Description
Farmers' markets are a growing trend both in Arizona and the broader U.S., as many recognize them as desirable alternatives to the conventional food system. As icons of sustainability, farmers' markets are touted as providing many environmental, social, and economic benefits, but evidence is mounting that local food systems primarily serve the urban elite, with relatively few low-income or minority customers. However, the economic needs of the market and its vendors often conflict with those of consumers. While consumers require affordable food, farmers need to make a profit. How farmers' markets are designed and governed can significantly influence the extent to which they can meet these needs. However, very little research explores farmers' market design and governance, much less its capacity to influence financial success and participation for underprivileged consumers. The present study examined this research gap by addressing the following research question: How can farmers' markets be institutionally designed to increase the participation of underprivileged consumers while maintaining a financially viable market for local farmers? Through a comparative case study of six markets, this research explored the extent to which farmers' markets in Central Arizona currently serve the needs of farmer-vendors and underprivileged consumers. The findings suggest that while the markets serve as a substantial source of income for some vendors, participation by low-income and minority consumers remains low, and that much of this appears to be due to cultural barriers to access. Management structures, site characteristics, market layout, community programs, and staffing policies are key institutional design features, and the study explores how these can be leveraged to better meet the needs of the diverse participants while improving the markets' financial success.

Description
Energy is a central concern of sustainability because how we produce and consume energy affects society, economy, and the environment. Sustainability scientists are interested in energy transitions away from fossil fuels because they are nonrenewable, increasingly expensive, have adverse health effects, and may be the main driver of climate change. They see an opportunity for developing countries to avoid the negative consequences fossil-fuel-based energy systems, and also to increase resilience, by leap-frogging-over the centralized energy grid systems that dominate the developed world. Energy transitions pose both challenges and opportunities. Obstacles to transitions include 1) an existing, centralized, complex energy-grid system, whose function is invisible to most users, 2) coordination and collective-action problems that are path dependent, and 3) difficulty in scaling up RE technologies. Because energy transitions rely on technological and social innovations, I am interested in how institutional factors can be leveraged to surmount these obstacles. The overarching question that underlies my research is: What constellation of institutional, biophysical, and social factors are essential for an energy transition? My objective is to derive a set of "design principles," that I term institutional drivers, for energy transitions analogous to Ostrom's institutional design principles. My dissertation research will analyze energy transitions using two approaches: applying the Institutional Analysis and Development Framework and a comparative case study analysis comprised of both primary and secondary sources. This dissertation includes: 1) an analysis of the world's energy portfolio; 2) a case study analysis of five countries; 3) a description of the institutional factors likely to promote a transition to renewable-energy use; and 4) an in-depth case study of Thailand's progress in replacing nonrenewable energy sources with renewable energy sources. My research will contribute to our understanding of how energy transitions at different scales can be accomplished in developing countries and what it takes for innovation to spread in a society.

Description
Diarrheal diseases caused by poor water, sanitation and hygiene continue to kill more children in Sub-Saharan Africa's burgeoning informal urban settlements than in any other part of the world. In recent years, Delegated Management Model (DMM), a partnership in which a utility delegates service management to slum residents have been promoted as new models to improve services.
This dissertation examines the benefits of DMM by comparing water services in three informal settlements in Kisumu city, Kenya: two slums where DMM has been implemented, and one, a control, where it has not. In addition, the research examined how school-based hygiene interventions could be designed to improve safe water and hygiene knowledge in urban informal settlements. This study compared outcomes of two approaches to hygiene education, one which combined messages with participatory water testing; the second used hygiene messages alone.
Results of the DMM study showed that DMM implementation had lowered water cost and improved provider accountability. However, unhygienic water collection and handling practices on the part of the service users could contaminate drinking water that was clean at the delivery point, thus preventing the intended health outcomes of DMM from being realized. Results of the hygiene education intervention showed that one week after the inventions, hygiene knowledge among students who received the intervention that combined hygiene messages with participatory water testing was significantly improved. Evaluation of the intervention 12 months after implementation showed that the hygiene knowledge gained was sustained.
The research findings suggest that: i) regular monitoring of water quality at the kiosks is essential to ensure that the DMM model achieves intended health outcomes, ii) sanitation conditions at kiosk sites need to be regulated to meet minimum hygiene standards, and iii) customers need to be educated on safe water collection and storage practices. Finally, school-based hygiene education could be made more effective by including hands-on water testing by students. Making sustainable impact on health and wellbeing of slum residents requires not only building effective partnerships for water delivery, but also paying close attention to the other points of intervention within the water system.

