Publicly available benchmark data and metric evaluation approaches have been instrumental in enabling research to advance state of the art methods for remote sensing applications in urban 3D modeling. Most publicly available benchmark datasets have consisted of high resolution airborne imagery and lidar suitable for 3D modeling on a relatively modest scale. To enable research in larger scale 3D mapping, we have recently released a public benchmark dataset with multi-view commercial satellite imagery and metrics to compare 3D point clouds with lidar ground truth. We now define a more complete metric evaluation pipeline developed as publicly available open source software to assess semantically labeled 3D models of complex urban scenes derived from multi-view commercial satellite imagery. Evaluation metrics in our pipeline include horizontal and vertical accuracy and completeness, volumetric completeness and correctness, perceptual quality, and model simplicity. Sources of ground truth include airborne lidar and overhead imagery, and we demonstrate a semi-automated process for producing accurate ground truth shape files to characterize building footprints. We validate our current metric evaluation pipeline using 3D models produced using open source multi-view stereo methods. Data and software is made publicly available to enable further research and planned benchmarking activities.

Increasing demand for settlements steamed by population growth declines the quality of the environment specifically at urban area. The existing spatial planning could not able to prevent the change of land use for settlement and other infrastructures. The Act no. 26 of 2007 on spatial planning stipulates that green open space must reach 30% of the total area, consisting of 20% public open space and 10% private open space. The existing condition of urban area at Kendal Regency reach 245,6 million m2 with 88.145,5 m2 green open space or 0,036% out of total area. An effort to increase green open space in urban areas taken by the Government of Kendal Regency is by promulgating a local regulation stipulating that each housing developer request a building permit is obliged to provide a green open space at least 10 percent of the total housing area. This paper reviews the effectiveness of building permit regulation, the problems encountered and the concept proposed to make the local regulation work. The area of sample taken is three urban districts out of five urban districts, the resource persons chosen are those from relevant offices (Dinas) involved at the implementation of the local regulation. The data collection techniques employed are the Analytical Hierarchy Process (AHP), Geographic Information System (GIS) technology, social observation and informal interview. The data gathered will be analyzed quantitatively and qualitatively.

Public-display systems are still far from being a medium for meeting people's diverse communication goals. Moving toward open displays will require publication paradigms that can overcome the challenges of meaningful engagement and enable users to fully understand and control the publication process. The metaphors of pins and posters have inspired two complementary paradigms for public displays. Researchers implemented these paradigms in the Instant Places system, which they deployed on 10 displays in diverse urban locations for six months. They collected user and system data regarding the users' practices. The findings improve the understanding of what might drive user-generated content in networks of urban displays. Such knowledge can inform the design of tools and procedures for situated publication in public displays.

The presence or absence of amenities in local neighbourhood environments can either promote or restrict access to opportunities to engage in healthy and/or less healthy behaviours. Rurality is thought to constrain access to facilities and services. This study investigated whether the presence and density of environmental amenities related to physical activity and eating behaviours differs between socioeconomically disadvantaged urban and rural areas in Victoria, Australia. We undertook cross-sectional analysis of environmental data collected in 2007-08 as part of the Resilience for Eating and Activity Despite Inequality (READI) study. These data were sourced and analysed for 40 urban and 40 rural socioeconomically disadvantaged areas. The variables examined were the presence, raw count, count/km2, and count/'000 population of a range of environmental amenities (fast-food restaurants, all supermarkets (also separated by major chain and other supermarkets), greengrocers, playgrounds, gyms/leisure centres, public swimming pools and public open spaces). A greater proportion of urban areas had a fast-food restaurant and gym/leisure centre present while more rural areas contained a supermarket and public swimming pool. All amenities examined (with the exception of swimming pools) were more numerous per km2 in urban areas, however rural areas had a greater number of all supermarkets, other supermarkets, playgrounds, swimming pools and public open space per '000 population. Although opportunities to engage in healthy eating and physical activity exist in many rural areas, a lower density per km2 suggests a greater travel distance may be required to reach these.

A limited amount of research has examined the effect of changing public open spaces on active living. This paper will present the study protocol of a community-based intervention study co-designed in an interdisciplinary collaboration with community members to develop urban installations highly tailored to promote active living among children (10-13-years-old) and seniors (>60-years-old) in a deprived neighbourhood in Copenhagen. The study builds on a quasi-experimental study design with two sub-studies: 1) a children study and 2) a senior study. The interventions will be developed, designed and implemented in collaboration with local children and seniors, respectively, using different co-design tools and methods. We will evaluate the effect of the interventions on children's and senior's use of the new-built urban installations using accelerometers in combination with GPS as well as systematic observation using the System for Observing Play and Recreation in Communities (SOPARC). A process evaluation with focus groups consisting of the various stakeholders in the two sub-studies will be used to gain knowledge of the intervention processes. The paper presents new approaches in the field of public open space interventions through interdisciplinary collaboration, participatory co-design approach and combination of measurements. Using both effect and process evaluations the study will provide unique insights in the role and importance of the interdisciplinary collaboration, participatory processes, and tailoring changes in public open space to local needs and wishes. These results can be used to guide urban renewal projects in deprived neighbourhoods in the future. Retrospectively registered with study ID ISRCTN50036837 . Date of registration: 16 December 2016.

Bluetooth as a Playful Public Art Interface

NASA Astrophysics Data System (ADS)

Stukoff, Maria N.

This chapter investigates how the application of emergent communication technologies assisted in the design of playful art experience in a public place. Every Passing Moment (EPM), was a mobile public artwork that tracked and recorded any discoverable Bluetooth device to automatically seed a flower in a virtual garden projected onto an urban screen. The EPM was the first public art work to run blu_box, a custom-designed Bluetooth system for mobile telephony. The aim of blu_box was to build a system that supported playful interactions between the public and an urban screen, openly accessible to anyone with a Bluetooth-enabled mobile phone. This participatory engagement was observed in EPM on three levels, namely; unconscious, conscious, and dynamic play. Furthermore, this chapter highlights how sound and face-to-face communication proved imperative in the play dynamics of EPM. In conclusion, this chapter proposes ways in which the use of emergent communication technologies in public places, especially when interfaced with urban screening platforms, can construct playful city spaces for the public at large.

The lack of public space is one of the main problems in the big cities in Indonesia. Urban kampungas part of the city is also no exception. Rapid growth on population sparks uncontrollable physical development that erode open space inside urbankampung. Sometimes, what is left is just neglected space which don‟t „live‟ and far from the definition of public space. Mural art has been existed since the beginning of human civilization. Now, it has evolved into one of the popular urban art. The previous research has proven that the process of urban art making through participatory approach could trigger community interaction in a space. Interaction itself is a main factor that may trigger the establishmentof a public space. With the same method, this research attempts to build mural in a neglected space inside urbankampung named Palsigunung. After all of the process done, the space still haven‟t changed from the previous condition, which is still a neglected space. Together with facilitator, kampung‟s residents need to be involved identifying the problem and also the solution to the lack of public space in their kampung. Particularly for urban kampungPalsigunung, the needed solution might not be mural.

Institutional property rights structure, common pool resource (CPR), tragedy of the urban commons: A Review

NASA Astrophysics Data System (ADS)

Ling, G.; Ho, C. S.; Ali, H. M.

2014-02-01

There have been a plethora of researches on the significance of public open space (POS) in contributing to societies' sustainability. However, by virtue of identified maladaptive policy-based-property rights structure, such a shared good becomes vulnerable to tragedy of the urban commons (overexploitation) that subsequently leads to burgeoning number of mismanaged POS e.g., degraded and unkempt urban public spaces. By scrutinising the literatures within property rights domain and commons resources, an objective is highlighted in this paper which is to insightfully discourse institutional property rights structure pertaining to the mechanism, roles and interrelationship between property-rights regimes, bundle of property rights and resource domains; types of goods on how they act upon and tie in the POS with the social quandary. In summary, urban POS tragedy can potentially be triggered by the institutional structure especially if the ownership is left under open-access resource regime and ill-defined property rights which both successively constitute the natures of Common Pool Resource (CPR) within the commons, POS. Therefore, this paper sparks an idea to policy makers that property rights structure is a determinant in sustainably governing the POS in which adaptive assignment of property regimes and property rights are impelled.

The Impact of Large Urban Structural Elements on Traffic Flow   a Case Study of Danwei and Xiaoqu in Shanghai

NASA Astrophysics Data System (ADS)

Lyu, H.; Ding, L.; Fan, H.; Meng, L.

2017-09-01

Danwei (working unit) and Xiaoqu (residential community) are two typical and unique structural urban elements in China. The interior roads of Danwei and Xiaoqu are usually not accessible for the public. Recently, there is a call for opening these interior roads to the public to improve road network structure and optimize traffic flow. In this paper we investigate the impact of Danwei and Xiaoqu on their neighbouring traffic quantitatively. By taking into consideration of origins and destinations (ODs) distributions and route selection behaviours (e.g., shortest paths), we propose an extended betweenness centrality to investigate the traffic flow in two scenarios 1) the interior roads of Danwei and Xiaoqu are excluded from urban road network, 2) the interior roads are integrated into road network. A Danwei and a Xiaoqu in Shanghai are used as the study area. The preliminary results show the feasibility of our extended betweenness centrality in investigating the traffic flow patterns and reveal the quantitative changes of the traffic flow after opening interior roads.

This study investigates the joint effect of atmospheric conditions and urban morphology, expressed as the Sky View Factor (SVF), on intra-urban variability. The study has been carried out in Glasgow, UK, a shrinking city with a maritime temperate climate type, and findings could guide future climate adaptation plans in terms of morphology and services provided by the municipality to overcome thermal discomfort in outdoor settings. In this case, SVF has been used as an indicator of urban morphology. The modified Pasquill-Gifford-Turner (PGT) classification system was adopted for classifying the temperature monitoring periods according to atmospheric stability conditions. Thirty two locations were selected on the basis of SVF with a wide variety of urban shapes (narrow streets, neighbourhood green spaces, urban parks, street canyons and public squares) and compared to a reference weather station during a total of twenty three transects during late spring and summer in 2013. Maximum daytime intra-urban temperature differences were found to be strongly correlated with atmospheric stability classes. Furthermore, differences in air temperature are noticeable in urban canyons, with a direct correlation to the site's SVF (or sky openness) and with an inverse trend under open-air conditions.

Historic urban sites are set by cultural and social diversities, generating multiple activities and use and access to these sites should be available to all people including those with disabilities. Taking into consideration that using the same methodology that was used in different historic sites researches with positive results facilitates replication, we aimed to develop methodological procedures that identify conditions of physical accessibility in open public spaces and access to public buildings in historic urban sites to support proposals about design requirements for improvements to the problems diagnosed and control inadequacies of the physical environment. The study methods and techniques from different areas of knowledge culminated in a proposal built with an emphasis on user participation that could be applied with low cost and in relatively short period of time.

A growing number of cities are now making urban data freely available to the public. Besides promoting transparency, these data can have a transformative effect in social science research as well as in how citizens participate in governance. These initiatives, however, are fairly recent and the landscape of open urban data is not well known. In this study, we try to shed some light on this through a detailed study of over 9,000 open data sets from 20 cities in North America. We start by presenting general statistics about the content, size, nature, and popularity of the different data sets, and then examine in more detail structured data sets that contain tabular data. Since a key benefit of having a large number of data sets available is the ability to fuse information, we investigate opportunities for data integration. We also study data quality issues and time-related aspects, namely, recency and change frequency. Our findings are encouraging in that most of the data are structured and published in standard formats that are easy to parse; there is ample opportunity to integrate different data sets; and the volume of data is increasing steadily. But they also uncovered a number of challenges that need to be addressed to enable these data to be fully leveraged. We discuss both our findings and issues involved in using open urban data.

In this paper, we demonstrate why and how both temporality and multimodality should be integrated in health related studies that include accessibility perspective, in this case healthy food accessibility. We provide evidence regarding the importance of using multimodal spatio-temporal accessibility measures when conducting research in urban contexts and propose a methodological approach for integrating different travel modes and temporality to spatial accessibility analyses. We use the Helsinki metropolitan area (Finland) as our case study region to demonstrate the effects of temporality and modality on the results. Spatial analyses were carried out on 250 m statistical grid squares. We measured travel times between the home location of inhabitants and open grocery stores providing healthy food at 5 p.m., 10 p.m., and 1 a.m. using public transportation and private cars. We applied the so-called door-to-door approach for the travel time measurements to obtain more realistic and comparable results between travel modes. The analyses are based on open access data and publicly available open-source tools, thus similar analyses can be conducted in urban regions worldwide. Our results show that both time and mode of transport have a prominent impact on the outcome of the analyses; thus, understanding the realities of accessibility in a city may be very different according to the setting of the analysis used. In terms of travel time, there is clear variation in the results at different times of the day. In terms of travel mode, our results show that when analyzed in a comparable manner, public transport can be an even faster mode than a private car to access healthy food, especially in central areas of the city where the service network is dense and public transportation system is effective. This study demonstrates that time and transport modes are essential components when modeling health-related accessibility in urban environments. Neglecting them from spatial analyses may lead to overly simplified or even erroneous images of the realities of accessibility. Hence, there is a risk that health related planning and decisions based on simplistic accessibility measures might cause unwanted outcomes in terms of inequality among different groups of people.

Rural-urban inequalities in China have been widening over the past few decades. Compared to their urban counterparts, rural residents may encounter various barriers to equal opportunities to effectively engage in physical activity. This study examines the rural-urban disparity in physical activity, proximity and satisfaction with local exercise facilities. An in-person survey was conducted in 29 counties of 10 Chinese provinces in 2012. Five thousand questionnaires were administered by trained staff with a completion rate of 82.1%. The complete sample includes 1661 rural and 2446 urban residents. Eight dichotomous outcome measures were used, pertaining to leisure-time physical activity engagement; proximity to the nearest exercise facility from home; satisfaction level with the quantity, variety, fee levels, opening hours, and daily management and services of nearby exercise facilities; and satisfaction level with the local public sports service system. Nearest-neighbor matching was performed to match rural residents with urban residents by observed individual sociodemographics, including gender, age, education level and residential province. Pearson's χ2 test was used to assess the difference in sociodemographics and outcome measures between rural and urban residents before and after matching. Before nearest-neighbor matching, the frequency distributions of age and education level are significantly different between rural and urban residents (both p<0.0001). After matching, the differences in the frequency distributions between rural and urban residents become statistically non-significant for all observed sociodemographics: gender (p=0.170), age (p=0.934), education level (p=0.244) and residential province (p=1.000). Compared to their matched urban counterparts, rural residents are 8.1% (p<0.0001) more likely to be physically inactive in their leisure time and 5.8% (p=0.005) less likely to live within 30-minute walking distance to the nearest exercise facility. Rural residents are 15.7%, 15.7%, 8.6%, 13.5% and 14.7% more likely to be unsatisfied with the quantity, variety, fee levels, opening hours, and daily management and services of nearby exercise facilities, and 16.1% more likely to be unsatisfied with the local public sports service system than matched urban residents (all p<0.0001). Substantial rural-urban disparities tend to be present in leisure-time physical activity, proximity to the nearest exercise facility, and satisfaction level with exercise facilities and the public sports service system. Policy interventions are warranted to improve the accessibility and affordability of local exercise facilities in rural areas as a way to promote physical activity among Chinese rural residents and reduce disparities.

Mobility and accessibility are crucial indicators of urban development. Public transport in the urban areas came into existence to fulfil transportation needs as well as mobility and accessibility demands. Ridership can be affected by the quality and quantity of transit service. However, technical improvements are needed for such as real-time bus information, controlling run time and headway delay. Thus, this paper is aimed to carry out a preliminary survey to determine the problems of school shuttle bus that faced by the students in a selected educational institution, their perceptions of using shuttle bus tracking and information mobile application and impacts of real-time information of public transits on bus ridership and towards smart mobility solutions. Efficient public transportation system needs further investigation about the role of mobile application for the bus tracking system in supporting smart mobility actions and real-time information. The proposed application also provides a smart solution for the management of public infrastructures and urban facilities in Malaysia in future. Eventually, this study opens an opportunity to improve Malaysian quality of life on the public value that created for the city as a whole.

Universitas Indonesia in cooperation with American Red Cross and Indonesian Red Cross have been assisting green open space revitalisation program in 7 locations in Bogor Regency (2016-2017). The program was held under The Urban Disaster Risk Reduction Greater Jakarta Project; an initiative program from American Red Cross Indonesia. This project was not only improving the existing green open space quality, but also creating one adapted from public land. The revitalization project figures what happened on daily basis on the existing land, proposing new programming facilities, community-based construction, monitoring and handing over. This paper discovers the meaning of a green space for the community, whether the community aware of its benefit on human health or environmental sustainability. The research question is does the community aware of green open space benefit for human health or environmental sustainability? Or both? The original data from the community was gathered and grouped based on its relevance with environmental quality and public health.

Urban Renewable Building And Neighborhood Optimization

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

URBANopt is a user interface for creating and running district and city scale building energy simulations. The framework is built around the OpenStudio Urban Measures which are part of the OpenStudio project. Building footprints, building height, building type, and other data can be imported from public records or other sources. Footprints and locations for new buildings and district systems can also be specified. OpenStudio Measures are used to create starting point energy models and to model energy design features and efficiency measures for each building. URBANopt allows a user to pose several scenarios such as “what if 30% of themore » commercial retail buildings added roof top solar” or “what if all elementary schools converted to ground source heat pumps” and then visualize the impacts at a district or city scale. URBANopt is capable of modeling existing buildings, new construction, and district energy systems. URBANopt can be used to explore options for achieving Zero Energy across a collection of buildings (e.g., Zero Energy Districts).« less

Human activities increasingly impact natural environments. Globally, many ecosystems are stressed to unhealthy limits, leading to loss of valuable ecosystem services- economic, ecologic and intrinsic. Virtual earths (virtual globes) (e.g., NASA World Wind, ossimPlanet, ArcGIS Explorer, Google Earth, Microsoft Virtual Earth) are geospatial data integration tools that can aid our efforts to understand and protect the environment. Virtual earths provide unprecedented desktop views of our planet, not only to professional scientists, but also to citizen scientists, students, environmental stewards, decision makers, urban developers and planners. Anyone with a broadband internet connection can explore the planet virtually, due in large part to freely available open source software and public domain imagery. This has at least two important potential benefits. One, individuals can study the planet from the visually intuitive perspective of the synoptic aerial view, promoting environmental awareness and stewardship. Two, it opens up the possibility of harnessing the in situ knowledge and observations of citizen scientists familiar with landscape conditions in their locales. Could this collective knowledge be harnessed (crowd sourcing) to validate and quality assure land cover and other maps? In this presentation we present examples using public domain imagery and two open source virtual earths to highlight some of the functionalities currently available. OssimPlanet is used to view aerial data from the USDA Geospatial Data Gateway. NASA World Wind is used to extract georeferenced high resolution USGS urban area orthoimagery. ArcGIS Explorer is used to demonstrate an example of image analysis using web processing services. The research presented here was conducted under the Environmental Feature Finder project of the Environmental Protection Agency's Advanced Monitoring Initiative.

Introducing Urban Food Forestry: A Multifunctional Strategy for Enhancing Urban Sustainability

NASA Astrophysics Data System (ADS)

Nicholas, K. A.; Clark, K.

2012-12-01

We propose combining elements of urban agriculture and urban forestry into what we call "urban food forestry" (UFF), the practice of growing perennial woody food-producing species ("food trees") in cities. We used four approaches at different scales to gauge the potential of UFF to enhance urban sustainability, in the context of trends including increasing urbanization, resource demands, and climate change. First, we analyzed 37 current international initiatives based around urban food trees, finding that core activities included planting, mapping, and harvesting food trees, but that only about a quarter of initiatives engaged in more than one of these activities necessary to fully utilize the food potential of urban trees. Second, we analyzed 30 urban forestry master plans, finding that only 13% included human food security among their objectives. Third, we used Burlington, Vermont as a case study to quantify the potential caloric output of publicly accessible open space if planted with Malus domestica (the common apple) under 9 different scenarios. We found that the entire caloric deficit of the very low food security population could be met on as few as 29 hectares (representing 16% of total open space), and that 98% of the daily recommended minimum intake of fruit for the entire city's population could be met under the most ambitious planting scenario. Finally, we developed a decision-making tool for selecting potential food trees appropriate for temperate urban environments, the Climate-Food-Species Matrix. We identified a total of 70 species, 30 of which we deemed "highly suitable" for urban food forestry based on their cold hardiness, drought tolerance, and edibility. We conclude that urban food forestry provides multiple pathways for building urban sustainability through local food production, and that our framework can be used to increase the coordination between and effectiveness of a growing number of related initiatives.

Public open space as the only urban space for walking: Sumatera Utara experience

One of successful public open space (POS) criteria is the proper pedestrian linkage. Furthermore, a good quality POS should pay attention to pedestrian activities. This will contribute to the physical and mental health of people and enhance their quality of life. The research means to investigate how POS accommodate the pedestrians. The study takes place in twenty small towns in Sumatra Utara province, Indonesia. The analysis is a descriptive, explorative study that collects data about physical elements of POS. The survey also uses a set of questionnaire to get information about the visitors walking tradition. The result of the study shows that most of the citizens approach and get to the POS by vehicle, both cars, and motorcycles. They use their private vehicles although the distance between their houses and the POS is less than one kilometer. There is no pedestrian linkage that connects the POS with the other part of urban space. However, the POS is active by various physical activities, such as walking, playing and exercising. These events occur both in pedestrian ways in the periphery, inside the POS, and in the other spots of the POS, such as grass field or multipurpose plaza. The visitors’ vehicle tradition relates to the whole urban space which is planned in a car-oriented way. Thus, the POS becomes the only space that people can walk and enjoy the environment.

Activating Public Space: How to Promote Physical Activity in Urban Environment

NASA Astrophysics Data System (ADS)

Kostrzewska, Małgorzata

Physical activity is an essential component of a healthy lifestyle. The quality and equipment of urban public space plays an important role in promoting physical activity among people (residents, tourists). In order for recreation and sports activities to be undertaken willingly, in a safe and comprehensive manner, certain spatial conditions and requirements must be met. The distinctive feature of contemporary large cities is the disappearance of local, neighbourly relations, and the consequent loneliness, alienation, and atomization of the residents. Thus, the design of public spaces should be an expression of the values of social inclusion and integration. A properly designed urban space would encourage people to leave their homes and integrate, also by undertaking different forms of physical activities. This, in turn, can lead to raising the quality of the space, especially in the context of its “familiarization” and “domestication”. The aim of the research was to identify the architectural and urban features of the public spaces of contemporary cities that can contribute to the promotion of physical activity. The paper presents the research results and the case studies of such spatial solutions and examples of good practices, which invite residents to undertake different forms of physical activities in public spaces. The issue of the integrating, inclusionary, and social function of physical recreation and sport is discussed as well, and so are the possibilities of translating these values into physical characteristics of an urban space. The main conclusions are that taking into account the diverse needs of different social groups, participation in the design and construction process, aesthetic and interesting design, vicinity of the residence, open access for all age groups and the disabled would be the most important spatial determinants of a properly designed, physically activating public space. Strategies of planning the sports and recreation infrastructure should also make sure of their multifunctionality and variability in time to adjust it to the changing needs of the residents.

Access to public open space is important to increase leisure-time walking (LTW) in high-income countries, but there is little evidence in middle-income countries. We conducted a cross-sectional analysis to examine the relationship between LTW and the presence of different public open spaces (parks, bike paths, and squares) and the mix of these recreational destinations near the homes of adults participating in the Sao Paulo Health Survey ( n = 3145). LTW was evaluated by a questionnaire. We delineated buffers (500, 1000, and 1500 m) from the geographic coordinates of the adults' residential addresses using a geographic information system. We used multilevel logistic regression taking account of clustering by census tracts and households, and with adjustment for social, demographics, and health characteristics. The main results showed that the presence of at least two recreational destinations within a 500-m buffer of participants' homes were associated with an increased odds of LTW compared with no destinations present (OR = 1.65; 95% CI 1.09-2.55). No associations were found for destinations further away. These results support actions outlined in the new urban plan for Sao Paulo city and could be used to highlight the importance access to a mix of public open spaces to promote physical activity in megacities of middle-income countries.

Mobile phone tracking: in support of modelling traffic-related air pollution contribution to individual exposure and its implications for public health impact assessment.

Liu, Hai-Ying; Skjetne, Erik; Kobernus, Mike

We propose a new approach to assess the impact of traffic-related air pollution on public health by mapping personal trajectories using mobile phone tracking technology in an urban environment. Although this approach is not based on any empirical studies, we believe that this method has great potential and deserves serious attention. Mobile phone tracking technology makes it feasible to generate millions of personal trajectories and thereby cover a large fraction of an urban population. Through analysis, personal trajectories are not only associated to persons, but it can also be associated with vehicles, vehicle type, vehicle speed, vehicle emission rates, and sources of vehicle emissions. Pollution levels can be estimated by dispersion models from calculated traffic emissions. Traffic pollution exposure to individuals can be estimated based on the exposure along the individual human trajectories in the estimated pollution concentration fields by utilizing modelling tools. By data integration, one may identify trajectory patterns of particularly exposed human groups. The approach of personal trajectories may open a new paradigm in understanding urban dynamics and new perspectives in population-wide empirical public health research. This new approach can be further applied to individual commuter route planning, land use planning, urban traffic network planning, and used by authorities to formulate air pollution mitigation policies and regulations.

Influence of urban morphology on total noise pollution: multifractal description.

PubMed

Ariza-Villaverde, Ana B; Jiménez-Hornero, Francisco J; Gutiérrez De Ravé, Eduardo

2014-02-15

Exposure to ambient noise levels above 65 dB can cause public health problems. The spatial distribution of this kind of pollution is linked to various elements which make up the urban form, such as construction density, the existence of open spaces and the shape and physical position of buildings. Since urban morphology displays multifractal behaviour, the present research studies for the first time the relationship between total noise pollution and urban features, such as street width and building height by means of a joint multifractal spectrum in two neighbourhoods of the city of Cordoba (Andalusia, Spain). According to the results, the joint multifractal spectrum reveals a positive correlation between the total noise pollution and the street width to building height ratio, this being more evident when urban morphology is regular. The information provided by the multifractal analysis completes the description obtained by using urban indexes and landscape metrics and might be useful for urban planning once the linkage between both frameworks has been done.

The Dublin Dashboard: Design and Development of a Real-Time Analytical Urban Dashboard

NASA Astrophysics Data System (ADS)

McArdle, G.; Kitchin, R.

2016-09-01

As many cities increase in size across multiple dimensions such as population, economic output and physical size, new methods for understanding and managing cities are required. Data produced by and about urban environments offer insight into what is happening in cities. Real-time data from sensors within the city record current transport and environmental conditions such as noise levels, water levels, journey times and public transport delays. Similarly administrative data such as demographics, employment statistics, property prices and crime rates all provide insight into how a city is evolving. Traditionally, these data were maintained separately and managed by individual city departments. Advances in technology and a move to open-government have placed many of these data in the public domain. Urban dashboards have emerged as a technique to visualise these data in an accessible way. This paper describes the implementation of one such dashboard, the Dublin Dashboard, an interactive website which collects, analyses and visualises data from a variety of sources about Dublin in Ireland through a series of interactive maps, graphs and applications. This paper describes the approach, the data and the technology used to develop the Dublin Dashboard and acts as a guideline for developing urban dashboards in other cities.

Catlett, Charlie; Malik, Tanu; Goldstein, Brett J.

2014-12-01

The past decade has seen the widespread release of open data concerning city services, conditions, and activities by government bodies and public institutions of all sizes. Hundreds of open data portals now host thousands of datasets of many different types. These new data sources represent enormous po- tential for improved understanding of urban dynamics and processes—and, ultimately, for more livable, efficient, and prosperous communities. However, those who seek to realize this potential quickly discover that discovering and applying those data relevant to any particular question can be extraordinarily dif- ficult, due to decentralized storage, heterogeneous formats, and poor documentation. Inmore » this context, we introduce Plenario, a platform designed to automating time-consuming tasks associated with the discovery, exploration, and application of open city data—and, in so doing, reduce barriers to data use for researchers, policymakers, service providers, journalists, and members of the general public. Key innovations include a geospatial data warehouse that allows data from many sources to be registered into a common spatial and temporal frame; simple and intuitive interfaces that permit rapid discovery and exploration of data subsets pertaining to a particular area and time, regardless of type and source; easy export of such data subsets for further analysis; a user-configurable data ingest framework for automated importing and periodic updating of new datasets into the data warehouse; cloud hosting for elastic scaling and rapid creation of new Plenario instances; and an open source implementation to enable community contributions. We describe here the architecture and implementation of the Plenario platform, discuss lessons learned from its use by several communities, and outline plans for future work.« less

Influence of Music on the Behaviors of Crowd in Urban Open Public Spaces

2018-01-01

Sound environment plays an important role in urban open spaces, yet studies on the effects of perception of the sound environment on crowd behaviors have been limited. The aim of this study, therefore, is to explore how music, which is considered an important soundscape element, affects crowd behaviors in urban open spaces. On-site observations were performed at a 100 m × 70 m urban leisure square in Harbin, China. Typical music was used to study the effects of perception of the sound environment on crowd behaviors; then, these behaviors were classified into movement (passing by and walking around) and non-movement behaviors (sitting). The results show that the path of passing by in an urban leisure square with music was more centralized than without music. Without music, 8.3% of people passing by walked near the edge of the square, whereas with music, this percentage was zero. In terms of the speed of passing by behavior, no significant difference was observed with the presence or absence of background music. Regarding the effect of music on walking around behavior in the square, the mean area and perimeter when background music was played were smaller than without background music. The mean speed of those exhibiting walking around behavior with background music in the square was 0.296 m/s slower than when no background music was played. For those exhibiting sitting behavior, when background music was not present, crowd density showed no variation based on the distance from the sound source. When music was present, it was observed that as the distance from the sound source increased, crowd density of those sitting behavior decreased accordingly. PMID:29755390

This paper explores three cases of Do-It-Yourself, open-source technologies developed within the diverse array of topics and themes in the communities around the Public Laboratory for Open Technology and Science (Public Lab). These cases focus on aerial mapping, water quality monitoring and civic science practices. The techniques discussed have in common the use of accessible, community-built technologies for acquiring data. They are also concerned with embedding collaborative and open source principles into the objects, tools, social formations and data sharing practices that emerge from these inquiries. The focus is on developing processes of collaborative design and experimentation through material engagement with technology and issues of concern. Problem-solving, here, is a tactic, while the strategy is an ongoing engagement with the problem of participation in its technological, social and political dimensions especially considering the increasing centralization and specialization of scientific and technological expertise. The authors also discuss and reflect on the Public Lab's approach to civic science in light of ideas and practices of citizen/civic veillance, or "sousveillance", by emphasizing people before data, and by investigating the new ways of seeing and doing that this shift in perspective might provide.

Significance of beach geomorphology on fecal indicator bacteria levels.

2017-08-15

Large databases of fecal indicator bacteria (FIB) measurements are available for coastal waters. With the assistance of satellite imagery, we illustrated the power of assessing data for many sites by evaluating beach features such as geomorphology, distance from rivers and canals, presence of piers and causeways, and degree of urbanization coupled with the enterococci FIB database for the state of Florida. We found that beach geomorphology was the primary characteristic associated with enterococci levels that exceeded regulatory guidelines. Beaches in close proximity to marshes or within bays had higher enterococci exceedances in comparison to open coast beaches. For open coast beaches, greater enterococci exceedances were associated with nearby rivers and higher levels of urbanization. Piers and causeways had a minimal contribution, as their effect was often overwhelmed by beach geomorphology. Results can be used to understand the potential causes of elevated enterococci levels and to promote public health. Copyright © 2017 Elsevier Ltd. All rights reserved.

Bawole, Paulus; Sutanto, Haryati B.

2017-11-01

Urban Kampong is a spontaneous settlement growing in several big cities within developing countries including Indonesia. This settlement is developed by low-income people without any plan. Therefore there is no specific housing pattern in the settlement. The characteristics of the settlements is dominated by Javanese traditional roof typology and narrow path with minimal public open spaces. People's creativity in building their houses often uses second hand building materials that make their houses look specific. Besides, infrastructure facilities within Kampong Settlement are very poor. Because the poor living in Urban Kampong have to adjust their live with minimum infrastructure facilities available, they have to be creative in using all facilities available. Through the creativities of low-income people living in Urban Kampong the research will show how the inhabitants can be empowered by exploring inhabitant's creativities and consequently the environmental quality within Urban Kampong can be improved as well.

The value of urban open space: meta-analyses of contingent valuation and hedonic pricing results.

PubMed

Brander, Luke M; Koetse, Mark J

2011-10-01

Urban open space provides a number of valuable services to urban populations, including recreational opportunities, aesthetic enjoyment, environmental functions, and may also be associated with existence values. In separate meta-analyses of the contingent valuation (CV) and hedonic pricing (HP) literature we examine which physical, socio-economic, and study characteristics determine the value of open space. The dependent variable in the CV meta-regression is defined as the value of open space per hectare per year in 2003 US$, and in the HP model as the percentage change in house price for a 10 m decrease in distance to open space. Using a multi-level modelling approach we find in both the CV and HP analyses that there is a positive and significant relationship between the value of urban open space and population density, indicating that scarcity and crowdedness matter, and that the value of open space does not vary significantly with income. Further, urban parks are more highly valued than other types of urban open space (forests, agricultural and undeveloped land) and methodological differences in study design have a large influence on estimated values from both CV and HP. We also find important regional differences in preferences for urban open space, which suggests that the potential for transferring estimated values between regions is likely to be limited.

