Description
Making significant progress on the U.N. Sustainable Development Goals (SDGs) needs change agents equipped with key competencies in sustainability. While thousands of sustainability programs have emerged at various educational levels over the past decade, there is, as of yet, no reliable way to assess if these programs successfully convey key competencies in sustainability. This dissertation contributes to addressing this gap in three ways. First, it reviews the body of work on key competencies in sustainability. Based on broad agreement around five key competencies as well as an emerging set of three, an extended framework is outlined that can be used as unified set of learning objectives across sustainability programs. The next chapter reviews the scholarly work on assessing sustainability competencies. Based on this review, a typology of assessment tools is proposed offering guidance to both educators and researchers. Finally, drawing on experience of the four-year “Educating Future Change Agents” project, the last chapter explores the results from a diverse set of competency assessments in numerous courses. The study appraises assessment practices and results to demonstrate opportunities and challenges in the current state of assessing key competencies in sustainability. The results of this doctoral thesis are expected to make a practical and scholarly contribution to the teaching and learning in sustainability programs, in particular with regards to reliably assessing key competencies in sustainability.

Description
In many social-ecological systems, shared resources play a critical role in supporting the livelihoods of rural populations. Physical infrastructure enables resource access and reduces the variability of resource supply. In order for the infrastructure to remain functional, institutions must incentivize individuals to engage in provision and maintenance. The objective of my dissertation is to understand key formal and informal institutions that affect provision of shared infrastructure and the policy tools that may improve infrastructure provision. I examine these questions in the context of irrigation systems in India because infrastructure maintenance is a persistent challenge and system function is critical for global food production.
My first study investigates how the presence of private infrastructure, such as groundwater pumps, affects the provision of shared infrastructure, such as shared tanks or surface reservoirs. I examine whether formal institutions, such as water pricing instruments, may prevent under-provision of the shared tanks. My findings suggest that in the absence of rules that coordinate tank maintenance, the presence of private pumps will have a detrimental effect on system productivity and equality. On the other hand, the combination of a fixed groundwater fee and a location-based maintenance fee for tank users can improve system productivity and equality.
The second study examines the effect of power asymmetries between farmers, caused by informal institutions such as caste, on the persistence of political institutions that govern infrastructure provision. I examined the effect of policy tools, such as non-farm wage employment and informational interventions, on the persistence of two types of political institutions: self-governed and nested. Results suggest that critical regime shifts in political institutions can be generated by either intervening in formal institutions, such as non-farm wage employment, or informal institutions, such as knowledge transmission or learning mechanisms.
The third study investigates how bureaucratic and political corruption affect public good provision. I examine how institutional and environmental factors affect the likelihood of corruption and infrastructure provision. I demonstrate that cracking down on corruption is only beneficial when infrastructure provision is poor. I also show that bureaucratic wages play an important role in curbing extralegal transactions and improving infrastructure provision.

Description
Understanding sustainability worldviews and resulting behaviors is critical to the field of Sustainability Science. As humans face increasingly complex socio-ecological challenges, it is vital to address the lenses through which individuals see the world and act upon. Thus, it is imperative first to understand people's knowledge about and disposition toward sustainability to promote behavioral change. Equally important is acknowledging the cognitive nuances and limitations experienced by individuals attempting to engage in sustainability practices. Studies have shown that cognitive processes, including cognitive dissonance, carry-over effects, moral licensing, and hypocrisy play a significant role in adopting sustainability practices, even amongst sustainability-conscious individuals. In this dissertation, I present a mixed-method exploration of the public's worldviews of sustainability and the cognitive challenges to the adoption of sustainable lifestyles. In my first study, I explore worldviews of sustainability through the development, administration, and quantitative analysis of an online survey. The survey measured five sustainability constructs to explore the sustainability worldviews of a representative sample of the U.S. population (N = 346). Results indicate two separate groups with distinct worldviews: Ambivalents and Sympathizers. Ambivalents tend toward neutral sustainability worldviews, while Sympathizers perceive sustainability more favorably. In study two, I present an analytical autoethnography, shedding light on the attitude-behavior gap in sustainability by focusing on my sustainability worldviews and experiences as a practitioner. Within, I provide an insider's account of the nuances and limitations one experiences while engaging in and striving for a sustainable lifestyle and practices. The autoethnography results reveal the tensions between cognitive processes and the adoption of a sustainable lifestyle. Collectively, my research results offer the sustainability movement insights about possible paradigm shifts toward sustainability based on barriers associated with worldview factors and cognitive processes.