Description
Beneficiary participation has become popular in international development generally, and it is an essential feature of sustainable development. But there are diverse definitions of and motivations for using beneficiary participation, and empirical literature on its effects is underdeveloped. This dissertation aims to clarify what beneficiary participation is and whether there is empirical support for claims about its benefits.
I review historical trends in international development that led to the popularity of both sustainable development and beneficiary participation. This review identifies central themes in defining beneficiary participation and motivations for using it.
I also developed a new typology of beneficiary participation based on a literature review of how scholars define beneficiary participation. I found that the main dimensions of beneficiary participation are (1) participants, (2) channels, (3) types of inputs, (4) timing, and (5) goals. By making these dimensions explicit, this work helps researchers and development practitioners more clearly describe the types of beneficiary participation they study, employ, and advocate for.
To contribute to empirical literature about beneficiary participation, I conducted a case-study of two urban development projects in Bhopal, India. I collected data with a structured survey of project beneficiaries in four slums (two slums from each project) and semi-structured interviews with each project's organizers. And project documents provided secondary data on both projects. The results indicate that local elites did not capture a disproportionate share of either project's benefits, at least with respect to individual household toilets. Because project organizers rather than beneficiaries selected households that would receive toilets, both cases serve as counterexamples to the claim that beneficiaries must intensely participate for projects' benefits to be distributed equitably.
Finally, I review academic literature for empirical evidence that supports claims about the advantages of beneficiary participation. There is relatively strong empirical support for the claim that beneficiary participation improves project outcomes, but empirical support for most other claims (i.e., that it helps make projects more efficient, distribute benefits equitably, and sustain project benefits) is weak. And empirical research suggests that one claimed benefit, empowerment, rarely materializes. In general, more empirical research about beneficiary participation is needed.

Description
The conflict conditions that afflict the livelihoods of Palestinian residents living in the West Bank are embedded within the population's ability to travel more so than any other routine activity. For Palestinian residents, domestic and international travel is a process of following paths riddled with multiple barriers that are both physical and political. Past studies have done well to paint a clear picture of the harsh transportation landscape in the region. However, less attention has focused on how barriers interact to indirectly and directly affect levels of accessibility and well-being. Additionally, suggested development solutions are rarely capable of being successfully implemented given current political conditions. This dissertation uses a systems approach to understand drivers of accessibility challenges in the West Bank and uses the understanding to propose a method to identify transition strategies that may be presently initiated whilst maintaining the ability to provide adequate benefit. The research question informing the study asks, How do drivers influencing the issue of poor accessibility and well-being in the West Bank persist and interact, and how might solutions be approached? The dissertation approaches the question in four sequential actions that each produces a functional planning deliverable. First, a system map that depicts the drivers and influences to the problem of poor accessibility and well-being is constructed (Chapter 4). Second, a future vision for the transportation system in the West Bank is identified (Chapter 5). Third, the system map and vision are used to assess how conflict conditions affect transition research (Chapter 6). Finally, the previous three deliverables are used to suggest a guide for transition management for transportation development in the West Bank (Chapter 7). Combinations of four different data sets, including an extensive review of published literature, field observations, individual field expert interviews, and group commuter interviews inform the research. Additionally, the Transformational Sustainability Research framework provides a normative base for the steps taken throughout the research. Ultimately, the dissertation presents an interpretation of information that has theoretical and practical application potential in transformational sustainability research and development efforts in the region respectively.