Under the framework of developing resilient and livable cities, this study was aimed at engaging local communities to achieve the goal of public participation. Given the prevalence of smart mobile devices, an interactive app called “Citizen Probe” was designed to guide users to participate in building resilient and livable urban spaces by enabling users to report the condition of their living environment. The app collects feedback from users regarding the perceived condition of the urban environment, and this information is used to further develop an open online index system. The index system serves as a guide for the public to actively transform their city into a resilient and livable urban environment. The app was designed for the reporting of flood incidents with the objective of resilient disaster prevention, which can be achieved by enabling users to identify disaster conditions in order to develop a database for basic disaster information. The database can be used in the prevention and mitigation of disasters and to provide a foundation for developing indices for assessing the resilience and livability of urban areas. Three communities in Taichung, Taiwan, participated in the study. Residents of these communities were requested to use the app and identify local environmental conditions to obtain spatial data according to four stages in disaster response: assessment, readiness, response, and recovery. A volunteered geographic information database was developed to display maps for providing users with current reports of predisaster risk assessment, disaster response capacity, real-time disaster conditions, and overall disaster recovery. In addition, the database can be used as a useful tool for researchers to conduct GIS analyses and initiate related discussions. The interactive app raises public awareness on disaster prevention and makes disaster prevention a daily norm. Further discussion between the public and experts will be initiated to assist in policy management pertaining to the ongoing development of cities in addition to improving disaster prevention and response measures.

Urbanization, regime type and durability, and environmental degradation in Ghana.

2016-12-01

This study examines the effect of urbanization, income, trade openness, and institutional quality (i.e., regime type and durability) on environmental degradation in Ghana over the period 1965-2011. Using the bounds test approach to cointegration and the Fully Modified Phillip-Hansen (FMPH) technique, the findings show that urbanization, income, trade openness, and institutional quality have long-run cointegration with environmental degradation. Further, the results show that income, trade openness, and institutional quality are negatively associated with environmental degradation. This suggests that income, trade openness, and institutional quality enhance environmental performance. Urbanization, however, is positively related to environmental degradation. Additionally, long-run estimates conditioned on institutional quality reveal that the extent to which trade openness and urbanization enhance environmental performance is largely due to the presence of quality institutions (or democratic institutions). Finally, controlling for structural breaks, we find that trade openness, urbanization, and regime type (i.e., democracy) improve environmental performance significantly after the 1970s except for income.

Urban Boundary Extraction and Urban Sprawl Measurement Using High-Resolution Remote Sensing Images: a Case Study of China's Provincial

Urban boundary is an important indicator for urban sprawl analysis. However, methods of urban boundary extraction were inconsistent, and construction land or urban impervious surfaces was usually used to represent urban areas with coarse-resolution images, resulting in lower precision and incomparable urban boundary products. To solve above problems, a semi-automatic method of urban boundary extraction was proposed by using high-resolution image and geographic information data. Urban landscape and form characteristics, geographical knowledge were combined to generate a series of standardized rules for urban boundary extraction. Urban boundaries of China's 31 provincial capitals in year 2000, 2005, 2010 and 2015 were extracted with above-mentioned method. Compared with other two open urban boundary products, accuracy of urban boundary in this study was the highest. Urban boundary, together with other thematic data, were integrated to measure and analyse urban sprawl. Results showed that China's provincial capitals had undergone a rapid urbanization from year 2000 to 2015, with the area change from 6520 square kilometres to 12398 square kilometres. Urban area of provincial capital had a remarkable region difference and a high degree of concentration. Urban land became more intensive in general. Urban sprawl rate showed inharmonious with population growth rate. About sixty percent of the new urban areas came from cultivated land. The paper provided a consistent method of urban boundary extraction and urban sprawl measurement using high-resolution remote sensing images. The result of urban sprawl of China's provincial capital provided valuable urbanization information for government and public.

Shade in public spaces can lower the risk of and sun burning and skin cancer. However, existing methods of auditing shade require travel between sites, and sunny weather conditions. This study aimed to evaluate the feasibility of free computer software-Google Earth-for assessing shade in urban open spaces. A shade projection method was developed that uses Google Earth street view and aerial images to estimate shade at solar noon on the summer solstice, irrespective of the date of image capture. Three researchers used the method to separately estimate shade cover over pre-defined activity areas in a sample of 45 New Zealand urban open spaces, including 24 playgrounds, 12 beaches and 9 outdoor pools. Outcome measures included method accuracy (assessed by comparison with a subsample of field observations of 10 of the settings) and inter-rater reliability. Of the 164 activity areas identified in the 45 settings, most (83%) had no shade cover. The method identified most activity areas in playgrounds (85%) and beaches (93%) and was accurate for assessing shade over these areas (predictive values of 100%). Only 8% of activity areas at outdoor pools were identified, due to a lack of street view images. Reliability for shade cover estimates was excellent (intraclass correlation coefficient of 0.97, 95% CI 0.97-0.98). Google Earth appears to be a reasonably accurate and reliable and shade audit tool for playgrounds and beaches. The findings are relevant for programmes focused on supporting the development of healthy urban open spaces.

Neighbourhood-open space relationships in metropolitan planning: a look across four scales of concern

New Urbanism and other metropolitan planning strategies may discount the importance of neighbourhood-open space relationships when dealing with some types of open spaces, particularly in city centre and urban fringe areas. In this paper I review a series of studies I have carried out over the past decade looking at people's perceptions and uses of urban open space...

Personal benefits of public open space: a case study in Boston's Arnold Arboretum

Managers of urban parks need to document the benefits that their parks produce. Use level is a typical measure of such benefits, but simple use statistics can mask the rich diversity of people and activities that the parks serve. This study examined the uses and users of Boston's Arnold Arboretum during late summer in 1992. On 25 sample days, we recorded...

Pedestrian-friendly neighborhoods with proximal destinations and services encourage walking and decrease car dependence, thereby contributing to more active and healthier communities. Proximity to key destinations and services is an important aspect of the urban design decision making process, particularly in areas adopting a transit-oriented development (TOD) approach to urban planning, whereby densification occurs within walking distance of transit nodes. Modeling destination access within neighborhoods has been limited to circular catchment buffers or more sophisticated network-buffers generated using geoprocessing routines within geographical information systems (GIS). Both circular and network-buffer catchment methods are problematic. Circular catchment models do not account for street networks, thus do not allow exploratory 'what-if' scenario modeling; and network-buffering functionality typically exists within proprietary GIS software, which can be costly and requires a high level of expertise to operate. This study sought to overcome these limitations by developing an open-source simple agent-based walkable catchment tool that can be used by researchers, urban designers, planners, and policy makers to test scenarios for improving neighborhood walkable catchments. A simplified version of an agent-based model was ported to a vector-based open source GIS web tool using data derived from the Australian Urban Research Infrastructure Network (AURIN). The tool was developed and tested with end-user stakeholder working group input. The resulting model has proven to be effective and flexible, allowing stakeholders to assess and optimize the walkability of neighborhood catchments around actual or potential nodes of interest (e.g., schools, public transport stops). Users can derive a range of metrics to compare different scenarios modeled. These include: catchment area versus circular buffer ratios; mean number of streets crossed; and modeling of different walking speeds and wait time at intersections. The tool has the capacity to influence planning and public health advocacy and practice, and by using open-access source software, it is available for use locally and internationally. There is also scope to extend this version of the tool from a simple to a complex model, which includes agents (i.e., simulated pedestrians) 'learning' and incorporating other environmental attributes that enhance walkability (e.g., residential density, mixed land use, traffic volume).

Health impact assessment on urban development projects in France: finding pathways to fit practice to context.

PubMed

Roué-Le Gall, Anne; Jabot, Françoise

In France, there is increasing interest in health impact assessments (HIAs) and most are performed on urban projects. The field of expertise is still under development and mostly established within the public health sector. To date, in France, all HIAs conducted in urban planning are stand-alone HIAs disconnected from the required environmental impact assessment (EIA). The paper opens with an introduction of the close and complex relationship between health and urban planning, HIA and a description of key elements needed for understanding the French context. Then, the paper analyses the context and the implementation process for four HIAs in progress in order to understand the specific characteristics of urban development, identify the key stages for introducing a health perspective into urban projects, and extract avenues to be explored when adapting HIAs applied to urban planning in France. Using a qualitative multiple case study design, an analysis framework was built to compare several aspects of the four HIAs and made it possible to highlight three pathways for adapting HIA to the urban planning sector: the schedule, links between the EIA and HIA, and the complementarity of the initiatives to involve residents. Legal measures enable a point of contact that brings health institutions and cities closer together. HIA is yet another tool that public authorities now have at their fingertips to work together in strengthening democracy and in reducing social, geographical and environmental health inequalities. More research must be undertaken to develop an understanding of the practice-related context; to judge HIA's capacity to draw on existing approaches in different fields; and to explore the different avenues leading to increased health, wellbeing and equity.

Rethinking urban space in cities - A study of parks in Hyderabad, India

Shrinagesh, B.; Markandey, Kalpana

2016-06-01

Urban areas being economically diversified attract large streams of migrants making for a burgeoning population. This is more prevalent in the developing countries. The concomitants of this are high density, heavy traffic movement and increased pollution levels. To reduce the stressful life of city dwellers it is important to have open spaces, where one can pursue leisure time activities a few removes from clutter. A public space is a space that is generally open and accessible to people. Roads, public parks, libraries etc, are typically considered public space. The term ‘public space’ is also often misconstrued to mean other things such as ‘gathering place’, which is an element of the larger concept of social space. Hyderabad, the historical city is the capital of Telangana, India and extends from longitude 78o23’ to 78o33’E and latitude of 17o17’ to 17o31’N. It is the second largest city in terms of area and fifth largest in terms of population. It is one of the fastest growing cities in India. There is a huge influx of people from other states in search of better opportunities. The main objectives of the study are; to study the sprawl and changing demographic structure of the city of Hyderabad, to study the accessibility of parks, to study the need for the emergence of a local public sphere. The data base will be mainly on secondary data collected from various government sources. A primary survey will be conducted based on a structured questionnaire. GIS and other mapping techniques will be applied to analyse the data.

The meaning of city noises: Investigating sound quality in Paris (France)

Dubois, Daniele; Guastavino, Catherine; Maffiolo, Valerie; Guastavino, Catherine; Maffiolo, Valerie

2004-05-01

The sound quality of Paris (France) was investigated by using field inquiries in actual environments (open questionnaires) and using recordings under laboratory conditions (free-sorting tasks). Cognitive categories of soundscapes were inferred by means of psycholinguistic analyses of verbal data and of mathematical analyses of similarity judgments. Results show that auditory judgments mainly rely on source identification. The appraisal of urban noise therefore depends on the qualitative evaluation of noise sources. The salience of human sounds in public spaces has been demonstrated, in relation to pleasantness judgments: soundscapes with human presence tend to be perceived as more pleasant than soundscapes consisting solely of mechanical sounds. Furthermore, human sounds are qualitatively processed as indicators of human outdoor activities, such as open markets, pedestrian areas, and sidewalk cafe districts that reflect city life. In contrast, mechanical noises (mainly traffic noise) are commonly described in terms of physical properties (temporal structure, intensity) of a permanent background noise that also characterizes urban areas. This connotes considering both quantitative and qualitative descriptions to account for the diversity of cognitive interpretations of urban soundscapes, since subjective evaluations depend both on the meaning attributed to noise sources and on inherent properties of the acoustic signal.

Plenario: A Spatio-Temporal Platform for Discovery and Exploration of Urban Science Data

Engler, W. H.; Malik, T.; Catlett, C.; Foster, I.; Goldstein, B.

2015-12-01

The past decade has seen the widespread release of open data concerning city services, conditions, and activities by government bodies and public institutions of all sizes. Hundreds of open data portals now host thousands of datasets of many different types. These new data sources represent enormous potential for improved understanding of urban dynamics and processes—and, ultimately, for more livable, efficient, and prosperous communities. However, those who seek to realize this potential quickly discover that discovering and applying those data relevant to any particular question can be extraordinarily difficult, due to decentralized storage, heterogeneous formats, and poor documentation. In this context, we introduce Plenario, a platform designed to automating time-consuming tasks associated with the discovery, exploration, and application of open city data—and, in so doing, reduce barriers to data use for researchers, policymakers, service providers, journalists, and members of the general public. Key innovations include a geospatial data warehouse that allows data from many sources to be registered into a common spatial and temporal frame; simple and intuitive interfaces that permit rapid discovery and exploration of data subsets pertaining to a particular area and time, regardless of type and source; easy export of such data subsets for further analysis; a user-configurable data ingest framework for automated importing and periodic updating of new datasets into the data warehouse; cloud hosting for elastic scaling and rapid creation of new Plenario instances; and an open source implementation to enable community contributions. We describe here the architecture and implementation of the Plenario platform, discuss lessons learned from its use by several communities, and outline plans for future work.

Sustainable urban design is an effective way to improve urban ventilation and reduce vehicular pollutant exposure to urban residents. This paper investigated the impacts of urban open space and 'lift-up' building design on vehicular CO (carbon monoxide) exposure in typical three-dimensional (3D) urban canopy layer (UCL) models under neutral atmospheric conditions. The building intake fraction (IF) represents the fraction of total vehicular pollutant emissions inhaled by residents when they stay at home. The building daily CO exposure (E t ) means the extent of human beings' contact with CO within one day indoor at home. Computational fluid dynamics (CFD) simulations integrating with these two concepts were performed to solve turbulent flow and assess vehicular CO exposure to urban residents. CFD technique with the standard k-ε model was successfully validated by wind tunnel data. The initial numerical UCL model consists of 5-row and 5-column (5×5) cubic buildings (building height H=street width W=30m) with four approaching wind directions (θ=0°, 15°, 30°, 45°). In Group I, one of the 25 building models is removed to attain urban open space settings. In Group II, the first floor (Lift-up1), or second floor (Lift-up2), or third floor (Lift-up3) of all buildings is elevated respectively to create wind pathways through buildings. Compared to the initial case, urban open space can slightly or significantly reduce pollutant exposure for urban residents. As θ=30° and 45°, open space settings are more effective to reduce pollutant exposure than θ=0° and 15°.The pollutant dilution near or surrounding open space and in its adjacent downstream regions is usually enhanced. Lift-up1 and Lift-up2 experience much greater pollutant exposure reduction in all wind directions than Lift-up3 and open space. Although further investigations are still required to provide practical guidelines, this study is one of the first attempts for reducing urban pollutant exposure by improving urban design.

Science literate and engaged members of the public, including students, are critical to building climate resilient communities. USC Sea Grant facilitates programs that work to build and strengthen these connections. The Urban Tides Community Science Initiative (Urban Tides) and the Youth Exploring Sea Level Rise Science Program (YESS) engage communities across the boundaries of public engagement, K-12 education, and informal education. YESS is an experiential sea level rise education program that combines classroom learning, field investigations and public presentations. Students explore sea level rise using a new curricula, collect their own data on sea level rise, develop communication products, and present their findings to city governments, researchers, and others. Urban Tides engages community members, informal education centers, K-12 students, and local government leaders in a citizen science program photo- documenting extreme high tides, erosion and coastal flooding in Southern California. Images provide critical information to help calibrate scientific models used to identify locations vulnerable to damage from future sea level rise. These tools and information enable community leaders and local governments to set priorities, guidelines, and update policies as they plan strategies that will help the region adapt. The program includes a mobile app for data collection, an open database to view photos, a lesson plan, and community beach walks. Urban Tides has led to an increase in data and data-gathering capacity for regional scientists, an increase in public participation in science, and an increase in ocean and climate literacy among initiative participants. Both of these programs bring informed and diverse voices into the discussion of how to adapt and build climate resilient communities. USC Sea Grant will share impacts and lessons learned from these two unique programs.

The common trend of urban population has been growing significantly in Indonesia for decades, are affected by urban green space conversion. Generally, this area is utilized for urban infrastructures and residences. Furthermore, urban area has grown uncontrollably that could enhance the phenomenon of urban sprawl. The conversion of green urban area and agricultural area will significantly decrease urban food security and quality of urban environment. This problem becomes a serious issue for urban sustainability. Bandung is a city with dense population where there are many poor inhabitants. Families living in poverty are subjected to food insecurity caused by the rise of food prices. Based on the urgency of urban food security and urban environment quality the local government has to achieve comprehensive solutions. This research aims to formulate the policy of productive green open space towards food security for poor people in Bandung. This research not only examines the role played by productive green open space to supply food for the urban poor but also how to govern urban areas sustainably and ensure food security. This research uses descriptive explanatory methodology that describes and explains how to generate policy and strategic planning for edible landscape to promote urban food security. Taman Sari is the location of this research, this area is a populous area that has amount of poor people and has a quite worse quality of urban environment. This study shows that urban green open space has the potential to be utilized as an urban farming land, which poor inhabitants could be main actors to manage urban agriculture to provide their food. Meanwhile, local government could contribute to subsidize the financial of urban farming activities.

Regional Assessment of Urban Impacts on Landcover and Open Space Finds a Smart Urban Growth Policy Performs Little Better than Business as Usual

Assessment of landscape change is critical for attainment of regional sustainability goals. Urban growth assessments are needed because over half the global population now lives in cities, which impact biodiversity, ecosystem structure and ecological processes. Open space protection is needed to preserve these attributes, and provide the resources humans need. The San Francisco Bay Area, California, is challenged to accommodate a population increase of 3.07 million while maintaining the region’s ecosystems and biodiversity. Our analysis of 9275 km2 in the Bay Area links historic trends for three measures: urban growth, protected open space, and landcover types over the last 70 years to future 2050 projections of urban growth and open space. Protected open space totaled 348 km2 (3.7% of the area) in 1940, and expanded to 2221 km2 (20.2%) currently. An additional 1038 km2 of protected open space is targeted (35.1%). Urban area historically increased from 396.5 km2 to 2239 km2 (24.1% of the area). Urban growth during this time mostly occurred at the expense of agricultural landscapes (62.9%) rather than natural vegetation. Smart Growth development has been advanced as a preferred alternative in many planning circles, but we found that it conserved only marginally more open space than Business-as-usual when using an urban growth model to portray policies for future urban growth. Scenarios to 2050 suggest urban development on non-urban lands of 1091, 956, or 179 km2, under Business-as-usual, Smart Growth and Infill policy growth scenarios, respectively. The Smart Growth policy converts 88% of natural lands and agriculture used by Business-as-usual, while Infill used only 40% of those lands. Given the historic rate of urban growth, 0.25%/year, and limited space available, the Infill scenario is recommended. While the data may differ, the use of an historic and future framework to track these three variables can be easily applied to other metropolitan areas. PMID:23755204

Although health disparities research has already contributed to decreased mortality and morbidity in underserved communities, more work is needed. The NYC Epi Scholars program of the New York City Department of Health and Mental Hygiene (NYC DOHMH) aims to address gaps in critical public health needs and to train future public health leaders in epidemiology. The program is designed to increase racial/ethnic and socioeconomic diversity in the public health workforce, to provide fieldwork and practica opportunities, and to cultivate future leaders in epidemiology and public health. Since its inception in 2007, the NYC Epi Scholars program of the NYC DOHMH has sought talented epidemiology students interested in gaining practical experience in applied health disparities research. NYC Epi Scholars is open to graduate epidemiology students who have demonstrated achievement and leadership potential and gives them an opportunity to provide high-quality research assistance to projects that identify and address health disparities of public health significance. Many of the program's 32 alumni have made notable contributions to public health: publishing articles in peer-reviewed journals; making presentations at national and international conferences; and after graduating, pursuing careers at the DOHMH, Centers for Disease Control and Prevention, the Environmental Protection Agency, and the National Institutes of Health. Because of its noted success, the NYC Epi Scholars program may serve as a "best-practice" model for expansion in other urban health departments.

The Western Earth Surface Processes Team (WESPT) of the U.S. Geological Survey (USGS) conducts geologic mapping and related topical earth-science studies in the Western United States. This work is focused on areas where modern geologic maps and associated earth-science data are needed to address key societal and environmental issues, such as ground-water quality, landslides and other potential geologic hazards, and land-use decisions. Areas of primary emphasis in 2001 included southern California, the San Francisco Bay region, the Pacific Northwest, and the Las Vegas urban corridor. The team has its headquarters in Menlo Park, California, and maintains smaller field offices at several other locations in the Western United States. The results of research conducted by the WESPT are released to the public as a variety of databases, maps, text reports, and abstracts, both through the internal publication system of the USGS and in diverse external publications such as scientific journals and books. This report lists publications of the WESPT released in 2001, as well as additional 1999 and 2000 publications that were not included in the previous list (USGS Open-File Report 00–215 and USGS Open-File Report 01–198). Most of the publications listed were authored or coauthored by WESPT staff. The list also includes some publications authored by non-USGS cooperators with the WESPT, as well as some authored by USGS staff outside the WESPT in cooperation with WESPT projects. Several of the publications listed are available on the World Wide Web; for these, URL addresses are provided. Many of these web publications are USGS Open-File Reports that contain large digital databases of geologic map and related information.

[Changes in urban development: is the globalization era one of urban deconcentration?].

PubMed

Rivera, S

1997-01-01

Urbanization patterns in Mexico during the past five decades clearly reflect trends in the country's capitalist development. Accelerated industrialization with protectionism; redistributive policies with unlimited expansion of public expenditures; industrial conversion attended by economic crisis and structural adjustment during the "lost decade" of the 1980s; and indiscriminate opening, currency instability, and anti-inflation measures in the stage of globalization represent four successive phases. This work argues that the commercial opening and application of a neoliberal model are likely to renew tendencies toward concentration of population and economic activity in a few metropolitan areas. There are indications that manufacturing is again tending to concentrate in the older industrial cities, especially Mexico City. The 1995 census suggests that, beginning in 1988, the metropolitan areas again began to attract population growth, after a cycle of outflow from the center city to the metropolitan periphery in the 1970s and 1980s. The trend toward deconcentration, thus, may not represent a linear and long-term tendency. Instead, fluctuations over time are intimately related to macroeconomic forces and regulatory mechanisms that influence the urban system. No consensus has been reached concerning the theoretical explanations of effects on regional or urban systems when international restrictions on commerce are eliminated. The neoclassical perspective predicts a homogenizing effect, assuming that key conditions are met, while a competing theory predicts that increasing competition will inevitably be met by increases in the scale of production. Incentives to focus production in a small number of places would lead to economic and demographic concentration in the urban centers or regions enjoying better infrastructure, more qualified labor forces, and more extensive markets for labor and consumption. A renewed cycle of locus in Mexico's largest metropolitan zones may currently be underway.

Spatial analysis related to the location characteristics of park supply. Case study: Music Park and Pendawa Park, Bandung City, Indonesia

Public space plays a role in defining the character of a city and is a valuable asset for a city and one of the indicators in assessing whether a city is considered successful or not. In the context of urban sociology, high-quality public spaces with well-maintained environments can improve the quality of the heterogeneous life of urban social communities by creating economic, social, or environmental value-added. Urban societies tend to be heterogeneous, individualistic, and characterized by high competition that often causes conflicts. Another reason for conflicts is the relatively high social differentiation because of the level of religious differences, customs, languages, and sociocultural aspects brought by immigrants from various regions. In the context of space, the city is a system that does not stand alone because internally the city is a unified system of functional activities in it. Meanwhile, externally, the city is influenced by its surrounding environment. As part of the public space, park has an important role in the environmental, aesthetic, recreational, psychological, social, educational, and economic aspects of the city. Public space can be understood as open spaces in urban areas, where everyone regardless their interests and backgrounds can be intersectional and have social contact and serve as an “urban regenerator” including educational functions through innovation and technological intervention. Moreover, park can also absorb carbon dioxide emissions, produce oxygen, improve air and water quality, regulate the microclimate, reduce noise, protect soil and water, and maintain biodiversity. However, many things cause the function of parks to decrease. One reason relates to the distribution of parks related to the characteristics of their location. Research has not seen many studies on the characteristics of locations in the planning of public space. The provision of public space should consider these location characteristics. This study will use a descriptive methodology, by first explaining the policy of public space provision, the existence of the reality of public space, its function and role, the park as public space, the time of visiting the park by the community, and the various problems that occur in it. This research will look at the characteristics of neighborhood parks based on the aspect of the location of park supply and the spatial policies of Bandung City. The analysis comprised ArcGIS (Geographic Information System) and direct observations to evaluate the locational characteristics of the area around the park by using the case study of Music Park and Pendawa Park.

Development and Evaluation of the Brief Sexual Openness Scale—A Construal Level Theory Based Approach

2015-01-01

Obtaining reliable and valid data on sensitive questions represents a longstanding challenge for public health, particularly HIV research. To overcome the challenge, we assessed a construal level theory (CLT)-based novel method. The method was previously established and pilot-tested using the Brief Sexual Openness Scale (BSOS). This scale consists of five items assessing attitudes toward premarital sex, multiple sexual partners, homosexuality, extramarital sex, and commercial sex, all rated on a standard 5-point Likert scale. In addition to self-assessment, the participants were asked to assess rural residents, urban residents, and foreigners. The self-assessment plus the assessment of the three other groups were all used as subconstructs of one latent construct: sexual openness. The method was validated with data from 1,132 rural-to-urban migrants (mean age = 32.5, SD = 7.9; 49.6% female) recruited in China. Consistent with CLT, the Cronbach alpha of the BSOS as a conventional tool increased with social distance, from .81 for self-assessment to .97 for assessing foreigners. In addition to a satisfactory fit of the data to a one-factor model (CFI = .94, TLI = .93, RMSEA = .08), a common factor was separated from the four perspective factors (i.e., migrants’ self-perspective and their perspectives of rural residents, urban residents and foreigners) through a trifactor modeling analysis (CFI = .95, TLI = .94, RMSEA = .08). Relative to its conventional form, CTL-based BSOS was more reliable (alpha: .96 vs .81) and valid in predicting sexual desire, frequency of dating, age of first sex, multiple sexual partners and STD history. This novel technique can be used to assess sexual openness, and possibly other sensitive questions among Chinese domestic migrants. PMID:26308336

Staff turnover rates in publicly-funded mental health settings are high. We investigated staff and organizational predictors of turnover in a sample of individuals working in an urban public mental health system that has engaged in a system-level effort to implement evidence-based practices. Additionally, we interviewed staff to understand reasons for turnover. Greater staff burnout predicted increased turnover, more openness toward new practices predicted retention, and more professional recognition predicted increased turnover. Staff reported leaving their organizations because of personal, organizational, and financial reasons; just over half of staff that left their organization stayed in the public mental health sector. Implications include an imperative to focus on turnover, with a particular emphasis on ameliorating staff burnout.

Proponents of urban agriculture have identified its potential to improve health and the environment but in New York City and other densely developed and populated urban areas, it faces huge challenges because of the shortage of space, cost of land, and the lack of contemporary local food production. However, large portions of the city and metropolitan region do have open land and a history of agricultural production in the not-too-distant past. Local food movements and concerns about food security have sparked a growing interest in urban farming. Policies in other sectors to address diet-related illnesses, environmental quality and climate change may also provide opportunities to expand urban farming. Nevertheless, for any major advances in urban agriculture, significant changes in local and regional land use policies are needed. These do not appear to be forthcoming any time soon unless food movements amplify their voices in local and national food policy. Based on his experiences as founder of a small farm in Brooklyn, New York and his engagement with local food movements, the author analyzes obstacles and opportunities for expanding urban agriculture in New York.

Environment-health research has shown significant relationships between the quantity of green space in deprived urban neighbourhoods and people's stress levels. The focus of this paper is the nature of access to green space (i.e., its quantity or use) necessary before any health benefit is found. It draws on a cross-sectional survey of 406 adults in four communities of high urban deprivation in Scotland, United Kingdom. Self-reported measures of stress and general health were primary outcomes; physical activity and social wellbeing were also measured. A comprehensive, objective measure of green space quantity around each participant's home was also used, alongside self-report measures of use of local green space. Correlated Component Regression identified the optimal predictors for primary outcome variables in the different communities surveyed. Social isolation and place belonging were the strongest predictors of stress in three out of four communities sampled, and of poor general health in the fourth, least healthy, community. The amount of green space in the neighbourhood, and in particular access to a garden or allotment, were significant predictors of stress. Physical activity, frequency of visits to green space in winter months, and views from the home were predictors of general health. The findings have implications for public health and for planning of green infrastructure, gardens and public open space in urban environments.

Urban Flow and Pollutant Dispersion Simulation with Multi-scale coupling of Meteorological Model with Computational Fluid Dynamic Analysis

NASA Astrophysics Data System (ADS)

Liu, Yushi; Poh, Hee Joo

2014-11-01

The Computational Fluid Dynamics analysis has become increasingly important in modern urban planning in order to create highly livable city. This paper presents a multi-scale modeling methodology which couples Weather Research and Forecasting (WRF) Model with open source CFD simulation tool, OpenFOAM. This coupling enables the simulation of the wind flow and pollutant dispersion in urban built-up area with high resolution mesh. In this methodology meso-scale model WRF provides the boundary condition for the micro-scale CFD model OpenFOAM. The advantage is that the realistic weather condition is taken into account in the CFD simulation and complexity of building layout can be handled with ease by meshing utility of OpenFOAM. The result is validated against the Joint Urban 2003 Tracer Field Tests in Oklahoma City and there is reasonably good agreement between the CFD simulation and field observation. The coupling of WRF- OpenFOAM provide urban planners with reliable environmental modeling tool in actual urban built-up area; and it can be further extended with consideration of future weather conditions for the scenario studies on climate change impact.

2014-10-01

The global burden of disease study estimated 695,000 premature deaths in 2010 due to continued exposure to outdoor particulate matter and ozone pollution for India. By 2030, the expected growth in many of the sectors (industries, residential, transportation, power generation, and construction) will result in an increase in pollution related health impacts for most cities. The available information on urban air pollution, their sources, and the potential of various interventions to control pollution, should help us propose a cleaner path to 2030. In this paper, we present an overview of the emission sources and control options for better air quality in Indian cities, with a particular focus on interventions like urban public transportation facilities; travel demand management; emission regulations for power plants; clean technology for brick kilns; management of road dust; and waste management to control open waste burning. Also included is a broader discussion on key institutional measures, like public awareness and scientific studies, necessary for building an effective air quality management plan in Indian cities.

Water as a coolant of the city

2014-05-01

Rapid urbanization during the last century showed the necessity for understanding urban climate. Since already half of the world population lives in cities - and this number is predicted to increase in coming years and decades - making big urban areas comfortable places gains interest of the general public and policy makers, as well as scientists. It is well known fact that urban climate differs significantly from the climate of rural areas. This is caused by several factors such as lack of evaporation, anthropogenic heat, specific geometry of street canyons, etc. Magnitude of the effect of each of these factors is a widely discussed topic throughout the literature. One of the most important factors is a lack of evaporation and consequent change in the energy balance compared to rural areas. This research aims to reveal the effect of water in the city on the temperature and comfort of inhabitants. We hypothesize that water works as a cooling liquid of cities and the lack of it is the main reason for formation of so called urban heat island. We focus on two major ways water can be stored in cities; in a form of open water areas, and in plants and green areas in general. Open water buffers the temperature extremes in its surroundings, but also has a warming effect at night due to its higher heat capacity compared to buildings and pavements. Trees are then providing shading and transpirate significant amount of water. On the other hand, shading effect alone, as provided by for example mash, can increase the temperature in the area simply because it prevents ventilation. Human comfort is however not determined only by temperature; for example higher air humidity is known to lower comfort of inhabitants and therefore mitigate the cooling effect of evaporation. Understanding properly the different effects of urban climate, and the particular aspects that can influence it, is important for optimal urban design that provides pleasant living environment.

Using simple agent-based modeling to inform and enhance neighborhood walkability

PubMed Central

2013-01-01

Background Pedestrian-friendly neighborhoods with proximal destinations and services encourage walking and decrease car dependence, thereby contributing to more active and healthier communities. Proximity to key destinations and services is an important aspect of the urban design decision making process, particularly in areas adopting a transit-oriented development (TOD) approach to urban planning, whereby densification occurs within walking distance of transit nodes. Modeling destination access within neighborhoods has been limited to circular catchment buffers or more sophisticated network-buffers generated using geoprocessing routines within geographical information systems (GIS). Both circular and network-buffer catchment methods are problematic. Circular catchment models do not account for street networks, thus do not allow exploratory ‘what-if’ scenario modeling; and network-buffering functionality typically exists within proprietary GIS software, which can be costly and requires a high level of expertise to operate. Methods This study sought to overcome these limitations by developing an open-source simple agent-based walkable catchment tool that can be used by researchers, urban designers, planners, and policy makers to test scenarios for improving neighborhood walkable catchments. A simplified version of an agent-based model was ported to a vector-based open source GIS web tool using data derived from the Australian Urban Research Infrastructure Network (AURIN). The tool was developed and tested with end-user stakeholder working group input. Results The resulting model has proven to be effective and flexible, allowing stakeholders to assess and optimize the walkability of neighborhood catchments around actual or potential nodes of interest (e.g., schools, public transport stops). Users can derive a range of metrics to compare different scenarios modeled. These include: catchment area versus circular buffer ratios; mean number of streets crossed; and modeling of different walking speeds and wait time at intersections. Conclusions The tool has the capacity to influence planning and public health advocacy and practice, and by using open-access source software, it is available for use locally and internationally. There is also scope to extend this version of the tool from a simple to a complex model, which includes agents (i.e., simulated pedestrians) ‘learning’ and incorporating other environmental attributes that enhance walkability (e.g., residential density, mixed land use, traffic volume).