Description
An emerging group of services and activities provided by some State Tourism Offices (STO) called Destination Development (DDev) programs coincides with a growing practitioner shift from promotion to tourism product development. These programs are largely unexplored models for how STO and local destinations might effectively collaborate to create and manage sustainable tourism destinations. Local communities are the innate touchpoint of tourism experiences and the scale at which most negative impacts of tourism naturally occur. Yet many communities lack resources, expertise, and capacity to endogenously plan, develop, and manage sustainable tourism destinations, which creates a need for external actor involvement—involvement that creates equity and power concerns. State organizations are well-positioned to provide accountable support, but little is known about what STOs can do to best catalyze, facilitate, and support sustainable community destinations. Are DDev Programs the key? To better understand the concept and design of DDev programs, as well as the precise role they play in supporting community destination success, an exploratory case study of four US State Tourism Offices that operate DDev Programs was conducted via purposive, in-depth interviews. Themes within and between the cases were identified, and it was discovered that DDev programming largely emerged from the field of rural development; is positioned as a key complement to destination marketing; and has engendered a highly collaborative community of practice that desires greater structure and professional support.

Description
Tucked peacefully into mountains just north of the City of São Paulo, the largest metropolitan area in South America, sits the Cantareira Reservoir System. This massive water catchment network received worldwide coverage in 2014 and 2015 as one of the worst droughts in a century hit the region, threatening to collapse the system. In the years since the peak of the drought, the media has changed its focus, the reservoirs have begun a slow recovery, but the people of the region have had to live with the consequences of this difficult period. Faced with an uncertain future, the people continue to grapple with the historic struggles of rural life, while being faced by new threats to the social, environmental, and technological order that has for a long time stabilized the region. My thesis explores the narrative imaginaries that individuals have pertaining to their personal future and that of the region. It delves into the identity of the Rural Producer, the battle to conserve and preserve native forest, issues surrounding the governance of common resources, and what actors perceive to be the biggest advantages and threats to the sustainable future of the region. Utilizing a set of twenty expert elicitation interviews, data was collected from a variety of actors representing a number of roles and positions within the system. My analysis connects disparate individual narratives, illuminating how they connect together with the narratives of other respondents, creating a regional narrative that illustrates a set of desired outcomes for the region. This paper does not attempt to operationalize solutions for the issues that face the region, it does however serve to provide a context for the historical and contemporary issues that exist, a means by which to consider how they may be approached, and ultimately as a tool for policy makers to make more informed decisions going forward.

