As sustainability grows in popularity, it is important to understand what may influence people’s perceptions of the environment so that knowledge of how to motivate people to engage in sustainable practices is obtained. This project investigates people's perceptions on green infrastructure in relation to people’s motivation in order to engage in pro-environmental behavior. This study employs an online survey sent to student athletes at Arizona State University followed up by an semi-constructed interview to understand what kind of access these athletes had to green infrastructure while growing up, how much they value the environment today, and whether or not they attribute their current perceptions of the environment to their childhood access to green infrastructure. Findings suggest that there may be a relationship between student athletes’ access to green infrastructure and a higher value of the environment but only in those who are knowledgeable about how green infrastructure can impact the human population. By showing a possible correlation between access to green infrastructure and motivation to conserve the environment, this study shows the importance of environmental design and how the built environment influences people’s perceptions and behavior toward environmental sustainability.

This thesis looks to explore the common barriers and perceptions surrounding sustainable living in westernized societies. We begin by understanding and explaining the complexity and importance of sustainability. Then we go on into a cultural comparison of sustainable lifestyles from places like Mongolia and Northern Arizona. After the comparison, we look deeper into mental barriers, perceptions, and influences that western minds have on the environment and how these beliefs affect their sustainable behaviors. After noticing these obstacles, we were able to research three key solutions to overcoming these barriers: daily practices, contextual motivation, and subjective values. Using these three solutions, this thesis builds out an implementation plan that allows you to help create a more sustainable lifestyle that you can start living out today.

Climate change risks such as rising sea-levels, prolonged droughts, and extreme coastal weather events, are devastating for Small Island Developing States (SIDS) where both their homes and livelihoods are highly interdependent upon the ocean. These SIDS have no other viable choice but to adapt to their ever-changing environments and the rising disaster risks compounded by climate change. Although SIDS tend to receive significant attentions for the adverse impacts of climate change, less is known about the place-based adaptation measures as well as people’s lived experiences with sea-level rise, inundation, tropical storms, droughts, and more. Considering the vast area that the SIDS’ nations cover, the type of climate adaptation measures adopted may vary due to the respective country’s vulnerability and adaptive capacity, as some are more comprehensive and effective than others. This study directly responds to the existing gap in our understanding of how different nations within SIDS are prioritizing and strategizing their adaptation measures with the following research questions: “What are key adaptation strategies practiced in Small Island Developing States (SIDS) to address impacts of climate change? Are there similarities or differences in the adaptation strategies pursued by SIDS?” This study uses a conceptual framework of disaster risk and climate change adaptation developed by the IPCC AR5 (2014) to systematically review over 107 peer-reviewed journal articles, scientific reports, and a few videos. Using a systematic literature view approach as the primary research method, this study assembled, categorized, and analyzed the national as well as sub-national adaptation measures—social, institutional, and structural--of two representative countries: 1) Kiribati (a small, low-lying island with the higher level of exposure and vulnerability to climate change), and 2) Fiji (the second biggest island in the South Pacific known for bigger economy and “High Islands”). The results of the study suggest that the adopted adaptation measures were reflective of the country’s historical legacy and the existing adaptive capacity. While Kiribati has historically focused more on external migration of displaced people and more recently has prioritized structural adaptation practices (e.g., construction of coastal seawall), Fiji has been able to leverage its bigger economy and technical resources to develop more comprehensive institutional, social, and structural adaptation measures. However, it is also important to recognize that the other internal and external factors, mainly geophysical setting (low elevation of Kiribati vs the high islands of Fiji) also contribute the level of vulnerability these nations face.

Located directly south of Pima County, Arizona, there is a culturally rich community known as Santa Cruz County, Arizona. Santa Cruz County is a smaller community being home to an estimated 47,000 people. Santa Cruz County has a rich history given its proximity to the United States-Mexico border. One example of this rich history can be found at the Tumacacori National Historical Park (NHP) with the attractive and unique ruins. The Tumacacori NHP was once an active Spanish mission that oversaw the religious expansion and communal resources. While the Tumacacori NHP no longer operates in this manner, it does serve an important role in providing visitors with a diverse and immersive look into the history of the region and the Tumacacori mission. While the Tumacacori NHP is meant to be a place for all people to visit, most visitors are not from the local community. The reason for this stems from a lack of educational and engagement opportunities between the Tumacacori NHP and the community youth, mainly due to community members being unaware of the park’s existence or the programs that are offered. This project analyzes and uncovers this disconnect as well as the barriers between the Tumacacori NHP and the Santa Cruz County youth through a research study and the use of children’s literature.

Managed Aquifer Recharge is an increasingly prevalent solution to sustain water availability in arid regions. Recharge of groundwater resources using treated wastewater effluent is one type of managed aquifer recharge that offers long-term sustainable water management. However, there are some concerns regarding the reuse of wastewater and its potential to increase exposures to antibiotic resistant bacteria and antibiotic resistance genes that could affect human health. Antibiotic resistance genes can confer the ability for bacteria to resist antibacterial treatment, rendering their presence in water supplies as an area of research needed to evaluate where environmental “hot spots” of potential antibiotic resistance disseminate. To evaluate the occurrence of antibiotic resistant bacteria and antibiotic resistance genes, sampling of an Arizona managed aquifer recharge facility was performed, with target antibiotic resistance genes measured using quantitative polymerase chain reaction. The occurrence of antibiotic resistance genes was evaluated at several sampling wells and in sediments to examine trade-offs between water quantity benefits and water quality issues. The goal of this work is to inform management operations for secure water quality in the face of climate change.
