  1. Population, agriculture and food.

    1982-06-01

    Data published by the UN Statistical Office and the Food and Agriculture Organization (FAO) indicates that food production in the world grew at an average annual rate of 2.5% during the period 1961-65 to 1980 whereas during the same period the population growth rate was 1.9% per annum, declining further to 1.8 toward the late 1970s. Yet, the food production growth trend has been most uneven. The situation in Asia has been more or less similar to the global trend. During 1962-72 the rate of population growth increased to 2.5% whereas the annual increase in food production dropped from 3.1 to 2.7%. Throughout the remainder of the 1970s, food production barely managed to keep pace with population growth. Closer analysis reveals that in about the mid 1960s food production fell behind population growth, and near famine situations developed in certain drought affected areas of India, Indonesia, and Pakistan. These countries had to import food to meet the situation at the cost of their economic development programs. According to the UN projections, the region's population will continue to grow at an average of 1.7% per annum up to 2000 despite the declining fertility trend. To cope with the population growth rate and the changing pattern of food consumption even at the present level of nutrition, Asian nations will have to increase food production annually at a 3% compound rate. An increase in food production basically means increasing the inputs of different factors of production such as land and water, labor, materials, and various types of capital and technological know how. The application of these factors in the developing countries largely depends on the infrastructure and services provided by the governments. 2 approaches are generally made in an effort to achieve the objective of increasing food production: horizontal expansion approach, used to bring new land under cultivation so as to produce more food; and the vertical expansion approach, used to increase the

    As global populations continue to increase, agricultural productivity will be challenged to keep pace without overtaxing important environmental resources. A dynamic and integrated approach will be required to solve global food insecurity and position agriculture on a trajectory toward sustainability. Genetically modified (GM) crops enhanced through modern biotechnology represent an important set of tools that can promote sustainable agriculture and improve food security. Several emerging biotechnology approaches were discussed in a recent symposium organized at the 13th IUPAC International Congress of Pesticide Chemistry meeting in San Francisco, CA, USA. This paper summarizes the innovative research and several of the new and emerging technologies within the field of agricultural biotechnology that were presented during the symposium. This discussion highlights how agricultural biotechnology fits within the context of sustainable agriculture and improved food security and can be used in support of further development and adoption of beneficial GM crops.

    Precision agriculture comprises a set of technologies that combines sensors, information systems, enhanced machinery, and informed management to optimize production by accounting for variability and uncertainties within agricultural systems. Adapting production inputs site-specifically within a field and individually for each animal allows better use of resources to maintain the quality of the environment while improving the sustainability of the food supply. Precision agriculture provides a means to monitor the food production chain and manage both the quantity and quality of agricultural produce.

    Climate-smart agriculture (CSA) is an approach for transforming and reorienting agricultural systems to support food security under the new realities of climate change. Widespread changes in rainfall and temperature patterns threaten agricultural production and increase the vulnerability of people dependent on agriculture for their livelihoods, which includes most of the world's poor. Climate change disrupts food markets, posing population-wide risks to food supply. Threats can be reduced by increasing the adaptive capacity of farmers as well as increasing resilience and resource use efficiency in agricultural production systems. CSA promotes coordinated actions by farmers, researchers, private sector, civil society and policymakers towards climate-resilient pathways through four main action areas: (1) building evidence; (2) increasing local institutional effectiveness; (3) fostering coherence between climate and agricultural policies; and (4) linking climate and agricultural financing. CSA differs from 'business-as-usual' approaches by emphasizing the capacity to implement flexible, context-specific solutions, supported by innovative policy and financing actions.

  9. The roles and values of wild foods in agricultural systems

    2010-01-01

    Almost every ecosystem has been amended so that plants and animals can be used as food, fibre, fodder, medicines, traps and weapons. Historically, wild plants and animals were sole dietary components for hunter–gatherer and forager cultures. Today, they remain key to many agricultural communities. The mean use of wild foods by agricultural and forager communities in 22 countries of Asia and Africa (36 studies) is 90–100 species per location. Aggregate country estimates can reach 300–800 species (e.g. India, Ethiopia, Kenya). The mean use of wild species is 120 per community for indigenous communities in both industrialized and developing countries. Many of these wild foods are actively managed, suggesting there is a false dichotomy around ideas of the agricultural and the wild: hunter–gatherers and foragers farm and manage their environments, and cultivators use many wild plants and animals. Yet, provision of and access to these sources of food may be declining as natural habitats come under increasing pressure from development, conservation-exclusions and agricultural expansion. Despite their value, wild foods are excluded from official statistics on economic values of natural resources. It is clear that wild plants and animals continue to form a significant proportion of the global food basket, and while a variety of social and ecological drivers are acting to reduce wild food use, their importance may be set to grow as pressures on agricultural productivity increase.

  10. Oligosaccharides in Food and Agriculture

    Collins, Michelle E.; Rastall, Robert A.

    Oligosaccharides are an integral part of the daily diet for humans and animals. They are primarily used for their nutritional properties, however they are currently receiving much attention due to their physiological effect on the microflora of the gastrointestinal tract. Galacto-oligosaccharides and the fructan-type oligosaccharides, namely FOS and inulin are well established as beneficial to the host and are classified as prebiotic based on data from clinical studies. These compounds dominate this sector of the market, although there are oligosaccharides emerging which have produced very interesting in vitro results in terms of prebiotic status and human trials are required to strengthen the claim. Such compounds include pectic oligosaccharides, gluco-oligosaccharides, gentio-oligosaccharides, kojio-oligosaccharides, and alternan oligosaccharides. The raw materials for production of these prebiotic compounds are derived from natural sources such as plants but also from by products of the food processing industry. In addition to being prebiotic these compounds can be incorporated into foodstuffs due to the physiochemical properties they possess.

    In Hungary, plougland decreased to 52% of its area by the time of political restructuring (1989) in comparison with the 1950s. Forested areas increased significantly (18%) and lands withdrawn from agricultural production doubled (11%). For today, these proportions further changed. Ploughlands reduced to 46% and forested areas further increased (21%) in 2013. The most significat changes were observed in the proportion of lands withdrawn from agricultural production which increased to 21%. Temperature in Hungary increased by 1°C during the last century and predictions show a further 2.6 °C increase by 2050. The yearly amount of precipitation significantly decreased from 640 mm to 560 mm with a more uneven temporal distribution. The following aspects can be considered in the correlation between climate change and agriculture: a) impact of agriculture on climate, b) future impact of climate change on agriculture and food supply, c) impact of climate change on food security. The reason for the significant change of climate is the accumulation of greenhouse gases (GHG) which results from anthropological activities. Between 2008 and 2012, Hungary had to reduce its GHG emission by 6% compared to the base period between 1985-1987. At the end of 2011, Hungarian GHG emission was 43.1% lower than that of the base period. The total gross emission was 66.2 million CO2 equivalent, while the net emission which also includes land use, land use change and forestry was 62.8 million tons. The emission of agriculture was 8.8 million tons (OMSZ, 2013). The greatest opportunity to reduce agricultural GHG emission is dinitrogen oxides which can be significantly mitigated by the smaller extent and more efficient use of nitrogen-based fertilisers (precision farming) and by using biomanures produced from utilised waste materials. Plant and animal species which better adapt to extreme weather circumstances should be bred and maintained, thereby making an investment in food security. Climate

    1997-04-01

    The 1992 International Conference on Nutrition, new legislation in developing countries, and international trade agreements have renewed interest in food-composition data. Because of the costs involved in gathering such information and the need for it to be uniform, collaborative efforts are required. The production of new food-composition data must be viewed with respect to value gained for money spent, the need for more precise information, and the opportunity to use new analytic methods while not depending too heavily on high-technology systems. The Food and Agriculture Organization and the United Nations University have agreed to collaborate in stimulating the development of new food-composition programs. Their efforts will be directed toward promoting national, regional, and international activities in the food-composition field and will include strengthening existing laboratory facilities and programs, publishing technical manuals and documents, assisting countries to disseminate data, training workers, and sponsoring regional workshops. The Food and Agriculture Organization is well positioned to fulfill this coordinating role because of its past work in food composition, international mandates regarding its activities, its established communication system with national governments, and its ability to provide open forums for discussion of food-composition issues.

    Within 30 years the world will be supplying food for an additional 2.5 billion people, most of whom will live in developing countries. Developing countries in meeting future challenges will need to implement sound and stable macroeconomic and sector policies. The World Bank is providing analysis, policy dialogue, and financial support in specific countries for opening up agricultural markets globally. Developing countries need to enhance food supplies by encouraging rapid technological change, increasing the efficiency of irrigation, and improving natural resource management. Agricultural and income growth in developing countries is dependent upon transfer of the breakthroughs in agricultural technology to the millions of small farms in the developing world. People currently use about 70% of available fresh water for irrigation, and competition for water resources with urban and industrial users has increased. Agriculture and other sectors must increase the efficiency of water use. Natural resource planning and comprehensive water and natural resource management that rely on a community-based approach have proven successful. Developing countries need to improve access to food by strengthening markets and agribusinesses, providing education and health services to both boys and girls, investing in infrastructure, and fostering broad participation. The major challenge ahead is to ensure food security for the hundreds of millions of families living in poverty. This large and complex task involves increasing agricultural output worldwide, reducing poverty, and improving health and nutrition. Progress has been made in the past 25 years in improving living conditions, but not everyone has benefitted. Almost 75% of the poor live in rural areas without access to land, and 25% are urban poor without jobs. Most of the poor live in Asia and sub-Saharan Africa. The World Bank mandate is to reduce poverty and hunger through revitalized rural development.

    Liposomes, spherical bilayer vesicles from dispersion of polar lipids in aqueous solvents, have been widely studied for their ability to act as drug delivery vehicles by shielding reactive or sensitive compounds prior to release. Liposome entrapment has been shown to stabilize encapsulated, bioactive materials against a range of environmental and chemical changes, including enzymatic and chemical modification, as well as buffering against extreme pH, temperature, and ionic strength changes. Liposomes have been especially useful to researchers in studies of various physiological processes as models of biological membranes in both eukaryotes and prokaryotes. Industrial applications include encapsulation of pharmaceuticals and therapeutics, cosmetics, anti-cancer and gene therapy drugs. In the food industry, liposomes have been used to deliver food flavors and nutrients and more recently have been investigated for their ability to incorporate food antimicrobials that could aid in the protection of food products against growth of spoilage and pathogenic microorganisms. In this review we briefly introduce key physicochemical properties of liposomes and review competing methods for liposome production. A survey of non-agricultural and food applications of liposomes are given. Finally, a detailed up-to-date summary of the emerging usage of liposomes in the food industry as delivery vehicles of nutrients, nutraceuticals, food additives, and food antimicrobials is provided.

    Hunger has been a concern for generations and has continued to plague hundreds of millions of people around the world. Although many efforts have been devoted to reduce hunger, challenges such as growing competitions for natural resources, emerging climate changes and natural disasters, poverty, illiteracy, and diseases are posing threats to food security and intensifying the hunger crisis. Concerted efforts of scientists to improve agricultural and food productivity, technology, nutrition, and education are imperative to facilitate appropriate strategies for defeating hunger and malnutrition. This paper provides some aspects of world hunger issues and summarizes the efforts and measures aimed to alleviate food problems from the food and nutritional sciences perspectives. The prospects and constraints of some implemented strategies for alleviating hunger and achieving sustainable food security are also discussed. This comprehensive information source could provide insights into the development of a complementary framework for dealing with the global hunger issue. PMID:24188265

    Negative food challenges for follow-up in patients previously diagnosed with food allergy should logically be followed by a normal diet. However, all patients do not reintroduce the food. The aims of the study were to define the proportion of negative food challenge not followed by a normal diet, and to identify possible reasons for not reintroducing the food. Patients with a negative food challenge were sent a questionnaire by mail. Items in the questionnaire included the symptoms at diagnosis, the duration of the diet, the fear of an accidental reaction during the avoidance diet and how it influenced the social life. Patients were also asked if the food was reintroduced after the negative food challenge, and if not, for which reasons. In 25.4% of the questionnaires (18/71) respondents reported that the food was not reintroduced. Patients with a previous diagnosis of peanut allergy tended to reintroduce the food less frequently than patients allergic to other foods. Girls were found to significantly less frequently reintroduce the food than boys. However, neither the severity of the initial reaction, the anxiety of an accidental reaction during the avoidance diet, nor a prolonged avoidance diet did influence the decision to reintroduce the food. Among other reasons listed, fears of persistence of allergies, with recurrent pruritus or non-specific skin rashes after eating the food, were reported in 12.7% of the total number of questionnaires. Patients who reintroduced the food reported that their social life generally improved. One quarter of previously allergic patients continue a food avoidance diet despite a negative challenge. We suggest reassessing food consumption in all patients after a negative food challenge, and in those still avoiding the specific food to consider a repeated challenge test.

  2. The state of food and agriculture in Islamic countries.

    1986-11-01

    This review of the state of food and agriculture in Islamic countries underlines the need for much greater public commitment to agricultural development. Within the Organization of the Islamic Conference (OIC), 44 member nations, exibiting immense geographic and economic diversity, have come together recently to begin to cooperate on increasing food production. It is difficult to generalize about food production conditions in Islamic nations, but basically, within the OIC, total arable land increased from 159 to 167 ha in the 1970s, a small amount unevenly distributed over the group. Dry-land farming has not received enough public attention, and the dependence on cereals grown under rainfed conditions leaves the population vulnerable to fluctuation. Many of the poorer nations have not given the priority to land improvement that has been successful in Egypt, Pakistan, and some other countries. The economic burden of food imports has become lighter in some countries, although in all it continues to be serious. Net cereal imports to Islamic countries rose from 21 to 39 million tons from 1975-83. An overall increase in the per capita dietary energy supplies masks broad differences between the wealthier and poorer nations of the OIC, and between more and less priviledged populations within the societies. A small proportion of financial commitments to agriculture (15%) come from Islamic community donors; this is not a leading program priority. Often spending has been for large capital-intensive projects depending on imported skills and inputs. As a group, the OIC must plan to take advantage of their technical and environmental diversity, and work together to avoid inefficient dispersal of personnel and other resources. Tabular data show selected indicators of agricultural development (e.g. % of food imported, food production growth), average annual rate of food production change related to population growth, per capita dietary energy supplies, and external assistance

    Affluent diets have negative effects on the health of the population and the environment. Moreover, the ability of industrialised agricultural ecosystems to continue to supply these diets is threatened by the anticipated consequences of climate change. By challenging the ongoing supply the diets of affluent countries, climate change provides a population and environmental health opportunity. This paper contrasts two strategies for dealing with climate change-related food insecurity. Functional foods are being positioned as one response because they are considered a hyper-efficient mechanism for supplying essential micronutrients. An alternative response is civic and urban agriculture. Rather than emphasising increased economic or nutritional efficiencies, civic agriculture presents a holistic approach to food security that is more directly connected to the economic, environmental and social factors that affect diet and health.

    2014-10-01

    Global interest in food policy is emerging in parallel with mounting challenges to the food supply and the rising prevalence of diet-related chronic health conditions. Some of the foundational elements of food policies are agricultural practices, finite resources, as well as economic burdens associated with a growing and ageing population. At the intersection of these interests is the need for policy synchronisation and a better understanding of the dynamics within local, regional and national government decision-making that ultimately affect the wellness of the populous and the safety, quality, affordability and quantity of the food supply. Policies, synchronised or not, need to be implemented and, for the food industry, this has seen a myriad of approaches with respect to condensing complex nutritional information and health claims. These include front and/or back of pack labelling, traffic light systems, etc. but in general there is little uniformity at the more regional and global scales. This translation of the nutritional and health-beneficial messages accompanying specific products to the consumer will undoubtedly be an area of intense activity, and hopefully interaction with policy makers, as the food industry continues to become a more global industry.

  10. World food and agriculture: Outlook for the medium and longer term

    1999-01-01

    The world has been making progress in improving food security, as measured by the per person availability of food for direct human consumption. However, progress has been very uneven, and many developing countries have failed to participate in such progress. In some countries, the food security situation is today worse than 20 years ago. The persistence of food insecurity does not reflect so much a lack of capacity of the world as a whole to increase food production to whatever level would be required for everyone to have consumption levels assuring satisfactory nutrition. The world already produces sufficient food. The undernourished and the food-insecure persons are in these conditions because they are poor in terms of income with which to purchase food or in terms of access to agricultural resources, education, technology, infrastructure, credit, etc., to produce their own food. Economic development failures account for the persistence of poverty and food insecurity. In the majority of countries with severe food-security problems, the greatest part of the poor and food-insecure population depend greatly on local agriculture for a living. In such cases, development failures are often tantamount to failures of agricultural development. Development of agriculture is seen as the first crucial step toward broader development, reduction of poverty and food insecurity, and eventually freedom from excessive economic dependence on poor agricultural resources. Projections indicate that progress would continue, but at a pace and pattern that would be insufficient for the incidence of undernutrition to be reduced significantly in the medium-term future. As in the past, world agricultural production is likely to keep up with, and perhaps tend to exceed, the growth of the effective demand for food. The problem will continue to be one of persistence of poverty, leading to growth of the effective demand for food on the part of the poor that would fall short of that required for

  12. Global food demand and the sustainable intensification of agriculture.

    PubMed

    Tilman, David; Balzer, Christian; Hill, Jason; Befort, Belinda L

    2011-12-13

    Global food demand is increasing rapidly, as are the environmental impacts of agricultural expansion. Here, we project global demand for crop production in 2050 and evaluate the environmental impacts of alternative ways that this demand might be met. We find that per capita demand for crops, when measured as caloric or protein content of all crops combined, has been a similarly increasing function of per capita real income since 1960. This relationship forecasts a 100-110% increase in global crop demand from 2005 to 2050. Quantitative assessments show that the environmental impacts of meeting this demand depend on how global agriculture expands. If current trends of greater agricultural intensification in richer nations and greater land clearing (extensification) in poorer nations were to continue, ~1 billion ha of land would be cleared globally by 2050, with CO(2)-C equivalent greenhouse gas emissions reaching ~3 Gt y(-1) and N use ~250 Mt y(-1) by then. In contrast, if 2050 crop demand was met by moderate intensification focused on existing croplands of underyielding nations, adaptation and transfer of high-yielding technologies to these croplands, and global technological improvements, our analyses forecast land clearing of only ~0.2 billion ha, greenhouse gas emissions of ~1 Gt y(-1), and global N use of ~225 Mt y(-1). Efficient management practices could substantially lower nitrogen use. Attainment of high yields on existing croplands of underyielding nations is of great importance if global crop demand is to be met with minimal environmental impacts.

    Food security is a challenge facing many African-American low-income communities nationally. Community and university partners have established urban agriculture programs to improve access to high quality affordable fruits and vegetables by growing, distributing, and selling food in urban neighborhoods. While the challenge of food security is within communities of color, few studies have described these urban agriculture programs and documented their impact on the crew members who work in the programs and live in the low-income communities. More information is needed on the program impact for crew and community health promotion. Using a survey and focus group discussion from the crew and staff we describe the program and activities of four Chicago Urban Agriculture programs. We summarized the impact these programs have on crew members' perception of urban agriculture, health habits, community engagement, and community health promotion in low-income African-American neighborhoods.

  19. The new political economy of food and agricultural development.

    PubMed

    Mellor, J W; Adams Rh

    1986-11-01

    This paper emphasizes the benefits of an agricultural strategy of development in developing countries. It begins by analyzing the close links between food and employment in the development process. In an underdeveloped country, food production is minimal, but demand is as well because of the small population growth. After development begins, income rises and food demand outstrips production. Only at later stages of development can food production meet demand. The middle stage of development describes most developing countries, which have averaged annual growth rates of 3% per capita in 1966-80. The growth in food demand must be met through technological advance in agriculture: high-yield seeds, fertilizers, and irrigation, which, for example, helped India increase cereal yields 29% between 1954-55 and 1964-65. The rate of growth in cropped areas has declined between 1961-1980, making increased yields more necessary. Growth in employment and income leads to higher food demand, which leads to higher prices and labor costs and a tendency towards capital-intensive agriculture. As the rural sector becomes wealthier, there is also more opportunity for non-agricultural rural workers, creating still more demand. In the final development stage, agricultural products can generate foreign exchange. In Asia, the priority is to ensure efficient outcomes of capital allocations, while in Africa, technology must be instituted. Public investment has been shown to be essential to rapid development in Japan, Taiwan, and the Punjab of India. The absence of this investment in Africa, partly because of an overemphasis on urban sector investment, is largely responsible for the backward state of African agriculture. Often rural areas are overtaxed, agricultural experts are lacking, and there is a growing presence of urban bureaucrats. Both experts in the donor community and farmers themselves must become more vocal in demanding investment in the agricultural sector.

    Conflicting arguments and partial truths on genetically modified (GM) foods have left confusion. Although studies of consumer acceptance of GM foods are numerous, the study of scientists is limited. Therefore, the main objective of this study was to assess the attitudes of scientists towards GM foods. The study was a cross sectional study. A total of 400 scientists (involved in at least one of teaching, research and consultancy) in the Bogor Agricultural Institute, Indonesia were selected randomly from its faculties of agriculture, veterinary, fishery, animal husbandry, forestry, agricultural technology, mathematics and science, and the post graduate department. Data collection was done by face-to-face interview using a structured questionnaire and self-administered questionnaire. The result showed that the majority (72.8%) of the respondents were favorably disposed towards GM foods, 14.8% were neutral, and only 12.5% were against them. The majority (78.3%) stated that they would try GM food if offered. Most (71%) reported that they were aware of the term "GM foods". Only half of the respondents felt that they had a basic understanding about GM foods. However, based on a knowledge test, 69.8% had a good knowledge score. Nearly 50% indicated that they were more exposed to news which supported GM foods. Over 90% said that there should be some form of labeling to distinguish food containing GM ingredients from non-GM foods. Attitudes were significantly associated with willingness to try GM foods if offered, restrictions on GM foods, and exposure to media reports about the pros and cons of GM foods. PMID:17468097

    PubMed

    Bhat, Ramesh V

    2008-01-01

    Scientific and technological developments in the agricultural sectors in the recent past has resulted in increased food production and at the same time led to certain public health concerns. Unseasonal rains at the time of harvest and improper post harvest technology often results in agricultural commodities being contaminated with certain fungi and results in the production of mycotoxins. Consumption of such commodities has resulted in human disease outbreaks. Naturally occurring toxins, inherently present in foods and either consumed as such or mixed up with grains, had been responsible for disease outbreaks. Other possible causes of health concern include the application of various agrochemicals such as pesticides and the use of antibiotics in aquaculture and veterinary practices. Foodborne pathogens entering the food chain during both traditional and organic agriculture pose a challenge to public health. Modern biotechnology, producing genetically modified foods, if not regulated appropriately could pose dangers to human health. Use of various integrated food management systems like the Hazard Analysis and critical control system approach for risk prevention, monitoring and control of food hazards are being emphasized with globalization to minimise the danger posed to human health from improper agricultural practices.

    A study was made of the antimony content in some farm products of plant and animal origin in the zones of wastes of antimony factories and those having nothing to do with antimony processing. The content of antimony was discovered to be elevated in all foods obtained in the zone where antimony factories are located, especially in vegetables with ground fruit. A high antimony content was detected in milk. The content of antimony in a "standard" diet calculated on the basis of maximally allowable concentrations of the metal in foods and in analogous diets containing products of plant and animal origin grown in the Fergana and Chuisk valleys was 0.405, 8.585 and 1.702, respectively. The high proportion of vegetables and fruit in the local diets makes them, apart from milk and dairy products, the main sources of antimony supply to the human body.

    With the human population predicted to reach nine billion by 2050, demand for food is predicted to more than double over this time period, a trend which will lead to increased greenhouse gas (GHG) emissions from agriculture. Furthermore, expansion in food production is predicted to occur primarily in the developing world, where adaptation to climate change may be more difficult and opportunities to mitigate emissions limited. In the establishment of the United Nations Framework Convention on Climate Change (UNFCCC), 'ensuring that food production is not threatened' is explicitly mentioned in the objective of the Convention. However, the focus of negotiations under the Convention has largely been on reducing GHG emissions from energy, and industrial activities and realizing the potential of forestry as a carbon sink. There has been little attention by the UNFCCC to address the challenges and opportunities for the agriculture sector. Since 2006, concerted efforts have been made to raise the prominence of agriculture within the negotiations. The most recent The Intergovernmental Panel on Climate Change report and 'The Emissions Gap Report' by the UNEP highlighted the significant mitigation potential of agriculture, which can help contribute towards keeping global temperature rises below the 2°C limit agreed in Cancun. Agriculture has to be a part of the solution to address climate change, but this will also require a focus on how agriculture systems can adapt to climate change in order to continue to increase food output. However, to effectively realize this potential, systematic and dedicated discussion and decisions within the UNFCCC are needed. UNFCCC discussions on a specific agriculture agenda item started in 2012, but are currently inconclusive. However, Parties are generally in agreement on the importance of agriculture in contributing to food security and employment as well as the need to improve understanding of agriculture and how it can contribute to

    NASA Astrophysics Data System (ADS)

    Rulli, M.; D'Odorico, P.

