This paper explores the relationship between wildfire management and the consideration of ecological and environmental concerns in Arizona. To get a proper perspective on the current state of wildfire management in Arizona, information on two wildfire management programs, the Four Forests Restoration Initiative and FireScape, was researched and analyzed, as well as contemporary fire policy, a history of wildfire in Arizona, and two recent fires in Sedona, AZ. The two fires in Sedona, the Brins Fire of 2006 and the Slide Fire of 2014, act as a focal point for this ecological management transition, as even within an 8-year period, we can see the different ways the two fires were managed and the transition to a greater ecological importance in management strategies. These all came together to give a full spectrum for the factors that have led to more ecologically-prominent wildfire management strategies in Arizona.

As Arizona enters its fifteenth year of drought and Lake Mead hits historic lows, water management and policy planning will become increasingly important to ensure future water security in the Southwestern region of the United States. This thesis compares water demand trends and policies at the municipal level in Phoenix and Tucson, Arizona over the time period from 1980-2010. By analyzing gallons per capita per day (GPCD) trends for each city in the context of population growth, drought, and major state and local policies over the twenty year period, reasons for declines in per capita water demand were explored. Despite differences in their available water sources and political cultures, both the City of Phoenix and the City of Tucson have successfully reduced their per capita water consumption levels between 1980 and 2010. However, this study suggests that each city's measured success at reducing GPCD has been more a result of external events (supply augmentation, drought, and differing development trends) rather than conservation and demand reduction regulations adopted under the auspices of the Groundwater Management Act.

Human migration is not a new phenomenon but present and future human-induced environmental changes pose new questions and challenges. In the coming years, both rapid and slow onset environmental changes will drive many people to migrate in search of improved security and livelihoods. Anthropogenic climate change in particular requires international institutions to determine how to best meet the needs of present and future migrants. I analyzed interviews with experts to identify institutional gaps for managing environmental migration and what potential, if any, the Warsaw International Mechanism for loss and damage associated with climate change impacts (WIM) might contribute to filling these gaps. Using these interviews and literature, I propose a framework to assess the capacity of existing institutions to address the breadth of migrant needs. Then, I identify gaps and challenges in order to illuminate strategies for future solutions.

Natural resources management is a pressing issue for Native American nations and communities. More than ever before, tribal officials sit at the decision-making tables with federal and state officials as well as non-governmental natural resource stakeholders. This, however, has not always been the case. This dissertation focuses on tribal activism to demonstrate how and why tribal sovereignty, self-determination, and treaty rights protection are tied closely to contemporary environmental issues and natural resources management. With the Klamath Tribes of southern Oregon as a case study, this dissertation analyzes how a tribal nation garnered a political position in which it could both indirectly influence and directly orchestrate natural resource management within and outside of its sovereign boundaries. The Klamath Tribes experienced the devastating termination policy in the 1950s. Termination stripped them of their federal status as an Indian tribe, the government services offered to recognized tribes, and their 1.2-million-acre reservation. Despite this horrific event, the Klamaths emerged by the 2000s as leading natural resource stakeholders in the Klamath River Watershed, a region ten times larger than their former reservation. The Klamaths used tools, such as their treaty and water rights, and employed careful political, legal, and social tactics. For example, they litigated, appropriated science, participated in democratic national environmental policy processes, and developed a lexicon. They also negotiated and established alliances with non-governmental stakeholders in order to refocus watershed management toward a holistic approach that promoted ecological restoration.

This study applies spatial theory and an ethnohistorical approach to show how traditional values drove the Klamaths’ contemporary activism. From their perspective, healing the land would heal the people. The Klamaths’ history illuminates the active roles that tribes have had in the institutionalization of the federal self-determination policy as federal agencies resisted recognizing tribes and working with them in government-to-government relationships. Through their efforts to weave their interests into natural resource management with state, federal, and non-governmental stakeholders, the Klamaths took part in a much larger historical trend, the increased pluralization of American society.