PHARMACY, MONEY AND PUBLIC HEALTH IN DAKAR.

Tousignant, Noémi

2013-11-01

Pharmacy students at the Cheikh Anta Diop University in Dakar must research and write a thesis to graduate. Thésards who took topics in analytical chemistry and toxicology describe their thesis work as a temporary opportunity to perform 'street-level' public health research that they regard as 'relevant' to the quality of people's lives. Expecting futures in the private commercial sector, thésards regretfully leave the thesis behind. This article explores the parenthetical nature of this moment - its brief openings and more durable closures - as part of the history of ways of being a pharmacist in post-colonial Senegal. The thesis as an interlude in students' biographies, curtailed by narrowed horizons of expectation, evokes other contractions: in the range of professional roles open to Senegalese pharmacists, and in the circuits of public health with which they might engage. For thésards, fieldwork, government work and commercial work entail spatial practices and imaginations; different ways of moving around the city and of tracing urban space that define pharmacists' roles in terms of the modes through which they engage with broader collectivities. Mapping thésards' parenthesis in Dakar is a means of capturing both their urban experience of work and the intertwining spatial, temporal and affective dimensions associated with this work. The past, probable and possible trajectories of pharmacy work are imprinted and imagined in the space of the city as field, market and polis. Pharmacists' prospects and aspirations are caught up in broader shifts in how education, (un)employment and entrepreneurship animate relations of association and exchange in Senegal.

Hedges are both ecologically and culturally important and are a distinctive feature of the British landscape. However the overall length of hedges across Great Britain is decreasing. Current challenges in studying hedges relate to the dominance of research on rural, as opposed to urban, hedges, and their variability and geographical breadth. To help address these challenges and to educate the public on the importance of hedge habitats for wildlife, in 2010 the Open Air Laboratories (OPAL) programme coordinated a hedge-focused citizen science survey. Results from 2891 surveys were analysed. Woody plant species differed significantly between urban and rural areas. Beech, Holly, Ivy, Laurel, Privet and Yew were more commonly recorded in urban hedges whereas Blackthorn, Bramble, Dog Rose, Elder and Hawthorn were recorded more often in rural hedges. Urban and rural differences were shown for some groups of invertebrates. Ants, earwigs and shieldbugs were recorded more frequently in urban hedges whereas blowflies, caterpillars, harvestmen, other beetles, spiders and weevils were recorded more frequently in rural hedges. Spiders were the most frequently recorded invertebrate across all surveys. The presence of hard surfaces adjacent to the hedge was influential on hedge structure, number and diversity of plant species, amount of food available for wildlife and invertebrate number and diversity. In urban hedges with one adjacent hard surface, the food available for wildlife was significantly reduced and in rural hedges, one adjacent hard surface affected the diversity of invertebrates. This research highlights that urban hedges may be important habitats for wildlife and that hard surfaces may have an impact on both the number and diversity of plant species and the number and diversity of invertebrates. This study demonstrates that citizen science programmes that focus on hedge surveillance can work and have the added benefit of educating the public on the importance of hedgerow habitats.

Urban public health is an important global issue, and receives extensive attention. It is necessary to compare urban public health status among different cities, so that each city can define its own health patterns and limiting factors. The following assessment indicators were established to evaluate urban public health status: living conditions, physical health, education and culture, environmental quality, and social security. A weighted-sum model was used in combination with these indicators to compare the urban public health status in four cities—Beijing, New York, London, and Tokyo—using data for 2000-2009. Although the urban public health level of Beijing was lower than that of the other cities, it showed the greatest increase in this level over the study period. Different patterns of urban public health were identified: London had the most balanced, steady pattern (almost all factors performed well and developed stably); New York and Tokyo showed balanced, but unsteady patterns (most factors remained high, though social security and environmental quality fluctuated); Beijing had the most unbalanced, unsteady pattern (the different factors were at different levels, and education and culture and social security fluctuated). For enhanced urban public health status, environmental quality and education and culture clearly need to be improved in Beijing. This study demonstrates that a comparison of different cities is helpful in identifying limiting factors for urban public health and providing an orientation for future urban development.

Soundscape of Urban Open Spaces in Hong Kong

NASA Astrophysics Data System (ADS)

Lin, Hui

This study aims to investigate the soundscape of urban open spaces in Hong Kong. Open space in densely populated cities has been considered as an important asset for urban inhabitants in that they afford opportunities for leisure, recreation and an active involvement with nature. For quite a long time, visual aesthetic was the dominant consideration in open space design and other senses were given less concern. Continuous stream of attention-demanding sounds from the noisy environment may bombard these open spaces, rendering them no longer able to satisfy the eye alone. Sound and consequently the acoustic environment are receiving increasing attention. This study used noise mapping technique supplemented by GIS spatial analysis tools to delineate quiet open spaces with traffic noise exposure less than 60 dB (A) L10, 1h and conducted field observations to determine their usages. The identified quiet open spaces are either concentrated in hilly and remote areas with low accessibility, or sporadically scattered among tall buildings. Some large urban parks and small sitting-out areas are even located in the center of the city. Larger open spaces serve group visits, such as hiking and sightseeing, while smaller ones are easily accessible to local residents for social and recreational purposes. The acoustic environment III urban open spaces varies with space and time. To characterize the acoustic quality of soundscapes in the quiet open spaces, sound walk and field recording were undertaken place in 25 selected study sites. Despite the dominance of traffic noise, soundscapes in the urban open spaces are also shaped by natural sounds. Sounds from birds and water are common and prevalent particularly in gardens and playgrounds. Soundscape approach is a human-centered point of view. How the visitors perceive and evaluate sounds and the acoustic quality has great implication for soundscape design. On-site interview of 1,610 visitors unravels human preference of individual sounds and evaluation of the acoustic quality. Sounds from bird, wind and water are most preferred, while mechanical sounds and road traffic noise are least favored. Human voice is rated in between. Brown's soundscape evaluation framework was substantiated by data collected in this study highlighting tbe importance of context and presence of wanted and unwanted sounds on subjective evaluation of the acoustic quality. Ordinal Logistic Regression models were developed with significant independent variables, including social-demographic factors, acoustic parameters, visiting habits and presence of wanted and unwanted sounds. Research findings have great implications for soundscape design of open spaces in compact cities. A properly designed open space offers a comfortable setting for relief, retreat and rejuvenation from tbe urban life. Endeavors to improve the acoustic quality in the urban open spaces will make cities more livable and sustainable.

Numerical Simulation of Dispersion from Urban Greenhouse Gas Sources

2017-04-01

Cities are characterized by complex topography, inhomogeneous turbulence, and variable pollutant source distributions. These features create a scale separation between local sources and urban scale emissions estimates known as the Grey-Zone. Modern computational fluid dynamics (CFD) techniques provide a quasi-deterministic, physically based toolset to bridge the scale separation gap between source level dynamics, local measurements, and urban scale emissions inventories. CFD has the capability to represent complex building topography and capture detailed 3D turbulence fields in the urban boundary layer. This presentation discusses the application of OpenFOAM to urban CFD simulations of natural gas leaks in cities. OpenFOAM is an open source software for advanced numerical simulation of engineering and environmental fluid flows. When combined with free or low cost computer aided drawing and GIS, OpenFOAM generates a detailed, 3D representation of urban wind fields. OpenFOAM was applied to model scalar emissions from various components of the natural gas distribution system, to study the impact of urban meteorology on mobile greenhouse gas measurements. The numerical experiments demonstrate that CH4 concentration profiles are highly sensitive to the relative location of emission sources and buildings. Sources separated by distances of 5-10 meters showed significant differences in vertical dispersion of plumes, due to building wake effects. The OpenFOAM flow fields were combined with an inverse, stochastic dispersion model to quantify and visualize the sensitivity of point sensors to upwind sources in various built environments. The Boussinesq approximation was applied to investigate the effects of canopy layer temperature gradients and convection on sensor footprints.

Staff turnover rates in publicly-funded mental health settings are high. We investigated staff and organizational predictors of turnover in a sample of individuals working in an urban public mental health system that has engaged in a system-level effort to implement evidence-based practices. Additionally, we interviewed staff to understand reasons for turnover. Greater staff burnout predicted increased turnover, more openness toward new practices predicted retention, and more professional recognition predicted increased turnover. Staff reported leaving their organizations because of personal, organizational, and financial reasons; just over half of staff that left their organization stayed in the public mental health sector. Implications include an imperative to focus on turnover, with a particular emphasis on ameliorating staff burnout. PMID:26179469

Spatial Character Analysis of Streets as Public Spaces: The Case of Izmit Hurriyet and Cumhuriyet Street, Turkey

NASA Astrophysics Data System (ADS)

Özbayraktar, Mehtap; Pekdemir, Merve; Mırzaliyeva, Gumru

2017-10-01

The word “public” was first used to refer to the theatre audience in France in the mid-17th century. In the 18th century, it turned into the meaning of “public space incorporating a large variety of people and composed of acquaintances and strangers”. The concepts of publicity, public space, and public realm have been studied and described by many researchers in the course of time. These descriptions show the development of public space as well. In the very general sense, public spaces are areas of personal and social happiness; collective living spaces of the society; areas of expression of natural and cultural variety; and key elements providing a ground for the establishment of an identity. In the United Nations’ report on public spaces, public space is addressed under six groups: 1. The spaces we intensely used in our daily life; 2. Green open public spaces; 3. Public activity spaces which users can go in without any difficulty, are open to public, and are under protection; 4. Public sector realm (social agreements in which the people are represented, contribute to collective goods, and trust in the administrators elected); 5. City as a public space; 6. Cyberspace. As cities grow, public spaces transform and diversify. Attempts are made to meet the changing needs through types of space developed. However, the character of the existing public spaces, the distribution of open spaces and parks and their inadequacy, the destruction of public space, and the things that are required to be done stand as important issues to be addressed. One of the public spaces going through transformation are streets which we intensely use in our daily life. In general, streets are defined as roads with buildings on both sides in settlements such as provinces and districts whose boundaries are determined by neighbouring buildings. Some researchers have defined streets based on their social functions. According to them, streets are meeting spaces; spaces to deal with strangers; the house of the society; the main elements of urban existence; spaces as changeable as life; symbolic models of urban problems; and symbols of free city. However, the role of streets, which are so important in our daily life, has only been reduced to pass. They have been divided into two between pedestrians and vehicles and lost many social functions of theirs. Accordingly, the present study aims to answer the question of whether the abovementioned features and characters of streets as public spaces are still maintained with special reference to a street, which is one of the main streets of Izmit, Turkey. The street, which was called İmre Tökeli Avenue, Hamidiye Street (1908), and Demiryolu Tekeli Street (1948) in the course of time, is currently called Hürriyet and Cumhuriyet Street. The people also call it “walking road”. According to the sources, the history of this street is the history of Izmit as well. The past and present spatial character of the study area will be revealed through archive reviews, city development plants, face-to-face interviews, and surveys. Problems will be determined, and recommendations will be developed.

Improving the quality of urban public space through the identification of space utilization index at Imam Bonjol Park, Padang city

Eriawan, Tomi; Setiawati, Lestari

2017-06-01

Padang City as a big city with a population approaching one million people has to address the issue of increased activities of the population and increased need for land and space for those activities. One of the effects of population growth and the development of activities in Padang is the decreasing number of open spaces for the outdoor public activities, both the natural and artificial public. However, Padang City has several open spaces that are built and managed by the government including 40 units of open spaces in the form of plansum parks, playgrounds, and sports parks, with a total area of 10.88 hectares. Despite their status as public open spaces, not all of them can be used and enjoyed by the public since most of them are passive parks, in which they are made only as a garden without any indulgences. This study was performed to assess the quality of public spaces in the central business of Padang City, namely Imam Bonjol Park (Taman Imam Bonjol). The methods of this study were done through several stages, which were to identify the typology of function space based on [1] Carmona (2008) and to assess the space utilization index based on the approach of Public Space Index according to Mehta [2] (2007). The purpose of this study was to assess the quality of space which is a public space in Padang City. The space quality was measured based on the variables in Good Public Space Index, the intensity of use, the intensity of social activity, the duration of activity, the variations in usage, and the diversity of use. The rate of the index of public space quality at Taman Imam Bonjol was determined by assessing 5 (five) variables of space quality. Based on the results of the analysis, public space utilization index was equal to 0.696. This result could be used to determine the quality of public space, in this case was Imam Bonjol Park was in Medium category. The parameters indicated several results including the lack of diversity in users' activity time, less formation of social interaction between users, and the relatively short average of visitors' duration in exploiting public space.

Ornamental flowers commonly grown in urban gardens and parks can be of value to flower-visiting insects. However, there is huge variation in the number of insects attracted among plant varieties. In this study, we quantified the insect attractiveness of 79 varieties in full bloom being grown in a public urban garden that is popular due to its beautiful flowers and other attractions. The results showed very clearly that most varieties (77%, n = 61) were either poorly attractive or completely unattractive to insect flower visitors. Several varieties (19%, n = 15) were moderately attractive, but very few (4%, n = 3) were highly attractive. Closer examination of Dahlia varieties showed that "open" flowered forms were approximately 20 times more attractive than "closed" flowered forms. These results strongly suggest that there is a great potential for making urban parks and gardens considerably more bee- and insect-friendly by selecting appropriate varieties. © 2014 Institute of Zoology, Chinese Academy of Sciences.

Open Source Tools for Numerical Simulation of Urban Greenhouse Gas Emissions

There is a global movement toward urbanization. Approximately 7% of the global population lives in just 28 megacities, occupying less than 0.1% of the total land area used by human activity worldwide. These cities contribute a significant fraction of the global budget of anthropogenic primary pollutants and greenhouse gasses. The 27 largest cities consume 9.9%, 9.3%, 6.7% and 3.0% of global gasoline, electricity, energy and water use, respectively. This impact motivates novel approaches to quantify and mitigate the growing contribution of megacity emissions to global climate change. Cities are characterized by complex topography, inhomogeneous turbulence, and variable pollutant source distributions. These features create a scale separation between local sources and urban scale emissions estimates known as the Grey-Zone. Modern computational fluid dynamics (CFD) techniques provide a quasi-deterministic, physically based toolset to bridge the scale separation gap between source level dynamics, local measurements, and urban scale emissions inventories. CFD has the capability to represent complex building topography and capture detailed 3D turbulence fields in the urban boundary layer. This presentation discusses the application of OpenFOAM to urban CFD simulations of natural gas leaks in cities. OpenFOAM is an open source software for advanced numerical simulation of engineering and environmental fluid flows. When combined with free or low cost computer aided drawing and GIS, OpenFOAM generates a detailed, 3D representation of urban wind fields. OpenFOAM was applied to model methane (CH4) emissions from various components of the natural gas distribution system, to investigate the impact of urban meteorology on mobile CH4 measurements. The numerical experiments demonstrate that CH4 concentration profiles are highly sensitive to the relative location of emission sources and buildings. Sources separated by distances of 5-10 meters showed significant differences in vertical dispersion of the plume due to building wake effects. The OpenFOAM flow fields were combined with an inverse, stochastic dispersion model to quantify and visualize the sensitivity of point sensors to upwind sources in various built environments.

Anthropogenic disruption of the night sky darkness in urban and rural areas.

The growing emissions of artificial light to the atmosphere are producing, among other effects, a significant increase of the night sky brightness (NSB) above its expected natural values. A permanent sensor network has been deployed in Galicia (northwest of Iberian peninsula) to monitor the anthropogenic disruption of the night sky darkness in a countrywide area. The network is composed of 14 detectors integrated in automated weather stations of MeteoGalicia, the Galician public meteorological agency. Zenithal NSB readings are taken every minute and the results are openly available in real time for researchers, interested stakeholders and the public at large through a dedicated website. The measurements allow one to assess the extent of the loss of the natural night in urban, periurban, transition and dark rural sites, as well as its daily and monthly time courses. Two metrics are introduced here to characterize the disruption of the night darkness across the year: the significant magnitude ( m 1/3 ) and the moonlight modulation factor ( γ ). The significant magnitude shows that in clear and moonless nights the zenithal night sky in the analysed urban settings is typically 14-23 times brighter than expected from a nominal natural dark sky. This factor lies in the range 7-8 in periurban sites, 1.6-2.5 in transition regions and 0.8-1.6 in rural and mountain dark sky places. The presence of clouds in urban areas strongly enhances the amount of scattered light, easily reaching amplification factors in excess of 25, in comparison with the light scattered in the same places under clear sky conditions. The periodic NSB modulation due to the Moon, still clearly visible in transition and rural places, is barely notable at periurban locations and is practically lost at urban sites.

The interrelationship of urban helicopter operations, helicopter noise, and the establishment of urban public-use heliports is discussed. Public resistance to urban helicopter operations due to concern for safety and noise is shown to negatively impact the establishment of public-use heliports in urban centers. It is indicated that increased government and industry effort to reduce helicopter noise is needed to ensure continued growth in the helicopter industry.

Access to child health services is an important determinant of child health. Whereas, child health indicators are generally better in urban than rural areas, some population groups in urban areas, such as children residing in urban slums do not enjoy this urban health advantage. In the context of increasing urbanisation and urban poverty manifesting with proliferation of urban slums, the health of under-five children in slum areas remains a public health imperative in Malawi. This paper explores healthcare-seeking practices for common childhood illnesses focusing on use of biomedical health services and perceived barriers to accessing under-five child health services in urban slums of Lilongwe, Malawi's capital city. Qualitative data from 8 focus group discussions with caregivers and 11 in-depth interviews with key informants conducted from September 2012 to April 2013 were analysed using conventional content analysis. Whereas, caregivers sought care from biomedical health providers, late care-seeking also emerged as a major theme and phenomenon. Home management was actively undertaken for childhood illnesses. Various health system barriers: lack of medicines and supplies; long waiting times; late facility opening times; negative attitude of health workers; suboptimal examination of the sick child; long distance to health facility; and cost of healthcare were cited in this qualitative inquiry as critical health system factors affecting healthcare-seeking for child health services. Interventions to strengthen the health system's responsiveness to expectations are essential to promote utilisation of child health services among urban slum populations, and ultimately improve child health and survival.

Despite US laws requiring most workplaces to provide "reasonable" unpaid break time and a private space for female employees to express breast milk, much of the statutory language is vague and open to interpretation, potentially leading to suboptimal implementation. College and university campuses in the US represent a particular concern, as students are typically not employed by their school and thus not protected by state and federal labor laws. This article describes the work of 2 graduate students to successfully establish a dedicated space at their US urban public university for the purpose of expressing breast milk. A 3-pronged strategy was implemented to create a dedicated lactation space: (1) collecting data to support the establishment of the room, (2) raising awareness of legislation related to protection of breastfeeding, and (3) community organizing and advocacy. After nearly 18 months of advocacy and planning, the campus' dedicated lactation room was opened for use in March 2012. Two years later, the room remains a valuable resource and is used, on average, 8.4 times per weekday during a typical school week. Several lessons learned are described, and the strategies employed can be tested and applied in other US academic settings to assist in advocating for more supports for breastfeeding mothers. However, it is also imperative that US legislation be amended to include language that explicitly protects students so that women do not need to make the choice between continuing their education and continuing to breastfeed. © The Author(s) 2015.

Urban forest has many functions mainly on improving the quality of the urban environment. One of the functions is to increase pH and reduce dangerous chemical content. The aim of the research is to find out the role of vegetation density of urban forest around the industrial area in reducing the acid rain. The condition of land cover was classified into four classes which are dense, medium, sparse and open area. The water of the throughfall and stemflow was taken from each type of land cover except in the open area. Parameters measured in this study are water acidity (pH), anion content (SO4 2- and NO3 -), cation content (Ca2+, Mg2+, and NH4 +) and electrical conductivity (EC). The results indicated that urban forest vegetation was able to increase the pH of rain water from 5.42 which is in an open area without vegetation to be 7.13 and 7.32 in dense and moderate vegetation cover by throughfall mechanism, respectively. Rain water acidity also decreased through stemflow mechanism with a pH ranged from 5.92 - 6.43. Urban forest vegetation decreased sulfate content (SO42-) from 528.67 mg/l in open area to 44 - 118 mg/l by throughfall mechanism and ranged from 90 to 366.67 mg/l through stemflow mechanism. Urban forest vegetation significantly decreased the rainwater nitrate content from 27 mg/l to 0.03 - 0.70 mg/l through the mechanism of throughfall and between 1.53 - 8.82 mg/l through the stemflow mechanism. Urban forest vegetation also increased the concentration of cations (NH4+, Ca2+, Mg2+, Na+) compared with open areas. Urban forest vegetation showed increased the electrical conductivity (EC) from 208.12 μmhos/cm to 344.67 - 902.17 μmhos/cm through the through fall mechanism and 937.67 - 1058.70 μmhos/cm through the stemflow mechanism. The study suggested that urban forests play a significant role in reducing rainwater acidity and improving the quality of rainwater that reached the soil surface.

The shortage and maldistribution of pediatricians affected after-hours pediatric services, especially in rural areas. Our study aimed to examine the urban-rural disparity in geographical and temporal availability of the pediatrician workforce in Taiwan by analyzing opening time schedules of all pediatric clinics throughout the country. The opening time schedules of nonhospital pediatric clinics were downloaded from the website of the National Health Insurance Administration in Taiwan for analysis. The geographical and temporal availability of pediatric clinics was calculated and stratified by urbanization level and opening time, which was divided into daytime and evening sessions over 1 week. Each of 368 towns in Taiwan was also regarded as a unit of measurement to estimate the local availability of at least one pediatric clinic open in after-hours sessions. Among 1483 nonhospital pediatric clinics in Taiwan, the overwhelming majority were situated in urban (65.8%) and suburban (30.6%) areas. On average, a pediatric clinic provided 16.3 (standard deviation=3.04) sessions of services per week. One-third (34.7%, n=50) of 144 suburban towns and over three-fourths (77.4%, n=120) of 155 rural towns had no pediatric clinic. Most pediatric clinics remained open on weekday evenings (91.1%) and during Saturday daytime (91.8%). The percentage of open clinics gradually decreased over the weekend: Saturday evening (58.1%), Sunday daytime (33.4%), and Sunday evening (19.4%). Rural pediatric clinics remained closed mostly on weekends. On Sunday evenings, pediatric clinics were open only in 5.2% of rural towns, with a decline of 77.1%, whereas they were open in 78.3% of urban towns, with a decline of 18.2%. Pediatric clinics in Taiwan were unevenly distributed between urban and rural areas. The disparity of pediatric services became more obvious at weekends. The consequences of undersupplied rural pediatric care deserve further investigation. Copyright © 2017. Published by Elsevier B.V.

The amount of land consumption required for housing and transport severely conflicts with both the necessity and the legal obligation to maintain the ecological potential afforded by open spaces to meet the needs of current and future generations with regards to the protection of resources and climate change. Owing to an increasing intensity of soil use, soil conditions appear to have deteriorated in most city regions around the world, namely their filter and runoff regulating functions are impaired by land surfacing. As such soil functions depend on the soil's biophysical properties and the degree of imperviousness, the impact on themore » water balance caused by urban growth varies considerably. In response to the demand for sustainably secure urban water resources, it needs to be assessed exactly how land surfacing affects the functions concerned. Analysing and evaluating urban land use change on the long-term water balance should improve our understanding of the impact of urbanisation on the water household. Therefore, this paper analyses the impact of urban land use change and land surfacing on the long-term urban water balance over a 130-year trajectory by using simple model approaches that are based on data available to the public. The test site is the city of Leipzig. In particular, attention is to be paid to estimating changes of evapotranspiration, direct runoff and groundwater recharge.« less

Recent advances in air pollution sensors have led to a new wave of low-cost measurement systems that can be deployed in dense networks to capture small-scale spatio-temporal variations in ozone, a pollutant known to cause negative human health impacts. This study deployed a network of seven low-cost ozone metal oxide sensor systems (UPods) in both an open space and an urban location in Boulder, Colorado during June and July of 2015, to quantify ozone variations on spatial scales ranging from 12 m between UPods to 6.7 km between open space and urban measurement sites with a measurement uncertainty of ~5 ppb. The results showed spatial variability of ozone at both deployment sites, with the largest differences between UPod measurements occurring during the afternoons. The peak median hourly difference between UPods was 6 ppb at 1:00 p.m. at the open space site, and 11 ppb at 4:00 p.m. at the urban site. Overall, the urban ozone measurements were higher than in the open space measurements. This study evaluates the effectiveness of using low-cost sensors to capture microscale spatial and temporal variation of ozone; additionally, it highlights the importance of field calibrations and measurement uncertainty quantification when deploying low-cost sensors.

The objective of this paper is to examine the dynamic impact of urbanization, economic growth, energy consumption, and trade openness on CO 2 emissions in Nigeria based on autoregressive distributed lags (ARDL) approach for the period of 1971-2011. The result shows that variables were cointegrated as null hypothesis was rejected at 1 % level of significance. The coefficients of long-run result reveal that urbanization does not have any significant impact on CO 2 emissions in Nigeria, economic growth, and energy consumption has a positive and significant impact on CO 2 emissions. However, trade openness has negative and significant impact on CO 2 emissions. Consumption of energy is among the main determinant of CO 2 emissions which is directly linked to the level of income. Despite the high level of urbanization in the country, consumption of energy still remains low due to lower income of the majority populace and this might be among the reasons why urbanization does not influence emissions of CO 2 in the country. Initiating more open economy policies will be welcoming in the Nigerian economy as the openness leads to the reduction of pollutants from the environment particularly CO 2 emissions which is the major gases that deteriorate physical environment.

Peak Oil, Urban Form, and Public Health: Exploring the Connections

PubMed Central

Kaza, Nikhil; Knaap, Gerrit-Jan; Knaap, Isolde

2011-01-01

We assessed the relationships between peak oil and urban form, travel behavior, and public health. Peak oil will affect the general economy, travel behavior, and urban form through income and substitution effects; however, because of the wide range of substitution possibilities, the impacts are likely to be gradual and relatively small. Furthermore, we suggest that changes in travel behavior and increases in urban density will have both favorable and unfavorable effects on public health. To mitigate the adverse impacts and to maximize the positive effects of peak oil, we recommend that careful attention should be paid to urban design and public health responses for a range of urbanization patterns.

An ecological public health approach to understanding the relationships between sustainable urban environments, public health and social equity.

PubMed

Bentley, Michael

2014-09-01

The environmental determinants of public health and social equity present many challenges to a sustainable urbanism-climate change, water shortages and oil dependency to name a few. There are many pathways from urban environments to human health. Numerous links have been described but some underlying mechanisms behind these relationships are less understood. Combining theory and methods is a way of understanding and explaining how the underlying structures of urban environments relate to public health and social equity. This paper proposes a model for an ecological public health, which can be used to explore these relationships. Four principles of an ecological public health-conviviality, equity, sustainability and global responsibility-are used to derive theoretical concepts that can inform ecological public health thinking, which, among other things, provides a way of exploring the underlying mechanisms that link urban environments to public health and social equity. Theories of more-than-human agency inform ways of living together (conviviality) in urban areas. Political ecology links the equity concerns about environmental and social justice. Resilience thinking offers a better way of coming to grips with sustainability. Integrating ecological ethics into public health considers the global consequences of local urban living and thus attends to global responsibility. This way of looking at the relationships between urban environments, public health and social equity answers the call to craft an ecological public health for the twenty-first century by re-imagining public health in a way that acknowledges humans as part of the ecosystem, not separate from it, though not central to it. © The Author (2013).

Zayas, Luis E; McLean, Don

2007-12-01

Disenfranchised ethnic minority communities in the urban United States experience a high burden of asthma. Conventional office-based patient education often is insufficient to promote proper asthma management and coping practices responsive to minority patients' environments. This paper explores existing and alternative asthma information and education sources in three urban minority communities in western New York State to help design other practical educational interventions. Four focus groups (n = 59) and four town hall meetings (n = 109) were conducted in one Hispanic and two black communities. Focus groups included adult asthmatics or caretakers of asthmatics, and town meetings were open to all residents. A critical theory perspective informed the study. Asthma information and education sources, perceptions of asthma and ways of coping were elicited through semi-structured interviews. Data analysis followed a theory-driven immersion-crystallization approach. Several asthma education and information resources from the health care system, media, public institutions and communities were identified. Intervention recommendations highlighted asthma workshops that recognize participants as teachers and learners, offer social support, promote advocacy, are culturally appropriate and community-based and include health care professionals. Community-based, group health education couched on people's experiences and societal conditions offers unique opportunities for patient asthma care empowerment in minority urban communities.

Gaseous polycyclic aromatic hydrocarbon concentrations are higher in urban forests than adjacent open areas during summer but not in winter--Exploratory study.

While the potential of plants to uptake polycyclic aromatic hydrocarbons (PAHs) is widely acknowledged, empirical evidence of the effects of this process on local atmospheric PAH concentrations and human health is tenuous. We measured gaseous PAH concentrations using passive samplers in urban tree-covered areas and adjacent open, treeless areas in a near-road environment in Finland to gain information on the ability of urban vegetation to improve air quality. The ability of urban, mostly deciduous, vegetation to affect PAHs was season dependent: during summer, concentrations were significantly higher in tree-covered areas, while in the fall, concentrations in open areas exceeded those in tree-covered areas. During winter, concentrations in tree-covered areas were either lower or did not differ from those in open areas. Results of this study imply that the commonly believed notion that trees unequivocally improve air quality does not apply to PAHs studied here. Copyright © 2015 Elsevier Ltd. All rights reserved.

Open Streets are community-based programs that promote the use of public space for physical activity (PA), recreation and socialization by closing streets temporarily to motorized vehicles, allowing access to pedestrians. The city of Atlanta hosted its first Open Streets event, Atlanta Streets Alive (ASA), in May 2010. An evaluation of the first 5 ASA events from May 2010 to May 2012 was conducted. The purpose was to learn about the characteristics of ASA participants, the influence of the event on their PA, and perceptions of safety and neighborhood social capital. ASA's evaluation had 2 components: participant counts and a participant survey. Characteristics of participation were compared among the 3 different events in which surveys were conducted using the Pearson χ2 test and F test as appropriate. The estimated participation at ASA increased from nearly 3,500 (ASA 1 to 4) to 12,520 (ASA 5). The number of events increased to 3 per year for a total of 10 events until 2014. Overall, 19.4% of participants met the weekly PA recommendation during 1 event. The expanding diversity of routes, participants, and sponsorships highlights the potential promise such programming offers in terms of establishing an urban culture of health.

Economic reforms and health insurance in China.

PubMed

Du, Juan

2009-08-01

During the 1990s, Chinese state-owned enterprises (SOEs) and collective enterprises continually decreased coverage of public health insurance to their employees. This paper investigates this changing pattern of health insurance coverage in China using panel data from the China Nutrition and Health Survey (1991-2000). It is the first attempt in this literature that tries to identify precisely the effects of specific policies and reforms on health insurance coverage in the transitional period of China. The fixed effects linear model clustering at the province level is used for estimation, and results are compared to alternative models, including pooled OLS, random effects GLS model and fixed effects logit model. Strong empirical evidence is found that unemployment as a side effect of the Open Door Policy, and the deregulation of SOE and collective enterprises were the main causes for the decreasing trend. For example, urban areas that were highly affected by the Open Door Policy were associated with 17 percentage points decrease in the insurance coverage. Moreover, I found evidence that the gaps between SOE and non-SOE employees, collective and non-collective employees, urban and rural employees have considerably decreased during the ten years.

2017-03-01

The urban corridor is more than just a linear space to circulation. It is a place for community activities. Since the urban area in Indonesia functionates without guidelines, it is necessary to analyze how this space being used by the community. The objective of the research is to explore the problems in utilization of public space in Dr. Mansur corridor in Medan and to propose some recommendation to improve it. The survey was started by mapping the physical situation that based on urban design aspects and the activities occur. Based on the data, the study identified the problems of the public space utilization. Next, study selected several buildings that significant in generating public life. The study interviewed the building’s owners and users/customers to get their opinion and perception about the using of urban public space utilization in the corridor in relation to their private function. The study analyzed the problems and opportunity to redesign the buildings that respect to public space. Then, the design ideas were presented to the buildings owners to get their response. The result of the observation shows that the fundamental problem in the corridor is the intervention of the private interest to the street as public space. The study indicates that the majority of the buildings owner was not aware that their buildings had distracted the urban public space. However, they gave a positive respond to the design recommendation. The design offered the solution that provided individual needs without intervention to the public realm. The study can contribute to improving urban corridor by educating the community with architecture and urban design.