    2013-12-01

    Most of the human appropriation of freshwater resources is for food production. There is some concern that in the near future the finite freshwater resources available on Earth might not be sufficient to meet the increasing human demand for agricultural products. In the late 1700s Malthus argued that in the long run the humanity would not have enough resources to feed itself. Malthus' analysis, however, did not account for the emergence of technological innovations that could increase the rate of food production. The modern and contemporary history has seen at least three major technological advances that have increased humans' access to food, namely, the industrial revolution, the green revolution, and the intensification of global trade. Here we argue that a fourth revolution has just started to happen. It involves foreign direct investments in agriculture, which intensify the crop yields of potentially highly productive agricultural lands by introducing the use of more modern technologies. The increasing demand for agricultural products and the uncertainty of international food markets has recently drawn the attention of governments and agribusiness firms toward investments in productive agricultural land, mostly in the developing world. The targeted countries are typically located in regions that have remained only marginally utilized because of lack of modern technology. It is expected that in the long run large scale land acquisitions for commercial farming will bring the technology required to close the existing yield gaps. While the extent of the acquired land and the associated appropriation of freshwater resources have been investigated in detail, the amount of food this land can produce and the number of people it could feed still need to be quantified. Here we use a unique dataset of verified land deals to provide a global quantitative assessment of the rates of crop and food appropriation potentially associated with large scale land acquisitions.

    The purpose of this article is to provide nutrition educators with an introduction to a range of considerations and forces that are driving the application of modern biotechnology in the food and fiber sector based on a food systems perspective. In doing so, the following issues are critically assessed: (1) the global debate on how to regulate genetically engineered (GE) foods and crops, (2) cultural differences in public perceptions of GE foods, and (3) evaluation of selected GE traits against the principles of social, economic, and ecological sustainability, including the potential of modern agricultural biotechnology to enhance global food security. Where appropriate, we also review other agricultural technologies and the broader political, social, and economic contexts in which these technologies have been introduced. Finally, we offer recommendations for how multiple stakeholder groups, including policy makers, biotechnology advocates, and nutrition educators, can move toward a more informed dialogue and debate on this issue.

    The United States and the world face serious societal challenges in the areas of food, environment, energy, and health. Historically, advances in plant genetics have provided new knowledge and technologies needed to address these challenges. Plant genetics remains a key component of global food security, peace, and prosperity for the foreseeable future. Millions of lives depend upon the extent to which crop genetic improvement can keep pace with the growing global population, changing climate, and shrinking environmental resources. While there is still much to be learned about the biology of plant–environment interactions, the fundamental technologies of plant genetic improvement, including crop genetic engineering, are in place, and are expected to play crucial roles in meeting the chronic demands of global food security. However, genetically improved seed is only part of the solution. Such seed must be integrated into ecologically based farming systems and evaluated in light of their environmental, economic, and social impacts—the three pillars of sustainable agriculture. In this review, I describe some lessons learned, over the last decade, of how genetically engineered crops have been integrated into agricultural practices around the world and discuss their current and future contribution to sustainable agricultural systems.

    The United States and the world face serious societal challenges in the areas of food, environment, energy, and health. Historically, advances in plant genetics have provided new knowledge and technologies needed to address these challenges. Plant genetics remains a key component of global food security, peace, and prosperity for the foreseeable future. Millions of lives depend upon the extent to which crop genetic improvement can keep pace with the growing global population, changing climate, and shrinking environmental resources. While there is still much to be learned about the biology of plant-environment interactions, the fundamental technologies of plant genetic improvement, including crop genetic engineering, are in place, and are expected to play crucial roles in meeting the chronic demands of global food security. However, genetically improved seed is only part of the solution. Such seed must be integrated into ecologically based farming systems and evaluated in light of their environmental, economic, and social impacts-the three pillars of sustainable agriculture. In this review, I describe some lessons learned, over the last decade, of how genetically engineered crops have been integrated into agricultural practices around the world and discuss their current and future contribution to sustainable agricultural systems.

    It is important that we think about the utilization of the Space food in the space agriculture. In addition, these studies may lead the food problem on the earth on the solution. This study thought about the utilization of the food and thought about doing a stem and the root of vegetables performed water culture of with food. I order Japan Food Research Laboratories to do the nutritional analysis of the root of a lettuce cultivated by water culture. The analysis items were lipid, carbohydrates, energy, protein, water, ash, Na, P, Fe, Ca, K, Mg, Cu, Zn, Mn, vitamin B12, vitamin C, vitamin D, dietary fiber(water soluble or insoluble). Most were water, but, as for the root of the lettuce, it was revealed that it was rich in a mineral (calcium, iron and magnesium).To eat the root of the lettuce will be good nutritional supply of minerals (calcium, iron) in the space life. In the result, water and mineral supply could make good use of in low calorie at loots of the lettuce. We want to think about the utilization of each food more in future.

  7. Continuous Passive Sampling of Solutes from Agricultural Subsurface Drainage Tubes

    Agricultural subsurface tube drain systems play an important role in water and solute transport. One study, focusing on lowland agricultural catchments, showed that subsurface tube drainage contributed up to 80% of the annual discharge and 90% of the annual NO3 load from agricultural fields to the receiving water bodies. Knowledge of e.g. nutrient loads and drainage volumes, based on measurements and modelling, are important for adequate water quality management. Despite the importance of tube drain transport of solutes, monitoring data are scarce. This scarcity is a result of the existing monitoring techniques for flow and contaminant load from tube drains being expensive and labor-extensive. The study presented here aimed at developing a cheap, simple, and robust method to monitor solute loads from tube drains. The method is based on the newly developed Flowcap, which can be attached to existing tube drain outlets and can measure total flow, contaminant load and flow-averaged concentrations of solutes in the drainage. The Flowcap builds on the existing Sorbicell principle, a passive sampling system that measures average concentrations over longer periods of time (days to months) for various compounds. The Sorbicell consists of two compartments permeable to water. One compartment contains an adsorbent and one contains a tracer. When water passes through the Sorbicell the compound of interest is absorbed while a tracer is released. Using the tracer loss to calculate the volume of water that has passed the Sorbicell it is possible to calculate the average concentration of the compound. When mounting Sorbicells in the Flowcap, a flow-proportional part of the drainage is sampled from the main stream. To accommodate the wide range of drainage flow rates two Flowcaps with different capacities were tested in the laboratory: one with a capacity of 25 L min-1 (Q25) and one with a capacity of 256 L min-1 (Q256). In addition, Sorbicells with two different hydraulic

  9. Declining Global Per Capita Agricultural Production and Warming Oceans Threaten Food Security

    Despite accelerating globalization, most people still eat food that was grown locally. Developing countries with weak purchasing power tend to import as little food as possible from global markets, suffering consumption deficits during times of high prices or production declines. Local agricultural production, therefore, is critical to both food security and economic development among the rural poor. The level of local agricultural production, in turn, will be controlled by the amount and quality of arable land, the amount and quality of agricultural inputs (fertilizer, seeds, pesticides, etc.), as well as farm-related technology, practices, and policies. In this paper we discuss several emerging threats to global and regional food security, including declining yield gains that are failing to keep up with population increases, and warming in the tropical Indian Ocean and its impact on rainfall. If yields continue to grow more slowly than per capita harvested area, parts of Africa, Asia, and Central and Southern America will experience substantial declines in per capita cereal production. Global per capita cereal production will potentially decline by 14 percent between 2008 and 2030. Climate change is likely to further affect food production, particularly in regions that have very low yields due to lack of technology. Drought, caused by anthropogenic warming in the Indian and Pacific Oceans, may also reduce 21 st century food availability by disrupting Indian Ocean moisture transports and tilting the 21 st century climate toward a more El Nino-like state. The impacts of these circulation changes over Asia remain uncertain. For Africa, however, Indian Ocean warming appears to have already reduced main growing season rainfall along the eastern edge of tropical Africa, from southern Somalia to northern parts of the Republic of South Africa. Through a combination of quantitative modeling of food balances and an examination of climate change, we present an analysis of

    Background Latinos from agricultural communities have a high prevalence of food insecurity and are at increased risk of obesity and diabetes, yet little is known about the associations between food insecurity and diabetes outcomes. Objective To examine the associations between food insecurity and diabetes outcomes among rural Latinos. Methods Cross-sectional survey with medical chart abstraction of 250 Latinos with diabetes. Primary outcomes are the control of three intermediate diabetes outcomes (hemoglobin A1C ≤ 8.0%, LDL-cholesterol ≤ 100 mg/dl, and blood pressure ≤ 140/90 mmHg), a composite of control of the three, and receipt of 6 processes of care. Secondary outcomes are cost-related medication underuse and participation in self-care activities. Results Fifty-two percent of patients reported food insecurity and one-in-four reported cost-related medication underuse. Patients with food insecurity were more likely to report cost-related medication underuse (adjusted odds ratio [AOR] =2.49; 95% confidence intervals [CI] 1.30, 4.98; p = 0.003); less likely to meet the composite measure for control of the 3 intermediate outcomes (AOR 0.24; 95% CI 0.07, 0.84; p < 0.05), and less likely to receive a dilated eye exam (AOR 0.37; 95% CI 0.18, 0.77; p < 0.05) and annual foot exams (AOR 0.42; 95% CI 0.20, 0.84; p < 0.05) compared to those who were food secure. Conclusion Among this rural Latino population, food insecurity was independently associated with not having control of the intermediate diabetes outcomes captured in the composite measure, not receiving dilated eye and foot exams, and with self-reporting cost-related medication underuse.

    Quality inspection of food and agricultural produce are difficult and labor intensive. Simultaneously, with increased expectations for food products of high quality and safety standards, the need for accurate, fast and objective quality determination of these characteristics in food products continues to grow. However, these operations generally in India are manual which is costly as well as unreliable because human decision in identifying quality factors such as appearance, flavor, nutrient, texture, etc., is inconsistent, subjective and slow. Machine vision provides one alternative for an automated, non-destructive and cost-effective technique to accomplish these requirements. This inspection approach based on image analysis and processing has found a variety of different applications in the food industry. Considerable research has highlighted its potential for the inspection and grading of fruits and vegetables, grain quality and characteristic examination and quality evaluation of other food products like bakery products, pizza, cheese, and noodles etc. The objective of this paper is to provide in depth introduction of machine vision system, its components and recent work reported on food and agricultural produce.

  16. Agricultural policy, food policy, and communicable disease policy.

    PubMed

    Grant, Wyn

    2012-12-01

    Food and agricultural policy is an essential element of a communicable disease policy. The European Union has developed a more systematic and broadly based interest in questions of food safety and animal health and welfare linked to modernization of the Common Agricultural Policy, reflected in a new treaty obligation on animal welfare. Following the bovine spongiform encephalopathy crisis, moves were made to create a European competency, but implementation and enforcement resources reside with the member states. The European Animal Health Strategy is meant to lead to an EU animal health law, but this has already been constrained by fiscal austerity. The development of such a law may lead to a lowest common denominator formula that does little to enhance consumer protection or improve animal welfare. This is an inherent risk with top-down forms of Europeanization; more attention should be paid to lessons to be learned from bottom-up initiatives of the type used to counteract the bovine diarrhea virus. There will always be a tension among what is good policy for reducing the incidence of communicable disease, policy that is popular with EU citizens, and policy that is acceptable to member states.

  17. Phosphorus cycling in Montreal's food and urban agriculture systems.

    2015-01-01

    Cities are a key system in anthropogenic phosphorus (P) cycling because they concentrate both P demand and waste production. Urban agriculture (UA) has been proposed as a means to improve P management by recycling cities' P-rich waste back into local food production. However, we have a limited understanding of the role UA currently plays in the P cycle of cities or its potential to recycle local P waste. Using existing data combined with surveys of local UA practitioners, we quantified the role of UA in the P cycle of Montreal, Canada to explore the potential for UA to recycle local P waste. We also used existing data to complete a substance flow analysis of P flows in the overall food system of Montreal. In 2012, Montreal imported 3.5 Gg of P in food, of which 2.63 Gg ultimately accumulated in landfills, 0.36 Gg were discharged to local waters, and only 0.09 Gg were recycled through composting. We found that UA is only a small sub-system in the overall P cycle of the city, contributing just 0.44% of the P consumed as food in the city. However, within the UA system, the rate of recycling is high: 73% of inputs applied to soil were from recycled sources. While a Quebec mandate to recycle 100% of all organic waste by 2020 might increase the role of UA in P recycling, the area of land in UA is too small to accommodate all P waste produced on the island. UA may, however, be a valuable pathway to improve urban P sustainability by acting as an activity that changes residents' relationship to, and understanding of, the food system and increases their acceptance of composting.

    PATHWAY simulates the transport of radionuclides from fallout through an agricultural ecosystem. The agro-ecosystem is subdivided into several land management units, each of which is used either for grazing animals, for growing hay, or for growing food crops. The model simulates the transport of radionuclides by both discrete events and continuous, time-dependent processes. The discrete events include tillage of soil, harvest and storage of crops,and deposition of fallout. The continuous processes include the transport of radionuclides due to resuspension, weathering, rain splash, percolation, leaching, adsorption and desorption of radionuclides in the soil, root uptake, foliar absorption, growth and senescence of vegetation, and the ingestion assimilation, and excretion of radionuclides by animals. Preliminary validation studies indicate that the model dynamics and simulated values of radionuclide concentrations in several agricultural products agree well with measured values when the model is driven with site specific data on deposition from world-wide fallout.

    The importance of monitoring the quality of vegetables and fruits is prosperity by giving a competitive advantage for producer and providing a more healthy food for consumer. Diffuse Optical Tomography (DOT) is offering the possibility to detect the internal defects of the agricultural produce quality. Fluorescence diffuse optical tomography (FDOT) is the development of DOT, offering the possibilities to improve spatial resolution and to contrast image. The purpose of this research is to compare FDOT and DOT in forward analysis with continuous wave approach. The scattering and absorbing parameters of potatoes are used to represent the real condition. The object was illuminated by the NIR source from some positions on the boundary of object. A set of NIR detector are placed on the peripheral position of the object to measure the intensity of propagated or emitted light. In the simulation, we varied a condition of object then we analyzed the sensitivity of forward problem. The result of this study shows that FDOT has a better sensitivity than DOT and a better potential to monitor internal defects of agricultural produce because of the contrast value between optical and fluorescence properties of agricultural produce normal tissue and defects.

    Latest FAO figures indicate that an estimated 925 million people are undernourished in 2010, representing almost 16% of the population in developing countries. Looking to the future, there are also major challenges ahead from the rapidly changing socio-economic environment (increasing world population and urbanisation, and dietary changes) and climate change. Promoting agriculture in developing countries is the key to achieving food security, and it is essential to act in four ways: to increase investment in agriculture, broaden access to food, improve governance of global trade, and increase productivity while conserving natural resources. To enable the fourth action, the suite of technological options for farmers should be as broad as possible, including agricultural biotechnologies. Agricultural biotechnologies represent a broad range of technologies used in food and agriculture for the genetic improvement of plant varieties and animal populations, characterisation and conservation of genetic resources, diagnosis of plant or animal diseases and other purposes. Discussions about agricultural biotechnology have been dominated by the continuing controversy surrounding genetic modification and its resulting products, genetically modified organisms (GMOs). The polarised debate has led to non-GMO biotechnologies being overshadowed, often hindering their development and application. Extensive documentation from the FAO international technical conference on Agricultural Biotechnologies in Developing Countries (ABDC-10), that took place in Guadalajara, Mexico, on 1-4 March 2010, gave a very good overview of the many ways that different agricultural biotechnologies are being used to increase productivity and conserve natural resources in the crop, livestock, fishery, forestry and agro-industry sectors in developing countries.

    We have been studying the evaluation of food, nutrition and functional substances, in the selected organic materials for useful life-support systems in closed bio-ecosystems for space agriculture on Mars in the future. We have already proposed several species as food materials; cyanobacterium, Nostoc sp. HK-01 and the Japanese cherry tree. Nostoc sp. HK-01 is a terrestrial cyanobacterium which has high tolerances to several space environments. In addition to its high tolerances to serious environments, HK-01 has a high protein content. Total protein per 100 g of the dried colony of Nostoc sp. HK-01 was approximately 50 g. Woody plant materials also have several properties which can be utilized in our habitation environment and as food. We have already found abilities to produce important functional substances for humans in the selected trees. Here, we show the extended results of our experiments.

    A diverse inventory of secondary products arise from processing of agricultural commodities. Societal, economic and physical constraints will curtail traditional disposal methods and create a need for alternatives that conserve, recycle and capitalize on these underutilized resources. Economic viability of some processes or primary products may depend upon practical alternatives for disposing of secondary products. The broad nature of secondary products and the process from which they emanate along with the complex transformations needed for remediation will require the efforts of multidisciplinary teams of scientists to identify creative solutions. Most secondary products have significant nutritional value and could be fed to animals as a means of disposal. However, detailed chemical and biological characterization is needed to determine nutrient concentrations and to ensure safety and efficacy. Feeding studies will be necessary to demonstrate palatability and to determine effects upon animal health and performance. New bioprocessing techniques will be needed to remediate the attributes of some secondary products into more appropriate forms or qualities. The potential for using wash water biosolids as animal food was investigated. Wash water biosolids from a broad cross section of food processing plants were found to be free from pollutants and other harmful entities. Nutrient composition varied considerably within and among different types of food processing plants (i.e., milk vs poultry). However, within a particular plant, variation in mineral concentration of biosolids over several months was quite small. Wash water biosolids from a milk processing plant were found to be free of pollutants and to have nutritional value. Diets containing biosolids were palatable when fed to sheep, cows, turkeys, or swine. Safety and efficacy studies with sheep and swine indicated that feeding up to 20% biosolids did not adversely affect growth, reproduction or survival.

  13. Compound identification: a Journal of Agricultural and Food Chemistry perspective.

    2007-06-13

    This perspective is designed to summarize the standards that authors of manuscripts submitted to the Journal of Agricultural and Food Chemistry are expected to follow in establishing the structures of either new or unknown compounds identified in the course of a study. It is especially important that the molecular formulas of new compounds be determined by either high-resolution mass spectrometry or combustion analysis. All relevant physical, spectroscopic, and spectrometric data should also be reported, so that other research workers have criteria for comparison with compounds that may be isolated in the future. In the case of flavor and aroma constituents, it is not sufficient to depend upon mass spectrometric identifications based solely on comparison with commercial databases. Mass spectra and retention indices on GC stationary phases of different polarities must be determined and the results compared to data for reference compounds and with commercial standards, when available. If geometric or positional isomers may be present, or for chiral compounds, the retention indices of all isomers or enantiomers must be determined. Odor properties or odor thresholds determined by GC-olfactometry may also serve as appropriate tools for compound identification. Adherence to these standards will ensure that processing of manuscripts proceeds expeditiously and that the high standards of the Journal are maintained.

  14. Biotechnologies for the management of genetic resources for food and agriculture.

    2012-01-01

    In recent years, the land area under agriculture has declined as also has the rate of growth in agricultural productivity while the demand for food continues to escalate. The world population now stands at 7 billion and is expected to reach 9 billion in 2045. A broad range of agricultural genetic diversity needs to be available and utilized in order to feed this growing population. Climate change is an added threat to biodiversity that will significantly impact genetic resources for food and agriculture (GRFA) and food production. There is no simple, all-encompassing solution to the challenges of increasing productivity while conserving genetic diversity. Sustainable management of GRFA requires a multipronged approach, and as outlined in the paper, biotechnologies can provide powerful tools for the management of GRFA. These tools vary in complexity from those that are relatively simple to those that are more sophisticated. Further, advances in biotechnologies are occurring at a rapid pace and provide novel opportunities for more effective and efficient management of GRFA. Biotechnology applications must be integrated with ongoing conventional breeding and development programs in order to succeed. Additionally, the generation, adaptation, and adoption of biotechnologies require a consistent level of financial and human resources and appropriate policies need to be in place. These issues were also recognized by Member States at the FAO international technical conference on Agricultural Biotechnologies for Developing Countries (ABDC-10), which took place in March 2010 in Mexico. At the end of the conference, the Member States reached a number of key conclusions, agreeing, inter alia, that developing countries should significantly increase sustained investments in capacity building and the development and use of biotechnologies to maintain the natural resource base; that effective and enabling national biotechnology policies and science-based regulatory frameworks can

    Often the main criticism of foods derived from biotechnology is concerns about food safety. Whereas most present-day biotechnology-derived foods are approximately 99% similar to their non-biotechnology counterparts, the scientific community must ensure the safety of the novel aspects of these foods. The three phases of safety assessment are discussed and the concept of substantial equivalence is explained.

    To protect and secure food resources for the United States, it is crucial to have a method to compare food systems' criticality. In 2007, the U.S. government funded development of the Food and Agriculture Sector Criticality Assessment Tool (FASCAT) to determine which food and agriculture systems were most critical to the nation. FASCAT was developed in a collaborative process involving government officials and food industry subject matter experts (SMEs). After development, data were collected using FASCAT to quantify threats, vulnerabilities, consequences, and the impacts on the United States from failure of evaluated food and agriculture systems. To examine FASCAT's utility, linear regression models were used to determine: (1) which groups of questions posed in FASCAT were better predictors of cumulative criticality scores; (2) whether the items included in FASCAT's criticality method or the smaller subset of FASCAT items included in DHS's risk analysis method predicted similar criticality scores. Akaike's information criterion was used to determine which regression models best described criticality, and a mixed linear model was used to shrink estimates of criticality for individual food and agriculture systems. The results indicated that: (1) some of the questions used in FASCAT strongly predicted food or agriculture system criticality; (2) the FASCAT criticality formula was a stronger predictor of criticality compared to the DHS risk formula; (3) the cumulative criticality formula predicted criticality more strongly than weighted criticality formula; and (4) the mixed linear regression model did not change the rank-order of food and agriculture system criticality to a large degree.

    In the context of recent increases in international food prices, it is hypothesized that in rural communities retaining food production practices is important for protection against food insecurity at both the household and community levels, as well as for protection against the development of poor nutritional outcomes. To investigate this hypothesis, a cross-sectional study of household food security and nutritional status was carried out in a rural community of settled Bedouins in Lebanon comprising 84 households with 474 individuals; this tribe's recent history of settlement in 2 locations that differ by access to land and food production practices provides the context for this study. Food insecurity was found to be highly prevalent (49%) in this Bedouin community and was negatively associated with household food production (P < 0.05) and the consumption of fruits, chicken, meat, and fish (P < 0.05) and positively associated with consumption of cereal products (P < 0.01). This study shows that in small rural communities in a transitional country, sustaining food production may protect from food insecurity. Agricultural livelihood support programs that promote continued involvement in food production at the household and community level, in conjunction with other income-generating activities, may build resilience against food insecurity and improve dietary diversity.

    The semi-continuous anaerobic digestion of food waste was investigated in 1-L and 20-L continuously stirred tank reactors (CSTRs), to identify the optimum operation condition and the methane production of the semi-continuous anaerobic process. Results from a 1-L digester indicated that the optimum organic loading rate (OLR) for semi-continuous digestion is 8 g VS/L/day. The corresponding methane yield and chemical oxygen demand (COD) reduction were 385 mL/g VS and 80.2 %, respectively. Anaerobic digestion was inhibited at high OLRs (12 and 16 g VS/L/day), due to volatile fatty acid (VFA) accumulation. Results from a 20-L digester indicated that a higher methane yield of 423 mL/g VS was obtained at this larger scale. The analysis showed that the methane production at the optimum OLR fitted well with the determined kinetics equation. An obvious decrease on the methane content was observed at the initial of digestion. The increased metabolization of microbes and the activity decrease of methanogen caused by VFA accumulation explained the lower methane content at the initial of digestion.

    Limited attention has been devoted to the cultural and practice competencies needed by occupational therapy and physical therapy professionals who provide services to farming families impacted by chronic health or disability issues. Agricultural occupational safety and health should represent a continuum of services responsive to individuals, families, and agricultural communities across a life span and range of health status changes. Physical rehabilitation professionals have a key role in impacting an agricultural producer's sense of self-efficacy and capacities for returning to agricultural living and work. However, demonstration of competency is essential in providing person-centered rehabilitation services of assessment, evaluation, treatment planning, interventions, referrals, and discharge issues. The paper highlights methods utilized by a state AgrAbility program and a former National AgrAbility Project to develop a model of continuing education programming for occupational and physical therapists that evaluate and treat agricultural workers after acute injury or exacerbation of chronic health conditions.

