With the projected population growth, the need to produce higher agricultural yield to meet projected demand is hindered by water scarcity. Out of many the approaches that could be implemented to meet the water gap, intensification of agriculture through adoption of advanced agricultural irrigation techniques is the focus for this research. Current high water consumption by agricultural sector in Arizona is due to historical dominance in the state economy and established water rights. Efficiency gained in agricultural water use in Arizona has the most potential to reduce the overall water consumption. This research studies the agricultural sector and water management of several counties in Arizona (Maricopa, Pinal, and Yuma). Several research approaches are employed: modeling of agricultural technology adoption using replicator dynamics, interview with water managers and farmers, and Arizona water management law and history review. Using systems thinking, the components of the local farming environment are documented through socio-ecological system/robustness lenses. The replicator dynamics model is employed to evaluate possible conditions in which water efficient agricultural irrigation systems proliferate. The evaluation of conditions that promote the shift towards advanced irrigation technology is conducted through a combination of literature review, interview data, and model analysis. Systematic shift from the currently dominant flood irrigation toward a more water efficient irrigation technologies could be attributed to the followings: the increase in advanced irrigation technology yield efficiency; the reduction of advanced irrigation technology implementation and maintenance cost; the change in growing higher value crop; and the change in growing/harvesting time where there is less competition from other states. Insights learned will further the knowledge useful for this arid state's agricultural policy decision making that will both adhere to the water management goals and meet the projected food production and demand gap.

Recognition of algae as a “Fit for Purpose” biomass and its potential as an energy and bio-product resource remains relatively obscure. This is due to the absence of tailored and unified production information necessary to overcome several barriers for commercial viability and environmental sustainability. The purpose of this research was to provide experimentally verifiable estimates for direct energy and water demand for the algal cultivation stage which yields algal biomass for biofuels and other bio-products. Algal biomass productivity was evaluated using different cultivation methods in conjunction with assessment for potential reduction in energy and water consumption for production of fuel and feed. Direct water and energy demands are the major focal sustainability metrics in hot and arid climates and are influenced by environmental and operational variables connected with selected algal cultivation technologies. Evaporation is a key component of direct water demand for algal cultivation and directly related to variations in temperature and relative humidity. Temperature control strategies relative to design and operational variables were necessary to mitigate overheating of the outdoor algae culture in panel photobioreactors and sub-optimal cultivation temperature in open pond raceways. Mixing in cultivation systems was a major component in direct energy demand that was provided by aeration in panel bioreactors and paddlewheels in open pond raceways. Management of aeration time to meet required biological interactions provides opportunities for reduced direct energy demand in panel photobioreactors. However, the potential for reduction in direct energy demand in raceway ponds is limited to hydraulics and head loss. Algal cultivation systems were reviewed for potential integration into dairy facilities in order to determine direct energy demand and nutrient requirements for algal biomass production for animal feed. The direct energy assessment was also evaluated for key components of related energy and design parameters for conventional raceway ponds and a gravity fed system. The results of this research provide a platform for selecting appropriate production scenarios with respect to resource use and to ensure a cost effective product with the least environmental burden.

Sustainability has been a growing topic since the 1970’s, but is truly taking shape today as society is beginning to understand the necessity of protecting our environment. Business organizations are following this ‘megatrend’ and are beginning to incorporate sustainable initiatives in their organizations from the inside out. The sports industry is no exception as they are extremely influential over the millions of fans that follow them, whom have a strong affiliation with their favorite team. The Arizona Diamondbacks understand this responsibility and seek to be a leader in their community by creating many sustainable initiatives within their organization and community. The current problem the organization faces, is that much of the community are not aware of their environmental commitment. This is in part due to a lack of marketing within the organization and to the Arizona valley. This project analyzes the sports industry’s commitment to sustainability and how the Arizona Diamondbacks compare to industry leaders. Included is a detailed marketing plan for the organization comprised of current initiatives and of new initiatives that the Diamondbacks could potentially carry out. The implementation of this proposal could deem extremely beneficial as it would strengthen their identity, unify their employees and engage fans, which will make them feel a deeper affiliation with the organization. The Diamondbacks have made a commitment to the environment, but it is time to deepen that commitment, set an example for people in the Valley and in turn, spark social change.

South Mountain is the largest municipal park in the nation. It is a bundled amenity, providing a series of linked services to the surrounding communities. A dataset of 19,209 homes in 155 neighborhoods within three miles of the park was utilized in order to complete a hedonic estimation for two nearby urban villages, Ahwatukee Foothills and South Mountain Village. Measures of access include proximity to the park, trailhead access, and adjacency to the park. Two regressions were estimated, the first including lot characteristics and subdivision fixed effects and the second using the coefficients for each subdivision as the dependent variable. These estimates describe how the location of a house in a subdivision contributes to its conditional mean price. As a result they offer a direct basis for capturing amenities measured at the neighborhood scale on home values. Park proximity, trailhead access and adjacency were found to significantly influence the price of homes at the 5% confidence level in Ahwatukee, but not in South Mountain Village. The results of this study can be applied to issues of environmental justice and park access in determining which areas and attributes of the park are associated with a high premium. Though South Mountain was preserved some time ago, development and future preservation in the City of Phoenix can be informed by such studies.

