recognition of prior learning for accreditation of competencies within a postgraduate diploma in South Africa. In South Africa, there is a unique educational need, arising from the legacy of apartheid and previous political regimes, to facilitate educational development in groups previously unable to access higher education. Awareness of the need for continuous professional development in nursing management practice and recognition of prior learning in the educational environment has presented the possibility of using one means to accomplish both aims. Although the content of the present study is pertinent to staff development of nurse managers, it is primarily written for nurse educators in the field of nursing management. The findings identify focus areas to be addressed in a recognition of prior learning portfolio to comply with the programme specific outcomes of Nursing Service Management. Further work to refine these focus areas to criteria that specify the level of performance required to demonstrate achievement is needed. CONCLUSION AND IMPLICATIONS FOR NURSE MANAGERS: Managers need to facilitate continuous professional development through portfolio compilation which acknowledges the learning opportunities within the workplace and can be used as recognition of prior learning. © 2010 The Authors.

Fires in South Africa, snow in Lesotho

NASA Technical Reports Server (NTRS)

2002-01-01

The precipitation that brought snow fall to the Drakensberg Mountains in Lesotho in southern Africa was not enough to quench the numerous fires (marked with red dots) burning throughout the Republic of South Africa. These Moderate Resolution Imaging Spectroradiometer (MODIS) images from June 18, 2002, and July 2, 2002, show the snowfall in landlocked Lesotho contrasting sharply with the country's brown, mountainous terrain. (In the false-color image, vegetation is bright green, bare soil is brown, and burned areas are reddish-brown. In northeast Republic of South Africa, right along the border with Mozambique, the smooth, gray-brown terrain shows the boundaries of Kruger National Park. The Park was established in the late 1800s to protect game species, such as elephants, antelope, and bison, which were being hunted in great numbers. In this image, dark brown patches reveal the location of previous fires. The vegetation has yet to come back, and the landscape is virtually bare. NASA scientists study fire behavior in Kruger as part of the SAFARI field campaign. Running southward through Mozambique and into the Indian Ocean is the muddy Limpopo River--known to many through Rudyard Kipling's 'Just-so' story about how the elephant got its trunk.

South Africa's protracted struggle for equal distribution and equitable access - still not there.

PubMed

van Rensburg, Hendrik C J

2014-05-08

The purpose of this contribution is to analyse and explain the South African HRH case, its historical evolution, and post-apartheid reform initiatives aimed at addressing deficiencies and shortfalls. HRH in South Africa not only mirrors the nature and diversity of challenges globally, but also the strategies pursued by countries to address these challenges. Although South Africa has strongly developed health professions, large numbers of professional and mid-level workers, and also well-established training institutions, it is experiencing serious workforce shortages and access constraints. This results from the unequal distribution of health workers between the well-resourced private sector over the poorly-resourced public sector, as well as from distributional disparities between urban and rural areas. During colonial and apartheid times, disparities were aggravated by policies of racial segregation and exclusion, remnants of which are today still visible in health-professional backlogs, unequal provincial HRH distribution, and differential access to health services for specific race and class groups. Since 1994, South Africa's transition to democracy deeply transformed the health system, health professions and HRH establishments. The introduction of free-health policies, the district health system and the prioritisation of PHC ensured more equal distribution of the workforce, as well as greater access to services for deprived groups. However, the HIV/AIDS epidemic brought about huge demands for care and massive patient loads in the public-sector. The emigration of health professionals to developed countries and to the private sector also undermines the strength and effectiveness of the public health sector. For the poor, access to care thus remains constrained and in perpetual shortfall. The post-1994 government has introduced several HRH-specific strategies to recruit, distribute, motivate and retain health professionals to strengthen the public sector and to expand access and coverage. Of great significance among these is the NHI Plan that aims to bridge the structural divide and to redistribute material and human resources more equally. Its success largely hinges on HRH and the balanced deployment of the national workforce.Low- and middle-income countries have much to learn from South African HRH experiences. In turn, South Africa has much to learn from other countries, as this case study shows.

to evaluate the feasibility, potential and risks of an internet-based telemedicine network in developing countries of Western Africa. a project for the development of a national telemedicine network in Mali was initiated in 2001, using internet-based technologies for distance learning and teleconsultations. the telemedicine network has been in productive use for 12 months and has enabled various collaboration channels, including North-South, South-South, and South-North distance learning and teleconsultations. It also unveiled a set of potential problems: a) limited pertinence of North-South collaborations when there are major differences in available resources or socio-cultural contexts between the collaborating parties; b) risk of induced digital divide if the periphery of the health system is not involved in the development of the network, and c) need for the development of local medical contents management skills. the identified risks must be taken into account when designing large-scale telemedicine projects in developing countries and can be mitigated by the fostering of South-South collaboration channels, the use of satellite-based internet connectivity in remote areas, and the valorization of local knowledge and its publication on-line.

First results from a full-waveform inversion of the African continent using Salvus

NASA Astrophysics Data System (ADS)

van Herwaarden, D. P.; Afanasiev, M.; Krischer, L.; Trampert, J.; Fichtner, A.

2017-12-01

We present the initial results from an elastic full-waveform inversion (FWI) of the African continent which is melded together within the framework of the Collaborative Seismic Earth Model (CSEM) project. The continent of Africa is one of the most geophysically interesting regions on the planet. More specifically, Africa contains the Afar Depression, which is the only place on Earth where incipient seafloor spreading is sub-aerially exposed, along with other anomalous features such as the topography in the south, and several smaller surface expressions such as the Cameroon Volcanic Line and Congo Basin. Despite its significance, relatively few tomographic images exist of Africa, and, as a result, the debate on the geophysical origins of Africa's anomalies is rich and ongoing. Tomographic images of Africa present unique challenges due to uneven station coverage: while tectonically active areas such as the Afar rift are well sampled, much of the continent exhibits a severe lack of seismic stations. And, while Africa is mostly surrounded by tectonically active spreading plate boundaries, the interior of the continent is seismically quiet. To mitigate such issues, our simulation domain is extended to include earthquakes occurring in the South Atlantic and along the western edge of South America. Waveform modelling and inversion is performed using Salvus, a flexible and high-performance software suite based on the spectral-element method. Recently acquired recordings from the AfricaArray and NARS seismic networks are used to complement data obtained from global networks. We hope that this new model presents a fresh high-resolution image of African geodynamic structure, and helps advance the debate regarding the causative mechanisms of its surface anomalies.

Background Obesity is a major risk factor for emerging non-communicable diseases (NCDS) in middle income countries including South Africa (SA). Understanding the multiple and complex determinants of obesity and their true population attributable impact is critical for informing and developing effective prevention efforts using scientific based evidence. This study identified contextualised high impact factors associated with obesity in South Africa. Methods Analysis of three national cross sectional (repeated panel) surveys, using a multilevel logistic regression and population attributable fraction estimation allowed for identification of contextualised high impact factors associated with obesity (BMI>30 kg/m2) among adults (15years+). Results Obesity prevalence increased significantly from 23.5% in 2008 to 27.2% in 2012, with a significantly (p-value<0.001) higher prevalence among females (37.9% in 2012) compared to males (13.3% in 2012). Living in formal urban areas, white ethnicity, being married, not exercising and/or in higher socio-economic category were significantly associated with male obesity. Females living in formal or informal urban areas, higher crime areas, African/White ethnicity, married, not exercising, in a higher socio-economic category and/or living in households with proportionate higher spending on food (and unhealthy food options) were significantly more likely to be obese. The identified determinants appeared to account for 75% and 43% of male and female obesity respectively. White males had the highest relative gain in obesity from 2008 to 2012. Conclusions The rising prevalence of obesity in South Africa is significant and over the past 5 years the rising prevalence of Type-2 diabetes has mirrored this pattern, especially among females. Targeting young adolescent girls should be a priority. Addressing determinants of obesity will involve a multifaceted strategy and requires at individual and population levels. With rising costs in the private and public sector to combat obesity related NCDS, this analysis can inform culturally sensitive mass communications and wellness campaigns. Knowledge of social determinants is critical to develop “best buys”. PMID:26061419

Background High early mortality in patients with HIV-1 starting antiretroviral therapy (ART) in sub-Saharan Africa, compared to Europe and North America, is well documented. Longer-term comparisons between settings have been limited by poor ascertainment of mortality in high burden African settings. This study aimed to compare mortality up to four years on ART between South Africa, Europe, and North America. Methods and Findings Data from four South African cohorts in which patients lost to follow-up (LTF) could be linked to the national population register to determine vital status were combined with data from Europe and North America. Cumulative mortality, crude and adjusted (for characteristics at ART initiation) mortality rate ratios (relative to South Africa), and predicted mortality rates were described by region at 0–3, 3–6, 6–12, 12–24, and 24–48 months on ART for the period 2001–2010. Of the adults included (30,467 [South Africa], 29,727 [Europe], and 7,160 [North America]), 20,306 (67%), 9,961 (34%), and 824 (12%) were women. Patients began treatment with markedly more advanced disease in South Africa (median CD4 count 102, 213, and 172 cells/µl in South Africa, Europe, and North America, respectively). High early mortality after starting ART in South Africa occurred mainly in patients starting ART with CD4 count <50 cells/µl. Cumulative mortality at 4 years was 16.6%, 4.7%, and 15.3% in South Africa, Europe, and North America, respectively. Mortality was initially much lower in Europe and North America than South Africa, but the differences were reduced or reversed (North America) at longer durations on ART (adjusted rate ratios 0.46, 95% CI 0.37–0.58, and 1.62, 95% CI 1.27–2.05 between 24 and 48 months on ART comparing Europe and North America to South Africa). While bias due to under-ascertainment of mortality was minimised through death registry linkage, residual bias could still be present due to differing approaches to and frequency of linkage. Conclusions After accounting for under-ascertainment of mortality, with increasing duration on ART, the mortality rate on HIV treatment in South Africa declines to levels comparable to or below those described in participating North American cohorts, while substantially narrowing the differential with the European cohorts.

Abstract Objective To investigate injury-related mortality in South Africa using a nationally representative sample and compare the results with previous estimates. Methods We conducted a retrospective descriptive study of medico-legal postmortem investigation data from mortuaries using a multistage random sample, stratified by urban and non-urban areas and mortuary size. We calculated age-specific and age-standardized mortality rates for external causes of death. Findings Postmortem reports revealed 52 493 injury-related deaths in 2009 (95% confidence interval, CI: 46 930–58 057). Almost half (25 499) were intentionally inflicted. Age-standardized mortality rates per 100 000 population were as follows: all injuries: 109.0 (95% CI: 97.1–121.0); homicide 38.4 (95% CI: 33.8–43.0; suicide 13.4 (95% CI: 11.6–15.2) and road-traffic injury 36.1 (95% CI: 30.9–41.3). Using postmortem reports, we found more than three times as many deaths from homicide and road-traffic injury than had been recorded by vital registration for this period. The homicide rate was similar to the estimate for South Africa from a global analysis, but road-traffic and suicide rates were almost fourfold higher. Conclusion This is the first nationally representative sample of injury-related mortality in South Africa. It provides more accurate estimates and cause-specific profiles that are not available from other sources. PMID:26229201

Exploring repeat HIV testing among men who have sex with men in Cape Town and Port Elizabeth, South Africa.

Despite the high prevalence of HIV among men who have sex with men (MSM) - and the general adult population - in South Africa, there is little data regarding the extent to which MSM seek repeat testing for HIV. This study explores reported histories of HIV testing, and the rationales for test seeking, among a purposive sample of 34 MSM in two urban areas of South Africa. MSM participated in activity-based in-depth interviews that included a timeline element to facilitate discussion. Repeat HIV testing was limited among participants, with three-quarters having two or fewer lifetime HIV tests, and over one-third of the sample having one or fewer lifetime tests. For most repeat testers, the time gap between their HIV tests was greater than the one-year interval recommended by national guidelines. Analysis of the reasons for seeking HIV testing revealed several types of rationale. The reasons for a first HIV test were frequently one-time occurrences, such as a requirement prior to circumcision, or motivations likely satisfied by a single HIV test. For MSM who reported repeat testing at more timely intervals, the most common rationale was seeking test results with a sex partner. Results indicate a need to shift HIV test promotion messaging and programming for MSM in South Africa away from a one-off model to one that frames HIV testing as a repeated, routine health maintenance behavior.

Hotspots and Superswell Beneath Africa Inferred From Surface Wave Anisotropic Tomography.

NASA Astrophysics Data System (ADS)

Sebai, A.; Stutzmann, E.; Montagner, J.

2003-12-01

In order to study the interaction at depth between hotspots and lithosphere we present a new anisotropic S-wave tomographic model of Africa which is derived from Rayleigh and Love wave phase velocity measurements. The strongest negative anomaly corresponds to the Afar plume which is presently the most active area of Africa. This slow anomaly, visible down to the deepest inverted depth (400km), is associated with azimuthal anisotropy that is weak right beneath the Afar and whose direction at further distances is diverging around the plume. This is consistent with active upwelling beneath the Afar. The smaller hotspots of Tibesti, Darfur, Hoggar and Mt Cameroon have appeared in regions that had been weakened by Late Jurassic-Early Cretaceous (145 Ma) rifting of West and Central Africa. They are associated with slow velocities down to about 200km. The smaller amplitude of these anomalies with respect to the Afar area and their limited depth extent may indicate that these hotspots have their origin in the uppermost boundary layer between asthenosphere and lithosphere. Nevertheless, there may be a complex relationship at depths shallower than 150km between these hotspots and the Afar. The superswell, located in the southern part of Africa is characterized by a broad area of positive velocity anomaly visible down to 300km depth. The base of Kalahari craton ( ˜ 280 km) is evidently characterized by an increase of azimuthal anisotropy. The direction of azimuthal axis is roughly North-South that rotates at the longitude of the Eastern rift to move around the Afar. This may suggest a feeding of Victoria and Afar hotspots from the deep South African superplume.

Public health implications of changing patterns of recruitment into the South African mining industry, 1973-2012: a database analysis.

The triple epidemic of silicosis, tuberculosis and HIV infection among migrant miners from South Africa and neighbouring countries who have worked in the South African mining industry is currently the target of regional and international control efforts. These initiatives are hampered by a lack of information on this population. This study analysed the major South African mining recruitment database for the period 1973 to 2012 by calendar intervals and demographic and occupational characteristics. Changes in area of recruitment were mapped using a geographic information system. The database contained over 10 million contracts, reducible to 1.64 million individuals. Major trends relevant to health projection were a decline in gold mining employment, the major source of silicosis; increasing recruitment of female miners; and shifts in recruitment from foreign to South African miners, from the Eastern to the Northwestern parts of South Africa, and from company employees to contractors. These changes portend further externalisation of the burden of mining lung disease to home communities, as miners, particularly from the gold sector, leave the industry. The implications for health, surveillance and health services of the growing number of miners hired as contractors need further research, as does the health experience of female miners. Overall, the information in this report can be used for projection of disease burden and direction of compensation, screening and treatment services for the ex-miner population throughout Southern Africa.

Magnetotelluric measurements across the southern Barberton greenstone belt, South Africa: data improving strategies and 2-D inversion results

NASA Astrophysics Data System (ADS)

Kutter, S.; Chen, X.; Weckmann, U.

2011-12-01

Magnetotelluric (MT) measurements in areas with electromagnetic (EM) noise sources such as electric fences, power and railway lines pose severe challenges to the standard processing procedures. In order to significantly improve the data quality advanced filtering and processing techniques need to be applied. The presented 5-component MT data set from two field campaigns in 2009 and 2010 in the Barberton/Badplaas area, South Africa, was acquired within the framework of the German-South African geo-scientific research initiative Inkaba yeAfrica. Approximately 200 MT sites aligned along six profiles provide a good areal coverage of the southern part of the Barberton Greenstone Belt (BGB). Since it is one of the few remaining well-preserved geological formations from the Archean, it presents an ideal area to study the tectonic evolution and the role of plate tectonics on Early Earth. Comparing the electric properties, the surrounding high and low grade metamorphic rocks are characteristically resistive whereas mineralized shear zones are possible areas of higher electrical conductivity. Mapping their depth extension is a crucial step towards understanding the formation and the evolution of the BGB. Unfortunately, in the measurement area numerous noise sources were active, producing severe spikes and steps in the EM fields. These disturbances mainly affect long periods which are needed for resolving the deepest structures. The Remote Reference technique as well as two filtering techniques are applied to improve the data in different period ranges. Adjusting their parameters for each site is necessary to obtain the best possible results. The improved data set is used for two-dimensional inversion studies for the six profiles applying the RLM2DI algorithm by Rodi and Mackie (2001, implemented in WinGlink). In the models, areas with higher conductivity can be traced beneath known faults throughout the entire array along different profiles. Resistive zones seem to correlate well with plutonic intrusions.

We describe a new species, Calvadosia lewisi, from South Africa and review the staurozoan fauna of the region. Three other species are previously known from South Africa: Calvadosia capensis (Carlgren, 1938); Depastromorpha africana Carlgren, 1935; and Lipkea stephensoni Carlgren, 1933, but all of these are known from very few records and have been poorly illustrated and documented to date. We provide brief descriptions and photographic illustrations for each species and a list of local and global geographical records. Two (L. stephensoni and C. lewisi), but possibly three (D. africana), of the four known South African staurozoan species are endemic from South Africa. The new species, images, and extra distributional records presented here greatly improve knowledge of the staurozoan fauna in South Africa and, consequently, of the Southern Hemisphere.

This SeaWiFS true-color image acquired over Southern Africa on Sept. 4, 2000, shows a thick shroud of smoke and haze blanketing much of the southern half of the continent. The smoke in this scene is being generated by a tremendous number of fires burning over a large area across the countries of Angola, Zambia, Mozambique, Zimbabwe, Botswana, and the Northern Province of South Africa. In this image, the smoke (grey pixels) is easily distinguished from clouds (bright white pixels). Refer to the Images and Data section for a larger scale view of the fires in Southern Africa. Data from both the SeaWiFS and Terra satellites are being used by an international team of scientists participating in the SAFARI field experiment. The objective of SAFARI is to measure the effects of windblown smoke and dust on air quality and the Earth's radiant energy budget. This image was produced using SeaWiFS channels 6, 5, and 1 (centered at 670 nm, 555 nm , and 412 nm, respectively).

African tick-bite fever (ATBF), a tickborne disease endemic in rural areas of sub-Saharan Africa and the West Indies caused by Rickettsia africae, has been recognized as an emerging health problem in recent years. ATBF has been reported as the second most commonly documented etiology of fever, after malaria, in travelers who return ill from sub-Saharan Africa. Most cases reported in the literature occurred in middle-aged adults, so the incidence of ATBF in children is unclear. We report a cluster of three cases of ATBF that occurred in children ages 7 to 16 years after returning from a game-hunting safari in South Africa. © 2017 Wiley Periodicals, Inc.

Turning dread into capital: South Africa's AIDS diplomacy.

PubMed

Fourie, Pieter

2013-03-05

In much of the world, President George W. Bush was not admired for his foreign policy and diplomacy. It is therefore ironic that Bush's single most uncontested foreign policy triumph was an instance of what has now become known as "health diplomacy". In 2003 Bush launched the President's Emergency Plan for AIDS Relief, a five-year $15 billion initiative to fight HIV/AIDS, mostly in Africa. The president's pragmatic health diplomacy may well save his foreign policy legacy. This article argues that a middle power such as South Africa should consider a similar instrumental AIDS diplomatic strategy, to rehabilitate its public health as well as foreign policy images. This article reflects on the emergence and contemporary practice of health diplomacy. In particular, it explores the potential of niche areas within health diplomacy to become constructive focal points of emerging middle powers' foreign policies. Middle powers often apply niche diplomacy to maximise their foreign policy impact, particularly by pursuing a multilateral agenda. The literature on middle powers indicates that such foreign policy ambitions and concomitant diplomacy mostly act to affirm the global status quo. Instead, this paper argues that there may well be niches within health diplomacy in particular that can be used to actually challenge the existing global order. Emerging middle powers in particular can use niche areas within health diplomacy in a critical theoretical manner, so that foreign policy and diplomacy become a project of emancipation and transformation, rather than an affirmation of the world as it is. The article first describes the emergence and contemporary practice of health diplomacy; this is followed by a discussion of niche diplomacy, in particular as it applies to the foreign policy agendas of emerging middle powers. It then reviews South African foreign policy and diplomacy, before situating these policies within the context of emerging mechanisms of south-south multilateralism. The article concludes by synthesizing these elements and advocating for a South African AIDS diplomacy, emphasizing its potential to galvanize a global project of emancipation.