    Chaulet, C

    1991-01-01

    Available documents, legal texts, press reports, and some contemporary observations and studies are used to assess aspects of Algeria's drive to reform agriculture and food distribution. Algeria, like many other countries, is striving to replace a centralized agricultural and food distribution system with a greater responsiveness to market conditions. This document examines the climatic and physical constraints on agriculture in Algeria, the government role in agriculture and food distribution since independence, the various groups involved in agricultural policy making and production, and recent changes in agricultural policy and development strategies. Lack of cultivable land, a semiarid climate with marked annual variations in rainfall, soil exhaustion and erosion, and competition for land and water from industry and the growing urban population are among the problems besetting agricultural production. Partial collectivization after independence led to progressive development of 2 parallel agricultural systems, a state portion relying ever more heavily on importation of basic foodstuffs to feed a rapidly growing population, and a private or informal sector outside state control and of unknown size that supplied fruits, vegetables and other nonstaples at market rates. The public sector agriculture was not able to become profitable because of the political functions it was required to fill. At the moment of its proposed agricultural reforms, Algeria has neither a solid agricultural base nor a population resigned to inequality. State intervention in food acquisition and distribution has, according to nutritional surveys, resulted in an improved nutritional status almost everywhere in Algeria. Consumers have become an important pressure group. Other groups whose interest would be affected by a new agricultural policy include diverse groups of agricultural producers ranging from salaried workers on large properties to peasants working family holdings, potential

    2013-01-01

    Abstract Nanotechnology offers substantial prospects for the development of state-of-the-art products and applications for agriculture, water treatment, and food industry. Profuse use of nanoproducts will bring potential benefits to farmers, the food industry, and consumers, equally. However, after end-user applications, these products and residues will find their way into the environment. Therefore, discharged nanomaterials (NMs) need to be identified and quantified to determine their ecotoxicity and the levels of exposure. Detection and characterization of NMs and their residues in the environment, particularly in food and agricultural products, have been limited, as no single technique or method is suitable to identify and quantify NMs. In this review, we have discussed the available literature concerning detection, characterization, and measurement techniques for NMs in food and agricultural matrices, which include chromatography, flow field fractionation, electron microscopy, light scattering, and autofluorescence techniques, among others.

    2010-04-01

    Agricultural and food processing industries are always looking to implement real-time quality monitoring techniques as a part of good manufacturing practices (GMPs) to ensure high-quality and safety of their products. Near-infrared (NIR) hyperspectral imaging is gaining popularity as a powerful non-destructive tool for quality analysis of several agricultural and food products. This technique has the ability to analyse spectral data in a spatially resolved manner (i.e., each pixel in the image has its own spectrum) by applying both conventional image processing and chemometric tools used in spectral analyses. Hyperspectral imaging technique has demonstrated potential in detecting defects and contaminants in meats, fruits, cereals, and processed food products. This paper discusses the methodology of hyperspectral imaging in terms of hardware, software, calibration, data acquisition and compression, and development of prediction and classification algorithms and it presents a thorough review of the current applications of hyperspectral imaging in the analyses of agricultural and food products.

    Development of effective food inspection systems is critical in successful implementation of the hazard analysis and critical control points (HACCP) program. Hyperspectral imaging or imaging spectroscopy, which combines techniques of imaging and spectroscopy to acquire spatial and spectral information simultaneously, has great potential in food quality and safety inspection. This paper reviewed the basic principle and features of hyperspectral imaging and its hardware and software implementation. The potential areas of application for hyperspectral imaging in food quality and safety inspection were identified and its limitations were discussed. A hyperspectral imaging system developed for research in food quality and safety inspection was described. Experiments were performed to acquire hyperspectral images from four classes of poultry carcasses: normal, cadaver, septicemia, and tumor. Noticeable differences in the spectra of the relative reflectance and its second difference in the wavelengths between 430 nm and 900 nm were observed between wholesome and unwholesome carcasses. Differences among the three classes of unwholesome carcasses were also observed from their respective spectra. These results showed that hyperspectral imaging can be an effective tool for safety inspection of poultry carcasses.

  19. Urban Intensification and Expansion in Sub-Saharan Africa: Impacts on Urban Agriculture and Food Security

    In Sub-Saharan Africa (SSA), urban intensification and expansion are increasing at alarming rates due to rapid population growth and rural-to-urban migration. This has led to the premise that the proportion of SSA urban residents most vulnerable to food insecurity is the highest in the world. Using a focused survey and multi-temporal (decadal) land use/cover classification of Landsat images, we explored the effect of urban intensification and expansion on urban agriculture and food security, focusing on a megacity and a regional center in Uganda: Kampala and Mbarara, respectively. We found that food insecurity arose due to a number of reasons, among which are: i) expansion and intensification of of urban settlements into previously productive agricultural lands in urban and peri-urban areas; ii) loss of predominantly young (rural agricultural) adult labor force to urban centers, leading to decline in rural food production; iii) lack of proper urban planning incorporating green and agricultural development leading to low productive market garden systems. We discussed these outcomes in light of existing studies which estimated that urban agriculture alone supports over 800 million people globally and accounts for 15-20% of world food supply. In spite of this relatively low contribution by urban/peri-urban agriculture, it probably accounts for higher proportion of food supply to urban poor in SSA and thus are most vulnerable to the loss of urban and peri-urban agricultural land. Further recommendations require policy makers and urban planners to team up to design a suitable framework for sustainable urban planning and development.

  20. Food, Feed, or Fuel? Phosphorus Flows Embodied in US Agricultural Production and Trade

    Agricultural phosphorus (P) use is integral to sustainable food production and water quality regulation. Globalization of agricultural systems, changing diets, and increasing biofuel production pose new challenges for managing non-renewable P reserves, particularly in key agricultural producing regions such as the US. We used a detailed model of the US agricultural system to assess the quantity of mineral P fertilizers used to produce food crops, livestock, and biofuels relative to the P ultimately consumed in domestic diets. We also quantified linkages in fertilizer use between the US and its trading partners globally via agricultural trade. Feed and livestock production drove by far the largest demand for P fertilizers in the US (56% of all P use for domestic and imported products). Of the total mineral P inputs to US domestic agriculture in 2007 (1905 Gg P), 28% were retained in agricultural soils as surplus P, 40% were lost through processing and waste prior to consumption in human diets, while 10% were diverted directly to biofuel production. One quarter of P fertilizer in the US was required to produce exports, particularly major food and feed crops (corn, soybean, and wheat) that drove a large net P flux out of the country (338 Gg P) with strongly crop-specific effects on soil P imbalances nationally. However, US meat consumption involved considerable reliance on P fertilizer use in other countries to produce red meat imports linked primarily to soil P surpluses abroad. We show that changes in domestic farm management and consumer waste could together reduce the P fertilizer needed to produce food consumed in the US by half, which is comparable to the P fertilizer reduction attainable by cutting domestic meat consumption (44%). More effective distribution of P use for major crops nationally and greater recycling of all agricultural wastes is critical to using US phosphate rock reserves as efficiently as possible while maintaining export-oriented agriculture.

    Since its establishment in 1945, the Food and Agriculture Organization of the United Nations (FAO) has worked with member countries to increase food production and food supplies and improve the nutritional well-being of the world population. Dietary assessment is an important component in the process of identifying groups that are nutritionally at risk and in developing appropriate programs and policies to improve nutritional well-being. However, simpler, more cost-effective methods are needed that will allow rapid analysis of survey results so that information can be readily available to policymakers at all levels. FAO continues to work toward development of methods to improve nutrition monitoring and surveillance for developed and developing countries.

    The main directions in food packaging research are targeted toward improvements in food quality and food safety. For this purpose, food packaging providing longer product shelf-life, as well as the monitoring of safety and quality based upon international standards, is desirable. New active packaging strategies represent a key area of development in new multifunctional materials where the use of natural additives and/or agricultural wastes is getting increasing interest. The development of new materials, and particularly innovative biopolymer formulations, can help to address these requirements and also with other packaging functions such as: food protection and preservation, marketing and smart communication to consumers. The use of biocomposites for active food packaging is one of the most studied approaches in the last years on materials in contact with food. Applications of these innovative biocomposites could help to provide new food packaging materials with improved mechanical, barrier, antioxidant, and antimicrobial properties. From the food industry standpoint, concerns such as the safety and risk associated with these new additives, migration properties and possible human ingestion and regulations need to be considered. The latest innovations in the use of these innovative formulations to obtain biocomposites are reported in this review. Legislative issues related to the use of natural additives and agricultural wastes in food packaging systems are also discussed.

    The US Department of Agriculture Food Patterns were updated for the 2010 Dietary Guidelines for Americans to meet new nutrition goals and incorporate results of food pattern modeling requested by the Dietary Guidelines Advisory Committee. The purpose of this article is to describe the process used and changes in the updated patterns. Changes include renaming the Meat and Beans and Milk Groups to the Protein Foods and Dairy Groups, respectively, to be more encompassing of foods in each. Vegetable subgroups now provide more achievable intake recommendations. Calcium-fortified soymilk is now included in the Dairy Group because of its similarity to foods in that group. Increased amounts of seafoods are recommended in the Protein Foods Group, balanced by decreased amounts of meat and poultry. A limit on calories from solid fats and added sugars is included, replacing the previous discretionary calorie allowance and emphasizing the need to choose nutrient-dense forms of foods. Lacto-ovo vegetarian and vegan patterns that meet nutrition goals were created by making substitutions in the Protein Foods Group, and for vegan patterns, in the Dairy Group. Patterns identify food choices that meet nutritional needs within energy allowances and encourage choosing a variety of foods. They rely on foods in nutrient-dense forms, including a limited amount of calories from solid fats and added sugars. The Food Patterns provide a useful template for educating consumers about healthful food choices while highlighting a large gap between choices many Americans make and healthy eating patterns.

    Scanning electron microscopy is a useful tool for understanding food contamination and directing product development of food and industrial products. The current trend in food research is to produce foods that are fast to prepare and/or ready to eat. At the same time, these processed foods must be safe, high quality and maintain all or most of the nutritional value of the original whole foods. Minimally processed foods, is the phrase used to characterize these "new" foods. New techniques are needed which take advantage of minimal processing or processing which enhances the fresh properties and characteristics of whole foods while spending less time on food preparation. The added benefit coupled to less cooking time in an individual kitchen translates to an overall energy savings and reduces the carbon emissions to the environment. Food processing changes the microstructure, and therefore, the quality, texture and flavor, of the resulting food product. Additionally, there is the need to reduce waste, transportation costs and product loss during transportation and storage. Unlike food processing, structural changes are desirable in co-products as function follows form for food packaging films and boxes as well as for building materials and other industrial products. Thus, the standard materials testing procedures are coupled with SEM to provide direction in the development of products from agricultural residues or what would otherwise be considered waste materials. The use of agricultural residues reduces waste and adds value to a currently underutilized or unutilized product. The product might be biodegradable or compostable, thus reducing landfill requirements. Manufacturing industrial and packaging products from biological materials also reduces the amount of petroleum products currently standard in the industry.

    In the wake of growing public concerns over salmonella outbreaks and other highly publicized food safety issues, Congress passed the FDA Food Safety Modernization Act in 2011, which placed more stringent standards on food growing and packaging operations. In negotiations preceding the Act's passage, farmers of local, sustainable food argued that these rules would unduly burden local agricultural operations or, at the extreme, drive them out of business by creating overly burdensome rules. These objections culminated in the addition of the Tester-Hagan Amendment to the Food Safety Modernization Act, which created certain exemptions for small farms. Proposed Food and Drug Administration (FDA) rules to implement the Act threatened to weaken this victory for small farm groups, however, prompting a loud response from small farmers and local food proponents. The FDA's second set of proposed rules, issued in September 2014 in response to these and other complaints, were, perhaps surprisingly, responsive to small farmers' concerns. Using comments submitted to the FDA, this article explores the responses of the agriculture industry and public health organizations, as well as small farm groups, consumers of local food, and sustainable agriculture interests (which, for simplicity, I alternately describe as comprising the "sustainable agriculture" or "small farm" movement), to three aspects of the FDA's proposed rules--involving manure application, on-farm packing activities, and exemptions for very small farms--to assess the strength of the sustainable agriculture movement. The rules involving manure application and on-farm packing, it turns out, reveal little about the independent political strength of the local food movement, as large industry groups also objected to these provisions. But for the third issue discussed here--exemptions for very small farms--the interests of sustainable agriculture groups were directly opposed to both industry and public health organizations

    This paper assesses the relationship between food consumption patterns and the use of agricultural land. First, it calculates the amount of land needed to produce singular foods, and second, it assesses land requirements of food consumption patterns. The paper observes large differences among requirements for specific foods. Especially livestock products, fats, and coffee have large land requirements. The consumption of specific foods can change rapidly over time, causing shifts in land requirements. A rise or fall of requirements, however, depends on the initial consumption pattern. Patterns based on animal foods shifting towards market foods containing more staples require less land. This dietary change direction was shown for Dene/Métis communities in Canada. Patterns based on staples shifting toward diets containing more livestock foods and beverages require more land. This change direction was observed in the Netherlands. Per capita land requirements differ among countries. In Europe, Portugal showed the smallest requirement (1814m2), Denmark the largest (2479m2). The Danish pressure was mainly caused by large consumption of beer, coffee, fats, pork, and butter. The trend toward food consumption associated with affluent life styles will bring with it a need for more land. This causes competition with other claims, such as infrastructural developments or ecological forms of agriculture.

    Urban agriculture provides a potential contribution towards more sustainable food production and mitigating some of the human impacts that accompany volatility in regional and global food supply. When considering the capacity of urban landscapes to produce food products, the impact of urban water demand required for food production in cities is often neglected. Urban agricultural studies also tend to be undertaken at broad spatial scales, overlooking the heterogeneity of urban form that exerts an extreme influence on the urban energy balance. As a result, urban planning and management practitioners require, but often do not have, spatially explicit and detailed information to support informed urban agricultural policy, especially as it relates to potential conflicts with sustainability goals targeting water-use. In this research we introduce a new model, CityCrop, a hybrid evapotranspiration-plant growth model that incorporates detailed digital representations of the urban surface and biophysical impacts of the built environment and urban trees to account for the daily variations in net surface radiation. The model enables very fine-scale (sub-meter) estimates of water footprints of potential urban agricultural production. Results of the model are demonstrated for an area in the City of Vancouver, Canada and compared to aspatial model estimates, demonstrating the unique considerations and sensitivities for current and future water footprints of urban agriculture and the implications for urban water planning and policy.

    Investigation carried out by the Department of Hydraulic Engineering of SGGW in Zagożdżonka River have shown an intensive suspended sediment transport during the winter season, when occurring floods are caused by rainfall and snowmelt as well. The relation between rainfall/snowmelt -runoff - sediment transport have been investigated in small, agricultural catchment in central Poland. The hydrological and meteorological data collected in Zagożdżonka catchment during winter season have been used to calculate lag time of runoff (Lag) and lag time of sediment yield (Lags). Both, Lag and Lags are important characteristics of the instantaneous unit hydrograph (IUH) and instantaneous unit sedimentgraph (IUSG).These characteristics are interrelated. Field data from Zagożdżonka River catchment have been used to demonstrate the relationship between lag times. The results of investigation show that: a) there is a strong relationship between Lag and Lags; b) in most cases the value of a = Lags/Lag is smaller than 1; c) in case of snowmelt floods there was only poor correlation between parameter a and the total runoff depth (water supply). Key words: snowmelt floods, winter season, suspended sediment transport, lag time of runoff and sediment yield

    Agriculturalists in the 21st century will be farming crops in different climates than today. Atmospheric CO{sub 2} will likely exceed 700 {micro}l l{sup {minus}1} by the latter half of the next century, and the mean global temperature has been predicted to be 1.5 to 5.9 C higher than today. Further, the incidence of extreme weather events within a growing season has been predicated to increase. Extreme-weather events often limit crop yields even in today`s environment; e.g., a late spring may severely limit a citrus or winter wheat crop. Agricultural productivity is extremely sensitive to changes projected in the environment, particularly where crops are produced in marginal areas. The authors conducted several studies in which plants were grown in controlled environments with natural radiation levels. Carbon dioxide, water, temperature, and nutrients were each varied independently while the other factors were maintained at nearly optimum conditions. Photosynthesis, transpiration, growth and rate of development were measured. At nearly optimum temperature (26 to 28 C), doubling today`s atmospheric CO{sub 2} concentration results in about 50% increase in biomass production with only trivial changes in the ratio of vegetative to fruit or grain production. However, fruit or grain production is drastically reduced at above-optimum temperatures. The authors examined long-term climatology data from four areas in the US Cotton Belt and a maritime climate, Maros, Indonesia.

    The most important public health priority in agricultural policy-making is currently food safety, despite the relatively higher importance of food security, nutrition, and other agricultural-related health issues in terms of global burden of disease. There is limited experience worldwide of using health impact assessment (HIA) during the development of agriculture and food policies, which perhaps reflects the complex nature of this policy sector. This paper presents methods of HIA used in the Republic of Slovenia, which is conducting a HIA of proposed agricultural and food policies due to its accession to the European Union. It is the first time that any government has attempted to assess the health effects of agricultural policy at a national level. The HIA has basically followed a six-stage process: policy analysis; rapid appraisal workshops with stakeholders from a range of backgrounds; review of research evidence relevant to the agricultural policy; analysis of Slovenian data for key health-related indicators; a report on the findings to a key cross-government group; and evaluation. The experience in Slovenia shows that the HIA process has been a useful mechanism for raising broader public health issues on the agricultural policy agenda, and it has already had positive results for policy formation. HIA is one useful approach to more integrated policy-making across sectors, but clearly it is not the only mechanism to achieve this. A comparison of the approach used in Slovenia with HIA methods in other countries and policy contexts shows that there are still many limitations with HIA application at a government level. Lessons can be learnt from these case studies for future development and application of HIA that is more relevant to policy-makers, and assists them in making more healthy policy choices.

    Sustainable production of agricultural commodities and growth of international trade in these goods are challenged as never before by supply-side constraints (such as climate change, water and land scarcity, and environmental degradation) and by demand-side dynamics (volatility in food and energy markets, the strengthening food-energy linkage, population growth, and income growth). On the one hand, the rapidly expanding demand can potentially create new market opportunities for agriculture. On the other hand, there are many threats to a sufficient response by the supply side to meet this growing and changing demand. Agricultural production systems in many countries are neither resource-efficient, nor producing according to their full potential. The stock of natural resources such as land, water, nutrients, energy, and genetic diversity is shrinking relative to demand, and their use must become increasingly efficient in order to reduce environmental impacts and preserve the planet's productive capacity. World energy prices have increased rapidly in recent years. At the same time, agriculture has become more energy-intensive. Higher energy costs have pushed up the cost of producing, transporting and processing agricultural commodities, driving up commodity prices. Higher energy costs have also affected water use and availability through increased costs of water extraction, conveyance and desalinization, higher demand for hydroelectric power, and increased cost of subsidizing water services. In the meantime, the development of biofuels has diverted increasing amounts of agricultural land and water resources to the production of biomass-based renewable energy. This more "intensified" linkage between agriculture and energy comes at a time when there are other pressures on the world's limited resources. The related high food prices, especially those in the developing countries, have led to setbacks in the poverty alleviation effort among the global community with more

    2008-09-01

    The management of food garbage is of great importance because of its high energy consumption, potential environmental hazards and public health risks. In Taiwan, through the competent authorities at all levels and the citizens' participation in sorting household wastes, many recycling efforts have recently been implemented to further utilize it as available resources such as swine feeds and organic fertilizer by composting. As a result, a total of approximately 570 thousand metric tons was recycled with a recycling ratio of about 21.2% on a basis of food garbage generation in 2006, rising over 22% from a year earlier. These figures showed that compulsory garbage sorting has indeed dramatically increased the recycling of food garbage. The objective of this paper is to present and discuss some management considerations in turning food garbage into agricultural resources due to the compulsory garbage sorting directive in Taiwan. The description first aims at the current status in food garbage generation and its recycling, and at the regulatory polices which have become effective since 2000. It also centers on the environmental and agricultural measures on upgrading food garbage recycling. Based on the preliminary analysis of environmental benefit by the Revised 1996 Intergovernmental Panel on Climate Change (IPCC) Guidelines for National Greenhouse Gas Inventories, it is obvious that composting food garbage is superior to that by traditional treatments (i.e., incineration and sanitary landfill) from the viewpoint of reducing greenhouse gases (i.e., CO(2) and CH(4)) emissions.

    2015-04-01

    More than 70% of fresh water is used in agriculture in many parts of the world, but competition for domestic and industrial water use is intense. For future global food security, water use in agriculture must become sustainable. Agricultural water-use efficiency and water productivity can be improved at different points from the stomatal to the regional scale. A promising approach is the use of deficit irrigation, which can both save water and induce plant physiological regulations such as stomatal opening and reproductive and vegetative growth. At the scales of the irrigation district, the catchment, and the region, there can be many other components to a sustainable water-resources strategy. There is much interest in whether crop water use can be regulated as a function of understanding of physiological responses. If this is the case, then agricultural water resources can be reallocated to the benefit of the broader community. We summarize the extent of use and impact of deficit irrigation within China. A sustainable strategy for allocation of agricultural water resources for food security is proposed. Our intention is to build an integrative system to control crop water use during different cropping stages and actively regulate the plant's growth, productivity, and development based on physiological responses. This is done with a view to improving the allocation of limited agricultural water resources.

    2014-01-01

    The entire food value chain and diet of low and middle income countries (LMICs) are rapidly shifting. Many of the issues addressed by the nutrition community ignore some of the major underlying shifts in purchases of consumer packaged foods and beverages. At the same time, the drivers of the food system at the farm level might be changing. There is a need for the agriculture and nutrition communities to understand these changes and focus on some of their implications for health. This rapid growth of the retail sector will change the diets of the food insecure as much as that of the food secure across rural and urban LMIC’s. This short commentary contents that current research, programs and policies are ignoring these rapid dynamic shifts. PMID:24932059

    The Americas are extremely important as a unique contributor to Food Security. It provides from tropical to temperate crops. Not only they are able to feed their own population, but contribute significantly to the food supply of the population in developed, emergent and underdeveloped countries. This fact has given the region a unique responsibility to develop a regional risk-management strategy to manage food insecurity at a local, national, regional and global level. Although international agencies such as UN Food and Agriculture Organization (FAO), Instituto Interamericano para la Cooperación en Agricultura (IICA) and the regional centres of the Consultative Group for International Agriculture Research (CGIAR) and the World Bank (WB), are engaged in actions for Risk Management in Agriculture for reducing Food Insecurity. However there is a need to build a framework and/or comprehensive regional strategy for the Americas. It would identify areas for promoting research projects where natural and social science work together for producing relevant scientific information and tools i.e. maps, indicators, models and scenarios, early warning systems, etc. to cooperate with both policy and decision makers in the public and private sectors. This would eventually lead to a comprehensive regional programme for reducing food insecurity. The purpose of International Council for Science-International Research and the International Research for Disaster Risk programme (ICSU-IRDR) and ICSU Regional Office for Latinamerica and the Caribbean (ICSU-ROLAC) is to promote the cooperation of the relevant scientific fields in both natural science and social science in a multi and trans-disciplinary approach on risk management to reduce food insecurity. Also both ICSU-IRDR and ICSU-ROLAC are building a case for the inclusion of the scientific community in the revision of the Hjogo Framework for Action for Disaster Reduction to be held in 2015 as risk management for reducing food

    This commentary is a face-to-face debate between two almost opposite positions regarding the application of genetic engineering in agriculture and food production. Seven questions on the potential benefits of the application of genetic engineering in agriculture and on the potentially adverse impacts on the environment and human health were posed to two scientists: one who is sceptical about the use of GMOs in Agriculture, and one who views GMOs as an important tool for quantitatively and qualitatively improving food production.

  20. Agriculture and food systems in sub-Saharan Africa in a 4°C+ world.

    PubMed

    Thornton, Philip K; Jones, Peter G; Ericksen, Polly J; Challinor, Andrew J

    2011-01-13

    Agricultural development in sub-Saharan Africa faces daunting challenges, which climate change and increasing climate variability will compound in vulnerable areas. The impacts of a changing climate on agricultural production in a world that warms by 4°C or more are likely to be severe in places. The livelihoods of many croppers and livestock keepers in Africa are associated with diversity of options. The changes in crop and livestock production that are likely to result in a 4°C+ world will diminish the options available to most smallholders. In such a world, current crop and livestock varieties and agricultural practices will often be inadequate, and food security will be more difficult to achieve because of commodity price increases and local production shortfalls. While adaptation strategies exist, considerable institutional and policy support will be needed to implement them successfully on the scale required. Even in the 2°C+ world that appears inevitable, planning for and implementing successful adaptation strategies are critical if agricultural growth in the region is to occur, food security be achieved and household livelihoods be enhanced. As part of this effort, better understanding of the critical thresholds in global and African food systems requires urgent research. PMID:21115516

    Objective To systematically review the available evidence on whether national or international agricultural policies that directly affect the price of food influence the prevalence rates of undernutrition or nutrition-related chronic disease in children and adults. Design Systematic review. Setting Global. Search strategy We systematically searched five databases for published literature (MEDLINE, EconLit, Agricola, AgEcon Search, Scopus) and systematically browsed other databases and relevant organisational websites for unpublished literature. Reference lists of included publications were hand-searched for additional relevant studies. We included studies that evaluated or simulated the effects of national or international food-price-related agricultural policies on nutrition outcomes reporting data collected after 1990 and published in English. Primary and secondary outcomes Prevalence rates of undernutrition (measured with anthropometry or clinical deficiencies) and overnutrition (obesity and nutrition-related chronic diseases including cancer, heart disease and diabetes). Results We identified a total of four relevant reports; two ex post evaluations and two ex ante simulations. A study from India reported on the undernutrition rates in children, and the other three studies from Egypt, the Netherlands and the USA reported on the nutrition-related chronic disease outcomes in adults. Two of the studies assessed the impact of policies that subsidised the price of agricultural outputs and two focused on public food distribution policies. The limited evidence base provided some support for the notion that agricultural policies that change the prices of foods at a national level can have an effect on population-level nutrition and health outcomes. Conclusions A systematic review of the available literature suggests that there is a paucity of robust direct evidence on the impact of agricultural price policies on nutrition and health.

