In order to determine what characteristics influence participation in this program I gathered data from multiple sources. I use a panel dataset of household water consumption that spans 12 years of approximately 300,000 homes. I merged this dataset with home structural characteristics, geographical, and demographic context. I then use these characteristics in a linear probability model, with school enrollment zone fixed effects to determine their influence on a household’s probability of participation. School zones are used to control for unobserved characteristics, such as demographics, which are not at a household level. I then utilize these school zone fixed effects in a 2nd stage regression to decompose these elements and analyze their effect on participation.
I find that a household’s water costs, as reflected in the marginal price faced in the summer and the differential between summer and winter water bills, as well as yard size are primary factors that influence participation. I also show that changes in rebate value and water rates can affect different types of households. There is also evidence to support that neighborhood characteristics affect a household’s likelihood of participating.

The integration of Urban Ecological Infrastructure (UEI) has gained attention as cities seek to address challenges posed by urbanization. Constructed treatment wetlands (CTWs), commonly used for removing pollutants from wastewater effluent and storm water runoff, have been proposed as a solution to address challenges posed by rising water challenges. CTWs serve as a unique type of UEI and provide a range of ecosystem services in urban landscapes. With current global concerns over water scarcity and sustainable resource management, wetlands emerge as key components, providing vital ecosystem services, one of which is nutrient filtration. Nitrogen pollution in water bodies poses significant environmental and public health concerns, emphasizing the need for effective mitigation strategies. CTWs present a promising solution for addressing nitrogen pollution in urban settings. However, there are gaps in understanding wetland functioning within arid environments, necessitating arid climate studies to explain nitrogen dynamics. This study, conducted in the Tres Rios Wetland in Phoenix, Arizona, aims to examine nitrogen content in soils. Soil nitrogen content trends from 2019 to 2023 were investigated, with a focus on understanding nitrogen dynamics from inflow to outflow points and comparison from water to shore. There were no trends seen in nitrogen content over time from 2019 to 2023. Additionally, nitrogen levels tended to be higher at the shorelines compared to the open water, likely due to the accumulation of organic matter and soil nitrogen absorption. However, there were no trends observed in nitrogen content from the inflow to outflow points.
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?
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.
1) What do American students know and believe about climate change? How is knowledge related to beliefs?
2) What types of behaviors are students exhibiting that may affect climate change? How do beliefs relate to behavioral choices?
3) Do climate change knowledge, beliefs, and behaviors vary between geographic locations in the United States?
The results of this study begin to highlight the differences between knowledge, beliefs, and behaviors around the United States. First, results showed that students have heard of climate change but often confused aspects of the problem, and they tended to focus on causes and impacts, as opposed to solutions. Related to beliefs, students tended to believe that climate change is caused by both humans and natural trends, and would affect plant and animal species more than themselves and their families. Second, students were most likely to participate in individual behaviors such as turning off lights and electronics, and least likely to take public transportation and eat a vegetarian meal. Individual behaviors seem to be most relevant to this age group, in contrast to policy solutions. Third, students in Illinois felt they would be more likely to experience colder temperatures and more precipitation than those in Arizona, where students were more concerned about rising temperatures.
Understanding behaviors, motivations behind beliefs and choices, and barriers to actions can support pro-environmental behavior change. Educational strategies can be employed to more effectively account for the influences on a young person's belief formation and behavior choices. Providing engagement opportunities with location-specific solutions that are more feasible for youth to participate in on their own could also support efforts for behavior change.
