Disparities in access to healthy food are a key public health concern in the United States (U.S.) Food access is considered as a critical element of food insecurity. Food insecurity can often be prevalent in a region due to lack of healthy food outlets as well as inequitable access to healthy food outlets. A large body of literature pertaining to access to healthy food has reported that conventional food outlets such as supermarkets and large grocery stores may not be equitably distributed across different neighborhoods in a region. There has been limited research on local food access patterns. Despite the few studies focused on access to individual types of local food outlets, such as farmers markets, little is known about whether such access varies among different types of local food outlets and how such access patterns compare with the uneven access to conventional food outlets. This study uses Maricopa County, one of the largest counties in Arizona, as a case study to examine the spatial patterns of access to conventional food markets (i.e. supermarkets or large grocery stores) and four different types of local food outlets, including farmers market, community garden, community supported agriculture (CSA) and mobile food markets. By analyzing the association between healthy food access and neighborhood characteristics, the study suggests that the local food system has a great potential in providing healthy food access to low-income and minority populations of the County than conventional food outlets. The study provides important insights into the way different types of local food outlets offer their availability in space and whether they are more equitable in serving underserved neighborhoods. The findings from this study can assist both government agencies and city planner formulate strategies to improve access to healthy food in disadvantaged neighborhoods.
This study identifies flexibility and accountability as two important characteristics of the Chinese governance context, and traces how they affect stakeholder behavior and coalition formation, which in turn impacts policy implementation performance. The case study methodology triangulates analysis of government policy documents, secondary data, and the results of semi-structured key informant interviews.
Findings include: (i) The Chinese government has a very strong implementation capability to pass directives down and scale up, enabling rapid accomplishment of massive goals. It also has the capability to decide how the market should come into play, and to shape public opinion and ignore opposition; (ii) Interventions from the authoritarian government, given China’s vast economy and market, and the efficient top-down tiered bureaucratic system, risk distorting the market and the real policy goals during the implementation process; (iii) There tends to be an absence of bottom-up participation and feedback mechanisms; (iv) An effective self-correction mechanism, associated with flexibility and adaptability by a myriad of stakeholders often enables effective policy adjustment.
Policy implications include: (i) Policy implementation concerns need to be integrated into policy design; (ii) More thorough discussion of options is required during policy design; (iii) Better communication channels and instruments are needed to provide feedback from the bottom-up; (iv) On complex policy issues such as air pollution, pilot projects should be carried out before massive adoption of a policy.
The study presented in this article adds to the body of research on the socio-cultural dimension of sustainable cities by looking at the efforts of the City of Freiburg, Germany to create neighborhoods that acknowledge the importance of the social dimension of sustainable development. The research in this article is centered on evaluating the social responses of living in Freiburg’s two recognized sustainable neighborhoods Rieselfeld and Vauban. The study focuses on the motivational factors that prompted todays residents of the two neighborhoods to move there in the first place, their level of satisfaction living there now, and their perceived social interactions and level of community engagement. Result show that satisfaction with living in a place and reinforcing its assets through social resiliency or livability can result in long-term community staying power. In general, there were few differences in preferences ratings of physical and social assets between the two communities. The levels of importance of social factors contributing to place satisfaction and staying power were not significantly different in both neighbor-hoods. Having a “cluster” of social factors present that were important to residents contributed significantly to place satisfaction. In fact, survey results showed that it was these social factors that were seen as more important to place satisfaction than the physical attributes of sustainable developments.
This dissertation focuses on solar PV development at three different spatial planning levels: the state level (state of Arizona); the metropolitan level (Phoenix Metropolitan Statistical Area); and the city level. At the State level, this thesis answers how much suitable land is available for utility-scale PV development and how future land cover changes may affect the availability of this land. Less than two percent of Arizona's land is considered Excellent for PV development, most of which is private or state trust land. If this suitable land is not set-aside, Arizona would then have to depend on less suitable lands, look for multi-purpose land use options and distributed PV deployments to meet its future energy need.
At the Metropolitan Level, ‘agrivoltaic’ system development is proposed within Phoenix Metropolitan Statistical Area. The study finds that private agricultural lands in the APS (Arizona Public Service) service territory can generate 3.4 times the current total energy requirements of the MSA. Most of the agricultural land lies within 1 mile of the 230 and 500 kV transmission lines. Analysis shows that about 50% of the agricultural land sales would have made up for the price of the sale within 2 years with agrivoltaic systems.
At the City Level, the relationship between rooftop PV development and demographic variables is analyzed. The relationship of solar PV installation with household income and unemployment rate remain consistent in cities of Phoenix and Tucson while it varies with other demographic parameters. Household income and owner occupancy shows very strong correlations with PV installation in most cities. A consistent spatial pattern of rooftop PV development based on demographic variables is difficult to discern.
Analysis of solar PV development at three different planning levels would help in proposing future policies for both large scale and rooftop solar PV in the state of Arizona.
The good news is that more and more communities see these plants for what they are: a wrong turn back to the dark days of dirty energy degrading community health, driving climate change and polluting the air, water, and soil we all share. With our planet’s future and the health of their families all on the line, everyday activists in communities throughout the Ohio River Basin are now banding together to fight back. You can too.
In order to determine what characteristics influence participation in this program I gathered data from multiple sources. I use a panel dataset of household water consumption that spans 12 years of approximately 300,000 homes. I merged this dataset with home structural characteristics, geographical, and demographic context. I then use these characteristics in a linear probability model, with school enrollment zone fixed effects to determine their influence on a household’s probability of participation. School zones are used to control for unobserved characteristics, such as demographics, which are not at a household level. I then utilize these school zone fixed effects in a 2nd stage regression to decompose these elements and analyze their effect on participation.
I find that a household’s water costs, as reflected in the marginal price faced in the summer and the differential between summer and winter water bills, as well as yard size are primary factors that influence participation. I also show that changes in rebate value and water rates can affect different types of households. There is also evidence to support that neighborhood characteristics affect a household’s likelihood of participating.
The photographs focused on aspects of life and behaviors that have contributed to happiness in local communities. A website was created and a gallery event was mounted for public review and discussion. Gallery attendees and website visitors were asked to complete a survey to assess (1) gained knowledge of sustainability solutions, and (2) how effective a tool photography is as a means of sustainability solutions communication.
This visual medium allowed people think about how to incorporate sustainable community solutions into their own lives and may have changed people’s interest in, and thoughts about, overall sustainability and sustainable solutions. The survey results demonstrated that photographs can successfully communicate sustainability ideas. Specifically, viewers gained an increased awareness of how community and urban gardening can increase happiness, well-being, and sense of community. This visual approach can continue to be used to more successfully communicate additional sustainability solutions ideas and methods to the public.
This report describes the process by which I created a concise but comprehensive online source of information about best practices in sustainability for urban planners. The goal of the project was to provide accessible information that would help planners in ways that help them comprehend and implement sustainable solutions to common planning problems that are found throughout the United States. To create the website, I researched methods for communicating clearly to planners, took a graduate course in communicating about sustainability, and drew on information that I had compiled on sustainable solutions for transportation, economy, water, green space, and governance.