    2007-11-01

    The quality concern of food and agricultural products has become more and more significant. The related technologies for nondestructive measurement or quality control of food products have been the focus of many researches. Terahertz (THz) radiation, or THz wave, the least explored region of the spectrum, is the electromagnetic wave that lies between mid-infrared and microwave radiation, which has very important research and application values. THz spectroscopy and THz imaging technique are the two main applications of THz wave. During the past decade, THz waves have been used to characterize the electronic, vibrational and compositional properties of solid, liquid and gas phase materials. Recently, THz technology has gained a lot of attention of researchers in various fields from biological spectral analysis to bio-medical imaging due to its unique features compared with microwave and optical waves. In the present paper, the properties of THz wave and its uniqueness in sensing and imaging applications were discussed. The most recent researches on THz technology used in food quality control and agricultural products inspection were summarized. The prospect of this novel technology in agriculture and food industry was also discussed.

    Community supported agriculture (CSA) programs have become a viable source of locally produced foods and represent a new way to increase fruit and vegetable consumption among individuals. Because CSAs represent a way for consumers to acquire healthy foods while providing financial support to local farmers, CSA involvement could reflect, and be related to, greater concern with both health and environmental impact of food choice. As such, the aim of this study was to examine whether ecological attitudes of CSA members could predict food- and sustainability-related behaviours. Using an online survey, respondents answered questions about attitudes towards the environment, as well behaviours related to food purchases, family food preparation, composting, recycling and minimising food-packaging waste. A total of 115 CSA member responses were collected. Ordinary least squares (OLS) multivariate regression analysis was used to investigate the predictive validity of environmental attitudes on measures of behaviours. A large portion of participants reported the amount and variety of fruits and vegetables their households ate increased as a result of joining a CSA program. Ecological sensitivity was a significant predictor of sustainability-related behaviours as well as money spent eating out and times eaten away from home per week. However, it was not predictive of family involvement in home food preparation. PMID:22698977

  11. Carbon and Phosphorus in soil particulate fraction: effect of continuous agriculture, tillage and fertilization

    In Argentinean Pampas region, the practice of intensive agriculture has diminished total organic carbon (TOC) content in soil. This degradation process can impact over phosphorus (P) organic fractions associated to it, and therefore limit soil capacity to provide P through mineralization. Along this line, P content in soil particulate fraction (PF) has been proposed as an index to estimate this capacity. The aims of this work were to evaluate (1) the effect of continuous agriculture, tillage and P fertilization over TOC and P fractions content in soil and PF, and (2) the stability of P-PF as a mineralization index. To this end, a long term experiment initiated in 2001 in Balcarce, Argentina, under continuous agriculture, was analyzed. There, two tillage systems - conventional till (CT) and no till (NT) - and two fertilization treatments - nitrogen (N) and N + P (NP) - were evaluated. Phosphorus rate was 30 kg ha-1 year-1. In each plot, the following parameters were determined in 2002, 2005, 2008 and 2011: TOC, P Bray, total P (Pt), inorganic P (Pi), and organic P (Po) content in the whole soil and in the PF. Also, C supply by residues and P soil balance during the experiment were calculated, and the P sorption capacity was determined in samples from 2011. C supply was greater in CT (7% relative to NT) and in NP (14% relative to N). However, TOC in soil was not modified neither by tillage or fertilization. Even though, C in the PF decreased (3% annually) by the use of continuous agriculture. This reduction was positively associated to the one observed in other soil properties as Pt, Pi and Po in the PF. P fertilization lessened this reduction in Pt (18,9 mg kg-1 in N and 23,1 mg kg-1 in NP in 2011) and Pi (4,2 mg kg-1 in N and 6,2 mg kg-1 in NP in 2011), but not in Po. This indicates that, Po is affected by management practices and, contrary to Pt, is stable to fertilization. Therefore Po can be studied as a potential P mineralization index. The difference among P

    The behaviour of Linear Alkylbenzene Sulfonate (LAS) in agricultural soil is investigated in the laboratory using continuous-flow soil column studies in order to simultaneously analyze the three main underlying phenomena (adsorption/desorption, degradation and transport). The continuous-flow soil column experiments generated the breakthrough curves for each LAS homologue, C10, C11, C12 and C13, and by adding them up, for total LAS, from which the relevant retention, degradation and transport parameters could be estimated, after proposing adequate models. Several transport equations were considered, including the degradation of the sorbate in solution and its retention by soil, under equilibrium and non-equilibrium conditions between the sorbent and the sorbate. In general, the results obtained for the estimates of those parameters that were common to the various models studied (such as the isotherm slope, first order degradation rate coefficient and the hydrodynamic dispersion coefficient) were rather consistent, meaning that mass transfer limitations are not playing a major role in the experiments. These three parameters increase with the length of the LAS homologue chain. The study will provide the underlying conceptual framework and fundamental parameters to understand, simulate and predict the environmental behaviour of LAS compounds in agricultural soils.

    Agriculture has been central to accounts of Thailand's modernisation and the rise of the national development project between the 1940s and the 1970s. However, the role of agriculture in the waning of national development is rarely explored critically in the Thai context. This paper focuses on agriculture and the role of the state in the shift from national development to globalisation. The first part of the paper examines the beginnings of Thailand's modern agricultural sector, before turning to the state-sponsored diversification of agriculture in the 1950s. The paper locates shifting state responses to agriculture in the late 1950s and 1960s in the context of specific political and historical social forces, before exploring the emergence of agri-food exports in the 1970s and the rise of agribusiness in the 1980s and 1990s. The paper concludes by commenting on the significance of the Thai state's role in the national development project and the globalisation project.

The paper locates shifting state responses to agriculture in the late 1950s and 1960s in the context of specific political and historical social forces, before exploring the emergence of agri-food exports in the 1970s and the rise of agribusiness in the 1980s and 1990s. The paper concludes by commenting on the significance of the Thai state's role in the national development project and the globalisation project. PMID:19205119

    Traditional food systems offer a key link between the social and economic resilience of smallholder farmers and pastoralists and the sustainable food and nutrition security of global populations. This paper addresses issues related to socio-cultural diversity and the continuing complex engagement of traditional and modern communities with the plants and animals that sustain them. In light of some of the unhealthful consequences of the 'nutrition transition' to globalized modern diets, the authors define and propose a process for a more successful food system transition that balances agro-biodiversity and processed commodities to support diet diversity, health and social equity alongside sustainable economic growth. We review empirical research in support of practice and policy changes in agriculture, economic development and health domains as well as cross-sectoral and community-based innovation. High-value food crops within domestic and global value chains can be an entry point for smallholders' participation as contributors and beneficiaries of development, while sustainable small farms, as purveyors of environmental and public health services, diversify global options for long-term adaptation in the face of environmental uncertainty.

    One of the current trends of modern analytical chemistry is the miniaturization of the various tools daily used by a large number of researchers. Ultrafast separations, consumption of small amounts of both samples and reagents as well as a high sensitivity and automation are some of the most important goals desired to be achieved. For many years a large number of research laboratories and analytical instrument manufacturing companies have been investing their efforts in this field, which includes miniaturized extraction materials, sample pre-treatment procedures and separation techniques. Among the separation techniques, capillary electromigration methods (which also include CEC), microchip and nano-LC/capillary LC have received special attention. Besides their well-known advantages over other separation tools, the role of these miniaturized techniques in food analysis is still probably in an early stage. In fact, applications in this field carried out by CEC, microchip, nano-LC and capillary LC are only a few when compared with other more established procedures such as conventional GC or HPLC. The scope of this review is to gather and discuss the different applications of such miniaturized techniques in this field. Concerning CE, microchip-CE and CEC works, emphasis has been placed on articles published after January 2007.

    We have been studying the useful life-support system in closed bio-ecosystem for space agriculture. We have already proposed the several species as food material, such as Nostoc sp. HK-01 and Prunnus sp., cyanobacterium and Japanese cherry tree, respectively. The cyanobacterium, Nostoc sp Hk-01, has high tolerances to several space environment. Furthermore, the woody plant materials have useful utilization elements in our habitation environment. The studies of woody plants under a space-environment in the vegetable kingdom have a high contribution to the study of various and exotic environmental responses, too. We have already found that they can produce the important functional substances for human. Here, we will show the evaluation of functional substances in the selected food materials under the possible conditions for space agriculture after cooking.

    Color is an important factor in Agricultural and the Food Industry. Agricultural or prepared food products are often grade by producers and consumers using color parameters. Color is used to estimate maturity, sort produce for defects, but also perform genetic screenings or make an aesthetic judgement. The task of sorting produce following a color scale is very complex, requires special illumination and training. Also, this task cannot be performed for long durations without fatigue and loss of accuracy. This paper describes a machine vision system designed to perform color classification in real-time. Applications for sorting a variety of agricultural products are included: e.g. seeds, meat, baked goods, plant and wood.FIrst the theory of color classification of agricultural and biological materials is introduced. Then, some tools for classifier development are presented. Finally, the implementation of the algorithm on real-time image processing hardware and example applications for industry is described. This paper also presented an image analysis algorithm and a prototype machine vision system which was developed for industry. This system will automatically locate the surface of some plants using digital camera and predict information such as size, potential value and type of this plant. The algorithm developed will be feasible for real-time identification in an industrial environment.

    The agINFRA project (www.aginfra.eu) was a European Commission funded project under the 7th Framework Programme that aimed to introduce agricultural scientific communities to the vision of open and participatory data-intensive science. agINFRA has now evolved into the European hub for data-powered research on agriculture, food and the environment, serving the research community through multiple roles. Working on enhancing the interoperability between heterogeneous data sources, the agINFRA project has left a set of grid- and cloud- based services that can be reused by future initiatives and adopted by existing ones, in order to facilitate the dissemination of agricultural research, educational and other types of data. On top of that, agINFRA provided a set of domain-specific recommendations for the publication of agri-food research outcomes. This paper discusses the concept of the agINFRA project and presents its major outcomes, as adopted by existing initiatives activated in the context of agricultural research and education.

    development in the mid-1960s which required insertion into the world economy, notably through a search for new export sectors. The agricultural sector was assigned 3 functions: producing food as cheaply as possible, increasing the proportion of exportable crops, and substituting some of the foods imported. Brazil evolved in 2 decades from a classic agroexporter to a more complex structure reflecting the semiindustrialized state of the economy. The share of processed agricultural goods increased accordingly. The foods produced for the internal market have been changing at the same time that a new hierarchy of exportable products has evolved. Agricultural policy involved recourse to market mechanisms and cheap credit focused on the south and southeastern regions, large and medium sized producers, and a few products including soy, coffee, sugar cane, and cotton. Just 3% of credits went to the traditional foodstuffs beans and manioc. The most serious consequence of the internationalization of the agricultural economy has been a dangerous increase in the vulnerability of low income groups to world food price fluctuations.

  10. Beyond climate-smart agriculture: toward safe operating spaces for global food systems

    2013-01-01

    Agriculture is considered to be climate-smart when it contributes to increasing food security, adaptation and mitigation in a sustainable way. This new concept now dominates current discussions in agricultural development because of its capacity to unite the agendas of the agriculture, development and climate change communities under one brand. In this opinion piece authored by scientists from a variety of international agricultural and climate research communities, we argue that the concept needs to be evaluated critically because the relationship between the three dimensions is poorly understood, such that practically any improved agricultural practice can be considered climate-smart. This lack of clarity may have contributed to the broad appeal of the concept. From the understanding that we must hold ourselves accountable to demonstrably better meet human needs in the short and long term within foreseeable local and planetary limits, we develop a conceptualization of climate-smart agriculture as agriculture that can be shown to bring us closer to safe operating spaces for agricultural and food systems across spatial and temporal scales. Improvements in the management of agricultural systems that bring us significantly closer to safe operating spaces will require transformations in governance and use of our natural resources, underpinned by enabling political, social and economic conditions beyond incremental changes. Establishing scientifically credible indicators and metrics of long-term safe operating spaces in the context of a changing climate and growing social-ecological challenges is critical to creating the societal demand and political will required to motivate deep transformations. Answering questions on how the needed transformational change can be achieved will require actively setting and testing hypotheses to refine and characterize our concepts of safer spaces for social-ecological systems across scales. This effort will demand prioritizing key

    The bulk analysis of stable isotopes (carbon, nitrogen, sulphur, oxygen and hydrogen) from food staples is a common tool for inferring origin and/or fraud of food products. Many studies have shown that bulk isotope analyses of agricultural products are able to separate large geographical areas of food origin. However, in micro-localities (regions, districts, and small ranges) these general applications fail in precision and discriminative power. The application of compound specific analysis of specific components of food products helps to increase the precision of established models. Compound groups like fatty acids (FAMEs), vitamins or amino acids can help to add further detailed information on physiological pathways and local conditions (micro-climate, soil, water availability) and therefore might add further information for the separation of micro-localities. In this study we are aiming to demonstrate the power and surplus of information of compound specific isotope analysis in comparison to bulk analysis of agricultural products (e.g. olive oil, cereal crops or similar products) and discuss the advantages and disadvantages of such (labor intense) analysis methods. Here we want to identify tools for further detailed analysis of specific compounds with high powers of region separation for better prediction models.

    Nanomaterials in agriculture and food are key issues of public and regulatory interest. Over the past ten years, patents for nanotechnological applications in the field of food and agriculture have become abundant. Uncertainty prevails however regarding their current development status and presence in the consumer market. Thus, the discussion on nanotechnologies in the food sector with its specific public perception of benefits and risks and the patterns of communication are becoming similar to the debate on genetically modified organisms. The food industry's silence in communication increased mistrust of consumer organisations and policy makers. The article discusses the background of the current regulatory debates, starting with the EU recommendation for defining nanomaterials, provides an overview of possible fields of application in agriculture and food industries and discusses risk assessment and the public debate on benefits and risks. Communicative recommendations are directed at researchers, the food industry and regulators in order to increase trust both in stakeholders, risk management and regulatory processes.

     The increasing food and water demands of East Africa's growing population are stressing the region's inconsistent water resources and rain-fed agriculture. More accurate seasonal agricultural drought forecasts for this region can inform better water and agricultural management decisions, support optimal allocation of the region's water resources, and mitigate socio-economic losses incurred by droughts and floods. Here we describe the development and implementation of a seasonal agricultural drought forecast system for East Africa (EA) that provides decision support for the Famine Early Warning Systems Network's science team. We evaluate this forecast system for a region of equatorial EA (2° S to 8° N, and 36° to 46° E) for the March-April-May growing season. This domain encompasses one of the most food insecure, climatically variable and socio-economically vulnerable regions in EA, and potentially the world: this region has experienced famine as recently as 2011. To assess the agricultural outlook for the upcoming season our forecast system simulates soil moisture (SM) scenarios using the Variable Infiltration Capacity (VIC) hydrologic model forced with climate scenarios for the upcoming season. First, to show that the VIC model is appropriate for this application we forced the model with high quality atmospheric observations and found that the resulting SM values were consistent with the Food and Agriculture Organization's (FAO's) Water Requirement Satisfaction Index (WRSI), an index used by FEWS NET to estimate crop yields. Next we tested our forecasting system with hindcast runs (1993–2012). We found that initializing SM forecasts with start-of-season (5 March) SM conditions resulted in useful SM forecast skill (> 0.5 correlation) at 1-month, and in some cases at 3 month lead times. Similarly, when the forecast was initialized with mid-season (i.e. 5 April) SM conditions the skill until the end-of-season improved. This shows that early-season rainfall

    Global demands on agricultural lands are ever increasing as a result of population growth, changes in diet and increasing biofuel use. By mid-century, the demands for food and fiber are expected to roughly double with the population reaching 9.5 billion. However, earth's finite resource base places a ceiling on the amount of agricultural production that is possible. Several strategies have been widely discussed to meet these rapid increases and to extend the ceiling yet higher, including reducing waste, modifying diets, improving yield and productivity and expanding agriculture and aquaculture. One of the most promising of these is closing the yield gap of currently under-performing agricultural land that has the potential to be much more productive. With high inputs (e.g. irrigation, fertilizers), this strategy has real potential to increase food security, particularly in the developing world where population is expected to sharply increase and where a high potential for yield gap closure exists. Thus it is important to consider whether improvements in global yield can adequately meet global dietary demand during the 21st century. Constructing yield projections to the end of the century, we examine whether global crop production for 154 countries and 16 major food crops under selected agricultural and dietary scenarios can keep pace with estimates of population growth to 2100. By calculating the global production of calories, we are then able to examine how many people can be supported under future scenarios and how closing yield gaps can increase this potential. Our findings agree with previous studies that closing the yield gap alone cannot provide sufficient production by mid-century and that a heavy global dependence on trade will persist throughout the century. Using high-resolution global land suitability maps under a suite of climate models, we find that scenarios incorporating a combination of yield gap closure and agricultural expansion provide the most

    Continuous flow microwave sterilization is an emerging technology that has the potential to replace the conventional heating processes for viscous and pumpable food products. Dielectric properties of pumpable food products were measured by a new approach (under continuous flow conditions) at a temperature range of 20 to 130 degrees C and compared with those measured by the conventional approach (under static conditions). The food products chosen for this study were skim milk, green pea puree, carrot puree, and salsa con queso. Second-order polynomial correlations for the dependence of dielectric properties at 915 MHz of the food products on temperature were developed. Dielectric properties measured under static and continuous flow conditions were similar for homogeneous food products such as skim milk and vegetable puree, but they were significantly different for salsa con queso, which is a multiphase food product. The results from this study suggest that, for a multiphase product, dielectric properties measured under continuous flow conditions should be used for designing a continuous flow microwave heating system.

    The GEOGLAM Crop Monitor's Crop Assessment Tool was released in August 2013 in support of the GEOGLAM Crop Monitor's objective to develop transparent, timely crop condition assessments in primary agricultural production areas, highlighting potential hotspots of stress/bumper crops. The Crop Assessment Tool allows users to view satellite derived products, best available crop masks, and crop calendars (created in collaboration with GEOGLAM Crop Monitor partners), then in turn submit crop assessment entries detailing the crop's condition, drivers, impacts, trends, and other information. Although the Crop Assessment Tool was originally intended to collect data on major crop production at the global scale, the types of data collected are also relevant to the food security and rangelands monitoring communities. In line with the GEOGLAM Countries at Risk philosophy of "foster[ing] the coordination of product delivery and capacity building efforts for national and regional organizations, and the development of harmonized methods and tools", a modified version of the Crop Assessment Tool is being developed for the USAID Famine Early Warning Systems Network (FEWS NET). As a member of the Countries at Risk component of GEOGLAM, FEWS NET provides agricultural monitoring, timely food security assessments, and early warnings of potential significant food shortages focusing specifically on countries at risk of food security emergencies. While the FEWS NET adaptation of the Crop Assessment Tool focuses on crop production in the context of food security rather than large scale production, the data collected is nearly identical to the data collected by the Crop Monitor. If combined, the countries monitored by FEWS NET and GEOGLAM Crop Monitor would encompass over 90 countries representing the most important regions for crop production and food security.

  18. Contribution of anthropogenic phosphorus to agricultural soil fertility and food production

    2014-07-01

    Agricultural intensification over the last few decades has been accompanied by the extensive use of anthropogenic phosphorus (P) derived from mined phosphate rock. Given the increasing scarcity of P resources, accurate estimates of the reliance of agriculture on anthropogenic P are required. Here we propose a modeling approach for assessing the contribution of anthropogenic P to agricultural soil fertility and food production. We performed computations at country level, and France was chosen as a typical western European country with intensive agriculture. Four soil P pools were identified based on their bioavailability (labile versus stable) and origin (anthropogenic versus natural). Pool evolution between 1948 and 2009 was estimated by combining international databases and a simple biogeochemical model. An optimization procedure demonstrated the necessity of representing a stable P pool capable of replenishing the labile pool within 14 to 33 years in order to match country-scale observations. Mean simulated P pool sizes for 2009 (0-35 cm soil horizon) were 146, 616, 31, and 156 kgP/ha for natural stable, anthropogenic stable, natural labile, and anthropogenic labile pools, respectively. We found that, on average, 82% (min-max: 68-91%) of soil P (sum of labile and above defined stable) in that year was anthropogenic. The temporal evolution of this contribution is directly related to the integral of chemical fertilizer use over time, starting from 1948. The contribution of anthropogenic P to food production was similar at 84% (min-max: 72-91%), which is greater than budget-based estimates (~50-60%) commonly reported in the literature. By focusing on soil fertility and food production, this study provides a quantitative estimation of human perturbations of the P cycle in agroecosystems.

    Many industrial products and functional foods can be obtained from cheap and renewable raw agricultural materials. For example, starch can be converted to bioethanol as biofuel to reduce the current demand for petroleum or fossil fuel energy. On the other hand, starch can also be converted to useful functional ingredients, such as high fructose and high maltose syrups, wine, glucose, and trehalose. The conversion process involves fermentation by microorganisms and use of biocatalysts such as hydrolases of the amylase superfamily.

    Many industrial products and functional foods can be obtained from cheap and renewable raw agricultural materials. For example, starch can be converted to bioethanol as biofuel to reduce the current demand for petroleum or fossil fuel energy. On the other hand, starch can also be converted to useful functional ingredients, such as high fructose and high maltose syrups, wine, glucose, and trehalose. The conversion process involves fermentation by microorganisms and use of biocatalysts such as hydrolases of the amylase superfamily.

    Greenhouse gas (GHG) emissions from agriculture could be mitigated from both supple side and demand side. Assessing carbon footprint (CF) of agricultural production and food consumption could provide insights into the contribution of agriculture to climate change and help to identify possible GHG mitigation options. In the present study, CF of China's agricultural production was firstly assessed from site scale to national scale, and from crop production to livestock production. Data for the crop and livestock production were collected from field survey and national statistical archive, and both life cycle assessment and input-output method were employed in the estimations. In general, CF of crop production was lower than that of livestock production on average. Rice production ranked the highest CF in crop production, and the highest CFs of livestock production were observed in mutton and beef production. Methane emissions from rice paddy, emissions from fertilizer application and water irrigation exerted the largest contribution of more than 50% for CF of crop production; however, emissions from forage feeding, enteric fermentation and manure treatment made the most proportion of more than 90 % for CF of livestock production. In China, carbon efficiency was shown in a decreasing trend in recent years. According to the present study, overuse of nitrogen fertilizer caused no yield effect but significant emissions in some sites and regions of China, and aggregated farms lowered the CFs of crop production and livestock production by 3% to 25% and 6% to 60% respectively compared to household farms. Given these, improving farming management efficiency and farm intensive development is the key strategy to mitigate climate change from supply side. However, changes in food consumption may reduce GHG emissions in the production chain through a switch to the consumption of food with higher GHG emissions in the production process to food with lower GHG emissions. Thus, CFs

    Soil plays a central role in food safety as it determines the possible composition of food and feed at the root of the food chain. However, the quality of soil resources as defined by their potential impact on human health by propagation of harmful elements through the food chain has been poorly studied in Europe due to the lack of data of adequate detail and reliability. The European Union's first harmonized topsoil sampling and coherent analytical procedure produced trace element measurements from approximately 22,000 locations. This unique collection of information enables a reliable overview of the concentration of heavy metals, also referred to as metal(loid)s including As, Cd, Cr, Cu, Hg, Pb, Zn, Sb. Co, and Ni. In this article we propose that in some cases (e.g. Hg and Cd) the high concentrations of soil heavy metal attributed to human activity can be detected at a regional level. While the immense majority of European agricultural land can be considered adequately safe for food production, an estimated 6.24% or 137,000km(2) needs local assessment and eventual remediation action.

    As the second largest amounts of COD discharged in 41 kinds of industrial wastewater, it is of great urgency for the agricultural and food processing industry to control water pollution and reduce pollutants. Generally the agricultural and food processing industrial wastewater with high strength COD of 8 000-30 000 mg x L(-1), is mainly treated with anaerobic and aerobic processes in series, but which exists some issues of long process, difficult maintenance and high operational costs. Through coupling anaerobic digestion and membrane separation together, anaerobic membrane bioreactor (AnMBR) has typical advantages of high COD removal efficiency (92%-99%), high COD organic loading rate [2.3-19.8 kg x (m3 x d)(-1)], little sludge discharged (SRT > 40 d) and low cost (HRT of 8-12 h). According to COD composition of high strength industrial wastewater, rate-limiting step of methanation could be either hydrolysis and acidification or methanogenesis. Compared with aerobic membrane bioreactor (MBR), membrane fouling of AnMBR is more complicated in characterization and more difficult in control. Measures for membrane fouling control of AnMBR are almost the same as those of MBR, including cross flow, air sparging and membrane relaxation. For meeting discharging standard of food processing wastewater with high strength, AnMBR is a promising technology with very short process, by enhancing COD removal efficiency, controlling membrane fouling and improving energy recovery.