Impediments to the adoption of alternative sewerage in South African urban informal settlements.

PubMed

Ashipala, N; Armitage, N P

2011-01-01

In recent decades South Africa has witnessed a substantial growth in its urban population. This growth has been accompanied by the mushrooming of informal settlements (shantytowns) flanking more formal development. The lack of adequate urban drainage in many of these informal settlements has resulted in extremely polluted environments which add to the disease burden of the poor people who live there. In many instances, informal settlements in South Africa are established on marginal land that is inherently difficult to service using conventional gravity sewerage. International experience has shown that various alternative wastewater collection systems may present more appropriate ways of providing water-borne sewerage in areas that are difficult to service by conventional means. Alternative sewerage schemes have however had a poor record of success in South African informal settlements - primarily stemming from the implementing agencies' failure to adequately address various social and institutional factors. In this paper, a review of South African experiences with simplified sewerage, settled sewerage and vacuum sewerage in urban informal settlements is used to highlight the key constraints that currently impede the application of these technologies.

Scaphitid ammonites are described and illustrated from the Upper Cretaceous of the coastal region of north-eastern South Africa. Scaphites kieslingswaldensis Langenhan and Grundey, 1891, Scaphites manasoaensis Collignon, 1965, and Yezoites concinna sp. nov. occur in the Coniacian part of the St Lucia Formation in northern KwaZulu-Natal. A further Yezoites sp. may also be from this level. Argentoscaphites corrugatus sp. nov. occurs in the Santonian to Lower Campanian Mzamba Formation on the northernmost coast of Eastern Cape Province. Yezoites australis sp. nov. occurs in the Upper Santonian part of the St Lucia and Mzamba formations of these areas, and Scaphites reesidei Collignon, 1969, is recorded from the Lower Campanian part of the Mzamba Formation. The scaphitid assemblage includes species previously described from Western Europe and Madagascar, together with Argentoscaphites, previously known only from Patagonia (and possibly South India). Dimorphism is recognised in Scaphites reesidei, Yezoites concinna sp. nov. and Y. australis sp. nov. Argentoscaphites corrugatus sp. nov. and Yezoites sp. are represented by microconchs only. Dimorphism has not been recognised in Scaphites kieslingswaldensis.

South Africa is reputed to host the world's largest remaining population of white sharks, yet no studies have accurately determined a population estimate based on mark-recapture of live individuals. We used dorsal fin photographs (fin IDs) to identify white sharks in Gansbaai, South Africa, from January 2007-December 2011. We used the computer programme DARWIN to catalogue and match fin IDs of individuals; this is the first study to successfully use the software for white shark identification. The programme performed well despite a number of individual fins showing drastic changes in dorsal fin shape over time. Of 1682 fin IDs used, 532 unique individuals were identified. We estimated population size using the open-population POPAN parameterisation in Program MARK, which estimated the superpopulation size at 908 (95% confidence interval 808-1008). This estimated population size is considerably larger than those described at other aggregation areas of the species and is comparable to a previous South African population estimate conducted 16 years prior. Our assessment suggests the species has not made a marked recovery since being nationally protected in 1991. As such, additional international protection may prove vital for the long-term conservation of this threatened species.

St. Helena Bay, forming part of the southern Benguela ecosystem, is the largest bay on the west coast of South Africa and is a biologically important region for pelagic fish, hake, and rock lobster. To date, only a few infrequent studies have focussed on variations in the bay scale circulation. A monthly ship-based monitoring line, the St. Helena Bay Monitoring Line (SHBML), was initiated in 2000 to determine the seasonal changes in cross-shelf hydrography and biology. Even though there has been an increase in ocean modelling in and around South Africa in recent years, coastal modelling is still in its infancy. The 12-year observational data set in the St. Helena Bay region, the only long-term, cross-shelf, full water column data-set for South Africa, makes this area the perfect natural laboratory for the development of a coastal modelling system. In this study, the climatological mean temperature and salinity from three different ROMS simulations and a HYCOM simulation are evaluated against the in situ observations from the SHBML with the aim of determining the influence of different forcing products, horizontal and vertical resolution as well as vertical coordinate schemes on the vertical structure of the ocean. The model simulations tend to overestimate the temperature and salinity across the shelf, and particularly within St. Helena Bay. Furthermore, the models misrepresent the vertical salinity and temperature structures. Interestingly, below 800m, there is a better agreement between temperature in the models and the in-situ observations. This is the first detailed comparison of modelled and in-situ data for the greater St. Helena Bay area at this scale and the next phase will examine whether the model that is most congruent with the observations resolves the same interannual signals as observed in the in-situ data.

Deposition of acidifying species in the Waterberg region of South Africa and the potential for stream chemistry impacts

South Africa is rich in natural resources that include large deposits of coal. As a result more than 90% of the energy in the country is generated by 13 coal fired power stations located on the Highveld region. Over the past 7 years South Africa has experienced severe power shortages which has resulted in the approval of two new mega coal fired power stations each with a 4800 Mw generating capacity. One of these power stations is at Lephalale in the Waterberg. This region is largely dominated by a natural to semi-natural landscape, but some areas have acid sensitive sub-soils (pH < 5.5) rendering their headwater streams vulnerable to acidification. There are only three other important sources of emissions close to Lephalale, a second coal fired power station, a char plant and domestic coal combustion. In an attempt to determine baseline conditions of air pollution, deposition and stream chemistry impacts prior to the commissioning of the new PS the following measurements have been undertaken, ambient concentrations of SO2, NOx, NH3 and O3 (at seven sites since 2010), rain water chemistry ( at one site for 2015 and 2016) and headwater stream vulnerability (2015 and 2016). Concentrations of sodium (Na+), ammonium (NH4+), potassium (K+), calcium (Ca2+), magnesium (Mg2+), nitrate 21 (NO3-), chloride (Cl-), sulphate (SO42-) in the rain water will be presented and compared to other long term sites around South Africa. Total deposition of S and N will in the Lephalale region will be presented. At least 30 acid-sensitive headwater streams, many with low pH <6 and low acid neutralizing capacity that are extremely sensitive to acid deposition inputs have been identified. Future deposition in the area of acidifying species will be modelled by including emissions from the new Power station and estimates of the potential impact will be assessed.

Forest Carbon Monitoring and Reporting for REDD+: What Future for Africa?

PubMed

Gizachew, Belachew; Duguma, Lalisa A

2016-11-01

A climate change mitigation mechanism for emissions reduction from reduced deforestation and forest degradation, plus forest conservation, sustainable management of forest, and enhancement of carbon stocks (REDD+), has received an international political support in the climate change negotiations. The mechanism will require, among others, an unprecedented technical capacity for monitoring, reporting and verification of carbon emissions from the forest sector. A functional monitoring, reporting and verification requires inventories of forest area, carbon stock and changes, both for the construction of forest reference emissions level and compiling the report on the actual emissions, which are essentially lacking in developing countries, particularly in Africa. The purpose of this essay is to contribute to a better understanding of the state and prospects of forest monitoring and reporting in the context of REDD+ in Africa. We argue that monitoring and reporting capacities in Africa fall short of the stringent requirements of the methodological guidance for monitoring, reporting and verification for REDD+, and this may weaken the prospects for successfully implementing REDD+ in the continent. We presented the challenges and prospects in the national forest inventory, remote sensing and reporting infrastructures. A North-South, South-South collaboration as well as governments own investments in monitoring, reporting and verification system could help Africa leapfrog in monitoring and reporting. These could be delivered through negotiations for the transfer of technology, technical capacities, and experiences that exist among developed countries that traditionally compile forest carbon reports in the context of the Kyoto protocol.

The future of community pharmacy practice in South Africa in the light of the proposed new qualification for pharmacists: implications and challenges.

PubMed

Malangu, Ntambwe

2014-08-15

Community or retail pharmacies are regarded as one of the most common sources of health services throughout the world. In South Africa, community pharmacies have been providing some primary health care services to clients who could afford to pay. These services included screening, family planning, and emergency care for minor ailments. With the introduction of the new qualification, community pharmacies are poised to become providers of expanded services.  This paper describes the contents, the implications and challenges of the new qualification in light with future directions for community pharmacy practice in South Africa. Its purpose is to inform relevant stakeholders in South Africa and those outside South Africa that may pursue similar offerings. Published papers were identified through searches in MEDLINE and Google Scholar using a combination of search terms, namely: 'community, retail pharmacy, pharmacist/non-medical prescribing, South Africa'. Only articles published in English were considered. In addition, documents from the Ministry of Health of South Africa, the South African Pharmacy Council and curricula materials from schools of pharmacy were also reviewed. Laureates of the new qualification will essentially have the right to examine, diagnose, prescribe and monitor the treatment of their clients or patients. In doing so, this expanded function of prescribing for primary healthcare will imply several practice and infrastructural adjustments; and with many challenges laying ahead in need to be addressed. In conclusion, the authorized pharmacist prescriber qualification augurs a new era for community pharmacy practice in South Africa. This has many implications and some challenges that need to be managed. The pharmacy profession, academia, legislators and political decision-makers need to work together to resolve outstanding issues in a constructive manner.

A roaring trade? The legal trade in Panthera leo bones from Africa to East-Southeast Asia.

PubMed

Williams, Vivienne L; Loveridge, Andrew J; Newton, David J; Macdonald, David W

2017-01-01

The African lion is the only big cat listed on CITES Appendix II, and the only one for which international commercial trade is legal under CITES. The trade in lion body parts, and especially the contentious trade in bones from South Africa to Asia, has raised concerns spanning continents and cultures. Debates were amplified at the 2016 CITES Conference of the Parties (CoP17) when a proposal to up-list lions to Appendix I was not supported and a compromise to keep them on Appendix II, with a bone trade quota for South Africa, was reached instead. CoP17 underscored a need for further information on the lion bone trade and the consequences for lions across the continent. Legal international trade in bones to Asia, allegedly to supply the substitute 'tiger bone' market, began in South Africa in February 2008 when the first CITES permits were issued. It was initially unclear the degree to which bones were sourced from captive-origin lions, and whether trade was a threat to wild lion populations. Our original assessment of the legal CITES-permitted lion bone trade from South Africa to East-Southeast Asia was for the period 2008-2011 (published 2015). In this paper, we consolidate new information that has become available for 2012-2016, including CITES reports from other African countries, and data on actual exports for three years to 2016 supplied by a freight forwarding company. Thus, we update the figures on the legal trade in lion bones from Africa to East-Southeast Asia in the period 2008-2016. We also contextualise the basis for global concerns by reviewing the history of the trade and its relation to tigers, poaching and wildlife trafficking. CITES permits issued to export bones escalated from ±314y-1 skeletons from 2008-2011, to ±1312y-1 skeletons from 2013-2015. South Africa was the only legal exporter of bones to Asia until 2013 when Namibia issued permits to export skeletons to Vietnam. While CITES permits to export ±5363 skeletons from Africa to Asia from 2008-2015 were issued (99.1% from South Africa; 0.7% from Namibia) (51% for Laos), actual exports were less than stated on the permits. However, information on actual exports from 2014-2016 indicated that >3400 skeletons were exported in that period. In total, >6000 skeletons weighing no less than 70 tonnes have been shipped to East-Southeast Asia since 2008. Since few wild lions are hunted and poached within South African protected areas, skeletons for the legal trade appear to be derived from captive bred lions. However, confirmation of a 116kg shipment from Uganda to Laos, and reports of lion poaching in neighbouring countries, indicate that urgent proactive monitoring and evaluation of the legal and illegal trade is necessary in African lion range states where vulnerable wild lion populations are likely to be adversely affected.

Barriers to the Implementation of the Health and Rehabilitation Articles of the United Nations Convention on the Rights of Persons with Disabilities in South Africa

PubMed Central

Hussey, Meghan; MacLachlan, Malcolm; Mji, Gubela

2017-01-01

Background: The United Nations (UN) Convention on the Rights of Persons with Disabilities (CRPD) is a milestone in the recognition of the human rights of persons with disabilities, including the right to health and rehabilitation. South Africa has signed and ratified the CRPD but still has a long way to go in reforming policies and systems in order to be in compliance with the convention. This paper seeks to fill a gap in the literature by exploring what the barriers to the implementation of the health and rehabilitation articles of the CRPD are, as identified by representatives of the disability community. Methods: This investigation used a qualitative, exploratory methodology. 10 semi-structured interviews of a purposive sample of representatives of disabled persons organizations (DPOs), non-governmental organizations (NGOs), and service providers in South Africa were conducted. Participants were drawn from urban, peri-urban, and rural settings in order to reflect diverse perspectives within South Africa. Data was analysed using a multi-stage coding process to establish the main categories and relationships between them. Results: Six main categories of barriers to the implementation of the health and rehabilitation articles of the CRPD were identified. Attitude barriers including stigma and negative assumptions about persons with disabilities were seen as an underlying cause and influence on all of the other categories; which included political, financial, health systems, physical, and communication barriers. Conclusion: The findings of this study have important implications for strategies and actions to implement the CRPD. Given the centrality of attitudinal barriers, greater sensitization around the area of disability is needed. Furthermore, disability should be better integrated and mainstreamed into more general initiatives to develop the health system and improve the lives of persons living in poverty in South Africa.

Surveillance using admissions to hospital, while being useful, is a poor indicator of the real incidence of disease encountered by travelers. An alternative is self-reported illness among those who attended at a pretravel clinic prior to their travels. Estimates of incidence and risk factors were determined for attendees at a travel clinic in Scotland using a questionnaire. Analysis for risk factors was carried out for those travelers visiting countries in Africa, Asia, or South and Central America, who had traveled for 1 week or more and had returned between 1997 and 2001 (N= 4,856). Multivariate logistic regression was used to test the hypotheses that time abroad and age-group would be significant for both respiratory and diarrheal symptoms regardless of which of the three geographical areas are visited. From 2006 returned questionnaires (response rate = 41.3%), diarrhea and respiratory symptoms were reported by 44.2 and 16.8% of respondents, respectively; the incidence was significantly greater among travelers to Asia for both diarrheal (55.5%) and respiratory (23.7%) symptoms than among travelers to Africa (36.6 and 12.2%, respectively) or South and Central America (39.5 and 16.2%, respectively). For diarrhea, age was a highly significant risk factor for travelers to Asia, South and Central America, and Africa. Being a self-organized tourist/backpacker, traveling to Asia was associated with increased risk, while for Africa and South and Central America visiting family or friends was associated with a lower risk. For travelers to Asia, traveling to the Indian subcontinent was significantly associated with increased risk. The majority of travelers had an adverse event while traveling abroad, with diarrhea and respiratory conditions being especially common despite attending a travel clinic for advice prior to departure. However, the limitations of this surveillance-based strategy have highlighted the requirement for more research to understand more fully the issues of risk and incidence among travelers to high-risk destinations from Scotland.

Maternal collapse: Training in resuscitation.

2015-11-01

The National Committee for the Confidential Enquiries into Maternal Deaths (NCCEMD) of South Africa has recommended in the Sixth Saving Mothers Report that health-care professionals (HCPs) training in managing obstetric emergencies be improved. One such measure is to ensure that the Essential Steps in Managing Obstetric Emergencies (ESMOE) with its Emergency Obstetric Simulation Training (EOST) be rolled out to every HCP working in the obstetric environment. The programme has been strengthened and rolled out in the province of KwaZulu-Natal, South Africa. This review focuses on the various teaching methods used to improve maternal resuscitation training in a South African context. Evidence-based interventions in maternal resuscitation will be highlighted, and recommendations for clinical practice will be suggested. Common causes of maternal collapse will be explored, and measures to improve training in these areas will be outlined. In order to ensure sustainability, quality improvement measures need to be introduced and evaluated. Copyright © 2015 Elsevier Ltd. All rights reserved.

Lead reduction of petrol and blood lead concentrations of athletes

Maresky, L.S.; Kotze, T.J.V.W.; Grobler, S.R.

In 1984, it was determined that the blood of long-distance runners in South Africa contained unacceptably high concentrations of lead. Subsequently, the petrol lead level in South Africa was reduced from 0.8 g/l to 0.4 g/l. In view of this reduction, a follow-up investigation of its effect on the blood lead concentration of South African runners was undertaken. Blood lead samples were analyzed by graphite furnace atomic absorption spectrophotometry. The mean values of blood lead concentrations dropped from 52 to 13 {mu}g/dl and from 20 to 8.5 {mu}g/dl for the urban and rural trainers, respectively. A highly significant decrease inmore » blood lead levels was found and was mainly attributable to the reduction in the petrol lead levels. The blood lead results for rural trainers indicated that there still exists a certain degree of lead pollution in athletes from nonremote areas.« less

The diagnosis of AIDS in 1982 in South Africa was followed by a rapid rise in the number of people living with the virus and dying from AIDS-related illnesses. The 2016 report by the Statistics South Africa indicated that about 7.03 million South Africans were infected with HIV/AIDS - the highest rate in the world. Despite the emergence of effective drugs in the mid-1990s, medical treatment remained unavailable in South Africa, particularly in public hospitals. This prompted civil society groups to establish platforms to discuss health policy change in South Africa. Prominent among these was the Treatment Action Campaign (TAC), formed in 1998, which aimed to advocate for improved HIV/AIDS health service delivery. The efforts succeeded in shaping the current HIV/AIDS policy through various initiatives such as the use of constitutional law in legal action against profiteering drug companies. This paper examines the role of civil society, and particularly the TAC engagement with the state in health policy making, and the subsequent implementation of health policy on HIV/AIDS in post-apartheid South Africa.

The purpose of this study was to estimate the economic burden of violence against children in South Africa. We assembled summative estimates of lifetime prevalence, calculated the magnitude of associations with negative outcomes, and thereby estimated the economic burden of violence against children. According to our calculations, 2.3 million and 84,287 disability-adjusted life-years (DALYs) lost in South Africa in 2015 were attributable to nonfatal and fatal violence against children, respectively. The estimated economic value of DALYs lost to violence against children (including both fatal and nonfatal) in South Africa in 2015 totalled ZAR173 billion (US $13.5 billion)—or 4.3% of South Africa’s gross domestic product (GDP) in 2015. In addition, the reduced earnings attributable to childhood physical violence and emotional violence in South Africa in 2015 were ZAR25.2 billion (US $2.0 billion) and ZAR9.6 billion (US $750 million), respectively. In addition, South Africa spent ZAR1.6 billion (US $124 million) on child care and protection in fiscal year 2015/2016, many of which costs are directly related to violence against children. This study confirms the importance of prioritising violence against children as a key social and economic concern for South Africa’s future. PMID:29165332

Producing alcohol and other drugs as a policy 'problem': A critical analysis of South Africa's 'National Drug Master Plan' (2013-2017).

PubMed

Pienaar, Kiran; Savic, Michael

2016-04-01

The strong symbolic value of illicit drug use makes it a contested issue, which attracts mixed public opinion, intense media attention and close political scrutiny. This means that the formulation of plausible, authoritative policies governing illicit drugs must navigate fraught political terrain. In a country like South Africa with its long unique history of institutionalised oppression of the black majority, the issues confronting drug policy are particularly complex and the need for carefully formulated policy responses especially urgent. Yet despite this, the area of drug policy development in South Africa has received little scholarly attention to date. This paper explores the complexities of policymaking in the South African context by drawing on feminist scholar Carol Bacchi's poststructuralist approach to policy analysis, which focuses on how policy helps to produce the problems it purports to solve. Taking as its empirical focus, South Africa's current drug policy, the third National Drug Master Plan (NDMP), 2013-2017, the paper analyses how the policy constitutes the 'problem of alcohol and other drugs' (AODs). We identify three central policy proposals through which specific problematisations emerge: (1) the proposal that drug use is a global issue requiring a coordinated policy response, (2) appeals to evidence-based policy proposals and (3) the proposal that AOD 'use' and 'abuse' be treated interchangeably. We suggest that these proposals reveal a tendency towards inflating the 'problem of AODs' and thus work to justify punitive policy measures. In an effort to explore the implications of particular problematisations for effecting social change, we clarify the ways in which the policy may work to undermine the interests of those it seeks to aid by reinforcing stigma and marginalisation.

