Description
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.

Description
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.

Description
This case study explores the institutions and governing strategies involved in the management of Rupa Lake in Kaski district in Western Nepal, particularly Rupa Lake Rehabilitation and Fishery Cooperative. Methods used for data collection include key informant interviews, household interviews, a focus group discussion and archival records. Institutions were examined for their effectiveness in sustaining natural and socioeconomic systems as perceived by community members. Based on a literature review and the results of the data collected, this thesis builds a case study highlighting Rupa Lake Rehabilitation and Fishery Cooperative's strategies for governing its local watershed and formulates a framework for commons institutions that aim to achieve sustainable outcomes. Based on findings, I argue that no single form of governance is a panacea for solving commons problems, governing strategies should be implemented on a case-by-case basis, and institutions should be involved at multiple levels and always include local input. Additionally, a sustainable institution should provide benefits to society that it can see, function democratically and with transparency, promote a biodiverse ecosystem, elevate marginalized groups, and collaborate with other institutions. These "clumsy" institutions create a series of complex interactions that are robust and adaptive to reflect the ever-changing systems they aim to govern.

Description
In this paper, I analyze representations of nature in popular film, using the feminist / deconstructionist concept of a dualism to structure my critique. Using Val Plumwood’s analysis of the logical structure of dualism and the 5 ‘features of a dualism’ that she identifies, I critique 5 popular movies – Star Wars, Lord of the Rings, Brave, Grizzly Man, and Planet Earth – by locating within each of them one of the 5 features and explaining how the movie functions to reinforce the Nature/Culture dualism . By showing how the Nature/Culture dualism shapes and is shaped by popular cinema, I show how “Nature” is a social construct, created as part of this very dualism, and reified through popular culture. I conclude with the introduction of a number of ‘subversive’ pieces of visual art that undermine and actively deconstruct the Nature/Culture dualism and show to the viewer a more honest presentation of the non-human world.

Description
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.

Description
Defines the concept of the arcology as conceived by architect Paolo Soleri. Arcology combines "architecture" and "ecology" and explores a visionary notion of a self-contained urban community that has agricultural, commercial, and residential facilities under one roof. Two real-world examples of these projects are explored: Arcosanti, AZ and Masdar City, Abu Dhabi, UAE. Key aspects of the arcology that could be applied to an existing urban fabric are identified, such as urban design fostering social interaction, reduction of automobile dependency, and a development pattern that combats sprawl. Through interviews with local representatives, a holistic approach to applying arcology concepts to the Phoenix Metro Area is devised.

Description
In this project I analyze Paolo Soleri's concept of arcology \u2014 the combination of architecture and ecology \u2014 from a theoretical, symbolic, and physical perspective. I utilize these three viewpoints to determine what aspects of his theories are most effective for urban design. While his ideas are based on building "arcologies" from the ground up, I will be using the Phoenix Metropolitan area to determine how we could apply his ideas to existing cities without having to rebuild entirely. This past summer I participated in the 5-week construction workshop the Cosanti Foundation offers at the physical prototypical city of Arcosanti in Mayer, Arizona during which time I studied Soleri's work and participated in the construction of the city while also participating in the community dynamic there. I have found that while not all components of Soleri's theories translated well into Arcosanti, there are certainly some ideas that could be applied help to improve the City of Phoenix. I propose improvements to the pedestrian realm and an increase public space with an emphasis on utilizing the infrastructure and land that is already present for future development.

Description
City planners often use bicycle friendly rating schemes as tools to guide them in their efforts to establish a bicycle community. However, the criteria and methodologies used vary from program to program and often do not encapsulate all of the necessary elements that comprise true bicycle friendliness. This report documents the important elements, strategies, and best practices that well-established Dutch, Danish, and German bike friendly cities exhibit to create a baseline standard for bicycle friendliness. Not all rating programs' criteria and methodologies align perfectly within this understanding of bicycle friendliness. City planners should use these programs as tools while keeping their limitations in consideration. The City of Tempe currently uses the League of American Bicyclists Bicycle Friendly Community program and BikeScore.com. By understanding the limitations associated with these programs, Tempe should move forward in their pursuit of bicycle friendliness by using multiple rating programs simultaneously and by looking at top-rated cities' strategies to enhance their infrastructure, network, urban form, and biking culture.

Description
Social relationships are the single most factor that create joy in human lives. And yet, the ways we are building our cities and structuring our lives reduces our chances of interaction and increases isolation. Creating more public spaces may be a possible solution to this problem of declining social cohesion. Public spaces have been shown to improve rates of social cohesion and social interaction. They have also been show to have positive effects on physical health, local economies, the natural environment, reducing crime rates and psychological health. Creating public spaces in areas that are low-income or have limited amounts of space can be very challenging. This paper profiles options of community created spaces, space public spaces and temporary public spaces. All of which are options for low-income and limited space communities. The paper concludes with the summery of an active project to create a public space in such a community through a joint-use agreement.

Description
Modern American environmental social movements have strived for a better world for nearly fifty years, pushing a philosophy of careful resource use and limited consumption as an alternative to the pollution and degradation that has so far accompanied global industrialization. The reach of these movements is broad and the topic they cover is one that aligns with the values and beliefs of many; it is thus quite confusing that they've been so unsuccessful. This thesis was a response to that apparent contradiction, exploring why movements have not been as successful as both they and the public initially desired. It began by defining what social movements are and how they emerge or find success, then provided a brief history of environmentalism in America, and the different successes and failures that occurred before and after the first Earth day in 1970. Finally, it explored some of the reasons environmentalism was unsuccessful, and found that while structural barriers like politics and business interests played a role in movement outcomes, the tactics of different groups were at least partially to blame. Once this was concluded, the author used the perspectives of different activists to propose ways to enhance the quality of current movements and allow them to continue to make progress well into the future. In order to expand the audience of this thesis, the author is also working on a children;s book that illustrates many of the important themes that he hopes to convey to the public. Though drafted, the book is incomplete as of the date that documents are due for Barrett review.
