Description
Moderate physical activity, such as walking and biking, positively affects physical and mental health. Outdoor thermal comfort is an important prerequisite for incentivizing an active lifestyle. Thus, extreme heat poses significant challenges for people who are outdoors by choice or necessity. The type and qualities of built infrastructure determine the intensity and duration of individual exposure to heat. As cities globally are shifting priorities towards non-motorized and public transit travel, more residents are expected to experience the city on their feet. Thus, physical conditions as well as psychological perception of the environment that affect thermal comfort will become paramount. Phoenix, Arizona, is used as a case study to examine the effectiveness of current public transit and street infrastructure to reduce heat exposure and affect the thermal comfort of walkers and public transit users.
The City of Phoenix has committed to public transit improvements in the Transportation 2050 plan and has recently adopted a Complete Streets Policy. Proposed changes include mobility improvements and creating a safe and comfortable environment for non-motorized road participants. To understand what kind of improvements would benefit thermal comfort the most, it is necessary to understand heat exposure at finer spatial scales, explore whether current bus shelter designs are adequate in mitigating heat-health effects, and comprehensively assess the impact of design on physical, psychological and behavioral aspects of thermal comfort. A study conducted at bus stops in one Phoenix neighborhood examined grey and green infrastructure types preferred for cooling and found relationships between perception of pleasantness and thermal sensation votes. Walking interviews conducted in another neighborhood event examined the applicability of a framework for walking behavior under the stress of heat, and how differences between the streets affected perceptions of the walkers. The interviews revealed that many of the structural themes from the framework of walking behavior were applicable, however, participants assessed the majority of the elements in their walk from a heat mitigation perspective. Finally, guiding questions for walkability in hot and arid climates were developed based on the literature review and results from the empirical studies. This dissertation contributes to filling the gap between walkability and outdoor thermal comfort, and presents methodology and findings that can be useful to address walkability and outdoor thermal comfort in the world’s hot cities as well as those in temperate climates that may face similar climate challenges in the future as the planet warms.

Description
Urban heat is a growing problem that impacts public health, water and energy use, and the economy and affects population subgroups differently. Exposure and sensitivity, two key factors in determining vulnerability, have been widely researched. This dissertation focuses on the adaptive capacity component of heat vulnerability at the individual, household, and community scale. Using a mixed methods approach and metropolitan Phoenix as a test site, I explored how vulnerable communities understand and adapt to increasing extreme urban heat to uncover adaptive capacity that is not being operationalized well through current heat vulnerability frameworks. Twenty-three open-ended interviews were conducted where residents were encouraged to tell their stories about past and present extreme heat adaptive capacity behaviors. A community-based participatory research project consisting of three workshops and demonstration projects was piloted in three underserved neighborhoods to address urban heat on a local scale and collaboratively create community heat action plans. Last, a practitioner stakeholder meeting was held to discuss how the heat action plans will be integrated into other community efforts. Using data from the interviews, workshops, and stakeholder meeting, social capital was examined in the context of urban heat. Although social capital has been measured in a multitude of ways to gauge social relationships, trust, and reciprocity within a community, it is situational and reflects a position within the formal and informal aspects of any issue. Three narratives emerged from the interviews illuminating differentiated capacities to cope with urban heat: heat is an inconvenience, heat is a manageable problem, and heat is a catastrophe. For each of these narratives, generic adaptive capacity is impacted differently by specific heat adaptive capacity. The heat action plan workshops generated hyper-local heat solutions that reflected the neighborhoods’ different identities. Community-based organizations were instrumental in the success of this program. Social capital indicators were developed specific to urban heat that rely on heavily on family and personal relationships, attitudes and beliefs, perceived support, network size and community engagement. This research highlights how extreme heat vulnerability may need to be rethought to capture adaptive capacity nuances and the dynamic structure of who is vulnerable under what circumstances.

Description
Raising future generations is a culturally diverse, universally technological human project. This research brought the everyday work of raising children into the domain of sustainability scholarship, by first proposing a model of childrearing as a globally distributed socio-technical system, and then exploring the model with participants in two nodes – an elementary and middle school, and a children’s museum. In the process, the research objective shifted towards using methods that were less academic and more relevant to childrearing agents. The focus on participatory survey data was abandoned, in favor of autoethnographic documentation of a long-term engagement with a third node of the system, a child welfare setting. This approach yielded unexpected findings that fit the proposed model, identified characteristics of a Zone of Mutual Oblivion (ZMO) that exists between childrearing and sustainability, and clarified ways in which people prioritize their own needs and responsibilities, the developmental needs of children, the potential needs and capacities of future generations, and the functional integrity of ecological systems.