Since the late 1990s thousands of new Border Patrol agents, hundreds of miles of fencing, and additional immigration checkpoints have been added to the Mexico-U.S. border region. This unprecedented increase in boundary enforcement has strained existing relationships and created new separations between people and places in the borderlands. Southwestern Arizona has been impacted in especially dramatic ways, as the “hardening” of the international boundary has transformed conservation and indigenous spaces into theaters of drug interdiction and immigration control. This dissertation explores this transformation in southwestern Arizona, a region that was known by Spanish Colonial administrators as the Papaguería. With the community of Ajo at the center of the narrative, this dissertation explores the ways that industry and conservation have long shaped the social relations and the landscape of the region. The destruction of old borders, the creation of new borders, and the redefinition of space has been an ongoing process that continues to define some groups of people as insiders and other groups as outsiders. In the current era of border security echoes from earlier colonial encounters reverberate into the present, shaping landscapes and the lives of local residents in the contemporary Papaguería in significant ways.

Postwar suburban sprawl resulted in environmental consequences that engendered backlash from those concerned about the quality life in the places they lived, played, and worked. Few cities grew as rapidly as Phoenix and therefore the city offers an important case study to evaluate the success and limits of environmentalism in shaping urban growth in the postwar period.

Using three episodes looking at sanitation and public health, open space preservation, and urban transportation, I argue three factors played a critical role in determining the extent to which environmental values were incorporated into Phoenix's urban growth policy. First, the degree to which environmental values influenced urban policy depends on the degree to which they fit into the Southwestern suburban lifestyle. A desire for low-density development and quality of life amenities like outdoor recreation resulted in decisions to extend municipal sewers further into the desert, the creation of a mountain preserve system, and freeways as the primary mode of travel in the city. Second, federal policy and the availability of funds guided policies pursued by Phoenix officials to deal with the unintended environmental impacts of growth. For example, federal dollars provided one-third of the funds for the construction of a centralized sewage treatment plant, half the funds to save Camelback Mountain and ninety percent of the construction costs for the West Papago-Inner Loop. Lastly, policy alternatives needed broad and diverse public support, as the public played a critical role, through bond approvals and votes, as well as grassroots campaigning, in integrating environmental values into urban growth policy. Public advocacy campaigns played an important role in setting the policy agenda and framing the policy issues that shaped policy alternatives and the public's receptivity to those choices.

Urban policy decisions are part of a dynamic and ongoing process, where previous decisions result in new challenges that provide an opportunity for debate, and the incorporation of new social values into the decision-making process. While twenty-first century challenges require responses that reflect contemporary macroeconomic factors and social values, the postwar period demonstrates the need for inclusive, collaborative, and anticipatory decision-making.

This dissertation explores how the written word and natural and cultural landscapes entwine to create a place, the process by which Arizona's landscapes affected narratives written about the place and how those narratives created representations of Arizona over time. From before Arizona became a state in 1912 to the day its citizens celebrated one hundred years as a state in 2012, words have played a role in making it the place it is. The literature about Arizona and narratives drawn from its landscapes reveal writers' perceptions, what they believe is important and useful, what motivates or attracts them to the place. Those perceptions translated into words organized in various ways create an image of Arizona for readers. I explore written works taken at twenty-five year intervals--1912 and subsequent twenty-five year anniversaries--synthesizing narratives about Arizona and examining how those representations of the place changed (or did not change). To capture one hundred years of published material, I chose sources from several genres including official state publications, newspapers, novels, poetry, autobiography, journals, federal publications, and the Arizona Highways magazine. I chose sources that would have been available to the reading public, publications that demonstrated a wide readership. In examining the words about Arizona that have been readily available to the English-reading public, the importance of the power of the printed word becomes clear. Arizona became the place it is in the twenty-first century, in part, because people with power--in the federal and state governments, boosters, and business leaders--wrote about it in such a way as to influence growth and tourism sometimes at the expense of minority groups and the environment. Minority groups' narratives in their own words were absent from Arizona's written narrative landscape until the second half of the twentieth century when they began publishing their own stories. The narratives about Arizona changed over time, from literature dominated by boosting and promotion to a body of literature with many layers, many voices. Women, Native American, and Hispanic narratives, and environmentalists' and boosters' words created a more complex representation of Arizona in the twenty-first century, and more accurately reflected its cultural landscape, than the Arizona represented in earlier narratives.

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.

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.

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.
