Description
The San Andreas Fault (SAF) is the primary structure within a system of faults accommodating motion between the North American and Pacific plates. Physical models of faulting and characterizations of seismic hazard are informed by investigations of paleoseismology, slip distribution, and slip rate. The impact of earthquakes on people is due in large part to social vulnerability. This dissertation contributes an analysis about the relationships between earthquake hazard and social vulnerability in Los Angeles, CA and investigations of paleoseismology and fault scarp array complexity on the central SAF. Analysis of fault scarp array geometry and morphology using 0.5 m digital elevation models along 122 km of the central SAF reveals significant variation in the complexity of SAF structure. Scarp trace complexity is measured by scarp separation, changes in strike, fault trace gaps, and scarp length per SAF kilometer. Geometrical complexity in fault scarp arrays indicates that the central SAF can be grouped into seven segments. Segment boundaries are controlled by interactions with subsidiary faults. Investigation of an offset channel at Parkfield, CA yields a late Holocene slip rate of 26.2 +6.4/- 4.3 mm/yr. This rate is lower than geologic measurements on the Carrizo section of the SAF and rates implied by far-field geodesy. However, it is consistent with historical observations of slip at Parkfield. Paleoseismology at Parkfield indicates that large earthquakes are absent from the stratigraphic record for at least a millennia. Together these observations imply that the amount of plate boundary slip accommodated by the main SAF varies along strike. Contrary to most environmental justice analyses showing that vulnerable populations are spatially-tied to environmental hazards, geospatial analyses relating social vulnerability and earthquake hazard in southern California show that these groups are not disproportionately exposed to the areas of greatest hazard. Instead, park and green space is linked to earthquake hazard through fault zone regulation. In Los Angeles, a parks poor city, the distribution of social vulnerability is strongly tied to a lack of park space. Thus, people with access to financial and political resources strive to live in neighborhoods with parks, even in the face of forewarned risk.

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
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
This dissertation examines the development of grassroots environmental organizations between 1970 and 2000 and the role they played in the larger American environmental movement and civil society during that period. Much has been written about growth in environmental values in the United States during the twentieth century and about the role of national environmental organizations in helping to pass landmark federal-level environmental laws during the 1960s and 1970s. This study illuminates a different story of how citizen activists worked to protect and improve the air, water, healthfulness and quality of life of where they lived. At the local level, activists looked much different than they did in Washington, D.C.--they tended to be volunteers without any formal training in environmental science or policy. They were also more likely to be women than at the national level. They tended to frame environmental issues and solutions in familiar ways that made sense to them. Rather than focusing on the science or economics of an environmental issue, they framed it in terms of fairness and justice and giving citizens a say in the decisions that affected their health and quality of life. And, as the regulatory, political, and social landscape changed around them, they adapted their strategies in their efforts to continue to affect environmental decision making. Over time, they often connected their local interests and issues with more sophisticated, globalized understandings of the economic and political systems that under laid environmental issues. This study examines three case studies in the rural Great Plains, urban Southwest, and small-town Appalachia between 1970 and 2000 in an attempt to understand community-based environmental activism in the late twentieth century, how it related to the national environmental movement, the strategies local-level groups employed and when and why, the role of liberal democratic arguments in their work and in group identity formation, the limits of those arguments, and how the groups, their strategies, and the activists themselves changed overtime. These three groups were the Northern Plains Resource Council in Montana, Southwest Environmental Service in Southern Arizona, and Save Our Cumberland Mountains in Eastern Tennessee.

Description
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.

Description
There is a growing consensus that environmental hazards and changing weather patterns disproportionately affect the poor, vulnerable, minority communities. My dissertation studies the nature of risk faced by vulnerable groups of individuals, how these risks affect their labor choice, income, consumption, and migration patterns. In Chapter 1, I study how seniors of different racial and income groups respond to information about hazardous waste sites in their neighborhood and their cleanup process. I find white seniors tend to move out at a higher rate when informed about the presence of a waste site as well as when the site is cleaned up compared to non-white seniors. This suggests that neighborhood gentrification exhibits inertia in the manifestation after the cleanup of Superfund sites. I find an assortative matching of seniors to neighborhoods based on their race and income, reinforcing findings in the environmental justice literature. Chapter 2 documents the effect of drought on labor choices, income, and consumption of rural households in India. I find that household consumption, as well as agricultural jobs, declines in response to drought. Further, I find that these effects are mediated by job skills and land ownership. Specifically, I find that households with working members who have completed primary education account for most of the workers who exit the agricultural sector. In contrast, I find that households with farmland increase their agricultural labor share post-drought. Cultural norms, relative prices, and land market transaction costs provide potential explanations for this behavior. Chapter 3 builds a simple model of household labor allocation based on reduced-form evidence I find in chapter 2. Simulation of the calibrated model implies that projected increases in the frequency of droughts over the next 30 years will have a net effect of a 1\% to 2\% reduction in agricultural labor. While small in percentage terms, this implies that 2.5 to 5 million individuals would leave agriculture. An increase in drought will also increase the size of the manufacturing wage subsidy needed to meet the goals of `Make in India’ policy by 20\%. This is driven by the need to incentivize landowners to reduce farm labor.

