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
Shifting to renewable energy from fossil fuels is not occurring rapidly. Determining where to locate renewable power plants could help expedite development. The project discussed here uses a GIS ranking tool to determine potential locations for solar and wind power plants in Arizona. Criteria include renewable input (irradiance/wind class), topographic slope, and distance from transmission lines. These are ranked and summed to determine areas with the most potential. The resulting outputs show that there is much more potential land for solar development than wind development. Further analysis in this paper will focus solely on solar due to wind's lower potential. Land sensitivity and ownership are used to assess the feasibility of development. There are many groupings of highly ranked land across the state, but the largest stretch of land runs from outside of Marana (south-central Arizona) northwest to about 60 miles west of Wickenburg (central-west). This regions is mainly on BLM, state, and privately owned land. Some of this land is considered sensitive, but non-sensitive areas with high potential are frequent throughout. Renewable potential in other states could be determined using this tool as well. Variables could be weighted or added depending on each area's need.

Description
The majority of the 52 photovoltaic installations at ASU are governed by power purchase agreements (PPA) that set a fixed per kilowatt-hour rate at which ASU buys power from the system owner over the period of 15-20 years. PPAs require accurate predictions of the system output to determine the financial viability of the system installations as well as the purchase price. The research was conducted using PPAs and historical solar power production data from the ASU's Energy Information System (EIS). The results indicate that most PPAs slightly underestimate the annual energy yield. However, the modeled power output from PVsyst indicates that higher energy outputs are possible with better system monitoring.

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
This project aims to provide a contextualized history of the Sky Harbor Neighborhood Association‟s community collective action efforts. The Sky Harbor Neighborhood (SHN) of East Phoenix is bounded on the West by 24th St., on the East by 32nd St., on the North by Roosevelt St., and the South by Washington Street. SHN is a majority Latino, low-income, working class community (U.S. Census Bureau, 2010) that faces a variety of challenges including low walkability due to inadequate pedestrian infrastructure, low tree coverage, and crime. East Van Buren St., which has a reputation for being one of Phoenix‟s red-light districts, splits the neighborhood in two. In addition, the SHN lacks some key amenities such as grocery stores and is partly considered a food desert by the United States Department of Agriculture (USDA Economic Research Service, 2012).

Description
Freshwater is an essential component of life for most organisms on earth. "Civilization itself is built on a foundation of water (Fagan, 2011)," as people often congregate near water sources, and find innovative solutions to exploit these resources for food production and domestic needs. Rising demand for water due to altered lifestyles and population increase pose further stress on water availability. Alterations and pollution of freshwater ecosystems can dramatically compromise ecological services that many species, among them humans, depend on. Arid places are specifically vulnerable in regards to water, characterized by very low levels of precipitation, as well as many dry months, which are often followed by a short time of severe storms. Considering the interconnectedness of social and ecological systems in regards to freshwater services is crucial in order to sustainably manage freshwater resources and avoid ecological crises that in turn are likely to lead to social crises around the globe (Berkes et. al., 2003).

Description
This thesis looks at the theory and empirical evidence that surrounds the debate between environmentalists and economists regarding the link between trade liberalization and environmental degradation. The main points of the theory are the scale, composition, and technique effects which, when aggregated, are ambiguous as the harm or benefit of trade's effect on the environment. The empirical evidence studied ranges in time periods from the early 1990s to 2011 and mainly focuses on the existence or absence of an environmental Kuznets curve for certain pollutant. However, the data still proves to be inconclusive. The debate about the possible link between trade and the environment is as important as ever, especially in regards to carbon dioxide emissions. Going forward, it is extremely important that international cooperation regarding emissions targets and abatement goals increases. Trade will prove to be an invaluable tool in this endeavor as it provides a mechanism for the spread of green technology as well as can be used as a method of environmental policy enforcement.

