As inhabitants of a desert, a sustainable water source has always been and will continue to be a crucial component in developing the cities Arizonans call home. Phoenix and the surrounding municipalities make up a large metropolitan area that continues to grow in spatial size and population. However, as climate change becomes more of an evident challenge, Arizona is forced to plan and make decisions regarding its ability to safely and efficiently maintain its livelihood and/or growth. With the effects of climate change in mind, Arizona will need to continue to innovatively and proactively address issues of water management and the effects of urban heat island (UHI). The objective of this thesis was to study the socioeconomic impacts of four extreme scenarios of the future Phoenix metropolitan area. Each of the scenarios showcased a different hypothetical extreme and uniquely impacted factors related to water management and UHI. The four scenarios were a green city, desert city, expanded city into desert land, and expanded city into agricultural land. These four scenarios were designed to emphasize different aspects of the urban water-energy-population nexus, as the future of the Phoenix metropolitan area is dynamic. Primarily, the Green City and Desert City served as contrasting viewpoints on UHI and water sustainability. The Expanded Cities showed the influence of population growth and land use on water sustainability. The socioeconomic impacts of the four scenarios were then analyzed. The quantitative data of the report was completed using the online user interface of WaterSim 5.0 (a program created by the Decision Center for a Desert City (DCDC) at Arizona State University). The different scenarios were modeled in the program by adjusting various demand and supply oriented factors. The qualitative portion as well as additional quantitative data was acquired through an extensive literature review. It was found that changing land use has direct water use implications; agricultural land overtaken for municipal uses can sustain a population for longer. Though, removing agricultural lands has both social and economic implications, and can actually cause the elimination of an emergency source. Moreover, it was found that outdoor water use and reclaimed wastewater can impact water sustainability. Practices that decrease outdoor water use and increase wastewater reclamation are currently occurring; however, these practices could be augmented. Both practices require changes in the publics' opinions on water use, nevertheless, the technology and policy exists and can be intensified to become more water sustainable. While the scenarios studied were hypothetical cases of the future of the Phoenix metropolitan area, they identified important circumscribing measures and practices that influence the Valley's water resources.

Description
Despite similar climate, ecosystem, and population size, the cities of Hermosillo, Mexico and Mesa, USA manage their water very differently. Mesa has a stable and resilient system organized around state and federal regulations. Hermosillo, after rapidly industrializing, has not been able to cope with climate change and long-term drought conditions. Water distribution statistics, stakeholders, policy structure, and government organization were combined in an organizational framework to compare the practices of the two cities. These inputs were weighed against the outcomes and the sustainability of each system. While Mesa is part of a massive metropolitan area, Hermosillo is still developing into a metropolitan center and does not have access to the same infrastructure and resources. In Hermosillo local needs are frequently discounted in favor of broad political goals.

Description
The storm events of summer 2014 proved to be some of the highest on record for Maricopa County. Flash flooding has been an ongoing issue within Arizona during the monsoon season due to the remnants of hurricanes that result in short, high intensity storms. The proximity of these intense storm events and their corresponding flooding structures is imperative in reducing the impact of these events on the community. The analysis of the maximum precipitation events for Tempe, Scottsdale, Phoenix, Mesa, Chandler, Goodyear, Peoria, Avondale and Glendale during the summer of 2014 proved that there were many events that had a calculated recurrence of 100 years or greater. The storm event with the most precipitation events with a recurrence of 100 years or greater was September 8, 2014. This storm event also produced a streamflow response that had the highest recorded streamflow at gages near the events with a 100 year recurrence. These intervals represent a larger amount of rain during a precipitation event and this correlation suggests that short burst of extreme weather was not a trend in this data. Rather, high storm events occurred over the span of 24 hours. The most frequent response of the stream gage to this rain event was a streamflow event that has a recurrence of 2-5 years. This suggests that the channels and flooding structures used to contain the rain events were effective in reducing the amount of water and therefore effectively managing the flooding response. An analysis of newspaper commentary and an interview with a representative from the Flood Control District of Maricopa County (FCDMC) indicated that there is a disconnect between public perception and the structure of FCDMC. Through this analysis a better understanding of the FCDMC as well as the impact of severe storm events in Maricopa County was found.

Description
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.

Our thesis project, blanknationalpark.com, asked one question : how is climate change impacting National Parks in America? We decided to travel to three different areas: Joshua Tree, Glacier and Everglades National Park. It didn’t take long to discover that there was never a definitive answer. The effects of climate change looked different in every park we visited. Joshua Tree was struggling with changes in temperature, climate regime and an increase in fires. The U.S Geological Survey predicted that all of the glaciers in Glacier National Park could be gone by 2030. Everglades National Park was facing the constant threat of sea-level rise, invasive species and stronger hurricanes. However, in every park, one thing was certain - they all would not have their iconic features in the future due to climate change. For our thesis, we created blanknationalpark.com to emphasize the fact that Joshua Tree National Park won’t have Joshua Trees in the coming centuries, glaciers would cease to exist in Glacier National Park and the entire Everglades ecosystem itself will be underwater in the next century and a half. Thus, our project name, “Blank National Park”, pays tribute to the uncertainty of what these famous landscapes could look like in the future. Our main goal was to provide the public with a visual experience that is not only informative but engaging so that we could provide an educational experience about a critical situation without appearing too dismal. We chose to include our last page, ‘Solutions’, to establish hope for the future, and encourage people to take action to help preserve National Parks and the world we live in.

Description
Intensive global animal agricultural practices have proved to be a cause for concern, resulting, in part, from consumer preferences and an increasing global demand for protein, especially meat. Countries like Argentina, contribute to Greenhouse Gas emissions substantially through their livestock sector. Improved resource management can help to promote sustainable agriculture by reducing the amount of water and energy used to produce livestock, and improve livestock practices in order to reduce GHG emissions. The integration of resource management between food, energy, and water systems can help to decrease livestock-based emissions, through efficiency improvements targeted towards animal agricultural practices. This paper can act as a reference for other researchers studying the FEW nexus, to increase their understanding of how to improve coordination across water, energy, and agricultural sectors by using Argentina’s livestock sector as an example. Furthermore, policy and decision makers in Argentina can use information about FEW systems to make informed decisions about the allocation and prioritization of integrated management between food, energy, and water sectors, to help them implement integrated mitigation strategies within their livestock sector to help reduce GHG emissions.
