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). 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.

Description
The coastal fishing community of Barrington, Southwest Nova Scotia (SWNS), has depended on the resilience of ocean ecosystems and resource-based economic activities for centuries. But while many coastal fisheries have developed unique ways to govern their resources, global environmental and economic change presents new challenges. In this study, I examine the multi-species fishery of Barrington. My objective was to understand what makes the fishery and its governance system robust to economic and ecological change, what makes fishing households vulnerable, and how household vulnerability and system level robustness interact. I addressed these these questions by focusing on action arenas, their contexts, interactions and outcomes. I used a combination of case comparisons, ethnography, surveys, quantitative and qualitative analysis to understand what influences action arenas in Barrington, Southwest Nova Scotia (SWNS). I found that robustness of the fishery at the system level depended on the strength of feedback between the operational level, where resource users interact with the resource, and the collective-choice level, where agents develop rules to influence fishing behavior. Weak feedback in Barrington has precipitated governance mismatches. At the household level, accounts from harvesters, buyers and experts suggested that decision-making arenas lacked procedural justice. Households preferred individual strategies to acquire access to and exploit fisheries resources. But the transferability of quota and licenses has created divisions between haves and have-nots. Those who have lost their traditional access to other species, such as cod, halibut, and haddock, have become highly dependent on lobster. Based on regressions and multi-criteria decision analysis, I found that new entrants in the lobster fishery needed to maintain high effort and catches to service their debts. But harvesters who did not enter the race for higher catches were most sensitive to low demand and low prices for lobster. This study demonstrates the importance of combining multiple methods and theoretical approaches to avoid tunnel vision in fisheries policy.

Description
This is a study of the plight of smallholder agriculture in Northwest Costa Rica. More specifically, this is the story of 689 rice farms, of an average size of 7.2 hectares and totaling just less than 5,300 hectares within the largest agricultural irrigation system in Central America. I was able to define the physical bounds of this study quite clearly, but one would be mistaken to think that this simplicity transfers to a search for rural development solutions in this case. Those solutions lie in the national and international politics that appear to have allowed a select few to pick winners and losers in Costa Rican agriculture in the face of global changes. In this research, I found that water scarcity among smallholder farms between 2006 and 2013 was the product of the adaptations of other, more powerful actors in 2002 to threats of Costa Rica's ratification of the Central American Free Trade Agreement. I demonstrate how the adaptations of these more powerful actors produced new risks for others, and how this ultimately prevented the rural development program from meeting its development goals. I reflect on my case study to draw conclusions about the different ways risks may emerge in rural development programs of this type. Then, I focus on the household level and show that determinants of successful adaptation to one type of global change risk may make farmers more vulnerable to other types, creating a "catch-22" among vulnerable farmers adapting to multiple global change risks. Finally, I define adaptation limits in smallholder rice farming in Northwest Costa Rica. I show that the abandonment of livelihood security and well-being, and of the unique "parcelaro" identities of rice farmers in this region define adaptation limits in this context.

Description
The manner in which land and water are used and managed is a major influencing factor of global environmental change. Globally, modifications to the landscape have drastically transformed social and ecological communities. Land and water management practices also influences people's vulnerability to hazards. Other interrelated factors are compounding problems of environmental change as a result of land and water use changes. Such factors include climate change, sea level rise, the frequency and severity of hurricanes, and increased populations in coastal regions. The implication of global climate change for small islands and small island communities is especially troublesome. Socially, small islands have a limited resource base, deal with varying degrees of insularity, generally have little political power, and have limited economic opportunities. The physical attributes of small islands also increase their vulnerability to global climate change, including limited land area, limited fresh water supplies, and greater distances to resources. The focus of this research project is to document place-specific - and in this case island-specific - human-environmental interactions from a political ecology perspective as a means to address local concerns and possible consequences of global environmental change. The place in which these interactions are examined is the barrier island and village of Ocracoke, North Carolina. I focus on the specific historical-geography of land and water management on Ocracoke as a means to examine relationships between local human-environmental interactions and environmental change.

