How might we begin to explore the concept of the &amp;#8220;sustainable city&amp;#8221; in a world often characterized as dynamic, fluid, and contested? Debates about the sustainable city are too often dominated by a technological discourse conducted among professional experts, but this technocratic framing is open to challenge. For some critics, sustainability is a meaningless notion, yet for others its semantic pliability opens up discursive spaces through which to explore interconnections across time, space, and scale. Thus, while enacting sustainability in policy and practice is an arduous task, we can productively ask how cultural imaginations might be stirred and shaken to make sustainability accessible to a wider public who might join the...

Fulton School of Engineering, Arizona State University ;.
Popular concern over water quality has important implications for public water management because it can both empower water utilities to improve service but also limit their ability to make changes. In the desert city of Phoenix, Arizona, obtaining sufficient high-quality water resources for a growing urban population poses a major challenge. Decision makers and urban hydrologists are aware of these challenges to water sustainability but the range of acceptable policy and management options available to them is constrained by public opinion. Therefore, this study examines cultural models of water quality and water management, termed ethnohydrology, among urban residents. The study yields three key findings. First, urban residents appear to have a shared...

Neighborhood change and the role of environmental stewardship: a case study of green infrastructure for stormwater in the City of Portland, Oregon, USA
Provedor de dados: 7
Autores: Shandas, Vivek; Toulan School of Urban Studies and Planning, Portland State University; Sustaining Urban Places Research Lab; vshandas@pdx.edu.
Throughout the history of cities, the ecological landscape has often been buried, removed, or taken for granted. A recent recognition that humans are part of the global ecosystem, and that human actions both cause and are affected by ecological change, brings with it an awareness of the value of nature in cities and of natural systems on which cities depend. The feedbacks between humans and their environment within an urban context can have profound implications for the growth of and change in cities, yet there is a limited understanding of the interactions between biophysical changes in cities and the implications of these changes on the quality of life for residents. The application of a coupled human and natural systems (CHANS) framework provides a...

Our aim was to explore the use of practice theory as an approach to studying urban environmental stewardship. Urban environmental stewardship, or civic ecology practice, contributes to ecosystem services and community well-being and has been studied using social-ecological systems resilience, property rights, communities of practice, and governance frameworks. Practice theory, which previously has been applied in studies of consumer behaviors, adds a new perspective to urban stewardship research, focusing on how elements of a practice, such as competencies, meanings, and physical resource, together define the practice. We applied practice theory to eight different civic ecology practices, including oyster gardening in New York City, a civil society group...

The problem of spatial fit in social-ecological systems: detecting mismatches between ecological connectivity and land management in an urban region
Provedor de dados: 7
Autores: Bergsten, Arvid; Stockholm Resilience Centre, Stockholm University; arvid.bergsten@su.se; Galafassi, Diego; Stockholm Resilience Centre, Stockholm University; diego.galafassi@su.se.
The problem of institutional fit in social-ecological systems has been empirically documented and conceptually discussed for decades, yet there is a shortage of approaches to systematically and quantitatively examine the level of fit. We address this gap, focusing on spatial fit in an urban and peri-urban regional landscape. Such landscapes typically exhibit significant fragmentation of remnant habitats, which can limit critical species dispersal. This may have detrimental effects on species persistence and ecosystem functioning if land use is planned without consideration of the spatial patterns of fragmentation. Managing habitat fragmentation is particularly challenging when the scale of fragmentation reaches beyond the control of single managers,...

Socioeconomic drivers of yard sustainable practices in a tropical city
Provedor de dados: 7
A growing body of work has emphasized the importance of residential areas to the overall green infrastructure of cities and recognizes that outcomes related to these areas are best studied using a social-ecological approach.  We conducted vegetation surveys to evaluate yard practices that relate to the state of the yard vegetation, including species diversity and abundance, vegetation structure, and the percent of green area of yards versus paved areas, at the R&amp;#237;o Piedras watershed within the San Juan metropolitan area. We used concomitant social household surveys to evaluate the association of social-economic and demographic factors at the household scale with these vegetation characteristics, as well as with landscape-level characteristics...

Closing the Gap: Communicating to Change Gardening Practices in Support of Native Biodiversity in Urban Private Gardens
Provedor de dados: 7
Autores: van Heezik, Yolanda M; University of Otago; yolanda.vanheezik@otago.ac.nz; Dickinson, Katharine J. M.; University of Otago; kath.dickinson@botany.otago.ac.nz; Freeman, Claire; University of Otago; cf@geography.otago.ac.nz.
Private gardens collectively comprise the largest green space in most cities and the greatest potential for increasing the extent of wildlife-friendly and native-dominated habitat, improving the quality of ecosystem services, and providing opportunities for urban dwellers to reconnect with nature. Because attitudes and values driving landscape preferences in gardens are complex and often not conducive to biodiversity, and a gap exists between the possession of knowledge or values and the expression of pro-environmental behavior, facilitating change in gardening behavior is challenging. We attempted to improve knowledge and influence values, attitudes, and gardening behavior of 55 householders in favor of native biodiversity and environmentally friendly...

