This dissertation explores vulnerability to extreme heat hazards in the Maricopa County, Arizona metropolitan region. By engaging an interdisciplinary approach, I uncover the epidemiological, historical-geographical, and mitigation dimensions of human vulnerability to extreme heat in a rapidly urbanizing region characterized by an intense urban heat island and summertime heat waves. I first frame the overall research within global climate change and hazards vulnerability research literature, and then present three case studies. I conclude with a synthesis of the findings and lessons learned from my interdisciplinary approach using an urban political ecology framework. In the first case study I construct and map a predictive index of sensitivity to heat health risks for neighborhoods, compare predicted neighborhood sensitivity to heat-related hospitalization rates, and estimate relative risk of hospitalizations for neighborhoods. In the second case study, I unpack the history and geography of land use/land cover change, urban development and marginalization of minorities that created the metropolitan region's urban heat island and consequently, the present conditions of extreme heat exposure and vulnerability in the urban core. The third study uses computational microclimate modeling to evaluate the potential of a vegetation-based intervention for mitigating extreme heat in an urban core neighborhood. Several findings relevant to extreme heat vulnerability emerge from the case studies. First, two main socio-demographic groups are found to be at higher risk for heat illness: low-income minorities in sparsely-vegetated neighborhoods in the urban core, and the elderly and socially-isolated in the expansive suburban fringe of Maricopa County. The second case study reveals that current conditions of heat exposure in the region's urban heat island are the legacy of historical marginalization of minorities and large-scale land-use/land cover transformations of natural desert land covers into heat-retaining urban surfaces of the built environment. Third, summertime air temperature reductions in the range 0.9-1.9 °C and of up to 8.4 °C in surface temperatures in the urban core can be achieved through desert-adapted canopied vegetation, suggesting that, at the microscale, the urban heat island can be mitigated by creating vegetated park cool islands. A synthesis of the three case studies using the urban political ecology framework argues that climate changed-induced heat hazards in cities must be problematized within the socio-ecological transformations that produce and reproduce urban landscapes of risk. The interdisciplinary approach to heat hazards in this dissertation advances understanding of the social and ecological drivers of extreme heat by drawing on multiple theories and methods from sociology, urban and Marxist geography, microclimatology, spatial epidemiology, environmental history, political economy and urban political ecology.

This study explores the potential risks associated with the 65 U.S.-based commercial nuclear power plants (NPPs) and the distribution of those risks among the populations of both their respective host communities and of the communities located in outlying areas. First, I examine the relevant environmental justice issues. I start by examining the racial/ethnic composition of the host community populations, as well as the disparities in socio-economic status that exist, if any, between the host communities and communities located in outlying areas. Second, I estimate the statistical associations that exist, if any, between a population's distance from a NPP and several independent variables. I conduct multivariate ordinary least square (OLS) regression analyses and spatial autocorrelation regression (SAR) analyses at the national, regional and individual-NPP levels. Third, I construct a NPP potential risk index (NPP PRI) that defines four discrete risk categories--namely, very high risk, high risk, moderate risk, and low risk. The NPP PRI allows me then to estimate the demographic characteristics of the populations exposed to each so-defined level of risk. Fourth, using the Palo Verde NPP as the subject, I simulate a scenario in which a NPP experiences a core-damage accident. I use the RASCAL 4.3 software to simulate the path of dispersion of the resultant radioactive plume, and to investigate the statistical associations that exist, if any, between the dispersed radioactive plume and the demographic characteristics of the populations located within the plume's footprint. This study utilizes distributive justice theories to understand the distribution of the potential risks associated with NPPs, many of which are unpredictable, irreversible and inescapable. I employ an approach that takes into account multiple stakeholders in order to provide avenues for all parties to express concerns, and to ensure the relevance and actionability of any resulting policy recommendations.

Low-income communities of color in the U.S. today are often vulnerable to displacement, forced relocation away from the places they call home. Displacement takes many forms, including immigration enforcement, mass incarceration, gentrification, and unwanted development. This dissertation juxtaposes two different examples of displacement, emphasizing similarities in lived experiences. Mixed methods including document-based research, map-making, visual ethnography, participant observation, and interviews were used to examine two case studies in Phoenix, Arizona: (1) workplace immigration raids, which overwhelmingly target Latino migrant workers; and (2) the Loop 202 freeway, which would disproportionately impact Akimel O'odham land. Drawing on critical geography, critical ethnic studies, feminist theory, carceral studies, and decolonial theory, this research considers: the social, economic, and political causes of displacement, its impact on the cultural and social meanings of space, the everyday practices that allow people to survive economically and emotionally, and the strategies used to organize against relocation.