Zou, Linghong; Dai, Hongna; Yao, Enjian; Jiang, Tian; Guo, Hongwei

2014-01-01

In recent years, with the rapid increase in urban population, the urban travel demands in Chinese cities have been increasing dramatically. As a result, developing comprehensive urban transport systems becomes an inevitable choice to meet the growing urban travel demands. In urban transport systems, public transport plays the leading role to promote sustainable urban development. This paper aims to establish an assessment index system for the development level of urban public transport consisting of a target layer, a criterion layer, and an index layer. Review on existing literature shows that methods used in evaluating urban public transport structure are dominantly qualitative. To overcome this shortcoming, fuzzy mathematics method is used for describing qualitative issues quantitatively, and AHP (analytic hierarchy process) is used to quantify expert's subjective judgment. The assessment model is established based on the fuzzy AHP. The weight of each index is determined through the AHP and the degree of membership of each index through the fuzzy assessment method to obtain the fuzzy synthetic assessment matrix. Finally, a case study is conducted to verify the rationality and practicability of the assessment system and the proposed assessment method.

The making of urban ‘healtheries’: the transformation of cemeteries and burial grounds in late-Victorian East London☆

PubMed Central

Brown, Tim

2013-01-01

This paper focuses on the conversion of disused burial grounds and cemeteries into gardens and playgrounds in East London from around the 1880s through to the end of the century. In addition to providing further empirical depth, especially relating to the work of philanthropic organisations such as the Metropolitan Public Gardens Association, the article brings into the foreground debates regarding the importance of such spaces to the promotion of the physical and moral health of the urban poor. Of particular note here is the recognition that ideas about the virtuous properties of open, green space were central to the success of attempts at social amelioration. In addition to identifying the importance of such ideas to the discourse of urban sanitary reformers, the paper considers the significance of less virtuous spaces to it; notably here, the street. Building on Driver's work on ‘moral environmentalism’ and Osborne and Rose's on ‘ethicohygienic space,’ this paper goes on to explore the significance of habit to the establishing of what Brabazon called ‘healtheries’ in late-Victorian East London.

Evaluating the performance of ENVI-met model in diurnal cycles for different meteorological conditions

NASA Astrophysics Data System (ADS)

Acero, Juan A.; Arrizabalaga, Jon

2018-01-01

Urban areas are known to modify meteorological variables producing important differences in small spatial scales (i.e. microscale). These affect human thermal comfort conditions and the dispersion of pollutants, especially those emitted inside the urban area, which finally influence quality of life and the use of public open spaces. In this study, the diurnal evolution of meteorological variables measured in four urban spaces is compared with the results provided by ENVI-met (v 4.0). Measurements were carried out during 3 days with different meteorological conditions in Bilbao in the north of the Iberian Peninsula. The evaluation of the model accuracy (i.e. the degree to which modelled values approach measured values) was carried out with several quantitative difference metrics. The results for air temperature and humidity show a good agreement of measured and modelled values independently of the regional meteorological conditions. However, in the case of mean radiant temperature and wind speed, relevant differences are encountered highlighting the limitation of the model to estimate these meteorological variables precisely during diurnal cycles, in the considered evaluation conditions (sites and weather).

Anthropogenic activities alter the urban surface and surface atmosphere, generating heat and pollutants that have known detrimental impacts on health. Monitoring these environmental variables in urban environments is made difficult by the spatial heterogeneity of urban environments, meaning that two nearby locations may have significantly different temperatures, humidities, or gas concentrations. Thus, urban monitoring often requires more densely placed monitors than current standards or budgets allow. Recent advances in low-cost sensors and Internet of Things (IoT) enabled hardware offer possible solutions. We present an autonomous wireless, open-source, IoT-enabled environmental monitor called a WeatherCube, developed for the Greater Baltimore Open Air project, funded in part by the EPA SmartCity Challenge. The WeatherCube is suitable for urban monitoring and capable of measuring meteorological variables (temperature and humidity) as well as air quality (ozone, nitrogen dioxide, and sulfur dioxide). The WeatherCube devices were built in collaboration with Johns Hopkins University, local government, and community members, including through an innovative job training program. Monitors are hosted by community partners and libraries throughout Baltimore city and surrounding communities. We present the first wave of data collected by the Greater Baltimore Open Air project and compare it to data collected by the Maryland Department of the Environment (MDE). Additionally, we will provide an overview of our experience engaging with the local makers, citizen scientists, and environmental groups to improve their urban environmental monitoring. By developing low-cost devices tailored for urban environmental monitoring, we present an innovative model for both conducting research and community outreach.

Public green areas and urban environmental quality of the city of São Carlos, São Paulo, Brazil.

2016-04-19

Assess the state of public green areas, their importance and influence on environmental quality and living in urban centers is an arduous task considering the conceptual and scientific regarding quantification and data analysis methods divergence. In this study, we aimed to determine two indicators of public green areas relative to the percentage of public green areas (PPGA) and the public green areas index (PGAI) in the urban area of São Carlos, SP. The study area was organized into administrative regions (ARs), using satellite images, topographical maps of 1:10,000 Geographic and Cartographic Institute (1990) and data provided by the Municipality of São Carlos. The results show that public green areas comprise 6.55% of the municipality, with a public green areas index (PGAI) of 18.85 m2/inhabitant, indicating good urban environmental quality when compared to rates of 15 m2/capita for public green areas for recreation, suggested by the Brazilian Society of Urban Forestry. The differences between the administrative regions are concern with situations from 4.16 to 36.30 m2/inhabitant. In this context, it is recommend specific public policies and popular participation in the process of continuous improvement for increasing public green areas in the less favored regions. The Genebrino method applied to indicators of public green areas (GPGA - amount of public green areas divided by population density), showed a commendable goal above 40% for urban environmental quality.

The four cultures: Public engagement with science only, art only, neither, or both museums.

PubMed

Shein, Paichi Pat; Li, Yuh-Yuh; Huang, Tai-Chu

2015-11-01

This study uses an art-and-science comparative lens to understand the science culture, particularly the public engagement with science museums. A representational Taiwanese sample of 1863 subjects was categorized into "four cultures," who visit science only, art only, neither, or both museums, resulting in six multivariate logistic regression models. Knowledge of science, interests in scientific and social issues, and socio-demographic variables were considered in the models. Adults with children and males prefer science museums, females prefer art museums, and the young and urban intellects show no strong preference, appearing to be open to both science and art museums. The findings show the complex decisions the public make in visiting museums. It is no longer a strictly science or art decision, as framed by Snow's "The Two Cultures" argument; rather, the possibility of visiting both museums has emerged, a phenomenon we describe as cognitive polyphasia. © The Author(s) 2015.

Exploring Association between Morphology of Tree Planting and User Activities in Urban Public Space; An opportunity of Urban Public Space Revitalisation

NASA Astrophysics Data System (ADS)

Shen, Qi; Liu, Yan

2018-03-01

This paper discusses the association between the morphology of tree planting in urban riverside brown field and user activities. With the growth of popularity, the revitalisation of urban public space is also promising. This research used drone photography and mapping to systematically surveys sample sites. An original observation study of user activities proceed in four sample public spaces in Sheffield. The study results found there are huge popularity and duration difference of user activities between various tree planting morphologies and typologies. The public space with lawn and rounded by mature trees attracted most users with the most activity types; the neat and silent public space is the favourite choice of lunch and reading, meanwhile it got the longest activity duration; but the space with sparse morphology and small trees are more likely be forgotten and abandoned. This finding offered a great opportunity for urban public space revitalisation in post-industrial cities.

2014-05-01

The frequency and damages caused by pluvial floods in European cities are expected to increase as a consequence of climate change and urban development. New solutions are needed at local level to cope with extreme storm events and to reduce risks and costs on populations and infrastructures, in particular in disadvantaged urban areas. The HM&Co team (LEESU & Chair 'Hydrology for Resilient Cities' sponsored by Veolia) aims to develop resilient urban systems with the help of innovative technologies, tools and practices based in particular on the use of high-resolution data, simulations, forecasts and management. Indeed, the availability of fine-scale rainfall data, due to the improved reliability of recent low-cost weather radars, opens up prospects for new forms of local urban flood risk management, which requires exchange of information with local actors and their full cooperation with researchers. This demands a large collaboration ranging from regional to international levels, e.g. the RadX@IdF project (Regional Council of Paris Region), the RainGain project (EU Interreg programme) and Blue Green Dream project (Climate-KIC programme), TOMACS (World Meteorological Organisation). These research projects and programmes include awareness raising and capacity building activities aimed to stimulate cooperation between scientists, professionals (e.g. water managers, urban planners) and beneficiaries (e.g. concerned citizens, policy makers). A dialogue between these actors is indeed needed to bring together the know-how from different countries and areas of expertise, avoid fragmentation and link it to the needs of the local stakeholders. Without this "conductive environment", research results risk to remain unexploited. After a general description of the background communication needs, this presentation will illustrate the outreach practices that are carried out by the HM&Co team. The major challenges will be also discussed, some examples are: narrating research uncertainty and its open issues as a virtuous process, aligning diverging objectives and approaches in a common vision, making an innovative technology visible to the public and managing rumours on security issues, bridging the gap between scientific discourses from an international academic community and operational discourses from local communities.

Valuing the benefits of creek rehabilitation: building a business case for public investments in urban green infrastructure.

Mekala, Gayathri Devi; Jones, Roger N; MacDonald, Darla Hatton

2015-06-01

In an effort to increase the livability of its cities, public agencies in Australia are investing in green infrastructure to improve public health, reduce heat island effects and transition toward water sensitive urban design. In this paper, we present a simple and replicable approach to building a business case for green infrastructure. This approach requires much less time and resources compared to other methods for estimating the social and economic returns to society from such investments. It is a pragmatic, reasonably comprehensive approach that includes socio-demographic profile of potential users and catchment analysis to assess the economic value of community benefits of the investment. The approach has been applied to a case study area in the City of Brimbank, a western suburb of Greater Melbourne. We find that subject to a set of assumptions, a reasonable business case can be made. We estimate potential public benefits of avoided health costs of about AU$75,049 per annum and potential private benefits of AU$3.9 million. The project area is one of the most poorly serviced areas in the municipality in terms of quality open spaces and the potential beneficiaries are from relatively low income households with less than average health status and education levels. The values of cultural (recreational benefits, avoided health costs, and increased property values) and regulating (reduction in heat island effect and carbon sequestration) ecosystem services were quantified that can potentially offset annual maintenance costs.

Open source 3D visualization and interaction dedicated to hydrological models

2014-05-01

Climate change and surface urbanization strongly modify the hydrological cycle in urban areas, increasing the consequences of extreme events such as floods or draughts. These issues lead to the development of the Multi-Hydro model at the Ecole des Ponts ParisTech (A. Giangola-Murzyn et al., 2012). This fully distributed model allows to compute the hydrological response of urban and peri-urban areas. Unfortunately such models are seldom user friendly. Indeed generating the inputs before launching a new simulation is usually a tricky tasks, and understanding and interpreting the outputs remains specialist tasks not accessible to the wider public. The MH-AssimTool was developed to overcome these issues. To enable an easier and improved understanding of the model outputs, we decided to convert the raw output data (grids file in ascii format) to a 3D display. Some commercial paying models provide a 3D visualization. Because of the cost of their licenses, this kind of tools may not be accessible to the most concerned stakeholders. So, we are developing a new tool based on C++ for the computation, Qt for the graphic user interface, QGIS for the geographical side and OpenGL for the 3D display. All these languages and libraries are open source and multi-platform. We will discuss some preprocessing issues for the data conversion from 2.5D to 3D. Indeed, the GIS data, is considered as a 2.5D (e.i. 2D polygon + one height) and the its transform to 3D display implies a lot of algorithms. For example,to visualize in 3D one building, it is needed to have for each point the coordinates and the elevation according to the topography. Furthermore one have to create new points to represent the walls. Finally the interactions between the model and stakeholders through this new interface and how this helps converting a research tool into a an efficient operational decision tool will be discussed. This ongoing research on the improvement of the visualization methods is supported by the KIC-Climate Blue Green Dream project.

CO2 emissions, real output, energy consumption, trade, urbanization and financial development: testing the EKC hypothesis for the USA.

PubMed

Dogan, Eyup; Turkekul, Berna

2016-01-01

This study aims to investigate the relationship between carbon dioxide (CO2) emissions, energy consumption, real output (GDP), the square of real output (GDP(2)), trade openness, urbanization, and financial development in the USA for the period 1960-2010. The bounds testing for cointegration indicates that the analyzed variables are cointegrated. In the long run, energy consumption and urbanization increase environmental degradation while financial development has no effect on it, and trade leads to environmental improvements. In addition, this study does not support the validity of the environmental Kuznets curve (EKC) hypothesis for the USA because real output leads to environmental improvements while GDP(2) increases the levels of gas emissions. The results from the Granger causality test show that there is bidirectional causality between CO2 and GDP, CO2 and energy consumption, CO2 and urbanization, GDP and urbanization, and GDP and trade openness while no causality is determined between CO2 and trade openness, and gas emissions and financial development. In addition, we have enough evidence to support one-way causality running from GDP to energy consumption, from financial development to output, and from urbanization to financial development. In light of the long-run estimates and the Granger causality analysis, the US government should take into account the importance of trade openness, urbanization, and financial development in controlling for the levels of GDP and pollution. Moreover, it should be noted that the development of efficient energy policies likely contributes to lower CO2 emissions without harming real output.

We describe the development, feasibility, and acceptability of a novel preventive intervention for depression in African American girls living in urban poverty. Our approach targeted individual and interpersonal vulnerabilities that have been shown to confer risk for depression in samples of African American girls living in low-income, urban settings, including suppression of negative emotion and lack of assertiveness with peers, memory for positive emotion, active coping, and family connection. Focus groups and an open trial were conducted to refine the goals and mechanisms for skill building. A randomized controlled trial (RCT) of the new program (Cities Mother-Daughter Project) was conducted with 3rd-5th grade students from Chicago Public Schools (CPS). Three cycles of screening, randomization, and deployment were conducted to assess feasibility, satisfaction, and usability. Results indicate that feasibility was weak; whereas, satisfaction and usability were high. Future directions for testing efficacy are discussed.

Faculty experiences with the National Institutes of Health (NIH) public access policy, compliance issues, and copyright practices.

Charbonneau, Deborah H; McGlone, Jonathan

2013-01-01

The research assessed faculty awareness of the National Institutes of Health (NIH) public access policy and faculty experiences with the copyright terms in their author agreements with publishers. During the fall of 2011, 198 faculty members receiving funding from NIH at a large urban academic institution were invited to participate in an anonymous online survey. A total of 94 faculty members responded to the survey, representing a response rate of 47%. Thirty percent of the survey respondents were either unaware of or not familiar with the NIH policy. Further, a significant number of faculty members (97.8%) indicated that they usually signed their copyright forms "as is." The findings show that time, confusing instructions, and unclear journal policies are challenges experienced by NIH-funded faculty in complying with the federal mandate. There is a need to educate faculty with respect to the value of retaining their copyrights and self-archiving their publications to help advance public access and open access scholarship.

2013-08-01

A repeated cross-sectional study was conducted to determine the prevalence of Campylobacter spp. and the population structure of C. jejuni in European starlings and ducks cohabiting multiple public access sites in an urban area of New Zealand. The country's geographical isolation and relatively recent history of introduction of wild bird species, including the European starling and mallard duck, create an ideal setting to explore the impact of geographical separation on the population biology of C. jejuni, as well as potential public health implications. A total of 716 starling and 720 duck fecal samples were collected and screened for C. jejuni over a 12 month period. This study combined molecular genotyping, population genetics and epidemiological modeling and revealed: (i) higher Campylobacter spp. isolation in starlings (46%) compared with ducks (30%), but similar isolation of C. jejuni in ducks (23%) and starlings (21%), (ii) significant associations between the isolation of Campylobacter spp. and host species, sampling location and time of year using logistic regression, (iii) evidence of population differentiation, as indicated by FST , and host-genotype association with clonal complexes CC ST-177 and CC ST-682 associated with starlings, and clonal complexes CC ST-1034, CC ST-692, and CC ST-1332 associated with ducks, and (iv) greater genetic diversity and genotype richness in ducks compared with starlings. These findings provide evidence that host-associated genotypes, such as the starling-associated ST-177 and ST-682, represent lineages that were introduced with the host species in the 19th century. The isolation of sequence types associated with human disease in New Zealand indicate that wild ducks and starlings need to be considered as a potential public health risk, particularly in urban areas. © 2013 The Authors.

This research aims to explore the feasibility of using computer-based models to predict the soundscape quality evaluation of potential users in urban open spaces at the design stage. With the data from large scale field surveys in 19 urban open spaces across Europe and China, the importance of various physical, behavioral, social, demographical, and psychological factors for the soundscape evaluation has been statistically analyzed. Artificial neural network (ANN) models have then been explored at three levels. It has been shown that for both subjective sound level and acoustic comfort evaluation, a general model for all the case study sites is less feasible due to the complex physical and social environments in urban open spaces; models based on individual case study sites perform well but the application range is limited; and specific models for certain types of location/function would be reliable and practical. The performance of acoustic comfort models is considerably better than that of sound level models. Based on the ANN models, soundscape quality maps can be produced and this has been demonstrated with an example.

The European Open Data Strategy establishes important new principles that ensure that European public sector data will be released at no cost (or marginal cost), in machine-readable, commonly-understood formats, and with liberal licences enabling wide reuse. These data encompass both scientific data about the environment (from Earth Observation and other fields) and other public sector information, including diverse topics such as demographics, health and crime. Many open geospatial datasets (e.g. land use) are already available through the INSPIRE directive and made available through infrastructures such as the Global Earth Observation System of Systems (GEOSS). The intention of the Open Data Strategy is to stimulate the growth of research and value-adding services that build upon these data streams; however, the potential value inherent in open data, and the benefits that can be gained by combining previously-disparate sources of information are only just starting to become understood. The MELODIES project (Maximising the Exploitation of Linked Open Data In Enterprise and Science) is developing eight innovative and sustainable services, based upon Open Data, for users in research, government, industry and the general public in a broad range of societal and environmental benefit areas. MELODIES (http://melodiesproject.eu) is a European FP7 project that is coordinated by the University of Reading and has sixteen partners (including nine SMEs) from eight European countries. It started in November 2013 and will run for three years. The project is therefore in its early stages and therefore we will value the opportunity that this workshop affords to present our plans and interact with the wider Linked Geospatial Data community. The project is developing eight new services[1] covering a range of domains including agriculture, urban ecosystems, land use management, marine information, desertification, crisis management and hydrology. These services will combine Earth Observation data with other open data sources to produce new information for the benefit of scientists, industry, government decision-makers, public service providers and citizens. The long-term sustainability of the services will be assessed critically throughout the project from a number of angles (technical, political and economic), in order to ensure that the full benefits of the MELODIES project are realised in the long term. The priority of the project, therefore, is to demonstrate that releasing data openly leads to concrete commercial and scientific benefits, and can stimulate the production of new applications and viable services.

Sauvons le Luxembourg: urban greenspace as private domain and public battleground, 1865-1867.

PubMed

Hopkins, Richard S

2011-01-01

This article examines the way in which public response to a municipal proposal concerning greenspace reduction in Paris during the Second Empire reflected not only political antipathy but also an ever-increasing understanding of public urban greenspace as part of the private domain. By examining archival records concerning the proposal, essays, newspaper accounts, and memoirs, this article argues that a particular proprietary sensibility, fomented by expansive public greenspace development in Paris, intersected with extant social constructs and political tensions to create a public, coordinated, and sustained challenge to the authoritarian regime. Thus, the battle over the Luxembourg Garden became more than just a fight to prevent a reduction in size of a particular public urban greenspace. Rather, public debate surrounding alteration of this garden underscores the extent to which public greenspace, in general, was urban space that blurred the public—private boundary and presented unique opportunities for community formation, social integration, and political action.

Research demonstrating the biophysical benefits of urban trees are often used to justify investments in urban forestry. Far less emphasis, however, is placed on the non-bio-physical benefits such as improvements in public health. Indeed, the public-health benefits of trees may be significantly larger than the biophysical benefits, and, therefore, failure to account for...

A disadvantaged advantage in walkability: findings from socioeconomic and geographical analysis of national built environment data in the United States.

Urban form-the structure of the built environment-can influence physical activity, yet little is known about how walkable design differs according to neighborhood sociodemographic composition. We studied how walkable urban form varies by neighborhood sociodemographic composition, region, and urbanicity across the United States. Using linear regression models and 2000-2001 US Census data, we investigated the relationship between 5 neighborhood census characteristics (income, education, racial/ethnic composition, age distribution, and sex) and 5 walkability indicators in almost 65,000 census tracts in 48 states and the District of Columbia. Data on the built environment were obtained from the RAND Corporation's (Santa Monica, California) Center for Population Health and Health Disparities (median block length, street segment, and node density) and the US Geological Survey's National Land Cover Database (proportion open space and proportion highly developed). Disadvantaged neighborhoods and those with more educated residents were more walkable (i.e., shorter block length, greater street node density, more developed land use, and higher density of street segments). However, tracts with a higher proportion of children and older adults were less walkable (fewer street nodes and lower density of street segments), after adjustment for region and level of urbanicity. Research and policy on the walkability-health link should give nuanced attention to the gap between persons living in walkable areas and those for whom walkability has the most to offer.

2017-11-01

Balikpapan city has transformed from oil city to trade and industry center. In the last 5 years, industry and trade sectors experienced annual economic growth by more than 25%, while mining had only 0.05%. This condition raised a strong economic attraction which increased urban activities and population growth, especially urbanization process. Nevertheless, the growth of the city had a challenge in the urban water supply. Due to natural condition of the city, Balikpapan does not have a large river, making water supply conducted by reservoirs relying on rainfall intensity. In line with population growth and conversion of green open space, the city government should consider to the allocation of land use effectively based on sustainable water resources. As the associated pressure on water resources continued to increase, it is crucial to identify the water demand future in Balikpapan City related to domestic and non-domestic activities as the first step to optimize land use allocation. Domestic's activities is defined as household and public hydrant, while non-domestic sectors are public facilities, offices, trade and services, and industrial areas. Mathematical calculations, population projections and water consumption estimation, were used as analysis methods. Analysis result showed that the total the city population in 2025 amounted to 740.302 people, increasing by 14.5% from 2016. Population growth increased the urban water needs. From the calculations, the amount of water consumption in 2016 amounted to 5075.77 liter/s, and in 2025 to 7528.59 liter/s. Thus, the water needs of the population of Balikpapan from 2016-2025 year increased by 32.58%.

The Influence of Green Infrastructure on Urban Resilience in Greater London

NASA Astrophysics Data System (ADS)

Oh, Yukyung

2017-04-01

High population densities and diverse economic activities in urban areas create social issues as well as a range of environmental impacts including air pollution, soil contamination, loss of biodiversity and health problems (Alberti et al., 2003; Dobbs, Escobedo, & Zipperer, 2011; Grimm et al., 2008). The concept of urban resilience has been used for increasing the capacity of the entities and players to adapt to rapid changes, and urban green spaces play a crucial role in increasing urban resilience. Greater London has a good case for increasing urban green spaces and resilience under the London Plan. The relevance of urban open spaces and several socioeconomic indicators would provide researchers and policy makers with the information for managing green coverage. The correlation analysis of two quantitative data such as open space and socioeconomic data of Greater London was conducted with SPSS. The data for open spaces in Greater London was gained through Greenspace Information for Greater London. The data was converted from vector to raster in Geographic Information System (GIS), so as to calculate landscape metrics for open spaces in Greater London through a spatial pattern analysis program, FRAGSTATS 4.2. The socioeconomic data was obtained from "London Borough Profile", London Datastore. In addition, data on total carbon emissions from Industry and Commercial, Domestic, Transport, LULUCF Net Emissions, and per capita emissions were gained from UK local authority and regional carbon dioxide emissions national statistics: 2005-2014 released from Department of Energy and Climate Change. The indicators from open spaces are total area of open space and patch density or contagion of open spaces. The latter indicator allows to figure out the level of fragmentation of open spaces. The socioeconomic indicators cover number of jobs by workplace, jobs density, crime rates per thousand population, and several wellbeing indicators such as life satisfaction, worthwhileness, happiness and anxiety. The correlation analysis outcomes can be divided into three levels such as Greater London as a whole, and Inner and Outer London. In Greater London, total area of green spaces has a strong relation with crime rates, and a less strong relation with number of jobs. Both socioeconomic indicators showed a negative trend along with the increase of open spaces. In terms of wellbeing indicators, the positive trend of life satisfaction, worthwhileness and happiness, and the negative trend of anxiety can be found in accordance with the increase of green coverage. In Inner London, job density and crime rates show a negative trend in accordance with the increase of total open space areas. And as contagion of open spaces is higher, the indicators of number of jobs, jobs density, and crime rates also showed an increase tendency. As for worthwhileness and happiness, it also showed a substantial correlation with contagion of open spaces. In Outer London, the correlation between job density and crime rates, and open space cannot be found, but the wellbeing indicators such as life satisfaction and worthwhileness show an increase trend along with larger green coverage.

Urban sprawl and the related landscape fragmentation is a Europe-wide challenge in the context of sustainable urban planning. The URBan land recycling Information services for Sustainable cities (URBIS) project aims for the development, implementation, and validation of web-based information services for urban vacant land in European functional urban areas in order to provide end-users with site specific characteristics and to facilitate the identification and evaluation of potential development areas. The URBIS services are developed based on open geospatial data. In particular, the Copernicus Urban Atlas thematic layers serve as the main data source for an initial inventory of sites. In combination with remotely sensed data like SPOT5 images and ancillary datasets like OpenStreetMap, detailed site specific information is extracted. Services are defined for three main categories: i) baseline services, which comprise an initial inventory and typology of urban land, ii) update services, which provide a regular inventory update as well as an analysis of urban land use dynamics and changes, and iii) thematic services, which deliver specific information tailored to end-users' needs.

Research on Assessment Methods for Urban Public Transport Development in China

PubMed Central

Zou, Linghong; Guo, Hongwei

2014-01-01

In recent years, with the rapid increase in urban population, the urban travel demands in Chinese cities have been increasing dramatically. As a result, developing comprehensive urban transport systems becomes an inevitable choice to meet the growing urban travel demands. In urban transport systems, public transport plays the leading role to promote sustainable urban development. This paper aims to establish an assessment index system for the development level of urban public transport consisting of a target layer, a criterion layer, and an index layer. Review on existing literature shows that methods used in evaluating urban public transport structure are dominantly qualitative. To overcome this shortcoming, fuzzy mathematics method is used for describing qualitative issues quantitatively, and AHP (analytic hierarchy process) is used to quantify expert's subjective judgment. The assessment model is established based on the fuzzy AHP. The weight of each index is determined through the AHP and the degree of membership of each index through the fuzzy assessment method to obtain the fuzzy synthetic assessment matrix. Finally, a case study is conducted to verify the rationality and practicability of the assessment system and the proposed assessment method. PMID:25530756

The public health response to 'do-it-yourself' urbanism.

PubMed

Sibbald, Shannon L; Graham, Ross; Gilliland, Jason

2017-09-01

Greater understanding of the important and complex relationship between the built environment and human health has made 'healthy places' a focus of public health and health promotion. While current literature concentrates on creating healthy places through traditional decision-making pathways (namely, municipal land use planning and urban design processes), this paper explores do-it-yourself (DIY) urbanism: a movement circumventing traditional pathways to, arguably, create healthy places and advance social justice. Despite being aligned with several health promotion goals, DIY urbanism interventions are typically illegal and have been categorized as a type of civil disobedience. This is challenging for public health officials who may value DIY urbanism outcomes, but do not necessarily support the means by which it is achieved. Based on the literature, we present a preliminary approach to health promotion decision-making in this area. Public health officials can voice support for DIY urbanism interventions in some instances, but should proceed cautiously.

Few studies examine urban air pollution in sub-Saharan Africa (SSA), yet urbanization rates there are among the highest in the world. In this study, we measured 8-hr average occupational exposure levels of fine particulate matter (PM2.5), black carbon (BC), ultra violet active-particulate matter (UV-PM), and trace elements for individuals who worked along roadways in Nairobi, specifically bus drivers, garage workers, street vendors, and women who worked inside informal settlements. We found BC and re-suspended dust were important contributors to PM2.5 levels for all study populations, particularly among bus drivers, while PM2.5 exposure levels for garage workers, street vendors, and informal settlement residents were not statistically different from each other. We also found a strong signal for biomass emissions and trash burning, which is common in Nairobi’s low-income areas and open-air garages. These results suggest that the large portion of urban residents in SSA who walk along roadways would benefit from air quality regulations targeting roadway emissions from diesel vehicles, dust, and trash burning. This is the first study to measure occupational exposure to urban air pollution in SSA and results imply that roadway emissions are a serious public health concern. PMID:26034383

Gray, Jeremy P.; Campagna, Frank

2011-05-01

In the field of military Unmanned Ground Vehicles (UGV's), military units are forced to sweep largely populated cities and towns in search of hostile enemies. These urban types of operations are referred to as MOUT (Military Operations on Urban Terrain). During urban operations, these UGV's encounter difficulties when opening doors. Current manipulator end effectors have these difficulties, because they are not designed to mimic human hand operations. This paper explains the mechanical nature of the Modular Universal Door Opening End-effector (MUDOE). MUDOE is a result of our development research to improve robotic manipulators ability to negotiate closed doors. The presented solution has the ability to mimic human hand characteristics when opening doors. The end-effector possesses an ability to maintain a high Degree of Freedom (DoF), and grasp the doorknob by applying equally distributed forces to all points of contact.

Ancient water and sanitation systems - applicability for the contemporary urban developing world.

Bond, T; Roma, E; Foxon, K M; Templeton, M R; Buckley, C A

2013-01-01

The idea of implementing ancient water and wastewater technologies in the developing world is a persuasive one, since ancient systems had many features which would constitute sustainable and decentralised water and sanitation (WATSAN) provision in contemporary terminology. Latest figures indicate 2.6 billion people do not use improved sanitation and 1.1 billion practise open defecation, thus there is a huge need for sustainable and cost-effective WATSAN facilities, particularly in cities of the developing world. The objective of this study was to discuss and evaluate the applicability of selected ancient WATSAN systems for the contemporary developing world. Selected WATSAN systems in ancient Mesopotamia, the Indus Valley, Egypt, Greece, Rome and the Yucatan peninsula are briefly introduced and then discussed in the context of the developing world. One relevant aspect is that public latrines and baths were not only a part of daily life in ancient Rome but also a focal point for socialising. As such they would appear to represent a model of how to promote use and acceptance of modern community toilets and ablution blocks. Although public or community toilets are not classified as improved sanitation by WHO/UNICEF, this is a debatable premise since examples such as Durban, South Africa, illustrate how community toilets continue to represent a WATSAN solution for urban areas with high population density. Meanwhile, given the need for dry sanitation technologies, toilets based on the production of enriched Terra Preta soil have potential applications in urban and rural agriculture and warrant further investigation.

Identifying Societal Preferences for River Restoration in a Densely Populated Urban Environment: Evidence from a Discrete Choice Experiment in Central Brussels

2017-08-01

One of the major challenges facing river restoration in densely populated urban areas has been the disparity between the expectations of policy-makers and societal preferences. This study aimed to elicit public preferences and elucidate underlying sources of preference heterogeneity, using the Zenne River in central Brussels, Belgium, as a case study. A discrete choice experiment was administered to a representative sample of the Brussels population. Five attributes were specified, including water quality, ecological status, hydromorphological features of channels, recreational opportunities, and monetary cost. Our econometric analysis based on mixed logit models revealed that overall public would like to have a more natural river (open and naturalized channel, good water quality, and with rich species diversity), while achieving good water quality was the most preferred attribute. Respondents categorized as male, non-Belgian citizen, or not being a member of an environmental organization constituted an inclination to prefer the status quo. Belgian citizens showed a pronounced preference for good biodiversity, and being a member of an environmental organization could moderate the strong preference for good water quality. This study provided insights into the relative attractiveness of key attributes pertaining to river restoration, in general, and served as a useful input to the ongoing discussion concerning the future plan for the Zenne River in Brussels, specifically. Possible implications also exist for other urban river restorations in the rest of Europe, where the Water Framework Directive has become a major impetus for the expansion of freshwater ecosystem restoration from rural and peri-urban areas to densely populated urban areas. Particularly, the cultural heterogeneity of societal preferences should be tested and accounted for to compare the welfare impacts of river restoration and to facilitate benefit transfer, within and between river basins, in the Water Framework Directive implementation.

Mapping social values for urban green spaces using Public Participation GIS: the influence of spatial scale and implications for landscape planning.

NASA Astrophysics Data System (ADS)

Ives, Christopher

2015-04-01

Measuring social values for landscapes is an emerging field of research and is critical to the successful management of urban ecosystems. Green open space planning has traditionally relied on rigid standards and metrics without considering the physical requirements of green spaces that are valued for different reasons and by different people. Relating social landscape values to key environmental variables provides a much stronger evidence base for planning landscapes that are both socially desirable and environmentally sustainable. This study spatially quantified residents' values for green space in the Lower Hunter Valley of New South Wales, Australia by enabling participants to mark their values for specific open spaces on interactive paper maps. The survey instrument was designed to evaluate the effect of spatial scale by providing maps of residents' local area at both suburb and municipality scales. The importance of open space values differed depending on whether they were indicated via marker dots or reported on in a general aspatial sense. This suggests that certain open space functions were inadequately provided for in the local area (specifically, cultural significance and health/therapeutic value). Additionally, all value types recorded a greater abundance of marker dots at the finer (suburb) scale compared to the coarser (municipality) scale, but this pattern was more pronounced for some values than others (e.g. physical exercise value). Finally, significant relationships were observed between the abundance of value marker dots in parks and their environmental characteristics (e.g. percentage of vegetation). These results have interesting implications when considering the compatibility between different functions of green spaces and how planners can incorporate information about social values with more traditional approaches to green space planning.

