Description
Phosphorus (P), an essential element for life, is becoming increasingly scarce, and its global management presents a serious challenge. As urban environments dominate the landscape, we need to elucidate how P cycles in urban ecosystems to better understand how cities contribute to — and provide opportunities to solve — problems of P management. The goal of my research was to increase our understanding of urban P cycling in the context of urban resource management through analysis of existing ecological and socio-economic data supplemented with expert interviews in order to facilitate a transition to sustainable P management. Study objectives were to: I) Quantify and map P stocks and flows in the Phoenix metropolitan area and analyze the drivers of spatial distribution and dynamics of P flows; II) examine changes in P-flow dynamics at the urban agricultural interface (UAI), and the drivers of those changes, between 1978 and 2008; III) compare the UAI's average annual P budget to the global agricultural P budget; and IV) explore opportunities for more sustainable P management in Phoenix. Results showed that Phoenix is a sink for P, and that agriculture played a primary role in the dynamics of P cycling. Internal P dynamics at the UAI shifted over the 30-year study period, with alfalfa replacing cotton as the main locus of agricultural P cycling. Results also suggest that the extent of P recycling in Phoenix is proportionally larger than comparable estimates available at the global scale due to the biophysical characteristics of the region and the proximity of various land uses. Uncertainty remains about the effectiveness of current recycling strategies and about best management strategies for the future because we do not have sufficient data to use as basis for evaluation and decision-making. By working in collaboration with practitioners, researchers can overcome some of these data limitations to develop a deeper understanding of the complexities of P dynamics and the range of options available to sustainably manage P. There is also a need to better connect P management with that of other resources, notably water and other nutrients, in order to sustainably manage cities.

Description
There are two main sections of this thesis: Codebook development and case coding. Over the course of my two years of involvement with the collaborative governance lab with Drs. Schoon and Carr Kelman, I worked on helping to complete the coding manual built by the lab to test variables from the literature using case studies. My main deliverable was building a Qualtrics survey to collect case studies. Using this Qualtrics survey, the lab will be able to collect coded cases by distributing the survey link through research networks. My thesis project included building the interface for the survey, participating in testing the intercoder reliability of the codebook, and coding one case, the Four Forest Restoration Initiative (4FRI), to provide insight on the collaborative governance strategies of this collaboration. Coding 4FRI also acted as a preliminary test of the survey, helping to provide further information on how users of the codebook might interact with the survey, and allowing the lab to generate a test report of survey results.

Description
As a cause of negative economic, societal, and environmental effects, food waste is increasingly being seen as a sustainability issue that needs to be addressed. Reduction of food waste is preferred to recycling because it reduces the financial burden and technological innovations needed to address the issue. While there are many different approaches to reduce food waste, this paper investigates dynamic social norms as an avenue for reducing food waste. Recent studies showcased the effectiveness of using dynamic social norms to reduce meat consumption and the use of to-go cups. However, there appears to be a gap in research that investigates the impact of dynamic social norms in U.S. university community dining settings. This study piloted the use of dynamic social norms to intervene in post-consumer food waste behaviors at Arizona State University. Specifically, this study compared food waste amounts in a location with and without an intervention tool as well as conducted interviews to monitor any self-reported behavior change. Results show that dynamic social norms can promote behavior change in terms of food waste when compared to a control location without the intervention. Further, this study advocates for monitoring food habits through both quantitative and qualitative analysis in order to identify potential behavior changes that could not be captured to the same extent by a mono-methodological approach.

The policy design process in the United States has been guiding policymakers for decades. In order to keep up with the developing sustainability challenges that the US is facing, a new method of policy design needs to be determined for long-lasting, sustainable change. Human-centered design principles provide a new, unique perspective for analyzing sustainability challenges. Through the integration of human-centered design principles into policy systems, a new framework for policy design can be created. Through this project, a new framework that allows for the adaptation to new technologies, scientific information, and developments in the sustainability crisis to be accounted for and adequately addressed in future policies has been created.

Student housing at American universities have been compared to prison cells in pop culture ad nauseum, but how far does this joke actually reflect reality? Most freshmen are required to live in student housing for their first year of college, yet these spaces are most notorious for having small windows, tightly packed beds, questionable food access, thin walls, and little ability for customization. Impacting the sight, touch, taste, sound, and speech of residents, respectively, these living conditions unavoidably impact the on-campus freshman experience in an integral way and deserve more intentionality of their design. The marketed purpose of offering housing and requiring on-campus living by universities is to ensure students are able to form a community and connect to campus as soon as they arrive. Yet, to what extent does this university-held goal to retain students fail when the goals of individual students do not have conditions in which to be successful? To what extent do the goals of the university actually hold students prisoner to a poorly designed system?