    The laboratory activity of the Ministry of Agriculture, Livestock and Food Supply in Brazil has a history that is richer than most people are aware of. The institutions that today are known as National Agricultural Laboratory - Lanagros - were once a smaller initiative that suffered ups and downs throughout the decades. The recognition that the Lanagros have today - as reference centres with open communication channels with some of the world's greater laboratories in residue and contaminants in food analyses - is the fruit of several years of hard work, good ideas and a strong will never to let down society. Today the Lanagros act not only by performing analyses for the monitoring and investigation programmes, but also in the research and development of analytical methods, providing technical advice on the elaboration of guidelines and normatives, international negotiation and the evaluation of other laboratories. The Lanagros work in an ISO 17025 environment, and they are now being directed and prepared to be able to respond to outbreaks and crises related to the presence of residues and contaminants in food, with the readiness, quickness and reliability that an emergency requires. Investments are allocated strategically and have been giving concrete results, all to the benefit of consumers. PMID:22087508

    Agricultural food production and agriculturally-related change in land use substantially contribute to greenhouse-gas emissions worldwide. Four-fifths of agricultural emissions arise from the livestock sector. Although livestock products are a source of some essential nutrients, they provide large amounts of saturated fat, which is a known risk factor for cardiovascular disease. We considered potential strategies for the agricultural sector to meet the target recommended by the UK Committee on Climate Change to reduce UK emissions from the concentrations recorded in 1990 by 80% by 2050, which would require a 50% reduction by 2030. With use of the UK as a case study, we identified that a combination of agricultural technological improvements and a 30% reduction in livestock production would be needed to meet this target; in the absence of good emissions data from Brazil, we assumed for illustrative purposes that the required reductions would be the same for our second case study in São Paulo city. We then used these data to model the potential benefits of reduced consumption of livestock products on the burden of ischaemic heart disease: disease burden would decrease by about 15% in the UK (equivalent to 2850 disability-adjusted life-years [DALYs] per million population in 1 year) and 16% in São Paulo city (equivalent to 2180 DALYs per million population in 1 year). Although likely to yield benefits to health, such a strategy will probably encounter cultural, political, and commercial resistance, and face technical challenges. Coordinated intersectoral action is needed across agricultural, nutritional, public health, and climate change communities worldwide to provide affordable, healthy, low-emission diets for all societies.

    The European Union Food Distribution programme for the Most Deprived Persons (MDP) of the community ran from 1987 until 2013. It was funded from Common Agricultural Policy budgets. The programme initially made use of surplus foods from the food mountains resulting from intervention stocks. This food was then distributed through aid agencies within member states, coordinated at a national government level. Reform of the CAP and global rises in food prices resulted in an increase in budget from €300 to €500 million Euros in 2010 with the added power to buy food on the open market. This led to a formal challenge to the scheme on the basis that buying goods on the open market shifted the emphasis from an agricultural/financial basis to a social one. A court ruling found that because the program was no longer used for removing surpluses the link to agriculture policy has become tenuous and therefore had no basis in community law. As a result of this legal challenge a number of policy compromises ensured the MDP would continue until the end of 2013 with a reduced budget. The scheme has been superseded by a new scheme in March 2014 called the Fund for European Aid to the Most Deprived (FEAD). This is seen as a social programme. The way that policy and politics developed and changed the MDP programme are set out. The article tracks its move from being an agricultural policy to a social welfare one.

    Phosphorus fluxes in streams are subjected to high temporal variations, questioning the relevance of the monitoring strategies (generally monthly sampling) chosen to assist EU Directives to capture phosphorus fluxes and their variations over time. The objective of this study was to estimate the annual and seasonal P flux uncertainties depending on several monitoring strategies, with varying sampling frequencies, but also taking into account simultaneous and continuous time-series of parameters such as turbidity, conductivity, groundwater level and precipitation. Total Phosphorus (TP), Soluble Reactive Phosphorus (SRP) and Total Suspended Solids (TSS) concentrations were surveyed at a fine temporal frequency between 2007 and 2015 at the outlet of a small agricultural catchment in Brittany (Naizin, 5 km2). Sampling occurred every 3 to 6 days between 2007 and 2012 and daily between 2013 and 2015. Additionally, 61 storms were intensively surveyed (1 sample every 30 minutes) since 2007. Besides, water discharge, turbidity, conductivity, groundwater level and precipitation were monitored on a sub-hourly basis. A strong temporal decoupling between SRP and particulate P (PP) was found (Dupas et al., 2015). The phosphorus-discharge relationships displayed two types of hysteretic patterns (clockwise and counterclockwise). For both cases, time-series of PP and SRP were estimated continuously for the whole period using an empirical model linking P concentrations with the hydrological and physic-chemical variables. The associated errors of the estimated P concentrations were also assessed. These « synthetic » PP and SRP time-series allowed us to discuss the most efficient monitoring strategies, first taking into account different sampling strategies based on Monte Carlo random simulations, and then adding the information from continuous data such as turbidity, conductivity and groundwater depth based on empirical modelling.

    Agricultural development projects have been promoted in many places as a feature of poverty-reduction strategies. Such projects have often been implemented without a strong in-built education component, and hence have had little success. Agricultural projects seek to improve food security by diversifying a household's resource base and facilitating the social and economic empowerment of women. The present study presents a survey designed to assess the relationship between education level and ability to benefit from dairy-development projects in Kenya. Results reveal higher occupation and employment levels among beneficiary than non-beneficiary households. On the other hand, beneficiaries of poverty-reduction schemes require specialized training. Apart from project-specific training, the level of general education alone cannot predict the attainment of project objectives.

    During the last three decades, the expansion of irrigation using both surface water and groundwater resources has had an important positive impact on Syria’s agricultural production. It is an example of success in achieving food policy objectives, but it has also introduced the challenge of groundwater sustainability. This paper examines the trends in groundwater abstraction for irrigation and the effect of government policies, including input subsidies - such as the diesel fuel subsidy and the crop procurement price support. The fuel subsidy is an important driving force in groundwater depletion and over-abstraction. This analysis examines the interaction between policy signals and the use and allocation of water by farmers. The rapid decline in groundwater resources shows the limitations of this agricultural development strategy and questions its sustainability unless policies change and the rate of abstraction is changed so as not exceed the recharge rate.

    Cultivated area in small plot agriculture in Africa is estimated using a synergetic approach based on multi-sensor, multi-temporal Synthetic Aperture Radar (SAR) data. The method - which is based on the utilization of ALOS PALSAR-1, Cosmo-SkyMed, ENVISAT ASAR data involving different processing techniques - consists in the generation of three independent and complementary products, which in turn they are fused, enabling the generation of the cultivated area. Each intermediate product has a clear meaning within agriculture and food security: i) the potential crop extent prior to the crop season; ii) the potential area at start of the crop season; iii) the crop growth extent during the rainfed crop season. The proposed methodology has been implemented and demonstrated in Malawi. The obtained results show an overall accuracy exceeding 90%.

    The range of social and ethical concerns that have been raised in connection with food and agricultural biotechnology is exceedingly broad. Many of these deal with risks and possible outcomes that are not unique to crops or animals developed using recombinant DNA. Food safety, animal welfare, socio-economic and environmental impacts, as well as shifts in power relations or access to technology raise concerns that might be generalized to many technologies. These aspects of the controversy over biotechnology are analyzed below as elements of general technological ethics, and key norms or values pertinent to each of these categories are specified in some detail. However, a number of special concerns unique to the use of rDNA in manipulating plant and animal genomes have been raised, and these are reviewed as well. The chapter concludes by reviewing two broad policy strategies for responding to the issues, one involving labels and consumer consent, the other applying the precautionary principle.

The impact from these changes wi ll affect the viability of both dryland subsistence and irrigated commodity food production (Knox, et al., 2010a). Since climate is a primary determinant of agricultural productivity, any changes will influence not only crop yields, but also the hydrologic balances, and supplies of inputs to managed farming systems as well as potentially shifting the geographic location for specific crops . Unless concerted and collective action is taken, society risks worldwide food shortages, scarcity of water resources and insufficient energy. This has the potential to unleash public unrest, cross-border conflicts and migration as people flee the worst-affected regions to seck refuge in "safe havens", a situation that Beddington described as the "perfect storm" (2010).

    Antimicrobial peptides (AMPs) are produced by a wide range of organisms and serve as their natural defenses against infection caused by bacteria, viruses and fungi. Because of the positively charge and amphipathic structure, AMPs kill target cells through diverse and complex mechanisms once in a target membrane and these special mechanisms are considered to be the critical factors for the less tendency of drug resistance development. Thus AMPs may become a new generation of promising antimicrobial agents in future anti-infection application. Additionally, AMPs can also be used in food industry and agriculture. On the basis of discussing the structural features, action mechanisms and sources, the applications of AMPs were reviewed in this paper, including in food industry, feedstuff, cultivation of disease-resistant transgenic plant, cultivation of transgenic animal, and aquaculture, especially the patented applications.

    While there has been a number of consumers' studies looking at factors that influence individuals' attitudes and behavior toward GM foods, few studies have considered agricultural professionals' intentions in this regard. This study illuminates agricultural professionals' insights toward GM foods in Southwest Iran. A random sample of 262 respondents was studied. The results indicated that the majority of the respondents had little knowledge about GM foods. They perceived few benefits or risks of GM foods. Their perceived benefits and trust in individuals and institutions had positive impacts on the behavioral intentions of the agricultural professionals. The results also revealed that the low knowledge level of the respondents had a negative impact on the behavioral intentions toward GM foods. This state of affairs is problematic, either GM foods have serious problems or the knowledge conveyed to the Iranian agricultural experts is inappropriate. We recommend a well defined communication strategy to provide information in such a way that allows individuals to feel adequately informed about GM foods. Furthermore, the development of trust and knowledge regarding GM foods can be greater when risk analysis frameworks are transparent, risk assessment methodologies are objective, all stakeholders are engaged in the risk management process, and risk communication focuses on consumers.

    Most global strategies for future food security focus on sustainable intensification of production of food and involve increased use of nitrogen fertilizer and manure. The external costs of current high nitrogen (N) losses from agriculture in the European Union, are 0.3-1.9% of gross domestic product (GDP) in 2008. We explore the potential of sustainable extensification for agriculture in the EU and The Netherlands by analysing cases and scenario studies focusing on reducing N inputs and livestock densities. Benefits of extensification are higher local biodiversity and less environmental pollution and therefore less external costs for society. Extensification also has risks such as a reduction of yields and therewith a decrease of the GDP and farm income and a smaller contribution to the global food production, and potentially an i0ncrease of global demand for land. We demonstrate favourable examples of extensification. Reducing the N fertilization rate for winter wheat in Northwest Europe to 25-30% below current N recommendations accounts for the external N cost, but requires action to compensate for a reduction in crop yield by 10-20%. Dutch dairy and pig farmers changing to less intensive production maintain or even improve farm income by price premiums on their products, and/or by savings on external inputs. A scenario reducing the Dutch pig and poultry sector by 50%, the dairy sector by 20% and synthetic N fertilizer use by 40% lowers annual N pollution costs by 0.2-2.2 billion euro (40%). This benefit compensates for the loss of GDP in the primary sector but not in the supply and processing chain. A 2030 scenario for the EU27 reducing consumption and production of animal products by 50% (demitarean diet) reduces N pollution by 10% and benefits human health. This diet allows the EU27 to become a food exporter, while reducing land demand outside Europe in 2030 by more than 100 million hectares (2%), which more than compensates increased land demand when

    GMO crops were introduced for commercial production in 1996. Since then, their use has increased rapidly. GMOs have primarily benefited large farms and multinational companies in Industrialised Countries and now is more and more debating their utilisation in Developing World. The objective of the present review is an analysis of this subject from a comprehensive point of view; in addition to that, the changes related to the nutritional content of transgenic foods will be treated. Despite the progress that has been made, the world food situation is still marked by mass hunger and chronic malnutrition. In particular micronutrient malnutrition, that means vitamin and mineral deficiencies, represents an important public health problem in several areas of the world. The "golden rice" bioengineered to contain beta-carotene, as a source of vitamin A is the most famous example of GM food used for reduction (or even to solve) of a public health problem. The expected results of this approach have presently not been achieved. Further studies are necessary to increase the general knowledge about GMOs and their long-term effects on human health. Collaborative attitude of different research sectors (private and public) and involvement of different sectors of society will be an added value for comprehension of the real impact of the application of modern biotechnology to food and agriculture systems.

    Farming transformed societies globally. Yet, despite more than a century of research, there is little consensus on the speed or completeness of this fundamental change and, consequently, on its principal drivers. For Northern Europe, the debate has often centered on the rich archaeological record of the Western Baltic, but even here it is unclear how quickly or completely people abandoned wild terrestrial and marine resources after the introduction of domesticated plants and animals at ∼4000 calibrated years B.C. Ceramic containers are found ubiquitously on these sites and contain remarkably well-preserved lipids derived from the original use of the vessel. Reconstructing culinary practices from this ceramic record can contribute to longstanding debates concerning the origins of farming. Here we present data on the molecular and isotopic characteristics of lipids extracted from 133 ceramic vessels and 100 carbonized surface residues dating to immediately before and after the first evidence of domesticated animals and plants in the Western Baltic. The presence of specific lipid biomarkers, notably ω-(o-alkylphenyl)alkanoic acids, and the isotopic composition of individual n-alkanoic acids clearly show that a significant proportion (∼20%) of ceramic vessels with lipids preserved continued to be used for processing marine and freshwater resources across the transition to agriculture in this region. Although changes in pottery use are immediately evident, our data challenge the popular notions that economies were completely transformed with the arrival of farming and that Neolithic pottery was exclusively associated with produce from domesticated animals and plants.

  9. Arsenic behaviour from groundwater and soil to crops: impacts on agriculture and food safety.

    2007-01-01

    High levels of As in groundwater commonly found in Bangladesh and other parts of Asia not only pose a risk via drinking water consumption but also a risk in agricultural sustainability and food safety. This review attempts to provide an overview of current knowledge and gaps related to the assessment and management of these risks, including the behaviour of As in the soil-plant system, uptake, phytotoxicity, As speciation in foods, dietary habits, and human health risks. Special emphasis has been given to the situation in Bangladesh, where groundwater via shallow tube wells is the most important source of irrigation water in the dry season. Within the soil-plant system, there is a distinct difference in behaviour of As under flooded conditions, where arsenite (AsIII) predominates, and under nonflooded conditions, where arsenate (AsV) predominates. The former is regarded as most toxic to humans and plants. Limited data indicate that As-contaminated irrigation water can result in a slow buildup of As in the topsoil. In some cases the buildup is reflected by the As levels in crops, in others not. It is not yet possible to predict As uptake and toxicity in plants based on soil parameters. It is unknown under what conditions and in what time frame As is building up in the soil. Representative phytotoxicity data necessary to evaluate current and future soil concentrations are not yet available. Although there are no indications that crop production is currently inhibited by As, long-term risks are clearly present. Therefore, with concurrent assessments of the risks, management options to further prevent As accumulation in the topsoil should already have been explored. With regard to human health, data on As speciation in foods in combination with food consumption data are needed to assess dietary exposure, and these data should include spatial and seasonal variability. It is important to control confounding factors in assessing the risks. In a country where malnutrition

  10. Agricultural and Food Processing Applications of Pulsed Power and Plasma Technologies

    NASA Astrophysics Data System (ADS)

    Takaki, Koichi

    Agricultural and food processing applications of pulsed power and plasma technologies are described in this paper. Repetitively operated compact pulsed power generators with a moderate peak power are developed for the agricultural and the food processing applications. These applications are mainly based on biological effects and can be categorized as germination control of plants such as Basidiomycota and arabidopsis inactivation of bacteria in soil and liquid medium of hydroponics; extraction of juice from fruits and vegetables; decontamination of air and liquid, etc. Types of pulsed power that have biological effects are caused with gas discharges, water discharges, and electromagnetic fields. The discharges yield free radicals, UV radiation, intense electric field, and shock waves. Biologically based applications of pulsed power and plasma are performed by selecting the type that gives the target objects the adequate result from among these agents or byproducts. For instance, intense electric fields form pores on the cell membrane, which is called electroporation, or influence the nuclei. This paper mainly describes the application of the pulsed power for the germination control of Basidiomycota i.e. mushroom, inactivation of fungi in the soil and the liquid medium in hydroponics, and extraction of polyphenol from skins of grape.

  11. A seasonal agricultural drought forecast system for food-insecure regions of East Africa

    The increasing food and water demands of East Africa's growing population are stressing the region's inconsistent water resources and rain-fed agriculture. More accurate seasonal agricultural drought forecasts for this region can inform better water and agropastoral management decisions, support optimal allocation of the region's water resources, and mitigate socioeconomic losses incurred by droughts and floods. Here we describe the development and implementation of a seasonal agricultural drought forecast system for East Africa (EA) that provides decision support for the Famine Early Warning Systems Network's (FEWS NET) science team. We evaluate this forecast system for a region of equatorial EA (2° S-8° N, 36-46° E) for the March-April-May (MAM) growing season. This domain encompasses one of the most food-insecure, climatically variable, and socioeconomically vulnerable regions in EA, and potentially the world; this region has experienced famine as recently as 2011. To produce an "agricultural outlook", our forecast system simulates soil moisture (SM) scenarios using the Variable Infiltration Capacity (VIC) hydrologic model forced with climate scenarios describing the upcoming season. First, we forced the VIC model with high-quality atmospheric observations to produce baseline soil moisture (SM) estimates (here after referred as SM a posteriori estimates). These compared favorably (correlation = 0.75) with the water requirement satisfaction index (WRSI), an index that the FEWS NET uses to estimate crop yields. Next, we evaluated the SM forecasts generated by this system on 5 March and 5 April of each year between 1993 and 2012 by comparing them with the corresponding SM a posteriori estimates. We found that initializing SM forecasts with start-of-season (SOS) (5 March) SM conditions resulted in useful SM forecast skill (> 0.5 correlation) at 1-month and, in some cases, 3-month lead times. Similarly, when the forecast was initialized with midseason (i.e., 5

    Despite massive investments in food aid, agricultural extension, and seed/fertilizer subsidies, nearly 1 billion people in the developing world are food insecure and vulnerable to climate variability. Sub-Saharan Africa is most vulnerable, as approximately 25% of its people are undernourished (FAO/FAOSTAT 2013) and 96% of its cropland is rainfed (FAO 2002). The ability of subsistence farmers to respond to changes in water availability involves both inter-and intra-seasonal adaptation. Adaptive capacity diminishes over the season as decisions are made, resources are used, and the set of possible futures becomes restricted. Assessing the intra-seasonal adaptive capacity of smallholders requires integrating physical models of hydrological and agricultural dynamics with farmer decision-making at fine temporal (e.g. weekly) and spatial (e.g. crop field) scales. However, there is an intrinsic challenge to modeling the dynamics of these sociohydrologic systems, because important and uncharacterized spatial and temporal scale mismatches exist between the level at which the water resource is best understood and the level at which human dynamics are more predictable. For example, the skill of current process-based land surface models is primarily confined to short-term (daily to weekly), national- to regional-scale assessments, and reliable agricultural yield estimates and forecasts for small-scale farming systems remain elusive. In contrast, process-based social science modeling has focused on agent-based approaches that generate fine-scale (individual to community) dynamics over rather coarse time scales (yearly to decadal). A major obstacle to addressing this mismatch is the fundamental fact that the highest skill domain of one framework is essentially unpredictable in the other. We present a coupled sociohydrological observation framework designed to addressing this gap, and demonstrate its utility to understand relationships between climate variability, decision making

  13. Phosphorus Cycling in Montreal’s Food and Urban Agriculture Systems

    Cities are a key system in anthropogenic phosphorus (P) cycling because they concentrate both P demand and waste production. Urban agriculture (UA) has been proposed as a means to improve P management by recycling cities’ P-rich waste back into local food production. However, we have a limited understanding of the role UA currently plays in the P cycle of cities or its potential to recycle local P waste. Using existing data combined with surveys of local UA practitioners, we quantified the role of UA in the P cycle of Montreal, Canada to explore the potential for UA to recycle local P waste. We also used existing data to complete a substance flow analysis of P flows in the overall food system of Montreal. In 2012, Montreal imported 3.5 Gg of P in food, of which 2.63 Gg ultimately accumulated in landfills, 0.36 Gg were discharged to local waters, and only 0.09 Gg were recycled through composting. We found that UA is only a small sub-system in the overall P cycle of the city, contributing just 0.44% of the P consumed as food in the city. However, within the UA system, the rate of recycling is high: 73% of inputs applied to soil were from recycled sources. While a Quebec mandate to recycle 100% of all organic waste by 2020 might increase the role of UA in P recycling, the area of land in UA is too small to accommodate all P waste produced on the island. UA may, however, be a valuable pathway to improve urban P sustainability by acting as an activity that changes residents’ relationship to, and understanding of, the food system and increases their acceptance of composting.

  14. Recycling soil nitrate nitrogen by amending agricultural lands with oily food waste.

    PubMed

    Rashid, M T; Voroney, R P

    2003-01-01

    With current agricultural practices the amounts of fertilizer N applied are frequently more than the amounts removed by the crop. Excessive N application may result in short-term accumulation of nitrate nitrogen (NO3-N) in soil, which can easily be leached from the root zone and into the ground water. A management practice suggested for conserving accumulated NO3-N is the application of oily food waste (FOG; fat + oil + greases) to agricultural soils. A two-year field study (1995-1996 and 1996-1997) was conducted at Elora Research Center (43 degrees 38' N, 80 degrees W; 346 m above mean sea level), University of Guelph, Ontario, Canada to determine the effect of FOG application in fall and spring on soil NO3-N contents and apparent N immobilization-mineralization of soil N in the 0- to 60-cm soil layer. The experiment was planned under a randomized complete block design with four replications. An unamended control and a reference treatment [winter wheat (Triticum aestivum L.) cover crop] were included in the experiment to compare the effects of fall and spring treatment of oily food waste on soil NO3-N contents and apparent N immobilization-mineralization. Oily food waste application at 10 Mg ha(-1) in the fall decreased soil NO3-N by immobilization and conserved 47 to 56 kg NO3-N ha(-1), which would otherwise be subject to leaching. Nitrogen immobilized due to FOG application in the fall was subsequently remineralized by the time of fertilizer N sidedress, whereas no net mineralization was observed in spring-amended plots at the same time.

    The causes of many vexing challenges facing 21st-century society are at the nexus of systems involved in agriculture, health and wealth production, consumption, and distribution. Using food as a test bed, and on the basis of emerging roadmaps that set achievable objectives over a 1- to 3-year horizon, we introduce this special feature with convergence thinking and practice at its core. Specifically, we discuss academic papers structured around four themes: (1) evidence for a need for convergence and underlying mechanisms at the individual and societal levels; (2) strategy for mainstreaming convergence as a driver of business engagement and innovation; (3) convergence in policy and governance; (4) convergence in metrics and methods. Academic papers under each theme are accompanied by a roadmap paper reporting on the current status of concrete transformative convergence-building projects associated with that theme. We believe that the insights provided by these papers have the potential to enable all actors throughout society to singly and collectively work to build supply and demand for nutritious food, in both traditional and modern food systems, while placing the burdens of malnutrition and ill health on their core strategic agendas.

  17. Transformative optimisation of agricultural land use to meet future food demands.

    The human population is expected to reach ∼9 billion by 2050. The ensuing demands for water, food and energy would intensify land-use conflicts and exacerbate environmental impacts. Therefore we urgently need to reconcile our growing consumptive needs with environmental protection. Here, we explore the potential of a land-use optimisation strategy to increase global agricultural production on two major groups of crops: cereals and oilseeds. We implemented a spatially-explicit computer simulation model across 173 countries based on the following algorithm: on any cropland, always produce the most productive crop given all other crops currently being produced locally and the site-specific biophysical, economic and technological constraints to production. Globally, this strategy resulted in net increases in annual production of cereal and oilseed crops from 1.9 billion to 2.9 billion tons (46%), and from 427 million to 481 million tons (13%), respectively, without any change in total land area harvested for cereals or oilseeds. This thought experiment demonstrates that, in theory, more optimal use of existing farmlands could help meet future crop demands. In practice there might be cultural, social and institutional barriers that limit the full realisation of this theoretical potential. Nevertheless, these constraints have to be weighed against the consequences of not producing enough food, particularly in regions already facing food shortages.