Description
The purpose of this research was to address the viability of a monoculture to polyculture agricultural land-cover transition within the context of the palm oil industry in Malaysia and Indonesia. A lifecycle assessment was used as a framework in the Cradle-to-Gate methodology used to understand sustainability hotspots, develop four future scenarios, and to measure three chosen indicators for metric changes. The four scenarios included a business-as-usual, perfect world, and two transition scenarios highlighting greenhouse gases, bio-control chemicals, fertilizer-use, and crop yield as indicators. In the four scenarios, a 1000 ha of plantation land with 140,000 palm oil trees created the backdrop for investigating nutrient cycling, cultivation methods, and the economic trade-offs of a transition. Primary literature was the main source of investigation and a wide-variety of current polyculture research helped create tangible data across the four scenarios. However, polyculture failed to address the socioeconomic barriers present in the governance, business-state, and regulations within this industry and region. An institutional analysis was conducted to investigate the political, financial, and regulatory barriers in this industry and recommend changes. It was concluded that while polyculture is an important form of environmental sustainability and can increase crop yield, the socioeconomic structure of the industry is the largest barrier to change and implement polyculture. In order for this social structure to change, it was recommended that the regulatory institutions, such as the Roundtable for Sustainable Palm Oil (RSPO), reframe their pressure points and instead focus on the interconnectedness of logging and palm oil companies with the regional governments.

Description
Incorporating sustainability education in primary healthcare practice is an important step toward promoting sustainability in the US healthcare system. This health strategy is also consistent with a renewed focus of the US healthcare system, mainly prompted by the Affordable Healthcare Act of 2010, toward preventive care and patient wellness. The major challenge, however, is an effective implementation of sustainability education in the healthcare industry. This honors thesis project developed a sustainability education model, in which primary healthcare providers or the physicians educated the patients about sustainability and its connection to public health issues. The main purpose of this thesis project is to analyze the effectiveness of this sustainability education model and to evaluate its impact on the individuals and households in terms of sustainable attitudes and practices. The study was conducted with 26 parents of newborn babies at Estrella Pediatrics PC using a classic randomized control-group pretest-posttest design. The Pre- and Post-Surveys were completed to evaluate change in their knowledge and attitudes toward sustainability practices covered in the sustainability education model. In the research, the relationships between sustainability-related issues and their negative impacts on the health of human beings were established in the sustainability education pamphlet provided to the physicians, which they shared with the patients during the wellness visits. This pamphlet focused on waste management, air pollution, and locally grown food. Moreover, samples of environmentally-friendly diapers were given to the study respondents to complement this education. The study demonstrated positive trends with the intervention protocol, though the level of statistical significance was marginal. More specifically, it was observed that the respondents placed the highest significance on the education provided by the pediatricians. Interestingly, the receipt of the diaper samples by itself did not generate any significant effect. However, the education provided by the physician and the pamphlet coupled with the diaper gave very positive results. In conclusion, physician led sustainability education has significant potential in promoting sustainability in primary healthcare practice, and further inquiry should be pursued.

Description
Current literature on sustainability education and its core competencies (systems thinking, normative, interpersonal, strategic, and future thinking) has yet to acknowledge the K-12 level, concentrating instead on higher-level institutions. To initiate study at the critical K-12 level, a curriculum module composed of four lessons to address the wicked sustainability problem of drought in the Sonoran Desert was developed, piloted, and evaluated. The framework of each lesson combined the core competencies and the 5Es pedagogy (engage, explore, explain, elaborate, and evaluate). Two lessons were successfully piloted in two seventh grade middle-school science classes in Phoenix, Arizona. Topics addressed were the water cycle, types of drought, water systems, and mitigation methods. Evaluation determined a high level of student engagement. Post-pilot teacher questionnaires revealed a high degree of support for inclusion of sustainability education and core competencies addressing drought in future opportunities. It is concluded that lessons in the future can adopt the core competences of sustainability with the support of educators in Arizona.