Description
ABSTRACT Water resources in many parts of the world are subject to increasing stress because of (a) the growth in demand caused by population increase and economic development, (b) threats to supply caused by climate and land cover change, and (c) a heightened awareness of the importance of maintaining water supplies to other parts of the ecosystem. An additional factor is the quality of water management. The United States-Mexican border provides an example of poor water management combined with increasing demand for water resources that are both scarce and uncertain. This dissertation focuses on the problem of water management in the border city of Ciudad Juarez, Chihuahua. The city has attracted foreign investment during the last few decades, largely due to relatively low environmental and labor costs, and to a range of tax incentives and concessions. This has led to economic and population growth, but also to higher demand for public services such as water which leads to congestion and scarcity. In particular, as water resources have become scarce, the cost of water supply has increased. The dissertation analyzes the conditions that allow for the efficient use of water resources at sustainable levels of economic activity--i.e., employment and investment. In particular, it analyzes the water management strategies that lead to an efficient and sustainable use of water when the source of water is either an aquifer, or there is conjunctive use of ground and imported water. The first part of the dissertation constructs a model of the interactive effects of water supply, wage rates, inward migration of labor and inward investment of capital. It shows how growing water scarcity affects population growth through the impact it has on real wage rates, and how this erodes the comparative advantage of Ciudad Juarez--low wages--to the point where foreign investment stops. This reveals the very close connection between water management and the level of economic activity in Ciudad Juarez. The second part of the dissertation examines the effect of sustainable and efficient water management strategies on population and economic activity levels under two different settings. In the first Ciudad Juarez relies exclusively on ground water to meet demand--this reflects the current situation of Ciudad Juarez. In the second Ciudad Juarez is able both to import water and to draw on aquifers to meet demand. This situation is motivated by the fact that Ciudad Juarez is considering importing water from elsewhere to maintain its economic growth and mitigate the overdraft of the Bolson del Hueco aquifer. Both models were calibrated on data for Ciudad Juarez, and then used to run experiments with respect to different environmental and economic conditions, and different water management options. It is shown that for a given set of technological, institutional and environmental conditions, the way water is managed in a desert environment determines the long run equilibrium levels of employment, investment and output. It is also shown that the efficiency of water management is consistent with the sustainability of water use and economic activity. Importing water could allow the economy to operate at higher levels of activity than where it relies solely on local aquifers. However, at some scale, water availability will limit the level of economic activity, and the disposable income of the residents of Ciudad Juarez.

Description
Large-scale land acquisition (LaSLA), also called "land grabbing" refers to the buying or leasing of large tracts of land, especially in Sub-Saharan Africa (SSA) by foreign investors to produce food and biofuel to send back home. Since 2007, LaSLA has become an important development issue due to the opportunities and threats for SSA countries. LaSLA has the potential to create local jobs, transfer technology, build infrastructure, and modernize SSA's agriculture. Nonetheless, it can also aggravate food insecurity, perpetuate corruption, degrade ecosystems, cause conflicts, and displace local communities. What drives LaSLA, what are its impacts on local people, and under what circumstances can we consider it as just and ethical?
To examine what drives LaSLA, I used country level data from 2005 to 2013 on economic conditions, natural resources, business practices, and governance to estimate LaSLA models. I find that LaSLA increases with increasing government effectiveness, land prices, and the ease of doing business, and decreases with stronger regulatory regimes. To assess LaSLA's impacts on local people, I conducted a comparative case study in Tanzania. I compare changes in peoples' livelihood between treatment villages (those experiencing LaSLA) and control villages (those without LaSLA projects). The results show that under current practices, the risks of LaSLA outweigh the benefits to local livelihoods, yet there are potential benefits if LaSLA is implemented correctly.
To philosophically examine whether LaSLA can be considered just and ethical, I apply John Rawls' theory of justice. The analysis indicates that from both procedural and distributive justice perspective, LaSLA currently fails to satisfy Rawlsian principles of justice. From these analyses, I conclude that if implemented correctly, LaSLA can produce a win-win outcome for both investors and host countries. I suggest that strong governance, rigorous environmental and social impact assessment, and inclusion of local people at all levels of LaSLA decision making are critical for sustainable and equitable outcomes.

Description
Producing, transforming, distributing, and consuming food requires a multitude of actors, from the microbes in the soil to the truck drivers, from the salesperson to the bacterial life that supports digestion. Yet, the global food system – far from being neutral – unequally provides and extracts resources around the globe to serve and protect the needs of some, while excluding and/or oppressing others and producing trauma in the process. Drawing on feminist scholarship and permaculture research – two fields that discuss the importance of care but only rarely work together – and using social science methods, I explore how to integrate care into food systems, and what are the outcomes of such an integration. I first bring together the voices of 35 everyday experts from Cuba, France, and the United States (Arizona) and perspectives from ethics of care, creation care, indigenous scholars, and permaculture specialists, and I use grounded theory to develop a definition of care in food systems context, and a conceptual map of care that identifies motives for caring, caring practices and their results. I then discuss how caring practices enhance food systems’ adaptive capacity and resilience. Next, I study the relationship between a subset of the identified caring practices – what is recognized as “Earth care” – and their effect on well-being in general, and Food Well-Being more specifically, using three case studies from Arizona based on: (1) interviews of school teachers, (2) interviews of sustainable farmers, (3) a survey with 96 gardeners. There, I also discuss how policies and cultural transformations can better support the integration of Earth care practices in food systems. Then, I examine how urban food autonomy movements are grassroots examples of integration of care in food systems, and how through their care practices – Earth care, “People care” and “Fair share” – they can serve as a catalyst for social change and contribute to the achievement of the United Nations Sustainable Development Goals. Lastly, I conclude with recommendations to strengthen a culture of care in food systems, as well as limitations to my research, and future research directions.