GHG emission factors developed for the recycling and composting of municipal waste in South African municipalities

DOE Office of Scientific and Technical Information (OSTI.GOV)

Friedrich, Elena, E-mail: Friedriche@ukzn.ac.za; Trois, Cristina

2013-11-15

Highlights: • GHG emission factors for local recycling of municipal waste are presented. • GHG emission factors for two composting technologies for garden waste are included. • Local GHG emission factors were compared to international ones and discussed. • Uncertainties and limitations are presented and areas for new research highlighted. - Abstract: GHG (greenhouse gas) emission factors for waste management are increasingly used, but such factors are very scarce for developing countries. This paper shows how such factors have been developed for the recycling of glass, metals (Al and Fe), plastics and paper from municipal solid waste, as well asmore » for the composting of garden refuse in South Africa. The emission factors developed for the different recyclables in the country show savings varying from −290 kg CO{sub 2} e (glass) to −19 111 kg CO{sub 2} e (metals – Al) per tonne of recyclable. They also show that there is variability, with energy intensive materials like metals having higher GHG savings in South Africa as compared to other countries. This underlines the interrelation of the waste management system of a country/region with other systems, in particular with energy generation, which in South Africa, is heavily reliant on coal. This study also shows that composting of garden waste is a net GHG emitter, releasing 172 and 186 kg CO{sub 2} e per tonne of wet garden waste for aerated dome composting and turned windrow composting, respectively. The paper concludes that these emission factors are facilitating GHG emissions modelling for waste management in South Africa and enabling local municipalities to identify best practice in this regard.« less

Challenging urban health: towards an improved local government response to migration, informal settlements, and HIV in Johannesburg, South Africa

PubMed Central

Vearey, Joanna

2011-01-01

This article is a review of the PhD thesis undertaken by Joanna Vearey that explores local government responses to the urban health challenges of migration, informal settlements, and HIV in Johannesburg, South Africa. Urbanisation in South Africa is a result of natural urban growth and (to a lesser extent) in-migration from within the country and across borders. This has led to the development of informal settlements within and on the periphery of urban areas. The highest HIV prevalence nationally is found within urban informal settlements. South African local government has a ‘developmental mandate’ that calls for government to work with citizens to develop sustainable interventions to address their social, economic, and material needs. Through a mixed-methods approach, four studies were undertaken within inner-city Johannesburg and a peripheral urban informal settlement. Two cross-sectional surveys – one at a household level and one with migrant antiretroviral clients – were supplemented with semi-structured interviews with multiple stakeholders involved with urban health and HIV in Johannesburg, and participatory photography and film projects undertaken with urban migrant communities. The findings show that local government requires support in developing and implementing appropriate intersectoral responses to address urban health. Existing urban health frameworks do not deal adequately with the complex health and development challenges identified; it is essential that urban public health practitioners and other development professionals in South Africa engage with the complexities of the urban environment. A revised, participatory approach to urban health – ‘concept mapping’ – is suggested which requires a recommitment to intersectoral action, ‘healthy urban governance’ and public health advocacy.

Factors influencing the increasing prevalence of overweight/obesity among children and adolescents in sub-Saharan Africa remain unclear. We assessed the prevalence and determinants of overweight and obesity and effects on cardio-metabolic profile in school learners in the Western Cape, South Africa. Cross-sectional data were collected from 7 to 18-year-old South African school learners attending 14 schools, randomly selected from 107 government schools in the areas. The learners were selected through stratified random sampling techniques. Logistic regressions were used to assess the determinants of overweight/obesity and its association with cardio-metabolic profile. Among the 1559 participants, the overall prevalence of overweight/obesity was 22.9%. Being a girl (Odds ratio 2.51, 95% CI: 1.92-3.29), or Black African (1.35, 1.04-.75) was associated with increased odds of being overweight/obese. The identified health consequences among the overweight/obese learners differed between the ethnic groups. Overweight/obese coloured (mixed ancestry) learners were more likely to have hypertension (3.27, 1.18-9.08), hypertriglyceridemia (1.94, 0.99-3.78) and low high-density lipoprotein cholesterol (HDL-C) (3.65, 2.33-5.72), overweight/obese Black African learners had higher odds for hypertension (3.62, 1.31-10.04) and low HDL-C (1.56, 1.01-2.40) and overweight/obese White learners were prone to low HDL-C (5.04, 1.35-18.80). Overweight/obesity is highly prevalent among school learners in Western Cape (South Africa), with being female or Black African increasing the odds. That overweight/obesity is also associated with adverse cardio-metabolic risk profile aggravates the problem and suggests worse cardiovascular outcomes in South African young adults in the future.

Discrimination against breastfeeding: a racial/economic issue?

PubMed

Auerbach, K G

1989-03-01

Black mothers in South Africa are more likely to breast feed than white mothers, and for a longer period of time. During hospital visits the author observed nurseries in which black mothers fed their children while white mothers did not. In the nurseries for white mothers there were many advertisements from formula companies promoting their products. Because of overcrowding black mothers are usually released 24 hours after birth. There are billboards advertising baby foods in the black areas also, and the cost of these foods is more than most can afford. Using these foods often leads to dehydration, and if the child is not treated in a rehydration center, it dies. Also, the family may suffer when money is used for the more costly formula when less expensive foods could feed the whole family. In the US many black women on welfare are given formula for their children, since many health workers and others are not interested in or ignorant of breastfeeding benefits. Compared to white South African women, fewer white women breastfeed, but they do it longer. There is also extensive promotion of gadgets to assist breast feeding mothers in the US including breast pumps, breast pads, and nipple shields. Some of these are in use in South Africa are just as useless there. In South Africa affluent white women do not breastfeed while in the US more do. In the US poor black women do not breastfeed while in South Africa they do. From these observations it appears that non-western health care systems are more supportive of breastfeeding than the western systems. One might examine the question of social class and racial issues involved, also.

Domestic rainwater harvesting to improve water supply in rural South Africa

NASA Astrophysics Data System (ADS)

Mwenge Kahinda, Jean-marc; Taigbenu, Akpofure E.; Boroto, Jean R.

Halving the proportion of people without sustainable access to safe drinking water and basic sanitation, is one of the targets of the 7th Millennium Development Goals (MDGs). In South Africa, with its mix of developed and developing regions, 9.7 million (20%) of the people do not have access to adequate water supply and 16 million (33%) lack proper sanitation services. Domestic Rainwater Harvesting (DRWH), which provides water directly to households enables a number of small-scale productive activities, has the potential to supply water even in rural and peri-urban areas that conventional technologies cannot supply. As part of the effort to achieve the MDGs, the South African government has committed itself to provide financial assistance to poor households for the capital cost of rainwater storage tanks and related works in the rural areas. Despite this financial assistance, the legal status of DRWH remains unclear and DRWH is in fact illegal by strict application of the water legislations. Beyond the cost of installation, maintenance and proper use of the DRWH system to ensure its sustainability, there is risk of waterborne diseases. This paper explores challenges to sustainable implementation of DRWH and proposes some interventions which the South African government could implement to overcome them.

The current rate of deforestation in Africa constitutes a serious danger to the future of medicinal plants on this continent. Conservation of these medicinal plants in the field and the scientific documentation of our knowledge about them are therefore crucial. An ethnobotanical survey of plants used for the treatment of tuberculosis (TB) was carried out in selected areas of the Eastern Cape, South Africa. These areas were Hala, Ncera, Sheshegu, and Gquamashe, all within the Nkonkobe Municipality. One hundred informants were interviewed. The survey included the identification of scientific and vernacular names of the plants used for treatment of TB as well as the methods of preparation and administration, the part used, dosage, and duration of treatment. The survey revealed 30 plants belonging to 21 families which are commonly used by traditional healers for the treatment of TB and associated diseases. Of these plants Clausena anisata, Haemanthus albiflos, and Artemisia afra were the most cited. The leaves were the most common part used in the medicinal preparations. Our findings are discussed in relation to the importance of the documentation of medicinal plants. PMID:24864158

A strategy to implement and support pre-hospital emergency medical systems in developing, resource-constrained areas of South Africa.

2014-01-01

Resource-constrained countries are in extreme need of pre-hospital emergency care systems. However, current popular strategies to provide pre-hospital emergency care are inappropriate for and beyond the means of a resource-constrained country, and so new ones are needed-ones that can both function in an under-developed area's particular context and be done with the area's limited resources. In this study, we used a two-location pilot and consensus approach to develop a strategy to implement and support pre-hospital emergency care in one such developing, resource-constrained area: the Western Cape province of South Africa. Local community members are trained to be emergency first aid responders who can provide immediate, on-scene care until a Transporter can take the patient to the hospital. Management of the system is done through local Community Based Organizations, which can adapt the model to their communities as needed to ensure local appropriateness and feasibility. Within a community, the system is implemented in a graduated manner based on available resources, and is designed to not rely on the whole system being implemented first to provide partial function. The University of Cape Town's Division of Emergency Medicine and the Western Cape's provincial METRO EMS intend to follow this model, along with sharing it with other South African provinces.

Including irrigation in niche modelling of the invasive wasp Vespula germanica (Fabricius) improves model fit to predict potential for further spread

PubMed Central

Kriticos, Darren J.; Veldtman, Ruan

2017-01-01

The European wasp, Vespula germanica (Fabricius) (Hymenoptera: Vespidae), is of Palaearctic origin, being native to Europe, northern Africa and Asia, and introduced into North America, Chile, Argentina, Iceland, Ascension Island, South Africa, Australia and New Zealand. Due to its polyphagous nature and scavenging behaviour, V. germanica threatens agriculture and silviculture, and negatively affects biodiversity, while its aggressive nature and venomous sting pose a health risk to humans. In areas with warmer winters and longer summers, queens and workers can survive the winter months, leading to the build-up of large nests during the following season; thereby increasing the risk posed by this species. To prevent or prepare for such unwanted impacts it is important to know where the wasp may be able to establish, either through natural spread or through introduction as a result of human transport. Distribution data from Argentina and Australia, and seasonal phenology data from Argentina were used to determine the potential distribution of V. germanica using CLIMEX modelling. In contrast to previous models, the influence of irrigation on its distribution was also investigated. Under a natural rainfall scenario, the model showed similarities to previous models. When irrigation is applied, dry stress is alleviated, leading to larger areas modelled climatically suitable compared with previous models, which provided a better fit with the actual distribution of the species. The main areas at risk of invasion by V. germanica include western USA, Mexico, small areas in Central America and in the north-western region of South America, eastern Brazil, western Russia, north-western China, Japan, the Mediterranean coastal regions of North Africa, and parts of southern and eastern Africa.

Khan, Muhammad Tariq Iqbal; Yaseen, Muhammad Rizwan; Ali, Qamar

2018-06-08

This study explored the long-run association among greenhouse gases (GHGs), financial development, forest area, improved sanitation, renewable energy, urbanization, and trade in 24 lower middle-income countries from Asia, Europe, Africa, and America (South and North) by using panel data from 1990 to 2015. Granger causality was tested by Toda and Yamamoto approach. The bi-directional causality was established among urbanization and GHGs (Asia), financial development and forest (Asia), energy use and renewable energy (Asia), renewable energy and forest (Asia), improved sanitation and forest (Asia, Africa, America), urbanization and forest (Asia), and improved sanitation and financial development (Europe). The GHG emission also shows one-way causality is running from financial development to GHG (America), energy to GHG (Asia), renewable energy to GHG (America), forest area to GHG (America), trade openness to GHG (Africa), urbanization to GHG (Europe), GHG to financial development (Europe), GHG to energy use (Europe, Africa, and America), and GHG to trade openness (Asia). On the basis of fully modified ordinary least square and generalized method of moment, the reciprocal relationship of GHGs was observed due to financial development in Asia and Africa; renewable energy in all panels; forest area in Asia, Europe, and America; improved sanitation in Asia, Africa, and America; trade openness in Africa; and urbanization in Europe and America. Policymakers should concentrate on these variables for the reduction in GHGs. The annual convergence towards long-run equilibrium was 50.5, 31.9, and 20.9% for America, Asia, and Africa, respectively.

2016-01-01

Due to both deliberate and accidental introductions, invasive African Clawed Frog (Xenopus laevis) populations have become established worldwide. In this study, we investigate the geographic origins of invasive X. laevis populations in France and Portugal using the phylogeographic structure of X. laevis in its native South African range. In total, 80 individuals from the whole area known to be invaded in France and Portugal were analysed for two mitochondrial and three nuclear genes, allowing a comparison with 185 specimens from the native range. Our results show that native phylogeographic lineages have contributed differently to invasive European X. laevis populations. In Portugal, genetic and historical data suggest a single colonization event involving a small number of individuals from the south-western Cape region in South Africa. In contrast, French invasive X. laevis encompass two distinct native phylogeographic lineages, i.e., one from the south-western Cape region and one from the northern regions of South Africa. The French X. laevis population is the first example of a X. laevis invasion involving multiple lineages. Moreover, the lack of population structure based on nuclear DNA suggests a potential role for admixture within the invasive French population. PMID:26855879

When, and how, should we introduce a combination measles-mumps-rubella (MMR) vaccine into the national childhood expanded immunization programme in South Africa?

PubMed

Cameron, Neil A

2012-09-07

This article briefly reviews the history and epidemiology of measles, mumps and rubella disease and the case for introducing combination measles-mumps-rubella (MMR) vaccine into the national childhood immunization schedule in South Africa. Despite adopting the World Health Organization's Measles Elimination strategy in 1996 and achieving a significant decrease the incidence of measles, added effort is needed in South and southern Africa to reach the goal to eliminate endogenous spread measles. Mumps is still common disease of childhood and while there are few sequelae, even the rare complications are important in large populations. Congenital rubella syndrome is seldom reported, but it is estimated that of the million or so children born every year in South Africa over 600 infants are affected to some degree by rubella infection. The naturally acquired immunity to rubella in women of childbearing age in South Africa has been estimated at over 90%, so that introducing a rubella containing vaccine in childhood may paradoxically increase the proportion of girls reaching puberty still susceptible to rubella. The elimination of endogenous measles and rubella is being achieved in many countries in South America, and despite the recent measles epidemic, must still be seriously considered for South and southern Africa. Current constraints and potential steps needed to reach the goal in South Africa are discussed. Copyright © 2012 Elsevier Ltd. All rights reserved.

Estimating agricultural yield gap in Africa using MODIS NDVI dataset

Luan, Y.; Zhu, W.; Luo, X.; Liu, J.; Cui, X.

2013-12-01

Global agriculture has undergone a period of rapid intensification characterized as 'Green Revolution', except for Africa, which is the region most affected by unreliable food access and undernourishment. Increasing crop production will be one of the most challenges and most effectual way to mitigate food insecurity there, as Africa's agricultural yield is on a much lower level comparing to global average. In this study we characterize cropland vegetation phenology in Africa based on MODIS NDVI time series between 2000 and 2012. Cumulated NDVI is a proxy for net primary productivity and used as an indicator for evaluating the potential yield gap in Africa. It is achieved via translating the gap between optimum attainable productivity level in each classification of cropping systems and actual productivity level by the relationship of cumulated NDVI and cereal-equivalent production. The results show most of cropland area in Africa have decreasing trend in cumulated NDVI, distributing in the Nile Delta, Eastern Africa and central of semi-arid to arid savanna area, except significant positive cumulated NDVI trends are mainly found between Senegal and Benin. Using cumulated NDVI and statistics of cereal equivalent production, we find remarkable potential yield gap at the Horn of East Africa (especially in Somalia), Northern Africa (Morocco, Algeria and Tunisia). Meanwhile, countries locating at the savanna area near Sahel desert and South Africa also show significant potential, though they already have a relatively high level of productivity. Our results can help provide policy recommendation for local government or NGO to tackle food security problems by identifying zones with high potential of yield improvement.

For each of these species, illustrations are provided of adult beetles of both sexes as well as illustrations of male reproductive structures, morphological redescriptions, discussions of morphological variation, annual activity histograms, and maps of occurrence localities in the Republic of South Africa. Maps of occurrence localities for these species are compared against ecoregional and vegetation maps of southern Africa; each species of Anthia shows a different pattern of occupancy across the suite of ecoregions and vegetation types in the Republic of South Africa. Information about predatory and foraging behaviors, Müllerian mimicry, and small-scale vegetation community associations is presented for Anthia thoracica based on field and laboratory studies in Kruger National Park, South Africa.

Use of forensic analysis to better understand shark attack behaviour.

PubMed

Ritter, E; Levine, M

2004-12-01

Shark attacks have primarily been analyzed from wound patterns, with little knowledge of a shark's approach, behaviour and intention leading to such wounds. For the first time, during a shark-human interaction project in South Africa, a white shark, Carcharodon carcharias, was filmed biting a vertically positioned person at the water surface, and exhibiting distinct approach patterns leading to the bite. This bite was compared to ten white shark attacks that occurred (i) in the same geographical area of South Africa, and (ii) where the same body parts were bitten. Close similarity of some of these wound patterns to the bite imprint of the videotaped case indicate that the observed behaviour of the white shark may represent a common pattern of approaching and biting humans.

2006-12-01

A genotype 2 lyssavirus, Lagos bat virus (LBV), was isolated from a terrestrial wildlife species (water mongoose) in August 2004 in the Durban area of the KwaZulu-Natal Province of South Africa. The virus isolate was confirmed as LBV by antigenic and genetic characterization, and the mongoose was identified as Atilax paludinosus by mitochondrial cytochrome b sequence analysis. Phylogenetic analysis demonstrated sequence homology with previous LBV isolates from South African bats. Studies performed in mice indicated that the peripheral pathogenicity of LBV had been underestimated in previous studies. Surveillance strategies for LBV in Africa must be improved to better understand the epidemiology of this virus and to make informed decisions on future vaccine strategies because evidence is insufficent that current rabies vaccines provide protection against LBV.

Setting priorities in health research using the model proposed by the World Health Organization: development of a quantitative methodology using tuberculosis in South Africa as a worked example.

PubMed

Hacking, Damian; Cleary, Susan

2016-02-09

Setting priorities is important in health research given the limited resources available for research. Various guidelines exist to assist in the priority setting process; however, priority setting still faces significant challenges such as the clear ranking of identified priorities. The World Health Organization (WHO) proposed a Disability Adjusted Life Year (DALY)-based model to rank priorities by research area (basic, health systems and biomedical) by dividing the DALYs into 'unavertable with existing interventions', 'avertable with improved efficiency' and 'avertable with existing but non-cost-effective interventions', respectively. However, the model has conceptual flaws and no clear methodology for its construction. Therefore, the aim of this paper was to amend the model to address these flaws, and develop a clear methodology by using tuberculosis in South Africa as a worked example. An amended model was constructed to represent total DALYs as the product of DALYs per person and absolute burden of disease. These figures were calculated for all countries from WHO datasets. The lowest figures achieved by any country were assumed to represent 'unavertable with existing interventions' if extrapolated to South Africa. The ratio of 'cost per patient treated' (adjusted for purchasing power and outcome weighted) between South Africa and the best country was used to calculate the 'avertable with improved efficiency section'. Finally, 'avertable with existing but non-cost-effective interventions' was calculated using Disease Control Priorities Project efficacy data, and the ratio between the best intervention and South Africa's current intervention, irrespective of cost. The amended model shows that South Africa has a tuberculosis burden of 1,009,837.3 DALYs; 0.009% of DALYs are unavertable with existing interventions and 96.3% of DALYs could be averted with improvements in efficiency. Of the remaining DALYs, a further 56.9% could be averted with existing but non-cost-effective interventions. The amended model was successfully constructed using limited data sources. The generalizability of the data used is the main limitation of the model. More complex formulas are required to deal with such potential confounding variables; however, the results act as starting point for development of a more robust model.

