Description
With the ongoing drought surpassing a decade in Arizona, scholars, water managers and decision-makers have heightened attention to the availability of water resources, especially in rapidly growing regions where demand may outgrow supplies or outpace the capacity of the community water systems. Community water system managing entities and the biophysical and social characteristics of a place mediate communities' vulnerability to hazards such as drought and long-term climate change. The arid southwestern Phoenix metropolitan area is illustrative of the challenges that developed urban areas in arid climates face globally as population growth and climate change stress already fragile human-environmental systems. This thesis reveals the factors abating and exacerbating differential community water system vulnerability to water scarcity in communities simultaneously facing drought and rapid peri-urban growth. Employing a grounded, qualitative comparative case study approach, this thesis explores the interaction of social, biophysical and institutional factors as they effect the exposure, sensitivity and adaptive capacity of community water systems in Cave Creek and Buckeye, Arizona. Buckeye, once a small agricultural town in the West Valley, is wholly dependent on groundwater and currently planning for massive development to accommodate 218,591 new residents by 2020. Amid desert hills and near Tonto National Forest in the North Valley, Cave Creek is an upscale residential community suffering frequent water outages due to aging infrastructure and lack of system redundancy. Analyzing interviews, media accounts and policy documents, a narrative was composed explaining how place based factors, nested within a regional institutional water management framework, impact short and long-term vulnerability. This research adds to the library of vulnerability assessments completed using Polsky et al.'s Vulnerability Scoping Diagram and serves a pragmatic need assisting in the development of decision making tools that better represent the drivers of placed based vulnerability in arid metropolitan regions.

Description
This 15-week long course is designed to introduce students, specifically in Arizona, to basic sustainability and conservation principles in the context of local reptile wildlife. Throughout the course, the students work on identifying the problem, creating visions for the desired future, and finally developing a strategy to help with reptile species survival in the valley. Research shows that animals in the classroom have led to improved academic success for students. Thus, through creating this course I was able to combine conservation and sustainability curriculum with real-life animals whose survival is directly being affected in the valley. My hope is that this course will help students identify a newfound passion and call to action to protect native wildlife. The more awareness and actionable knowledge which can be brought to students in Arizona about challenges to species survival the more likely we are to see a change in the future and a stronger sense of urgency for protecting wildlife. In order to accomplish these goals, the curriculum was developed to begin with basic concepts of species needs such as food and shelter and basic principles of sustainability. As the course progresses the students analyze current challenges reptile wildlife faces, like urban sprawl, and explore options to address these challenges. The course concludes with a pilot pitch where students present their solution projects to the school.

Description
Global climate change (GCC) is among the most important issues of the 21st century. Adaptation to and mitigation of climate change are some of the salient local and regional challenges scientists, decision makers, and the general public face today and will be in the near future. However, designed adaptation and mitigation strategies do not guarantee success in coping with global climate change. Despite the robust and convincing body for anthropogenic global climate change research and science there is still a significant gap between the recommendations provided by the scientific community and the actual actions by the public and policy makers. In order to design, implement, and generate sufficient public support for policies and planning interventions at the national and international level, it is necessary to have a good understanding of the public's perceptions regarding GCC. Based on survey research in nine countries, the purpose of this study is two-fold: First, to understand the nature of public perceptions of global climate change in different countries; and secondly to identi-fy perception factors which have a significant impact on the public's willingness to sup-port GCC policies or commit to behavioral changes to reduce GHG emissions. Factors such as trust in GCC information which need to be considered in future climate change communication efforts are also dealt with in this dissertation. This study has identified several aspects that need to be considered in future communication programs. GCC is characterized by high uncertainties, unfamiliar risks, and other characteristics of hazards which make personal connections, responsibility and engagement difficult. Communication efforts need to acknowledge these obstacles, build up trust and motivate the public to be more engaged in reducing GCC by emphasizing the multiple benefits of many policies outside of just reducing GCC. Levels of skepticism among the public towards the reality of GCC as well as the trustworthiness and sufficien-cy of the scientific findings varies by country. Thus, communicators need to be aware of their audience in order to decide how educational their program needs to be.