Insular pathways to health care in the city: a multilevel analysis of access to hospital care in urban Kerala, India.

To identify individual and urban unit characteristics associated with access to inpatient care in public and private sectors in urban Kerala, and to discuss policy implications of inequalities in access. We analysed the NSSO survey (1995-1996) for urban Kerala with regard to source and trajectories of hospitalization. Multinomial multilevel regression models were built for 695 cases nested in 24 urban units. Private sector accounts for 62% of hospitalizations. Only 31% of hospitalizations are in free wards and 20% of public hospitalizations involve payment. Hospitalization pathways suggest a segmentation of public and private health markets. Members of poor and casual worker households have lower propensity of hospitalization in paying public wards or private hospitals. There were important variations between cities, with higher odds of private hospitalization in towns with fewer hospital beds overall and in districts with high private-public bed ratios. Cities from districts with better economic indicators and dominance of private services have higher proportion of private hospitalizations. The private sector is the predominant source of inpatient care in urban Kerala. The public sector has an important role in providing access to care for the poor. Investing in the quality of public services is essential to ensure equity in access.

"It was fun, it was dangerous": Heroin, young urbanities and opening reforms in China's borderlands.

PubMed

Zoccatelli, Giulia

2014-07-01

An unprecedented flow of opiates flooded China's southern regions in the wake of the country's opening reforms in the 1980s. After the Maoist war on drugs had turned the People's Republic of China into an almost entirely drug-free area for three decades, heroin reappeared to become the most widely used illicit substance in the country. As the number of users rose by 1200% between 1988 and 1998, a generation of young people found themselves facing the consequences of addiction. Based on ethnographic data collected during 13 months of field research among a community of heroin users in the county-level city of Qilin in Yunnan Province, this paper explores the interplay of historical and social factors that led southern China's young urbanities to turn to heroin in the 1980s and 1990s. Towards this end, it draws on a broad array of research methods including the collection of life histories, extensive participant observation, and focus groups among the members of Qilin's local community of heroin users. I argue that the spread of heroin among southern China's young urbanities should be read as the aggregate outcome of such seemingly disparate factors as the opening of new global routes for the trafficking of opiates, the almost complete lack of Chinese public discourse around drugs in the immediate post-Mao period, the increased individualization of young people's ambitions, desires and forms of socialization, and the rise of a consumerist market economy in the country. Based on the data collected, I claim that the boom in the diffusion of heroin use in post-reform China cannot be described exclusively as a matter of deviant individual behaviours. Rather, it has to be interpreted as a complex social act, which is only understandable when framed within the social and historical context in which it was performed. Copyright © 2014 Elsevier B.V.

Traffic-related air pollution in urban areas contributes significantly to commuters' daily PM2.5 exposures, but varies widely depending on mode of commuting. To date, studies show conflicting results for PM2.5 exposures based on mode of commuting, and few studies compare multiple modes of transportation simultaneously along a common route, making inter-modal comparisons difficult. In this study, we examined breathing zone PM2.5 exposures for six different modes of commuting (bicycle, walking, driving with windows open and closed, bus, and light-rail train) simultaneously on a single 2.7 km (1.68 mile) arterial urban route in Salt Lake City, Utah (USA) during peak "rush hour" times. Using previously published minute ventilation rates, we estimated the inhaled dose and exposure rate for each mode of commuting. Mean PM2.5 concentrations ranged from 5.20 μg/m3 for driving with windows closed to 15.21 μg/m3 for driving with windows open. The estimated inhaled doses over the 2.7 km route were 6.83 μg for walking, 2.78 μg for cycling, 1.28 μg for light-rail train, 1.24 μg for driving with windows open, 1.23 μg for bus, and 0.32 μg for driving with windows closed. Similarly, the exposure rates were highest for cycling (18.0 μg/hr) and walking (16.8 μg/hr), and lowest for driving with windows closed (3.7 μg/hr). Our findings support previous studies showing that active commuters receive a greater PM2.5 dose and have higher rates of exposure than commuters using automobiles or public transportation. Our findings also support previous studies showing that driving with windows closed is protective against traffic-related PM2.5 exposure.

Traffic-related air pollution in urban areas contributes significantly to commuters’ daily PM2.5 exposures, but varies widely depending on mode of commuting. To date, studies show conflicting results for PM2.5 exposures based on mode of commuting, and few studies compare multiple modes of transportation simultaneously along a common route, making inter-modal comparisons difficult. In this study, we examined breathing zone PM2.5 exposures for six different modes of commuting (bicycle, walking, driving with windows open and closed, bus, and light-rail train) simultaneously on a single 2.7 km (1.68 mile) arterial urban route in Salt Lake City, Utah (USA) during peak “rush hour” times. Using previously published minute ventilation rates, we estimated the inhaled dose and exposure rate for each mode of commuting. Mean PM2.5 concentrations ranged from 5.20 μg/m3 for driving with windows closed to 15.21 μg/m3 for driving with windows open. The estimated inhaled doses over the 2.7 km route were 6.83 μg for walking, 2.78 μg for cycling, 1.28 μg for light-rail train, 1.24 μg for driving with windows open, 1.23 μg for bus, and 0.32 μg for driving with windows closed. Similarly, the exposure rates were highest for cycling (18.0 μg/hr) and walking (16.8 μg/hr), and lowest for driving with windows closed (3.7 μg/hr). Our findings support previous studies showing that active commuters receive a greater PM2.5 dose and have higher rates of exposure than commuters using automobiles or public transportation. Our findings also support previous studies showing that driving with windows closed is protective against traffic-related PM2.5 exposure. PMID:29121096

The effects of urban conditions on tree growth have been investigated in an increasing number of studies over the last decades, emphasizing the harsh environment of cities. Urban trees often grow in highly paved, compacted sites with consequently less soil moisture, higher soil temperatures, and greater vapor pressure deficits. However, there is still a knowledge gap regarding the impact of harsh paved environments on urban tree growth during drought years on the growth patterns of urban trees. The present study investigated the structure and growth of the common urban tree species small-leaved lime (Tilia cordata) at a highly paved public square (CPS) compared with a contrasting more open, greener square (OGS). Continuously, measured high precision dendrometer data along with meteorological data of the extreme dry and warm summer 2015 as well as dendrochronological data of the sampled trees were investigated to analyze tree growth during a drought year. The results highlight different tree dimensions and growth patterns of the trees at both sites, influenced by tree age and distinct site conditions. While the trees at OGS grew up to 2.5 mm from July until mid of August, the trees at CPS had only 0.4-mm diameter increment. After the initial expansion at CPS, tree diameter contracted again during summer to the point of shrinkage (up to 0.8 mm) at the end of our investigation. Further drought year analysis confirmed the patterns of significant stem growth reductions in the consecutive two years following the drought. A correlation analysis revealed that transpiration, air temperature, and vapor pressure deficit were negatively correlated with the daily diameter growth, whereas precipitation had a strong positive effect. Due to high transpiration rates associated with anisohydric water use behavior, T. cordata was able to provide evaporative cooling even during drought. However, this anisohydric behavior resulted in substantial growth decline afterwards especially at paved sites like CPS. Our results suggest selection of tree species, such as those with isohydric water use behavior, which may achieve a better balance between growth, transpiration, and hence evaporative cooling.

Currently more and more people concerned about the safety of major public security. Public participant urban infrastructure safety monitoring and investigation has become a trend in the era of big data. In this paper, public participant urban infrastructure safety protection system based on smart phones is proposed. The system makes it possible to public participant disaster data collection, monitoring and emergency evaluation in the field of disaster prevention and mitigation. Function of the system is to monitor the structural acceleration, angle and other vibration information, and extract structural deformation and implement disaster emergency communications based on smartphone without network. The monitoring data is uploaded to the website to create urban safety information database. Then the system supports big data analysis processing, the structure safety assessment and city safety early warning.

Measures affecting traffic flows in urban areas, e.g. changing the configuration of traffic lights, are often causing emotional debates by citizens who are affected by these measures. Up to now, citizens are usually not involved in traffic planning and the evaluation of the decisions that were taken. The enviroCar project provides an open platform for collecting and analyzing car sensor data with GPS position data. On the hardware side, enviroCar relies on using Android smartphones and OBD-II Bluetooth adapters. A Web server component collects and aggregates the readings from the cars, anonymizes them and publishes the data as open data which scientists, public administrations or other third parties can utilize for further analysis. In this work, we provide a general overview on the enviroCar project and present a project in a mid-size city in Germany. The city's administration utilized the enviroCar platform with the help of a traffic system consultancy for including citizens in the evaluation process of different traffic light configurations along major traffic axes. Therefore, a public campaign was started including local workshops to engage the citizens. More than 150 citizens were actively collecting more about 9.500 tracks including about 2.5 million measurements. Dedicated evaluation results for the different traffic axes were computed based on the collected data set. Because the data is publicly available as open data, others may prove and reproduce the evaluation results contributing to an objective discussion of traffic planning measures. In summary, the project illustrates how Citizen Science methods and technologies improve traffic planning and related discussions.

Conservation in metropolitan regions: assessing trends and threats of urban development and climate change

Two global challenges to successful conservation are urban expansion and climate change. Rapid urban growth threatens biodiversity and associated ecosystem services, while climate change may make currently protected areas unsuitable for species that exist within them. We examined three measures of landscape change for 8800 km2 of the San Francisco Bay metropolitan region over 80 years past and future: urban growth, protected area establishment, and natural vegetation type extents. The Bay Area is a good test bed for conservation assessment of the impacts of temporal and spatial of urban growth and land cover change. The region is geographically rather small, with over 40% of its lands already dedicated to protected park and open space lands, they are well-documented, and, the area has had extensive population growth in the past and is projected to continue to grow. The ten-county region within which our study area is a subset has grown from 1.78 million people in 1930, to 6.97 million in 2000 and is estimated to grow to 10.94 million by 2050. With such an influx of people into a small geographic area, it is imperative to both examine the past urban expansion and estimate how the future population will be accommodated into the landscape. We quantify these trends to assess conservation 'success' through time. We used historical and current landcover maps to assess trend, and a GIS-based urban modeling (UPlan) to assess future urban growth impacts in the region, under three policy scenarios- business as usual, smart growth, and urban redevelopment. Impacts are measured by the amount of open space targeted by conservation planners in the region that will be urbanized under each urban growth policy. Impacts are also measured by estimates of the energy consumption projected for each of the scenarios on household and business unit level. The 'business as usual' and 'smart growth' scenarios differed little in their impacts to targeted conservation lands, because so little open space remains to accommodate the expected population growth. Redevelopment conserved more naturally vegetated open space. The redevelopment scenario also permits the lowest increase in energy demand because buildings taken out in the process are reconfigured to higher levels of energy efficiency. However, redevelopment requires substantial increases in residential densities to confine the spatial footprint of the expected future urban growth. These three urban growth scenario footprints differ in their impact to natural vegetation and open space. To incorporate the influence of climate change on remaining natural ecosystems in this urbanizing landscape, we projected the stability of existing, mapped, vegetation types in the region under future climates by examining where projected ranges of the dominant plant species comprising each California Wildlife Habitat Relationship type will all remain together, and where they will begin to dis-associate due to biogeographic response to changing climate. This permits identification of stable and unstable zones of vegetation. The combination of climate stable, high conservation priority and likelihood of urban development provides a way to prioritize conservation land acquisitions.

Summer in the City - Assessing and Communicating the Richmond, VA Urban Heat Island to the Public and Policymakers

The local impacts of global climate change are generally underestimated or misunderstood by the public and policymakers as far-off, future problems. However, differential and regional surface warming trends are exacerbated in urban areas due to the radiative properties of impervious surfaces like buildings and roads relative to natural landscapes. Decades of research illustrate that this unnatural radiative imbalance in the built environment gives rise to the well-studied urban heat island effect, whereby air temperatures in urban areas are several degrees warmer than in surrounding non-urbanized areas. In this way, the urban heat island effect presents a unique opportunity to highlight the human influence on Earth systems and at the same time mobilize local community-scale action to mitigate and become resilient to climate change impacts on tangible, experiential time scales. However, public stakeholders, city planners, and policymakers may view the urban heat island effect and its mitigation strategies through varying degrees of climatological, public health, and urban development knowledge and interest. This variation in stakeholder engagement highlights the need for individualized science communication strategies for each audience in order to maximize understanding of the scientific outcomes and tactics for mitigating the urban heat island effect. The City of Richmond, Virginia is currently developing a climate action plan as part of their greenhouse gas emission reduction initiative, RVAgreen 2050, and its recently announced "Richmond 300," a 20-year city development master plan. These initiatives provide the policy backdrop for a public and stakeholder education campaign centered on communicating urban heat island effects and resilience strategies. As such, the Science Museum of Virginia led the city's first urban heat island assessment using citizen science and leveraging a network of local university, non-profit, and city government stakeholders. Here, we will share our tactics for public- and policymaker-centered dissemination of urban heat island science, findings, and mitigation strategies using a variety of techniques including local news stations, 3D visualization technology, NOAA-funded museum media pieces, and policymaker/stakeholder engagement opportunities.

2013-01-01

With increasing interest in the use of urban green space to promote human health, there is a need to understand the extent to which park users conceptualize these places as a resource for health and well-being. This study sought to examine park users’ own reasons for and benefits from green space usage and compare these with concepts and constructs in existing person-environment-health theories and models of health. Conducted in 13 public green spaces in Sheffield, UK, we undertook a qualitative content analysis of 312 park users’ responses to open-ended interview questions and identified a breadth, depth and salience of visit motivators and derived effects. Findings highlight a discrepancy between reasons for visiting and derived effects from the use of urban green space. Motivations emphasized walking, green space qualities, and children. Derived effects highlighted relaxation, positive emotions within the self and towards the place, and spiritual well-being. We generate a taxonomy of motivations and derived effects that could facilitate operationalization within empirical research and articulate a conceptual framework linking motivators to outcomes for investigating green space as a resource for human health and well-being.

Children's active free play in local neighborhoods: a behavioral mapping study.

PubMed

Veitch, J; Salmon, J; Ball, K

2008-10-01

Many Australian children are more sedentary than they should be, and almost one in five are currently overweight or obese. Some children may face difficulties finding opportunities to be active, having poor access to safe public open spaces or having low independent mobility limiting their access to places to play. This study aimed to examine children's access to places in their neighborhood for active free play and how these vary by age, sex and socioeconomic status (SES). Behavioral maps of the local neighborhood were completed by children (8-12 years) from five primary schools across different areas of Melbourne. Children living in low SES outer-urban neighborhoods had to travel greater distances to access local parks compared with those in inner-urban mid and high SES areas. One-third (32%) of children reported an independent mobility range of <100 m from home. In conclusion, for some children opportunities to engage in active free play in the local neighborhood may be limited due to lack of parks in close proximity to home and restricted independent mobility. It is important to collaborate with local governments, urban planners and community groups to improve access to neighborhood parks and to promote a sense of neighborhood safety.

Adopting public values and climate change adaptation strategies in urban forest management: A review and analysis of the relevant literature.

PubMed

Ordóñez Barona, Camilo

2015-12-01

Urban trees are a dominant natural element in cities; they provide important ecosystem services to urban citizens and help urban areas adapt to climate change. Many rationales have been proposed to provide a purpose for urban forest management, some of which have been ineffective in addressing important ecological and social management themes. Among these rationales we find a values-based perspective, which sees management as a process where the desires of urban dwellers are met. Another perspective is climate change adaptation, which sees management as a process where urban forest vulnerability to climate change is reduced and resilience enhanced. Both these rationales have the advantage of complementing, enhancing, and broadening urban forest management objectives. A critical analysis of the literature on public values related to urban forests and climate change adaptation in the context of urban forests is undertaken to discuss what it means to adopt these two issues in urban forest management. The analysis suggests that by seeing urban forest management as a process by which public values are satisfied and urban-forest vulnerabilities to climate change are reduced, we can place issues such as naturalization, adaptive management, and engaging people in management at the centre of urban forest management. Focusing urban forest management on these issues may help ensure the success of programs focused on planting more trees and increasing citizen participation in urban forest management.

UV Radiation in an Urban Canyon in Southeast Queensland

McKinley, A. R.; Moore, M. R.; Kimlin, M. G.

2006-12-01

Ultraviolet radiation (UV) has the possibility to both harm and to benefit human beings when unprotected exposure occurs. After receiving small amounts of UV our bodies begin to synthesise vitamin D, which is essential for maintaining healthy bones, however excessive UV exposure can result in a variety of damaging outcomes ranging from sunburn to skin cancer and cataracts. For this reason it is very important to understand the different environments in which people encounter UV so as to better prepare the public to make smart and healthy sun exposure decisions. Each day more and more people are moving into large cities around the world and spending their time inside the urban canyon, however UV measurements are generally taken at scientific stations in open areas or on top of tall buildings, meaning that at times the environmental characteristics measured may not accurately represent those found at street-level in these highly urbanized areas. Urban canyons are home to both very tall buildings and tropospheric air pollution, each of which reduces the amount of UV reaching street-level. This study measured the varying difference between UV measurements taken at street-level and at a standard UV monitoring site on top of a building outside of the urban canyon. Investigation was conducted in the central business district (CBD) of Brisbane, Australia, which models the CBDs of large cities around the world in that it boasts a great number of tall buildings, including many skyscrapers. Data was collected under clear sky conditions at five different street-level sites in the CBD (on either side of two streets running perpendicular to one another (four sites) and in a public square) and then compared to that obtained on the same day at the Queensland University of Technology's Australian Sun and Health Research Laboratory (ASHRL), which is located 2.5 kilometres outside Brisbane's CBD. Minimum erythemal dose (MED) data was collected at each location and it was found that throughout the day the intensity of erythemal UV measured in the city was significantly lower than that measured at the ASHRL site. On average the amount of erythemal UV measured in the urban canyon was approximately 33% of that measured at the ASHRL site. Based upon these findings we hope to conduct further study regarding UV exposure in the urban canyon.

Quality Analysis of Open Street Map Data

Crowd sourcing geographic data is an opensource geographic data which is contributed by lots of non-professionals and provided to the public. The typical crowd sourcing geographic data contains GPS track data like OpenStreetMap, collaborative map data like Wikimapia, social websites like Twitter and Facebook, POI signed by Jiepang user and so on. These data will provide canonical geographic information for pubic after treatment. As compared with conventional geographic data collection and update method, the crowd sourcing geographic data from the non-professional has characteristics or advantages of large data volume, high currency, abundance information and low cost and becomes a research hotspot of international geographic information science in the recent years. Large volume crowd sourcing geographic data with high currency provides a new solution for geospatial database updating while it need to solve the quality problem of crowd sourcing geographic data obtained from the non-professionals. In this paper, a quality analysis model for OpenStreetMap crowd sourcing geographic data is proposed. Firstly, a quality analysis framework is designed based on data characteristic analysis of OSM data. Secondly, a quality assessment model for OSM data by three different quality elements: completeness, thematic accuracy and positional accuracy is presented. Finally, take the OSM data of Wuhan for instance, the paper analyses and assesses the quality of OSM data with 2011 version of navigation map for reference. The result shows that the high-level roads and urban traffic network of OSM data has a high positional accuracy and completeness so that these OSM data can be used for updating of urban road network database.

Beyond urban penalty and urban sprawl: back to living conditions as the focus of urban health.

PubMed

Freudenberg, Nicholas; Galea, Sandro; Vlahov, David

2005-02-01

Researchers have long studied urban health, both to describe the consequences of urban living and to design interventions to promote the health of people living in cities. Two approaches to understanding the impact of cities on health have been dominant, namely, urban health penalty and urban sprawl. The urban penalty approach posits that cities concentrate poor people and expose them to unhealthy physical and social environments. Urban sprawl focuses on the adverse health and environmental effects of urban growth into outlying areas. We propose a model that integrates these approaches and emphasizes urban living conditions as the primary determinant of health. The aim of the model is to move beyond describing the health-related characteristics of various urban populations towards identifying opportunities for intervention. Such a shift in framework enables meaningful comparisons that can inform public health activities at the appropriate level and evaluate their effectiveness in improving the health of urban populations. The model is illustrated with two examples from current urban public health practice.

R package CityWaterBalance | Science Inventory | US EPA

EPA Pesticide Factsheets

CityWaterBalance provides a reproducible workflow for studying an urban water system. The network of urban water flows and storages can be modeled and visualized. Any city may be modeled with preassembled data, but data for US cities can be gathered via web services using this package and dependencies, geoknife and dataRetrieval. Urban water flows are difficult to comprehensively quantify. Although many important data sources are openly available, they are published by a variety of agencies in different formats, units, spatial and temporal resolutions. Increasingly, open data are made available via web services, which allow for automated, current retrievals. Integrating data streams and estimating the values of unmeasured urban water flows, however, remains needlessly time-consuming. In order to streamline a reproducible analysis, we have developed the CityWaterBalance package for the open source R language. The CityWaterBalance package for R is based on a simple model of the network of urban water flows and storages. The model may be run with data that has been pre-assembled by the user, or data can be retrieved by functions in CityWaterBalance and dependencies. CityWaterBalance can be used to quickly assemble a quantitative portrait of any urban water system. The systemic effects of water management decisions can be readily explored. Much of the data acquisition process for US cities can already be automated, while the package serves as a place-hold

Assessment of the urban water system with an open ...

EPA Pesticide Factsheets

Urban water systems convey complex environmental and man-made flows. The relationships among water flows and networked storages remains difficult to comprehensively evaluate. Such evaluation is important, however, as interventions are designed (e.g, conservation measures, green infrastructure) to modify specific flows of urban water (e.g. drinking water, stormwater) that may have systemic effects. We have developed a general model that specifies the relationships among urban water system components, and a set of tools for evaluating the model for any city as the R package CityWaterBalance. CityWaterBalance provides a reproducible workflow for assessing urban water system(s) by facilitating the retrieval of open data, largely via web services, and analysis of these data using open-source R functions. It allows the user to 1) quickly assemble a quantitative, unified picture of flows thorough an urban area, and 2) easily change the spatial and temporal boundaries of analysis to match scales relevant to local decision-making. We used CityWaterBalance to evaluate the water system in the Chicago metropolitan area on a monthly basis for water years 2001-2010. Results, including the relative magnitudes and temporal variability of major water flows in greater Chicago, are used to consider 1) trade-offs associated with management alternatives for stormwater and combined sewer overflows and 2) the significance of future changes in precipitation, which is the largest

Internationally, the importance of a coordinated effort to protect both biodiversity and public health is more and more recognized. These issues are often concentrated or particularly challenging in urban areas, and therefore on-going urbanization worldwide raises particular issues both for the conservation of living natural resources and for population health strategies. These challenges include significant difficulties associated with sustainable management of urban ecosystems, urban development planning, social cohesion and public health. An important element of the challenge is the need to interface between different forms of knowledge and different actors from science and policy. We illustrate this with examples from Belgium, showcasing concrete cases of human-nature interaction. To better tackle these challenges, since 2011, actors in science, policy and the broader Belgian society have launched a number of initiatives to deal in a more integrated manner with combined biodiversity and public health challenges in the face of ongoing urbanization. This emerging community of practice in Belgium exemplifies the importance of interfacing at different levels. (1) Bridges must be built between science and the complex biodiversity/ecosystem-human/public health-urbanization phenomena. (2) Bridges between different professional communities and disciplines are urgently needed. (3) Closer collaboration between science and policy, and between science and societal practice is needed. Moreover, within each of these communities closer collaboration between specialized sections is needed.

2009-10-01

Spatial visibility analysis is the important direction of pedestrian behaviors because our visual conception in space is the straight method to get environment information and navigate your actions. Based on the agent modeling and up-tobottom method, the paper develop the framework about the analysis of the pedestrian flow depended on visibility. We use viewshed in visibility analysis and impose the parameters on agent simulation to direct their motion in urban space. We analyze the pedestrian behaviors in micro-scale and macro-scale of urban open space. The individual agent use visual affordance to determine his direction of motion in micro-scale urban street on district. And we compare the distribution of pedestrian flow with configuration in macro-scale urban environment, and mine the relationship between the pedestrian flow and distribution of urban facilities and urban function. The paper first computes the visibility situations at the vantage point in urban open space, such as street network, quantify the visibility parameters. The multiple agents use visibility parameters to decide their direction of motion, and finally pedestrian flow reach to a stable state in urban environment through the simulation of multiple agent system. The paper compare the morphology of visibility parameters and pedestrian distribution with urban function and facilities layout to confirm the consistence between them, which can be used to make decision support in urban design.

The study investigated the influence of selected husbandry factors on interval to resumption of post-partum cyclicity among dairy cows in urban and peri-urban Kampala. A prospective study of 85 day post-partum period of 59 dairy cows in open (n = 38) and zero grazing (n = 21) systems was conducted on 24 farms. Cows of parity 1-6 were recruited starting 15-30 days post-partum. Progesterone (P4) content in milk taken at 10-12 day intervals was analysed using ELISA. The cow P4 profiles were classified into 'normal' (< 56 days), 'delayed' (> 56 days), 'ceased' or 'prolonged' (if started < 56 days but with abnormal P4 displays) resumption of luteal activity and tested for association with husbandry and cow factors. Of the 59 cows, luteal activity in 81.4% resumed normally and in 18.6%, delayed. Only 23.7% maintained regular luteal activity, while the others had ceased (10.2%), prolonged (37.3%) or unclear luteal activity (20.3%). There were no differences between open and zero-grazed cows. Milk production was higher (p < 0.05) in zero than open grazing, in urban than peri-urban and in cows fed on brew waste (p < 0.001) compared with mill products and banana peels. Results suggest that luteal activity resumes normally in a majority of cows, although only a minority experienced continued normal cyclicity once ovulation had occurred, in the two farming systems irrespective of feed supplements or water, and that supplementing with brew waste is beneficial for milk production. © 2014 The Authors.

Brovelli, Maria Antonia; Minghini, Marco; Zamboni, Giorgio

2016-04-01

Driven by the recent trends in the GIS domain including Volunteered Geographic Information, geo-crowdsourcing and citizen science, and fostered by the constant technological advances, collection and dissemination of geospatial information by ordinary people has become commonplace. However, applications involving user-generated geospatial content show dramatically diversified patterns in terms of incentive, type and level of participation, purpose of the activity, data/metadata provided and data quality. This study contributes to this heterogeneous context by investigating public participation in GIS within the field of mobile-based applications. Results not only show examples of how to technically build GIS applications enabling user collection and interaction with geospatial data, but they also draw conclusions about the methods and needs of public participation. We describe three projects with different scales and purposes in the context of urban monitoring and planning, and tourism valorisation. In each case, an open source architecture is used, allowing users to exploit their mobile devices to collect georeferenced information. This data is then made publicly available on specific Web viewers. Analysis of user involvement in these projects provides insights related to participation patterns which suggests some generalized conclusions.

Smart governance for smart city

Mutiara, Dewi; Yuniarti, Siti; Pratama, Bambang

2018-03-01

Some of the local government in Indonesia claimed they already created a smart city. Mostly the claim based of IT utilization for their governance. In general, a smart city definition is to describe a developed urban area that creates sustainable economic development and high quality of life by excelling in multiple key; economy, mobility, environment, people, living, and government. For public services, the law guarantees good governance by setting the standard for e-government implicitly including for local government or a city. Based on the arguments, this research tries to test the condition of e-government of the Indonesian city in 34 provinces. The purpose is to map e-government condition by measuring indicators of smart government, which are: transparent governance and open data for the public. This research is departing from public information disclosure law and to correspond with the existence law. By examining government transparency, the output of the research can be used to measure the effectiveness of public information disclosure law and to determine the condition of e-government in local government in which as part of a smart city.

A framework for air quality monitoring based on free public data and open source tools

NASA Astrophysics Data System (ADS)

Nikolov, Hristo; Borisova, Denitsa

2014-10-01

In the recent years more and more widely accepted by the Space agencies (e.g. NASA, ESA) is the policy toward provision of Earth observation (EO) data and end products concerning air quality especially in large urban areas without cost to researchers and SMEs. Those EO data are complemented by increasing amount of in-situ data also provided at no cost either from national authorities or having crowdsourced origin. This accessibility together with the increased processing capabilities of the free and open source software is a prerequisite for creation of solid framework for air modeling in support of decision making at medium and large scale. Essential part of this framework is web-based GIS mapping tool responsible for dissemination of the output generated. In this research an attempt is made to establish a running framework based solely on openly accessible data on air quality and on set of freely available software tools for processing and modeling taking into account the present status quo in Bulgaria. Among the primary sources of data, especially for bigger urban areas, for different types of gases and dust particles, noted should be the National Institute of Meteorology and Hydrology of Bulgaria (NIMH) and National System for Environmental Monitoring managed by Bulgarian Executive Environmental Agency (ExEA). Both authorities provide data for concentration of several gases just to mention CO, CO2, NO2, SO2, and fine suspended dust (PM10, PM2.5) on monthly (for some data on daily) basis. In the framework proposed these data will complement the data from satellite-based sensors such as OMI instrument aboard EOS-Aura satellite and from TROPOMI instrument payload for future ESA Sentinel-5P mission. Integral part of the framework is the modern map for the land use/land cover which is provided from EEA by initiative GIO Land CORINE. This map is also a product from EO data distributed at European level. First and above all, our effort is focused on provision to the wider public living in urbanized areas with one reliable source of information on the present conditions concerning the air quality. Also this information might be used as indicator for presence of acid rains in agriculture areas close to industrial or electricity plants. Its availability at regular basis makes such information valuable source in case of manmade industrial disasters or incidents such as forest fires. Key issue in developing this framework is to ensure the delivery of reliable data products related to air quality at larger scale that those available at the moment.

Policy, Research and Residents' Perspectives on Built Environments Implicated in Heart Disease: A Concept Mapping Approach.

Stankov, Ivana; Howard, Natasha J; Daniel, Mark; Cargo, Margaret

2017-02-09

An underrepresentation of stakeholder perspectives within urban health research arguably limits our understanding of what is a multi-dimensional and complex relationship between the built environment and health. By engaging a wide range of stakeholders using a participatory concept mapping approach, this study aimed to achieve a more holistic and nuanced understanding of the built environments shaping disease risk, specifically cardiometabolic risk (CMR). Moreover, this study aimed to ascertain the importance and changeability of identified environments through government action. Through the concept mapping process, community members, researchers, government and non-government stakeholders collectively identified eleven clusters encompassing 102 built environmental domains related to CMR, a number of which are underrepresented within the literature. Among the identified built environments, open space, public transportation and pedestrian environments were highlighted as key targets for policy intervention. Whilst there was substantive convergence in stakeholder groups' perspectives concerning the built environment and CMR, there were disparities in the level of importance government stakeholders and community members respectively assigned to pedestrian environments and street connectivity. These findings support the role of participatory methods in strengthening how urban health issues are understood and in affording novel insights into points of action for public health and policy intervention.

Gong, Peng; Liang, Song; Carlton, Elizabeth J; Jiang, Qingwu; Wu, Jianyong; Wang, Lei; Remais, Justin V

2013-01-01

China has seen the largest human migration in history, and the country's rapid urbanisation has important consequences for public health. A provincial analysis of its urbanisation trends shows shifting and accelerating rural-to-urban migration across the country and accompanying rapid increases in city size and population. The growing disease burden in urban areas attributable to nutrition and lifestyle choices is a major public health challenge, as are troubling disparities in health-care access, vaccination coverage, and accidents and injuries in China's rural-to-urban migrant population. Urban environmental quality, including air and water pollution, contributes to disease both in urban and in rural areas, and traffic-related accidents pose a major public health threat as the country becomes increasingly motorised. To address the health challenges and maximise the benefits that accompany this rapid urbanisation, innovative health policies focused on the needs of migrants and research that could close knowledge gaps on urban population exposures are needed.

Semantic Segmentation and Unregistered Building Detection from Uav Images Using a Deconvolutional Network

NASA Astrophysics Data System (ADS)

Ham, S.; Oh, Y.; Choi, K.; Lee, I.

2018-05-01

Detecting unregistered buildings from aerial images is an important task for urban management such as inspection of illegal buildings in green belt or update of GIS database. Moreover, the data acquisition platform of photogrammetry is evolving from manned aircraft to UAVs (Unmanned Aerial Vehicles). However, it is very costly and time-consuming to detect unregistered buildings from UAV images since the interpretation of aerial images still relies on manual efforts. To overcome this problem, we propose a system which automatically detects unregistered buildings from UAV images based on deep learning methods. Specifically, we train a deconvolutional network with publicly opened geospatial data, semantically segment a given UAV image into a building probability map and compare the building map with existing GIS data. Through this procedure, we could detect unregistered buildings from UAV images automatically and efficiently. We expect that the proposed system can be applied for various urban management tasks such as monitoring illegal buildings or illegal land-use change.

Statistical treatment of this data was firstly presented in a PhD Thesis ("Percepção sonora e térmica e avaliação de conforto em espaços urbanos abertos do município de Belo Horizonte - MG, Brasil" (Hirashima, 2014) [1]), providing relevant information on thermal conditions in these locations and on thermal comfort assessment. Up to now, this data was also explored in the article "Daytime Thermal Comfort in Urban Spaces: A Field Study in Brazil" (Hirashima et al., in press) [2]. These references are recommended for further interpretation and discussion.