Description
Human connection is fundamental for a shift toward sustainable societies. Small groups of people working in response to their unique conditions and environment can find joy in the co-creation of a shared existence. A collaborative network of related efforts can contribute to a broader understanding of resilience and adaptation, aiming toward a regenerative relationship with the Earth and all species. Such an approach ameliorates both pervasive loneliness and extreme inequity that have grown from modern consumerist individualism, through a strong focus on trust, respect and authenticity. I have created a structure to pursue these goals as an applied Sustainability researcher and artist. First, I present a tool that measures and guides community-based work to support the values of equity, justice, transformation and connection. I follow this with an in-depth process of qualitative inquiry grounded in an applied participatory design project to gain insight on the act of building connection across perceived divides. Finally, I share “The Building Community:” the group and process I formed with formerly homeless individuals who are co-designing a tiny home ecovillage of transitional supportive housing for homeless human beings in the Skid Row neighborhood of downtown Los Angeles. The Building Community method combines Council-style talking circles with elements of Action and Design research in which equal co-learners embark on a fun and challenging journey to nurture housing security, interconnectedness, and sustainability. The results of this research indicate an opportunity for community-based researchers to further incorporate support for the rights of nature, decolonization efforts and preservation of the commons into their projects. Flexible structure, consistency, balanced effort and shared decision making proved to build a strong foundation for group processes centered on trust. Finally, The Building Community showed that intimate local groups can produce abundant and creative sustainability solutions when partnered with academic guidance and resources. Sustainability scholars have the chance to balance power, amplify voices and make collective visions manifest if they immerse themselves in efforts on the ground.

Description
This dissertation combines three research projects to examine the people affecting and affected by urban environmental change across multiple scales of decision making. In the Phoenix Metropolitan area and the Colorado River Basin, I study the social influence around the implementation of water use innovations among city-level stakeholders (Chapter 2) and I emphasize that water insecurity still exists in wealthy cities (Chapter 3). In Chapter 4, I ultimately consider grassroots solutions for achieving resource security alongside positive social change in a historically underserved community. In this dissertation, I have conceptualized my research questions by envisioning urban change as an opportunity for actors, at multiple scales, to simultaneously reduce resource waste and promote positive social change.

Description
In this multi-media dissertation, water is used metaphorically to equate the process of learning with embracing change. Paradigm shifts needed for sustainability require transformative learning where one is open to being shaped by new knowledge and experience. Properties of water – such as molecular bonding and phase changes – uncover lessons for humans’ adaptability. Given that human bodies are comprised mostly of water – what implications exist for human capacity to similarly undergo continuous change? An arts- based research methodology is practiced to produce a four-chapter project. Artistic methods of data collection and communication retain subjective complexity of lived experiences central to learning processes. Each chapter is prepared for a target audience and addresses widening scales of creative learning for sustainability.
Chapter one is a narrative ethnography that focuses on a personal creative process for sustainability learning. Chapter two is a co- authored journal that covers creative learning tools and design principles for sustainable classrooms. Chapter three is an open-access and adaptive, online toolkit that shares creative methods to cultivate curiosity and critical contemplation. Chapter four is an interactive showcase event that explores how water can inform and inspire individual and collective learning for sustainability.
This four-chapter project addresses the power of creative learning for sustainability at the personal, familial, formal classroom, informal online learning community, and public scales. Arts-based methods harness aesthetic power, welcome subjective complexity, and allow multiple meanings to be interpreted from research results. This multi- media project stretches the conventional structure of sustainability dissertations. The bridge between the arts and sciences is strengthened as this project shows synergies between these two ways of knowing. This research invites what can be learned from the wisdom of water – to both change and be changed by circumstances.

Description
Sustainability research and action in communities should be holistic, integrating sociocultural, biogeophysical, and spiritual components and their temporal and spatial dynamics toward the aim of co-creating thriving living systems. Yet scientists and practitioners still struggle with such integration. Regenerative development (RD) offers a way forward. RD focuses on shifting the consciousness and thinking underlying (un)sustainability as well as their manifestation in the physical world, creating increasingly higher levels of health and vitality for all life across scales. However, tools are nascent and relatively insular. Until recently, no empirical scientific research studies had been published on RD processes and outcomes.
My dissertation fills this gap in three complementary studies. The first is an integrative review that contextualizes regenerative development within the fields of sustainability, sustainable design and development, and ecology by identifying its conceptual elements and introducing a regenerative landscape development paradigm. The second study integrates complex adaptive systems science, ecology, sustainability, and regenerative development to construct and pilot the first iteration of a holistic sustainable development evaluation tool—the Regenerative Development Evaluation Tool—in two river restoration projects. The third study builds upon the first two, integrating scientific knowledge with existing RD and sustainable community design and development practices and theory to construct and pilot a Regenerative Community Development (RCD) Framework. Results indicate that the RCD Framework and Tools, when used within a regenerative landscape development paradigm, can facilitate: (1) shifts in thinking and development and design outcomes to holistic and regenerative ones; (2) identification of areas where development and design projects can become more regenerative and ways to do so; and (3) identification of factors that potentially facilitate and impede RCD processes. Overall, this research provides a direction and tools for holistic sustainable development as well as foundational studies for further research.