Description
There are three known materials that readily undergo fission, allowing their use as a base for nuclear fuel: uranium-235, a naturally-occurring but uncommon isotope; plutonium, created from irradiated natural uranium; and uranium-233, produced from thorium. Of the three, uranium-235 and plutonium feature heavily in the modern nuclear industry, while uranium-233 and the thorium fuel cycle have failed to have significant presence in the field. Historically, nuclear energy development in the United States, and thorium development in particular, has been tied to the predominant societal outlook on the field, and thorium was only pursued seriously as an option during a period when nuclear energy was heavily favored, and resources seemed scarce. Recently, thorium-based energy has been experiencing a revival in interest in response to pollution concerns regarding fossil fuels. While public opinion is still wary of uranium, thorium-based designs could reduce reliance on fossil fuels while avoiding traditional drawbacks of nuclear energy. The thorium fuel cycle is more protected against proliferation, but is also much more expensive than the uranium-plutonium cycle in a typical reactor setup. Liquid-fueled molten salt reactor designs, however, bypass the prohibitive expense of U-233 refabrication by avoiding the stage entirely, keeping the chain reaction running with nothing but thorium input required. MSRs can use any fissile material as fuel, and are relatively safe to operate, due to passive features inherent to the design.

Description
This thesis examines how the wording of proposed government policies can affect the level of public support that a given policy generates. By surveying 158 Phoenix residents, I tested the differing degrees of support that voters would have for a proposed city ordinance, which would stop Homeowners' Associations from restricting the use of native desert plants in residential landscaping. The ordinance was framed in the survey as a self-governance issue or a water conservation issue. I found that the message frames had little effect on the overall level of support for the ordinance, since most residents had moderate support for the policy. However, participants who were either residents of Homeowners' Associations that did not have native plant restrictions, or native residents of Arizona, demonstrated greater levels of support for the self-determination frame of the proposed ordinance. These findings have implications for policy makers who use targeted messages to establish pro-environmental policies at the local level.

Description
The goal of this paper is to serve as a case-study of the youth climate movement at the local level, focusing on how young activists and organizers in Arizona perceive their pathways, motivators, and barriers in the climate movement. In order to answer my research question of ‘What are the different experiences of Arizona youth activists’ involvement in climate action?’, I conducted a case-study of 15 interviews with participants between the ages of 18-25 that varied in racial and gender identity, as well as the duration of their involvement. While this paper does not present a comprehensive view of all experiences of youth climate activists and organizers in Arizona, these interviews highlight the upbringing, background, and the degree of involvement of young climate organizers and activists, ultimately revealing their similar yet unique experiences in the climate movement. Even though further research, discussion, and opportunities are needed to better understand the youth climate movement as well as other emerging social movements, these participants represent the heart of the movement here in Arizona. This case-study sheds light on lived-experiences and urges readers to consider young climate activists and organizers’ varying perspectives on how to support, amplify, and implement their requests for a livable, intersectional, diverse, and inclusive future.

Description
Environmental activism has played a major role in American politics since the late 1800s, with major victories including the National Park Service Organic Act of 1916 that established the National Park Service to help protect parks and monuments, the Clean Air and Clean Water Acts of the 1960s and 1970s, and the phase-out of ozone depleting chemicals in the 1990s. Yet mainstream activism has stagnated in recent years, facing a variety of problems such as continuing to perpetuate a corporate system in which frontline and minority communities are left behind and only focusing on traditional methods like lobbying and indirect activism that fail to generate mass public support. In contrast, the Sunrise Movement is a new youth-oriented environmental and social organization that has become prevalent in the last five years for their aim to combat both climate change and socioeconomic inequalities through the Green New Deal. With the growing need for climate action that is fair and equitable, this project intended to contextualize the Sunrise Movement within past and current environmental movements as well as the current environmental and political climate in order to then investigate how Sunrise operates and their level of effectiveness in promoting the Green New Deal. I performed a literature review of both past and present news articles as well as journal articles in addition to interviewing experts in the theory and practice of activism to characterize the three waves of environmentalism and lessons learned, the current political sphere and what mainstream activism is working toward, and Sunrise itself. While mainstream and localized radical activism had victories and a certain degree of effectiveness, their lack of inclusivity has failed to encourage the mass mobilization needed for long-term climate legislation. The Sunrise Movement distinguishes itself through disruptive activism and direct engagement: disruptive by challenging the status quo of profit over people, the two party system where both groups are moving toward the right, and the whiteness and liberal locations of the mainstream environmental movement; direct by working with partners across the environmental, social, and labor sphere and working with actionable, hands-on items that encourage participation. Though they have major limitations like ensuring that they are as inclusive as they recognize an environmental movement must be and the risk of being seen as a partisan organization, Sunrise shows that the attitude of the public is moving in favor of the climate and social equity.