[Physicians, prostitution, and venereal disease in Colombia (1886-1951)].

PubMed

Obregón, Diana

2002-01-01

The article examines the Colombian medical field's fight against so-called venereal diseases between 1886 and 1951, a period when the country was undergoing processes of urbanization, population growth, and the emergence both of industry as well as of a middle class and an urban proletariat. Physicians found a close connection between the spread of syphilis and gonorrhea and the rise of prostitution in cities. At the close of the 19th century, doctors and public health bodies assumed prostitution was inevitable. In 1907 they managed to have it legalized and they opened clinics to dispense mercury therapy and treatment with arsenic compounds. Starting in the 1930s amd 1940s, treatment of venereal diseases was viewed as the State's duty, necessary to protect "la raza" and safeguard progress and civilization. As of 1950, the efficient use of penicillin once again caused the question of prostitution to be posed in more moral and aesthetic terms and brought an end to the regulations groverning its practice, at least in Bogota.

Urban Conservation Policies and Plans for a World Heritage Site Case: Antique Pergamon City and its Multi-Layered Cultural Landscape

2017-10-01

Izmir’s Pergamon (Bergama) Antique City and Its Multi-Layered Cultural Landscape entered the UNESCO World Heritage List with the participation of 21 countries in the 38th World Heritage Committee Meeting held in Doha, Qatar’s capital in between 15 - 25 June 2014. Bergama became the 999th WORLD HERITAGE. Bergama, which has been in operation since 2010, has entered the list as a Multi-layered Cultural Landscape Area. The main purpose of this paper will explain and summarize of urban and archaeological conservation efforts for Pergamon since 1992 to 2014. In the paper also aimed to give the conservation policies of public administrations which mainly central /Ministry of Culture and Tourism, Ministry of Environment/ and local /Bergama Municipality, Gen. Directorate of Vakiflar. Turkey is one of the 10 original member states to establish UNESCO. 9 cities in Turkey are included in the UNESCO List of World Heritage Sites. Further, 23 sites have been nominated and are included in the tentative list. The activities aimed to include the district of Bergama in the UNESCO World Heritage List are ongoing in the years 2009-2014. All the efforts have been made carry this unique antique city to the UNESCO Heritage List at 2014. As an Urban Conservation Planner, I had a change of preparing the FIRST Conservation Aimed Plans and urban designs for Urban and Archaeological Sites of Pergamon together with my team, in the years between 1992-94. We prepared conservation aimed plans for all of the areas of Acropolis, Middle City and Ottoman period urban conservation areas. Urban and archaeological sites of Pergamon the ancient city today, which is over two thousand years old, where scientists, archaeologists, architects, art historians, urban planners, sculptors and similar arts and culture, men talk about admiration, write about and write praises, face to face some deterioration and destruction. As a conservation planner working on Pergamon since 1992, I’ will concentrate the following results and conclusions; 1. Urban and Archaeological Sites in Turkey are generally in danger of destruction because of lack of public awareness and lack of sufficient monetary funds and administrative organisations. 2. In the Case Pergamon; this problem mentioned above are already defeated by the local and central governmental bodies. Unfortunately this success costs time and money, as well as more losess in the urban and archaeological areas. Especially loss in old Ottoman Houses and open archaeological sites. 3. The Paper will be aim to handle the governmental policies about the conservation, the inefficiencies in planning and approval of conservation aimed plans.

Open Space between Residential Buildings as a Factor of Sustainable Development - Case Studies in Brno (Czech Republic) and Vienna (Austria)

NASA Astrophysics Data System (ADS)

Kilnarová, Pavla; Wittmann, Maxmilian

2017-12-01

The characteristics of open spaces between residential buildings have, as authors suppose, an impact on the sustainable development of urban areas. Spatial arrangement and accessibility of these spaces, the type and height of surrounding buildings, the quantity and character of greenery, and many more characteristics influence the quality of environment, and the quality of life of local residents. These and further characteristics of the open spaces between residential buildings influence the ecological stability of the area, its hygienic qualities, the intensity and way of using by various social groups, and also the prices of real estates. These qualities indicate the environmental, social and economic sustainability of the urban area. The proposed research methodology assessed specific indicators of sustainability within a range from 0 to 10 points. 5 points correspond to the general standard in the area, 0 points indicate degradation, and 10 points indicate the highest contribution to sustainable development. Observation methods, questionnaire survey, statistical analyses, and methods of measurement were used to determine the values of the given indicators. The paper analyses the impact of the open spaces between residential buildings on sustainability via the case studies performed in the Central European cities of Brno, Czech Republic and Vienna, Austria. Two forms of residential urban structures in the City of Brno in the Czech Republic were selected for the analysis: the closed courtyards in the urban block from the 19th century and the open spaces in the housing estates constructed under socialism in the 20th century. The question is, if the different forms of spaces between residential buildings influence the sustainability of urban area and satisfaction of inhabitants in different ways. A complementary case study in Vienna indicates that inhabitants of a housing estate in Vienna, as well as inhabitants of housing estates in Brno, highly appreciate the meaning of large green open spaces between buildings. The paper presents results of basic research. The results indicate that the sustainability of open housing estate forms is higher than the authors expected.

Public health, the APHA, and urban renewal.

Joint efforts by fields of public health in the last decade have advocated use of the built environment to protect health. Past involvement by public health advocates in urban policy, however, has had mixed results. Although public health has significantly contributed to health improvements, its participation in urban renewal activities was problematic. Health advocates and the American Public Health Association produced guidelines that were widely used to declare inner-city areas blighted and provided a scientific justification for demolishing neighborhoods and displacing mostly poor and minority people. Furthermore, health departments failed to uphold their legal responsibility to ensure that relocated families received safe, affordable housing alternatives. These failures have important implications for future health-related work on the built environment and other core public health activities.

Adaption to Extreme Rainfall with Open Urban Drainage System: An Integrated Hydrological Cost-Benefit Analysis

NASA Astrophysics Data System (ADS)

Zhou, Qianqian; Panduro, Toke Emil; Thorsen, Bo Jellesmark; Arnbjerg-Nielsen, Karsten

2013-03-01

This paper presents a cross-disciplinary framework for assessment of climate change adaptation to increased precipitation extremes considering pluvial flood risk as well as additional environmental services provided by some of the adaptation options. The ability of adaptation alternatives to cope with extreme rainfalls is evaluated using a quantitative flood risk approach based on urban inundation modeling and socio-economic analysis of corresponding costs and benefits. A hedonic valuation model is applied to capture the local economic gains or losses from more water bodies in green areas. The framework was applied to the northern part of the city of Aarhus, Denmark. We investigated four adaptation strategies that encompassed laissez-faire, larger sewer pipes, local infiltration units, and open drainage system in the urban green structure. We found that when taking into account environmental amenity effects, an integration of open drainage basins in urban recreational areas is likely the best adaptation strategy, followed by pipe enlargement and local infiltration strategies. All three were improvements compared to the fourth strategy of no measures taken.

Cultural ecosystem services are a function of people and place, so may change as a location transitions from rural to urban. Singapore has undergone rapid urbanization after its independence in 1965, with a concomitant decline in natural habitat extent and accessibility. Using coastal mangrove forests as a case study habitat, changing cultural values were explored with a novel array of techniques, including qualitative archival analysis (photographs, oral histories), current sources (publically uploaded social media photographs), and surveys of (a) the general public and (b) visitors to publically accessible mangroves. Cultural value changed through time, with a significant transition from intrinsic, intrapersonal values (spiritual, cultural heritage) to instrumental, interpersonal values (recreation, education). Additionally, cultural value varied between different mangroves depending on their public accessibility, and the evolving degree of human interaction with the ecosystem as urban development occured. Cultural values change as development transitions, though mangroves still play an important cultural role in a heavily urbanized environment.

The sound environment and acoustic perception of open-air markets, which are very common in high-density urban open spaces, play important roles in terms of the urban soundscape. Based on objective and subjective measurements of a typical temporary open-air market in Harbin city, China, the effects of the temporary open-air market on the sound environment and acoustic perception were studied, considering different crowd densities. It was observed that a temporary open-air market without zoning increases the sound pressure level and subjective loudness by 2.4dBA and 0.21dBA, respectively, compared to the absence of a temporary market. Different from the sound pressure level and subjective loudness, the relationship between crowd density and the perceived acoustic comfort is parabolic. Regarding the effect of a temporary open-air market with different zones on the sound environment and acoustic perception, when the crowd densities were the same, subjective loudness in the fruit and vegetable sales area was always higher than in the food sales area and the clothing sales area. In terms of acoustic comfort, with an increase in crowd density, acoustic comfort in the fruit and vegetable sales area decreased, and acoustic comfort in the food sales area and the clothing sales area exhibited a parabolic change trend of increase followed by decrease. Overall, acoustic comfort can be effectively improved by better planning temporary open-air markets in high-density urban open spaces. Copyright © 2017 Elsevier B.V. All rights reserved.

To understand the spatial variation in concentrations and compositions of organic micropollutants in marine plastic debris and their sources, we analyzed plastic fragments (∼10 mm) from the open ocean and from remote and urban beaches. Polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), dichloro-diphenyl-trichloroethane and its metabolites (DDTs), polybrominated diphenyl ethers (PBDEs), alkylphenols and bisphenol A were detected in the fragments at concentrations from 1 to 10,000 ng/g. Concentrations showed large piece-to-piece variability. Hydrophobic organic compounds such as PCBs and PAHs were sorbed from seawater to the plastic fragments. PCBs are most probably derived from legacy pollution. PAHs showed a petrogenic signature, suggesting the sorption of PAHs from oil slicks. Nonylphenol, bisphenol A, and PBDEs came mainly from additives and were detected at high concentrations in some fragments both from remote and urban beaches and the open ocean.

Public Health Adaptation to Climate Change in Large Cities: A Global Baseline.

PubMed

Araos, Malcolm; Austin, Stephanie E; Berrang-Ford, Lea; Ford, James D

2016-01-01

Climate change will have significant impacts on human health, and urban populations are expected to be highly sensitive. The health risks from climate change in cities are compounded by rapid urbanization, high population density, and climate-sensitive built environments. Local governments are positioned to protect populations from climate health risks, but it is unclear whether municipalities are producing climate-adaptive policies. In this article, we develop and apply systematic methods to assess the state of public health adaptation in 401 urban areas globally with more than 1 million people, creating the first global baseline for urban public health adaptation. We find that only 10% of the sampled urban areas report any public health adaptation initiatives. The initiatives identified most frequently address risks posed by extreme weather events and involve direct changes in management or behavior rather than capacity building, research, or long-term investments in infrastructure. Based on our characterization of the current urban health adaptation landscape, we identify several gaps: limited evidence of reporting of institutional adaptation at the municipal level in urban areas in the Global South; lack of information-based adaptation initiatives; limited focus on initiatives addressing infectious disease risks; and absence of monitoring, reporting, and evaluation. © The Author(s) 2015.

Monteiro, António; Pais, Luís Andrade; Rodrigues, Carlos; Carvalho, Paulo

2017-10-01

The use of Geographic Information Systems (GIS) has spread to several science areas, from oceanography to geotechnics. Its application in the urban mapping was intensified in the last century, which allowed a great development, due to the use of geographic database, new analysis tools and, more recently, free open source software. Geotechnical cartography struggle with a permanent and large environment re-organization in urban area, due to new building construction, trenching and the drilling of sampling wells and holes. This creates an extra important and largest volume of data at any pre-existence geological map. The main problem results on the fact that the natural environment is covered with buildings and communications system. The purpose of this work is to create a viable geographic information base for geotechnical mapping through a free GIS computer program and open source, with non-traditional cartographic sources, giving preference to open platforms. QGIS was used as software and “Google Maps”, “Bing Maps” and “OpenStreetMap” were applied as cartographic sources using the “OpenLayers plugin” module. Finally, we also pretend to identify and delimit the degree of granite’s change and fracturing areas using a “Streetview” platform. This model has cartographic input which are a geological map study area, open cartographic web archives and the use of “Streetview” platform. The output has several layouts, such as topography intersection (roads, borders, etc.), with geological map and the bordering area of Guarda Urban Zone. The use of this platform types decrease the collect data time and, sometimes, a careful observation of pictures that were taken during excavations may reveal important details for geological mapping in the study area.

Measuring health and its determinants in urban populations is essential to effectively develop public health policies maximizing health gain within this context. Adolescents are important in this regard given the origins of leading causes of morbidity and mortality develop pre-adulthood. Comprehensive, accurate and comparable information on adolescent urban health indicators from heterogeneous urban contexts is an important challenge. EURO-URHIS 2 aimed to develop standardized tools and methodologies collecting data from adolescents across heterogenous European urban contexts. Questionnaires were developed including (i) comprehensive assessment of urban health indicators from 7 pre-defined domains, (ii) use of previously validated questions from a literature review and other European surveys, (iii) translation/back-translation into European languages and (iv) piloting. Urban area-specific data collection methodologies were established through literature review, consultation and piloting. School-based surveys of 14-16-year olds (400-800 per urban area) were conducted in 13 European countries (33 urban areas). Participation rates were high (80-100%) for students from schools taking part in the surveys from all urban areas, and data quality was generally good (low rates of missing/spoiled data). Overall, 13 850 questionnaires were collected, coded and entered for EURO-URHIS 2. Dissemination included production of urban area health profiles (allowing benchmarking for a number of important public health indicators in young people) and use of visualization tools as part of the EURO-URHIS 2 project. EURO-URHIS 2 has developed standardized survey tools and methodologies for assessing key measures of health and its determinants in adolescents from heterogenous urban contexts and demonstrated the utility of this data to public health practitioners and policy makers. © The Author 2015.

Ekomadyo, A. S.; Nurfadillah, A.; Kartamihardja, A.; Cungwin, A. J.

2018-05-01

The urban architectural heritages of Bandung represents the city’s historical layers. A unique urban architectural element found in Bandung is the heritage neighborhood marketplace. In the style of European post-renaissance urban design, a heritage neighborhood marketplace is initially designed as housing clusters with open spaces as neighborhood centre to create community privacy. But along the time, the neighborhood centre open their enclosed spaces and landmark buildings, transforming itself into small marketplaces with intensively daily activities. Through everyday place-making methods, this article investigates the history and meaning of neighborhood marketplace as everyday urban artefacts through observation, historical study, and interview. The study reveals are three main forces assembling the current form of neighborhood marketplaces in Bandung: Dutch-Indies colonialization, Chinese society trading network, and local traders’ tradition. Dutch-Indies colonialization in Bandung brought European architectural knowledge into neighborhood morphological design that contributed well-defined urban spaces. The Chinese trading network has been at place since the diaspora era and is still continued until now, bridging past and present life through economic activities. Local traders, who came after Dutch-Indies colonialization, fill the empty spaces of neighborhood centres with intensive formal and informal economic activities. Bandung heritage neighborhood marketplaces represent the city’s urban constellation, where global and local political-economic and socio-cultural forces meet in an urban process. Here, the urban heritage is redefined as living artefacts experienced in everyday urban life. Keywords: urban heritage, place making, neighborhood marketplace, Bandung, urban assemblage, living artefacts.

Vehicle emissions are identified as a major source of air pollution in metropolitan areas. Emission control programs in many cities have been implemented as part of larger scale transport policy interventions to control traffic pollutants and reduce public health risks. These interventions include provision of traffic-free and low emission zones and congestion charging. Various studies have investigated the impact of urban street configurations, such as street canyon in urban centers, on pollutants dispersion and roadside air quality. However, there are few investigations in the literature to study the impact of change of fleet composition and street canyon effects on the on-road pollutants concentrations and associated roadside pedestrian exposure to the pollutants. This study presents an experimental investigation on the traffic related gas and particle pollutants in and near major streets in one of the most developed business districts in Hong Kong, known as Central. Both street canyon and open roadway configurations were included in the study design. Mobile measurement techniques were deployed to monitor both on-road and roadside pollutants concentrations at different times of the day and on different days of a week. Multiple traffic counting points were also established to concurrently collect data on traffic volume and fleet composition on individual streets. Street canyon effects were evident with elevated on-road pollutants concentrations. Diesel vehicles were found to be associated with observed pollutant levels. Roadside black carbon concentrations were found to correlate with their on-road levels but with reduced concentrations. However, ultrafine particles showed very high concentrations in roadside environment with almost unity of roadside/on-road ratios possibly due to the accumulation of primary emissions and secondary PM formation. The results from the study provide useful information for the effective urban transport design and bus route reorganization to minimize the impact of traffic emissions on the urban air quality and public health. Observations on the elevated ultrafine particle concentrations in roadside pedestrian levels also demonstrate the urgent need to improve roadside air quality to reduce pedestrians' health risks especially inside street canyon.

Our aim is to conduct an exploratory study to provide an in-depth characterization of a neighborhood's social and physical environment in relation to cardiovascular health. A mixed-methods approach was used to better understand the food, alcohol, tobacco and physical activity domains of the urban environment. We conducted this study in an area of 16,000 residents in Madrid (Spain). We obtained cardiovascular health and risk factors data from all residents aged 45 and above using Electronic Health Records from the Madrid Primary Health Care System. We used several quantitative audit tools to assess: the type and location of food outlets and healthy food availability; tobacco and alcohol points of sale; walkability of all streets and use of parks and public spaces. We also conducted 11 qualitative interviews with key informants to help understanding the relationships between urban environment and cardiovascular behaviors. We integrated quantitative and qualitative data following a mixed-methods merging approach. Electronic Health Records of the entire population of the area showed similar prevalence of risk factors compared to the rest of Madrid/Spain (prevalence of diabetes: 12 %, hypertension: 34 %, dyslipidemia: 32 %, smoking: 10 %, obesity: 20 %). The food environment was very dense, with many small stores (n = 44) and a large food market with 112 stalls. Residents highlighted the importance of these small stores for buying healthy foods. Alcohol and tobacco environments were also very dense (n = 91 and 64, respectively), dominated by bars and restaurants (n = 53) that also acted as food services. Neighbors emphasized the importance of drinking as a socialization mechanism. Public open spaces were mostly used by seniors that remarked the importance of accessibility to these spaces and the availability of destinations to walk to. This experience allowed testing and refining measurement tools, drawn from epidemiology, geography, sociology and anthropology, to better understand the urban environment in relation to cardiovascular health.

Minimizing Surface Exposure to Climate Extremity in Coastal Megacities by Structure Remodelling using Integral Geographic Information System: Lessons from Greater Mumbai Metropolitan

NASA Astrophysics Data System (ADS)

Tiwari, A.

2016-12-01

Coastal metropolitans in South Asia represent the most densely populated and congested urban spaces ranking among the largest urban settlements of the planet. These megacities are characterized by inadequate infrastructure, lack of mitigation tools, and weak resilience of urban ecosystems. Additionally, climate change has increased vulnerability of poor and marginalized population living in rapidly growing coastal megacities to increased frequency, severity and intensity of extreme weather events. This has adversely affected local counter strategies and adaptation tools, transforming such events into hazards with the inability to respond and mitigate. Study aimed to develop a participatory framework for risk reduction in Greater Mumbai Metropolitan by Structure Remodeling (SR) in integral GIS. Research utilized terrain analysis tools and vulnerability mapping, and identified risk susceptible fabric and checked its scope for SR without: 1.adding to its (often) complex fragmentation, and 2.without interference with the ecosystem services accommodated by it. Surfaces available included paved ground, streetscapes commercial facades, rooftops,public spaces, open as well as dark spaces. Remodeling altered certain characteristics in the intrinsic or extrinsic cross-section profile or in both (if suitable) with infrastructure measures (grey, green, blue) that collectively involved ecosystem services and maintained natural hydrological connection. This method fairly reduced exposure of vulnerable surface and minimized risk to achieve extremity-neutral state. Harmonizing with public perception and incorporating priorities of local authorities, the method is significant as it rises above the fundamental challenges arising during management of (often) conflicting perspectives and interests of multiplicity of stakeholders involved at various levels in urban climate governance while ensuring inclusive solutions with reduced vulnerability and increased resilience. Additionally this method has vast potential to replicate for climate smart planning beyond the study region as it clearly ensures barrier free climate-communication process for decision making while looking for long term feasible outcomes of remodeled surface through the most affordable and innovative tools.

Why do people move? Enhancing human mobility prediction using local functions based on public records and SNS data.

PubMed

Kim, Jungmin; Park, Juyong; Lee, Wonjae

2018-01-01

The quality of life for people in urban regions can be improved by predicting urban human mobility and adjusting urban planning accordingly. In this study, we compared several possible variables to verify whether a gravity model (a human mobility prediction model borrowed from Newtonian mechanics) worked as well in inner-city regions as it did in intra-city regions. We reviewed the resident population, the number of employees, and the number of SNS posts as variables for generating mass values for an urban traffic gravity model. We also compared the straight-line distance, travel distance, and the impact of time as possible distance values. We defined the functions of urban regions on the basis of public records and SNS data to reflect the diverse social factors in urban regions. In this process, we conducted a dimension reduction method for the public record data and used a machine learning-based clustering algorithm for the SNS data. In doing so, we found that functional distance could be defined as the Euclidean distance between social function vectors in urban regions. Finally, we examined whether the functional distance was a variable that had a significant impact on urban human mobility.

The Erice 50 Charter titled "Strategies for Diseases Prevention and Health Promotion in Urban Areas" was unanimously approved at the conclusion of the 50th Residential Course "Urban Health. Instruments for promoting health and for assessing hygienic and sanitary conditions in urban areas", held from 29th March to 2nd April 2017 in Erice, at the "Ettore Majorana" Foundation and Centre for Scientific Culture and promoted by the International School of Epidemiology and Preventive Medicine "G. D'Alessandro" and the Study Group "Building Hygiene" of the Italian Society of Hygiene, Preventive Medicine and Public Health (SItI). At the conclusion of the intense learning experience during the Course, with more than 20 lectures, workshops and long-lasting discussions between Professors and Students, the participants identified the major points connecting urban features and Public Health, claiming the pivotal role of urban planning strategies for the management of Diseases Prevention and Health Promotion activities. The Erice 50 Charter is configured as a Decalogue for Healthy Cities and as a Think Tank for designing effective strategic actions and best practices to develop urban regeneration interventions and improve the urban quality of contemporary cities. The Decalogue is structured into the following key strategic objectives: 1. Promoting urban planning interventions that address citizens towards healthy behaviours; 2. Improving living conditions in the urban context; 3. Building an accessible and inclusive city, with a special focus on the frail population; 4. Encouraging the foundation of resilient urban areas; 5. Supporting the development of new economies and employment through urban renewal interventions; 6. Tackling social inequalities; 7. Improving stakeholders' awareness of the factors affecting Public Health in the cities; 8. Ensuring a participated urban governance; 9. Introducing qualitative and quantitative performance tools, capable of measuring the city's attitude to promote healthy lifestyles and to monitor the population's health status; 10. Encouraging sharing of knowledge and accessibility to informations. Finally, all the participants underlined that a multidisciplinary team, composed of Physicians specialized in Hygiene, Preventive Medicine, Public Health and Technicians as Architects, Urban planners and Engineers, is needed to deepen the research topic of Urban Health.

A citizen science campaign encouraging urban forest professionals to engage the public in the collection of tree phenological data

Clarke, K. C.

2009-12-01

There are growing concerns among leading national and local organizations about American scientific literacy, fundamental understanding of science, and the value of scientific research. These organizations, including the University Corporation for Atmospheric Research, have been at the forefront in addressing these concerns. In an effort to improve scientific literacy, research conducted by Sam Droege, among others, suggested using citizen science and public participation as instrumental methods to engage the public. Urban Tree Phenology (UTP), a project of Project BudBurst and the USDA Forest Service, is one such citizen science program that sought to engage the public, including the professionals and amateurs among them, in collecting urban tree phenophase data. UTP participants monitored and reported the stages of phenological events, such as First Leaf and Leaf Fall, of 24 native and cultivated urban tree species, using the steps shown in Figure 1. Data collected will support the long-term research of plant ecology, climate change, public health, urban heat islands on tree physiology, and urban tree management. UTP, using the architectures of online learning, has developed two instructional tutorials to assist data collection (Phase 1). The instructional tutorials were published online, in print and PowerPoint formats, at www.UrbanTreePhenology.com. By completing these tutorials, participants will gain the skills necessary to provide urban tree phenological data to national research databases via the Internet. Phase 2 will test and review the instructional materials developed, and in Phase 3, the administrators of UTP will distribute promotional materials to national research organizations and to participants of the Project BudBurst national citizen science campaign.

A provincial analysis of its urbanisation trends shows shifting and accelerating rural-to-urban migration across the country and accompanying rapid increases in city size and population. The growing disease burden in urban areas attributable to nutrition and lifestyle choices is a major public health challenge, as are troubling disparities in health-care access, vaccination coverage, and accidents and injuries in China's rural-to-urban migrant population. Urban environmental quality, including air and water pollution, contributes to disease both in urban and in rural areas, and traffic-related accidents pose a major public health threat as the country becomes increasingly motorised. To address the health challenges and maximise the benefits that accompany this rapid urbanisation, innovative health policies focused on the needs of migrants and research that could close knowledge gaps on urban population exposures are needed.

Lack of financial resources has become one of the main issues in fulfilling social and physical needs in urban development. The declining levels of public resources make the collaboration between public and private investors necessary. When facing the challenges of ageing population, shared investment may contribute to the appropriate development of sheltered housing to meet the goals of spatial planning as well as certain standards at the level of urban design. By ensuring appropriate living conditions for all generations such urban PPP projects may contribute to the fulfilment of the public interest. The paper presents practice of PPP implementation in Ljubljana, Slovenia, where local authority with the collaboration of private partners ensured more than 400 sheltered apartments in the last years. Examples show the extension of the idea from the 70s onwards in finding new models of housing for the aging population. The development of new models can be a good example of strengthening the cooperation between public and private partners in the field of urban development practice.

Background And Objectives Although Bangladesh has already achieved noticeable progress in the field of development and health, disparities in public health indicators for several markers are still reported. To assess public health development in Bangladesh during the last two decades, firstly, we analysed levels, trends and disparities in public-health-related indicators by rural versus urban as well as by the richest versus poorest group of women who have ever been married. Secondly, using the most recent data set we performed multiple analyses to check whether urban-rural and richest-poorest disparities were still significant. Methods The analysis was based on six nationally representative data sets from the Bangladesh Demographic and Health Surveys (BDHS) conducted in 1993-94 (n=9,640), 1996-1997 (n=9,127), 1999-2000 (n=10,544), 2004 (n=11,440), 2007 (n=10,996) and 2011 (n=17,749). The outcome variables were six selected public-health-related indicators. We performed various types of analyses, including multiple logistic regressions. Results The trend of all indicators except being overweight (1993-2011) displayed gradual improvements for both markers. However, the urban and richest groups revealed a better situation than their counterparts in both simple and multiple analyses. Disparities between richest-poorest groups were more pronounced than urban-rural disparities. For instance, the prevalence of delivery at any healthcare facility in 2011 was 20.4% in rural areas and 46.5% in urban areas, whereas it was 9.1% in the poorest group and 57.6% in the richest group. Conclusion The public health sector in Bangladesh has achieved some successes over the last two decades. However, urban-rural and richest-poorest disparities are still considerable and therefore more public health strategies and efforts are clearly needed for the rural and poorest groups of women in order to reduce these gaps further.

2016-03-19

This study examined the sociodemographic and perceived environmental factors associated with public bicycle use among Taiwanese urban adults. A random-digit-dialing telephone-based cross-sectional survey was administered to Taiwanese urban adults aged 20-64 years in 2015. Data on sociodemographic variables, perceived environmental factors (for attributes identified in the International Physical Activity Questionnaire-Environmental Module), and public bicycle use were obtained from 1002 adults in three cities. Adjusted logistic regression was used. After adjustment for potential confounders, the results showed that adults aged 20-29 years (odds ratio (OR) = 4.42) with a university degree or higher (OR = 2.03) were more likely to use public bicycles. In addition, adults living in Kaohsiung City were less likely to use public bicycles (OR = 0.24). Adults who saw people being active (OR = 1.76; 95% CI: 1.05-2.86) and had positive aesthetic experiences of their environment (OR = 1.69) were more likely to use public bicycles. Our findings suggest that seeing physically active people and positive aesthetic perceptions of the environment are key factors for developing transportation policies and intervention strategies for promoting public bicycle use among Taiwanese urban adults.

2018-02-01

Reduced access to care and barriers have been shown in rural populations and in publicly insured populations. Barriers limiting health care access in publicly insured populations living in rural areas are not understood. This study investigates rural-urban differences in system-, provider-, and individual-level barriers and access to preventive care among adults and children enrolled in a public insurance program in Minnesota. This was a secondary analysis of a 2008 statewide, cross-sectional survey of publicly insured adults and children (n = 4,388) investigating barriers associated with low utilization of preventive care. Sampling was stratified with oversampling of racial/ethnic minorities. Rural enrollees were more likely to report no past year preventive care compared to urban enrollees. However, this difference was no longer statistically significant after controlling for demographic and socioeconomic factors (OR: 1.37, 95% CI: 1.00-1.88). Provider- and system-level barriers associated with low use of preventive care among rural enrollees included discrimination based on public insurance status (OR: 2.26, 95% CI: 1.34-2.38), cost of care concerns (OR: 1.72, 95% CI: 1.03-2.89) and uncertainty about care being covered by insurance (OR: 1.70, 95% CI: 1.01-2.85). These and additional provider-level barriers were also identified among urban enrollees. Discrimination, cost of care, and uncertainty about insurance coverage inhibit access in both the rural and urban samples. These barriers are worthy targets of interventions for publicly insured populations regardless of residence. Future studies should investigate additional factors associated with access disparities based on rural-urban residence. © 2017 National Rural Health Association.

Assessing point-of-use ultraviolet disinfection for safe water in urban developing communities.

2014-12-01

Residents of urban developing communities often have a tap in their home providing treated and sometimes filtered water but its microbial quality cannot be guaranteed. Point-of-use (POU) disinfection systems can provide safe drinking water to the millions who lack access to clean water in urban communities. While many POU systems exist, there are several concerns that can lead to low user acceptability, including low flow rate, taste and odor issues, high cost, recontamination, and ineffectiveness at treating common pathogens. An ultraviolet (UV) POU system was constructed utilizing developing community-appropriate materials and simple construction techniques based around an inexpensive low-wattage, low pressure UV bulb. The system was tested at the bench scale to characterize its hydrodynamic properties and microbial disinfection efficacy. Hydraulically the system most closely resembled a plug flow reactor with minor short-circuiting. The system was challenge tested and validated for a UV fluence of 50 mJ/cm(2) and greater, over varying flow rates and UV transmittances, corresponding to a greater than 4 log reduction of most pathogenic bacteria, viruses, and protozoa of public health concern. This study presents the designed system and testing results to demonstrate the potential architecture of a low-cost, open-source UV system for further prototyping and field-testing.

2014-01-01

Tick-borne diseases represent major public and animal health issues worldwide. Ixodes ricinus, primarily associated with deciduous and mixed forests, is the principal vector of causative agents of viral, bacterial, and protozoan zoonotic diseases in Europe. Recently, abundant tick populations have been observed in European urban green areas, which are of public health relevance due to the exposure of humans and domesticated animals to potentially infected ticks. In urban habitats, small and medium-sized mammals, birds, companion animals (dogs and cats), and larger mammals (roe deer and wild boar) play a role in maintenance of tick populations and as reservoirs of tick-borne pathogens. Presence of ticks infected with tick-borne encephalitis virus and high prevalence of ticks infected with Borrelia burgdorferi s.l., causing Lyme borreliosis, have been reported from urbanized areas in Europe. Emerging pathogens, including bacteria of the order Rickettsiales (Anaplasma phagocytophilum, “Candidatus Neoehrlichia mikurensis,” Rickettsia helvetica, and R. monacensis), Borrelia miyamotoi, and protozoans (Babesia divergens, B. venatorum, and B. microti) have also been detected in urban tick populations. Understanding the ecology of ticks and their associations with hosts in a European urbanized environment is crucial to quantify parameters necessary for risk pre-assessment and identification of public health strategies for control and prevention of tick-borne diseases.

2017-11-01

Energy-efficient urbanization and public health pose major development challenges for India. While both issues are intensively studied, their interaction is not well understood. Here we explore the relationship between urban infrastructures, public health, and household-related emissions, identifying potential synergies and trade-offs of specific interventions by analyzing nationally representative household surveys from 2005 and 2012. Our analysis confirms previous characterizations of the environmental-health transition, but also points to an important role of energy use and urbanization as modifiers of this transition. We find that non-motorized transport may prove a sweet spot for development, as its use is associated with lower emissions and better public health in cities. Urbanization and improved access to basic services correlate with lower short-term morbidity (STM), such as fever, cough and diarrhea. Our analysis suggests that a 10% increase in urbanization from current levels and concurrent improvement in access to modern cooking and clean water could lower STM for 2.4 million people. This would be associated with a modest increase in electricity related emissions of 84 ktCO2e annually. Promoting energy-efficient mobility systems, for instance by a 10% increase in bicycling, could lower chronic conditions like diabetes and cardio-vascular diseases for 0.3 million people while also abating emissions. These findings provide empirical evidence to validate that energy-efficient and sustainable urbanization can address both public health and climate change challenges simultaneously.

