Description
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.

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
Recognition of algae as a “Fit for Purpose” biomass and its potential as an energy and bio-product resource remains relatively obscure. This is due to the absence of tailored and unified production information necessary to overcome several barriers for commercial viability and environmental sustainability. The purpose of this research was to provide experimentally verifiable estimates for direct energy and water demand for the algal cultivation stage which yields algal biomass for biofuels and other bio-products. Algal biomass productivity was evaluated using different cultivation methods in conjunction with assessment for potential reduction in energy and water consumption for production of fuel and feed. Direct water and energy demands are the major focal sustainability metrics in hot and arid climates and are influenced by environmental and operational variables connected with selected algal cultivation technologies. Evaporation is a key component of direct water demand for algal cultivation and directly related to variations in temperature and relative humidity. Temperature control strategies relative to design and operational variables were necessary to mitigate overheating of the outdoor algae culture in panel photobioreactors and sub-optimal cultivation temperature in open pond raceways. Mixing in cultivation systems was a major component in direct energy demand that was provided by aeration in panel bioreactors and paddlewheels in open pond raceways. Management of aeration time to meet required biological interactions provides opportunities for reduced direct energy demand in panel photobioreactors. However, the potential for reduction in direct energy demand in raceway ponds is limited to hydraulics and head loss. Algal cultivation systems were reviewed for potential integration into dairy facilities in order to determine direct energy demand and nutrient requirements for algal biomass production for animal feed. The direct energy assessment was also evaluated for key components of related energy and design parameters for conventional raceway ponds and a gravity fed system. The results of this research provide a platform for selecting appropriate production scenarios with respect to resource use and to ensure a cost effective product with the least environmental burden.

Description
Fossil fuel CO2 (FFCO2) emissions are recognized as the dominant greenhouse gas driving climate change (Enting et. al., 1995; Conway et al., 1994; Francey et al., 1995; Bousquet et. al., 1999). Transportation is a major component of FFCO2 emissions, especially in urban areas. An improved understanding of on-road FFCO2 emission at high spatial resolution is essential to both carbon science and mitigation policy. Though considerable research has been accomplished within a few high-income portions of the planet such as the United States and Western Europe, little work has attempted to comprehensively quantify high-resolution on-road FFCO2 emissions globally. Key questions for such a global quantification are: (1) What are the driving factors for on-road FFCO2 emissions? (2) How robust are the relationships? and (3) How do on-road FFCO2 emissions vary with urban form at fine spatial scales?
This study used urban form/socio-economic data combined with self-reported on-road FFCO2 emissions for a sample of global cities to estimate relationships within a multivariate regression framework based on an adjusted STIRPAT model. The on-road high-resolution (whole-city) regression FFCO2 model robustness was evaluated by introducing artificial error, conducting cross-validation, and assessing relationship sensitivity under various model specifications. Results indicated that fuel economy, vehicle ownership, road density and population density were statistically significant factors that correlate with on-road FFCO2 emissions. Of these four variables, fuel economy and vehicle ownership had the most robust relationships.
A second regression model was constructed to examine the relationship between global on-road FFCO2 emissions and urban form factors (described by population
ii
density, road density, and distance to activity centers) at sub-city spatial scales (1 km2). Results showed that: 1) Road density is the most significant (p<2.66e-037) predictor of on-road FFCO2 emissions at the 1 km2 spatial scale; 2) The correlation between population density and on-road FFCO2 emissions for interstates/freeways varies little by city type. For arterials, on-road FFCO2 emissions show a stronger relationship to population density in clustered cities (slope = 0.24) than dispersed cities (slope = 0.13). FFCO2 3) The distance to activity centers has a significant positive relationship with on-road FFCO2 emission for the interstate and freeway toad types, but an insignificant relationship with the arterial road type.

Description
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.

Description
The Wasatch Front is an environmentally complex region, this area of northern Utah is mountainous and fertile enough to support a varied ecology. It has also supported healthy human populations. The marshy lands surrounding the gigantic lake antecedent to Great Salt Lake and Utah Lake provided food and resources for early peoples. Then, as the climate warmed and drought set in, the early Fremont culture was apparently unable to adapt. Now, the Wasatch Front is home to the majority of Utah’s population, putting this sensitive environment under considerable strain. When early Mormon settlers arrived to colonize the area in the mid nineteenth century, they set to work making the Wasatch Front into their idea of paradise. They borrowed language from the Hebrew Bible to describe the changes they had made, claiming they had made the desert “blossom as the rose.” The purpose of this dissertation is to examine the origins and manifestations of this complex ethos of “blossoming,” how Mormon culture has conceived and reconceived it, and how climatic realities have shaped and are shaping it. On one hand, “blossoming” entails a form of stewardship that encourages conservation and temperance. On the other hand, Mormons have continually sought to incorporate American ideals of abundance and mastery over the natural elements. Today, population pressure combined with the prospect of megadrought makes these tensions even more salient and threatens to recapitulate the maladaptations of earlier cultures in a pattern of withering rather than blossoming. This dissertation illustrates how the ill consequences of “blossoming” have repeatedly forced a pattern of return to the ethos of stewardship and might do so again.