Determining the efficacy of national strategies aimed at addressing the challenges facing health personnel working in rural areas in KwaZulu-Natal, South Africa

PubMed Central

2017-01-01

Background Shortages of Human Resources for Health (HRH) in rural areas are often driven by poor working and living conditions, inadequate salaries and benefits, lack of training and career development opportunities amongst others. The South African government has adopted a human resource strategy for the health sector in 2011 aimed at addressing these challenges. Aim This study reviews the challenges faced by health personnel against government strategies aimed at attracting and retaining health personnel in these underserved areas. Setting The study was conducted in six primary health care service sites in the Hlabisa sub-district of Umkhanyakude, located in northern KwaZulu-Natal, South Africa. Methods The study population comprised 25 health workers including 11 professional nurses, 4 staff nurses and 10 doctors (4 medical doctors, 3 foreign medical doctors and 3 doctors undertaking community service). Qualitative data were collected from semi-structured interviews and analysed using thematic analysis. Results Government initiatives including the rural allowance, deployment of foreign medical doctors and the presence of health personnel undertaking their community service in rural areas are positively viewed by health personnel working in rural health facilities. However, poor living and working conditions, together with inadequate personal development opportunities, remain unresolved challenges. It is these challenges that will continue to dissuade experienced health personnel from remaining in these underserved areas. Conclusion South Africa’s HRH strategy for the Health Sector 2012/13–2015/16 had highlighted the key challenges raised by respondents and identified strategies aimed at addressing these challenges. Implementation of these strategies is key to improving both living and working conditions, and providing health personnel with opportunities for further development will require inter-ministerial collaboration if the HRH 2030 objectives are to be realised.

Plant invasions are a serious threat to natural and semi-natural ecosystems worldwide. Most management-orientated research on invasions focuses on invaders that are already widespread and often have major impacts. This paper deals with "emerging" invaders-those alien species with the potential to become important problems without timely intervention. A climate matching procedure was developed to define areas of South Africa, Lesotho and Swaziland that could be invaded by 28 plant species that had previously been classified as emerging invaders. Information on the location of populations of these species in the study area was combined with information on their distributions (as native or alien) in parts of Australia and the United States of America. These two countries had the best available distribution data for this study. They also share many invasive alien plant species with South Africa. Climatic data obtained for weather stations near points of known occurrence in these countries were used to define the climatically suitable areas for each species in the study area. Almost 80% of the remaining natural environment in southern Africa was found to be vulnerable to invasion by at least one of these species, 50% by six or more and 24% by 16 or more species. The most vulnerable areas are the highveld grasslands and the eastern escarpment. The emerging invaders with the greatest potential range included Acacia podalyriifolia and Cortaderia selloana. The globally important invaders Ulex europaeus and Lythrum salicaria had a more limited invasion potential but could still become major invaders. There was no relationship between the extent of the climatically suitable areas for the different species and an expert ranking of their invasion potential, emphasising the uncertainties inherent in making expert assessments based on very little information. The methods used in this analysis establish a protocol for future modelling exercises to assess the invasion potential of other emerging invaders.

The response of South African professional psychology associations to apartheid.

Nicholas, L J

1990-01-01

Professional psychology associations in South Africa have overtly and covertly furthered the aims of apartheid. Guidance about the ethical obligations of psychologists in the South African context has been singularly lacking, and as a result blacks have not been attracted to the profession of psychology in sufficient numbers to administer to psychological needs of the client population. The political dimension of psychological practice in South Africa needs to be addressed directly so that healing strategies relevant to the burgeoning racial conflict in South Africa can be implemented.

The pollination ecology of an assemblage of grassland asclepiads in South Africa.

Ollerton, Jeff; Johnson, Steven D; Cranmer, Louise; Kellie, Sam

2003-12-01

The KwaZulu-Natal region of South Africa hosts a large diversity of asclepiads (Apocynaceae: Asclepiadoideae), many of which are endemic to the area. The asclepiads are of particular interest because of their characteristically highly evolved floral morphology. During 3 months of fieldwork (November 2000 to January 2001) the flower visitors and pollinators to an assemblage of nine asclepiads at an upland grassland site were studied. These observations were augmented by laboratory studies of flower morphology (including scanning electron microscopy) and flower colour (using a spectrometer). Two of the specialized pollination systems that were documented are new to the asclepiads: fruit chafer pollination and pompilid wasp pollination. The latter is almost unique in the angiosperms. Taxa possessing these specific pollination systems cluster together in multidimensional phenotype space, suggesting that there has been convergent evolution in response to similar selection to attract identical pollinators. Pollination niche breadth varied from the very specialized species, with only one pollinator, to the more generalized, with up to ten pollinators. Pollinator sharing by the specialized taxa does not appear to have resulted in niche differentiation in terms of the temporal or spatial dimensions, or with regards to placement of pollinaria. Nestedness analysis of the data set showed that there was predictability and structure to the pattern of plant-pollinator interactions, with generalist insects visiting specialized plants and vice versa. The research has shown that there is still much to be learned about plant-pollinator interactions in areas of high plant diversity such as South Africa.

Multidrug-resistant and extensively drug-resistant tuberculosis: implications for the HIV epidemic and antiretroviral therapy rollout in South Africa.

PubMed

Andrews, Jason R; Shah, N Sarita; Gandhi, Neel; Moll, Tony; Friedland, Gerald

2007-12-01

Drug-resistant tuberculosis (TB) is emerging as a major clinical and public health challenge in areas of sub-Saharan Africa where there is a high prevalence of human immunodeficiency virus (HIV) infection. TB drug-resistance surveillance in this region has been limited by laboratory capacity and the public health infrastructure; however, with the maturation of the HIV epidemic, the burden of drug-resistant TB is increasing rapidly. The recent discovery of large numbers of cases of multidrug-resistant (MDR) TB and extensively drug-resistant (XDR) TB in South Africa likely represents an unrecognized and evolving epidemic rather than sporadic, localized outbreaks. The combination of a large population of HIV-infected susceptible hosts with poor TB treatment success rates, a lack of airborne infection control, limited drug-resistance testing, and an overburdened MDR-TB treatment program provides ideal conditions for an MDR-TB and XDR-TB epidemic of unparalleled magnitude. In the present article, we review the history of drug-resistant TB in South Africa, describe its interaction with the HIV epidemic and the resultant consequences, and suggest measures necessary for controlling MDR-TB and XDR-TB in this context. A successful response to the emergence of MDR-TB and XDR-TB will necessitate increased resources for and collaboration between TB and HIV programs.

Michael, K

1999-01-01

This article presents the 1998 survey results conducted by the Health Economics and HIV/AIDS Research Division of the University of Natal in South Africa with the goal of documenting the best practices of managing HIV/AIDS in the workplace. The five key areas of the study are: HIV prevention; managing ill health; human resource development and industrial relations; employee benefits and survivor support; monitoring and planning for change in the workplace. The research comprised 14 companies used during the case studies. A few notable cases were observed among companies attempting to create awareness about HIV/AIDS. The Best Practice Survey highlighted issues about the private sectors in South Africa and their HIV management. First, companies conceptualize AIDS as either a health or poverty problem. Second, the environment is affected by the hazards of economic downturns, labor action, and economic inflation while the AIDS problem is neglected. Third, indirect costs were not considered and most companies feel that the conversion to a defined contribution arrangement compensates against escalating payouts for benefits. Fourth, long-term plans of the companies did not utilize the ill health statistics for the past 5 years.

Development of one-minute rain-rate and rain-attenuation contour maps for satellite propagation system planning in a subtropical country: South Africa

NASA Astrophysics Data System (ADS)

Ojo, J. S.; Owolawi, P. A.

2014-10-01

Millimeter and microwave system design at higher frequencies require as input a 1-min rain-rate cumulative distribution function for estimating the level of degradation that can be encountered at such frequency bands. Owing to the lack of 1-min rain-rate data in South Africa and the availability of 5-min and hourly rainfall data, we have used rain-rate conversion models and the refined Moupfouma model to convert the available data into 1-min rain-rate statistics. The attenuation caused by these rain rates was predicted using the International Telecommunication Union (ITU) recommendations model. The Kriging interpolation method was used to draw contour maps over different percentages of time for spatial interpolation of rain-rate values into a regular grid in order to obtain a highly consistent and predictable inter-gauge rain-rate variation over South Africa. The present results will be useful for system designers of modern broadband wireless access (BWA) and high-density cell-based Ku/Ka, Q/V band satellite systems, over the desired area of coverage in order to determine the appropriate effective isotropically radiated power (EIRP) and receiver characteristics of this region.

Cultural phylogeography of the Bantu Languages of sub-Saharan Africa.

PubMed

Currie, Thomas E; Meade, Andrew; Guillon, Myrtille; Mace, Ruth

2013-07-07

There is disagreement about the routes taken by populations speaking Bantu languages as they expanded to cover much of sub-Saharan Africa. Here, we build phylogenetic trees of Bantu languages and map them onto geographical space in order to assess the likely pathway of expansion and test between dispersal scenarios. The results clearly support a scenario in which groups first moved south through the rainforest from a homeland somewhere near the Nigeria-Cameroon border. Emerging on the south side of the rainforest, one branch moved south and west. Another branch moved towards the Great Lakes, eventually giving rise to the monophyletic clade of East Bantu languages that inhabit East and Southeastern Africa. These phylogenies also reveal information about more general processes involved in the diversification of human populations into distinct ethnolinguistic groups. Our study reveals that Bantu languages show a latitudinal gradient in covering greater areas with increasing distance from the equator. Analyses suggest that this pattern reflects a true ecological relationship rather than merely being an artefact of shared history. The study shows how a phylogeographic approach can address questions relating to the specific histories of certain groups, as well as general cultural evolutionary processes.

Earth observations Cape Town, South Africa taken during the STS-97 mission

NASA Image and Video Library

2000-12-10

STS097-711-069 (30 Nov. - 11 Dec. 2000) This view featuring Cape Town and the Western Cape Province in the Republic of South Africa was provided by one of the STS-97 astronauts using a 70mm handheld camera aboard the Earth-orbiting Space Shuttle Endeavour. The capital and largest city of Western Cape Province, Cape Town (1995 population in the urban and suburban area shows in excess of 1.9 million), is visible between False Bay (large, U-shaped bay) and a smaller bay along the Atlantic coast of the peninsula. Within the urban built-up area some of the infrastructure of Cape Town, including the city center and the harbor and waterfront facilities, can be identified near the small bay (middle left edge of the image). Table Mountain elevation of 3563 feet (1086 meters above sea level) separates the city center (north of the mountain) from the southern suburbs of Cape Town. The Cape of Good Hope, long famous as the gateway from the Atlantic Ocean to the Indian Ocean, is located at the southern tip of the claw-shaped peninsula. False Bay is a popular recreational region for the local residents of the greater Cape Town region, as well as a tourist attraction for people who live beyond the borders of South Africa. The lighter-colored terrain, mainly north of Cape Town, shows a landscape of large, cultivated field patterns. These coastal plains are separated from the interior by a chain of folded mountain ranges that include the Cedarberg (dark, linear, north/south aligned feature in the upper right corner) and the more complex, folded Herrivierberge Mountains (dark structure, right middle) that are located northeast of Cape Town.

HIV and AIDS-related stigma in the context of family support and race in South Africa.

2010-10-01

In this paper, we describe the first phase of a research project designed to quantify the role of race and cultural identity in HIV-related stigma. The ultimate purpose is to develop an intervention that could be implemented in Black and Colored communities in Cape Town, South Africa. The PEN-3 model provided the theoretical basis for this research. A total of 397 Black and Colored participants were recruited from two communities to complete a 16-item multi-part questionnaire that was developed based on focus groups and key informant interviews. A total of 196 questionnaires were administered in Mitchell's Plain and 201 were administered in Gugulethu. Both communities are located approximately 20 km outside the city of Cape Town in an area known as the Cape Flats. Data were collected on individuals' perceptions of stigma in the contexts of the family, healthcare settings, and the community. However, only the family context is explored here. Participants were also asked to identify what they felt should be the most important area of emphasis for researchers in eliminating stigma. Similarities and differences in perceptions between Black and Colored South Africans were examined. Data were compiled on the family support domain of stigma. Though most either disagreed or were neutral, nearly equal numbers of Blacks and Coloreds thought stigma occurred in families. Blacks were also more likely than Coloreds to report experiencing stigma in their families. Both Blacks and Coloreds felt the family should be the most important focus of interventions for eliminating HIV-related stigma. Within the context of the family race, cultural values, and religious and spiritual values all contribute to HIV stigma in South Africa. Interventions should address the role of stigma within families in order to promote better HIV prevention, treatment, and care.

Human Carnivore Coexistence on Communal Land Bordering the Greater Kruger Area, South Africa

NASA Astrophysics Data System (ADS)

Lagendijk, D. D. Georgette; Gusset, Markus

2008-12-01

The aim of this study was to assess the potential for coexistence between rural people (living adjacent to a protected area) and predators (from the same area) ranging onto communal land. Ninety members of local communities bordering Manyeleti Game Reserve, which is contiguous with Kruger National Park, South Africa were interviewed. Respondents expressed diverging attitudes toward predators, which were more favorable among participants with higher education. Negative views were particularly due to fear of human and livestock losses, especially to lions, Panthera leo. Lions were thought to be the most abundant predator both within and outside the reserve. Lions were also the best known predator and were most often held responsible for killing livestock. Despite these livestock losses and a lack of conservation education, most participants voiced favorable opinions about large carnivore conservation, as predators were considered an integral part of the respondents’ natural heritage. Thanks to this cultural tolerance and also because of a largely accepted management policy regarding predator control, large carnivores and people can coexist in the vicinity of Kruger National Park.

Distribution and diversity of Russian wheat aphid (Hemiptera: Aphididae) biotypes in South Africa and Lesotho.

PubMed

Jankielsohn, Astrid

2011-10-01

Russian wheat aphid, Diuraphis noxia (Kurdjumov) (Hemiptera: Aphididae) was recorded for the first time in South Africa in 1978. In 2005, a second biotype, RWASA2, emerged, and here we report on the emergence of yet another biotype, found for the first time in 2009. The discovery of new Russian wheat aphid biotypes is a significant challenge to the wheat, Triticum aestivum L., industry in South Africa. Russian wheat aphid resistance in wheat, that offered wheat producers a long-term solution to Russian wheat aphid control, may no longer be effective in areas where the new biotypes occur. It is therefore critical to determine the diversity and extent of distribution of biotypes in South Africa to successfully deploy Russian wheat aphid resistance in wheat. Screening of 96 Russian wheat aphid clones resulted in identification of three Russian wheat aphid biotypes. Infestations of RWASA1 caused susceptible damage symptoms only in wheat entries containing the Dn3 gene. Infestations of RWASA2 caused susceptible damage symptoms in wheat entries containing Dn1, Dn2, Dn3, and Dn9 resistant genes. Based on the damage-rating scores for the seven resistance sources, a new biotype, which caused damage rating scores different from those for RWASA1 and RWASA2, was evident among the Russian wheat aphid populations tested. This new biotype is virulent to the same resistance sources as RWASA2 (Dn1, Dn2, Dn3, and Dn9), but it also has added virulence to Dn4, whereas RWASA2 is avirulent to this resistance source.

Assessing a potential solution for spatially referencing of historical aerial photography in South Africa

NASA Astrophysics Data System (ADS)

Denner, Michele; Raubenheimer, Jacobus H.

2018-05-01

Historical aerial photography has become a valuable commodity in any country, as it provides a precise record of historical land management over time. In a developing country, such as South Africa, that has undergone enormous political and social change over the last years, such photography is invaluable as it provides a clear indication of past injustices and serves as an aid to addressing post-apartheid issues such as land reform and land redistribution. National mapping organisations throughout the world have vast repositories of such historical aerial photography. In order to effectively use these datasets in today's digital environment requires that it be georeferenced to an accuracy that is suitable for the intended purpose. Using image-to-image georeferencing techniques, this research sought to determine the accuracies achievable for ortho-rectifying large volumes of historical aerial imagery, against the national standard for ortho-rectification in South Africa, using two different types of scanning equipment. The research conducted four tests using aerial photography from different time epochs over a period of sixty years, where the ortho-rectification matched each test to an already ortho-rectified mosaic of a developed area of mixed land use. The results of each test were assessed in terms of visual accuracy, spatial accuracy and conformance to the national standard for ortho-rectification in South Africa. The results showed a decrease in the overall accuracy of the image as the epoch range between the historical image and the reference image increased. Recommendations on the applications possible given the different epoch ranges and scanning equipment used are provided.

Implementation of new models of development cooperation have been on the increase lately. Coupled with this are calls for use of horizontal development cooperation mechanisms such as South-South Cooperation (SSC) as a way to enhance aid effectiveness in the health sector of developing countries. In this case series, we review recent experiences in the application of SSC initiatives to two public health situations in Africa to demonstrate the veracity of this new paradigm. Our review highlight the immense benefits associated with the use of SSC for health and provide evidence for increasing use of horizontal development coordination mechanisms to strengthen public health services delivery and socioeconomic development among African countries. Opportunities for SSC among African countries include in the areas of disease prevention and control, production of medical products and essential medicines, harmonization of regulatory processes, and health workforce development among others. However, pitfalls such as poor coordination, inadequate political commitment, lack of conducive policy environments, language barrier and inadequate financing opportunities for SSC initiatives present major dilemma for the use of SSC mechanisms. We conclude that the need for a paradigm shift from vertical to horizontal development cooperation needs no further proof but a call to action. We call on the concerned stakeholders to support the establishment of a systematic approach for use of SSC mechanisms in the health sector of Africa, designation of an African Centre of Excellence for SSC in public health and development of a regional mechanism for monitoring and evaluation of SSC initiatives in Africa.

Assuming too much? Participatory water resource governance in South Africa.

PubMed

Brown, Julia

2011-01-01

This paper argues that participation in natural resource management, which is often coupled with moves for more local ownership of decision making, is based on three sets of assumptions: about the role of the state, the universality of application of such approaches and the transformatory potential of institutional reform. The validity of these assumptions requires investigation in view of the rapid institutionalisation and scaling-up of participatory approaches, particularly in developing country contexts. Post-apartheid South Africa is widely recognised as a pioneer of participatory and devolutionary approaches, particularly in the field of water resources. It is 12 years since the promulgation of the forward-thinking 1998 National Water Act, and thus an opportune moment to reflect on South Africa's experiences of participatory governance. Drawing on empirical research covering the establishment of the first Catchment Management Agency, and the transformation of existing Irrigation Boards into more inclusive Water User Associations in the Inkomati Water Management Area, it emerges that there may be fundamental weaknesses in the participatory model and underlying assumptions, and indeed such approaches may actually reinforce inequitable outcomes: the legacy of long-established institutional frameworks and powerful actors therein continues to exert influence in post-apartheid South Africa, and has the potential to subvert the democratic and redistributive potential of the water reforms. It is argued that a reassessment of the role of the state is necessary: where there is extreme heterogeneity in challenging catchments more, rather than less, state intervention may be required to uphold the interests of marginalised groups and effect redistribution.

This study of imported cases of malaria, which was carried out in Bordeaux (France) in 1987-89, emphasizes the major part played by Plasmodium falciparum, especially in areas lying south of the Sahara in Africa, from where falciparum malaria is mainly imported to other countries. The study of these imported cases is strengthening our understanding of the epidemiology of malaria in relation to the country or area, whether the transmission occurs without interruptions or seasonally. The number of cases of P. falciparum per 1000 travellers (seen for vaccination against yellow fever at Bordeaux) gives an index for evaluating the risk of malaria. This risk changes with the epidemiological profile of falciparum malaria in the three major African ecosystems (rain forest, savannah, and sahelian belts), and is related to the progression of chloroquine resistance in Africa and influenced by the type of chemoprophylaxis proposed to travellers. The use of mefloquine for stays shorter than one month in Central Africa reduced the risk of malaria in 1988 and 1989, compared to 1987. [Editorial note. Recent data indicate some undesirable side-effects of mefloquine, e.g., its use during early pregnancy could lead to congenital defects.] Appropriate chemoprophylaxis and advice to travellers to areas lying south of the Sahara are therefore more and more necessary in order to arrest the increase in the number of imported falciparum malaria cases and reduce the number of serious cases, which are costly in terms of public health.