Rural Broadband At A Glance, 2009 Edition
Provedor de dados: 31
Autores: Stenberg,   Peter L.; Low,   Sarah A.
Three-quarters of U.S. residents used the Internet to access information, education, and services in 2007. Broadband Internet access is becoming essential for both businesses and households; many compare its evolution to other technologies now considered common necessities—such as cars, electricity, televisions, microwave ovens, and cell phones. Although rural residents enjoy widespread access to the Internet, they are less likely to have high-speed, or broadband, Internet access than their urban counterparts. Circumstantial evidence suggests that the difference in access may lie in the higher cost and limited availability of broadband Internet in rural areas. As a result, rural residents depend more on Internet use outside of the home, in places like the...

AGRICULTURAL RESEARCH AND URBAN POVERTY IN INDIA
Provedor de dados: 31
Autores: Fan,   Shenggen.
Using a similar analytical approach to a study in China, this paper analyzes the impact of agricultural research on urban poverty reduction in India. State level data from 1970 to 1995 were used in the empirical analysis. It is found that in addition to its large impact on rural poverty reduction, agricultural research investments have also played a major role in the reduction of urban poverty. Agricultural research investments increase agricultural production, and increased production in turn lowers food prices. The urban poor often benefit proportionately more than the non-poor since they spend 50-80% of their income on food. Among all the rural investments considered in this study, agricultural research has the largest impact on urban poverty reduction...

Market Institutions: Enhancing the Value of Rural-Urban Links
Provedor de dados: 31
Autores: Chowdhury,   Shyamal K.; Negassa,   Asfaw; Torero,   Maximo.
This paper examines how market institutions can affect links between urban and rural areas with specific emphasis on goods market integration in the national context. Traditionally, development researchers and practitioners have focused either on rural market development or on urban market development without considering the interdependencies and synergies between the two. However, more than ever before, emerging local and global patterns such as the modern food value-chain led by supermarkets and food processors, rapid urbanization, changes in dietary composition, and enhanced information and communication technologies point to the need to pay close attention to the role of markets both in linking rural areas with intermediate cities and market towns and...

Experiments with regulations &amp; markets linking upstream tree plantations with downstream water users
Provedor de dados: 31
Autores: Nordblom,   Thomas L.; Reeson,   Andrew; Finlayson,   John D.; Hume,   Iain H.; Whitten,   Stuart M.; Kelly,   Jason A.
Land-use change in upper catchments impact downstream water flows. As trees use large amounts of water the expansion of upstream plantations can substantially reduce water availability to downstream users. There can also be impacts on downstream salinity due to reduced dilution flows. In some jurisdictions afforestation requires the purchase of water rights from downstream holders, while in others it does not, effectively handing the water rights to the upstream landholders. We consider the economic efficiency and equity (profitability and distributional) consequences of upstream land use change in the presence of a water market under alternate property rights regimes and different salinity scenarios.

As broadband—or high-speed—Internet use has spread, Internet applications requiring high transmission speeds have become an integral part of the “Information Economy,” raising concerns about those who lack broadband access. This report analyzes (1) rural broadband use by consumers, the community-at-large, and businesses; (2) rural broadband availability; and (3) broadband’s social and economic effects on rural areas. It also summarizes results from an ERS-sponsored workshop on rural broadband use, and other ERS-commissioned studies. In general, rural communities have less broadband Internet use than metro communities, with differing degrees of broadband availability across rural communities. Rural communities that had greater broadband Internet access had...

Urban Demand for Edible Oils and Fats in China: Evidence from Household Survey Data
Provedor de dados: 31
Autores: Fang,   Cheng; Beghin,   John C.
Using urban household-level survey data from 1992 to 1998, we provide estimates of final demand for edible vegetable oils and animal fats in three regions of China based on the LinQuad incomplete demand system. For each region, the demand for the major "staple" oil is price inelastic. The demand for "condiment" or flavoring oils is more price responsive. All edible oils and fats have positive income elasticity, but smaller than one. Using the LinQuad parameter estimates, we provide exact measures of urban consumer  welfare losses associated with trade restrictions on vegetable oil imports. Consumers suffer a significant welfare loss of the order of $ 392 million (1998 dollars).

HOW AGRICULTURAL RESEARCH AFFECTS URBAN POVERTY IN DEVELOPING COUNTRIES: THE CASE OF CHINA
Provedor de dados: 31
Autores: Fan,   Shenggen; Fang,   Cheng; Zhang,   Xiaobo.
This paper develops a framework to measure the impact of agricultural research on urban poverty. Increased investments in agricultural R&amp;D can lower food prices by increasing food production, and lower food prices benefit the urban poor because they often spend more than 60% of their income on food. Application of the framework to China shows that these food price effects are large and that the benefits for the urban poor have been about as large as the benefits for the rural poor.

