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.

Description
From 2007 to 2017, the state of California experienced two major droughts that required significant governmental action to decrease urban water demand. The purpose of this project is to isolate and explore the effects of these policy changes on water use during and after these droughts, and to see how these policies interact with hydroclimatic variability. As explanatory variables in multiple linear regression (MLR) models, water use policies were found to be significant at both the zip code and city levels. Policies that specifically target behavioral changes were significant mathematical drivers of water use in city-level models. Policy data was aggregated into a timeline and coded based on categories including user type, whether the policy was voluntary or mandatory, the targeted water use type, and whether the change in question concerns active or passive conservation. The analyzed policies include but are not limited to state drought declarations, regulatory municipal ordinances, and incentive programs for household appliances. Spatial averages of available hydroclimatic data have been computed and validated using inverse distance weighting methods. The data was aggregated at the zip code level to be comparable to the available water use data for use in MLR models. Factors already known to affect water use, such as temperature, precipitation, income, and water stress, were brought into the MLR models as explanatory variables. After controlling for these factors, the timeline policies were brought into the model as coded variables to test their effect on water demand during the years 2000-2017. Clearly identifying which policy traits are effective will inform future policymaking in cities aiming to conserve water. The findings suggest that drought-related policies impact per capita urban water use. The results of the city level MLR models indicate that implementation of mandatory policies that target water use behaviors effectively reduce water use. Temperature, income, unemployment, and the WaSSI were also observed to be mathematical drivers of water use. Interaction effects between policies and the WaSSI were statistically significant at both model scales.

Description
In today's world, critical thinking and using a systems approach to problem solving are skills that are far too rare. In the age of information, the truth has become muddled by "fake news" and a constant barrage of exaggerations or blatant falsehoods. Without critical thinking skills, "many members of our society do not command the scientific literacy necessary to address important societal issues and concerns" (NCES 2012, p.11). Additionally, far too many people are incapable of thinking long term and understanding how their actions affect others. Because of this shortsightedness our world is facing one of its biggest ecological crises \u2014 global warming confounded by overpopulation and overconsumption. Now, more than ever, it is critical "for our young people to have a basic understanding of the relevant scientific ideas, technologies and ethical issues and powers of reasoning, to be prepared to face these issues" (Harlen et al., 2015). I believe that investigating innovative ways to teach ecology could be an important step to accomplishing this. Learning to think like a scientist forces people to rely on facts, follow similar protocols to deduce these facts, and be able to think critically about misleading events. More specifically, ecology education will allow people to develop those skills while also learning about team work, open-mindedness, and their environment. Ecology is defined as "the branch of biology that deals with the relations of organisms to one another and to their physical surroundings" (Dictionary.com, 2018). It is clear that this subcategory of science could act as a powerful introduction to the scientific world and how we relate to it. Its introduction at a young age has the potential to create a generation of conscientious and curious lifelong learners. In an attempt to support effective ways to teach ecology, I developed an educational unit and applied it in different educational contexts. My target audience was elementary aged students and I tested this unit with children in Phoenix Metropolitan Area afterschool programs. I taught core concepts of ecology \u2014 the water cycle, the sun's energy, plants and photosynthesis, and food webs \u2014in a sequence of lesson plans that build upon each other. Finally, I determined the appropriate age group and setting for these lesson plans through research and in-class observations. In this document, I explain the process I went through in developing my lesson plans, why I felt compelled to make them, and my experiences in implementing them.

Description
The ecological benefits provided by trees include improving air quality (Nowak, et. al., 2006), mitigating climate change by sequestering carbon (Nowak, 1993), providing animal habitats (Livingston, et. al., 2003), and reducing heat (Edmonson, 2016), among others. Trees also provide numerous social benefits, impacting urban sustainability in particular by improving human health (Salmond, 2016), aesthetically and economically improving neighborhoods (Torres, 2012), and contributing to thriving communities by creating gathering spaces and even reducing crime (Abraham, et. al., 2010). Because of the tremendous potential of trees to provide social and ecological services, particularly in urban areas, tree planting has become an important facet of many sustainability initiatives. This thesis assesses one such initiative aimed at planting trees for the diverse benefits they provide. Valley Permaculture Alliance (VPA), a nonprofit based in Phoenix, Arizona, is known for its Shade Tree Program. The author conducted an internal, quantitative assessment of the program between August and December of 2015. The assessment included evaluation of several indicators of ecological and community health related to the presence of shade trees, culminating in a report released in 2016. This paper evaluates the use of sustainability indicators in the VPA assessment as well as their value in different types of organizations. It culminates with an assessment of VPA's strengths, challenges faced by the organization, and suggestions for its future development.