    Malawi has spearheaded an unprecedented policy change in sub-Saharan Africa (SSA) since 2005 when it started a widespread agricultural inputs subsidy program (AISP) targeting small farmer maize production with mineral fertilizer and improved seeds. Since then, the mean N fertilizer load has increased significantly, from ~ 0 to a modest 35 kg N/ha or 7 times greater than SSA's average 5 kg N/ha average. During the tenure of AISP, Malawi has transitioned from a food aid recipient to an exporter. Maize yields each year of AISP are double the long-term average (0.8 tons/ha/yr, 1960-2005). In 2007, subsidy inputs combined with good rains led to of an unprecedented increase in national average yields of 2.7 tons/ha. National-scale assessments covering, agriculture, poverty, and environment such as this one are required to understand the trade-offs between development, climate and the environment. Environmentally, N2O emissions from fertilizer are a concern. First order estimates put emissions from AISP fertilizers at 2,600 Mg N2O/year (0.81 Tg CO2-e). While globally insignificant, these emissions may be equivalent to 16% of Malawi's annual fossil fuel and deforestation emissions. However, our partial nutrient budgets indicate that crop removal is still higher than N applied and therefore little loss of N to the environment is expected. Mineral fertilizers are a rapid first step to increase soil N after 40 years of serious depletion. Once restored, the soils will support robust agroforestry and other forms of organic inputs produced on-farm. Fertilizer use increases carbon sequestration on agricultural soils and reduces pressure to clear forests, which may partially compensate for the N2O emissions. We find evidence that AISP significantly increases food security and mitigates the impacts of drought on maize production. This is the first work linking the distribution of fertilizer subsidies to local crop yields using government records, remotely-sensed time series of

    An integrated System Dynamics Model for the Rosetta region, Egypt, assessing local water balance and agricultural yield to 2050, is presented. Fifty-seven simulations are analysed to better understand potential impacts on water and food security resulting from climate and social change and local/regional policy decisions related to the agricultural sector. Water limitation is a national issue: Egypt relies on the Nile for >95% of supply, and the flow of which is regulated by the Aswan High Dam. Egypt's share water of Aswan water is limited to 55 x 19 m3 yr-1. Any reduction in supply to the reservoir or increase in demand (e.g. from an expanding agricultural sector), has the potential to lead to a serious food and water supply situation. Results show current water resource over-exploitation. The remaining suite of 56 simulations, divided into seven scenarios, also mostly show resource overexploitation. Only under significant increases to Nile flow volumes was the trend reversed. Despite this, by threading together multiple local policies to reduce demand and improve/maintain supply, water resource exploitation can be mitigated while allowing for agricultural development. By changing cropping patterns, it is possible to improve yield and revenue, while using up to 21% less water in 2050 when compared with today. The results are useful in highlighting pathways to improving future water resource availability. Many policies should be considered in parallel, introducing redundancy into the policy framework. We do not suggest actual policy measures; this was beyond the scope of the work. This work highlights the utility of systems modelling of complex systems such as the water-food nexus, with the potential to extend the methodology to other studies and scales. In particular, the benefit of being able to easily modify and extend existing models in light of results from initial modelling efforts is cited. Analysis of initial results led to the hypothesis that by producing

    The next-generation sequencing technologies are able to produce millions of short sequence reads in a high-throughput, cost-effective fashion. The emergence of these technologies has not only facilitated genome sequencing but also started to change the landscape of life sciences. Here, I survey their major applications ranging from whole-genome sequencing and resequencing, single nucleotide polymorphism (SNP) and structural variation discovery, to mRNA and noncoding RNA profiling and protein-nucleic acid interaction assay. These case studies in structural, functional and comparative genomics, metagenomics, and epigenomics are providing a more complete picture of the genome structures and functions. In the near future, we will witness broad impacts of these next-generation sequencing technologies for solving the complex biological problems in food, nutrition and agriculture. In this article, recent patents based information is also included.

    This paper compares the theoretical specification of production and technical change across the partial equilibrium (PE) and computable general equilibrium (CGE) models of the global agricultural and food system included in the AgMIP model comparison study. The two modeling approaches have different theoretical underpinnings concerning the scope of economic activity they capture and how they represent technology and the behavior of supply and demand in markets. This paper focuses on their different specifications of technology and supply behavior, comparing their theoretical and empirical treatments. While the models differ widely in their specifications of technology, both within and between the PE and CGE classes of models, we find that the theoretical responsiveness of supply to changes in prices can be similar, depending on parameter choices that define the behavior of supply functions over the domain of applicability defined by the common scenarios used in the AgMIP comparisons. In particular, we compare the theoretical specification of supply in CGE models with neoclassical production functions and PE models that focus on land and crop yields in agriculture. In practice, however, comparability of results given parameter choices is an empirical question, and the models differ in their sensitivity to variations in specification. To illustrate the issues, sensitivity analysis is done with one global CGE model, MAGNET, to indicate how the results vary with different specification of technical change, and how they compare with the results from PE models.

  4. Affordability and Obesity: Issues in the Multifunctionality of Agricultural/Food Systems

    PubMed Central

    Sturm, Roland

    2009-01-01

    The conference discussed public goods and externalities created as by-products of the food system, including local development, obesity, air and water pollution, climate change, antibiotic resistance, and other public health issues. Multifunctionality is a framework that integrates these diverse issues and has been influential in international policy. This commentary focuses on arguably the most prominent public health issue at the moment: obesity. Though obesity could be considered another multifunctional dimension, its link to other conference topics is tenuous. Using obesity as an argument to promote local produce or achieve other multifunctional outcomes is very questionable. Framing obesity as an issue of poverty or food insecurity trivializes the continuing major problem of hunger worldwide. PMID:21113389

    In 1988, the late Prof. Rikimaru Hayashi had first proposed "Use of High Pressure in Food", introducing his views, i.e., "heat and pressure are independently capable of transforming the state of a substance, and such state transforming factors are only heat and pressure in nature." Sc. D. Masaru Nakahara stated in his note that he had been impressed by the unique starting point of Prof. Hayashi's idea. Prof. Hayashi had explored some good method for food processing without using heat, so he alternatively thought of high-pressure treatment (Hayashi R (1989) Use of high pressure to food processing and preservation. In: Hayashi R (ed) Use of high pressure in food. San-Ei Publishing Co, Kyoto, pp 1-30; Nakahara M (1990) Water and ions at high pressure: their fundamental properties relevant to the pressure treatment to food. In: Hayashi R (ed) Pressure-processed food--research and development. San-Ei Publishing Co, Kyoto, pp 3-21). Since the start-up of Japanese research group of high pressure in biological field (the present "Japanese Research Group of High Pressure Bioscience and Biotechnology (JHPBB)") and "International Association of High Pressure Bioscience and Biotechnology (IAHPBB)", we have continued to research into the industrial use of high-pressure treatment over a period of 25 years to realize our dream, that is, the same as Prof. Hayashi's dream. Although heat and pressure were found to be independent factors capable of transforming the state of a substance, use of heat has been overwhelmingly more frequent in food processing up to now. However, the pressure treatment has the advantages of instantaneous transmission, uniform distribution in vessels, and ability of inducing uniform change in quality. The high-pressure treatment does not cause cleavage of the covalent bond in the substance, thereby lessening the decomposition of nutrients, the generation of offensive smell, and the production of abnormal materials when compared with the heat application.

    Foreign bodies (FBs) in food are health hazards and quality issues for many food manufacturers and enforcement authorities. In this study, continuous wave (CW) terahertz (THz) imaging at 0.2 THz with an output power of 10 mW was compared with X-ray imaging as techniques for inspection of food for FBs. High-density FBs, i.e., aluminum and granite pieces of various sizes, were embedded in a powdered instant noodle product and detected using THz and X-ray imaging. All aluminum and granite pieces (regular hexahedrons with an edge length of 1 to 5 mm) were visualized by both CW THz and X-ray imaging. THz imaging also detected maggots (length = 8 to 22 mm) and crickets (length = 35 and 50 mm), which were embedded in samples as low density FBs. However, not all sizes of maggot pieces embedded in powdered instant noodle were detected with X-ray imaging, although larger crickets (length = 50 mm and thickness = 10 mm) were detected. These results suggest that CW THz imaging has potential for detecting both high-density and low-density FBs embedded in food.

  11. Seawater/Saline Agriculture for Energy, Warming, Water, Rainfall, Land, Food and Minerals

    NASA Technical Reports Server (NTRS)

    Bushnell, Dennis

    2006-01-01

    The combination of the incipient demise of cheap oil and increasing evidence of Global Warming due to anthropogenic fossil carbon release has reinvigorated the need for and efforts on Renewable energy sources, especially for transportation applications. Biomass/Bio-diesel appears to have many benefits compared to Hydrogen, the only other major renewable transportation fuel candidate. Biomass Production is currently limited by available arable land and fresh water. Halophyte Plants and seawater irrigation proffer a wholly new biomass production mantra using wastelands and very plentiful seawater. Such an approach addresses many-to-most of the major emerging Societal Problems including Land, Water, Food, Warming and Energy. For many reasons, including seawater agriculture, portions of the Sahara appear to be viable candidates for future Biomass Production. The apparent nonlinearity between vegetation cover and atmospheric conditions over North Africa necessitates serious coupled boundary layer Meteorology and Global Circulation Modeling to ensure that this form of Terra Forming is Favorable and to avoid adverse Unintended Consequences.

  12. Bacterial-Fungal Interactions: Hyphens between Agricultural, Clinical, Environmental, and Food Microbiologists

    Frey-Klett, P.; Burlinson, P.; Deveau, A.; Barret, M.; Tarkka, M.; Sarniguet, A.

    2011-01-01

    Summary: Bacteria and fungi can form a range of physical associations that depend on various modes of molecular communication for their development and functioning. These bacterial-fungal interactions often result in changes to the pathogenicity or the nutritional influence of one or both partners toward plants or animals (including humans). They can also result in unique contributions to biogeochemical cycles and biotechnological processes. Thus, the interactions between bacteria and fungi are of central importance to numerous biological questions in agriculture, forestry, environmental science, food production, and medicine. Here we present a structured review of bacterial-fungal interactions, illustrated by examples sourced from many diverse scientific fields. We consider the general and specific properties of these interactions, providing a global perspective across this emerging multidisciplinary research area. We show that in many cases, parallels can be drawn between different scenarios in which bacterial-fungal interactions are important. Finally, we discuss how new avenues of investigation may enhance our ability to combat, manipulate, or exploit bacterial-fungal complexes for the economic and practical benefit of humanity as well as reshape our current understanding of bacterial and fungal ecology.

  13. Application of food industry waste to agricultural soils mitigates green house gas emissions.

    PubMed

    Rashid, M T; Voroney, R P; Khalid, M

    2010-01-01

    Application of organic waste materials such as food processing and serving industry cooking oil waste (OFW) can recycle soil nitrate nitrogen (NO(3)-N), which is otherwise prone to leaching after the harvest of crop. Nitrogen (N) recycling will not only reduce the amount of N fertilizer application for corn crop production but is also expected to mitigate green house gas (GHG) emissions by saving energy to be used for the production of the same amount of industrial fertilizer N required for the growth of corn crop. Application of OFW at 10Mg solid ha(-1)y(-1) conserved 68 kg N ha(-1)y(-1) which ultimately saved 134 L diesel ha(-1)y(-1), which would otherwise be used for the production of fertilizer N as urea. Average fossil energy substitution value (FESV) of N conserved/recycled was calculated to be 93 US$ ha(-1)y(-1), which is about 13 million US$y(-1). Potential amount of GHG mitigation through the application of OFW to agricultural soils in Canada is estimated to be 57 Gg CO(2)Eq y(-1).

  14. Concentrations and speciation of arsenic in New England seaweed species harvested for food and agriculture.

    PubMed

    Taylor, Vivien F; Jackson, Brian P

    2016-11-01

    A survey of arsenic (As) concentrations and speciation was conducted on 10 species of seaweed from commercial harvesters and from collection at two sites in New England. Concentrations of As ranged from 4 to 106 mg/kg, mostly in the form of arsenosugars, with the distribution of arsenosugar analogs varying between taxa. In brown algae, As levels were correlated with phosphate concentrations, and arsenosugar speciation reflected differences in sulfur and phosphate concentrations between taxa. Several samples of the brown algae species Laminaria digitata contained significant levels of inorganic As (2.8-20 mg/kg), the most toxic form of As. A weak acid extraction with microwave heating was compared with a weaker methanol: water extraction method, and found to give slightly higher extraction efficiency with comparable relative concentrations of inorganic As, supporting the use of this faster and simpler extraction method for monitoring. Seaweed is a niche dietary item in the U.S. but its popularity is increasing; it is also used in agriculture and livestock farming which provide potential indirect routes for human exposure. The presence of occasional high concentrations of iAs, as well as the lack of toxicity studies on organic As species, suggest that monitoring of these high As foods is warranted. PMID:27517127

  15. New MOEMS based systems appropriate for spectroscopic investigations on agricultural growth and perishable food conditions

    NASA Astrophysics Data System (ADS)

    Further optimization of the agricultural growth process and quality control of perishable food which can be fruits and vegetables as well as every kind of meat or milk product requires new approaches for the sensitive front end. One possibility is reflectance or fluorescence spectroscopy in a wide wavelength range. By now broad usage is hindered by costs, size and performance of existing systems. MOEMS scanning gratings for spectrometers and translational mirrors for Fourier Transform spectroscopy enable small robust systems working in a range from 200nm to 5μm. Both types use digital signal processors (DSPs) capable to compute the spectra and execute complex evaluation and decision algorithms. The MOEMS chips are realized by anisotropic etching of a silicon on insulator (SOI) substrate. First the backside silicon and buried oxide is removed by a wet process then the front side structure is realized by dry etching. Depending on the bearing springs a silicon plate up to 3 x 3 mm2 wide and typically 30μm thick can be driven resonantly to rotational or translational movement. Combined with additional optical components and appropriate detectors handheld Czerny-Turner or Fourier Transform spectrometers have been realized and tested. Results of first measurements of reflection spectroscopy on model substances have been performed with both system types in the NIR range. Measurements on real objects like tomatoes or apples are intended for a wider wavelength range. Future systems may contain displays and light sources as well as data storage cards or additional interfaces.

  16. Numerical study of light propagation in agricultural products for non-destructive assessment of food quality

    NASA Astrophysics Data System (ADS)

    Hattori, Kiyohito; Fujii, Hiroyuki; Tatekura, Yuki; Kobayashi, Kazumichi; Watanabe, Masao

    2015-12-01

    An accurate determination of optical properties of agricultural products is crucial for non-destructive assessment of food quality. For the determination, light intensity is measured at the surface of the product; then, inverse analysis is employed based on a light propagation model such as the radiative transfer equation (RTE). The inverse analysis requires high computational loads because the light intensity is numerically calculated using the model every time the optical properties are changed. For the calculation, we propose an efficient technique by combining a numerical solution with an analytical solution of the RTE, and investigate the validity of the technique in a two-dimensional homogeneous circular medium which is regarded as a light propagation model with optical properties of kiwifruit. The proposed technique can provide accurate results of the light intensity in change of the optical properties, and the accuracy is less dependent on the boundary conditions and source-detector angles. In addition, the technique can reduce computation time compared with that for numerical calculation of the RTE. These results indicate usefulness of the proposed technique for the inverse analysis.

Seaweed is a niche dietary item in the U.S. but its popularity is increasing; it is also used in agriculture and livestock farming which provide potential indirect routes for human exposure. The presence of occasional high concentrations of iAs, as well as the lack of toxicity studies on organic As species, suggest that monitoring of these high As foods is warranted.

    In this commentary, we use examples from West Africa to highlight how the liberalization of global agricultural trade exacerbates population health inequalities by threatening the livelihoods and food security of communities in low-income settings. We highlight the exploitative nature of trade agreements with West African countries demonstrating how these agreements disincentivize local agricultural investment and take jobs away from small-scale farmers. Further, we link agricultural trade liberalization to increased food insecurity, malnutrition, and exposure to environmental contaminants. Finally, we propose a paradigm shift that advocates for food sovereignty and the right to food.

    Human population growth in the developing world drives land-use changes, impacting food security. In India, the dramatic change in demographic dynamics over the past century has reduced traditional agricultural land-use through increasing commercialization. Here, we analyze the magnitude and implications for the farming system by the introduction of cash-cropping, replacing the traditional slash and burn rotations (jhum), of the tribal people on the Meghalaya Plateau, northeast India, by means of agricultural census data and field surveys conducted in seven villages. Land-use change has brought major alterations in hill agricultural practices, enhanced cash-cropping, promoted mono-cropping, changed food consumption patterns, underpinned the emergence of a new food system, and exposed farmers and consumers to the precariousness of the market, all of which have both long- and short-term food security implications. We found dietary diversity to be higher under jhum compared to any of the cash-crop systems, and higher under traditional cash-cropping than under modern cash-cropping. PMID:26254789

    As an inspection technology, x-rays have been used in food product inspection for a number of years. Despite this, in contrast with the use of image processing techniques in medical applications of x-rays, food inspection systems have remained relatively rudimentary. SOme of our earlier work in this area has been stimulate by specific x-ray inspection tasks, where we have been required to locate contaminants in batches of particular packaged products. We have developed techniques for contaminant detection in both canned and bagged products. This paper gives an overview of work undertaken by Industrial Research Limited on the development of automated machine vision techniques for the inspection of food products for contaminants. Our recent work has concentrated on the development of more generic techniques for detecting contaminants in a wide range of continuously produced products, with no requirement for product singulation. A particular emphasis in our work has been the real-time detection of contaminants appearing indistinctly in x-ray images in the presence of noise and major product variability.

    Although rhetoric abounds in the agricultural education literature regarding the public's dearth of agri-food system literacy, problems arise when establishing educational interventions to help ameliorate illiteracy. Researchers do not fully know what individuals understand about the complex agri-food system. Hence, educational programs and curricula may focus on areas where students already possess well developed and scientifically accurate schemata, while ignoring other areas where incompatible or naive understandings persist. Democratic decisions about complex societal and environmental issues, such as trade-offs of our industrial agri-food system, require individuals to possess understandings of complex interrelationships. This exploratory qualitative study determines what two groups---elementary students and prospective elementary school teachers---understand about selected concepts foundational to agri-food system literacy. To ground the study in current national education curricular standards, a synthesis of both agricultural and science education benchmarks was developed. This helped structure interviews with the study's informants: nine elementary students and nine prospective elementary teachers. Analysis of discourse was based upon a conceptual change methodology. Findings showed that informant background and non-school experiences were linked to agri-food system literacy, while formal, in-school learning was not. For elementary students, high socio-economic status, gardening and not living in urban areas were correlates with literacy; the prospective teacher group exhibited similar trends. Informants understood that food came from farms where plants and animals were raised. For the majority, however, farms were described as large gardens. Additionally, informants lacked a clear understanding of the roles soil and fertilizers play in crop production. Further, few spoke of weeds as competitors with crops for growth requirements. Informants understood that

    A request from the Norwegian Ministry of Agriculture to the Food and Agriculture Organization of the United Nations (FAO) in 1973 led to a research project funded by the Government of Norway to examine the declining use of mother's milk in developing countries. Two consultants were appointed to compile information on the subject, to develop a theoretical model to illustrate the economic value of breastfeeding, and to study the situation in two developing countries, Ghana and the Ivory Coast. Lack of data was a problem in both countries, but estimates could be made, and some of the conclusions reached are the following. Breastfeeding is still the norm in both countries, yet if it were to increase in the Ivory Coast so that every infant were breastfed for two years the savings in national goods cost could amount to US$ 16 to 28 million annually. If it declined to the level of Paris in 1955 (chosen for comparison) the annual national cost would be between US$ 33 and 55 million. At the individual level, by breastfeeding rather than artificially feeding an infant for two years the average family in either country would save between US$ 600 and 730 in the cost of goods and time, plus any savings that might result from the avoidance of disease or malnutrition caused by artificial feeding. In Ghana, changes in the infant-feeding pattern due to rural-to-urban migration would cause only a 20-percent increase in formula imports, while import increases would be more than five times as great as this if the present severe restrictions were relaxed so that formula replaced only one percent of the potential national breast-milk production. A change to artificial feeding could possibly result in considerable population growth because of loss of the contraceptive effect (through lactation amenorrhoea) of breastfeeding. In-depth studies of the economics of breastfeeding present great difficulties and would probably not justify their high cost. The report suggests that studies be

    Bioenergies are promoted across the globe as the answer for global warming and the chance to reduce dependency from fossil energy sources. Despite the fact that renewable energy sources offer the opportunity to reduce CO2 emission and present a chance to increase agricultural incomes, they also come along with some drawbacks that have been mostly neglected in the current discussion. This paper seeks to build a basis for discussing the impacts of the growing subsidization of bioenergy and the resulting usage competition of agricultural raw materials between foods and energy. To assess the usage competition and the subsidization of bioenergy, this article employs a welfare economics perspective associated with an emphasize on the construct of externalities. This will help to foster the discussion on the further subsidization of bioenergy, where funding for R&D on new ways of using non-food raw materials ought to play a significant role.

    In the regions that experience substantial climatic risks, considerable traditional expertise exists that is underutilized and that could be valuable as a starting point to build more effective strategies for adapting to climate change and ensure food availability. Some of these are agronomic strategies for soil conservation targeting erosion avoidance as a form to ensure soil fertility and thus, crop production and food availability. Following an extensive literature review in the Indogangetic Plans, we have identified many different practices derived from local traditional knowledge that can be classified as i) Reshaping the landscape (terracing, bunding, efficient distribution of land uses); ii) Stream diversion to reduce flood impact (channels along the edges of the fields, embankments, dams, network of ponds, outlets, walls and fencing); and iii) Others (agroforesty, use of specific trees as indicators of soil erosion, crop-fallow rotation, preservation of patches of forests, reforestation, collective management of forests). These endogenous-based practices have a great potential for adaptation since they are more easily adopted by communities, they require of minimum or not external expertise and aid, and usually, are cheaper than other strategies. A combination of local knowledge with other scientific knowledge may be the most effective way to face climate change.

These global models can then relay important global-level information that drive regional decision-making and outcomes throughout an interconnected agricultural system. AgMIP's community of nearly 800 climate, crop, livestock, economics, and IT experts has improved the state-of-the-art through model intercomparisons, validation exercises, regional integrated assessments, and the launch of AgMIP programs on all six arable continents. AgMIP is now launching Coordinated Global and Regional Assessments (CGRA) of climate change impacts on agriculture and food security to link global and regional crop and economic models using a protocol-based framework. The CGRA protocols are being developed to utilize historical observations, climate projections, and RCPs/SSPs from CMIP5 (and potentially CMIP6), and will examine stakeholder-driven agricultural development and adaptation scenarios to provide cutting-edge assessments of climate change's impact on agriculture and food security. These protocols will build on the foundation of established protocols from AgMIP's 30+ activities, and will emphasize the use of multiple models, scenarios, and scales to enable an accurate assessment of related uncertainties. The CGRA is also designed to provide the outputs necessary to feed into integrated assessment models (IAMs), nutrition and food security assessments, nitrogen and carbon cycle models, and additional impact-sector assessments (e.g., water resources, land-use, biomes, urban areas). This presentation will describe the current status of CGRA planning and initial prototype experiments to demonstrate key aspects of the protocols before wider implementation ahead of the IPCC Sixth Assessment

    In-season monitoring of crop conditions provides critical information for agricultural policy and decision making and most importantly for food security planning and management. Nationwide agricultural monitoring in countries dominated by smallholder farming systems, generally relies on extensive networks of field data collectors. In Tanzania, extension agents make up this network and report on conditions across the country, approaching a "near-census". Data is collected on paper which is resource and time intensive, as well as prone to errors. Data quality is ambiguous and there is a general lack of clear and functional feedback loops between farmers, extension agents, analysts and decision makers. Moreover, the data are not spatially explicit, limiting the usefulness for analysis and quality of policy outcomes. Despite significant advances in remote sensing and information communication technologies (ICT) for monitoring agriculture, the full potential of these new tools is yet to be realized in Tanzania. Their use is constrained by the lack of resources, skills and infrastructure to access and process these data. The use of ICT technologies for data collection, processing and analysis is equally limited. The AgriSense-STARS project is developing and testing a system for national-scale in-season monitoring of smallholder agriculture using a combination of three main tools, 1) GLAM-East Africa, an automated MODIS satellite image processing system, 2) field data collection using GeoODK and unmanned aerial vehicles (UAVs), and 3) the Tanzania Crop Monitor, a collaborative online portal for data management and reporting. These tools are developed and applied in Tanzania through the National Food Security Division of the Ministry of Agriculture, Food Security and Cooperatives (MAFC) within a statistically representative sampling framework (area frame) that ensures data quality, representability and resource efficiency.

    In modern agriculture, the interplay between complex physical, agricultural, and socioeconomic water use drivers must be fully understood to successfully manage water supplies on extended timescales. This is particularly evident across large portions of the High Plains Aquifer where groundwater levels have declined at unsustainable rates despite improvements in both the efficiency of water use and water productivity in agricultural practices. Improved technology and land use practices have not mitigated groundwater level declines, thus water management strategies must adapt accordingly or risk further resource loss. In this study, we analyze the water-energy-food nexus over the High Plains Aquifer as a framework to isolate the major drivers that have shaped the history, and will direct the future, of water use in modern agriculture. Based on this analysis, we conclude that future water management strategies can benefit from: (1) prioritizing farmer profit to encourage decision-making that aligns with strategic objectives, (2) management of water as both an input into the water-energy-food nexus and a key incentive for farmers, (3) adaptive frameworks that allow for short-term objectives within long-term goals, (4) innovative strategies that fit within restrictive political frameworks, (5) reduced production risks to aid farmer decision-making, and (6) increasing the political desire to conserve valuable water resources. This research sets the foundation to address water management as a function of complex decision-making trends linked to the water-energy-food nexus. Water management strategy recommendations are made based on the objective of balancing farmer profit and conserving water resources to ensure future agricultural production. PMID:27344509

    A health impact assessment (HIA) to consider the potential effects of European Union accession on agriculture and food policies in Slovenia has been undertaken as a joint project between the Slovenian Ministry of Health and the WHO European Region. The HIA project in Slovenia was conducted as a pilot project to develop the methods of HIA in this policy sector. The implications of the European Union Agricultural Policy to health are discussed. HIA methods have been used to assess some of the potential effects in Slovenia of accession to the European Union. This paper outlines some of the early findings and lessons to be learnt from the Slovenian HIA experience in order that other countries may adopt the approach to improve health considerations in agriculture and other intersectoral policymaking.

