Description
Extreme hot-weather events have become life-threatening natural phenomena in many cities around the world, and the health impacts of excessive heat are expected to increase with climate change (Huang et al. 2011; Knowlton et al. 2007; Meehl and Tebaldi 2004; Patz 2005).

Extreme hot-weather events have become life-threatening natural phenomena in many cities around the world, and the health impacts of excessive heat are expected to increase with climate change (Huang et al. 2011; Knowlton et al. 2007; Meehl and Tebaldi 2004; Patz 2005). Heat waves will likely have the worst health impacts in urban areas, where large numbers of vulnerable people reside and where local-scale urban heat island effects (UHI) retard and reduce nighttime cooling. This dissertation presents three empirical case studies that were conducted to advance our understanding of human vulnerability to heat in coupled human-natural systems. Using vulnerability theory as a framework, I analyzed how various social and environmental components of a system interact to exacerbate or mitigate heat impacts on human health, with the goal of contributing to the conceptualization of human vulnerability to heat. The studies: 1) compared the relationship between temperature and health outcomes in Chicago and Phoenix; 2) compared a map derived from a theoretical generic index of vulnerability to heat with a map derived from actual heat-related hospitalizations in Phoenix; and 3) used geospatial information on health data at two areal units to identify the hot spots for two heat health outcomes in Phoenix. The results show a 10-degree Celsius difference in the threshold temperatures at which heat-stress calls in Phoenix and Chicago are likely to increase drastically, and that Chicago is likely to be more sensitive to climate change than Phoenix. I also found that heat-vulnerability indices are sensitive to scale, measurement, and context, and that cities will need to incorporate place-based factors to increase the usefulness of vulnerability indices and mapping to decision making. Finally, I found that identification of geographical hot-spot of heat-related illness depends on the type of data used, scale of measurement, and normalization procedures. I recommend using multiple datasets and different approaches to spatial analysis to overcome this limitation and help decision makers develop effective intervention strategies.

The lack of substantive, multi-dimensional perspectives on civic space planning and design has undermined the potential role of these valuable social and ecological amenities in advancing urban sustainability goals. Responding to these deficiencies, this dissertation utilized mixed quantitative and qualitative methods and synthesized multiple social and natural science perspectives to inform the development of progressive civic space planning and design, theory, and public policy aimed at improving the social, economic, and environmental health of cities. Using Phoenix, Arizona as a case study, the analysis was tailored to arid cities, yet the products and findings are flexible enough to be geographically customized to the social, environmental, built, and public policy goals of other urbanized regions. Organized into three articles, the first paper applies geospatial and statistical methods to analyze and classify urban parks in Phoenix based on multiple social, ecological, and built criteria, including landuse-land cover, `greenness,' and site amenities, as well as the socio- economic and built characteristics of park neighborhoods. The second article uses spatial empirical analysis to rezone the City of Phoenix following transect form-based code. The current park system was then assessed within this framework and recommendations are presented to inform the planning and design of civic spaces sensitive to their social and built context. The final paper culminates in the development of a planning tool and site design guidelines for civic space planning and design across the urban-to-natural gradient augmented with multiple ecosystem service considerations and tailored to desert cities.

Despite the arid climate of Maricopa County, Arizona, vector-borne diseases have presented significant health challenges to the residents and public health professionals of Maricopa County in the past, and will continue to do so in the foreseeable future. Currently, West Nile virus is the only mosquitoes-transmitted disease actively, and natively, transmitted throughout the state of Arizona. In an effort to gain a more complete understanding of the transmission dynamics of West Nile virus this thesis examines human, vector, and environment interactions as they exist within Maricopa County. Through ethnographic and geographic information systems research methods this thesis identifies 1) the individual factors that influence residents' knowledge and behaviors regarding mosquitoes, 2) the individual and regional factors that influence residents' knowledge of mosquito ecology and the spatial distribution of local mosquito populations, and 3) the environmental, demographic, and socioeconomic factors that influence mosquito abundance within Maricopa County. By identifying the factors that influence human-vector and vector-environment interactions, the results of this thesis may influence current and future educational and mosquito control efforts throughout Maricopa County.

Education for sustainable development (ESD) is an academic goal for many courses in higher learning. ESD encompasses a specific range of learning outcomes, competencies, skills and literacies that include and exceed the acquisition of content knowledge. Methods and case studies for measuring learning outcomes in ESD is absent from the literature. This case study of an undergraduate course in urban sustainability examines the processes, curriculum, pedagogies, and methods to explore whether or not learning outcomes in education for sustainable development are being reached. Observations of the course, and the statistical analysis of student surveys from course evaluations, are explored to help identify the relationships between learning outcomes in ESD and the processes of learning and teaching in the case study. Recommendations are made for applying the lessons of the case study to other courses, and for continuing further research in this area.

