Description
Growers and the USDA showed increasing favor for agricultural chemicals over cultural and biological forms of pest control through the first half of the twentieth century. With the introduction of DDT and other synthetic chemicals to commercial markets in the post-World War II era, pesticides became entrenched as the primary form of pest control in the industrial agriculture production system. Despite accumulating evidence that some pesticides posed a threat to human and environmental health, growers and government exercised path-dependent behavior in the development and implementation of pest control strategies. As pests developed resistance to regimens of agricultural chemicals, growers applied pesticides with greater toxicity in higher volumes to their fields with little consideration for the unintended consequences of using the economic poisons. Consequently, pressure from non-governmental organizations proved a necessary predicate for pesticide reform. This dissertation uses a series of case studies to examine the role of non-governmental organizations, particularly environmental organizations and farmworker groups, in pesticide reform from 1962 to 2011. For nearly fifty years, these groups served as educators, communicating scientific and experiential information about the adverse effects of pesticides on human health and environment to the public, and built support for the amendment of pesticide policies and the alteration of pesticide use practices. Their efforts led to the passage of more stringent regulations to better protect farmworkers, the public, and the environment. Environmental organizations and farmworker groups also acted as watchdogs, monitoring the activity of regulatory agencies and bringing suit when necessary to ensure that they fulfilled their responsibilities to the public. This dissertation will build on previous scholarly work to show increasing collaboration between farmworker groups and environmental organizations. It argues that the organizations shared a common concern about the effects of pesticides on human health, which enabled bridge-builders within the disparate organizations to foster cooperative relationships. Bridge-building proved a mutually beneficial exercise. Variance in organizational strategies and the timing of different reform efforts limited, but did not eliminate, opportunities for collaboration. Coalitions formed when groups came together temporarily, and then drifted apart when a reform effort reached its terminus, leaving future collaboration still possible.

Description
The rights of American Indians occupy a unique position within the legal framework of water allocations in the western United States. However, in the formulation and execution of policies that controlled access to water in the desert Southwest, federal and local governments did not preserve the federal reserved water rights that attached to Indian reservations as part of their creation. Consequentially, Indian communities were unable to access the water supplies necessary to sustain the economic development of their reservations. This dissertation analyzes the legal and historical dimensions of the conflict over rights that occurred between Indian communities and non-Indian water users in Arizona during the second half of the twentieth century. Particular attention is paid to negotiations involving local, state, federal, and tribal parties, which led to the Congressional authorization of water rights settlements for several reservations in central Arizona. The historical, economic, and political forces that shaped the settlement process are analyzed in order to gain a better understanding of how water users managed uncertainty regarding their long-term water supplies. The Indian water rights settlement process was made possible through a reconfiguration of major institutional, legal, and policy arrangements that dictate the allocation of water supplies in Arizona.

Description
The act of moving water across basins is a recent phenomenon in Arizona water policy. This thesis creates a narrative arc for understanding the long-term issues that set precedents for interbasin water transportation and the immediate causes--namely the passage of the seminal Groundwater Management Act (GMA) in 1980--that motivated Scottsdale, Mesa, and Phoenix to acquire rural farmlands in the mid-1980s with the intent of transporting the underlying groundwater back to their respective service areas in the immediate future. Residents of rural areas were active participants in not only the sales of these farmlands, but also in how municipalities would economically develop these properties in the years to come. Their role made these municipal "water farm" purchases function as exchanges. Fears about the impact of these properties and the water transportation they anticipated on communities-of-origin; the limited nature of economic, fiscal, and hydrologic data at the time; and the rise of private water speculators turned water farms into a major political controversy. The six years it took the legislature to wrestle with the problem at the heart this issue--the value of water to rural communities--were among its most tumultuous. The loss of key lawmakers involved in GMA negotiations, the impeachment of Governor Evan Mecham, and a bribery scandal called AZScam collectively sidetracked negotiations. Even more critical was the absence of a mutual recognition that these water farms posed a problem and the external pressure that had forced all parties involved in earlier groundwater-related negotiations to craft compromise. After cities and speculators failed to force a bill favorable to their interests in 1989, a re-alignment among blocs occurred: cities joined with rural interests to craft legislation that grandfathered in existing urban water farms and limited future water farms to several basins. In exchange, rural interests supported a bill to create a Phoenix-area groundwater replenishment district that enabled cooperative management of water supplies. These two bills, which were jointly signed into law in June 1991, tentatively resolved the water farm issue. The creation of a groundwater replenishment district that has subsidized growth in Maricopa, Pinal, and Pima Counties, the creation water bank to store unused Central Arizona Project water for times of drought, and a host of water conservation measures and water leases enabled by the passage of several tribal water rights settlements have set favorable conditions such that Scottsdale, Mesa, and Phoenix never had any reason to transport any water from their water farms. The legacy of these properties then is that they were the product of the intense urgency and uncertainty in urban planning premised on assumptions of growing populations and complementary, inelastic demand. But even as per capita water consumption has declined throughout the Phoenix-area, continued growth has increased demand, beyond the capacity of available supplies so that there will likely be a new push for rural water farms in the foreseeable future.