KwaZulu-Natal (KZN) has the highest burden of notified multidrug-resistant tuberculosis (MDR TB) and extensively drug-resistant (XDR) TB cases in South Africa. A better understanding of spatial heterogeneity in the risk of drug-resistance may help to prioritize local responses. Between July 2012 and June 2013, we conducted a two-way Lot Quality Assurance Sampling (LQAS) study to classify the burden of rifampicin (RIF)-resistant TB among incident TB cases notified within the catchment areas of seven laboratories in two northern and one southern district of KZN. Decision rules for classification of areas as having either a high- or low-risk of RIF resistant TB (based on proportion of RIF resistance among all TB cases) were based on consultation with local policy makers. We classified five areas as high-risk and two as low-risk. High-risk areas were identified in both Southern and Northern districts, with the greatest proportion of RIF resistance observed in the northernmost area, the Manguzi community situated on the Mozambique border. Our study revealed heterogeneity in the risk of RIF resistant disease among incident TB cases in KZN. This study demonstrates the potential for LQAS to detect geographic heterogeneity in areas where access to drug susceptibility testing is limited.

Travel-related risks for infectious diseases vary depending on travel patterns such as purpose, destination, and duration. In this study, we describe the patterns of travel and prescription of vaccines as well as malaria prophylaxis medication (MPM) at a travel clinic in South Korea to identify the gaps to fill for the optimization of pre-travel consultation. A cohort of travel clinic visitors in 2011 was constructed and early one-third of the visitors of each month were reviewed. During the study period, 10,009 visited the travel clinic and a retrospective chart review was performed for 3,332 cases for analysis of travel patterns and prescriptions. People receiving yellow fever vaccine (YFV) (n = 2,933) were traveling more frequently for business and tourism and less frequently for providing non-medical service or research/education compared to the 399 people who did not receive the YFV. Overall, most people were traveling to Eastern Africa, South America, and Western Africa, while South-Eastern Asia was the most common destination for the non-YFV group. Besides YFV, the typhoid vaccine was the most commonly prescribed (54.2%), while hepatitis A presented the highest coverage (74.7%) considering the natural immunity, prior and current vaccination history. Additionally, 402 (82.5%) individuals received a prescription for MPM among the 487 individuals travelling to areas with high-risk of malaria infection. Age over 55 was independently associated with receiving MPM prescription, while purpose of providing service and travel duration over 10 days were associated with no MPM prescription, despite travelling to high-risk areas. Eastern Africa and South America were common travel destinations among the visitors to a travel clinic for YFV, and most of them were travelling for tourism and business. For the individuals who are traveling to areas with high-risk for malaria, more proactive approach might be required in case of younger age travelers, longer duration, and travel purpose of providing service to minimize the risk of malaria infection.

Ticks are involved in the epidemiology of several human pathogens including spotted fever group (SFG) Rickettsia spp., Coxiella burnetii and Bartonella spp. Human diseases caused by these microorganisms have been reported from South Africa. The presence of SFG Rickettsia spp., C. burnetii and Bartonella spp. was investigated in 205 ticks collected from domestic and wild animals from Western Cape and Limpopo provinces (South Africa). Rickettsia massiliae was detected in 10 Amblyomma sylvaticum and 1 Rhipicephalus simus whereas Rickettsia africae was amplified in 7 Amblyomma hebraeum. Neither C. burnetii nor Bartonella spp. was found in the examined ticks. This study demonstrates the presence of the tick borne pathogen R. massiliae in South Africa (Western Cape and Limpopo provinces), and corroborates the presence of the African tick-bite fever agent (R. africae) in this country (Limpopo province).

Persistent organic pollutants (POPs) are a global concern due to their ubiquitous presence and toxicity. Currently, there is a lack of information regarding POPs from South Africa. Here we report and interpret concentrations of polychlorinated dibenzo-p-dioxins (PCDDs), -dibenzofurans (PCDFs) and co-planar-biphenyls (PCBs) in soils and sediments collected from central South Africa. High resolution gas chromatography-high resolution mass spectrometry (HRGC/HRMS) and the H4IIE-luc bio-assay were used to identify and quantify individual PCDD/F congeners and to report the total concentration of 2,3,7,8-tetrachloro dibenzo-p-dioxin equivalents (TCDD-EQ), respectively. TCDD-EQs determined by use of the bio-assay, and concentrations of WHO(2005)-TEQ (toxic equivalents) determined by chemical analysis, were similar. The limit of detection (LOD) for the bio-assay was 0.82 and 2.8 ng TCDD-EQ kg(-1), dw for sediment and soil, respectively. EQ20 concentrations determined by use of the bio-assay ranged from

South Africa, like the rest of Southern Africa, is ravaged by AIDS. Higher education in South Africa has a significant role to play in the fight against the spread of HIV and AIDS. This article reports the factors contributing to the spread of HIV and AIDS in three selected public universities in South Africa. To achieve the stated aim, the study answered the following research question: What are the factors contributing to the spread of HIV and AIDS in South African public universities? The problem in this study stems from South Africa's HIV and AIDS infection rate, one of the highest in the world, especially in KwaZulu-Natal. A qualitative approach was adopted by conducting focus group interviews with the students. The data were analysed using axial coding and open coding, where dominant themes from the discussions were identified and discussed in detail. The findings show that barriers to HIV and AIDS prevention, care and treatment exist in the tertiary institutions under study. Social and economic interventions are needed to stem the spread of HIV and AIDS at tertiary institutions. A range of recommendations for halting the spread of HIV and AIDS in these institutions is provided.

This article describes the activities of the Greater Johannesburg Healthy Schools Program of the World Health Organization's (WHO) Healthy Cities Project in South Africa. Healthy Cities projects emphasize community participation, intersectoral action, supportive environments for health, and a settings approach. Children in South Africa, are exposed to environmental and health hazards in the school setting including poor building design, poor equipment, and understaffing. The Healthy Schools initiative in Greater Johannesburg, is a pilot for enhancing environmental quality, health, and well-being among students. Schools include those in an informal settlement in an industrial area, an inner city district, and in a suburban area. The initiative includes research, establishment of environmental and health committees, development of an action plan, and evaluation and feedback. The plan aims to promote environmental and health sustainability, to empower children to become full participants in the community, and to support teachers and parents in the promotion of health-enhancing school environments. The program builds upon the lessons learned from several local school initiatives. Initiatives include an anti-smoking poster competition involving over 10,000 students, special environmental and health awareness days, consciousness raising among high school students about air pollution, and local efforts to engage students in environmental clean-up days.

ERTS-1 imagery as an aid to the understanding of the regional setting of base metal deposits in the North West Cape Province, South Africa. [mineral exploration

NASA Technical Reports Server (NTRS)

Viljoen, R. P.

1974-01-01

A number of base metal finds have recently focussed attention on the North Western Cape Province of South Africa as an area of great potential mineral wealth. From the point of view of competitive mineral exploration it was essential that an insight into the regional geological controls of the base metal mineralization of the area be obtained as rapidly as possible. Conventional methods of producing a suitable regional geological map were considered to be too time-consuming and ERTS-1 imagery was consequently examined. This imagery has made a significant contribution in the compilation of a suitable map on which to base further mineral exploration programmes. The time involved in the compilation of maps of this nature was found to be only a fraction of the time necessary for the production of similar maps using other methods. ERTS imagery is therefore considered to be valuable in producing accurate regional maps in areas where little or no geological data are available, or in areas of poor access. Furthermore, these images have great potential for rapidly defining the regional extent of metallogenic provinces.

Diurnal spatial distributions of aerosol optical and cloud micro-macrophysics properties in Africa based on MODIS observations

NASA Astrophysics Data System (ADS)

Ntwali, Didier; Chen, Hongbin

2018-06-01

The diurnal spatial distribution of both natural and anthropogenic aerosols, as well as liquid and ice cloud micro-macrophysics have been evaluated over Africa using Terra and Aqua MODIS collection 6 products. The variability of aerosol optical depth (AOD), Ångström exponent (AE), liquid and ice cloud microphysics (Liquid cloud effective radius LCER, Ice cloud effective radius ICER) and cloud macrophysics (Liquid cloud optical thickness LCOT, Liquid cloud water path LCWP, Ice cloud optical thickness ICOT, Ice cloud water path ICWP) parameters were investigated from the morning to afternoon over Africa from 2010 to 2014. In both the morning (Terra) and afternoon (Aqua) heavy pollution (AOD ≥ 0.6) occurs in the coastal and central areas (between 120 N-170 N and 100 E-150 E) of West of Africa (WA), Central of Africa (CA) (0.50 S-70S and 100 E-250 E),. Moderate pollution (0.3 < AOD < 0.6) often occurs in West and North of Africa (between 50 N-270 N and 160 W-50E), and clean environmental (AOD < 0.3) conditions are common in South of Africa (SA), East of Africa (EA) and some regions in North of Africa (NA). The West-North of Africa (WNA) and Central-South of Africa (CSA) regions are dominated by dust (AE < 0.7) and biomass burning (AE > 1.2) aerosols. The mixture of dust and biomass burning aerosols (0.7 < AE < 1.2) are found at the coastal areas in West of Africa (CoWA) and Central of Africa (CA) (50 N-80N and 100 E-340 E), particularly in the morning and afternoon respectively. The LCER often decrease from the morning to the afternoon in all seasons, but an increase occur from the morning to the afternoon in CSA (50 S-220 S) in DJF, both CA (20 S-50N) and CoWA in JJA and SON. The ICER increase from the morning to afternoon in all seasons over Africa and decreases in South of Africa (50 S-200 S) in DJF. The LCOT increases from the morning to afternoon in NA and SA while a decrease occur in CA in all seasons. The LCWP increase in many regions of Africa in all seasons while a decrease occurs in CoWA during JJA. The ICOT and ICWP show a remarkable increase from the morning to afternoon in regions dominated by biomass burning (CSA) compared to regions dominated by dust (WNA) aerosols in DJF, MAM and SON. Dust aerosols are mainly distributed in WNA by northerly and westerly winds in both January and April, southerly and southwesterly winds in July, and southerly and southwesterly winds in October, while biomass burning aerosols are mainly distributed in CSA by the northerly and northeasterly winds in January, easterly winds in April, July and October. The diurnal variability of cloud parameters is associated with both convective processes and cloud types. The knowledge of interactions between natural and anthropogenic aerosols with liquid and ice cloud microphysics parameters could contribute to improve aerosol and cloud remote sensing retrieval.

This paper arises from a four-country study that sought to better understand the drivers of skilled health worker migration, its consequences, and the strategies countries have employed to mitigate negative impacts. The four countries-Jamaica, India, the Philippines, and South Africa-have historically been "sources" of skilled health workers (SHWs) migrating to other countries. This paper presents the findings from South Africa. The study began with a scoping review of the literature on health worker migration from South Africa, followed by empirical data collected from skilled health workers and stakeholders. Surveys were conducted with physicians, nurses, pharmacists, and dentists. Interviews were conducted with key informants representing educators, regulators, national and local governments, private and public sector health facilities, recruitment agencies, and professional associations and councils. Survey data were analyzed using descriptive statistics and regression models. Interview data were analyzed thematically. There has been an overall decrease in out-migration of skilled health workers from South Africa since the early 2000s largely attributed to a reduced need for foreign-trained skilled health workers in destination countries, limitations on recruitment, and tighter migration rules. Low levels of worker satisfaction persist, although the Occupation Specific Dispensation (OSD) policy (2007), which increased wages for health workers, has been described as critical in retaining South African nurses. Return migration was reportedly a common occurrence. The consequences attributed to SHW migration are mixed, but shortages appear to have declined. Most promising initiatives are those designed to reinforce the South African health system and undertaken within South Africa itself. In the near past, South Africa's health worker shortages as a result of emigration were viewed as significant and harmful. Currently, domestic policies to improve health care and the health workforce including innovations such as new skilled health worker cadres and OSD policies appear to have served to decrease SHW shortages to some extent. Decreased global demand for health workers and indications that South African SHWs primarily use migratory routes for professional development suggest that health worker shortages as a result of permanent migration no longer pertains to South Africa.

Comparative analysis of plant use in peri-urban domestic gardens of the Limpopo Province, South Africa

PubMed Central

2014-01-01

Background Relatively little has been researched or published on the importance of peri-urban domestic gardens as part of a household livelihood strategy in South Africa. Due to lack of comprehensive data on peri-urban domestic gardens, their potential value as luxury green space, provision of food, income and ecosystem services to the fast growing urban population in South Africa is not clearly known. The aim of this study was to document differences and similarities in plant use and diversity in domestic gardens of two peri-urban communities in the Limpopo Province that differ in proximity to an urban area. Methods Data on plant use categories of 62 domestic gardens in the peri-urban areas of the Limpopo Province were collected in Seshego and Lebowakgomo. Semi-structured interviews, observation and guided field walks with 62 participants were employed between May and October 2012. Results A total of 126 plant species were recorded for both Seshego and Lebowakgomo. Domestic gardens in the more remote areas of Lebowakgomo were characterized by higher percentage of food plants (47 species, 83.8% of the total food plants recorded) and medicinal plants (31 species, 83.7%). Lebowakgomo domestic gardens were also characterized by higher numbers of indigenous plants (76.7%) showing similarities to the natural surrounding vegetation in terms of plant species. On the contrary, domestic gardens of Seshego on the periphery of the city centre were characterized by higher percentage of exotic species (81.8%) and ornamental plants (73%), with food plants playing a supplementary role. Comparison of the two areas demonstrated a remarkable difference in plant use and composition. Conclusions This study revealed that there are differences in utilization of plant resources between households on the edge of an urban centre and those in the more remote areas. Food and medicinal plants play an important role in remote areas; while ornamental plants play an important role in urban domestic gardens. But the collective desire for food, medicinal and ornamental plants by both communities on the edge of an urban centre and those in the more remote areas highlight the importance of plant resources in domestic gardens.

The objective of the study was to compare the frequency of consumption of cariogenic food items among 4-month-old to 24-month-old children in two neighbouring rural areas in KwaZulu-Natal Province, South Africa: Nyuswa/Embo (Area A) (n = 127) and Ndunakazi (Area B) (n = 105). Dietary intake was assessed using a food frequency questionnaire. Mothers or caregivers were interviewed by a team of Zulu-speaking fieldworkers. The percentage of children consuming the individual food items (consumers) and the weekly consumption for consumers were calculated for the two areas separately. The food items were ranked in descending order according to the combined group of children and reported for each area within five selected food groups (carbohydrates, sugars, fruit and vegetables, milk and milk products, and other foods and snacks). Food items were 'flagged' according to their cariogenic potential. Fisher's exact test on absolute numbers tested for significant differences in the frequency of intake between individual food items between the two groups. Significance was set at P < 0.05. The frequency of consumption of certain listed cariogenic food items showed significant differences between the two areas. A higher percentage of children in Area A than in Area B consumed most of the food items and also more frequently. Children mainly consumed foods with a cariogenic score of 2, solid foods with 8-20% sugars as well as foods high in starch with less than 10% sugars. This knowledge is essential to gain insight into the eating pattern among rural communities and will provide a baseline for developing and adapting dietary advice specifically for young rural South African children with particular emphasis on the prevention of dental caries.

Stratigraphy of the pedogenic manganese nodules in the Carletonville area, North West Province of South Africa: A case study of the General Nice Manganese Mine

NASA Astrophysics Data System (ADS)

Pharoe, Benedict Kinshasa; Liu, Kuiwu

2018-07-01

The lithostratigraphy of pedogenic manganese (Mn) nodules in the Carletonville area is similar to the Klipkuil, Ryedale, Wes Wits, and Houtkoppies deposits in the West Rand region of the Gauteng and North West Provinces and to a lesser extent the Bronkhorstfontein manganese deposit in the Limpopo Province of South Africa. The lithostratigraphy of the ore deposit at the General Nice Manganese Mine consists of a basal manganese wad, preserved in a typical karst setting on top of the underlying Malmani stromatolitic dolomites and Tertiary fluvial and secondary mineral deposits consisting of manganese nodules of variable size in a finer-grained soil matrix. At the top of the deposit is a Mn-depleted Quaternary sand cover. The Tertiary alluvial succession hosting Mn nodules was informally subdivided into A, B, C, D, E, F, G and H zones on the basis of geochemical analyses (XRD, XRF and SEM) of bulk zone samples and the manganese nodule size and concentration.

Monitoring the extent and occurrence of fire in the different veld types of South Africa with particular reference to its ecological role and role in range management

The author has identified the following significant results. Veld burning was recorded from LANDSAT imagery covering approximately 75 million ha or 62% of the surface of the eastern part of South Africa. All basic data on the location, areas, and numbers of burns for 10 biomes, composed of 67 veld types, are available on 1:250,000 and 1:500,000 map overlays, and are summarized on small scale maps showing fire distribution and amount burned in classes per 15 minute square of latitude and longitude. Veld burning is not randomly distributed, but is almost continuous over a broad belt, widest in the north and narrowing southeastwards, and then southwestwards between the eastern escarpment and the area. It is shown that over almost the whole sea, the overall pattern of veld burning is clearly marked out as early as July in midwinter, subsequent development being merely an intensification of the pattern.

The database documented in this numeric data package, a revision to a database originally published by the Carbon Dioxide Information Analysis Center (CDIAC) in 1995, consists of annual estimates, from 1850 through 1990, of the net flux of carbon between terrestrial ecosystems and the atmosphere resulting from deliberate changes in land cover and land use, especially forest clearing for agriculture and the harvest of wood for wood products or energy. The data are provided on a year-by-year basis for nine regions (North America, South and Central America, Europe, North Africa and the Middle East, Tropical Africa, the Former Soviet Union, China, South and Southeast Asia, and the Pacific Developed Region) and the globe. Some data begin earlier than 1850 (e.g., for six regions, areas of different ecosystems are provided for the year 1700) or extend beyond 1990 (e.g., fuelwood harvest in South and Southeast Asia, by forest type, is provided through 1995). The global net flux during the period 1850 to 1990 was 124 Pg of carbon (1 petagram = 1015 grams). During this period, the greatest regional flux was from South and Southeast Asia (39 Pg of carbon), while the smallest regional flux was from North Africa and the Middle East (3 Pg of carbon). For the year 1990, the global total net flux was estimated to be 2.1 Pg of carbon.

Social accountability and nursing education in South Africa.

PubMed

Armstrong, Susan J; Rispel, Laetitia C

2015-01-01

There is global emphasis on transforming health workforce education in support of universal health coverage. This paper uses a social accountability framework, specifically the World Health Organization's six building blocks for transformative education, to explore key informants' perspectives on nursing education in South Africa. Using a snowballing sampling technique, 44 key informants were selected purposively on the basis of their expertise or knowledge of the research area. Semi-structured interviews were conducted with the key informants after informed consent had been obtained. The interviews were analysed using template analysis. South Africa has strategic plans on human resources for health and nursing education, training, and practice and has a well-established system of regulation and accreditation of nursing education through the South African Nursing Council (SANC). Key informants criticised the following: the lack of national staffing norms; sub-optimal governance by both the SANC and the Department of Health; outdated curricula that are unresponsive to population and health system needs; lack of preparedness of nurse educators; and the unsuitability of the majority of nursing students. These problems are exacerbated by a perceived lack of prioritisation of nursing, resource constraints in both the nursing education institutions and the health training facilities, and general implementation inertia. Social accountability, which is an essential component of transformative education, necessitates that attention be paid to the issues of governance, responsive curricula, educator preparedness, and appropriate student recruitment and selection.

A roaring trade? The legal trade in Panthera leo bones from Africa to East-Southeast Asia

PubMed Central

Loveridge, Andrew J.; Newton, David J.; Macdonald, David W.