    This paper quantifies the eco-hydrological challenge up until 2050 of producing food in balance with goods and services generated by water-dependent ecosystems in nature. Particular focus is given to the savannah zone, covering 40% of the land area in the world, where water scarcity constitutes a serious constraint to sustainable development. The analysis indicates an urgent need for a new green revolution, which focuses on upgrading rain-fed agriculture. Water requirements to produce adequate diets for humans are shown to be relatively generic irrespective of hydro-climate, amounting to a global average of 1,300 m(3) cap(-1) yr(-1). Present food production requires an estimated 6,800 km(3) yr(-1) of consumptive green water (5,000 km(3) yr(-1) in rain-fed agriculture and 1,800 km(3) yr(-1) from irrigated crops). Without considering water productivity gains, an additional 5,800 km(3) yr(-1) of water is needed to feed a growing population in 2,050 and eradicate malnutrition. It is shown that the bulk of this water will be used in rain-fed agriculture. A dynamic analysis of water productivity and management options indicates that large 'crop per drop' improvements can be achieved at the farm level. Vapour shift in favour of productive green water flow as crop transpiration could result in relative water savings of 500 km(3) yr(-1) in semi-arid rain-fed agriculture. PMID:14728794

    Agricultural pesticides are regularly found in surface waters at concentration levels that raise ecotoxicological concerns. Due to large fluctuations in concentration over time and the potentially high number of pesticides in agricultural watersheds, it is difficult to obtain a comprehensive overview of the actual pollution level. This collaborative project between research and Swiss federal and cantonal authorities aimed for a comprehensive analysis of pesticide pollution in five small agricultural streams to address this knowledge gap. The five rivers are located in catchments (1.5 to 9 km2) with intensive agriculture covering a wide range of crops, such as grains, vegetables, vineyards and orchards. Urban activities and influences are low. Twelve-hour composite samples were collected continuously from March until the end of August with automatic sampling devices, resulting in 360 samples per site. Using precipitation and water level data, we differentiated between discharge events and low-flow periods. Samples taken during dry weather were pooled for the analysis. This procedure resulted in a complete concentration profile over the entire monitoring period covered by 60 samples per site. The analysis, using liquid chromatography coupled to high resolution mass spectrometry (Orbitrap technology), involved a target screening of 248 pesticides including fungicides, herbicides, insecticides, as well as important transformation products. Data on the total number and distribution of pesticides, their detection frequency, crop specific applications and concentration time profiles will be presented. Preliminary results indicate substantial pesticide exposure since at least 20 different compounds were detected in all samples. One sample even contained a mixture of 80 pesticides. The majority of concentrations were in the low ng/L range but concentrations of a few compounds were very high (several micrograms/L) during discharge events as well as during low flow conditions

    In this paper, for a suite of 17 elements, we examine the temporal relationships between heavy-metal concentrations in water and food crops, and between different elements, at Chunga, Zambia, August 2004 to July 2005. In many locations in the developing world, the water source used for urban agriculture is often wastewater from industrial sources, and is potentially contaminated with heavy metals. In Zambia, the location of this study, the wastewater source for irrigation use in some urban areas has been called 'a sink for sewage, mining and industrial effluents' all of which potentially contain heavy metals. We present field research results examining relationships between heavy-metal concentrations in both the water and the foodcrops from an urban agriculture location in northwest Lusaka (Chunga), the capital of Zambia. Monthly monitoring of water and food crops irrigated by the water was carried out at the study site, August 2004 to July 2005, for n = 39 water samples and n = 17 food crop samples. Heavy-metal concentrations were examined for Al, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Cd, Ba, Hg, Tl, Pb, U (17 elements) using ICP-MS. We find that both water and food-crop samples have peak concentrations for many elements in the wet season (October to February). When examining temporal relationships, we find some positive and negative statistically significant correlations between elements for both [water]:[food crop] and [food crop]:[food crop]. For the concentrations of [water]:[food crop] we find particularly strong positive correlations for V:Se and (V, Cr, Co, Zn, Cd, Hg, Pb, U):Tl; strong negative correlations are observed for V:Zn, Ni:Cu, Cd:Cu. For [food crop]:[food crop] particularly strong positive relationships are observed for Al:V, Al:Cr, Cr:V, and Cd:U. Theoretically, concentrations of heavy-metals in plant samples normally should reflect the heavy-metal contamination in the water used to irrigate the plants throughout the growth cycle (typically six

    Tritium concentrations were measured in a large number of environmental and biological samples collected during 2002 at two dairy farms and a hobby farm near Pickering Nuclear Generating Station in Ontario, Canada. The data cover most compartments of the terrestrial food chain in an agricultural setting and include detailed information on the diets of the local farm animals. Ratios of plant OBT concentration to air moisture HTO varied between 0.12 and 0.56, and were generally higher for the forage crops collected at the dairy farms than for the garden vegetables sampled at the hobby farm. Animal OBT to air HTO ratios were more uniform, ranging from 0.18 to 0.45, and were generally higher for the milk and beef samples from the dairy farms than for the chicken products from the hobby farm. The observed OBT concentrations in plants and animals were compared with predictions of IMPACT, the model used by the Canadian nuclear industry to calculate annual average doses due to routine releases. The model performed well on average for the animal endpoints but overestimated concentrations in plants by a factor of 2.

    The direct chemical conversion of cocoa butter triglycerides, a material available as a postmanufacture waste stream from the food industry, to 1-decene by way of ethenolysis is reported. The conversion of the raw waste material was made possible by use of 1 mol % of the [RuCl2(iBu-phoban)2(3-phenylindenyl)] catalyst. The process has been investigated in both batch and flow conditions, where the latter approach employs a Teflon AF-2400 tube-in-tube gas–liquid membrane contactor to deliver ethylene to the reaction system. These preliminary studies culminate in a continuous processing system, which maintained a constant output over a 150 min period tested. PMID:26322250

    A continuous mixed immobilized sludge reactor (CMISR) using activated carbon as support carrier for dark fermentative hydrogen production from enzymatic hydrolyzed food waste was developed. The effects of immobilized sludge packing ratio (10-20%, v/v) and substrate loading rate (OLR) (8-40kg/m(3)/d) on biohydrogen production were examined, respectively. The hydrogen production rates (HPRs) with packing ratio of 15% were significantly higher than the results obtained from packing ratio of 10% and 20%. The best HPR of 353.9ml/h/L was obtained at the condition of packing ratio=15% and OLR=40kg/m(3)/d. The Minitab was used to elicit the effects of OLR and packing ratio on HPR (Y) which could be expressed as Y=5.31 OLR+296 packing ratio+40.3 (p=0.003). However, the highest hydrogen yield (85.6ml/g food waste) was happened at OLR of 16kg/m(3)/d because of H2 partial pressure and oxidization/reduction of NADH.

    The number of people which the world must feed is expected to increase by another 3 billion people by 2100. When coupled with significant nutritional improvements for the 2.1 billion people currently living on less than $2/day, this translates into a very substantial rise in the demand for agricultural production. At the same time, the growing use of biomass for energy generation has introduced an important new source of industrial demand in agricultural markets. To compound matters, water, a key input into agricultural production, is rapidly diminishing in availability in large parts of the world and many soils are degrading. In addition, agriculture and forestry are increasingly envisioned as key sectors for climate change mitigation policy. Any serious attempt to reduce land-based emissions will involve changes in the way farming is conducted, as well as placing limits on the expansion of farming - particularly in the tropics, where most of the agricultural land conversion has come at the expense of forests, either directly, or indirectly via a cascading of land use requirements with crops moving into pasture and pasture into forest. Finally, agriculture and forestry are likely to be the economic sectors whose productivity is most sharply affected by climate change. In light of these challenges facing the global farm and food system, this paper will review the main sources of supply and demand for the world's cropland, and then provide a quantitative assessment of the impact of these forces on global land use over the coming century. The model incorporates forward looking behavior and examines competition between land used for ecosystem services, forestry, food and fuel.

    Since 1980, the number of undernourished people in eastern and southern Africa has more than doubled. Rural development stalled and rural poverty expanded during the 1990s. Population growth remains very high, and declining per-capita agricultural capacity retards progress toward Millennium Development goals. Analyses of in situ station data and satellite observations of precipitation have identified another problematic trend: main growing-season rainfall receipts have diminished by ???15% in food-insecure countries clustered along the western rim of the Indian Ocean. Occurring during the main growing seasons in poor countries dependent on rain-fed agriculture, these declines are societally dangerous. Will they persist or intensify? Tracing moisture deficits upstream to an anthropogenically warming Indian Ocean leads us to conclude that further rainfall declines are likely. We present analyses suggesting that warming in the central Indian Ocean disrupts onshore moisture transports, reducing continental rainfall. Thus, late 20th-century anthropogenic Indian Ocean warming has probably already produced societally dangerous climate change by creating drought and social disruption in some of the world's most fragile food economies. We quantify the potential impacts of the observed precipitation and agricultural capacity trends by modeling 'millions of undernourished people' as a function of rainfall, population, cultivated area, seed, and fertilizer use. Persistence of current tendencies may result in a 50% increase in undernourished people by 2030. On the other hand, modest increases in per-capita agricultural productivity could more than offset the observed precipitation declines. Investing in agricultural development can help mitigate climate change while decreasing rural poverty and vulnerability. ?? 2008 by The National Academy of Sciences of the USA.

    Drought monitoring and planning requires spatially and temporally continuous information and its impacts on production and on society can easily be quantified when long-term (both crop production and climate) information is available. Such historical information is scanty and at best qualitative for Karamoja in Northeastern Uganda, a region considered to be most vulnerable to drought. To demonstrate the capabilities of currently available satellite data in filling this data gap in smallholder agricultural regions; this study first characterized agricultural drought at multiple temporal and spatial scales using Normalized Difference Vegetation Index (NDVI) data (1999-2011) and monthly rainfall data (1960-2011). Correlation analyses of the NDVI based drought indicators, Standardized Precipitation Index (SPI) and a global product of Palmer Drought Severity Index (PDSI). Spatial information is derived for the 1999-2000 period using MODIS 250m resolution data. The 12 month SPI (SPI-12) had the highest correlation with the MODIS NDVI record from (1999-2011) derived indices reaffirming the cumulative effect of rainfall on vegetation during the growing season and the utility of NDVI as an indicator of drought. Time-series plots were generated, the droughts were ranked and spatial maps derived for the most severe droughts between 2000- 2011. Temporal drought information is correlated with proxy indicators such as food aid supplies, available historical production data, market prices from within and in neighbouring regions and with to primary data collected through interviews with farmers in Moroto district. This study demonstrates that operationalizing drought monitoring can be realized with remote sensing and further affirms the importance of drought and agriculture monitoring for food security.

    Measuring the discharge of diffuse pollution from agricultural watersheds presents unique challenges. Flows in agricultural watersheds, particularly in Mediterranean climates, can be predominately irrigation runoff and exhibit large diurnal fluctuation in both volume and concentration. Flow and pollutant concentrations in these smaller watersheds dominated by human activity do not conform to a normal distribution and it is not clear if parametric methods are appropriate or accurate for load calculations. The objective of this study was to compare the accuracy of five load estimation methods to calculate pollutant loads from agricultural watersheds. Calculation of loads using results from discrete (grab) samples was compared with the true-load computed using in situ continuous monitoring measurements. A new method is introduced that uses a non-parametric measure of central tendency (the median) to calculate loads (median-load). The median-load method was compared to more commonly used parametric estimation methods which rely on using the mean as a measure of central tendency (mean-load and daily-load), a method that utilizes the total flow volume (volume-load), and a method that uses measure of flow at the time of sampling (instantaneous-load). Using measurements from ten watersheds in the San Joaquin Valley of California, the average percent error compared to the true-load for total dissolved solids (TDS) was 7.3% for the median-load, 6.9% for the mean-load, 6.9% for the volume-load, 16.9% for the instantaneous-load, and 18.7% for the daily-load methods of calculation. The results of this study show that parametric methods are surprisingly accurate, even for data that have starkly non-normal distributions and are highly skewed.

    This study was intended to characterize the perceived risks of urban agriculture by residents of four low-income neighborhoods in which the potential exists for further urban agriculture development and to provide data to support whether any chemical hazards and foodborne pathogens as potential food safety hazards were present. Sixty-seven residents participated in focus groups related to environmental health, food security, and urban gardening. In addition, soils from six locations were tested. Residents expressed interest in the development of urban gardens to improve access to healthy, fresh produce, but they had concerns about soil quality. Soils were contaminated with lead (Pb), zinc, cadmium (Cd), and copper, but not arsenic or chromium. Results from our study suggest paint was the main source of soil contamination. Detectable polyaromatic hydrocarbon (PAH) levels in urban soils were well below levels of concern. These urban soils will require further management to reduce Pb and possibly Cd bioavailability to decrease the potential for uptake into food crops. Although the number of locations in this study is limited, results suggest lower levels of soil contaminants at well-established gardens. Soil tillage associated with long-term gardening could have diluted the soil metal contaminants by mixing the contaminants with clean soil. Also, lower PAH levels in long-term gardening could be due to enhanced microbial activity and PAH degradation, dilution, or both due to mixing, similar to metals. No foodborne pathogen targets were detected by PCR from any of the soils. Residents expressed the need for clearness regarding soil quality and gardening practices in their neighborhoods to consume food grown in these urban areas. Results from this study suggest long-term gardening has the potential to reduce soil contaminants and their potential threat to food quality and human health and to improve access to fresh produce in low-income urban communities.

    Effective treatment and reuse of the massive quantities of agricultural and food wastes generated daily has the potential to improve the sustainability of food production systems. Anaerobic digestion (AD) is used throughout the world as a waste treatment process to convert organic waste into two main products: biogas and nutrient-rich digestate, called AD effluent. Biogas can be used as a source of renewable energy or transportation fuels, while AD effluent is traditionally applied to land as a soil amendment. However, there are economic and environmental concerns that limit widespread land application, which may lead to underutilization of AD for the treatment of agricultural and food wastes. To combat these constraints, existing and novel methods have emerged to treat or reuse AD effluent. The objective of this review is to analyze several emerging methods used for efficient treatment and reuse of AD effluent. Overall, the application of emerging technologies is limited by AD effluent composition, especially the total solid content. Some technologies, such as composting, use the solid fraction of AD effluent, while most other technologies, such as algae culture and struvite crystallization, use the liquid fraction. Therefore, dewatering of AD effluent, reuse of the liquid and solid fractions, and land application could all be combined to sustainably manage the large quantities of AD effluent produced. Issues such as pathogen regrowth and prevalence of emerging organic micro-pollutants are also discussed.

    During the Cold War, the super powers advanced nuclear literacy and access to nuclear resources and technology to a first-class power factor. Both national governments and international organizations developed nuclear programs in a variety of areas and promoted the development of nuclear applications in new environments. Research into the use of isotopes and radiation in agriculture, food production, and storage gained major importance as governments tried to promote the possibility of a peaceful use of atomic energy. This study is situated in divided Germany as the intersection of the competing socio-political systems and focuses on the period of the late 1940s and 1950s. It is argued that political interests and international power relations decisively shaped the development of "nuclear agriculture". The aim is to explore whether and how politicians in both parts of the divided country fostered the new field and exerted authority over the scientists. Finally, it examines the ways in which researchers adapted to the altered political conditions and expectations within the two political structures, by now fundamentally different. PMID:26775431

    Impacts of climate change have become obvious in agriculture and food production in Japan these days, and researches to adapt to their risks have been conducted as a key effort to cope with the climate change. Numerous scientific findings on climate change impacts have been presented so far; however, prospective risks to be adapted to and their management in the context of individual on-site situations have not been investigated in detail. The structure of climate change risks and their management vary depending on geographical and social features in the regions where the adaptation options should be applied; therefore, a practical adaptation strategy should consider actual on-site situations. This study intended to clarify climate change risks to be adapted to in the Japanese agricultural sector, and factors to be considered in adaptation options, for encouragement of decision-making on adaptation implementation in the field. Semi-structured individual interviews have been conducted with 9 multidisciplinary experts engaging in climate change impacts research in agricultural production, economics, engineering, policy, and so on. Based on the results of the interviews, and the latest literatures available for risk assessment and adaptation, an expert mental model including their perceptions which cover the process from climate change impacts assessment to adaptation has been developed. The prospective risks, adaptation options, and issues to be examined to progress the development of practical and effective adaptation options and to support individual or social decision-making, have been shown on the developed expert mental model. It is the basic information for developing social communication and stakeholders cooperations in climate change adaptation strategies in agriculture and food production in Japan.

  16. Assessing the Groundwater Quality at a Saudi Arabian Agricultural Site and the Occurrence of Opportunistic Pathogens on Irrigated Food Produce

    This study examines the groundwater quality in wells situated near agricultural fields in Saudi Arabia. Fruits (e.g., tomato and green pepper) irrigated with groundwater were also assessed for the occurrence of opportunistic pathogens to determine if food safety was compromised by the groundwater. The amount of total nitrogen in most of the groundwater samples exceeded the 15 mg/L permissible limit for agricultural irrigation. Fecal coliforms in densities > 12 MPN/100 mL were detected in three of the groundwater wells that were in close proximity to a chicken farm. These findings, coupled with qPCR-based fecal source tracking, show that groundwater in wells D and E, which were nearest to the chicken farm, had compromised quality. Anthropogenic contamination resulted in a shift in the predominant bacterial phyla within the groundwater microbial communities. For example, there was an elevated presence of Proteobacteria and Cyanobacteria in wells D and E but a lower overall microbial richness in the groundwater perturbed by anthropogenic contamination. In the remaining wells, the genus Acinetobacter was detected at high relative abundance ranging from 1.5% to 48% of the total groundwater microbial community. However, culture-based analysis did not recover any antibiotic-resistant bacteria or opportunistic pathogens from these groundwater samples. In contrast, opportunistic pathogenic Enterococcus faecalis and Pseudomonas aeruginosa were isolated from the fruits irrigated with the groundwater from wells B and F. Although the groundwater was compromised, quantitative microbial risk assessment suggests that the annual risk incurred from accidental consumption of E. faecalis on these fruits was within the acceptable limit of 10−4. However, the annual risk arising from P. aeruginosa was 9.55 × 10−4, slightly above the acceptable limit. Our findings highlight that the groundwater quality at this agricultural site in western Saudi Arabia is not pristine and that better

    2002-01-01

    Severe stresses are being generated by increasing demand for competing water uses, above all between agriculture and urban needs. Amongst potential solutions considered, two dominated the workshop: virtual water and water reuse. Virtual water implies indirect water use: water-poor countries importing food rather than attempting self-sufficiency and thereby keeping their real water resources for economically more beneficial uses. There are serious political and economic risks associated; one proposed solution is an international virtual water trading council. Improved forms of water reuse, particularly use of treated urban wastewater for irrigation, can maximise the use made of limited supply.

  14. Infrared Spectroscopy as a Versatile Analytical Tool for the Quantitative Determination of Antioxidants in Agricultural Products, Foods and Plants

    PubMed Central

    Cozzolino, Daniel

    2015-01-01

    Spectroscopic methods provide with very useful qualitative and quantitative information about the biochemistry and chemistry of antioxidants. Near infrared (NIR) and mid infrared (MIR) spectroscopy are considered as powerful, fast, accurate and non-destructive analytical tools that can be considered as a replacement of traditional chemical analysis. In recent years, several reports can be found in the literature demonstrating the usefulness of these methods in the analysis of antioxidants in different organic matrices. This article reviews recent applications of infrared (NIR and MIR) spectroscopy in the analysis of antioxidant compounds in a wide range of samples such as agricultural products, foods and plants.

    This report provides some demographic, agricultural and food consumption data for the collective farms ( Kybisheva,'' composed of three villages) in the Oranoe Department, District of Ivankov, Kiev Region. This area is situated approximately 15 km south of the Chernobyl 30-km Exclusion Zone. The levels of {sup 137}Cs are approximately 5--10 curies/km{sup 2}. This data was collected by the Integrated Radioecological Expedition to Chernobyl of the Russian Academy of Sciences as part of the co-operative studies on environmental radiation dose assessment conducted under the US/USSR Joint Co-operative Committee on Civilian Nuclear Reactor Safety (JCCCNRS) established in 1989.

    Trypanocides will continue to play an important role in the control of tsetse fly transmitted trypanosomosis now and in the near future. The drugs are mostly administered by farmers without any veterinary supervision leading to misuse and under dosing of medication, and these could be factors that promote trypanocidal drug resistance (TDR) development. In order to delay or prevent TDR, the Food and Agriculture Organization (FAO) recommended guidelines on trypanocide use. It is not known if these recommended guidelines are adhered to in Itezhi tezhi district of Zambia. A survey was undertaken to examine how socio-economic and environmental factors were associated with adherence to the recommended guidelines on trypanocide use in Itezhi tezhi, Central Zambia. Ninety farmers who use trypanocides were interviewed using a questionnaire to collect their socio-economic characteristics (age, education in years, cattle herd size, competence on trypanocide use and their access to extension on trypanocide use) and trypanocide usage practices while crush pens which they use were stratified according to location, whether in the Game Management Area (GMA) (Mutenda, Itumbi, Kapulwe and Banachoongo) or non-GMA (Iyanda, New Ngoma and Shinampamba) as an environmental factor. Associations and measures of associations to adherence of FAO guidelines were determined. The results showed that 25.6% of the farmers adhered to guidelines by FAO on trypanocide use and that none of the socio-economic factors under investigation were significantly associated with it. Further the farmers that used crush pens that were in the GMA had an 80% reduction in the likelihood of adhering to the FAO guidelines on trypanocide use than those that used crush pens in the non-GMA (AOR 0.20, 95% CI: 0.05-0.81, P=0.02). There was low adherence to the recommended FAO guidelines on trypanocide use and it was associated with the location of the crush pen whether in the GMA or not, as an environmental factor. With

    In CELSS (Controlled Ecological Life Support System), utilization of photosynthetic algae is an effective means for obtaining food and oxygen at the same time. We have chosen Spirulina, a blue-green alga, and have studied possibilities of algae utilization. We have developed an advanced algae cultivation system, which is able to produce algae continuously in a closed condition. Major features of the new system are as follows. (1) In order to maintain homogeneous culture conditions, the cultivator was designed so as to cause a swirl on medium circulation. (2) Oxygen gas separation and carbon dioxide supply are conducted by a newly designed membrane module. (3) Algae mass and medium are separated by a specially designed harvester. (4) Cultivation conditions, such as pH, temperature, algae growth rate, light intensity and quantity of generated oxygen gas are controlled by a computer system and the data are automatically recorded. This equipment is a primary model for ground experiments in order to obtain some design data for space use. A feasibility of algae cultivation in a closed condition is discussed on the basis of data obtained by use of this new system.

  5. The "Lung": a software-controlled air accumulator for quasi-continuous multi-point measurement of agricultural greenhouse gases

    2011-10-01

    We describe the design and testing of a flexible bag ("Lung") accumulator attached to a gas chromatographic (GC) analyzer capable of measuring surface-atmosphere greenhouse gas exchange fluxes in a wide range of environmental/agricultural settings. In the design presented here, the Lung can collect up to three gas samples concurrently, each accumulated into a Tedlar bag over a period of 20 min or longer. Toggling collection between 2 sets of 3 bags enables quasi-continuous collection with sequential analysis and discarding of sample residues. The Lung thus provides a flexible "front end" collection system for interfacing to a GC or alternative analyzer and has been used in 2 main types of application. Firstly, it has been applied to micrometeorological assessment of paddock-scale N2O fluxes, discussed here. Secondly, it has been used for the automation of concurrent emission assessment from three sheep housed in metabolic crates with gas tracer addition and sampling multiplexed to a single GC. The Lung allows the same GC equipment used in laboratory discrete sample analysis to be deployed for continuous field measurement. Continuity of measurement enables spatially-averaged N2O fluxes in particular to be determined with greater accuracy, given the highly heterogeneous and episodic nature of N2O emissions. We present a detailed evaluation of the micrometeorological flux estimation alongside an independent tuneable diode laser system, reporting excellent agreement between flux estimates based on downwind vertical concentration differences. Whilst the current design is based around triplet bag sets, the basic design could be scaled up to a larger number of inlets or bags and less frequent analysis (longer accumulation times) where a greater number of sampling points are required.