Despite the urgent need to reduce global greenhouse gas emissions (GHGs), there has been a lack of national climate action leadership in the United States. In this vacuum, the need for subnational action, particularly at the local level, has become essential. But cities only have the authority granted them by their state. Thus, many cities thus take climate action consistent, or in-sync, with their state. However, other cities take climate action inconsistent, or out-of-sync, with their state. This study examines this in-sync, out-of-sync phenomenon using a multilevel, multiple case study approach to determine the multilevel dynamics influencing whether a city is taking climate action. The study compares two states at opposite ends of the climate mitigation spectrum—Idaho, a state not taking any mitigation action, and Washington, a state taking aggressive mitigation action—and two cities within each of these states, with one city in-sync and the other out-of-sync with its state on climate action. The results show ideology/political affiliation as the most significant factor influencing state and city climate policy: progressive leaning cities/state are engaging in climate mitigation action; conservative leaning cities/state are not. This result was expected, but the study revealed many nuances that were not. For example, the strength of a city’s ideological leaning can overcome disabling state authority. Ideological leaning impacts whether non-state actors are a driver or barrier to climate action. Policy experimentation is found only in progressive cities. Co-benefits manifest in different ways, depending on ideological leaning and whether a city is in- or out-of-sync. And policy champion influence can be fully realized only with supportive elected leadership. This study highlights important interplays between drivers and barriers cities face in addressing climate change in a multilevel setting; how those interplays can help or hinder municipal climate action; and strategies cities employ to address challenges they face. The study findings thus contribute to the understanding of why and how cities take climate action, and how barriers to action can be overcome. This understanding is essential for providing a path forward on municipal climate action and accelerating the reduction of municipal GHG emissions.

ABSTRACT

Understanding complex and adaptive socio-ecological systems (SES) to deal with our most challenging and overlapping problems such as global climate change, biodiversity loss, and rising consumption rates requires sustainability theory that is commensurate with these problems’ size and complexity. The received United Nations-based sustainability framework aims to achieve a balance among three pillars—economics, environment, and social equity—for today and for future generations. Yet, despite applying this sustainability framework for over a quarter of a century, the Earth is less sustainable, not more. Theoretical trade-offs between environmental conservation and economic growth have often reinforced business-as-usual practices and educational paradigms, and emphasized economic values over ecological limits.

How can the principles of foundational naturalists help clarify, enhance, and advance sustainability discourse? I propose that the principles of Henry David Thoreau (1817-1862), Aldo Leopold (1887-1948), Rachel Carson (1907-1964), and Edward O. Wilson (1927-), express a worldview that captures and integrates a range and depth of historical, normative, economic, ecological, scientific, and social values for a viable and applicable discourse of sustainability.

This analytical study relies on (i.) textual analysis and interpretation of four key naturalists and humanists, (ii.) analysis of secondary sources that illuminate their proto- ecological and sustainability principles, and (iii.) interviews with leading sustainability scholars. Because these thinkers integrate science and ethics, natural history and philosophy, ecology and society, and environmental and economic problems within a holistic worldview, I call them systems naturalists. Their transdisciplinary worldview of one holistic system, with economics subordinated to environmental limits, links important values from the natural sciences and the humanities. The writings and examples of systems naturalists provide more robust historical sustainability principles that can help solve our most challenging SES problems by synthesizing a broad range of knowledge in the sciences, social sciences, and the humanities to inform sustainability paradigm, practices, and pedagogy.

The complexity and interconnectedness of sustainability issues has led to the joining of disciplines. This effort has been primarily within the sciences with minimal attention given to the relationship between science and art. The exclusion of art is problematic since sustainability challenges are not only scientific and technical; they are also cultural, so the arts, as shapers of culture, are critical components that warrant representation. In addition to contributing to the production of culture, arts have also been credited as catalysts for scientific breakthroughs; thus it stands to reason that understanding art-science integration will benefit sustainability’s focus on use-inspired basic research. I focus on placing art and science on equal footing to enhance understanding of how individual artists-scientists and collaborative artist-scientist teams creatively address sustainability challenges. In other words, I address the question “What does it take to develop high functioning artists-scientists or artist-scientist collaborations?”