Description
Extreme hot-weather events have become life-threatening natural phenomena in many cities around the world, and the health impacts of excessive heat are expected to increase with climate change (Huang et al. 2011; Knowlton et al. 2007; Meehl and Tebaldi 2004; Patz 2005). Heat waves will likely have the worst health impacts in urban areas, where large numbers of vulnerable people reside and where local-scale urban heat island effects (UHI) retard and reduce nighttime cooling. This dissertation presents three empirical case studies that were conducted to advance our understanding of human vulnerability to heat in coupled human-natural systems. Using vulnerability theory as a framework, I analyzed how various social and environmental components of a system interact to exacerbate or mitigate heat impacts on human health, with the goal of contributing to the conceptualization of human vulnerability to heat. The studies: 1) compared the relationship between temperature and health outcomes in Chicago and Phoenix; 2) compared a map derived from a theoretical generic index of vulnerability to heat with a map derived from actual heat-related hospitalizations in Phoenix; and 3) used geospatial information on health data at two areal units to identify the hot spots for two heat health outcomes in Phoenix. The results show a 10-degree Celsius difference in the threshold temperatures at which heat-stress calls in Phoenix and Chicago are likely to increase drastically, and that Chicago is likely to be more sensitive to climate change than Phoenix. I also found that heat-vulnerability indices are sensitive to scale, measurement, and context, and that cities will need to incorporate place-based factors to increase the usefulness of vulnerability indices and mapping to decision making. Finally, I found that identification of geographical hot-spot of heat-related illness depends on the type of data used, scale of measurement, and normalization procedures. I recommend using multiple datasets and different approaches to spatial analysis to overcome this limitation and help decision makers develop effective intervention strategies.

Description
The State of California has made great strides in reducing greenhouse gas (GHG) emissions through mandated, rate-payer funded Investor Owned Utility (IOU) electricity Demand Side Management (DSM) programs. This study quantifies the amount of reduced GHG emissions in Arizona that result from DSM in that state, as well as the DSM reductions within Southern California Edison (SCE), Pacific Gas and Electric (PG&E;), and San Diego Gas and Electric (SDG&E;) during the 2010 through 2012 California Public Utilities Commission (CPUC) DSM program cycle. To accomplish this quantification, it develops a model to allocated GHG emissions based on "operating margin" resources requirements specific to each utility in order to effectively track, monitor, and quantify avoided emissions from grid-based utility resources. The developed model estimates that during the 2010-2012 program cycle, 5,327.12 metric tons (MT) of carbon dioxide equivalents (CO2e) in GHG reductions (or 1.8 percent of total reductions) can be attributed to reduced demand from Arizona--based resources by California IOUs. By focusing on the spatial context of GHG emission reductions, this study models and quantifies the spill-over effect of California's regulatory environment into neighboring states.

Description
The lack of substantive, multi-dimensional perspectives on civic space planning and design has undermined the potential role of these valuable social and ecological amenities in advancing urban sustainability goals. Responding to these deficiencies, this dissertation utilized mixed quantitative and qualitative methods and synthesized multiple social and natural science perspectives to inform the development of progressive civic space planning and design, theory, and public policy aimed at improving the social, economic, and environmental health of cities. Using Phoenix, Arizona as a case study, the analysis was tailored to arid cities, yet the products and findings are flexible enough to be geographically customized to the social, environmental, built, and public policy goals of other urbanized regions. Organized into three articles, the first paper applies geospatial and statistical methods to analyze and classify urban parks in Phoenix based on multiple social, ecological, and built criteria, including landuse-land cover, `greenness,' and site amenities, as well as the socio- economic and built characteristics of park neighborhoods. The second article uses spatial empirical analysis to rezone the City of Phoenix following transect form-based code. The current park system was then assessed within this framework and recommendations are presented to inform the planning and design of civic spaces sensitive to their social and built context. The final paper culminates in the development of a planning tool and site design guidelines for civic space planning and design across the urban-to-natural gradient augmented with multiple ecosystem service considerations and tailored to desert cities.