2017-01-01

The African lion is the only big cat listed on CITES Appendix II, and the only one for which international commercial trade is legal under CITES. The trade in lion body parts, and especially the contentious trade in bones from South Africa to Asia, has raised concerns spanning continents and cultures. Debates were amplified at the 2016 CITES Conference of the Parties (CoP17) when a proposal to up-list lions to Appendix I was not supported and a compromise to keep them on Appendix II, with a bone trade quota for South Africa, was reached instead. CoP17 underscored a need for further information on the lion bone trade and the consequences for lions across the continent. Legal international trade in bones to Asia, allegedly to supply the substitute ‘tiger bone’ market, began in South Africa in February 2008 when the first CITES permits were issued. It was initially unclear the degree to which bones were sourced from captive-origin lions, and whether trade was a threat to wild lion populations. Our original assessment of the legal CITES-permitted lion bone trade from South Africa to East-Southeast Asia was for the period 2008–2011 (published 2015). In this paper, we consolidate new information that has become available for 2012–2016, including CITES reports from other African countries, and data on actual exports for three years to 2016 supplied by a freight forwarding company. Thus, we update the figures on the legal trade in lion bones from Africa to East-Southeast Asia in the period 2008–2016. We also contextualise the basis for global concerns by reviewing the history of the trade and its relation to tigers, poaching and wildlife trafficking. CITES permits issued to export bones escalated from ±314y-1 skeletons from 2008–2011, to ±1312y-1 skeletons from 2013–2015. South Africa was the only legal exporter of bones to Asia until 2013 when Namibia issued permits to export skeletons to Vietnam. While CITES permits to export ±5363 skeletons from Africa to Asia from 2008–2015 were issued (99.1% from South Africa; 0.7% from Namibia) (51% for Laos), actual exports were less than stated on the permits. However, information on actual exports from 2014–2016 indicated that >3400 skeletons were exported in that period. In total, >6000 skeletons weighing no less than 70 tonnes have been shipped to East-Southeast Asia since 2008. Since few wild lions are hunted and poached within South African protected areas, skeletons for the legal trade appear to be derived from captive bred lions. However, confirmation of a 116kg shipment from Uganda to Laos, and reports of lion poaching in neighbouring countries, indicate that urgent proactive monitoring and evaluation of the legal and illegal trade is necessary in African lion range states where vulnerable wild lion populations are likely to be adversely affected.

Risk to tourists posed by wild mammals in South Africa.

PubMed

Durrheim, D N; Leggat, P A

1999-09-01

One of South Africa's principal tourist attractions is the opportunity to encounter Africa's large mammals in the wild. Attacks by these mammals can be exceptionally newsworthy with potentially deleterious effects on tourism. Little is known about the risk of injury and death caused by wild mammals to visitors to South Africa's nature reserves. The aim of this study was to determine the incidence of fatal and nonfatal attacks on tourists by wild mammals in South Africa and to ascertain avoidable factors, if any. Commercial press records covering all South African Newspapers archived at the Independent Newspapers' central library were systematically reviewed for a 10-year period, January 1988 to December 1997 inclusive, to identify all deaths and injuries to domestic and international tourists resulting from encounters with wild mammals in South Africa. All of these incidents were analyzed to ascertain avoidable factors. During the review period seven tourists, including two students from Thailand and a German traveler, were killed by wild mammals in South Africa. Three of the four deaths ascribed to lions resulted from tourists carelessly approaching prides on foot in lion reserves. A judicial inquiry found that the management of a KwaZulu-Natal Reserve was culpable for the remaining death. Tourist ignorance of animal behavior and flagrant disregard of rules contributed to the two fatalities involving hippopotami. The unusual behavior manifested by the bull elephant responsible for the final death, resulted from discomfort caused by a dental problem to this pachyderm. During the same period there were 14 nonfatal attacks on tourists, including five by hippo, three by buffalo, two by rhino, and one each by a lion, leopard, zebra and musth elephant. Only the latter occurred while the visitor was in a motor vehicle. Tourist ethological naivete and failure to determine the experience of trail guides prior to travel, resulted in inadvertent agonistic behavior, unnecessary risk-taking and avoidable injury. This retrospective study has shown that attacks on tourists by wild mammals in South Africa are an uncommon cause of injury and death. Sensible precautions to minimize this risk include remaining in a secure motor vehicle or adequately fenced precincts while in the vicinity of large mammals, rigidly observing nature reserve instructions, never approaching animals that appear ill, malnourished, displaying aggressive behavior traits or female wild mammals with young, and demanding adequately trained and experienced game rangers when embarking on walking trails. Any behavior that might be construed as antagonistic and which could provoke an attack by large mammals should be avoided (e.g., driving directly at a lion). Visitors need to be informed of classic signs of aggression, in particular in elephants, which will allow timely avoidance measures to be taken. The risk-enhancing effect of excessive alcohol intake is undesirable in the game reserve setting, as is driving at high speed after dusk in areas where hippos graze. Local advice on personal safety in wildlife reserves and the credentials of trail guides should be obtained from lodge or reserve management, tourism authorities or the travel industry prior to travel to game reserves.

The stone huntsman spider genus Eusparassus (Araneae: Sparassidae): systematics and zoogeography with revision of the African and Arabian species.

PubMed

Moradmand, Majid

2013-01-01

An overview on the systematics of the stone huntsman spider genus Eusparassus Simon, 1903 and an identification key to the known species are presented. Six species-groups are proposed: the walckenaeri group (3 species, Eastern Mediterranean to Arabia and parts of North-Eastern Africa), dufouri group (8 species, Iberian Peninsula to parts of North-western Africa), vestigator group (3 species, Central to Eastern Africa and an isolated area in India), jaegeri group (4 species, Southern and South-Eastern Africa), tuckeri group (2 species, South-Western Africa) and doriae group (7 species, Middle East to Central and South Asia). Two species, E. pontii Caporiacco, 1935 and E. xerxes (Pocock, 1901) could not be placed in any of the above groups. The species from Africa and Arabia are revised. The following ten species are re-described: Eusparassus barbarus (Lucas, 1846), E. atlanticus Simon, 1909 stat. nov., E. syrticus Simon, 1909, E. oraniensis (Lucas, 1846), E. letourneuxi (Simon, 1874), E. fritschi (Koch, 1873) stat. rev., E. walckenaeri (Audouin, 1826), E. vestigator (Simon, 1897) comb. nov., E. laevatus (Simon, 1897) comb. nov. and E. tuckeri (Lawrence, 1927) comb. nov. The latter three species are transferred from Olios Walckenaer, 1837. Seven new species are described: Eusparassus arabicus spec. nov. (male, female) from Arabian Peninsula, E. educatus spec. nov. (male, female) from Namibia, E. reverentia spec. nov. (male, female) from Burkina Faso and Nigeria, E. jaegeri spec. nov. (male, female) from South Africa and Botswana, E. jocquei spec. nov. (male, female) from Zimbabwe, E. borakalalo spec. nov. (female) from South Africa and E. schoem-anae spec. nov. (male, female) from South Africa and Namibia. Three taxa, E. dufouri maximus Strand, 1906 syn. nov., E. rufobrunneus Caporiacco, 1941 syn. nov. and Olios furcatus Lawrence, 1927 syn. nov. are proposed as junior syn-onyms of E. oraniensis, E. vestigator comb. nov. and E. tuckeri comb. nov. respectively. Males of E. atlanticus stat. nov. and E. fritschi stat. rev. are described for the first time as in the female of E. vestigator comb. nov. Neotypes are desig-nated for E. barbarus, E. oraniensis and E. letourneuxi (all from Algeria). The male and female of Cercetius perezi Simon, 1902, which was known only from the immature holotype, are described here for the first time. This resulted in recogniz-ing the monotypic and little used generic name Cercetius Simon, 1902 as a synonym of the widely used name Eusparas-sus. Nearly all the species are illustrated for the first time. Eusparassus concolor Caporiacco, 1939 is transferred to Olios and the replacement name Olios quesitio is proposed because of secondary homonymy. For the majority of the species, new geographical records are presented. The systematics and zoogeography of the currently known species and species groups are discussed. A brief note on the copulation process of E. walckenaeri is presented.

Policy implementation in wheelchair service delivery in a rural South African setting.

2013-01-01

Wheelchairs allow users to realise basic human rights and improved quality of life. South African and international documents guide rehabilitation service delivery and thus the provision of wheelchairs. Evidence indicates that rehabilitation policy implementation gaps exist in rural South Africa. The aim of this article was to explore the extent to which wheelchair service delivery in a rural, remote area of South Africa was aligned with the South African National Guidelines on Provision of Assistive Devices, The United Nations Convention on the Rights of Persons with Disabilities and The World Health Organization Guidelines on Provision of Wheelchairs in Less-Resourced Settings. Qualitative methods were used. Data were collected through semi-structured interviews with 22 participants who were identified through purposive sampling. Content analysis of data was preformed around the construct of wheelchair service delivery. Study findings identified gaps between the guiding documents and wheelchair service delivery. Areas where gaps were identified included service aspects such as referral, assessment, prescription, user and provider training, follow up, maintenance and repair as well as management aspects such as staff support, budget and monitoring. Positive findings related to individual assessments, enthusiastic and caring staff and the provision of wheelchairs at no cost. The gaps in policy implementation can have a negative impact on users and the service provider. Inappropriate or no wheelchairs limit user function, participation and quality of life. In addition, an inappropriate wheelchair will have a shorter lifespan, requiring frequent repairs and replacements with cost implications for the service provider.

The aim of this prospective, questionnaire-based study is to assess pre-travel vaccinations for international travellers who receive pre-travel advice in Greece. A total of 2494 travellers were studied from January 1, 2009 through December 31, 2010. Travellers sought pre-travel advice at a median of 16 days (range: 0-349 days) before departure. Sub-Saharan Africa was the most common destination (34.7%). Most travellers (60.8%) travelled for <1 month, for recreation purposes (58.9%), stayed in hotels (65.3%), and in urban areas (53.6%). Yellow fever, tetravalent meningococcal, typhoid fever, cholera, and rabies vaccines were administered to 1629 (65.3%), 666 (26.7%), 615 (24.7%), 28 (1.1%), and/or 12 (0.5%) travellers, respectively. Of those who received Yellow fever vaccine, 737 (45.2%) travelled to sub-Saharan Africa, 332 (20.4%) travelled to South America, 949 (58.3%) stayed for short term, and 762 (46.8%) stayed in urban areas. Of the 1629 travellers vaccinated against Yellow fever, 150 (9.2%) and 226 (13.8%) travelled to areas of sub-Saharan Africa and South America respectively, where the vaccine is not or generally not recommended. Of those travellers who received meningococcal vaccine, 327 (49.1%) travelled to the Middle East for the Hajj, 251 (29%) travelled to sub-Saharan Africa, 410 (61.6%) for short term, and 540 (64.4%) stayed in urban areas. Of those travellers who received typhoid vaccine, 241 (39.2%) travelled to sub-Saharan Africa, 78 (12.7%) to the Indian subcontinent, 234 (38%) for short term, and 419 (68.1%) stayed in urban areas. Regarding routine vaccines, tetanus-diphtheria, poliomyelitis, and measles-mumps-rubella vaccines were administered to 707 (28.3%), 639 (25.6%) and/or 149 (6%) travellers, respectively. Of those to whom poliomyelitis vaccine was recommended, 295 (46.2%) and 137 (21.4%) travelled to sub-Saharan Africa and the Middle East, respectively, and 362 (56.7%) travelled for short term. In conclusion, this study revealed that there is a need for more selective vaccine recommendations for travellers to developing countries, taking under consideration travellers and travel characteristics as well. Strategies to target travel health consultants should be developed in order to increase awareness in travel health issues. Copyright © 2012 Elsevier Ltd. All rights reserved.

The 7th African Rotavirus Symposium was held in Cape Town, South Africa, on the 8th November 2012 as a Satellite Symposium at the First International African Vaccinology Conference. Over 150 delegates participated in this symposium including scientists, clinicians, health officials, policymakers and vaccine manufacturers from across Africa. Key topics discussed included rotavirus surveillance, rotavirus vaccine introduction, post rotavirus vaccine impact analysis and intussusception data and surveillance in Africa. The symposium provided early rotavirus vaccine adopter countries in Africa (South Africa, Ghana and Botswana) an opportunity to share up-to-date information on vaccine introduction, and allowed colleagues to share experiences in establishing routine rotavirus surveillance (Tanzania, Niger and Rwanda). Overall, the symposium highlighted the high burden of rotavirus in Africa, and the need to continue to strengthen efforts in preventing rotavirus diarrhoea in Africa. Copyright © 2014.

Africa's middle class women bring entrepreneurial opportunities in breast care medical tourism to South Africa.

PubMed

Ahwireng-Obeng, Frederick; van Loggerenberg, Charl

2011-01-01

Africa's distribution of specialized private health services is severely disproportionate. Mismatch between South Africa's excess supply and a huge demand potential in an under-serviced continent represents an entrepreneurial opportunity to attract patients to South Africa for treatment and recuperative holidays. However, effective demand for intra-African medical tourism could be constrained by sub-Saharan poverty. Results from interviewing 320 patients and five staff at the Johannesburg Breast care Centre of Excellence, however, reject this proposition, Africa's middle class women being the target market estimated to grow annually by one million while breast cancer incidence increases with middle-class lifestyles. Uncovering this potential involves an extensive marketing strategy. Copyright © 2010 John Wiley & Sons, Ltd.

The aim of this work is to characterize the isotope composition of water (2H and 18O) in order to establish the relationship between fractured and detritic aquifers in similar hydrological environments located at both sides of the Atlantic Ocean. The Mar del Plata zone, placed in the Argentine Buenos Aires province in South America, and the Rawsonville and Sandspruit river catchment areas, situated in the Western Cape province in South Africa were compared. Rainwater and groundwater samples from fractured and detritic aquifers were analyzed through laser spectroscopy. In both Argentina and South African study sites, stable isotopes data demonstrate an aquifers recharge source from rainfall. For the Mar del Plata region, two different groups of detritic aquifer's samples with distinct recharge processes can be identified due to the close relationship existing between the present hydrogeological environments, the aquifer's grain size sediments and the isotopes contents: one representing rapid infiltration in aquifer sediments of the creeks' palaeobeds and hills zones (sandy or silt sandy sediments) and the other with slow infiltration of evaporated water in plain zones with an aquitard behavior. In the last group, the evaporation process occurs previous infiltration or in the aquifer's non-saturated zone, because of the existence of very low topographic gradients and fine-grained sediments. The evaporation phenomenon is not evident in the Sandspruit river catchment site's detritic aquifer, because its sandy composition allows a faster infiltration rate than in the loess that compounds the Pampeano aquifer in the interfluves zones of the Argentinian study area.

The medial Permian (~270-260 Ma: Guadalupian) was a time of important tetrapod faunal changes, in particular reflecting a turnover from pelycosaurian- to therapsid-grade synapsids. Until now, most knowledge on tetrapod distribution during the medial Permian has come from fossils found in the South African Karoo and the Russian Platform, whereas other areas of Pangaea are still poorly known. We present evidence for the presence of a terrestrial carnivorous vertebrate from the Middle Permian of South America based on a complete skull. Pampaphoneus biccai gen. et sp. nov. was a dinocephalian "mammal-like reptile" member of the Anteosauridae, an early therapsid predator clade known only from the Middle Permian of Russia, Kazakhstan, China, and South Africa. The genus is characterized, among other features, by postorbital bosses, short, bulbous postcanines, and strongly recurved canines. Phylogenetic analysis indicates that the Brazilian dinocephalian occupies a middle position within the Anteosauridae, reinforcing the model of a global distribution for therapsids as early as the Guadalupian. The close phylogenetic relationship of the Brazilian species to dinocephalians from South Africa and the Russian Platform suggests a closer faunistic relationship between South America and eastern Europe than previously thought, lending support to a Pangaea B-type continental reconstruction.

South Africa is in the midst of a devastating HIV-AIDS epidemic and most new HIV infections occur among young adults and adolescents. The current study examined risk behaviors and HIV risk factors among young people living in a Black South African township. Using community-based outreach methods of street intercept and facility-based surveying, 113 men and 115 women age 25 and younger responded to an anonymous survey. Results showed that men (68%) and women (56%) reported HIV-related high risk sexual behaviors. Although knowledge about HIV transmission was generally high, there was evidence that misconceptions about AIDS persist, particularly myths related to HIV transmission. For young men, HIV risk factors were associated with fewer years of education, lower levels of AIDS-related knowledge, condom attitudes, and Dagga (marijuana) use. Among young women, HIV risk factors were associated with beliefs that condoms get in the way of sex and rates of unprotected vaginal intercourse. Despite adequate general AIDS knowledge and risk sensitization, South African youth demonstrated high rates of sexual practices that place them at risk for HIV infection. There is an urgent need for behavioral interventions targeted to young South Africans living in the most economically disadvantaged areas.

Plate rigidity is one of the main paradigms of plate tectonics and a fundamental assumption in the definition of a global reference frame as ITRF. Although still far for optimal, the increased GPS instrumentation of the African region can allow us to understand how rigid one of the major plate can be. The presence of diffused band of seismicity, the Cameroon volcanic line, Pan African Kalahari orogenic belt and East Africa Rift suggest the possibility of relative motion among the different regions within the Nubia. The study focuses on the rigidity of Nubia plate. We divide the plate into three regions: Western (West Africa craton plus Nigeria), Central (approximately the region of the Congo craton) and Southern (Kalahari craton plus South Africa) and we utilize Euler Vector formulation to study internal rigidity and eventual relative motion. Developing five different reference frames with different combinations of the 3 regions, we try to understand the presence of the relative motion between the 3 cratons thus the stability of the Nubia plate as a whole. All available GPS stations from the regions are used separately or combined in creation of the reference frames. We utilize continuous stations with at least 2.5 years of data between 1994 and 2014. Given the small relative velocity, it is important to eliminate eventual biases in the analysis and to have a good estimation in the uncertainties of the observed velocities. For this reason we perform our analysis using both Bernese and Gipsy-oasis codes to generate time series for each station. Velocities and relative uncertainties are analyzed using the Allan variance of rate technique, taking in account for colored noise. An analysis of the color of the noise as function of latitude and climatic region is also performed to each time series. Preliminary results indicate a slight counter clockwise motion of West Africa craton with respect to South Africa Kalahari, and South Africa Kalahari-Congo Cratons. In addition, a possible counter clockwise rotation of the South African Kalahari craton with respect to the Nubian plate caused by southward propagation of the East Africa Rift is compatible with the observations. However, the results are at the limit of the statistical significance and within the current velocity uncertainties the Nubia plate appears as single- rigid plate.

Background Mental disorders are a major contributor to the burden of disease in all regions of the world. There are limited data on the epidemiology of major depressive disorder in South Africa. Methods A nationally representative household survey was conducted between 2002 and 2004 using the World Health Organization Composite International Diagnostic Interview (CIDI) to establish a diagnosis of depression. The dataset analysed included 4 351 adult South Africans of all racial groups. Results The prevalence of major depression was 9.7% for lifetime and 4.9% for the 12 months prior to the interview. The prevalence of depression was significantly higher among females than among males. The prevalence was also higher among those with a low level of education. Over 90% of all respondents with depression reported global role impairment. Conclusion In comparison with data from other countries, South Africa has lower rates of depression than the USA but higher rates than Nigeria. The findings are broadly consistent with previous findings in South Africa. These findings are the first step in documenting a level of need for care in a context of significant under-funding of mental health services and research in South Africa PMID:19588800

Balancing Economic and other Discourses in the Internationalization of Higher Education in South Africa

Since the end of the apartheid era in South Africa, "internationalization" of higher education has been a popular theme as the country takes its place as a regional leader in education and research in sub-Saharan Africa. However, competing discourses of internationalization have produced economic and moral dilemmas rather than the realization of philanthropic academic aims. The process of internationalizing higher education in South Africa has been greatly compromised by under-funding and over-crowding of post-secondary education institutions in the country.

A genotype 2 lyssavirus, Lagos bat virus (LBV), was isolated from a terrestrial wildlife species (water mongoose) in August 2004 in the Durban area of the KwaZulu-Natal Province of South Africa. The virus isolate was confirmed as LBV by antigenic and genetic characterization, and the mongoose was identified as Atilax paludinosus by mitochondrial cytochrome b sequence analysis. Phylogenetic analysis demonstrated sequence homology with previous LBV isolates from South African bats. Studies performed in mice indicated that the peripheral pathogenicity of LBV had been underestimated in previous studies. Surveillance strategies for LBV in Africa must be improved to better understand the epidemiology of this virus and to make informed decisions on future vaccine strategies because evidence is insufficent that current rabies vaccines provide protection against LBV.