Description
Prior to the COVID-19 global pandemic, ecotourism represented the tourism industry’s fastest growing segment with projections estimating that ecotourism would become the world’s largest tourism type by 2030. While the tourism industry will need several years to rebound, if historic trends tell us anything, it is that ecotourism will continue to represent a large portion of the overall industry and will continue to grow at a rate that outpaces all other tourism types. In theory, ecotourism promotes sustainable socioeconomic development while also minimizing negative environmental impacts. Unfortunately, research suggests that this is not always true, and many examples exist of ecotourism causing more harm than good. In order to combat these potential negative impacts, the ecotourism industry has become increasingly reliant on ecotourism certification programs to act as an assessment tool that identifies ecotourism’s best practitioners while minimizing false advertising present within the industry. Despite these beliefs in the efficacy of certification, there is a lack of empirical research to actually support certification as an effective assessment tool. Furthermore, little research has been conducted that assesses the impacts that certification itself has on ecotourism businesses (both certified and uncertified) and the local communities dependent on ecotourism.
My dissertation employs a mixed methods design and combines qualitative and quantitative research methods spanning multiple geographic scales to develop an understanding of certification programs as they exist today and to discern the impacts that certification itself may cause for all those either directly or indirectly involved in ecotourism. My findings ultimately suggest that certification reform is needed if certification programs are expected to be the assessment tool ecotourism experts claim them to be. Specifically, as certification exists presently, there is: no universal guideline or standard for existing certification programs to follow, a disconnect between the advertised benefits certification offers and the actual benefits received, and a lack of market penetration both amongst ecotourists and ecotourism businesses. Each of these must be addressed before certification can live up to its full potential. Furthermore, I found that certification may impact community socioeconomic dynamics, particularly by creating or exacerbating community wealth distribution.

Description
The International Energy Agency (IEA) anticipates the global energy demand to grow by more than 25% by 2040, requiring more than $2 trillion a year of investment in new energy supply (IEA, 2018). With power needs increasing as populations grow and climate extremes become more routine, power companies seek to continually increase capacity, improve efficiency, and provide resilience to the power grid, such that they can meet the energy needs of the societies they serve, often while trying to minimize their carbon emissions. Despite significant research dedicated to planning for industrial projects, including power generation projects as well as the pipeline projects that enable power generation and distribute power, there are still endemic cost overruns and schedule delays in large scale power generation projects. This research explores root causes of these seemingly systemic project performance issues that plague power generation projects. Specifically, this work analyzes approximately 770 power and pipeline projects and identifies how project performance indicators (i.e., cost and schedule performance) as well as planning indicators, compare in two regulatory environments, namely nonregulated and regulated markets. This contributes explicit understanding of the relationship between project performance and regulatory environment, both quantitatively and qualitatively, to the pipeline and power project planning and construction bodies of knowledge. Following an understanding of nonregulated versus regulated markets, this research takes a deeper dive into one highly-regulated power sector, the nuclear power sector, and explores root causes for cost overruns and schedule delays. This work leverages gray literature (i.e., newspaper articles) as sources, in order to analyze projects individually (most academic literature presents data about an aggregated set of projects) and understand the public perception of risks associated with such projects. This work contributes an understanding of the risks associated with nuclear power plant construction to the nuclear power plant construction body of knowledge. Ultimately, the findings from this research support improved planning for power and pipeline projects, in turn leading to more predictable projects, in terms of cost and schedule performance, regardless of regulatory environment. This enables power providers to meet the capacity demands of a growing population within budget and schedule.

Description
Universities and colleges in the United States (U.S.) are in a period of rapid transformation. Driven by the need for an educated workforce, higher education institutions are responding to rapid innovation, globalization, economic realities, and sociodemographic shifts. Simultaneously, extensive educational online networks connect millions of people worldwide enable learning and knowledge sharing beyond what society has experienced to date. In light of technological advancements, the preservation and presentation of certain ideals that undergird academia and the communication and application of knowledge are undergoing dramatic change. Within higher education, this is both a challenge and an opportunity to re-envision the commitment to educate the public. This research discusses potential forms of this redesign and how it can build upon and depart from previous iterations of higher education. How colleges and universities will adapt to become more relevant, engaging, and accessible is a pressing question that must be addressed.
Using case studies focused on creating sustainability education materials, this dissertation develops knowledge related to three interconnected areas of study that will contribute to redesigning higher education through participatory action research methodology. First, higher education has a civic responsibility to provide new ways of thinking, being, and doing globally and providing more access to education to broader society, especially through public research institutions. Second, with a vast array of available learning materials, higher education should invest in elegantly-designed experiences consisting of well-reasoned, meticulously-curated, and high-quality content that is aesthetically appealing, engaging, and accessible to a broad audience. Third, as universities transition from the gatekeepers of knowledge to the connectors of knowledge, they also need to ensure that a coherent mission is articulated and invested in by stakeholders to create an intentionally beneficial transformational effort. The transformation of higher education toward a more inclusive learning environment through new ways of thinking and elegantly-designed learning experiences will serve to improve our learning institutions. As part of the necessary core for an educated democracy, higher education institutions must strive to create a more equitable, inclusive, and diverse society.