DEMAND FOR FOOD QUANTITY AND QUALITY IN CHINA
Provedor de dados: 31
Autores: Gale,   H. Frederick, Jr.; Huang,   Kuo S.
As their incomes rise, Chinese consumers are changing their diets and demanding greater quality, convenience, and safety in food. Food expenditures grow faster than quantities purchased as income rises, suggesting that consumers with higher incomes purchase more expensive foods. The top-earning Chinese households appear to have reached a point where the income elasticity of demand for quantity of most foods is near zero. China’s food market is becoming segmented. The demand for quality by high-income households has fueled recent growth in modern food retail and sales of premium-priced food and beverage products. Food expenditures and incomes have grown much more slowly for rural and low-income urban households.

Migration and the Rural-Urban Continuum: Evidence from the Rural Philippines
Provedor de dados: 31
Autores: Quisumbing,   Agnes R.; McNiven,   Scott.
Migration is an important livelihood strategy in the Philippines. In 1991, 26 percent of urban households and 13 percent of rural households received remittances from migrant parents or children. Although international migration has received more attention than internal migration, the latter is significant in the Philippines. Between 1980 and 1990, the number of persons over the age of five years who were not resident in the city or municipality they resided in five years ago, increased from 2.85 to 3.24 million. Recent migration flows are interprovincial, typically in the direction of Metropolitan Manila and surrounding areas, and are dominated by women. While the percentage of the population classified as urban increased from 36 percent in the mid-1970s...

Why Do Rural Firms Live Longer?
Provedor de dados: 31
Autores: Yu,   Li; Orazem,   Peter F.; Jolly,   Robert W.
Rural firms have a higher survival rate than urban firms. Over the first 13 years after firm entry, the hazard rate for firm exits is persistently higher for urban firms. While differences in firm attributes explain some of the rural-urban gap in firm survival, rural firms retain a survival advantage 18.5% greater than observationally equivalent urban firms. We argue that in competitive markets, the remaining survival advantage for rural firms must be attributable to unobserved factors that must be known at the time of entry. A plausible candidate for such a factor is thinner markets for the capital of failed rural firms. The implied lower salvage value of rural firms suggests that firms sorting into rural markets must have a higher probability of success...

• The Zambia Urban Consumption Survey, a survey of 1,865 urban households in Lusaka, Kitwe, Mansa, and Kasama, was conducted in August 2007 and February 2008 by the Central Statistical Office in collaboration with the Zambia Food Security Research Project. • Survey results indicate that in Lusaka and Kitwe, wheat has overtaken maize as the most important staple in terms of urban consumer expenditures. Maize is no longer the dominant staple food in urban Zambia, except among the poor. This finding is consistent with broader regional trends toward declining dependence on maize for urban staple food needs. • Hammer-milling services are readily available to the vast majority of urban households and in most cases their cheapest maize meal option is to obtain...

Factors affecting escape distance in birds
Provedor de dados: 103
Autores: Piratelli,Augusto J.; Favoretto,Gabriela R.; Maximiano,Marina F. de Almeida.
ABSTRACT The flight initiation distance has been used either to understand the cost-benefit trade-offs related to the risk of predation or as an important tool for wildlife managers. Although this variable is well-discussed for temperate regions, it is still poorly known in the Neotropics. Here we analyze the escape behavior of birds from southeastern Brazil, comparing an urban to a non-urban area. We tested for the influence of sites (urban vs. non-urban area), approaching (by one vs. two people), daytime (morning vs. afternoon), seasons (breeding vs. non-breeding) and body mass on the determination of the initial (FID) and final (FFD) flight distances across different bird species. We predict that FID will be greater in rural areas and under a greater...

ABSTRACT  A cross sectional study was conducted in two types of respiratory patients in hospital population. It was found that tuberculosis (T.B) was the most common type (29.66%) followed by the asthma (28.08%) and chronic obstructive pulmonary disease (COPD) (11.31%). Average age of diagnosis was 42.15 ± 0.65 years and average age at present 47.99 ± 0.70 years. Age group 51-60 years was more prone to this disease (21.13%). Most of the patients were married (80.06%). The highest representation of patients with respiratory diseases was observed in 1st birth order (30.36%) followed by 2nd (26.49%) and 3rd (18.45%), while the lowest was in 10th birth order (0.40%).

ABSTRACT  Background: Dai is a major Chinese ethnic minority group residing in rural areas of the southern part of Yunnan. However, no data exist on the Human Papillomavirus (HPV) prevalence and genotype distribution among Dai women.  Method: A total of 793 participants (Dai = 324, Han = 251, other ethnic = 218) were included in this study. PCR was performed to detect the HPV-positive samples, and genotyping was performed with an HPV Geno-Array.  Result: The overall HPV prevalence was very low among Dai women compared to the others. The prevalence of high-risk-HPV infections was significantly higher (p = 0.001) among other ethnic women (22.0%) than that among Han (13.1%) and Dai women (7.1%). The overall HPV, high-risk-HPV, single and multiple infection...