  6. Landscape context mediates influence of local food abundance on wetland use by wintering shorebirds in an agricultural valley

    While it is widely understood that local abundance of benthic invertebrates can greatly influence the distribution and abundance of wetland birds, no studies have examined if wetland landscape context can mediate this relationship. We studied the influence of wetland food abundance and landscape context on use of agricultural wetlands by wintering dunlin (Calidris alpina) and killdeer (Charadrius vociferus) in the Willamette Valley of Oregon, USA, over two winters (1999a??2000, 2000a??2001) of differing rainfall and subsequent habitat distribution. We monitored bird use (frequency of occurrence and abundance) at a sample of wetlands differing in local food abundance (density and biomass) and landscape context [adjacent shorebird habitat (defined as ha of wet habitat with less than 50% vegetative cover and within a 2-km radius) and nearest neighbor distance]. We evaluated predictive models for bird use using linear regression and the Cp criterion to select the most parsimonious model. During the dry winter (2000a??2001), dunlin exhibited greater use of sites with higher invertebrate density and biomass but also with more adjacent shorebird habitat and closest to a wetland neighbor. However, neither landscape context nor food abundance were important predictors of dunlin use during the wet winter (1999a??2000). Use of sites by killdeer was unrelated to either local food abundance or landscape context measures during both winters. Our findings contribute to a growing recognition of the importance of landscape structure to wetland birds and highlight a number of implications for the spatial planning and enhancement of wetlands using a landscape approach.

    Earthquakes often cause destructive and unpredictable changes that can affect local hydrology (e.g. groundwater elevation or reduction) and thus disrupt land uses and human activities. Prolific agricultural regions overlie seismically active areas, emphasizing the importance to improve our understanding and monitoring of hydrologic and agricultural systems following a seismic event. A thorough data collection is necessary for adequate post-earthquake crop management response; however, the large spatial extent of earthquake's impact makes challenging the collection of robust data sets for identifying locations and magnitude of these impacts. Observing hydrologic responses to earthquakes is not a novel concept, yet there is a lack of methods and tools for assessing earthquake's impacts upon the regional hydrology and agricultural systems. The objective of this paper is to describe how remote sensing imagery, methods and tools allow detecting crop responses and damage incurred after earthquakes because a change in the regional hydrology. Many remote sensing datasets are long archived with extensive coverage and with well-documented methods to assess plant-water relations. We thus connect remote sensing of plant water relations to its utility in agriculture using a post-earthquake agrohydrologic remote sensing (PEARS) framework; specifically in agro-hydrologic relationships associated with recent earthquake events that will lead to improved water management.

    Bacterial spores have a strong resistance to both chemical and physical hurdles and create a risk for the food industry, which has been tackled by applying high thermal intensity treatments to sterilize food. These strong thermal treatments lead to a reduction of the organoleptic and nutritional properties of food and alternatives are actively searched for. Innovative hurdles offer an alternative to inactivate bacterial spores. In particular, recent technological developments have enabled a new generation of high pressure homogenizer working at pressures up to 400 MPa and thus, opening new opportunities for high pressure sterilization of foods. In this short review, we summarize the work conducted on (ultra) high pressure homogenization (U)HPH to inactivate endospores in model and food systems. Specific attention is given to process parameters (pressure, inlet, and valve temperatures). This review gathers the current state of the art and underlines the potential of UHPH sterilization of pumpable foods while highlighting the needs for future work.

    The rapid increase in human mobilization of phosphorus has raised concerns on both its supply security and its impact on the environment. Increasing the efficiency of phosphorus use is an approach to mitigate the adverse impacts associated with phosphorus consumption. This study estimates the life-cycle phosphorus use-efficiency of the US food system. A framework for accounting phosphorus stocks and flows is developed, and the account was populated with data. A map of phosphorus stocks and flows around the US food system is drawn and phosphorus use-efficiency was calculated. The results show that only 15% of the total phosphorus extracted from nature for the provision of food is eventually ingested by humans and the rest is lost to the environment. Major losses occur during the livestock, meat and dairy production and crop cultivation stage, where about 66% of the total phosphorus extracted is lost to the environment. The results also show that other losses of phosphorus including household food waste, mining waste, and fertilizer manufacturing waste are not negligible, which constitute about 19% of the total phosphorus extracted for food purpose. A data quality assessment and sensitivity analysis was performed to identify data quality hotspots and to envisage effective measures to improving phosphorus use-efficiency. Improving yields of livestock and crop cultivation without additional phosphorus input and reducing household food waste are shown to be effective measures to improve life-cycle phosphorus use-efficiency. The results highlight the need of a concerted effort by all entities along the life-cycle for efficient use of phosphorus. PMID:21333320

    Beginning in the 1980s with NASA's Controlled Ecological Life Support System (CELSS) Program and later the 1990s and early 2000s with the Advanced Life Support Project, NASA conducted extensive testing with crops in controlled environment conditions. One series of tests conducted at Kennedy Space Center used a large chamber with vertically stacked shelves to support hydroponic growing trays, with a bank of electric lamps above each shelf. This is essentially the same approach that has become popular for use in so-called vertical agriculture systems, which attempts to optimize plant production in a fixed volume. Some of the findings and commonalities of NASA's work during this period and how it overlaps with current interests in vertical agriculture will be presented in the talk.

    Drought is an extreme climatic situation where there is a water shortage arising due to sub-normal rainfall, erratic distribution of precipitation, increased water supply demand, etc. India faced several years of drought in last six decades. As Indian agriculture is largely dependent on the monsoon, a slight change affects production as well as crop yield drastically. Statistical analysis is important for mapping the drought prone areas. Raichur district of the northern interior state of Karnataka is a drought-prone region where the economy is mainly based on agriculture. So, the uneven distribution of rainfall as well as the delay in the arrival of the southwest monsoon adversely affects the growth stage of crops which result in a decline in crop production. The effect of drought on the agriculture for the past decade has been analyzed using crop productivity data. When the production rate of Raichur district was studied for the years 1998 to 2009, it was seen that major crops like rice and jowar faced a decline in its production during the years 2002 and 2003, whereas bajra, maize, etc. mostly decreased in the year 2004.

    The presence of DDT and derivatives in the food web of freshwater ecosystems of Rangsit agricultural area, Pathum Thani Province, Thailand were investigated from June 2004 to May 2007. By using gas chromatography (GC) with micro electron capture detector (mu ECD), DDT and derivatives in water, sediment, and fifteen indicator species i.e., 2 producers; Eichhornia crassipes and plankton (phyto- and zoo- plankton), an herbivore; Trichogaster microlepis (3) 3 omnivores; Trichogaster trichopterus, Oreochromis niloticus, and Puntius gonionotus, 6 carnivores; Channa striatus, Oxyeleotris marmoratus, Macrognathus siamensis, Parambassis siamensis, Anabas testudineus, and Pristolepis fasciatus, and 3 detritivores; Macrobrachium lanchesteri, Pomacea sp., and Filopaludina mertensi were measured. Results show low concentration levels (part per billion) of DDT & derivatives in each food web compartment i.e. water, sediment, aquatic plant, plankton, fish, and invertebrates. Magnification patterns, i.e. bioconcentration, bioaccumulation, and biomagnification, based on habitat and foraging behavior of selected freshwater species indicates that DDT & derivatives can accumulate and be magnified through the food chain from the lowest up to the highest trophic level. Therefore, the presence of residues and the evidence of magnification patterns can be observed as ecological indicators for evaluating ecological health risk.

  14. [Animal health in organic agriculture: new guidelines and perspectives for food animal practitioners].

    In the last decade, the organic agriculture in Switzerland has been substantially increased due to the interest of consumer and financial incentives of the federation. Ruminants take directly or indirectly the largest part from grassland used within the organic managed surfaces. As the contacts between veterinary practice and organic agriculture has increased, the potential for veterinary activity in this area has developed considerably. The organic agriculture guidelines stipulate that all the preventive measures should be taken in feeding, keeping and breeding to insure animal health safety. This requires veterinary services for herd management. The organic status of a farm affects veterinary practice also in the form of alternative therapy/drugs administration and measures like dehorning and tail-docking. An important point in organic managed herds requests that treatment of animals should depend on alternative medical preparations or procedures based on veterinarian's experience and also on the therapeutic effect on the animal species concerned as well as on the disease. However, there are no restrictions on the veterinarian to use registered drugs as long as no alternative therapy, according to experience and possible success, is available to treat the animals. The prophylactic administration of allopathic veterinary drugs is not permissible. Further features in organic farms regarding the use of drugs are the keeping of withholding/withdrawal time, the documentation and the treatment frequency tolerated by organic marketing. Despite the above measures, the animal health has a priority regardless of its organic status. Although management of organic farms represent a unique responsibility, there are still obvious deficits in the education of veterinary practitioners for this new situation. However, in the future the extension of veterinary activity to include the alternative medical therapy should be regarded for the practitioner as a challenge and an

  16. Assessment of Food and Nutrition Related Descriptors in Agricultural and Biomedical Thesauri

    NASA Astrophysics Data System (ADS)

    Bartol, Tomaz

    Food- and human nutrition-related subject headings or descriptors of the following thesauri-databases are assessed: NAL Thesaurus/Agricola, Agrovoc/Agris, CAB Thesaurus, FSTA Thesaurus, MeSH/Medline. Food concepts can be represented by thousands of different terms but subject scope of a particular term is sometimes vague. There exist important differences among thesauri regarding same or similar concept. A term that represents narrower or broader concept in one thesaurus can in another stand for a related concept or be non-existent. Sometimes there is no clear implication of differences between scientific (Latin) and common (English) names. Too many related terms can confuse end-users. Thesauri were initially employed mostly by information professionals but can now be used directly by users who may be unaware of differences. Thesauri are assuming new roles in classification of information as metadata. Further development towards ontologies must pay constant attention to taxonomic problems of representation of knowledge.

On the other hand, the responsibility of "Producers-Manufacturers-Consumers"'s bond is essential for the consumer and a "ecologico-toxico-economical" safety for the Producers-Manufacturers to target low residues of pesticides.

  18. Glycolipid biosurfactants: main properties and potential applications in agriculture and food industry.

    PubMed

    Mnif, Inès; Ghribi, Dhouha

    2016-10-01

    Glycolipids, consisting of a carbohydrate moiety linked to fatty acids, are microbial surface active compounds produced by various microorganisms. They are characterized by high structural diversity and have the ability to decrease the surface and interfacial tension at the surface and interface, respectively. Rhamnolipids, trehalolipids, mannosylerythritol lipids and cellobiose lipids are among the most popular glycolipids. They have received much practical attention as biopesticides for controlling plant diseases and protecting stored products. As a result of their antifungal activity towards phytopathogenic fungi and larvicidal and mosquitocidal potencies, glycolipid biosurfactants permit the preservation of plants and plant crops from pest invasion. Also, as a result of their emulsifying and antibacterial activities, glycolipids have great potential as food additives and food preservatives. Furthermore, the valorization of food byproducts via the production of glycolipid biosurfactant has received much attention because it permits the bioconversion of byproducts on valuable compounds and decreases the cost of production. Generally, the use of glycolipids in many fields requires their retention from fermentation media. Accordingly, different strategies have been developed to extract and purify glycolipids. © 2016 Society of Chemical Industry. PMID:27098847

    One complicating factor in cocaine addiction may be concurrent exposure and potential dependence on nicotine. The aim of the present study was to determine the effects of continuous nicotine treatment and subsequent termination on cocaine versus food choice in rhesus monkeys (Macaca mulatta). For comparison, we also determined effects of the nicotinic receptor antagonist mecamylamine on cocaine versus food choice during continuous saline and nicotine treatment. Rhesus monkeys (N = 3) responded under a concurrent schedule of food pellet (1 g) and intravenous cocaine (0-0.1 mg/kg/injection) availability. Saline and ascending nicotine doses (0.1-1.0 mg/kg/hr, intravenous) were continuously infused for 7-day treatment periods and separated by 24-hr saline treatment periods. Acute effects of mecamylamine (0.32-1.8 mg/kg, intramuscular, 15 min pretreatment) were determined during continuous saline and 0.32-mg/kg/hr nicotine treatments. During saline treatment, cocaine maintained a dose-dependent increase in cocaine choice. Nicotine treatment did not alter cocaine versus food choice. In contrast, preference of 0.032 mg/kg/injection cocaine was attenuated 24 hr following termination of 0.32-mg/kg/hr nicotine treatment, despite no somatic abstinence signs being observed. Acute mecamylamine enhanced cocaine choice during saline treatment and mainly suppressed rates of behavior during nicotine treatment. Overall, continuous nicotine exposure, up to 1 mg/kg/hr, does not enhance cocaine choice and does not produce nicotine dependence, as demonstrated by the lack of abstinence signs. PMID:26098473

    2002-07-17

    Pest management techniques have evolved over the past 50 years. Inorganic chemical pesticides were replaced by synthetic organic chemicals, and now biopesticides constitute a significant part of pest management technology. Requirements for the regulatory approval of pesticides changed dramatically in 1996 with the passage of the Food Quality Protection Act (FQPA). The FQPA directs the U.S. Environmental Protection Agency (EPA) to make more rigorous and conservative evaluation of risks and hazards and mandates a special emphasis on the safety of infants and children. The EPA provides incentives for the industry to register materials that are designated "reduced risk". The future for the registrant industry will include continued reduction in numbers of registrants through mergers and acquisitions. Conventional chemicals will remain as important pest management components, and the processes of combinatorial chemistry and high-throughput bioassays will allow the rapid synthesis and testing of large numbers of candidate compounds. Biopesticides will become more important tools in pest management, with microbial pesticides and transgenic crops being likely to play important crop protection roles. There will be a continuing need for research-based approaches to pest control.

    Previous studies have combined climate, crop and economic models to examine the impact of climate change on agricultural production and food security, but results have varied widely due to differences in models, scenarios and data. Recent work has examined (and narrowed) these differences through systematic model intercomparison using a high-emissions pathway to highlight the differences. New work extends that analysis to cover a range of plausible socioeconomic scenarios and emission pathways. Results from three general circulation models are combined with one crop model and five global economic models to examine the global and regional impacts of climate change on yields, area, production, prices and trade for coarse grains, rice, wheat, oilseeds and sugar to 2050. Results show that yield impacts vary with changes in population, income and technology as well as emissions, but are reduced in all cases by endogenous changes in prices and other variables.

    Extreme temperatures and exposure to agricultural pesticides are becoming more frequent and intense under global change. Their combination may be especially problematic when animals suffer food limitation. We exposed Coenagrion puella damselfly larvae to a simulated heat wave combined with food limitation and subsequently to a widespread agricultural pesticide (chlorpyrifos) in an indoor laboratory experiment designed to obtain mechanistic insights in the direct effects of these stressors in isolation and when combined. The heat wave reduced immune function (activity of phenoloxidase, PO) and metabolic rate (activity of the electron transport system, ETS). Starvation had both immediate and delayed negative sublethal effects on growth rate and physiology (reductions in Hsp70 levels, total fat content, and activity levels of PO and ETS). Exposure to chlorpyrifos negatively affected all response variables. While the immediate effects of the heat wave were subtle, our results indicate the importance of delayed effects in shaping the total fitness impact of a heat wave when followed by pesticide exposure. Firstly, the combination of delayed negative effects of the heat wave and starvation, and the immediate negative effect of chlorpyrifos considerably (71%) reduced larval growth rate. Secondly and more strikingly, chlorpyrifos only caused considerable (ca. 48%) mortality in larvae that were previously exposed to the combination of the heat wave and starvation. This strong delayed synergism for mortality could be explained by the cumulative metabolic depression caused by each of these stressors. Further studies with increased realism are needed to evaluate the consequences of the here-identified delayed synergisms at the level of populations and communities. This is especially important as this synergism provides a novel explanation for the poorly understood potential of heat waves and of sublethal pesticide concentrations to cause mass mortality.

    Incorporating knowledge of the surrounding landscape can further the understanding of stream processes. This is particularly true in areas like the Midwest where human alteration of the landscape, such as conversion of natural cover types into cultivated row crops, is widespread. When assessing stream health, the composition and structure of biological communities themselves often are the best indicators of water quality. Previous work in Hurricane Creek (Coles and Cumberland Counties, IL) demonstrated significant differences in water chemistry and community metabolism between sites subject to differing intensities of farming in the upstream watershed. Our objective was to examine differences in fish and invertebrate communities at four sites along the stream representing varying degrees of agricultural land-use. Fish were sampled using electroseining techniques and invertebrates were collected using the 20-jab method in each of four seasons. Sites were compared using fish and invertebrate community metrics, including indices of biotic integrity (IBI, MBI). Stable isotope analyses were also performed to quantify differences in food-web structure in streams draining watersheds characterized by different degrees of agricultural land-use. This study improves understanding of how landscape alteration impacts stream biota and will facilitate more informed decisions concerning stream rehabilitation.

    Objectives Industrial food animal production (IFAP) operations adversely impact environmental public health through air, water, and soil contamination. We sought to determine how state permitting and agriculture agencies respond to these public health concerns. Methods We conducted semi-structured qualitative interviews with staff at 12 state agencies in seven states, which were chosen based on high numbers or rapid increase of IFAP operations. The interviews served to gather information regarding agency involvement in regulating IFAP operations, the frequency and type of contacts received about public health concerns, how the agency responds to such contacts, and barriers to additional involvement. Results Permitting and agriculture agencies’ responses to health-based IFAP concerns are constrained by significant barriers including narrow regulations, a lack of public health expertise within the agencies, and limited resources. Conclusions State agencies with jurisdiction over IFAP operations are unable to adequately address relevant public health concerns due to multiple factors. Combining these results with previously published findings on barriers facing local and state health departments in the same states reveals significant gaps between these agencies regarding public health and IFAP. There is a clear need for regulations to protect public health and for public health professionals to provide complementary expertise to agencies responsible for regulating IFAP operations.

    Mo-CBP3 is an antifungal protein produced by Moringa oleifera which has been investigated as potential candidate for developing transgenic crops. Before the use of novel proteins, food safety tests must be conducted. This work represents an early food safety assessment of Mo-CBP3, using the two-tiered approach proposed by ILSI. The history of safe use, mode of action and results for amino acid sequence homology using the full-length and short contiguous amino acids sequences indicate low risk associated to this protein. Mo-CBP3 isoforms presented a reasonable number of alignments (>35% identity) with allergens in a window of 80 amino acids. This protein was resistant to pepsin degradation up to 2 h, but it was susceptible to digestion using pancreatin. Many positive attributes were presented for Mo-CBP3. However, this protein showed high sequence homology with allergens and resistance to pepsin digestion that indicates that further hypothesis-based testing on its potential allergenicity must be done. Additionally, animal toxicity evaluations (e.g. acute and repeated dose oral exposure assays) must be performed to meet the mandatory requirements of several regulatory agencies. Finally, the approach adopted here exemplified the importance of performing an early risk assessment of candidate proteins for use in plant transformation programs.

    A method has been developed to identify pesticide residues and foodstuffs for inclusion in national monitoring programs with different priority levels. It combines two chronic dietary intake indicators: ATMDI based on maximum residue levels and agricultural uses, and EDI on food contamination data. The mean and 95th percentile of exposure were calculated for 490 substances using individual and national consumption data. The results show that mean ATMDI exceeds the acceptable daily intake (ADI) for 10% of the pesticides, and the mean upper-bound EDI is above the ADI for 1.8% of substances. A seven-level risk scale is presented for substances already analyzed in food in France and substances not currently sought. Of 336 substances analyzed, 70 pesticides of concern (levels 2-5) should be particularly monitored, 22 of which are priority pesticides (levels 4 and 5). Of 154 substances not sought, 36 pesticides of concern (levels 2-4) should be included in monitoring programs, including 8 priority pesticides (level 4). In order to refine exposure assessment, analytical improvements and developments are needed to lower the analytical limits for priority pesticide/commodity combinations. Developed nationally, this method could be applied at different geographic scales.

    A design proposal for a HCEFN Hospital Continuous Education in Feeding and Nutrition, along with the educational intervention model developed and conducted at the "Hermanos Ameijieras" Hospital (Havana City, Cuba), and some of the results obtained after its implementation between 1997-2004, are presented in this article. The System design should include three levels of different and increasing complexity, depending on the level of knowledge, capabilities and aptitudes exhibited by hospital actors. The described system should also accommodate inter- and intra-disciplinary forms of education, learning and training aimed not only to increase the proficiency of actors in the recognition and treatment of hospital malnutrition, but also to foster group performance. The operation of a HCEFN at the hospital of the authors's affiliation has showed the feasibility of conducting such educational interventions oriented to foster Good Practices for Feeding and Nutrition of the hospitalized patients.

    We compared the cold enrichment (CE) and U.S. Department of Agriculture (USDA) methods for isolating Listeria monocytogenes by examining 402 food samples. The food samples were collected from refrigerators of listeriosis patients as part of a multistate active surveillance project to determine the role of foods in sporadic listeriosis in the United States. L. monocytogenes was isolated from 51 food samples (13%). The USDA method was significantly better (P less than 0.001) than the CE method. The isolation efficiencies of the USDA and CE methods were 96 and 59%, respectively. Quantitation of L. monocytogenes in the food samples revealed that many food samples containing less than 0.3 CFU/g were negative as determined by the CE method but positive as determined by the USDA method.

    Contemporary animal agriculture is increasingly criticized on ethical grounds. Consequently, current policy and legislative discussions have become highly controversial as decision makers attempt to reconcile concerns about the impacts of animal production on animal welfare, the environment, and on the efficacy of antibiotics required to ensure human health with demands for abundant, affordable, safe food. Clearly, the broad implications for US animal agriculture of what appears to be a burgeoning movement relative to ethical food production must be understood by animal agriculture stakeholders. The potential effects of such developments on animal agricultural practices, corporate marketing strategies, and public perceptions of the ethics of animal production must also be clarified. To that end, it is essential to acknowledge that people's beliefs about which food production practices are appropriate are tied to diverse, latent value systems. Thus, relying solely on scientific information as a means to resolve current debates about animal agriculture is unlikely to be effective. The problem is compounded when scientific information is used inappropriately or strategically to advance a political agenda. Examples of the interface between science and ethics in regards to addressing currently contentious aspects of food animal production (animal welfare, antimicrobial use, and impacts of animal production practices on the environment) are reviewed.

    2015-01-01

    One of the major breakthroughs in the history of medicine is undoubtedly the discovery of antibiotics. Their use in animal husbandry and veterinary medicine has resulted in healthier and more productive farm animals, ensuring the welfare and health of both animals and humans. Unfortunately, from the first use of penicillin, the resistance countdown started to tick. Nowadays, the infections caused by antibiotic-resistant bacteria are increasing, and resistance to antibiotics is probably the major public health problem. Antibiotic use in farm animals has been criticized for contributing to the emergence of resistance. The use and misuse of antibiotics in farm animal settings as growth promoters or as nonspecific means of infection prevention and treatment has boosted antibiotic consumption and resistance among bacteria in the animal habitat. This reservoir of resistance can be transmitted directly or indirectly to humans through food consumption and direct or indirect contact. Resistant bacteria can cause serious health effects directly or via the transmission of the antibiotic resistance traits to pathogens, causing illnesses that are difficult to treat and that therefore have higher morbidity and mortality rates. In addition, the selection and proliferation of antibiotic-resistant strains can be disseminated to the environment via animal waste, enhancing the resistance reservoir that exists in the environmental microbiome. In this review, an effort is made to highlight the various factors that contribute to the emergence of antibiotic resistance in farm animals and to provide some insights into possible solutions to this major health issue.

    A hydrogen economy system is described which utilizes effectively the by-product of hydrogen combustion even more important than the energy produced, water. This system is open port, multimodal in application (dependent upon local needs and strategies), retrofittable with new technology in time, versatile in its application and rich in profittable by-products. It is environmentally and ecologically sound, being essentially based upon the four elements of Greek mythology: earth, air, fire and water. It is a rare blending of old principles of physics with new technology. The final products are; enormous new agribusiness in previously barren geographical areas, producing large increases in biomass production for fuel or food, large increases in jobs in areas in underemployment, and large increases in federal and local government tax base in previously unproductive revenue areas, in addition to electrical energy production. When powered by solar electrolysis or solar photolysis its cost should be minimal when prorated over the effective lifetime of solar energy with minimal maintainance costs.

    One of the major breakthroughs in the history of medicine is undoubtedly the discovery of antibiotics. Their use in animal husbandry and veterinary medicine has resulted in healthier and more productive farm animals, ensuring the welfare and health of both animals and humans. Unfortunately, from the first use of penicillin, the resistance countdown started to tick. Nowadays, the infections caused by antibiotic-resistant bacteria are increasing, and resistance to antibiotics is probably the major public health problem. Antibiotic use in farm animals has been criticized for contributing to the emergence of resistance. The use and misuse of antibiotics in farm animal settings as growth promoters or as nonspecific means of infection prevention and treatment has boosted antibiotic consumption and resistance among bacteria in the animal habitat. This reservoir of resistance can be transmitted directly or indirectly to humans through food consumption and direct or indirect contact. Resistant bacteria can cause serious health effects directly or via the transmission of the antibiotic resistance traits to pathogens, causing illnesses that are difficult to treat and that therefore have higher morbidity and mortality rates. In addition, the selection and proliferation of antibiotic-resistant strains can be disseminated to the environment via animal waste, enhancing the resistance reservoir that exists in the environmental microbiome. In this review, an effort is made to highlight the various factors that contribute to the emergence of antibiotic resistance in farm animals and to provide some insights into possible solutions to this major health issue.