Description
The continued reliance on fossil fuel for energy resources has proven to be unsustainable, leading to depletion of world reserves and emission of greenhouse gases during their combustion. Therefore, research initiatives to develop potentially carbon-neutral biofuels were given the highest importance. Hydrothermal liquefaction (HTL, a thermochemical conversion process) of microalgae is recognized as a favorable and efficient technique to produce liquid biofuels from wet feedstocks. In this work, three different microalgae (Kirchneriella sp., Galdieria sulphuraria, Micractinium sp.) grown and harvested at Arizona State University were hydrothermally liquefied to optimize their process conditions under different temperatures (200-375 °C), residence times (15-60 min), solids loadings (10-20 wt.%), and process pressures (9-24 MPa). A one-factor-at-a-time approach was employed, and comprehensive experiments were conducted at 10 % solid loadings and a residence time of 30 min. Co-liquefaction of Salicornia bigelovii Torr. (SL), Swine manure (SM) with Cyanidioschyzon merolae (CM) was tested for the presence of synergy. A positive synergistic effect was observed during the co-liquefaction of biomasses, where the experimental yield (32.95 wt.%) of biocrude oil was higher than the expected value (29.23 wt.% ). Co-liquefaction also led to an increase in the energy content of the co-liquefied biocrude oil and a higher energy recovery rate ( 88.55 %). The HTL biocrude was measured for energy content, elemental, and chemical composition using GC-MS. HTL aqueous phase was analyzed for potential co-products by spectrophotometric techniques and is rich in soluble carbohydrates, dissolved ammoniacal nitrogen, and phosphates. HTL biochar was studied for its nutrient content (nitrogen and phosphorous) and viability of its recovery to cultivate algae without any inhibition using the nutrient leaching. HTL biochar was also studied to produce hydrogen via pyrolysis using a membrane reactor at 500 °C, 1 atm, for 24 h to produce 5.93 wt.% gas. The gaseous product contains 45.7 mol % H2, 44.05 ml % CH4, and 10.25 mol % of CO. The versatile applications of HTL biochar were proposed from a detailed physicochemical characterization. The metal impurities in the algae, bio-oil, and biochar were quantified by ICP-OES where algae and biochar contain a large proportion of phosphorous and magnesium.

Description
Sustainable communities discourse, literature and initiatives have essentially excluded poor marginalized communities at a time when sustainability efforts require more stakeholders and stakeholder involvement. The families in poor marginalized communities of color in the United States are struggling to meet basic needs (food, medicine, shelter, safety). Additionally, in these communities there is a disproportionate level of forced mobility to prisons, jails and detention centers. These communities are unsustainable. This dissertation is comprised of three articles. I present in the first article (published in Sustainability Journal) an argument for a definition of sustainability that includes recognition of the major, complex and persistent problems faced daily by poor marginalized communities of color (African American, Hispanic/Latino, Native American) including those connected to mass incarceration and high recidivism. I also propose a system-of-communities conceptual framework. In my second article, I explore sustainability assessment tools and find them to be inadequate for measuring the progress toward sustainability of poor marginalized communities with high incarceration and recidivism rates. In order to fill this gap, I developed the Building Sustainable Communities Framework and a Social Reintegration, Inclusion, Cohesion, Equity (Social R.I.C.E.) Transition Tool, a qualitative interview guide (a precursor to the development of a community sustainability assessment tool). In the third article, I test the utility of the Building Sustainable Communities Framework and Social R.I.C.E. Transition Tool through a community-based participatory action study: The Building Sustainable Communities-Repairing the Harm of Incarceration Pilot Project. Three types of participants were included, formerly incarcerated, family members of formerly incarcerated and community members. The Restorative Justice Circle process (based on a traditional practice of Native Americans and other indigenous peoples) was also introduced to the groups for the purpose of having discussions and sharing personal stories in a safe, nonthreatening, confidential and equitable space. During the study, data was gathered for reflexive thematic analysis from two participant groups, in-depth interviews, focus groups and short qualitative surveys. The findings reflect the community is in dire need of a path to stability and sustainability and needs the knowledge and tools to help them make collective community decisions about present and future sustainability issues.