Although raids are often represented as momentary spectacles of danger and containment, from a worker's perspective, raids are long trajectories through multiple sites of domination. Raids' racial geographies reinforce urban segregation, while traumatization in carceral space reduces the power of Latino migrants in the workplace. Expressions of care among raided workers and others in jail and detention make carceral spaces more livable, and contribute to movement building and abolitionist sentiments outside detention.

The Loop 202 would result in a loss of native land and sovereignty, including clean air and a mountain sacred to O'odham people. While the proposal originated with corporate desire for a transnational trade corridor, it has been sustained by local industry, the perceived inevitability of development, and colonial narratives about native people and land. O'odham artists, mothers, and elders counter the freeway's colonial logics through stories that emphasize balance, collective care over individual profit, and historical consciousness.

Both raids and the freeway have been contested by local grassroots movements. Through political education, base-building, advocacy, lawsuits, and protest strategies, community organizations have achieved changes in state practice. These movements have also worked to create alternative spaces of safety and home, rooted in interpersonal care and Latino and O'odham culture.

In this study, the researcher develops a documentary-driven methodology to understand the ways four women in the United States use their involvement in the belly dance phenomenon to shape their ongoing individual identity development. The filmmaking process itself and its efficacy as a process to promote self-understanding and identity growth among the participating belly dancers, are also investigated phenomenologically. Methodological steps taken in the documentary-driven methodology include: initial filmed interviews, co-produced filmed dance performances, editorial interviews to review footage with each dancer, documentary film production, dancer-led focus groups to screen the film, and exit interviews with each dancer. The project generates new understandings about the ways women use belly dance to shape their individual identities to include: finding community with other women in private women's spaces, embodying the music through the dance movements, and finding liberation from their everyday "selves" through costume and performance.

Following harsh economic and political reforms in the 1990s, Peru became a model of a neoliberal state based on natural resource extraction. Since then social and environmental conflicts between local communities and the extractive industry, particularly mining corporations, have multiplied resulting in violent clashes and a shared perception that the state is not guaranteeing people's rights. At the crossroads of the struggle between mining corporations and local communities lay different ways of living and relating to nature. This research concerns water conflict in an urban mining setting. More precisely, this research critically analyzes water conflict in the city of Arequipa as a backdrop for revealing what water injustices look like on the ground. With one million inhabitants, Arequipa is the second largest city in Peru. Arequipa is also home to the third largest copper mine in Peru. On June 2006, social organizations and political authorities marched in protest of the copper mine's acquisition of additional water rights and its use of a tax exemption program. In the aftermath of large protests, the conflict was resolved through a multi-actor negotiation in which the mine became, through a public-private partnership, co-provider of urban water services. Through a unique interdisciplinary theoretical approach and grounded on ethnographic methods I attempt to expose the complexity of water injustice in this particular case. My theoretical framework is based on three large fields of study, that of post-colonial studies, political ecology and critical studies of law. By mapping state-society-nature power relations, analyzing structures of oppression and unpacking the meaning of water rights, my research unveils serious water injustices. My first research finding points to the existence of a racist and classist system that excludes poor and marginal people from water services and from accessing the city. Second, although there are different social and cultural interpretations of water rights, some interpretations hold more power and become hegemonic. Water injustice, in this regard manifests by the rise in power of the economic view of water rights. Finally, neoliberal reforms prioritizing development based on the extractive industries and the commodification of nature are conducive to water injustices.

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.

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.