Description
Food waste is one of the most significant food system inefficiencies with environmental, financial, and social consequences. This waste, which occurs more at the consumer stage in high income countries, is often attributed to consumers’ behavior. While behavior is a contributing factor, the role of other contextual factors in influencing this behavior has not been systematically analyzed. Understanding contextual drivers of consumer food waste behavior is important, as behavior sits in a matrix of technology, infrastructures, institutions and social structure. Hence designing effective interventions will require a systems perceptive of the problem. In paper 1, I used Socio-ecological framing to understand how personal, interpersonal, socio-cultural, built, and institutional environments contribute to food waste at the consumer stage. In paper 2, I explored the perception of stakeholders in Phoenix on the effectiveness and feasibility of possible interventions that could be used to tackle consumer food waste. In paper 3, I examined the impact of knowledge and awareness of the environmental consequence of food waste in terms of embedded water and energy on the cognitive factors responsible for consumer food waste behavior. Across these three papers, I have identified three findings. First, the most influential factor responsible for consumer food waste is meal planning, as many decisions about food management depend on it. However, there are many contextual factors that discourage meal planning. Other factors identified include the wide gap between food producers and consumers, the low price of food, and marketing strategies used by retailers to encourage food purchases. Systems level interventions will be required to address these drivers that provide an enabling environment for behavioral change. Second stakeholders in the city overwhelmingly support and agree that education will be the most effective and feasible intervention to address consumer food waste, 3) there is need to carefully craft education materials to inform consumers about other resources, such as water and energy, embedded in food waste to stimulate a personal norm that motivates change in behavior. In this study, I emphasize the need to understand the root causes of consumer food waste and exploration of systems level interventions, in combination with education and information interventions that are being commonly used.

Description
The science community has made efforts for over a half century to address sustainable development, which gave birth to sustainability science at the turn of the twenty-first century. Along with the development of sustainability science during the past two decades, a landscape sustainability science (LSS) perspective has been emerging. As interests in LSS continue to grow rapidly, scholars are wondering what LSS is about and how LSS fits into sustainability science, while practitioners are asking how LSS actually contributes to sustainability in the real world. To help address these questions, this dissertation research aims to explore the currently underused problem-driven, diagnostic approach to enhancing landscape sustainability through an empirical example of urbanization-associated farmland loss (UAFL). Based mainly on multimethod analysis of bibliographic information, the dissertation explores conceptual issues such as how sustainability science differs from conventional sustainable development research, and how the past, present, and future research needs of LSS evolve. It also includes two empirical studies diagnosing the issue of urban expansion and the related food security concern in the context of China, and proposes a different problem framing for farmland preservation such that stakeholders can be more effectively mobilized. The most important findings are: (1) Sustainability science is not “old wine in a new bottle,” and in particular, is featured by its complex human-environment systems perspective and value-laden transdisciplinary perspective. (2) LSS has become a vibrant emerging field since 2004-2006 with over three-decade’s intellectual accumulation deeply rooted in landscape ecology, yet LSS has to further embrace the two featured perspectives of sustainability science and to conduct more problem-driven, diagnostic studies of concrete landscape-relevant sustainability concerns. (3) Farmland preservationists’ existing problem framing of UAFL is inappropriate for its invalid causal attribution (i.e., urban expansion is responsible for farmland loss; farmland loss is responsible for decreasing grain production; and decreasing grain production instead of increasing grain demand is responsible for grain self-insufficiency); the real problem with UAFL is social injustice due to collective action dilemma in preserving farmland for regional and global food sufficiency. The present research provides broad implications for landscape scientists, the sustainability research community, and UAFL stakeholders.