A newly revised atlas of Africa features more than 300 satellite images that show striking before and after photographs of environmental changes spanning about 35 years. Africa: Atlas of Our Changing Environment, compiled by the United Nations Environment Programme (UNEP), provides visual evidence of how development choices, population growth, climate change, and, in some cases, conflicts affect Africa, often negatively. The book includes photographs of shrinking glaciers on Mount Kilimanjaro as well as on Uganda's Rwenzori Mountains; deforestation along an expanding road system in the Congo; the drying up of Lake Chad; and the expansion of urban areas such as Cape Town, South Africa, and Dakar, Senegal. Satellite images also indicate some positive signs of environmental management, including action to stop overgrazing in a Tunisian national park, the effects of a management plan for a dam in Zambia that has helped restore seasonal flooding, and positive impacts of wetlands expansion around a national park in Mauritania.

Introduction Given the burden of road traffic injuries (RTIs) in South Africa, economic evaluations of prevention interventions are necessary for informing and prioritising public health planning and policy with regard to road safety. Methods In view of the dearth of RTI cost analysis, and in order to understand the extent to which RTI-related costs in South Africa compare with those in other low- and middle-income countries (LMICs), we reviewed published economic evaluations of RTI-related prevention in LMICs. Results Thirteen articles were identified, including cost-of-illness and cost-effectiveness studies. Although RTI-related risk factors in South Africa are well described, costing studies are limited. There is minimal information, most of which is not recent, with nothing at all on societal costs. Cost-effective interventions for RTIs in LMICs include bicycle and motorcycle helmet enforcement, traffic enforcement, and the construction of speed bumps. Discussion Policy recommendations from studies conducted in LMICs suggest a number of cost-effective interventions for consideration in South Africa. They include speed bumps for pedestrian safety, strategically positioned speed cameras, traffic enforcement such as the monitoring of seatbelt use, and breathalyzer interventions. However, interventions introduced in South Africa will need to be based either on South African cost-effectiveness data or on findings adapted from similar middle-income country settings.

South Africa has nominated Astronomy as a “flagship science” and aims to be an international Astronomy hub through projects such as the Square Kilometre Array (SKA) and the South African Large Telescope (SALT). These projects open up career opportunities in maths, science and engineering and therefore offers a very real door for learners to enter into careers in science and technology through Astronomy. However, the Trends in International Mathematics and Science Survey (TIMSS), the Global Competitiveness Report (GCR) and Annual National Assessment (ANA) have highlighted that South Africa’s Science and Mathematics education is in a critical condition and that South African learners score amongst the worst in the world in both these subjects. In South Africa Astronomy is generally regarded as the worst taught and most avoided Natural Science knowledge strand, and most teachers that specialised in Natural Sciences, never covered Astronomy in their training.In order to address these issues a collaborative project between the University of South Africa (UNISA) and the Hartebeesthoek Radio Astronomy Observatory (HartRAO) was initiated, which aims to assist teachers to gain more knowledge and skills so that they can teach Astronomy with confidence. By collaborating we aim to ensure that the level of astronomy development will be raised in both South Africa and the rest of Africa.With the focus on Teaching and Learning, the research was conducted within a quantitative paradigm and 600 structured questionnaires were administered to Natural Science teachers in Public primary schools in Gauteng, South Africa. This paper reports the findings of this research and makes recommendations on how to assist teachers to teach Astronomy with confidence.

The effects of trypanosomiasis on rural economy*

Trypanosomiasis, both of humans and of livestock, is one of the most important factors restricting economic development in Africa today. The present paper outlines how this disease is limiting agricultural, veterinary and forestry development in the Sudan, Bechuanaland and West Africa. The present tsetse-fly distribution is reviewed. Glossina palpalis and G. morsitans occur in the south Sudan and G. morsitans in the Ngamiland district of Bechuanaland; G. morsitans, G. palpalis and G. tachinoides are the most important species in West Africa. These tsetse flies have altered the cattle distribution in all three regions and, in addition to causing widespread disease, have created local overstocking problems in the tsetse-free grazing areas, and have enforced nomadism on breeding herds and economic loss in slaughter cattle along the trade cattle routes in West Africa. Human trypanosomiasis is not now such an urgent problem and public health measures have led to its control in all three areas. Increased agricultural development, which can be a successful and economic method of reclaiming land from tsetse flies, must be intensified in all three areas. Forest conservation policy comes into conflict with tsetse control measures only in West Africa. Detailed tsetse-fly surveys and research, on which future plans can be firmly based, are now urgently required. ImagesFIG. 6 PMID:14001093

Phytoliths as an indicator of early modern humans plant gathering strategies, fire fuel and site occupation intensity during the Middle Stone Age at Pinnacle Point 5-6 (south coast, South Africa)

The study of plant remains in archaeological sites, along with a better understanding of the use of plants by prehistoric populations, can help us shed light on changes in survival strategies of hunter-gatherers and consequent impacts on modern human cognition, social organization, and technology. The archaeological locality of Pinnacle Point (Mossel Bay, South Africa) includes a series of coastal caves, rock-shelters, and open-air sites with human occupations spanning the Acheulian through Middle Stone Age (MSA) and Later Stone Age (LSA). These sites have provided some of the earliest evidence for complex human behaviour and technology during the MSA. We used phytoliths—amorphous silica particles that are deposited in cells of plants—as a proxy for the reconstruction of past human plant foraging strategies on the south coast of South Africa during the Middle and Late Pleistocene, emphasizing the use and control of fire as well as other possible plant uses. We analysed sediment samples from the different occupation periods at the rock shelter Pinnacle Point 5–6 North (PP5-6N). We also present an overview of the taphonomic processes affecting phytolith preservation in this site that will be critical to conduct a more reliable interpretation of the original plant use in the rock shelter. Our study reports the first evidence of the intentional gathering and introduction into living areas of plants from the Restionaceae family by MSA hunter-gatherers inhabiting the south coast of South Africa. We suggest that humans inhabiting Pinnacle Point during short-term occupation events during Marine Isotope Stage (MIS) 5 built fast fires using mainly grasses with some wood from trees and/or shrubs for specific purposes, perhaps for shellfish cooking. With the onset of MIS 4 we observed a change in the plant gathering strategies towards the intentional and intensive exploitation of dry wood to improve, we hypothesise, combustion for heating silcrete. This human behaviour is associated with changes in stone tool technology, site occupation intensity and climate change. PMID:29864147

2015-12-01

We compiled all credible repeated lion surveys and present time series data for 47 lion (Panthera leo) populations. We used a Bayesian state space model to estimate growth rate-λ for each population and summed these into three regional sets to provide conservation-relevant estimates of trends since 1990. We found a striking geographical pattern: African lion populations are declining everywhere, except in four southern countries (Botswana, Namibia, South Africa, and Zimbabwe). Population models indicate a 67% chance that lions in West and Central Africa decline by one-half, while estimating a 37% chance that lions in East Africa also decline by one-half over two decades. We recommend separate regional assessments of the lion in the World Conservation Union (IUCN) Red List of Threatened Species: already recognized as critically endangered in West Africa, our analysis supports listing as regionally endangered in Central and East Africa and least concern in southern Africa. Almost all lion populations that historically exceeded ∼ 500 individuals are declining, but lion conservation is successful in southern Africa, in part because of the proliferation of reintroduced lions in small, fenced, intensively managed, and funded reserves. If management budgets for wild lands cannot keep pace with mounting levels of threat, the species may rely increasingly on these southern African areas and may no longer be a flagship species of the once vast natural ecosystems across the rest of the continent.

"A man's game": cricket, war and masculinity, South Africa, 1899-1902.

Allen, Dean

2011-01-01

As practitioners of the imperial sport of the Victorian age, cricketers rallied whenever war descended upon England and its colonies. The South African War of 1899-1902 was no different. Adding to existing work on cricket's imperial development within South Africa, this study marks a significant contribution to research on the link between masculinity, war and sport during the Victorian era. A concept emerging from the English public schools of the mid- to late nineteenth century, the masculine ethos of sport and military honour had reached colonial South Africa by the outbreak of war in 1899. In its analysis of cricket and masculinity, this essay examines the events surrounding the war in South Africa and provides an example of the distinct relationship that existed between the military and the masculinity of sport and its organisation during this era.

An overview of regional and local characteristics of aerosols in South Africa using satellite, ground, and modeling data

We present a comprehensive overview of particulate air quality across the five major metropolitan areas of South Africa (Cape Town, Bloemfontein, Johannesburg and Tshwane (Gauteng Province), the Industrial Highveld Air Quality Priority Area (HVAPA), and Durban), based on a decadal (1 January 2000 to 31 December 2009) aerosol climatology from multiple satellite platforms and a detailed analysis of ground-based data from 19 sites throughout Gauteng. Data include Aerosol Optical Depth (AOD550, 555) from Aqua (550 nm), Terra (550 nm), and MISR (555 nm) platforms, Ängström Exponent (α550/865, 470/660) from Aqua (550/865 nm) and Terra (470/660 nm), Ultraviolet Aerosol Index (UVAI) from TOMS, and model results from the Goddard Ozone Chemistry Aerosol Radiation and Transport (GOCART) model. Results in Cape Town are distinct, owing to a typically clean, marine airmass origin and infrequent continental influence. At continentally-influenced sites, AOD550, AOD555, α550/865, α470/660 and UVAI reach maxima (0.12-0.20, 1.0-1.8, and 1.0-1.2, respectively) during late winter and early spring (August-October), coinciding with a period of enhanced dust generation and the maximum frequency of close-proximity and subtropical fires identified by MODIS Fire Information for Resource Management System (FIRMS). The adjacent metropolitan and industrial Gauteng and HVAPA areas have been identified as a megacity based on NO2 concentrations, but AOD is a factor of 3-6 lower than other megacities worldwide. GOCART results suggest that the contributions of organics and black carbon to AOD are significantly enhanced during biomass burning season (ASO), but that sulfate is the most significant contributor to AOD (~70-80%) through the rest of the year. Dust appears to be underestimated by GOCART emissions inventories at continentally-influenced metropolitan areas of South Africa. Ground monitoring sites were classified according to site type: (1) township and informal settlement sites with domestic burning influence, (2) urban and suburban residential sites with no domestic burning in the immediate vicinity, (3) industrial sites, and (4) one traffic site situated at a major freeway interchange. PM10 concentrations in township areas are 56% higher than in developed residential areas and 78% higher than in industrial areas as an annual average, with PM10 in townships 63 and 136% higher than developed residential and industrial areas, respectively, in winter (June, July, August). Monthly PM10 and PM2.5 concentrations reach annual maxima during winter at all sites except in industrial areas. At industrial sites, maxima in PM10 and PM2.5 tend to occur during summer (December-February), when photochemical generation of secondary aerosol is expected and when deep and unstable boundary layers allow high stack emissions (emitted above the boundary layer during winter) to reach the ground in close proximity to point sources. Diurnal profiles of PM10 and PM2.5 display maxima during morning (06:00-09:00 LT) and evening (17:00-22:00 LT) at nearly every site - especially during winter - and underscore the importance of domestic burning as a major source of primary particles. Multi-year averages indicate that evening maxima at some township sites average in excess of 400 μg m-3. These results from the urban/industrial Gauteng area quantitatively confirm previous studies suggesting that the lowest-income populations of South Africa experience the poorest air quality, and demonstrate that domestic burning results in frequent exposure to high concentrations of particulate pollution in the region comprising the cities of Johannesburg and Tshwane. While remotely-sensed data are frequently used as a proxy for ground air quality, we report poor correlations between PM concentrations and satellite parameters and suggest that this practice is not appropriate in metropolitan South Africa. Disagreement between satellite and ground data may be attributed to a number of factors: (1) vertical inhomogeneity and stratified pollution layers aloft during much of the year, (2) extremely shallow winter boundary layers, (3) discrepancy between satellite passover times and elevated diurnal PM concentrations, and (4) poor spatial resolution of satellites compared with highly localized PM sources. While remotely-sensed data provide a good picture of regional, seasonal properties of column aerosol, a complete understanding of South Africa's air quality at the ground will necessitate more extensive monitoring at the ground and intensive, multi-platform campaigns to understand the relationship between ground and satellite data.

High rates of tuberculosis (TB) and TB/HIV co-infection is often linked with mental health issues such as post-traumatic stress disorder (PTSD) symptoms, which is further associated with poor health outcomes. In a country such as South Africa where rates of these infectious diseases are high, it is concerning that there is limited/no data on prevalence rates of mental disorders such as PTSD and its associated factors. Therefore, the aim of this study was to establish the prevalence of PTSD symptoms and associated factors in TB, TB retreatment and/or TB-HIV co-infected primary public health-care patients in three districts in South Africa. Brief screening self-report tools were used to measure: PTSD symptoms, psychological distress (anxiety and depression) and alcohol misuse. Other relevant measures, such as adherence to medication, stressful life events and sexual risk-taking behaviours, were obtained through structured questions. A total of 4900 public primary care adult patients from clinics in high TB burden districts from three provinces in South Africa participated. All the patients screened positive for TB (either new or retreatment cases). The prevalence of PTSD symptoms was 29.6%. Patients who screened positive for PTSD symptoms and psychological distress were more likely to be on antidepressant medication. Factors that predicted PTSD symptoms were poverty, residing in an urban area, psychological distress, suicide attempt, alcohol and/or drug use before sex, unprotected sex, TB-HIV co-infected and the number of other chronic conditions. Health-care systems should be strengthened to improve delivery of mental health care, by focusing on existing programmes and activities, such as those which address the prevention and treatment of TB and HIV.

Malaria rapid diagnostic tests (RDTs) are relatively simple to perform and provide results quickly for making treatment decisions. However, the accuracy and application of RDT results depends on several factors such as quality of the RDT, storage, transport and end user performance. A cross sectional survey to explore factors that affect the performance and use of RDTs was conducted in the primary care facilities in South Africa. This study was conducted in three malaria risk sub-districts of the Limpopo Province, in South Africa. Twenty nurses were randomly selected from 17 primary health care facilities, three nurses from hospitals serving the study area and 10 other key informants, representing the managers of the malaria control programmes, routine and research laboratories, were interviewed, using semi-structured questionnaires. There was a high degree of efficiency in ordering and distribution of RDTs, however only 13/20 (65%) of the health facilities had appropriate air-conditioning and monitoring of room temperatures. Sixty percent (12/20) of the nurses did not receive any external training on conducting and interpreting RDT. Fifty percent of nurses (10/20) reported RDT stock-outs. Only 3/20 nurses mentioned that they periodically checked quality of RDT. Fifteen percent of nurses reported giving antimalarial drugs even if the RDT was negative. Storage, quality assurance, end user training and use of RDT results for clinical decision making in primary care facilities in South Africa need to be improved. Further studies of the factors influencing the quality control of RDTs, their performance of RDTs and the ways to improve their use of RDTs are needed.

Bullying victimisation has been prospectively linked with mental health problems among children and adolescents in longitudinal studies in the developed world. However, research from the developing world, where adolescents face multiple risks to social and emotional development, has been limited by cross-sectional designs. This is the first longitudinal study of the psychological impacts of bullying victimisation in South Africa. The primary aim was to examine prospective relationships between bullying victimisation and internalising and externalising symptoms in South African youth. Secondary aims were to examine gender and age-related differences in experiences of bullying victimisation. Children and adolescents (10-17 years, 57 % female, n = 3,515) from high HIV-prevalent (>30 %) communities in South Africa were interviewed and followed-up 1 year later (97 % retention). Census enumeration areas were randomly selected from urban and rural sites in two provinces and door-to-door sampling included all households with a resident child/adolescent. Exposure to multiple experiences of bullying victimisation at baseline predicted internalising symptoms and conduct problems 1 year later. Additionally, baseline mental health scores predicted later bullying victimisation, demonstrating bi-directionality of relationships between bullying victimisation and mental health outcomes in this sample. Expected gender differences in physical, verbal, and relational bullying victimisation were evident and predicted declines in bullying victimisation over time were observed. In the developed world, school-based anti-bullying programmes have been shown to be effective in reducing bullying and victimisation. Anti-bullying programmes should be implemented and rigorously evaluated in South Africa, as this may promote improved mental health among South African children and adolescents.

The United Nations (UN) Convention on the Rights of Persons with Disabilities (CRPD) is a milestone in the recognition of the human rights of persons with disabilities, including the right to health and rehabilitation. South Africa has signed and ratified the CRPD but still has a long way to go in reforming policies and systems in order to be in compliance with the convention. This paper seeks to fill a gap in the literature by exploring what the barriers to the implementation of the health and rehabilitation articles of the CRPD are, as identified by representatives of the disability community. This investigation used a qualitative, exploratory methodology. 10 semi-structured interviews of a purposive sample of representatives of disabled persons organizations (DPOs), non-governmental organizations (NGOs), and service providers in South Africa were conducted. Participants were drawn from urban, peri-urban, and rural settings in order to reflect diverse perspectives within South Africa. Data was analysed using a multi-stage coding process to establish the main categories and relationships between them. Six main categories of barriers to the implementation of the health and rehabilitation articles of the CRPD were identified. Attitude barriers including stigma and negative assumptions about persons with disabilities were seen as an underlying cause and influence on all of the other categories; which included political, financial, health systems, physical, and communication barriers. The findings of this study have important implications for strategies and actions to implement the CRPD. Given the centrality of attitudinal barriers, greater sensitization around the area of disability is needed. Furthermore, disability should be better integrated and mainstreamed into more general initiatives to develop the health system and improve the lives of persons living in poverty in South Africa. © 2017 The Author(s); Published by Kerman University of Medical Sciences.

Physical and emotional abuse of children is a large scale problem in South Africa, with severe negative outcomes for survivors. Although chronic household illness has shown to be a predictor for physical and emotional abuse, no research has thus far investigated the different pathways from household chronic illness to child abuse victimisation in South Africa. Confidential self-report questionnaires using internationally utilised measures were completed by children aged 10-17 (n = 3515, 56.7% female) using door-to-door sampling in randomly selected areas in rural and urban locations of South Africa. Follow-up surveys were conducted a year later (96.7% retention rate). Using multiple mediation analyses, this study investigated direct and indirect effects of chronic household illness (AIDS or other illness) on frequent (monthly) physical and emotional abuse victimisation with poverty and extent of the ill person's disability as hypothesised mediators. For children in AIDS-ill families, a positive direct effect on physical abuse was obtained. In addition, positive indirect effects through poverty and disability were established. For boys, a positive direct and indirect effect of AIDS-illness on emotional abuse through poverty were detected. For girls, a positive indirect effect through poverty was observed. For children in households with other chronic illness, a negative indirect effect on physical abuse was obtained. In addition, a negative indirect effect through poverty and positive indirect effect through disability was established. For boys, positive and negative indirect effects through poverty and disability were found respectively. For girls, a negative indirect effect through poverty was observed. These results indicate that children in families affected by AIDS-illness are at higher risk of child abuse victimisation, and this risk is mediated by higher levels of poverty and disability. Children affected by other chronic illness are at lower risk for abuse victimisation unless they are subject to higher levels of household disability. Interventions aiming to reduce poverty and increase family support may help prevent child abuse in families experiencing illness in South Africa.

Personal factors, especially attitude, have been implicated in the utilization of health care services, and in access to medical treatment. There is little information on the attitudes of the general public in South Africa towards medications and whether attitudes differ across population groups or among the different users of the health care system. This study aimed to determine the general attitude of a local population to medications, self-care orientation and health professional contact, and whether differences existed between age groups, gender and race groups. METHODS We carried out a randomized, cross-sectional quantitative study via telephonic questionnaire survey (adapted from a previous study) of a sample of 1132 telephone numbers. The setting was the Durban Metropolitan Area, KwaZulu-Natal, South Africa. KEY FINDINGS A total of 500 (44.2%) people responded. The majority had a positive attitude towards medication. An increase in age resulted in increased medication use. Females were more likely than males to use medication and seek professional health care (P = 0.0406). Most of the respondents (86.0%) were self-care-orientated and displayed moderate medication knowledge (46.2%). Some 295 (59.0%) of the 500 respondents had visited a pharmacy within the last 6 months. Conclusions Health care professionals can adopt an informed approach to address the needs of the population with regard to medication, by targeting groups more likely to use medication (females and the older age group). In addition, gaps in medication knowledge were identified which could be used for health-promotion interventions by health care workers.