To answer this question, I used a multipronged approach to triangulate a richer understanding of what art-science synthesis offers sustainability and how it functions. First, I performed an historical analysis of a maladapted wilderness aesthetic and turned to the work Aldo Leopold – an exemplar of an artist-scientist – for a new sustainability aesthetic. Then, I engaged in an individual contemporary art practice, culminating in a gallery exhibit, which displayed ecologically-informed work from a three year study of my backyard. Finally, I conducted small group research of artist-scientist teams tasked with developing interpretive signage for the Tres Rios wetland site. For this final element, I collected survey, wearable sensor, and ethnographic data.

Through this composite research, I found that successful art-science practices require significant energy and time investment. Although art-science is most intensive in an individual practice where the person must become “fluent” in two disciplines, it is still challenging in a group setting where members must become “conversational” in each other’s work. However, successful art-science syntheses appear to result in improved communication skills, better problem articulation, more creative problem solving, and the questioning of personal and disciplinary mental models. Thus, the outcomes of such syntheses warrant the effort required at both the individual and collaborative level.

It is widely recognized that, compared to others, minority and low-income populations are more exposed to environmental burdens and unwanted land uses like waste facilities. To prevent these injustices, cities and industry need to recognize these potential problems in the siting process and work to address them. I studied Phoenix, AZ, which has historically suffered from environmental justice issues. I examined whether Phoenix considered environmental justice concerns when siting their newest landfill (SR-85) and transfer station (North Gateway Transfer Station). Additionally, I assessed current views on sustainability from members of the Phoenix Transportation and Infrastructure Subcommittee and of decision-makers in the Public Works Department and Solid Waste Division. Using a mixed methods approach consisting of interviews, document analysis, and a demographic assessment of census tracts, I addressed two main research questions:

1. Do the distributions and siting processes of environmental burdens from SR-85 and North Gateway Transfer Station constitute a case of environmental injustice according to commonly held definitions?

2. Do current Solid Waste and council members on the Transportation and Infrastructure subcommittee consider environmental justice, defined as stakeholder engagement, to be a part of sustainability?

The results show that the distribution and siting processes of environmental burdens from these facilities may constitute a case of environmental injustice. While city officials do involve stakeholders in siting decisions, the effects of this involvement is unclear. An analysis of long-term demographic data, however, revealed no significant racial, ethnic, or economic effects due to the locations of the SR-85 and North Gateway Transfer Station.

Interviews with current members of the Transportation and Infrastructure Subcommittee, Public Works Department, and Solid Waste Division indicated that Phoenix’s decision-makers don’t consider environmental justice as part of sustainability. However, they seem to consider stakeholder engagement as important for decision-making.

To help mitigate future injustices, Phoenix needs buffer zone policies for waste facilities and stakeholder engagement policies for decision-making to ensure the public is engaged appropriately in all circumstances. Enacting these policies will help Phoenix become both a more sustainable city and one in which stakeholders have the opportunity to provide feedback and are given decision-making power.

Atrial fibrillation (AF) is the most common abnormal heart rhythm, affecting

nearly 2% of the world’s population at a cost of $26 Billion in the United States annually, and incalculable costs worldwide. AF causes no symptoms for some people. However, others with AF experience uncomfortable symptoms including palpitations, breathlessness, dizziness, and fatigue. AF can severely diminish quality of life for both AF sufferers and their loved ones. Beyond uncomfortable symptoms, AF is also linked to congestive heart failure and stroke, both of which can cause premature death. Medications often fail to control AF, leading patients and healthcare providers to seek other cures, including catheter ablation. To date, catheter ablation has yielded uneven results, but garners much attention in research and innovation in pursuit of a cure for AF. This dissertation examines the historical development and contemporary practices of AF ablation to identify opportunities to improve the innovation system for the disease. First, I trace the history of AF and AF ablation knowledge from the 2nd century B.C.E. through the present. This historical look identifies patterns of knowledge co-development between science, technology, and technique, as well as publication patterns impacting knowledge dissemination. Second, I examine the current practices of AF ablation knowledge translation from the perspective of clinical practitioners to characterize the demand-side of knowledge translation in real-world practice. Demand-side knowledge translation occurs in nested patterns, and requires data, experience, and trust in order to incorporate knowledge into a practice paradigm. Third, I use social network mapping and analysis to represent the full AF ablation knowledge-practice system and identify

opportunities to modify research and innovation practice in AF ablation based on i

measures of centrality and power. Finally, I outline six linked recommendations using raw data capture during ablation procedures and open big data analytics, coupled with multi-stakeholder social networking approaches, to maximize innovation potential in AF ablation research and practice.

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.