Description
This research explores Western society’s inability to address climate change substantively and the pathology of modernity. This dissertation resulted in two deliverables: (1) a persuasive critical literature review that defined and framed the pathology of modernity, and (2) an autoethnography on the pathology of modernity. Paper one showed the connections linking climate change and colonization by drawing on political ecology, Indigenous studies, environmental justice, sociology, postcolonial studies, and decolonial studies. After building a case for Western society’s responsibility for climate change, depth psychology was used to examine why many of contemporary society’s Western leaders tend to deny or ignore climate change and related systemic issues. This mindset is proposed to be an expression of a societal illness I define as the pathology of modernity. In paper two, the pathology of modernity is described through an autoethnography of my community organizing. This research used both a decolonial methodology as well as was inspired by grounded theory. Methods for the deliverables included a critical argumentative literature review and autoethnography. This research intends to change the conversation around climate change, addressing the structural power-based issues and mentality in Western society that prevents climate justice and climate action.

Description
The governance of natural resources often gets implicitly or explicitly shaped by the knowledge systems that are invoked for making decisions. These knowledge systems reflect the underlying notions of how human-nature relationships are conceived and operationalized by different stakeholders in the governance system. Conflicts in the science-policy interface in environmental governance arise when specific conceptions of nature dominate over other ways of knowing, when stakeholders with representing different knowledge systems have disproportionate degrees of influence in policymaking spaces, or when certain stakeholders are deracinated from their resources and long-held knowledge traditions. This dissertation examines the epistemic conflicts that exist in the Indian forestry that have led to a situation of policy stalemate in the governance system and continue to perpetuate colonial systems of scientific forestry and marginalize local knowledge traditions. To do so, this dissertation analyzes three datasets to understand the extent and consequences of this conflict in the forestry sciences in Indian academia. First, scientific discourses on the Indian Forest Rights Act are examined to understand the normative and epistemic practices that lead to differences in perspectives and scientific positions on forest governance. Second, the forest policy literature is analyzed using bibliometrics techniques to identify the intellectual and social silos in forestry sciences in India. Third, interview data from Indian forest scientists is analyzed to understand the inequalities within the science-policy interface in Indian forestry and how these perpetuate colonial legacies of forestry science. This dissertation concludes with recommendations and future pathways for knowledge integration and policy deliberations to make more decolonial, inclusive, and sustainable policies in Indian forestry.

Description
Widespread human rights abuses have been documented in global fisheries, prompting governments, intergovernmental organizations, non-governmental organizations, and businesses to reconsider human rights as a key tenet of seafood sustainability. New and existing approaches are aiming to integrate human and labor rights into sustainability initiatives. These efforts encompass the development of new tools for conducting human rights due diligence and the modification of market-based approaches like third-party certifications, fishery improvement projects, and buyer sourcing commitments to include criteria for social responsibility. It is critical to evaluate these approaches to better understand their efficacy and areas in need of improvement. This dissertation explores how approaches for seafood sustainability are being adapted to protect and respect human rights of fishers and fishworkers. First, I examine the efficacy of a recognized human rights risk assessment tool: the Social Responsibility Assessment Tool for the Seafood Sector (SRA). Through a preliminary assessment of human rights risk in Guyana’s artisanal fishery, I determined that the SRA is an effective approach to identify visible and potential risk, though it must be supplemented with engagement with fishers and fishworkers through interviews. Next, I evaluated labor conditions in the shrimp and groundfish fishery of the Guianas-Brazil Shelf using a novel evaluative framework for decent work. I uncovered cross-jurisdictional challenges including trafficking and limited worker representation. My evaluative framework enabled a holistic analysis of decent work, identifying linked concerns such as widespread illegal fishing and threats to food security. Finally, I conducted an analysis of market-based approaches that include criteria for social responsibility. Interviews with experts highlight that market-based approaches, particularly fishery improvement projects, hold great potential as strategies to improve human rights in fisheries. However, concerns around market-based approaches include a lack of strong enforcement mechanisms, limited worker representation, and the voluntary nature of initiatives hinder effective change on the ground. Overall, my research suggests that efforts to improve human rights in fisheries are nascent and need further development. By encouraging mandatory due diligence, improved worker representation, and stricter accountability, interventions can more effectively address risks and ensure rights of fishers and fishworkers are protected and respected.

Description
Concerns about the environmental and social impacts of anthropogenic climate change have called into question the efficacy, efficiency, and equity of energy systems. People committed to renewable energy transitions, and those who defend fossil-based systems, are simultaneously envisioning energy futures and seeking to build them. In the process, they are changing both energy technologies and how social life is organized around them. In this dissertation, I examine how ideas and materialities around distributed solar power become inscribed into energy policies, etched into urban landscapes, and embedded into city life. These processes engender particular kinds of embodied communities, which I define as solar communities. I study the visual and affective dimensions of emerging solar communities in Arizona and Italy using the qualitative methods of semi-structured interviews, photo-documentation, and observation. The dissertation consists of three papers. In Chapter 2, I explore how rooftops are constructed as newly productive sites for electricity generation through economic, legal, cartographic, and political negotiations, and how they become sites of struggle over who has access to them. I describe a case study in Phoenix about a proposed change in compensation for residential rooftop solar customers and the affective dynamics of a protest around it. In Chapter 3, I examine how a variety of photovoltaic applications are appearing in urban landscapes in Treviso, Italy and Flagstaff, Arizona. I investigate how aesthetic and environmental values are imbued in the physical forms those installations ultimately take, and the role that in/visibility plays in shaping these decisions. I use photography to document these emergent solar communities and argue that there is value to seeing photovoltaics in your city. In Chapter 4, I describe a workshop I led on the human dimensions and ethical trade-offs of renewable energy transitions using interactive activities and case studies from Ethiopia and Appalachia. I show how decisions about energy transitions have far-reaching impacts on people’s lives, health, the way they work, and geopolitical relationships. Together, these chapters begin to form a picture of the governance around, and visuality of, photovoltaic designs that emerge as fixtures of both landscape and society, which in turn inform solar communities.