2010-04-01

The University at Albany Prevention Research Center, guided by a needs assessment in two underserved communities (one urban, one rural), initiated a pilot project that opened a public school for community walking in a rural setting. This study examined a 9-week program for potential barriers, benefits, influential factors, and the physical activity levels of program participants. Evaluation was based on daily logs, pedometer diaries, participant surveys, and focus groups. Results indicated that rural schools provide a useful resource for residents and increase participants' physical activity levels. A more comprehensive rural community walking program has been implemented as a result of these findings.

Reach-scale effects of riparian forest cover on urban stream ecosystems

2005-01-01

We compared habitat and biota between paired open and forested reaches within five small streams (basin area 10?20 km2) in suburban catchments (9%?49% urban land cover) in the Piedmont of Georgia, USA. Stream reaches with open canopies were narrower than forested reaches (4.1 versus 5.0 m, respectively). There were no differences in habitat diversity (variation in velocity, depth, or bed particle size) between open and forested reaches. However, absence of local forest cover corresponded to decreased large wood and increased algal chlorophyll a standing crop biomass. These differences in basal food resources translated into higher densities of fishes in open (9.0 individuals?m?2) versus forested (4.9 individuals?m?2) reaches, primarily attributed to higher densities of the herbivore Campostoma oligolepis. Densities of terrestrial invertebrate inputs were higher in open reaches; however, trends suggested higher biomass of terrestrial inputs in forested reaches and a corresponding higher density of terrestrial prey consumed by water column feeding fishes. Reach-scale biotic integrity (macroinvertebrates, salamanders, and fishes) was largely unaffected by differences in canopy cover. In urbanizing areas where catchment land cover drives habitat and biotic quality, management practices that rely exclusively on forested riparian areas for stream protection are unlikely to be effective at maintaining ecosystem integrity.

Who serves the urban poor? A geospatial and descriptive analysis of health services in slum settlements in Dhaka, Bangladesh

2015-01-01

In Bangladesh, the health risks of unplanned urbanization are disproportionately shouldered by the urban poor. At the same time, affordable formal primary care services are scarce, and what exists is almost exclusively provided by non-government organizations (NGOs) working on a project basis. So where do the poor go for health care? A health facility mapping of six urban slum settlements in Dhaka was undertaken to explore the configuration of healthcare services proximate to where the poor reside. Three methods were employed: (1) Social mapping and listing of all Health Service Delivery Points (HSDPs); (2) Creation of a geospatial map including Global Positioning System (GPS) co-ordinates of all HSPDs in the six study areas and (3) Implementation of a facility survey of all HSDPs within six study areas. Descriptive statistics are used to examine the number, type and concentration of service provider types, as well as indicators of their accessibility in terms of location and hours of service. A total of 1041 HSDPs were mapped, of which 80% are privately operated and the rest by NGOs and the public sector. Phamacies and non-formal or traditional doctors make up 75% of the private sector while consultation chambers account for 20%. Most NGO and Urban Primary Health Care Project (UPHCP) static clinics are open 5–6 days/week, but close by 4–5 pm in the afternoon. Evening services are almost exclusively offered by private HSDPs; however, only 37% of private sector health staff possess some kind of formal medical qualification. This spatial analysis of health service supply in poor urban settlements emphasizes the importance of taking the informal private sector into account in efforts to increase effective coverage of quality services. Features of informal private sector service provision that have facilitated market penetration may be relevant in designing formal services that better meet the needs of the urban poor.

Throughout the developing world, urban centers with sprawling slum settlements are rapidly expanding and invading previously forested ecosystems. Slum communities are characterized by untended refuse, open sewers, and overgrown vegetation, which promote rodent infestation. Norway rats (Rattus norvegicus), are reservoirs for epidemic transmission of many zoonotic pathogens of public health importance. Understanding the population ecology of R. norvegicus is essential to formulate effective rodent control strategies, as this knowledge aids estimation of the temporal stability and spatial connectivity of populations. We screened for genetic variation, characterized the population genetic structure, and evaluated the extent and patterns of gene flow in the urban landscape using 17 microsatellite loci in 146 rats from 9 sites in the city of Salvador, Brazil. These sites were divided between three neighborhoods within the city spaced an average of 2.7 km apart. Surprisingly, we detected very little relatedness among animals trapped at the same site and found high levels of genetic diversity, as well as structuring across small geographic distances. Most FST comparisons among sites were statistically significant, including sites <400 m apart. Bayesian analyses grouped the samples in three genetic clusters, each associated with distinct sampling sites from different neighborhoods or valleys within neighborhoods. These data indicate the existence of complex genetic structure in R. norvegicus in Salvador, linked to the heterogeneous urban landscape. Future rodent control measures need to take into account the spatial and temporal linkage of rat populations in Salvador, as revealed by genetic data, to develop informed eradication strategies.

This study assessed the disparity in nutritional status of adolescents between public and private schools in urban Gambia. This is a school-based cross-sectional study in six private and six public upper basic schools in urban Gambia. This study recruited 491 students from public and 469 students from private schools (13-15 years of age). The prevalence of stunting (WHO height-for-age Z < -2SD) was 13.4 % for public school students and 4.5 % for private schools. After adjustment for children's sex, age, and family socioeconomic status, the differences in prevalence of stunting and underweight were significant between public and private schools. Private school students are more likely to be overweight/obese (WHO BMI-for-age Z > +1SD) (OR = 2.85, 95 % CI 1.55-5.22), but less likely to be thin (BMI-for-age Z < -2SD) (OR = 0.61 [0.39-0.96]), compared to public school students. Children from lower income families had lower odds for overweight/obese than normal weight, compared to those from higher income families (OR = 0.34 [0.15-0.76]). Public and private schools in urban regions of the Gambia may face different nutritional challenges due to differences in school environment and resources.

Public counselling: Brazilian Pentecostal intimate performances among urban women in Mozambique.

PubMed

van de Kamp, Linda

2013-01-01

Analysing the public character of Brazilian Pentecostal counselling sessions in urban Mozambique, this paper aims to examine the configurations of exposure through which counselling acquires and produces sociocultural forms of intimacy. During 'therapy of love' sessions held by the Brazilian Universal Church of the Kingdom of God, strict bodily acts need to be performed publicly to authorise love. Drawing on the notion of religious habitus, the paper focuses on how the performativity of Brazilian Pentecostal counselling practices responds to and shapes a public culture of love and intimacy among upwardly mobile women in urban Mozambique, and how the performative scripts converts carry out during therapy result in ambiguous relationships.

The world is urbanizing rapidly. According to the United Nation's World Urbanization Prospect, 50% of the global population already lives in urban areas today. This number is expected to grow to 66% by 2050. The rapid changes in these urban environments go hand in hand with rapid changes in natural hazard risks, in particular in informal unplanned neighbourhoods. In Dar Es Salaam - Tanzania, flood risk dominates and given the rapid changes in the city, continuous updates of detailed street level hazard and risk mapping are needed to adequately support decision making for urban planning, infrastructure design and disaster response. Over the past years, the Ramani Huria and Zuia Mafuriko projects have mapped the most flood prone neighbourhoods, including roads, buildings, drainage and land use and contributed data to the open-source OpenStreetMap database. In this contribution, we will demonstrate how we mobilize these contributed data to establish dynamic flood models for Dar Es Salaam and keep these up-to-date by making a direct link between the data, and model schematization. The tools automatically establish a sound 1D drainage network as well as a high resolution terrain dataset, by fusing the OpenStreetMap data with existing lower resolution terrain data such as the globally available satellite based SRTM 30. It then translates these fully automatically into the inputs required for the D-HYDRO modeling suite. Our tools are built such that community and stakeholder knowledge can be included in the model details through workshops with the tools so that missing essential information about the city's details can be augmented on-the-fly. This process creates a continuous dialogue between members of the community that collect data, and stakeholders requiring data for flood models. Moreover, used taxonomy and data filtering can be configured to conditions in other cities, making the tools generic and scalable. The tools are made available open-source.

By adopting gradient analysis combining with the analysis of urban land use degree, this paper studied the spatial layout characteristics of residential and industrial lands in new Yinzhou Town, and explored the location characters of various urban land use by selecting public green land, public facilities, and road as the location advantage factors. Gradient analysis could effectively connect with the spatial layout of urban land use, and quantitatively depict the spatial character of urban land use. In the new town, there was a new urban spatial center mostly within the radius of 2 km, namely, the urban core area had obvious location advantage in the cross-shaft direction urban development. On the south of Yinzhou Avenue, the urban hinterland would be constructed soon. In the future land use of the new town, the focus would be the reasonable vicissitude of industrial land after the adjustment of industrial structure, the high-efficient intensive use of the commercial land restricted by the compulsive condition of urban core area, and the agricultural land protection in the southeastern urban-rural fringe.

Why do people move? Enhancing human mobility prediction using local functions based on public records and SNS data

PubMed Central

Park, Juyong

2018-01-01

The quality of life for people in urban regions can be improved by predicting urban human mobility and adjusting urban planning accordingly. In this study, we compared several possible variables to verify whether a gravity model (a human mobility prediction model borrowed from Newtonian mechanics) worked as well in inner-city regions as it did in intra-city regions. We reviewed the resident population, the number of employees, and the number of SNS posts as variables for generating mass values for an urban traffic gravity model. We also compared the straight-line distance, travel distance, and the impact of time as possible distance values. We defined the functions of urban regions on the basis of public records and SNS data to reflect the diverse social factors in urban regions. In this process, we conducted a dimension reduction method for the public record data and used a machine learning-based clustering algorithm for the SNS data. In doing so, we found that functional distance could be defined as the Euclidean distance between social function vectors in urban regions. Finally, we examined whether the functional distance was a variable that had a significant impact on urban human mobility. PMID:29432440

Built Environment and Active Commuting: Rural-Urban Differences in the U.S.

PubMed

Fan, Jessie X; Wen, Ming; Wan, Neng

2017-12-01

The purpose of this research was to investigate rural-urban differences in participation rates in three modes of active commuting (AC) and their built environmental correlates. The 2010 Census supplemented with other datasets were used to analyze AC rates in percent of workers age 16+ walking, biking, or taking public transportation to work in 70,172 Census tracts, including 12,844 rural and 57,328 urban. Random-intercept factional logit regressions were used to account for zero-inflated data and for clustering of tracts within counties. We found that the average AC rates were 3.44% rural and 2.77% urban (p<0.01) for walking to work, 0.40% rural and 0.58% urban (p<0.01) for biking to work, and 0.59% rural and 5.86% urban (p<0.01) for public transportation to work. Some environmental variables had similar relationships with AC in rural and urban tracts, such as a negative association between tract greenness and prevalence of walking to work. Others had opposite correlational directions for rural vs. urban, such as street connectivity for walking to work and population density for both walking to work and public transportation to work. We concluded that rurality is an important moderator in AC-environment relationships. In developing strategies to promote AC, attention needs to be paid to rural-urban differences to avoid unintended consequences.

Better parks through law and policy: a legal analysis of authorities governing public parks and open spaces.

PubMed

Henderson, Ana; Fry, Christine R

2011-01-01

Improving parks in low income and minority neighborhoods may be a key way to increase physical activity and decrease overweight and obesity prevalence among children at the greatest risk. To advocate effectively for improved recreation infrastructure, public health advocates must understand the legal and policy landscape in which public recreation decisions are made. In this descriptive legal analysis, we reviewed federal, state, and local laws to determine the authority of each level of government over parks. We then examined current practices and state laws regarding park administration in urban California and rural Texas. We identified several themes through the analysis: (1) multiple levels of governments are often involved in parks offerings in a municipality, (2) state laws governing parks vary, (3) local authority may vary substantially within a state, and (4) state law may offer greater authority than local jurisdictions use. Public health advocates who want to improve parks need to (1) think strategically about which levels of government to engage; (2) identify parks law and funding from all levels of government, including those not typically associated with local parks; and (3) partner with advocates with similar interests, including those from active living and school communities.

Sercaianu, Mihai; Petrescu, Florian; Aldea, Mihaela; Oana, Luca; Rotaru, George

2015-06-01

In the last decade, reducing urban pollution and improving quality of public spaces became a more and more important issue for public administration authorities in Romania. The paper describes the development of a web-GIS solution dedicated to monitoring of the green infrastructure in Bucharest, Romania. Thus, the system allows the urban residents (citizens) to collect themselves and directly report relevant information regarding the current status of the green infrastructure of the city. Consequently, the citizens become an active component of the decision-support process within the public administration. Besides the usual technical characteristics of such geo-information processing systems, due to the complex legal and organizational problems that arise in collecting information directly from the citizens, additional analysis was required concerning, for example, local government involvement, environmental protection agencies regulations or public entities requirements. Designing and implementing the whole information exchange process, based on the active interaction between the citizens and public administration bodies, required the use of the "citizen-sensor" concept deployed with GIS tools. The information collected and reported from the field is related to a lot of factors, which are not always limited to the city level, providing the possibility to consider the green infrastructure as a whole. The "citizen-request" web-GIS for green infrastructure monitoring solution is characterized by a very diverse urban information, due to the fact that the green infrastructure itself is conditioned by a lot of urban elements, such as urban infrastructures, urban infrastructure works and construction density.

This study assessed the public's health risk awareness of urban air pollution triggered by three megacities in China, and the data are the responses from a sample size of 3868 megacity inhabitants from Shanghai, Nanchang and Wuhan. Descriptive analyses were used to summarize the respondents' demographics, perceived health risks from air pollution and sources of health-related knowledge on urban air pollution. Chi-square tests were used to examine if participants' demographics were associated with participant's general attitudes towards current air quality and the three perceived highest health risks due to urban air pollution. We found low rate of satisfaction of current urban air quality as well as poor knowledge of air pollution related indicator. Participants' gender, age and travel experience were found to be associated with the satisfaction of current air quality. The knowledge of air pollution related indicator was significantly affected by respondents' education, monthly income, health status, and sites of study. As many as 46.23% of the participants expressed their feelings of anxiety when exposed to polluted air, especially females, older adults and those with poor health conditions. Most participants believed that coughs/colds, eye problems and skin allergies were the three highest health risks due to urban air pollution based on public education through television/radio, internet and newspaper/magazine. Further public health education is needed to improve public awareness of air pollution and its effects.

Abundance of diurnal raptors on open space grasslands in an urbanized landscape

Berry, M.E.; Bock, C.E.; Haire, S.L.

1998-01-01

We conducted point counts of diurnal raptors on Boulder, Colorado, grasslands for three winters and summers, and compared results to landscape features of the count areas. Four wintering species were scarce on plots that included significant amounts of urban habitat, with a critical landscape threshold at about 5-7% urbanization: Bald Eagle (Haliaeetus leucocephalus), Ferruginous Hawk (Buteo regalis), Rough-legged Hawk (B. lagopus), and Prairie Falcon (Falco mexicanus). Counts of the first three species also were positively correlated with proximity of the count plots to the nearest colony of black-tailed prairie dogs (Cynomys ludovicianus). Two breeding species, the Red-tailed Hawk (B. jamaicensis) and Swainson's Hawk (B. swainsoni), were more abundant on plots dominated by lowland hayfields and tallgrass prairies, as opposed to upland mixed and shortgrass prairies. They, along with the ubiquitous American Kestrel (Falco sparverius), were not sensitive to the amounts of urbanization (up to 30%) that occurred in the landscapes sampled. Results of this study suggest that urban open space grasslands can support sizable populations of most diurnal raptors, as long as prey populations persist, but that some species are highly sensitive to landscape urbanization.

The relationship between urban forests and income: A meta-analysis.

PubMed

Gerrish, Ed; Watkins, Shannon Lea

2018-02-01

Urban trees provide substantial public health and public environmental benefits. However, scholarly works suggest that urban trees may be unequally distributed among poor and minority urban communities, meaning that these communities are potentially being deprived of public environmental benefits, a form of environmental injustice. The evidence of this problem is not uniform however, and evidence of inequity varies in size and significance across studies. This variation in results suggests the need for a research synthesis and meta-analysis. We employed a systematic literature search to identify original studies which examined the relationship between urban forest cover and income (n=61) and coded each effect size (n=332). We used meta-analytic techniques to estimate the average (unconditional) relationship between urban forest cover and income and to estimate the impact that methodological choices, measurement, publication characteristics, and study site characteristics had on the magnitude of that relationship. We leveraged variation in study methodology to evaluate the extent to which results were sensitive to methodological choices often debated in the geographic and environmental justice literature but not yet evaluated in environmental amenities research. We found evidence of income-based inequity in urban forest cover (unconditional mean effect size = 0.098; s.e. = .017) that was robust across most measurement and methodological strategies in original studies and results did not differ systematically with study site characteristics. Studies that controlled for spatial autocorrelation, a violation of independent errors, found evidence of substantially less urban forest inequity; future research in this area should test and correct for spatial autocorrelation.

Moving the Barricades to Physical Activity: A Qualitative Analysis of Open Streets Initiatives Across the United States.

Eyler, Amy A; Hipp, J Aaron; Lokuta, Julie

2015-01-01

Ciclovía, or Open Streets initiatives, are events where streets are opened for physical activity and closed to motorized traffic. Although the initiatives are gaining popularity in the United States, little is known about planning and implementing them. The goals of this paper are to explore the development and implementation of Open Streets initiatives and make recommendations for increasing the capacity of organizers to enhance initiative success. Phenomenology with qualitative analysis of structured interviews was used. Study setting was urban and suburban communities in the United States. Study participants were organizers of Open Streets initiatives in U.S. cities. Using a list of 47 events held in 2011, 27 lead organizers were interviewed by telephone about planning, implementation, and lessons learned. The interviews were digitally recorded and transcribed. A phenomenologic approach was used, an initial coding tool was developed after reviewing a sample of transcripts, and constant comparative coding methodology was applied. Themes and subthemes were generated from codes. The most common reasons for initiation were to highlight or improve health and transportation. Most initiatives aimed to reach the general population, but some targeted families, children, or specific neighborhoods. Getting people to understand the concept of Open Streets was an important challenge. Other challenges included lack of funding and personnel, and complex logistics. These initiatives democratize public space for citizens while promoting physical activity, social connectedness, and other broad agendas. There are opportunities for the research community to contribute to the expanse and sustainability of Open Streets, particularly in evaluation and dissemination.

User-based representation of time-resolved multimodal public transportation networks.

Alessandretti, Laura; Karsai, Márton; Gauvin, Laetitia

2016-07-01

Multimodal transportation systems, with several coexisting services like bus, tram and metro, can be represented as time-resolved multilayer networks where the different transportation modes connecting the same set of nodes are associated with distinct network layers. Their quantitative description became possible recently due to openly accessible datasets describing the geo-localized transportation dynamics of large urban areas. Advancements call for novel analytics, which combines earlier established methods and exploits the inherent complexity of the data. Here, we provide a novel user-based representation of public transportation systems, which combines representations, accounting for the presence of multiple lines and reducing the effect of spatial embeddedness, while considering the total travel time, its variability across the schedule, and taking into account the number of transfers necessary. After the adjustment of earlier techniques to the novel representation framework, we analyse the public transportation systems of several French municipal areas and identify hidden patterns of privileged connections. Furthermore, we study their efficiency as compared to the commuting flow. The proposed representation could help to enhance resilience of local transportation systems to provide better design policies for future developments.

Witten, Karen; Hiscock, Rosemary; Pearce, Jamie; Blakely, Tony

2008-09-01

Increasing population levels of physical activity is high on the health agenda in many countries. There is some evidence that neighbourhood access to public open space can increase physical activity by providing easier and more direct access to opportunities for exercise. This national study examines the relationship between travel time access to parks and beaches, BMI and physical activity in New Zealand neighbourhoods. Access to parks and beaches, measured in minutes taken by a car, was calculated for 38,350 neighbourhoods nationally using Geographic Information Systems. Multilevel regression analyses were used to establish the significance of access to these recreational amenities as a predictor of BMI, and levels of physical activity and sedentary behaviour in the 12,529 participants, living in 1178 neighbourhoods, of the New Zealand Health Survey 2002/3. Neighbourhood access to parks was not associated with BMI, sedentary behaviour or physical activity, after controlling for individual-level socio-economic variables, and neighbourhood-level deprivation and urban/rural status. There was some evidence of a relationship between beach access and BMI and physical activity in the expected direction. This study found little evidence of an association between locational access to open spaces and physical activity.

Communicating Climate Hazards Information in the Urban Community to the Public

NASA Astrophysics Data System (ADS)

McCalla, M. R.

2004-12-01

Climate simulations are predicting an overall warming of the atmosphere due to greenhouse gases. For example, CO2 allows sunlight to reach the earth and warm its surface, but it prevents a portion of this surface heat from escaping the atmosphere. This greenhouse effect can result in higher mean atmospheric temperatures near the Earth's surface. If these predictions are correct, changes in temperature can increase the power demand to cool urban building structures (homes, schools, offices, storage facilities, etc.). Similarly, the regional and seasonal temperature fluctuations due to climate oscillations (El Nino, for example) may also increase the power demand for heating and cooling. A warming climate (or cooling climate, for that matter) can also affect the available water for drinking, irrigation, and generating power, all of which impact the viability and sustainability of the urban community. Additionally, urban areas are expanding. Consequently, the distance between city and wildlands is decreasing. The wildland-urban interface often stresses biodiversity, forestation, and the urban area's ability to respond adequately to such climate-induced hazards as forest fires, flooding, and coastal erosion. Thus climate has an impact on humans and vice versa. How can scientists communicate the impact of climate on the urban community? What is the best way to communicate the information so that the public can (1) be informed and (2) make informed decisions? How well is the nexus between climate science and impacts on and benefits to decision makers understood? What is the best way to fully exploit that connection so that the public can develop intervention measures to support the urban community's response to climatic impacts? The Office of the Federal Coordinator for Meteorological Services and Supporting Research (OFCM) is an interdepartmental office established in response to Public Law 87-843 with the express purpose of ensuring the effective use of federal meteorological resources by leading the systematic coordination of operational weather and climate requirements, services, products, capabilities, information, modeling, and supporting research among the federal agencies. Toward that end, the OFCM, in partnership with the Department of Homeland Security Science and Technology Directorate, is sponsoring a September 2004 forum on urban meteorology. The theme of the forum is "Information to Improve Community Responses to Urban Atmospheric Hazards, Weather Events, and Climate." Forum participants and speakers will come from both the public and private sectors, as well as the academic community. The output of the forum will be to specifically answer such questions as (1) how will emerging technologies help communicate risks more effectively to the urban community; (2) how can education, outreach, and training be more effective in eliciting an appropriate public response; and (3) what methods are needed to better communicate and disseminate climate information to the public? The communication recommendations stemming from the urban meteorology forum will be shared with AGU conference participants.

Socio-cultural acceptability of urine diverted composting toilets: A review of literature for possible adoption in peri-urban areas as a sustainable sanitation solution

NASA Astrophysics Data System (ADS)

Ahmed, Sk. Kabir; Ahmed, Sarder Shakil

2017-12-01

The improvements of strategies and treatment options adapted to conditions prevailing in developing countries have long been neglected as regards faecal sludge (FS) - the by-products of on-site sanitation installations. In recent years, an encouraging number of initiatives towards improved FS management, including appropriate FS treatment schemes, have been developed, particularly in Nepal, Thailand, Vietnam and Bangladesh. These initiatives assist urban and peri-urban dwellers and authorities to overcome the challenges of undifferentiating and uncontrolled disposal of faecal sludge into drains, canals and onto open spaces, thus producing a "faecal film" in urban areas that impair public health and cause pollution. Though people around the world are buying, or being offered with, pit latrines, shared toilets, or other enhanced sanitation solutions, this is vital to reduce transmission of diseases; questions arise about how to deal with the fecal sludge management. Sanitation is the hygienic way of upholding health through avoidance of human contact with the hazards of wastes as well as the treatment and proper disposal of sewage or wastewater. Waterborne diseases are the single most vital cause of death and illness in developing countries. The understanding of social issues is paramount introducing an alternative sanitation system. Although treating excreta is a universal aspect of human existence, the topic has not been rigorously investigated by social scientists identifying three cultural influences that affect the acceptance (or rejection) of an alternative sanitation system: psychology, religion and gender. Composting literature review focuses on increasing awareness and developing good understanding of composting toilets as an alternative urban sanitation technology.

The role of landscape and habitat characteristics in limiting abundance of grassland nesting songbirds in an urban open space

USGS Publications Warehouse

Haire, S.; Bock, C.E.; Cade, B.S.; Bennett, B.C.

2000-01-01

We examine the relationships between abundance of grassland nesting songbirds observed in the Boulder Open Space, CO, USA and parameters that described landscape and habitat characteristics, in order to provide information for Boulder Open Space planners and managers. Data sets included bird abundance and plant species composition, collected during three breeding seasons (1994–1996), and landscape composition and configuration measures from a satellite image-derived land-cover map. We used regression quantiles to estimate the limitations imposed on bird abundance by urban encroachment and decreasing areas of grassland cover-types on the landscape, and habitat characteristics within 200 m diameter sample plots. After accounting for the effect of landscape grassland composition on four species (Western Meadowlark (Sturnella neglecta), Vesper Sparrow (Pooecetes gramineus), Horned Lark (Eremophila alpestris), and Grasshopper Sparrow (Ammodramus savannarum)), change in abundance with proportion of urban area in the landscape was consistent with the pattern expected for limiting factors that were the active constraint at some times and places. Area of preferred grassland cover-types on the landscape was important for all species, and this remained the case when habitat variables were included in combined landscape–habitat models, with one exception (Western Meadowlark). Analysis of habitat variables enabled identification of important features at the local scale (e.g. shale plant communities in Lark Sparrow (Chondestes grammacus) habitat) that were indistinguishable using landscape data alone. Consideration of changes in the landscape due to urbanization and loss of grassland habitat are crucial for open space planning, and habitat features associated with localized and clumped bird species distributions provide important additional information. Widening the management focus to include areas that are not part of the open space system will facilitate a more complete understanding of potential limiting factor processes.

[Who Hits the Mark? A Comparative Study of the Free Geocoding Services of Google and OpenStreetMap].

Lemke, D; Mattauch, V; Heidinger, O; Hense, H W

2015-09-01

Geocoding, the process of converting textual information (addresses) into geographic coordinates is increasingly used in public health/epidemiological research and practice. To date, little attention has been paid to geocoding quality and its impact on different types of spatially-related health studies. The primary aim of this study was to compare 2 freely available geocoding services (Google and OpenStreetMap) with regard to matching rate (percentage of address records capable of being geocoded) and positional accuracy (distance between geocodes and the ground truth locations). Residential addresses were geocoded by the NRW state office for information and technology and were considered as reference data (gold standard). The gold standard included the coordinates, the quality of the addresses (4 categories), and a binary urbanity indicator based on the CORINE land cover data. 2 500 addresses were randomly sampled after stratification for address quality and urbanity indicator (approximately 20 000 addresses). These address samples were geocoded using the geocoding services from Google and OSM. In general, both geocoding services showed a decrease in the matching rate with decreasing address quality and urbanity. Google showed consistently a higher completeness than OSM (>93 vs. >82%). Also, the cartographic confounding between urban and rural regions was less distinct with Google's geocoding API. Regarding the positional accuracy of the geo-coordinates, Google also showed the smallest deviations from the reference coordinates, with a median of <9 vs. <175.8 m. The cumulative density function derived from the positional accuracy showed for Google that nearly 95% and for OSM 50% of the addresses were geocoded within <50 m of their reference coordinates. The geocoding API from Google is superior to OSM regarding completeness and positional accuracy of the geocoded addresses. On the other hand, Google has several restrictions, such as the limitation of the requests to 2 500 addresses per 24 h and the presentation of the results exclusively on Google Maps, which may complicate the use for scientific purposes. © Georg Thieme Verlag KG Stuttgart · New York.

City, region, and in between: New York City's water supply and the insights of regional history.

PubMed

Soll, David

2012-01-01

Urban historians have greatly expanded their geographical purview in recent years, incorporating suburbs and hinterlands into their analysis of social and environmental change. Urban environmental historians and suburban historians have played a critical role in the regionalization of urban history over the last decade. This case study of the development of New York City’s water supply reveals the benefits of taking a regional approach to urban history. From the New York Public Library to Central Park’s Great Lawn to neighborhood parks, the New York City landscape bears the traces of the continuous development of the city’s water network. Expansion of the water system in rural hinterlands enabled municipal officials to put urban reservoirs to new uses, creating some of the city’s most beloved public spaces. The rehabilitation of urban infrastructure underscores the intimate linkages between rural development and the urban built environment.

Using Video to Communicate Scientific Findings -- Habitat Connections in Urban Streams

NASA Astrophysics Data System (ADS)

Harned, D. A.; Moorman, M.; Fitzpatrick, F. A.; McMahon, G.

2011-12-01

The U.S Geological Survey (USGS) National Water-Quality Assessment Program (NAWQA) provides information about (1) water-quality conditions and how those conditions vary locally, regionally, and nationally, (2) water-quality trends, and (3) factors that affect those conditions. As part of the NAWQA Program, the Effects of Urbanization on Stream Ecosystems (EUSE) study examined the vulnerability and resilience of streams to urbanization. Completion of the EUSE study has resulted in over 20 scientific publications. Video podcasts are being used in addition to these publications to communicate the relevance of these scientific findings to more general audiences such as resource managers, educational groups, public officials, and the general public. An example of one of the podcasts is a film examining effects of urbanization on stream habitat. "Habitat Connections in Urban Streams" explores how urbanization changes some of the physical features that provide in-stream habitat and examines examples of stream restoration projects designed to improve stream form and function. The "connections" theme is emphasized, including the connection of in-stream habitats from the headwaters to the stream mouth; connections between stream habitat and the surrounding floodplains, wetlands and basin; and connections between streams and people-- resource managers, public officials, scientists, and the general public. Examples of innovative stream restoration projects in Baltimore Maryland; Milwaukee, Wisconsin; and Portland Oregon are shown with interviews of managers, engineers, scientists, and others describing the projects. The film is combined with a website with links to extended film versions of the stream-restoration project interviews.

The public commonly associates microorganisms with pathogens. This suspicion of microorganisms is understandable, as historically microorganisms have killed more humans than any other agent while remaining largely unknown until the late seventeenth century with the works of van Leeuwenhoek and Kircher. Despite our improved understanding regarding microorganisms, the general public are apt to think of diseases rather than of the majority of harmless or beneficial species that inhabit our bodies and the built and natural environment. As long as microbiome research was confined to labs, the public's exposure to microbiology was limited. The recent launch of global microbiome surveys, such as the Earth Microbiome Project and MetaSUB (Metagenomics and Metadesign of Subways and Urban Biomes) project, has raised ethical, financial, feasibility, and sustainability concerns as to the public's level of understanding and potential reaction to the findings, which, done improperly, risk negative implications for ongoing and future investigations, but done correctly, can facilitate a new vision of "smart cities." To facilitate improved future research, we describe here the major concerns that our discussions with ethics committees, community leaders, and government officials have raised, and we expound on how to address them. We further discuss ethical considerations of microbiome surveys and provide practical recommendations for public engagement.

Ecological concerns following Superstorm Sandy: stressor level and recreational activity levels affect perceptions of ecosystem

PubMed Central

2015-01-01

Coastal habitats are vulnerable to storms, and with increasing urbanization, sea level rise, and storm frequency, some urban populations are at risk. This study examined perceptions of respondents in coastal and central New Jersey to Superstorm Sandy, including: 1) concerns about ecological resources and effects (open-ended question), 2) information sources for ecology of the coast (open-ended), and 3) ratings of a list of ecological services as a function of demographics, location (coastal, central Jersey), stressor level (power outages, high winds, flooding) and recreational rates. “Wildlife” and “fish” were the ecological concerns mentioned most often, while beaches and dunes were most often mentioned for environmental concerns. Television, radio, and web/internet were sources trusted for ecological information. The data indicate 1) stressor level was a better predictor of ratings of ecological services than geographical location, but days engaged in recreation contributed the most to variations in ratings, 2) ecological services were rated the highest by respondents with the highest stressor levels, and by those from the coast, compared to others, 3) Caucasians rated ecological services higher than all others, and 4) recreational rates were highest for coastal respondents, and ratings for ecological services increased with recreational rates. Only 20 % of respondents listed specific ecological services as one of their three most important environmental concerns. These data will be useful for increasing preparedness, enhancing educational strategies for shore protection, and providing managers and public policy makers with data essential to developing resiliency strategies.

The rapid development of information technology has had a great impact on the understanding of urban environment, which brings different spatially psychological experience. Information and image transmission has been full with the streets, both the physical space and virtual space have been unprecedentedly blended together through pictures, images, electronic media and other tools, which also stimulates people’s vision and psychology and gives birth to a more complex form of urban space. Under the dual role of spatial mediumlization and media spatialization, the psychological cognitive pattern of urban public space context is changing.