Description
On the Arizona-Sonora border, more than 3,000 bodies have been recovered in the 21st century as a result of a fatal government policy that forced migrants into the desert rather than crossing in urban corridors. Humanitarian aid organizations are stretched across thousands of square miles with virtually no resources, particularly in the Cabeza Prieta National Wildlife Refuge (Cabeza Prieta), a deadly wildlife refuge in Arizona's West Desert. A lot is unknown about the West Desert, particularly from a human rights perspective of trying to strategize the distribution of humanitarian aid. One question is of particular importance, where does water already exist in Cabeza Prieta, and what is the quality of that water? In this paper, I will discuss the process of surveying water sources in Cabeza Prieta, display photos and maps to convey what I've learned from my fieldwork, and finally, discuss my findings and delve into a geographical analysis, focusing on the relation between human remains recovery sites and water sources.

Description
As the move towards sustainable urbanism grows, understanding how the city has previously been envisioned and designed will be useful to moving forward. This work examines the legacy of urban design theories, what these theories have implied about what the city should be, and their sustainability consequences. Noticing three prominent urban design visions of the city, the technological city (as proposed in 1922 by Le Corbusier's Ville contemporaine and later in 1933 by his Ville Radieuse (The Radiant City), and in 1935 by Frank Lloyd Wright's' Broadacre City), the social city (as explored in 1961 by Jane Jacobs and in 1976 by Edward Relph of the University of Chicago), and the ecological city (as expounded upon in 1924 by both Lewis Mumford and in 1969 by Ian McHarg), I have newly applied the social-ecological-technical systems framework (SETS) to help classify and analyze these urban design theories and how they have mixed to create hybrid perspectives in more recent urban design theory. Lastly, I have proposed an urban design theory that envisions the sustainable city as an ongoing process. Hopefully, this vision that will hopefully be useful to the future of sustainable development in cities, as will a more organized understanding of urban design theories and their sustainability outcomes.

Description
Pima was not the original name for the tribe of the Native Americans that lived along the Gila River, but their name is only one of many changes this tribe has faced due to the influence of outside sources. Pima was a name given to this tribe by the Spaniards during the 1600s. Throughout history the Pima have fought not only for their rights as a nation, but also for the rights of their beloved river, the Gila River. The relationship between the Pima tribe and Gila River is a very strong and deep connection. In fact, the Pima call themselves A-a'tam, which means "the people," and they identify with the Papago, a historical name for the Indians in the Sonoran Desert. A'kimult, which means "river" was added to their name as well. Being known as the River People may fit perfectly with this tribe due to their close knit and respectful relationship with the river over the decades (Russell, "The Pima Indians, 1975). Today the Pima call the Gila River Indian Community their main Tribal headquarters, which is located south of Phoenix. The Gila River Indian Community (GRIC) is part of both the Pinal and Maricopa counties and has a land area of 583.749 square miles ("Brownfields", 2010). Water deprivation and a bleak agricultural economy are challenges facing the Pima, which historically were strong in both areas. The Gila River has gone from a naturally flowing river to a restricted and nearly dried up waterbed. This research paper will examine the changes that both the Pima and the Gila River have undergone since settlers began to claim land in the late 1800's. It is my goal to look into the natural history and ecology of the Gila River and explain how this change has affected the Pima and their sustainability as a tribe. The ultimate goal is to have information easily accessible for reference for future research projects and to ] provide background information to help implement new programs and projects that will benefit the GRIC. Understanding the relationship between the Gila Valley and Pima will present areas where sustainable projects can improve the economy and society as a whole. The Native Americans who will be specifically addressed during this research are the tribes on the GRIC, which comprise the Akimel O-odham (Pima) and Pee Posh (Maricopa). These communities have a resident population of 15,084 and are located in the Maricopa and Pinal counties of central Arizona, to the south and east of metropolitan Phoenix ("Brownfields", 2010). Today the community is 372,000 acres and varies with an elevation of 935 feet to 1,450 feet ("Gila River", 2012). Literature will be the primary area of research along with informal discussions with employees of the GRIC. The Pimas' beliefs, interests, and practices will be addressed and researched; and review of the literature that deals with each problem they have faced as a result of the changing economy and society. By researching the relationship and proposing new ideas to help maintain the GRIC it will assure that the interests of the Pima are the priority. The potential that this research project can offer must encompass cultural sustainability, which is "developing, renewing and maintaining human cultures that create positive, enduring relationships with other peoples and the natural world" (Hawkes, 2001).