This paper explores multidisciplinary curricula, services, and experiential learning in higher education on sustainability. Researchers attempt to understand sustainability as a formalized degree program, what frameworks and techniques are used to improve new disciplines, and how Arizona State University's School of Sustainability (SOS) improves sustainability education in higher learning. Secondary research includes a discussion on the history of sustainability as a discipline, the university as a social system, the role of university administration, the roles of professors and students, benchmarking and process improvement for curriculum development, and methods to bridge epistemologies in SOS. The paper presents findings from a study of the SOS undergraduate student experience that used focus groups to gather qualitative data and statistical analysis to analyze that data quantitatively. Study findings indicate that that measuring student perception of SOS's academic services, and understanding the social system of the university, helps administration, faculty, and students collaborate more effectively to enhance learning experiences.

In 2016, in the United States alone, the cosmetics industry made an estimated 62.46 billion dollars in revenue (Revenue of the Cosmetic Industry in the U.S. 2002-2016 | Forecast). With a consistent increase in sales in the last several years, the industry has reached continued success even during times of hardship, such as the Great Recession of 2008. The use of Corporate Social Responsibility (CSR), external campaigns, and thoughtful packaging and ingredients resonates with targeted consumers. This has served as an effective strategy to maintain growth in the industry. Cosmetic companies promote their brand image using these sustainability tactics, but there seems to be a lack of transparency in this unregulated industry. The purpose of this thesis is to determine if the cosmetics industry is a good steward of the sustainability movement. Important terms and concepts relating to the industry will be discussed, then an analysis of sustainability focused cosmetic brands will be provided, which highlights the extent to which these brands engage in activities that promote sustainability. This is followed by an application of findings to a company that could benefit from using such practices. Overall, the analysis of the different brands proved to be shocking and disappointing. This is due to the sheer amount that scored very poorly based on the sustainability criteria developed. The cosmetics industry is too inconsistent and too unregulated to truly act as a good steward for sustainability. Though some companies in the industry succeed, these accomplishments are not consistent across all cosmetic companies. Hence, the cosmetics industry as a good steward for sustainability can only be as strong as its weakest link.

Although the Leadership Scholarship Program has seen successful recruiting processes throughout changes in leadership of the program; the organization expressed a need for major overhaul to reevaluate the decisions of the process and to establish backing for those decisions. By asking current and alumni members of the program about what they would like to see in a future member of the program as well as which parts of the process they found most important, the qualities of a future member of the program could be established and weighted. The goals of the reevaluation were to help eliminate bias, discrepancies between applications with extremely different uncontrollable factors, define points of discrepancies, and establish organizational sustainability while achieving a 100% acceptance rate from offered students. Each of these goals was achieved through methods outlined in the LSP Selection Process Manual that was written as a result of this reevaluation. The manual also outlines ways to improve the process going forward.

Consumption of seafood poses a substantial threat to global biodiversity. Chemical contamination found in both wild-caught and farmed seafood also presents significant health risks to consumers. Flame retardants, used in textiles, upholstery, plastics, and other products to reduce risk of fire-related injury, are of particular concern as they are commonly found in the marine environment and permeate the tissues of fish that are sold for consumption via multiple pathways. The widespread issue of fishery collapse could be alleviated by demonstrating to stakeholders that many unsustainable fish stocks are also unhealthy and mutually disadvantageous for both human consumers and the environment. To thoroughly investigate the confounding factors and contradictory signals enmeshed in the relationship between ecologically sustainable fisheries and flame retardant contamination, I examined the biological characteristics of regional fish stocks which drive both contamination and perceived sustainability. I found that the biological and spatial aspects of commonly consumed aquatic and marine species best predict contamination when compared with various indices of sustainability. My results confirm that knowledge of flame retardant toxicity will become increasingly more important to consumers because a high percentage of global populations rely on coastal seafood for subsistence, and although dispersal of chemical contamination is still a poorly understood phenomenon, fish harvested closer to land are likely to contain higher concentrations of potentially harmful chemicals. Because some of the same biological traits which facilitate the uptake of chemicals also contribute to how a species responds to fishing pressures, concern for private health increases public consideration for the conservation of species at risk.

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.

In this paper, I analyze the costs and benefits of waste prevention and zero waste initiatives that are inflicted upon society. The problem lies in the amount of human municipal solid waste (HMSW) resulting from human activities, especially as growing global urban population estimated to be producing three times as much waste as it does today (Goto, 2014). Landfill externalities are addressed to explain the purpose of this research. Additionally, the efficiency of diverting waste from the landfill is assessed; these diversion methods are recycling, composting, and the uses of TerraCycle. It is important to note the difference between waste prevention and zero waste: Waste prevention is simply reducing the amount of waste, whereas zero waste is aiming to divert HMSW for other uses other than going its final destination, the landfill. This research highlights tax policies and incentive-based approaches that cities currently enforce, as well as repercussions of these approaches. Waste prevention is explored from the user perspective and reactions to taxes on waste that were implemented to promote global sustainability, which can be seen from the primary data collected. I analyze the success of zero waste initiatives in the online marketing agency, Vertical Measures, comparing landfill waste diversion with the implementation of zero waste initiatives. This paper highlights the observations and results from this two-month analysis. With both the analyses of city regulations and first-hand application of zero waste and waste prevention methods, the findings suggest that the success of these initiatives depends on various factors including location and participant attitudes. This research and data can help provide insight for other small businesses for a more sustainable environment and workplace.