Description
Despite the arid climate of Maricopa County, Arizona, vector-borne diseases have presented significant health challenges to the residents and public health professionals of Maricopa County in the past, and will continue to do so in the foreseeable future. Currently, West Nile virus is the only mosquitoes-transmitted disease actively, and natively, transmitted throughout the state of Arizona. In an effort to gain a more complete understanding of the transmission dynamics of West Nile virus this thesis examines human, vector, and environment interactions as they exist within Maricopa County. Through ethnographic and geographic information systems research methods this thesis identifies 1) the individual factors that influence residents' knowledge and behaviors regarding mosquitoes, 2) the individual and regional factors that influence residents' knowledge of mosquito ecology and the spatial distribution of local mosquito populations, and 3) the environmental, demographic, and socioeconomic factors that influence mosquito abundance within Maricopa County. By identifying the factors that influence human-vector and vector-environment interactions, the results of this thesis may influence current and future educational and mosquito control efforts throughout Maricopa County.

Description
Cordon pricing strategies attempt to charge motorists for the marginal social costs of driving in heavily congested areas, lure them out of their vehicles and into other modes, and thereby reduce vehicle miles traveled and congestion-related externalities. These strategies are gaining policy-makers` attention worldwide. The benefits and costs of such strategies can potentially lead to a disproportionate and inequitable burden on lower income commuters, particularly those commuters with poor accessibility to alternative modes of transportation. Strategies designed to mitigate the impacts of cordon pricing for disadvantaged travelers, such as discount and exemptions, can reduce the effectiveness of the pricing strategy. Transit improvements using pricing fee revenues are another mitigation strategy, but can be wasteful and inefficient if not properly targeted toward those most disadvantaged and in need. This research examines these considerations and explores the implications for transportation planners working to balance goals of system effectiveness, efficiency, and equity. First, a theoretical conceptual model for analyzing the justice implications of cordon pricing is presented. Next, the Mobility Access and Pricing Study, a cordon pricing strategy examined by the San Francisco County Transportation Authority is analyzed utilizing a neighborhood-level accessibility-based approach. The fee-payment impacts for low-income transportation-disadvantaged commuters within the San Francisco Bay area are examined, utilizing Geographic Information Systems coupled with data from the Longitudinal Employment and Household Dynamics program of the US Census Bureau. This research questions whether the recommended blanket 50% discount for low-income travelers would unnecessarily reduce the overall efficiency and effectiveness of the cordon pricing system. It is proposed that reinvestment of revenue in transportation-improvement projects targeted at those most disproportionately impacted by tolling fees, low-income automobile-dependent peak-period commuters in areas with poor access to alternative modes, would be a more suitable mitigation strategy. This would not only help maintain the efficiency and effectiveness of the cordon pricing system, but would better address income, modal and spatial equity issues. The results of this study demonstrate how the spatial distribution of the toll-payment impacts may burden low-income residents in quite different ways, thereby warranting the inclusion of such analysis in transportation planning and practice.

Description
A sequence of models is developed to describe urban population growth in the context of the embedded physical, social and economic environments and an urban disease are developed. This set of models is focused on urban growth and the relationship between the desire to move and the utility derived from city life. This utility is measured in terms of the economic opportunities in the city, the level of human constructed amenity, and the level of amenity caused by the natural environment. The set of urban disease models is focused on examining prospects of eliminating a disease for which a vaccine does not exist. It is inspired by an outbreak of the vector-borne disease dengue fever in Peru, during 2000-2001.

Description
Education for sustainable development (ESD) is an academic goal for many courses in higher learning. ESD encompasses a specific range of learning outcomes, competencies, skills and literacies that include and exceed the acquisition of content knowledge. Methods and case studies for measuring learning outcomes in ESD is absent from the literature. This case study of an undergraduate course in urban sustainability examines the processes, curriculum, pedagogies, and methods to explore whether or not learning outcomes in education for sustainable development are being reached. Observations of the course, and the statistical analysis of student surveys from course evaluations, are explored to help identify the relationships between learning outcomes in ESD and the processes of learning and teaching in the case study. Recommendations are made for applying the lessons of the case study to other courses, and for continuing further research in this area.