Description
Urban community gardens hold the potential to serve as a form of multifunctional green infrastructure to advance urban sustainability goals through the array of ecosystem services they afford. While a substantial body of literature has been produced that is dedicated to the study of these services (e.g., providing fresh produce, promoting socialization, and enhancing urban biodiversity), less attention has been paid to the strategic planning of urban community gardens, particularly in an expansive urban setting, and in the context of the co-benefit of mitigating extreme heat. The research presented in this dissertation explores the potential of community gardens as a form of multifunctional green infrastructure and how these spaces can be planned in a manner that strives to be both systematic and transparent. It focuses on methods that can (1) be employed to identify vacant or open land plots for large metropolitan areas and (2) explores multicriteria decision analysis and (3) optimization approaches that assist in the selection of “green” spaces that serve as both provisioning (a source of fresh fruits and vegetables) and regulating (heat mitigation) services, among others. This exploration involves three individual studies on each of these themes, using the Phoenix metropolitan area as its analytical backdrop. The major lessons from this piece are: (1) remotely sensed data can be effectively paired with cadastral data to identify thousands of vacant parcels for potential greening at a metropolitan scale; (2) a stakeholder-weighted multicriteria decision analysis for community garden planning can serve as an effective decision support tool, but participants' conceptualization of garden spaces resulted in social criteria being prioritized over physical-environmental factors, potentially influencing the provisioning of co-benefits; and (3) optimized urban community garden networks hold the potential to synergistically distribute co-benefits across a large metropolitan area in a manner that systematically prioritizes high-need neighborhoods. The methods examined are useful for all metropolises with a preponderance of open or vacant land seeking to advance urban sustainability goals through green infrastructure.

Description
The food-energy-water (FEW) nexus refers to the interactions, trade-offs, and relationships between the three resources and their related governance sectors. Given the significant interdependencies, decisions made in one sector can affect the other two; thus, integrated governance can reduce unintended consequences and lead towards increased resource security and sustainability. Despite the known benefits, many governance decisions continue to be made in “silos,” where stakeholders do not coordinate across sectoral boundaries. Scholars have begun to identify barriers to the implementation of integrated FEW nexus governance, yet there is still minimal understanding of the reasons why these barriers exist and no theoretical framework for evaluating or assessing FEW nexus governance. Integrating the theory of collaborative governance with the concept of the FEW nexus provides an opportunity to better understand the barriers to and structures of FEW nexus governance and to propose solutions for increased collaborative FEW nexus governance in practice. To investigate this governance system, I examined the collaborative governance of the FEW nexus in the context of extreme urban water challenges in two urban case cities: Phoenix, Arizona, USA and Cape Town, South Africa. First, I performed a media analysis of the 2018 Cape Town water crisis to understand the impact of the water crisis on the FEW nexus resource system and the collaborative governance employed to respond to that crisis. Second, I conducted a systematic case study of FEW nexus governance in Phoenix, Arizona to understand barriers to collaborative governance implementation in the system and to identify opportunities to overcome these barriers. Finally, I presented a framework of indicators to assess the collaborative governance of the local FEW nexus. This dissertation will advance the sustainability literature by moving the concept of FEW nexus governance from theory and conceptualization towards operationalization and measurement.

Description
Globally, rivers are being heavily dammed and over-utilized to the point where water shortages are starting to occur. This problem is magnified in arid and semi-arid regions where climate change, growing populations, intensive agriculture and urbanization have created tremendous pressures on existing river systems. Regulatory incentives have been enacted in recent decades that have spurred river restoration programs in the United States. But what kind of governance does river restoration require that is different from allocative institutional set-ups? Are these recovery programs succeeding in restoring ecological health and resilience of the rivers? Do the programs contribute to social-ecological resilience of the river systems more broadly? This study aims to tackle these key questions for two Colorado River sub-basin recovery programs (one in the Upper Basin and one in the Lower Basin) through utilization of different frameworks and methodologies for each. Organizational resilience to institutional and biophysical disturbances varies, with the Upper Basin program being more resilient than the Lower Basin program. Ecological resilience as measured by beta diversity (for the Upper Basin) was a factor of the level of hydrological and technological interventions rather than an occurrence of the natural flow regime. This points to the fact that in a highly-dampened and managed system like the Colorado River, the dampened flow regime alone is not a significant factor in maintaining community diversity and ecological health. A broad-scale social-ecological analysis supports the finding that the natural feedback between social and ecological elements is broken and recovery efforts are more an attempt at resuscitating the river system to maintain a semblance of historic levels of fish populations and aquatic processes. Adaptive management pathways for the future need to address and build pathways to transformability into recovery planning to achieve resilience for the river system.