Container-based sanitation: assessing costs and effectiveness of excreta management in Cap Haitien, Haiti

PubMed Central

Tilmans, Sebastien; Russel, Kory; Sklar, Rachel; Page, Leah; Kramer, Sasha

2015-01-01

Container-based sanitation (CBS) – in which wastes are captured in sealable containers that are then transported to treatment facilities – is an alternative sanitation option in urban areas where on-site sanitation and sewerage are infeasible. This paper presents the results of a pilot household CBS service in Cap Haitien, Haiti. We quantify the excreta generated weekly in a dense urban slum,(1) the proportion safely removed via container-based public and household toilets, and the costs associated with these systems. The CBS service yielded an approximately 3.5-fold decrease in the unmanaged share of faeces produced, and nearly eliminated the reported use of open defecation and “flying toilets” among service recipients. The costs of this pilot small-scale service were higher than those of large-scale waterborne sewerage, but economies of scale have the potential to reduce CBS costs over time. The paper concludes with a discussion of planning and policy implications of incorporating CBS into the menu of sanitation options for rapidly growing cities. PMID:26097288

Environment, wealth, inequality and the burden of disease in the Accra metropolitan area, Ghana.

Boadi, Kwasi Owusu; Kuitunen, Markku

2005-06-01

The study examines environmental problems and adverse impacts on the health of urban households in the Accra metropolitan area, Ghana. Accra is faced with severe inadequacy of urban infrastructure in the face of rapid population growth in the metropolis. More than half of the city's population do not have access to solid waste collection services. Only 39.8% of households have indoor pipe and over 35.0% of households depend on unsanitary public latrines whilst 2.5% do not have access to toilet facilities. Human excrement, garbage and wastewater are usually deposited in surface drains, open spaces and streams in poor neighbourhoods. The resultant poor sanitation has serious health impacts as more than half of reported diseases are related to poor environmental sanitation. The majority of households depend on solid fuels for cooking and this leads to indoor air pollution and high incidence of respiratory infections. Poor households bear a disproportionately large share of the burden of environmental health hazards than their wealthy counterparts, due to their particular vulnerability resulting from inadequate access to environmental health facilities and services.

Buenos Aires - Toward Comprehensive Development and Sustainable Mobility

NASA Astrophysics Data System (ADS)

Kamrowska-Zaluska, Dorota

2017-10-01

This paper is introducing Buenos Aires’ achievements and challenges in implementing comprehensive development and integrating efficient and sustainable transport system within its urban structure. There are several important steps in this process starting from urban regeneration of Puerto Madero, the introduction and then implementation of a strategic plan Modelo territorial (2010) and of Buenos Aires’ Plan de Movilidad Sustentable (2013). The last one - Sustainable Mobility Plan helped Buenos Aires win several prestigious rewards for innovative approach to mobility and sustainable transport and leadership in combating climate change. Buenos Aires City government demonstrates strong leadership by implementing well-planned (Bus Rapid Transport) BRT solutions, stressing the importance of political will and support, flexibility and an open mind in listening to the points of view of all stakeholders involved. Buenos Aires has made a very important step toward sustainability by supporting development of more sustainable modes of transport, such as bicycle-sharing system and improving walkability of the city centre. The last initiative combined with strong focus on public spaces is adding to tourist attractiveness based on diversity of the capital of Argentina.

Urban stormwater harvesting and reuse: a probe into the chemical, toxicology and microbiological contaminants in water quality.

Stormwater is one of the last major untapped urban water resources that can be exploited as an alternative water source in Australia. The information in the current Australian Guidelines for Water Recycling relating to stormwater harvesting and reuse only emphasises on a limited number of stormwater quality parameters. In order to supply stormwater as a source for higher value end-uses, a more comprehensive assessment on the potential public health risks has to be undertaken. Owing to the stochastic variations in rainfall, catchment hydrology and also the types of non-point pollution sources that can provide contaminants relating to different anthropogenic activities and catchment land uses, the characterisation of public health risks in stormwater is complex, tedious and not always possible through the conventional detection and analytical methods. In this study, a holistic approach was undertaken to assess the potential public health risks in urban stormwater samples from a medium-density residential catchment. A combined chemical-toxicological assessment was used to characterise the potential health risks arising from chemical contaminants, while a combination of standard culture methods and quantitative polymerase chain reaction (qPCR) methods was used for detection and quantification of faecal indicator bacteria (FIB) and pathogens in urban stormwater. Results showed that the concentration of chemical contaminants and associated toxicity were relatively low when benchmarked against other alternative water sources such as recycled wastewater. However, the concentrations of heavy metals particularly cadmium and lead have exceeded the Australian guideline values, indicating potential public health risks. Also, high numbers of FIB were detected in urban stormwater samples obtained from wet weather events. In addition, qPCR detection of human-related pathogens suggested there are frequent sewage ingressions into the urban stormwater runoff during wet weather events. Further water quality monitoring study will be conducted at different contrasting urban catchments in order to undertake a more comprehensive public health risk assessment for urban stormwater.

Health Co-Benefits of Green Building Design Strategies and Community Resilience to Urban Flooding: A Systematic Review of the Evidence.

PubMed

Houghton, Adele; Castillo-Salgado, Carlos

2017-12-06

Climate change is increasingly exacerbating existing population health hazards, as well as resulting in new negative health effects. Flooding is one particularly deadly example of its amplifying and expanding effect on public health. This systematic review considered evidence linking green building strategies in the Leadership in Energy and Environmental Design ® (LEED) Rating System with the potential to reduce negative health outcomes following exposure to urban flooding events. Queries evaluated links between LEED credit requirements and risk of exposure to urban flooding, environmental determinants of health, co-benefits to public health outcomes, and co-benefits to built environment outcomes. Public health co-benefits to leveraging green building design to enhance flooding resilience included: improving the interface between humans and wildlife and reducing the risk of waterborne disease, flood-related morbidity and mortality, and psychological harm. We conclude that collaborations among the public health, climate change, civil society, and green building sectors to enhance community resilience to urban flooding could benefit population health.

"New Sport" in the street: self-defence, security and space in belle epoque Paris.

PubMed

Freundschuh, Aaron

2006-01-01

Near the turn of the twentieth century, traditional self-defence methods (for example, jiu-jitsu) were revamped into a more accessible and practical set of techniques and tactics for everyday use in urban public space. Framed as a "new sport" with broad public utility, early urban self-defence developed against the backdrop of heightening fears of violent crime and a burgeoning politics of security, as well as tensions provoked by the increasingly common appearance of unchaperoned, middle-class women in public. Self-defence masters pitched their innovations in an inclusive rhetoric, always with separate lessons for men and women and their respective spaces of risk. This article places modern self-defence practices in tension with historical transformations in the urban landscape, arguing that urban self-defence posited a certain subjective relation to the city that tapped simultaneously into the desire for empowerment, fantasies of criminal danger and a law-and-order tone that shaded into urban vigilantism.

Current and historical land use influence soil-based ecosystem services in an urban landscape.

PubMed

Ziter, Carly; Turner, Monica G

2018-04-01

Urban landscapes are increasingly recognized as providing important ecosystem services (ES) to their occupants. Yet, urban ES assessments often ignore the complex spatial heterogeneity and land-use history of cities. Soil-based services may be particularly susceptible to land-use legacy effects. We studied indicators of three soil-based ES, carbon storage, water quality regulation, and runoff regulation, in a historically agricultural urban landscape and asked (1) How do ES indicators vary with contemporary land cover and time since development? (2) Do ES indicators vary primarily among land-cover classes, within land-cover classes, or within sites? (3) What is the relative contribution of urban land-cover classes to potential citywide ES provision? We measured biophysical indicators (soil carbon [C], available phosphorus [P], and saturated hydraulic conductivity [K s ]) in 100 sites across five land-cover classes, spanning an ~125-year gradient of time since development within each land-cover class. Potential for ES provision was substantial in urban green spaces, including developed land. Runoff regulation services (high K s ) were highest in forests; water quality regulation (low P) was highest in open spaces and grasslands; and open spaces and developed land (e.g., residential yards) had the highest C storage. In developed land covers, both C and P increased with time since development, indicating effects of historical land-use on contemporary ES and trade-offs between two important ES. Among-site differences accounted for a high proportion of variance in soil properties in forests, grasslands, and open space, while residential areas had high within-site variability, underscoring the leverage city residents have to improve urban ES provision. Developed land covers contributed most ES supply at the citywide scale, even after accounting for potential impacts of impervious surfaces. Considering the full mosaic of urban green space and its history is needed to estimate the kinds and magnitude of ES provided in cities, and to augment regional ES assessments that often ignore or underestimate urban ES supply. © 2018 by the Ecological Society of America.

GODAN Local Farming Challenge 2017 - Encourage Geo-Innovation Solutions for Zero Hunger

NASA Astrophysics Data System (ADS)

Anand, Suchith; Hogan, Patrick; Brovelli, Maria; Schaap, Ben; Musker, Ruthie; Laperrière, André

2017-04-01

The initial ideas for Open Geospatial Science [1] were presented nearly a decade ago. They build upon the proposition of Open science which argues that scientific knowledge develops more rapidly and productively if openly shared (as early as is practical in the discovery process). The key ingredients that make Open Geospatial Science possible are enshrined in Open Principles, i.e.: open source geospatial software, open data, open standards, open educational resources, and open access to research publications. OpenCitySmart[2] is an initiative of Geo for All [3] that aims to develop a suite of tools for city-related infrastructure management (utilities, traffic, services, etc.). Its purpose will be to continually refine and add functionality that not only streamlines operational efficiency but also considers the need for sustainability and quality of urban life. OpenCitySmart employs Open solutions to build richer tools that empower organisations and individuals to utilizespatial and non-spatial data alike. This will create opportunities for innovation both globally and locally. As the population of cities grow, the concern of food security will shift from rural to urban areas. Currently, nearly 800 million people struggle with debilitating hunger and malnutrition and can be found in every corner of the globe. That's one in every nine people, with the majority being women and children. The Global Open Data for Agriculture and Nutrition (GODAN) [4] supports the proactive sharing of open data to make information about agriculture and nutrition available, accessible and usable to deal with the urgent challenge of ensuring world food security. A core principle behind GODAN is that a solution to Zero Hunger lies within existing, but often unavailable, agriculture and nutrition data. Through an online survey, GODAN found that the most needed data type across its 430+ partner network was geospatial data. Through the GODAN Europa Challenge we want to bring together researchers and students to work collaboratively on innovative ideas to create change using agriculture and nutrition data. The Europa Challenge is a World Challenge, though we use the wisdom of Europe's INSPIRE Directive to guide project development. The Europa Challenge is asking the world's *best and brightest* to deliver solutions serving city needs. With support from the NASA Europa Challenge[5], GODAN is launching a Local Farming Challenge. We welcome students to create innovative ideas that will help tackle the solutions of local farming in growing cities, using some aspect of the OpenCitySmart Design and uses NASA's open source virtual globe technology, WebWorldWind. Ideas may include ways for optimally linking local farming communities directly with potential customers, tools for visualising spatio-temporal aspects of local farming, tools for helping reducing wastage (for example linking with local food banks), and any number of solutions for helping our goal of Zero Hunger. 1. http://www.mdpi.com/journal/ijgi/special_issues/science-applications 2. http://www.geoforall.org/ 3. https://wiki.osgeo.org/wiki/Opencitysmart 4. http://www.godan.info 5. http://eurochallenge.como.polimi.it

The Effects of the Urban Built Environment on Mental Health: A Cohort Study in a Large Northern Italian City.

PubMed

Melis, Giulia; Gelormino, Elena; Marra, Giulia; Ferracin, Elisa; Costa, Giuseppe

2015-11-20

Mental health (MH) has a relevant burden on the health of populations. Common MH disorders (anxiety and non-psychotic depression) are well associated to socioeconomic individual and neighborhood characteristics, but little is known about the influence of urban structure. We analyzed among a Turin (Northwest Italy) urban population the association at area level of different urban structure characteristics (density, accessibility by public transport, accessibility to services, green and public spaces) and consumption of antidepressants. Estimates were adjusted by individual socio-demographic variables (education, housing tenure, employment) and contextual social environment (SE) variables (social and physical disorder, crime rates). Data was extracted from the Turin Longitudinal Study (TLS)-a census-based cohort study following up prospectively the mortality and morbidity of the population. As expected, individual characteristics show the strongest association with antidepressant drug consumption, while among built environment (BE) indicators accessibility by public transport and urban density only are associated to MH, being slightly protective factors. Results from this study, in agreement with previous literature, suggest that BE has a stronger effect on MH for people who spend more time in the neighborhood. Therefore, this research suggests that good accessibility to public transport, as well as a dense urban structure (versus sprawl), could contribute to reduced risk of depression, especially for women and elderly, by increasing opportunities to move around and have an active social life.

Privatization of local public hospitals: effect on budget, medical service quality, and social welfare.

PubMed

Aiura, Hiroshi; Sanjo, Yasuo

2010-09-01

We analyze a duopolistic health care market in which a rural public hospital competes against an urban public hospital on medical quality, by using a Hotelling-type spatial competition model extended into a two-region model. We show that the rural public hospital provides excess quality for each unit of medical service as compared to the first-best quality, and the profits of the rural public hospital are lower than those of the urban public hospital because the provision of excess quality requires larger expenditure. In addition, we investigate the impact of the partial (or full) privatization of local public hospitals.

Women in the city of man: recent contributions to the gender and human settlements debate.

PubMed

Rakodi, C

1996-02-01

This article reviews recent publications that add to the debate about gender and human settlements. Urban development is ultimately shaped by gender assumptions and by the way in which each sex experiences the urban environment; gender-blind urban planning can be overcome by reaching a greater understanding of women's economic and social roles (and the limitations imposed on them) in urban society. Most of the recent publications on women and human settlements have been produced for international conferences that have helped to mainstream gender issues and incorporate them into urban policy and practice. "Women in the City" is the report of the Organization for Economic Cooperation and Development's 1994 conference. Concerns raised in this report about the adverse effects a poorly designed living environment has on women, especially elderly women, are echoed in the proceedings of a 1992 international conference held at the University of Michigan, which considered issues of shelter policy, law, shelter and women in crisis, women's participation in the production of shelter, shelter and income opportunities, women and shelter-related services and infrastructure, nontraditional living arrangements, design, and the needs of elderly women. A 1994 publication edited by Meer contains a series of papers that analyze how women respond to urban poverty. Other recent publications focus on: 1) how women's work changes in response to economic development and urbanization, 2) survival strategies, 3) urban microenterprises, 4) gender analysis of land use and town planning, and 5) research and policy priorities that emerged from a 1994 conference held in Nairobi. In order to achieve social justice, gender issues must be analyzed along with issues such as age, ethnicity, and class.

[Urban construction, professions, and immigration at the origin of urban studies in Venezuela, 1870-1957].

PubMed

Martin Frechilla, J J

1996-01-01

The individuals and circumstances involved in the creation of the first graduate urban studies program in Venezuela are recalled, beginning with the odernization of Caracas under the impulse of President Antonio Guzman Blanco, elected in 1870. Guzman Blanco converted himself into Venezuela's first urbanist with the establishment of organizational frameworks and completion of massive public works projects, which were based largely on the urban models of the US and Europe. Engineering and public health were consolidated as the two most influential sources of professional competence for guiding urban development. By the mid-1930s, growth fueled by petroleum revenues was causing rapid urbanization, and it became apparent that trained professionals able to manage the increasingly complex tasks of urban planning were in short supply. A new surge of modernizing construction began in 1936 and led to a cooperative arrangement with a French firm, whose personnel were to be required to train Venezuelan engineers for future service in urban planning. An influx of refugees from the Spanish Civil War and the increasing influence of urban planning processes in the US were also observed. The National Commission on Urbanism was created in 1946 as a dependency of the Ministry of Planning to facilitate public administration of the development and control of cities. Throughout the period, a debate was underway on the need for a multidisciplinary approach to urban planning versus a primarily architectural or engineering approach. In 1957, some consensus was reached on the need for urban planning to be viewed as more than a speciality of architecture. A framework was developed for a graduate program in 1969 in the Central University of Venezuela. The National Commission on Urbanism was disbanded in 1957, largely because of its excessive focus on architecture to the exclusion of other disciplines relevant to the urbanization process.

Urbanization and health in China, thinking at the national, local and individual levels.

PubMed

Li, Xinhu; Song, Jinchao; Lin, Tao; Dixon, Jane; Zhang, Guoqin; Ye, Hong

2016-03-08

China has the biggest population in the world, and has been experiencing the largest migration in history, and its rapid urbanization has profound and lasting impacts on local and national public health. Under these conditions, a systems understanding on the correlation among urbanization, environmental change and public health and to devise solutions at national, local and individual levels are in urgent need. In this paper, we provide a comprehensive review of recent studies which have examined the relationship between urbanization, urban environmental changes and human health in China. Based on the review, coupled with a systems understanding, we summarize the challenges and opportunities for promoting the health and wellbeing of the whole nation at national, local, and individual levels. Urbanization and urban expansion result in urban environmental changes, as well as residents' lifestyle change, which can lead independently and synergistically to human health problems. China has undergone an epidemiological transition, shifting from infectious to chronic diseases in a much shorter time frame than many other countries. Environmental risk factors, particularly air and water pollution, are a major contributing source of morbidity and mortality in China. Furthermore, aging population, food support system, and disparity of public service between the migrant worker and local residents are important contributions to China's urban health. At the national level, the central government could improve current environmental policies, food safety laws, and make adjustments to the health care system and to demographic policy. At the local level, local government could incorporate healthy life considerations in urban planning procedures, make improvements to the local food supply, and enforce environmental monitoring and management. At the individual level, urban residents can be exposed to education regarding health behaviour choices while being encouraged to take responsibility for their health and to participate in environmental monitoring and management.

Transformation of the Urban Health Care Safety Net: The Devolution of a Public Responsibility.

PubMed

Kulesher, Robert

2015-01-01

Reduced spending in both federal and state programs and the closure of public hospitals have serious consequences for the health of urban dwellers, especially the poor and uninsured. Through a combination of economic factors, many municipalities have formed public-private partnerships and launched community initiatives to preserve some of the elements of the health care safety net. What once was a responsibility of municipal governments, the provision of health care to poor and uninsured populations, is now posing challenges for private-sector providers. This article identifies several factors that have contributed to the incremental demise of the publicly funded urban health care safety net and how local entities and the federal government are responding to the care of the poor and uninsured.

Space evolution model and empirical analysis of an urban public transport network

NASA Astrophysics Data System (ADS)

Sui, Yi; Shao, Feng-jing; Sun, Ren-cheng; Li, Shu-jing

2012-07-01

This study explores the space evolution of an urban public transport network, using empirical evidence and a simulation model validated on that data. Public transport patterns primarily depend on traffic spatial-distribution, demands of passengers and expected utility of investors. Evolution is an iterative process of satisfying the needs of passengers and investors based on a given traffic spatial-distribution. The temporal change of urban public transport network is evaluated both using topological measures and spatial ones. The simulation model is validated using empirical data from nine big cities in China. Statistical analyses on topological and spatial attributes suggest that an evolution network with traffic demands characterized by power-law numerical values which distribute in a mode of concentric circles tallies well with these nine cities.

Zhang, Qian; Perra, Nicola; Gonçalves, Bruno; Ciulla, Fabio; Vespignani, Alessandro

2013-01-01

We analyze the entire publication database of the American Physical Society generating longitudinal (50 years) citation networks geolocalized at the level of single urban areas. We define the knowledge diffusion proxy, and scientific production ranking algorithms to capture the spatio-temporal dynamics of Physics knowledge worldwide. By using the knowledge diffusion proxy we identify the key cities in the production and consumption of knowledge in Physics as a function of time. The results from the scientific production ranking algorithm allow us to characterize the top cities for scholarly research in Physics. Although we focus on a single dataset concerning a specific field, the methodology presented here opens the path to comparative studies of the dynamics of knowledge across disciplines and research areas.

Microscale Obstacle Resolving Air Quality Model Evaluation with the Michelstadt Case

PubMed Central

Rakai, Anikó; Kristóf, Gergely

2013-01-01

Modelling pollutant dispersion in cities is challenging for air quality models as the urban obstacles have an important effect on the flow field and thus the dispersion. Computational Fluid Dynamics (CFD) models with an additional scalar dispersion transport equation are a possible way to resolve the flowfield in the urban canopy and model dispersion taking into consideration the effect of the buildings explicitly. These models need detailed evaluation with the method of verification and validation to gain confidence in their reliability and use them as a regulatory purpose tool in complex urban geometries. This paper shows the performance of an open source general purpose CFD code, OpenFOAM for a complex urban geometry, Michelstadt, which has both flow field and dispersion measurement data. Continuous release dispersion results are discussed to show the strengths and weaknesses of the modelling approach, focusing on the value of the turbulent Schmidt number, which was found to give best statistical metric results with a value of 0.7.

Towns concentrate around 50% of world-wide population and the trend is oriented to underscore an urban profile of population. In addition, towns have become important for their economic contribution to the Gross Internal Product. The negative side of towns is the environmental and social impacts as a result of productive and domestic activities, besides the lack of available data. In order to overcome these shortcomings, the United Nations has established a project of urban monitoring throughout the Global Network of Urban Observatories; Mexico joined the project in 2005. The Local Urban Observatory of Mexicali has the task to produce information about cities that is useful to design public policies. Some of this information deals with a set of environmental indicators in the United Nations Habitat Agenda, which includes solid wastes. Therefore, this paper deals with two main topics; firstly, from the Habitat Agenda, a comparative urban analysis of waste production and coverage of domestic waste collection services; secondly, from the Local Agenda, the identification and ranking of environmental problems according to public perception coming from people involved in the municipal planning and decision making process. Results will be used to develop local indicators and public environmental policies.

  Marginalization is a significant issue in Mexico, involving a lack of access to health services with differential impacts on Indigenous, rural and urban populations. The objective of this study was to understand Mexico’s public health problem across three population areas, Indigenous, rural and urban, in relation to degree of marginalization and health service coverage.   The sampling universe of the study consisted of 107 458 geographic locations in the country. The study was retrospective, comparative and confirmatory. The study applied analysis of variance, parametric and non-parametric, correlation and correspondence analyses.   Significant differences were identified between the Indigenous, rural and urban populations with respect to their level of marginalization and access to health services. The most affected area was Indigenous, followed by rural areas. The sector that was least affected was urban.   Although health coverage is highly concentrated in urban areas in Mexico, shortages are mostly concentrated in rural areas where Indigenous groups represent the extreme end of marginalization and access to medical coverage. Inadequate access to health services in the Indigenous and rural populations throws the gravity of the public health problem into relief.

Throughout the developing world, urban centres with sprawling slum settlements are rapidly expanding and invading previously forested ecosystems. Slum communities are characterized by untended refuse, open sewers and overgrown vegetation, which promote rodent infestation. Norway rats (Rattus norvegicus) are reservoirs for epidemic transmission of many zoonotic pathogens of public health importance. Understanding the population ecology of R. norvegicus is essential to formulate effective rodent control strategies, as this knowledge aids estimation of the temporal stability and spatial connectivity of populations. We screened for genetic variation, characterized the population genetic structure and evaluated the extent and patterns of gene flow in the urban landscape using 17 microsatellite loci in 146 rats from nine sites in the city of Salvador, Brazil. These sites were divided between three neighbourhoods within the city spaced an average of 2.7 km apart. Surprisingly, we detected very little relatedness among animals trapped at the same site and found high levels of genetic diversity, as well as structuring across small geographical distances. Most F(ST) comparisons among sites were statistically significant, including sites <400 m apart. Bayesian analyses grouped the samples in three genetic clusters, each associated with distinct sampling sites from different neighbourhoods or valleys within neighbourhoods. These data indicate the existence of complex genetic structure in R. norvegicus in Salvador, linked to the heterogeneous urban landscape. Future rodent control measures need to take into account the spatial and temporal linkage of rat populations in Salvador, as revealed by genetic data, to develop informed eradication strategies. © 2013 John Wiley & Sons Ltd.

Land surface albedo is a key parameter controlling the local energy budget, and altering the albedo of built surfaces has been proposed as a tool to mitigate high near-surface temperatures in the urban heat island. However, most research on albedo in urban landscapes has used coarse-resolution data, and few studies have attempted to relate albedo to other urban land cover characteristics. This study provides an empirical description of urban summertime albedo using 30 m remote sensing measurements in the metropolitan area around Boston, Massachusetts, relating albedo to metrics of impervious cover fraction, tree canopy coverage, population density, and land surface temperature (LST). At 30 m spatial resolution, median albedo over the study area (excluding open water) was 0.152 (0.112-0.187). Trends of lower albedo with increasing urbanization metrics and temperature emerged only after aggregating data to 500 m or the boundaries of individual towns, at which scale a -0.01 change in albedo was associated with a 29 (25-35)% decrease in canopy cover, a 27 (24-30)% increase in impervious cover, and an increase in population from 11 to 386 km-2. The most intensively urbanized towns in the region showed albedo up to 0.035 lower than the least urbanized towns, and mean mid-morning LST 12.6°C higher. Trends in albedo derived from 500 m Moderate Resolution Imaging Spectroradiometer (MODIS) measurements were comparable, but indicated a strong contribution of open water at this coarser resolution. These results reveal linkages between albedo and urban land cover character, and offer empirical context for climate resilient planning and future landscape functional changes with urbanization.

The Urban Development Corporation (UDC) is one of the biggest implementation bodies for urban development in Japan. UDC has developed rainwater infiltration technology since 1975. This technology has effectively reduced runoff to a river and sewer system in the new town project areas. Recently, UDC has developed a new system which is defined as a "Rainwater Recycle Sewer System", which is supported by "Rainwater Storage and Infiltration Technology (RSIT)" applicable to new town creation and urban renewal. The new system consists of two elements: RSIT components based on Public-Private Partnership (PPP) and a stormwater drainage system. Herein, the private sector is responsible for the main part of RSIT, and the public sector is responsible for the stormwater drainage from the development area. As a result, the capacity of public facilities, such as rainwater sewers and stormwater reservoirs, can be reduced effectively. In parallel, the initial/running cost of public facilities is expected to be reduced. In conclusion, the authors would stress the importance of a co-maintenance system also based on PPP, which will be required especially in order to properly operate the whole system for the long term.

Terrorists have threatened and carried out chemicalhiological agent attacks on targets in major cities. The nerve agent sarin figured prominently in one well-publicized incident. Vapors disseminating from open containers in a Tokyo subway caused thousands of casualties. High-resolution tracer transport modeling of agent dispersion is at hand and will be enhanced by data on reactions with components of the urban atmosphere. As a sample of the level of complexity currently attainable, we elaborate the mechanisms by which sarin can decompose in polluted air. A release scenario is outlined involving the passage of a gas-phase agent through a city locale inmore » the daytime. The atmospheric chemistry database on related organophosphorus pesticides is mined for rate and product information. The hydroxyl,radical and fine-mode particles are identified as major reactants. A review of urban air chernistry/rnicrophysics generates concentration tables for major oxidant and aerosol types in both clean and dirty environments. Organic structure-reactivity relationships yield an upper limit of 10-1' cm3 molecule-' S-* for hydrogen abstraction by hydroxyl. The associated midday loss time scale could be as little as one hour. Product distributions are difficult to define but may include nontoxic organic oxygenates, inorganic phosphorus acids, sarin-like aldehydes, and nitrates preserving cholinergic capabilities. Agent molecules will contact aerosol surfaces in on the order of minutes, with hydrolysis and side-chain oxidation as likely reaction channels.« less

The objective was to determine secondhand smoke (SHS) exposure with and without smoke-free laws in urban and rural communities. The research hypothesis was that SHS exposure in public places could be improved by smoke-free law regardless of urban and rural status. Indoor air quality in hospitality venues was assessed in 53 communities (16 urban and 37 rural) before smoke-free laws; 12 communities passed smoke-free laws during the study period. Real-time measurements of particulate matter with 2.5 µm aerodynamic diameter or smaller (PM2.5) were taken 657 times from 586 distinct venues; about 71 venues had both pre- and post-law measurements. Predictors of log-transformed PM2.5 level were determined using multilevel modeling. With covariates of county-level percent minority population, percent with at least high school education, adult smoking rate, and venue-level smoker density, indoor air quality was associated with smoke-free policy status and venue type and their interaction. The geometric means for restaurants, bars, and other public places in communities without smoke-free policies were 22, 63, and 25 times higher than in those with smoke-free laws, respectively. Indoor air quality was not associated with urban status of venue, and none of the interactions involving urban status were significant. SHS exposure in public places did not differ by urban/rural status. Indoor air quality was associated with smoke-free law status and venue type. This study analyzed 657 measurements of indoor PM2.5 level in 53 communities in Kentucky, USA. Although indoor air quality in public places was associated with smoke-free policy status and venue type, it did not differ by urban and rural status. The finding supports the idea that population in rural communities can be protected with smoke-free policy. Therefore, it is critical to implement smoke-free policy in rural communities as well as urban areas.

Cholera is endemic in Bangladesh with epidemics occurring each year. The decision to use a cheap oral killed whole-cell cholera vaccine to control the disease depends on the feasibility and effectiveness of vaccination when delivered in a public health setting. We therefore assessed the feasibility and protective effect of delivering such a vaccine through routine government services in urban Bangladesh and evaluated the benefit of adding behavioural interventions to encourage safe drinking water and hand washing to vaccination in this setting. We did this cluster-randomised open-label trial in Dhaka, Bangladesh. We randomly assigned 90 clusters (1:1:1) to vaccination only, vaccination and behavioural change, or no intervention. The primary outcome was overall protective effectiveness, assessed as the risk of severely dehydrating cholera during 2 years after vaccination for all individuals present at time of the second dose. This study is registered with ClinicalTrials.gov, number NCT01339845. Of 268,896 people present at baseline, we analysed 267,270: 94,675 assigned to vaccination only, 92,539 assigned to vaccination and behavioural change, and 80,056 assigned to non-intervention. Vaccine coverage was 65% in the vaccination only group and 66% in the vaccination and behavioural change group. Overall protective effectiveness was 37% (95% CI lower bound 18%; p=0·002) in the vaccination group and 45% (95% CI lower bound 24%; p=0·001) in the vaccination and behavioural change group. We recorded no vaccine-related serious adverse events. Our findings provide the first indication of the effect of delivering an oral killed whole-cell cholera vaccine to poor urban populations with endemic cholera using routine government services and will help policy makers to formulate vaccination strategies to reduce the burden of severely dehydrating cholera in such populations.

Adaptive Correlation Space Adjusted Open-Loop Tracking Approach for Vehicle Positioning with Global Navigation Satellite System in Urban Areas

2015-01-01

For vehicle positioning with Global Navigation Satellite System (GNSS) in urban areas, open-loop tracking shows better performance because of its high sensitivity and superior robustness against multipath. However, no previous study has focused on the effects of the code search grid size on the code phase measurement accuracy of open-loop tracking. Traditional open-loop tracking methods are performed by the batch correlators with fixed correlation space. The code search grid size, which is the correlation space, is a constant empirical value and the code phase measuring accuracy will be largely degraded due to the improper grid size, especially when the signal carrier-to-noise density ratio (C/N0) varies. In this study, the Adaptive Correlation Space Adjusted Open-Loop Tracking Approach (ACSA-OLTA) is proposed to improve the code phase measurement dependent pseudo range accuracy. In ACSA-OLTA, the correlation space is adjusted according to the signal C/N0. The novel Equivalent Weighted Pseudo Range Error (EWPRE) is raised to obtain the optimal code search grid sizes for different C/N0. The code phase measuring errors of different measurement calculation methods are analyzed for the first time. The measurement calculation strategy of ACSA-OLTA is derived from the analysis to further improve the accuracy but reduce the correlator consumption. Performance simulation and real tests confirm that the pseudo range and positioning accuracy of ASCA-OLTA are better than the traditional open-loop tracking methods in the usual scenarios of urban area.

Built environment studies provide broad evidence that urban characteristics influence physical activity (PA). However, findings are still difficult to compare, due to inconsistent measures assessing urban point characteristics and varying definitions of spatial scale. Both were found to influence the strength of the association between the built environment and PA. We simultaneously evaluated the effect of kernel approaches and network-distances to investigate the association between urban characteristics and physical activity depending on spatial scale and intensity measure. We assessed urban measures of point characteristics such as intersections, public transit stations, and public open spaces in ego-centered network-dependent neighborhoods based on geographical data of one German study region of the IDEFICS study. We calculated point intensities using the simple intensity and kernel approaches based on fixed bandwidths, cross-validated bandwidths including isotropic and anisotropic kernel functions and considering adaptive bandwidths that adjust for residential density. We distinguished six network-distances from 500 m up to 2 km to calculate each intensity measure. A log-gamma regression model was used to investigate the effect of each urban measure on moderate-to-vigorous physical activity (MVPA) of 400 2- to 9.9-year old children who participated in the IDEFICS study. Models were stratified by sex and age groups, i.e. pre-school children (2 to <6 years) and school children (6-9.9 years), and were adjusted for age, body mass index (BMI), education and safety concerns of parents, season and valid weartime of accelerometers. Association between intensity measures and MVPA strongly differed by network-distance, with stronger effects found for larger network-distances. Simple intensity revealed smaller effect estimates and smaller goodness-of-fit compared to kernel approaches. Smallest variation in effect estimates over network-distances was found for kernel intensity measures based on isotropic and anisotropic cross-validated bandwidth selection. We found a strong variation in the association between the built environment and PA of children based on the choice of intensity measure and network-distance. Kernel intensity measures provided stable results over various scales and improved the assessment compared to the simple intensity measure. Considering different spatial scales and kernel intensity methods might reduce methodological limitations in assessing opportunities for PA in the built environment.
