Description
Mexico City has an ongoing air pollution issue that negatively affects its citizens and surroundings with current structural disconnections preventing the city from improving its overall air quality. Thematic methodological analysis reveals current obstacles and barriers, as well as variables contributing to this persistent problem. A historical background reveals current programs and policies implemented to improve Mexico’s City air quality. Mexico City’s current systems, infrastructure, and policies are inadequate and ineffective. There is a lack of appropriate regulation on other modes of transportation, and the current government system fails to identify how the class disparity in the city and lack of adequate education are contributing to this ongoing problem. Education and adequate public awareness can potentially aid the fight against air pollution in the Metropolitan City.

Description
The Santa Cruz River Basin shared by Northern Sonora and Southern Arizona is one example of transboundary water resources in the borderlands region that accurately portrays the complexities of binational management of common pool resources, such as water. Industrialization fueled by trade liberalization has resulted in migration to and urbanization along the border, which have created human rights issues with the lack of water and sanitation, groundwater overdraft of the shared aquifers, and contamination of these scarce resources. Effluent from wastewater treatment plants continues to play increasingly important roles in the region, the use of which has been a source of tension between the two countries. Contributing to these tensions are the strains on binational relations created by border militarization and SB 1070. A shift in water management strategies to increase pubic participation within decision-making, increase the flexibility of the water systems, and increase cross-border collaboration is needed to ensure human and ecological sustainability in the Santa Cruz River Basin. By incorporating direct communication and local capacity as per common pool resource theory, recognizing the connections and implications of management actions through socio-ecological systems understanding, and promoting the organic drivers of change through ecologies of agents, just and vigorous futures can be envisioned and advanced.

Description
Residents of the United States increasingly support organic and local food systems. New Social Movement theorists have described alternative agriculture as a social movement that transcends social class. Other scholars have critiqued alternative agriculture for catering to a middle-class, white public. Simultaneously, geographers have identified communities across the United States that struggle with reduced access to healthy fruits and vegetables. In some of these neighborhoods, known as “food deserts,” local groups are redefining an inequitable distribution of healthy food as a social injustice, and they have begun initiatives to practice “food justice.” The overarching research questions of this study are: 1) How do communities become food deserts? 2) How do food justice movements crystallize and communities practice food justice? 3) What are the social outcomes of food justice movements? Using an Ecology of Actors framework, this study analyzes the actors and operational scales of three food justice movements in Phoenix, Arizona. A narrative analysis of historical scholarly materials and other artifacts reveals that, for more than a century, some communities have tried to create minority-operated local food systems. However, they were thwarted by racist policies and market penetration of the conventional US food system. Interviews with residents, garden organizers and food justice advocates living and working in the city create a narrative of the present day struggle for food justice. Results of this work show that contemporary residents describe their foodscape as one of struggle, and carless residents rely upon social networks to access healthy food. Garden organizers and gardeners are creating networks of community gardens, market gardens, and informal farmers’ markets. They are actively transforming their communities’ landscapes with sophisticated garden ecology in an intense urban heat island. However, the movement’s continued success may be threatened. Many new Phoenix-based local food coalitions and national alternative agriculture social movements are now working to alter Phoenix’s foodscape. Composed of well-educated professionals, who have adopted a justice-based language around food, these organizations may unintentionally co-opt the local food justice movements.

Description
The modern food system unsustainably produces both a food surplus and record levels of hunger. Capitalist investment into agriculture disrupted natural cycles and social relations. Marx’s concept of the metabolic rift describes the way capitalist agriculture actively deteriorates the ecology (ecological rift) and disenfranchises people from food (social rift) are traced on the global scale. Then these rifts are deeply explored on the local scale of Maricopa County, Arizona to reveal the ways that even local food systems are enmeshed within the global capitalist agricultural food system. Phoenix, AZ, located in Maricopa County, has made commitments to become equitable and sustainable by 2050 in part to address issues facing the local food system. Efforts to achieve this goal (policies and studies) are analyzed using the frameworks of sustainable development (dominant “green”/ market based sustainability) and just sustainabilities (disruptive/ justice oriented sustainability). These frameworks help determine whether local efforts mend the ecological and social rifts created by capitalist agriculture, or actively deepen them. While a few studies may attempt “sustainable” solutions, they may in fact further entrench local agriculture in an unsustainable globalized food system. The efforts that are able to address both rifts, challenging the logic and structures of capitalist agriculture, are lacking in scale. In order for Phoenix to reach its sustainability goals by 2050, the ecological and social rifts must be addressed together. To do this, residents and policy makers must be able to determine between efforts that toy at the edges of capitalist agriculture and those with transformational potential, as they challenge the structures and logic of capitalism, ultimately mending the metabolic rift. While this is being done on a small scale, much more is needed to achieve a truly just and sustainable food system.

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
Environmental hazards and disaster researchers have demonstrated strong associations between sociodemographic indicators, such as age and socio-economic status (SES), and hazard exposures and health outcomes for individuals and in certain communities. At the same time, behavioral health and risk communications research has examined how individual psychology influences adaptive strategies and behaviors in the face of hazards. However, at present, we do not understand the explanatory mechanisms that explain relationships between larger scale social structure, individual psychology, and specific behaviors that may attenuate or amplify risk. Extreme heat presents growing risks in a rapidly warming and urbanizing world. This dissertation examines the social and behavioral mechanisms that may explain inequitable health outcomes from exposure to concurrent extreme heat and electrical power failure in Phoenix, AZ and extreme heat in Detroit, MI. Exploratory analysis of 163 surveys in Phoenix, AZ showed that age, gender, and respondent’s racialized group identity did not relate to thermal discomfort and self-reported heat illness, which were only predicted by SES (StdB = -0.52, p < 0.01). Of the explanatory mechanisms tested in the study, only relative air conditioning intensity and thermal discomfort explained self-reported heat illness. Thermal discomfort was tested as both a mechanism and outcome measure. Content analysis of 40 semi-structured interviews in Phoenix, AZ revealed that social vulnerability was associated with an increase in perceived hazard severity (StdB = 0.44, p < 0.01), a decrease in perceived adaptation efficacy (StdB = -0.38, p = 0.02), and an indirect increase (through adaptive efficacy) in maladaptive intentions (StdB = 0.18, p = 0.01). Structural equation modeling of 244 surveys in Phoenix, AZ and Detroit, MI revealed that relationships between previous heat illness experience, perceived heat risk, and adaptive intentions were significantly moderated by adaptive capacity: high adaptive capacity households were more likely to undertake adaptive behaviors, and those decisions were more heavily influenced by risk perceptions and previous experiences. However, high adaptive capacity households had lower risk perceptions and fewer heat illness experiences than low adaptive capacity households. A better understanding of the mechanisms that produce social vulnerability can facilitate more salient risk messaging and more targeted public health interventions. For example, public health risk messaging that provides information on the efficacy of specific adaptations may be more likely to motivate self-protective action, and ultimately protect populations.