Description
The cosmetic industry has a significant lack of data on sustainability practices. The global market for cosmetics is expected to grow from $288 billion in 2021 to $415 billion in 2028 as more people populate the globe (Cosmetics Market Size, Share, & COVID-19 Impact Analysis, 2022). This research paper analyzes sustainability within the cosmetic industry. Specifically, comparing the practices between The Body Shop and Bath & Body Works. To test the hypothesis that The Body Shop is more sustainable than Bath & Body Works, a case study analysis was conducted to measure the companies’ performance in the environmental, economic, and social sectors. Comparable metrics were selected, and a pairwise comparison was completed to weigh the different metrics. To analyze the results, the Analytic Hierarchy Process (AHP) was used to ensure consistency in metric weights, and a Mann-Whitney U test was used to analyze the sector's final weights. The results verified the hypothesis that The Body Shop was more sustainable than Bath & Body Works. In all, the results support the idea that the cosmetic industry needs stronger regulations and oversight of cosmetic companies’ sustainability impact. One of the most prevalent limitations of this study is the lack of transparency and information from cosmetic companies. Moving forward, it is recommended to use data from multiple years with key performance indicators (KPIs) to assess sustainability performance more accurately.

Phosphorus (P) is an essential resource for global food security, but global supplies are limited and demand is growing. Demand reductions are critical for achieving P sustainability, but recovery and re-use is also required. Wastewater treatment plants and livestock manures receive considerable attention for their P content, but municipal organic waste is another important source of P to address. Previous research identified the importance of diverting this waste stream from landfills for recovering P, but little has been done to identify the collection and processing mechanisms required, or address the existing economic barriers. In my research, I conducted a current state assessment of organic waste management by creating case studies in Phoenix, Arizona and New Delhi, India, and surveyed biomass energy facilities throughout the United States. With participation from waste management professionals I also envisioned an organic waste management system that contributes to sustainable P while improving environmental, social, and economic outcomes.
The results of my research indicated a number of important leverage points, including landfill fees, diversion mandates for organic waste, and renewable energy credits. Source separation of organic waste improves the range of uses, decreases processing costs, and facilitates P recovery, while creating jobs and contributing to a circular economy. Food is a significant component of the waste stream, and edible food is best diverted to food banks, while scraps are best given to livestock. Biomass energy systems produce multiple revenue streams, have high processing capacities, and concentrate P and other minerals to a greater extent than composting. Using recovered P in urban agriculture and native landscaping results in additional benefits to social-ecological systems by improving food security, reducing the urban heat island effect, sequestering carbon, and enhancing urban ecosystems.

Description
The clock is ticking for the global community to attain the United Nations' Sustainable Development Goals (SDGs) by 2030, underscoring the urgent need for enhanced efforts to address the interconnected challenges outlined in the seventeen comprehensive SDGs.
In this context, philanthropy emerges as a critical driver of positive change, playing a pivotal role in advancing social change and sustainable development. Partnered philanthropy, a rising trend within the philanthropic sector characterized by collaborative approaches to grantmaking, is a promising approach to achieving the SDGs.
This study examines the effectiveness, challenges, and opportunities associated with partnered philanthropy in attaining the SDGs. By analyzing current practices and outcomes, the study offers actionable recommendations for leveraging partnered philanthropy to accelerate progress toward a sustainable and equitable future.
Building upon the proposed actions and acknowledging the challenges, one key recommendation outlined in this study is the importance of implementing a framework to guide collaborative philanthropic efforts in this space more effectively. Tracking the progress of the SDGs is a highly data-driven process, relying on extensive statistics and evidence to paint a comprehensive picture, enabling the global community to understand how far they still need to go. While extensive targets and data exist for private sector entities pursuing the SDGs, the philanthropic sector lacks a comparable framework for tracking progress, highlighting the need for a more structured approach.
This study focuses on the role of partnered philanthropy in advancing SDGs 6 and 7, revealing critical insights into the evolving landscape of sustainable development initiatives. These findings offer guidance for concerned stakeholders and serve as a roadmap for accelerating progress toward a more sustainable future.