Description
Based on existing research, state wildlife agencies should be diversifying their management activities to reflect both utilitarian and biocentric values. Yet agencies are still focused primarily on managing land and wildlife resources for hunting and fishing, partly because of revenues associated with permits and licenses (Jacobson et al., 2022; Manfredo, 2008). My research examines the values which state agencies emphasize in managing wildlife and engaging the public. Public-facing agency webpages are one way to investigate the values that drive agencies’ management priorities and activities. By looking at how information is represented on their main webpages, one can infer who the intended audience is, and which values guide their actions. Thus, my research aims to analyze how state management activities and associated information—as featured on their websites—represent public wildlife values and the trend away from utilitarianism (especially hunting and fishing) toward protectionism through wildlife conservation. Specifically, I ask: How do state-level wildlife agencies present and communicate wildlife management issues and reflect their different wildlife values—ranging from utilitarianism with emphasis on recreational use and enjoyment by people toward mutualist benefits that also protect wildlife—through their websites?

Description
Urban Ecological Infrastructure (UEI) increases landscape sustainability by meeting multiple socioeconomic and environmental objectives. Community parks are a common form of green or terrestrial UEI that improve access to open space in urban areas. They also provide environmental benefits such as increased biodiversity, pollution filtration, urban heat island mitigation, and rainwater drainage. Decision-makers should consider these factors when siting parks to maximize services, especially since land acquisition involves budget constraints. Geographic information systems (GIS) include various tools that can be used to site parks based on multiple spatial datasets. This research develops a GIS process to identify suitable parcels for parks, filling a gap in the literature through developing a small-scale analysis that considers local context and includes smaller pockets of potential green space in Metro Phoenix, Arizona. This process involved compiling a dataset of socioeconomic and environmental criteria, creating park suitability layers in ArcGIS Pro, and conducting statistical and spatial analyses on the suitability layers. The analysis involved assigning scores to each parcel, where higher scores indicate higher park suitability, and lower scores indicate lower park suitability. Factors that resulted in higher suitability scores were barren land cover, low tree canopy, high surface temperature, in a flood zone, far from existing parks and trails, high percentage of minority and low-income residents, and in an urban area. The resulting maps show significantly higher scores in the southern and western parts of Maricopa County, particularly in and around Gila Bend. While most high-ranking parcels are situated along rural highways, there are many large clusters of high-ranking urban parcels along waterways in Metro Phoenix. Based on this assessment, I recommend park implementation efforts focus on land along the Salt River, Gila River, and Agua Fria River in southern and western Phoenix. Further research could build on this methodology, integrating additional datasets such as walkability scores and experimenting with the parameters to see how the results change.

Description
This thesis explores conservation of threatened and endangered species in the Phoenix metro area using social media. With increased urbanization, rising temperatures, and other issues occurring in the desert landscape, creatures big and small face devastating losses in their populations. Informing the public about the species currently on the brink of extinction allows people to identify the animals in the wild, and may encourage conservation practices that would allow wildlife to thrive far into the future. Utilizing social media as a tool for spreading awareness permits information about Arizona wildlife to be free and easily accessible. This project consists of interviews with conservationists and social media influencers, a survey to understand online behaviors and identify level of interest in the different species, and the creation of consumable social media infographics about the threatened and endangered species of Phoenix. Instagram was selected by survey respondents as the platform they would follow conservation accounts on, leading to the creation of @phxconservation to post the social media infographics. Best practices found by posting on social media in this project can be useful information for conservationists looking to build engagement and effectively inform people.