Description
Climate change, as it becomes more prevalent, is putting a much harsher strain on the resources of the world, specifically food, energy, and water. With this in mind, now is the time to make a change and begin working towards a more sustainable future for everyone. Arizona is an especially susceptible location that has the opportunity to be the leader of this change. In order to effectively manage this movement through governance, a food-energy-water nexus approach is required. This approach recognizes and accounts for the intricate relationships between these industries in order to promote more resilience and balance throughout the nexus. While the main focus in Arizona tends to be on water, and rightfully so, it is important to understand the intricacies of the food, energy, and water systems together. Right now, the system is fragile and needs a new, more complex approach. Ultimately, legislation that intertwines water rights with agriculture regulation and energy production goals, while also including equity and justice measures, have the capacity to work towards limiting the effects of climate change that Arizona will see. Arizona has the opportunity here to either provide a cautionary tale to other regions of how mismanagement can lead to destruction or can showcase the legislative success that the nexus governance approach can provide.

Description
The purpose of this thesis is to imagine and predict the ways in which humans will utilize technology to feed the world population in the 21st century, in spite of significant challenges we have not faced before. This project will first thoroughly identify and explain the most pressing challenges the future will bring in climate change and population growth; both projected to worsen as time goes on. To guide the prediction of how technology will impact the 21st century, a theoretical framework will be established, based upon the green revolution of the 20th century. The theoretical framework will summarize this important historical event, and analyze current thought concerning the socio-economic impacts of the agricultural technologies introduced during this time. Special attention will be paid to the unequal disbursement of benefits of this green revolution, and particularly how it affected small rural farmers. Analysis of the technologies introduced during the green revolution will be used to predict how 21st century technologies will further shape the agricultural sector. Then, the world’s current food crisis will be compared to the crisis that preceded the green revolution. A “second green revolution” is predicted, and the agricultural/economic impact of these advances is theorized based upon analysis of farming advances in the 20th century.

Description
Journalism is one of the most far-reaching mediums to inform the public about environmental and sustainability issues. Mass communication has brought this discussion to an unprecedented level of exposure that continues to escalate, and the quality of storytelling must continue to spark discussion about sustainability and environmental problems. The quality of environmental journalism, the “researching, verifying, writing, producing and broadcasting of news about the environment” to and for the public sphere, has been a subject of much debate (Pezzullo & Cox, 2012). This beat, relatively new, is an emerging one that serves the public by explaining the importance of protecting and preserving the environment. However, sometimes journalists’ work falls on deaf ears. In order for environmental journalists to be effective storytellers with robust, reliable work that resonates with audiences, they must continue to improve the effectiveness and captivating qualities of their work.
This project will explore how the American public perceives environmental reporting, constraints on its production, an assessment of the industry’s success and growth, and advice from current journalists. I will conclude with a list of the best practices for captivating and effective storytelling. Finally, I will close with a reflection based upon my creative project, a multimedia piece on how citrus crops in Arizona are affected by honey bees. I aim to provide student journalists with an informal guide to the key skills that will help them excel not only in reporting on a certain sustainability topic, but also on the environment as a whole.