Increasingly, wildfires are threatening communities, forcing evacuations, damaging property, and causing loss of life. This is in part due to a century of wildfire policy and an influx of people moving to the wildland urban interface (WUI). National programs have identified and promoted effective wildfire mitigation actions to reduce wildfire risk; yet, many homeowners do not perform these actions. Based on previous literature and using the theory of planned behavior (TPB), this study proposes an integrated wildfire mitigation behavioral model to assess and identify the factors that influence homeowners’ wildfire mitigation behaviors. Specifically, the study tests the validity of the theory of planned behavior as a foundational model in exploring wildfire mitigation behaviors, develops and empirically tests a wildfire mitigation behavioral model, and explores the role of homeowner associations (HOA) on wildfire mitigation behaviors. Structural equation modeling was used on data collected from homeowners with property in the WUI in Prescott, Arizona. Results suggest TPB provides an acceptable model in describing homeowner wildfire mitigation behavior. For HOA residents, attitudes toward wildfire mitigation behaviors play an important role in predicting intentions to perform these behaviors. Additionally, perceived constraints directly influenced actual mitigation actions. For non-HOA residents, subjective norms influenced intentions to mitigate. Implications for research and local wildfire mitigation programs and policy are discussed.

Crowding and satisfaction remain widely studied concepts among those seeking to understand quality visitor experiences. One area of interest in this study is how the order of crowding and satisfaction items on a survey affects their measurement levels. An additional area of interest is the influence of personality traits on experience-use-history, crowding, and satisfaction. This study used two versions of a survey: A) crowding measured prior to satisfaction and B) satisfaction measured prior to crowding, to explore the influence of item order on crowding and satisfaction levels. Additionally, the study explored the influence of personality traits (extraversion and neuroticism) and experience use history (EUH) on crowding and satisfaction. EUH was included as a variable of interest given previous empirical evidence of its influence on crowding and satisfaction. Data were obtained from an onsite self-administered questionnaire distributed to day use visitors at a 16,000 acre desert landscape municipal park in Arizona. A total of 619 completed questionnaires (equally distributed between the two survey versions) were obtained. The resulting response rate was 80%. One-way ANOVA's indicated significant differences in crowding and satisfaction levels with both crowding and satisfaction levels being higher for survey version B. Path analysis was used to test the influence of personality traits and EUH on crowding and satisfaction. Two models, one for each version of the survey were developed using AMOS 5. The first model was tested using data in which crowding was measured prior to satisfaction. The second model relied on data in which satisfaction was measured prior to crowding. Results indicated that personality traits influenced crowding and satisfaction. Specifically, in the first model, significant relationships were observed between neuroticism and crowding, neuroticism and EUH, EUH and crowding, and between crowding and satisfaction. In the second model, significant relationships were observed between extraversion and crowding, extraversion and satisfaction, and between EUH and satisfaction. Findings suggest crowding and satisfaction item order have a potential to influence their measurement. Additionally, results indicate that personality traits potentially influence visitor experience evaluation. Implications of these findings are discussed.

Program leadership’s decision to include an evaluator during the program planning and design phase is the critical first step necessary for evaluators to provide the programmatic benefits associated with the evaluation profession. Several recent developments have promoted evaluator inclusion in program planning and design activities, including federal legislation that mandates evaluator inclusion and advocacy efforts from evaluation academics. However, the evaluation literature presents a collective frustration within the evaluation field due to ongoing exclusion from program planning and design activities. Utilizing the defensive attribution hypothesis, this quantitative study gathered responses from 260 American Evaluation Association members and 61 Project Management Institute members to determine an evaluator exclusion rate, develop a taxonomy of exclusion factors, and explore the extent to which program leaders and program evaluators demonstrate defensive attributions when rating these factors’ influence on evaluator exclusion in program planning and design activities. Results indicated an approximately 70% evaluator exclusion rate in respondents’ most recent program experiences. Furthermore, the defensive attribution hypothesis was not supported in the study, as program evaluators more strongly attributed their lack of inclusion to deficiencies outside of the evaluation practice, but program leaders also more strongly attributed evaluator exclusion to deficiencies outside of the evaluation practice. Program evaluators most strongly attributed their exclusion to program leaders’ insufficient training and knowledge on the role of evaluation during the program planning and design phase. Program leaders most strongly attributed evaluator exclusion to their own staffing decisions, indicating a preference to not include evaluators in program planning and design activities due to achieving previous program success without them, assigning evaluation activities to non-evaluation staff, and a funding process that allows the practice to occur. As the first study to explore evaluator exclusion in the program planning and design phase, it sets a foundation for future research studies to corroborate and build upon its findings, identify policies that encourage evaluator inclusion, and continue efforts to establish mutually beneficial relationships in the program planning and design phase.