Accessibility, affordability and use of health services in an urban area in South Africa.

Inequalities in healthcare between population groups of South Africa existed during the apartheid era and continue to exist both between and within many population groups. Accessibility and affordability of healthcare is a human right. The aim of the study was to explore and describe accessibility, affordability and the use of health services by the mixed race (coloured) population in the Western Cape, South Africa. A cross-sectional descriptive, non-experimental study with a quantitative approach was applied. A purposive convenient sample of 353 participants (0.6%) was drawn from a population of 63 004 economically-active people who lived in the residential areas as defined for the purpose of the study. All social classes were represented. The hypothesis set was that there is a positive relationship between accessibility, affordability and the use of health services. A pilot study was conducted which also supported the reliability and validity of the study. Ethics approval was obtained from the University of Stellenbosch and informed consent from respondents. A questionnaire was used to collect the data. The hypothesis was accepted. The statistical association between affordability (p = < 0.01), accessibility (p = < 0.01) and the use of health services was found to be significant using the Chi-square (χ²) test. The study has shown how affordability and accessibility may influence the use of healthcare services. Accessibility is not only the distance an individual must travel to reach the health service point but more so the utilisation of these services. Continuous Quality Management should be a priority in healthcare services, which should be user-friendly.

Little is known about gender differences in aetiology and management of acute burns in resource-constrained settings in South Africa. This cross-sectional study is based on burn case reports (n=1915) from eight emergency centres in Western Cape, South Africa (June 2012-May 2013). Male/female rate ratios by age group and age-specific incidence rates were compiled for urban and rural areas along with gender differences in proportions between children and adults for injury aetiology, burn severity, length of stay and patient disposition. Children 0-4 years in urban areas had the highest burn incidence but only among adults did male rates surpass females, with fire burns more common among men 20-39 years and hot liquid burns among men 55+ years. Men had a higher proportion of burns during weekends, from interpersonal violence and suspected use of alcohol/other substances, with more pronounced differences for hot liquid burns. Despite similar Abbreviated Injury Scale (AIS) scores, men were more often transferred to higher levels of care and women more often treated and discharged. Burns were far more common among children although gender differences arose only among adults. Men sustained more injuries of somewhat different aetiology and were referred to higher levels of care more often for comparable wound severity. The results suggest different disposition between men and women despite similar AIS scores. However, further studies with more comprehensive information on severity level and other care- and patient-related factors are needed to explore these results further. Copyright © 2016 The Author(s).

2016-12-01

While the HIV epidemic in South Africa had a later onset than epidemics in other southern African countries, prevalence grew rapidly during the 1990's when the country was going through socio-political changes with the end of Apartheid. South Africa currently has the largest number of people living with HIV in the world and the epidemic is dominated by a unique subtype, HIV-1 subtype C. This large epidemic is also characterized by high level of genetic diversity. We hypothesize that this diversity is due to multiple introductions of the virus during the period of change. In this paper, we apply novel phylogeographic methods to estimate the number of viral imports and exports from the start of the epidemic to the present. We assembled 11,289 unique subtype C pol sequences from southern Africa. These represent one of the largest sequence datasets ever analyzed in the region. Sequences were stratified based on country of sampling and levels of genetic diversity were estimated for each country. Sequences were aligned and a maximum-likelihood evolutionary tree was inferred. Least-Squares Dating was then used to obtain a dated phylogeny from which we estimated the number of introductions into and exports out of South Africa using parsimony-based ancestral location reconstructions. Our results identified 189 viral introductions into South Africa with the largest number of introductions attributed to Zambia (n=109), Botswana (n=32), Malawi (n=26) and Zimbabwe (n=13). South Africa also exported many viral lineages to its neighbours. The bulk viral imports and exports appear to have occurred between 1985 and 2000, coincident with the period of socio-political transition. The high level of subtype C genetic diversity in South Africa is related to multiple introductions of the virus to the country. While the number of viral imports and exports we identified was highly sensitive to the number of samples included from each country, they mostly clustered around the period of rapid political and socio-economic change in South Africa.

South Africa is a country in the midst of transformation. Political changes within the country, and the ensuing empowerment of the black majority, have created a situation where dramatic improvements are needed in the country`s infrastructure in order to enable it to meet the needs of all its people over the coming decades. Largely as a result of the international embargo placed on South Africa during the apartheid era, the South African government became heavily involved in the country`s energy sector. This involvement included development of a synfuels program, price controls in the oil sector, monopolies in both upstream andmore » downstream oil sectors, and a strong centralized electric power company. In 1994, South Africa became the eleventh member of the Southern Africa Development Community (SADC), an organization which was established in 1980 to synchronize development plans for its member countries. SADC is presently working to formulate a regional energy development plan, and coordinate technical information exchanges and joint research needs. Each of the SADC nations have also begun to develop their regional electricity grids and other parts of their energy infrastructure to plan for the growing needs of the 500 million people who live in sub-Saharan Africa. South Africa, in particular, must make significant changes in each of its energy sectors in the near future, to keep up with its growing energy requirements. These changes translate to opportunity for the US Power Industry.« less

There is limited evidence on the acceptability, feasibility and cost-effectiveness of task-sharing interventions to narrow the treatment gap for mental disorders in sub-Saharan Africa. The purpose of this article is to describe the rationale, aims and methods of the Africa Focus on Intervention Research for Mental health (AFFIRM) collaborative research hub. AFFIRM is investigating strategies for narrowing the treatment gap for mental disorders in sub-Saharan Africa in four areas. First, it is assessing the feasibility, acceptability and cost-effectiveness of task-sharing interventions by conducting randomised controlled trials in Ethiopia and South Africa. The AFFIRM Task-sharing for the Care of Severe mental disorders (TaSCS) trial in Ethiopia aims to determine the acceptability, affordability, effectiveness and sustainability of mental health care for people with severe mental disorder delivered by trained and supervised non-specialist, primary health care workers compared with an existing psychiatric nurse-led service. The AFFIRM trial in South Africa aims to determine the cost-effectiveness of a task-sharing counselling intervention for maternal depression, delivered by non-specialist community health workers, and to examine factors influencing the implementation of the intervention and future scale up. Second, AFFIRM is building individual and institutional capacity for intervention research in sub-Saharan Africa by providing fellowship and mentorship programmes for candidates in Ethiopia, Ghana, Malawi, Uganda and Zimbabwe. Each year five Fellowships are awarded (one to each country) to attend the MPhil in Public Mental Health, a joint postgraduate programme at the University of Cape Town and Stellenbosch University. AFFIRM also offers short courses in intervention research, and supports PhD students attached to the trials in Ethiopia and South Africa. Third, AFFIRM is collaborating with other regional National Institute of Mental Health funded hubs in Latin America, sub-Saharan Africa and south Asia, by designing and executing shared research projects related to task-sharing and narrowing the treatment gap. Finally, it is establishing a network of collaboration between researchers, non-governmental organisations and government agencies that facilitates the translation of research knowledge into policy and practice. This article describes the developmental process of this multi-site approach, and provides a narrative of challenges and opportunities that have arisen during the early phases. Crucial to the long-term sustainability of this work is the nurturing and sustaining of partnerships between African mental health researchers, policy makers, practitioners and international collaborators.

Healthcare service problems reported in a national survey of South Africans.

To identify common types of health service problems reported by South African adults during their most recent visit to a healthcare provider. Secondary analysis of South Africa's cross-sectional General Household Survey (GHS). Nationally representative weighted sample of households in South Africa. 23,562 household representatives interviewed during the 2010 GHS. Problems experienced during the most recent visit to the usual healthcare provider. In total, 43.8% of participants reported experiencing at least one problem during their last visit; 19.1% reported multiple problems. The most common problems experienced were a long waiting time (34.8% of household representatives), needed drugs not being available (14.1%) and staff who were rude or uncaring or turned patients away (10.1%). Of the 73.6% of participants using public providers, 54.9% reported at least one problem; of the 26.4% of participants using private providers, only 18.0% reported a problem, usually cost. Similar differences in reported problems at public and private providers were reported for all racial/ethnic groups and income groups. Black Africans reported more problems than other population groups due in large part to being significantly more likely to use public providers. Addressing commonly reported problem areas-in particular, long waiting times, unavailable medications and staff who are perceived as being unfriendly-might help prevent delayed care seeking, increase the acceptability of healthcare services and reduce remaining health disparities in South Africa. © The Author 2014.

2015-12-01

To evaluate whether the updated South African national contraception policy and guidelines adequately address the needs of adolescents. We used the World Health Organization (WHO) guidance and recommendations on ensuring human rights in the provision of contraceptive information and services as an analytic framework. We assessed the South African policy in relation to each WHO summary recommendation. Specifically, we determined where normative guidance pertaining to adolescents is present and whether it is adequate, normative guidance pertaining to all populations but not specifically adolescents is present, or normative guidance for that recommendation is missing from the policy. We developed an analytic table to discuss with coauthors and draw conclusions. We found specific guidance for adolescents relating to 6/9 WHO summary recommendations and 11/24 subrecommendations. Adolescents are highlighted throughout the policy as being at risk for discrimination or coercion, and laws protecting the rights of adolescents are cited. Confidentiality of services for young people is emphasized, and youth-friendly services are described as a key element of service delivery. Areas to strengthen include the need for normative guidance ensuring both availability of contraceptive information and services for young people and adolescent participation in development of community programs and services. South Africa's contraception policy and guidelines are comprehensive and forward looking. Nevertheless, there are gaps that may leave adolescents vulnerable to discrimination and coercion and create barriers to accessing contraceptive services. These findings provide insight for the revision and development of adolescent health policies in South Africa and other settings. Copyright © 2015. Published by Elsevier Inc.

Adherence barriers and facilitators for cervical screening amongst currently disadvantaged women in the greater Cape Town region of South Africa

De Abreu, Chantelle; Horsfall, Hannah

2013-01-01

Abstract Background In South Africa cervical cancer is the second most commonly occurring cancer amongst women, and black African women have the highest risk of developing this disease. Unfortunately, the majority of South African women do not adhere to recommended regular cervical screening. Objectives The purpose of this research was to explore the perceptions, experiences and knowledge regarding cervical screening of disadvantaged women in two informal settlements in South African urban areas. Method The Health Belief Model (HBM) provided a theoretical framework for this study. Four focus groups (n = 21) were conducted, using questions derived from the HBM, and thematic analysis was used to analyse the data. The ages of the women who participated ranged from 21 to 53 years. Results The analysis revealed lack of knowledge about screening as a key structural barrier to treatment. Other structural barriers were: time, age at which free screening is available, and health education. The psychosocial barriers that were identified included: fear of the screening procedure and of the stigmatisation in attending screening. The presence of physical symptoms, the perception that screening provides symptom relief, HIV status, and the desire to know one's physical health status were identified as facilitators of cervical screening adherence. Conclusion This knowledge has the potential to inform healthcare policy and services in South Africa. As globalisation persists and individuals continue to immigrate or seek refugee status in foreign countries, increased understanding and knowledge is required for successful acculturation and integration. Developed countries may therefore also benefit from research findings in developing countries.

Asbestos-Related Disease in South Africa

South Africa was the third largest exporter of asbestos in the world for more than a century. As a consequence of particularly exploitative social conditions, former workers and residents of mining regions suffered—and continue to suffer—from a serious yet still largely undocumented burden of asbestos-related disease. This epidemic has been invisible both internationally and inside South Africa. We examined the work environment, labor policies, and occupational-health framework of the asbestos industry in South Africa during the 20th century. In a changing local context where the majority of workers were increasingly disenfranchised, unorganized, excluded from skilled work, and predominantly rural, mining operations of the asbestos industry not only exposed workers to high levels of asbestos but also contaminated the environment extensively.

Given the dual epidemics of HIV and tuberculosis in sub-Saharan Africa and evidence suggesting a disproportionate burden of these diseases among detainees in the region, we aimed to investigate the epidemiology of HIV and tuberculosis in prison populations, describe services available and challenges to service delivery, and identify priority areas for programmatically relevant research in sub-Saharan African prisons. To this end, we reviewed literature on HIV and tuberculosis in sub-Saharan African prisons published between 2011 and 2015, and identified data from only 24 of the 49 countries in the region. Where data were available, they were frequently of poor quality and rarely nationally representative. Prevalence of HIV infection ranged from 2·3% to 34·9%, and of tuberculosis from 0·4 to 16·3%; detainees nearly always had a higher prevalence of both diseases than did the non-incarcerated population in the same country. We identified barriers to prevention, treatment, and care services in published work and through five case studies of prison health policies and services in Zambia, South Africa, Malawi, Nigeria, and Benin. These barriers included severe financial and human-resource limitations and fragmented referral systems that prevent continuity of care when detainees cycle into and out of prison, or move between prisons. These challenges are set against the backdrop of weak health and criminal-justice systems, high rates of pre-trial detention, and overcrowding. A few examples of promising practices exist, including routine voluntary testing for HIV and screening for tuberculosis upon entry to South African and the largest Zambian prisons, reforms to pre-trial detention in South Africa, integration of mental health services into a health package in selected Malawian prisons, and task sharing to include detainees in care provision through peer-educator programmes in Rwanda, Zimbabwe, Zambia, and South Africa. However, substantial additional investments are required throughout sub-Saharan Africa to develop country-level policy guidance, build human-resource capacity, and strengthen prison health systems to ensure universal access to HIV and tuberculsosis prevention, treatment, and care of a standard that meets international goals and human rights obligations.

Quantitative Risk Assessment for African Horse Sickness in Live Horses Exported from South Africa

PubMed Central

Sergeant, Evan S.

2016-01-01

African horse sickness (AHS) is a severe, often fatal, arbovirus infection of horses, transmitted by Culicoides spp. midges. AHS occurs in most of sub-Saharan Africa and is a significant impediment to export of live horses from infected countries, such as South Africa. A stochastic risk model was developed to estimate the probability of exporting an undetected AHS-infected horse through a vector protected pre-export quarantine facility, in accordance with OIE recommendations for trade from an infected country. The model also allows for additional risk management measures, including multiple PCR tests prior to and during pre-export quarantine and optionally during post-arrival quarantine, as well as for comparison of risk associated with exports from a demonstrated low-risk area for AHS and an area where AHS is endemic. If 1 million horses were exported from the low-risk area with no post-arrival quarantine we estimate the median number of infected horses to be 5.4 (95% prediction interval 0.5 to 41). This equates to an annual probability of 0.0016 (95% PI: 0.00015 to 0.012) assuming 300 horses exported per year. An additional PCR test while in vector-protected post-arrival quarantine reduced these probabilities by approximately 12-fold. Probabilities for horses exported from an area where AHS is endemic were approximately 15 to 17 times higher than for horses exported from the low-risk area under comparable scenarios. The probability of undetected AHS infection in horses exported from an infected country can be minimised by appropriate risk management measures. The final choice of risk management measures depends on the level of risk acceptable to the importing country. PMID:26986002

African horse sickness (AHS) is a severe, often fatal, arbovirus infection of horses, transmitted by Culicoides spp. midges. AHS occurs in most of sub-Saharan Africa and is a significant impediment to export of live horses from infected countries, such as South Africa. A stochastic risk model was developed to estimate the probability of exporting an undetected AHS-infected horse through a vector protected pre-export quarantine facility, in accordance with OIE recommendations for trade from an infected country. The model also allows for additional risk management measures, including multiple PCR tests prior to and during pre-export quarantine and optionally during post-arrival quarantine, as well as for comparison of risk associated with exports from a demonstrated low-risk area for AHS and an area where AHS is endemic. If 1 million horses were exported from the low-risk area with no post-arrival quarantine we estimate the median number of infected horses to be 5.4 (95% prediction interval 0.5 to 41). This equates to an annual probability of 0.0016 (95% PI: 0.00015 to 0.012) assuming 300 horses exported per year. An additional PCR test while in vector-protected post-arrival quarantine reduced these probabilities by approximately 12-fold. Probabilities for horses exported from an area where AHS is endemic were approximately 15 to 17 times higher than for horses exported from the low-risk area under comparable scenarios. The probability of undetected AHS infection in horses exported from an infected country can be minimised by appropriate risk management measures. The final choice of risk management measures depends on the level of risk acceptable to the importing country.

South Africa is host to the largest single known platinum group metal supply in the world. The Bushveld Igneous Complex, spanning 300x400 kilometers, hosts hundreds of years' worth of platinum, chromite, vanadium, and other ore. Its wealth of these metals is tied directly to the large layered igneous intrusion that formed roughly 2061 million years ago. The extraction of platinum is vital to the industrial world - as these metals are widely used in the automotive industry, dental restorations, computer technology, in addition to many other applications. In collaboration with the Africa Array geophysics field school and the Penn State Summer Research Opportunities Program (SROP), we surveyed the Modikwa mine located along the border of the provinces of Mpumalanga and Limpopo in South Africa. The following techniques were applied to survey the area of interest: seismic refraction and reflection, gravity, magnetics, electrical resistivity, and electromagnetics. The data collected were used to determine the depth to bedrock and to identify potential mining hazards from dykes and faults in the bedrock. Several areas were studied and with the combination of the above-mentioned methods several possible hazards were identified. One broad, major dyke that was located in a prior aeromagnetic survey and several previously undetected, parallel, minor dykes were identified in the region. The overburden thickness was determined to be ̴4-5 meters in some regions, and as thin as several centimeters in others. This section of rock and soil lies above an area where platinum will likely be mined in the future. The removal of overburden can be accomplished by using power shovels or scrapers; while remaining material can be contained with the use of galvanized steel culverts. Additionally, a number of joints were located that may have allowed water to accumulate underground. The models created from the data permit us to estimate which hazards could be present in different parts of the land surveyed. These results are important information that will help determine how deep to mine while also avoiding hazards that could result in serious injuries to personnel or cause costly damages to equipment.

The enigma of yellow fever in East Africa.

Despite a safe and effective vaccine, there are approximately 200,000 cases, including 30,000 deaths, due to yellow fever virus (YFV) each year, of which 90% are in Africa. The natural history of YFV has been well described, especially in West Africa, but in East Africa yellow fever (YF) remains characterised by unpredictable focal periodicity and a precarious potential for large epidemics. Recent outbreaks of YF in Kenya (1992-1993) and Sudan (2003 and 2005) are important because each of these outbreaks have involved the re-emergence of a YFV genotype (East Africa) that remained undetected for nearly 40 years and was previously unconfirmed in a clinically apparent outbreak. In addition, unlike West Africa and South America, YF has yet to emerge in urban areas of East Africa and be vectored by Aedes (Stegomyia) aegypti. This is a significant public health concern in a region where the majority of the population remains unvaccinated. This review describes historical findings, highlights a number of disease indicators, and provides clarification regarding the natural history, recent emergence and future risk of YF in East Africa.

Review: Groundwater management and groundwater/surface-water interaction in the context of South African water policy

Groundwater/surface-water interaction is receiving increasing focus in Africa due to its importance to ecologic systems and sustainability. In South Africa's 1998 National Water Act (NWA), water-use licenses, including groundwater, are granted only after defining the Reserve, the amount of water needed to supply basic human needs and preserve some ecological integrity. Accurate quantification of groundwater contributions to ecosystems for successful implementation of the NWA proves challenging; many of South Africa's aquifers are in heterogeneous and anisotropic fractured-rock settings. This paper reviews the current conceptualizations and investigative approaches regarding groundwater/surface-water interactions in the context of South African policies. Some selected pitfall experiences are emphasized. The most common approach in South Africa is estimation of average annual fluxes at the scale of fourth-order catchments (˜500 km2) with baseflow separation techniques and then subtracting the groundwater discharge rate from the recharge rate. This approach might be a good start, but it ignores spatial and temporal variability, potentially missing local impacts associated with production-well placement. As South Africa's NWA has already been emulated in many countries including Zambia, Zimbabwe and Kenya, the successes and failures of the South African experience dealing with the groundwater/surface-water interaction will be analyzed to guide future policy directions.