Description
An asset-based approach to vulnerability, as presented in Voices of the Poor: Can Anyone Hear Us? and World Development Report 2000/2001: Attacking Poverty, provides a possible theoretical framework for understanding vulnerability to human trafficking. Case studies, field studies and narratives of human trafficking provide evidence that the assets of victims of trafficking play a significant role in human trafficking. This appears to be true both with regard to how traffickers exploit victim assets and with regard to how successful human trafficking prevention efforts are implemented. By exploring and further establishing this connection, I hope to provide evidence that a model of human trafficking acquisition incorporating elements of victim assets and the assets of communities deserves field-testing. Such field-testing will hopefully confirm the deep connection between assets and human trafficking activity and establish the necessary connections anti-trafficking activists will need to create a predictive version of the model with regard to individual vulnerability to human trafficking. Lastly, I argue that, provided the connection between human trafficking vulnerability and victim asset levels holds, an asset-based approach provides a rhetorical framework to resist policies that compromise asset levels of particularly vulnerable populations.

Description
With the ongoing drought surpassing a decade in Arizona, scholars, water managers and decision-makers have heightened attention to the availability of water resources, especially in rapidly growing regions where demand may outgrow supplies or outpace the capacity of the community water systems. Community water system managing entities and the biophysical and social characteristics of a place mediate communities' vulnerability to hazards such as drought and long-term climate change. The arid southwestern Phoenix metropolitan area is illustrative of the challenges that developed urban areas in arid climates face globally as population growth and climate change stress already fragile human-environmental systems. This thesis reveals the factors abating and exacerbating differential community water system vulnerability to water scarcity in communities simultaneously facing drought and rapid peri-urban growth. Employing a grounded, qualitative comparative case study approach, this thesis explores the interaction of social, biophysical and institutional factors as they effect the exposure, sensitivity and adaptive capacity of community water systems in Cave Creek and Buckeye, Arizona. Buckeye, once a small agricultural town in the West Valley, is wholly dependent on groundwater and currently planning for massive development to accommodate 218,591 new residents by 2020. Amid desert hills and near Tonto National Forest in the North Valley, Cave Creek is an upscale residential community suffering frequent water outages due to aging infrastructure and lack of system redundancy. Analyzing interviews, media accounts and policy documents, a narrative was composed explaining how place based factors, nested within a regional institutional water management framework, impact short and long-term vulnerability. This research adds to the library of vulnerability assessments completed using Polsky et al.'s Vulnerability Scoping Diagram and serves a pragmatic need assisting in the development of decision making tools that better represent the drivers of placed based vulnerability in arid metropolitan regions.

Description
Climate change impacts are evident throughout the world, particularly in the low lying coastal areas. The multidimensional nature and cross-scale impacts of climate change require a concerted effort from different organizations operating at multiple levels of governance. The efficiency and effectiveness of the adaptation actions of these organizations rely on the problem framings, network structure, and power dynamics of the organizations and the challenges they encounter. Nevertheless, knowledge on how organizations within multi-level governance arrangements frame vulnerability, how the adaptation governance structure shapes their roles, how power dynamics affect the governance process, and how barriers emerge in adaptation governance as a result of multi-level interactions is limited. In this dissertation research, a multilevel governance perspective has been adopted to address these knowledge gaps through a case study of flood risk management in coastal Bangladesh. Key-informant interviews, systematic literature review, spatial multi-criteria decision analysis, social network analysis (SNA), and content analysis techniques have been used to collect and analyze data. This research finds that the organizations involved in adaptation governance generally have aligned framings of vulnerability, irrespective of the level at which they are operated, thus facilitating adaptation decision-making. However, this alignment raises concerns of a neglect of socio-economic aspects of vulnerability, potentially undermining adaptation initiatives. This study further finds that the adaptation governance process is elite-pluralistic in nature, but has a coexistence of top-down and bottom-up processes in different phases of adaptation actions. The analysis of power dynamics discloses the dominance of a few national level organizations in the adaptation governance process in Bangladesh. Lastly, four mechanisms have been found that can explain how organizational culture, practices, and preferences dictate the emergence of barriers in the adaptation governance process. This dissertation research overall advances our understanding on the significance of multilevel governance approach in climate change adaptation governance.

Vulnerability research is a fairly new field of study and has yet to be applied to fields such as improvisation or online content creation. Making vulnerability public in a way that necessitates improvisation is fundamental to YouTube content creation. This Creative Project focuses on drawing connections between Vulnerability and Improvisation as it relates to creating content for YouTube. I did this through creating my own content which consisted of four YouTube videos centering around the theme of embracing fear. I found that in order to create content, I had to practice vulnerability myself and embrace improvisation if I wished to communicate those same themes to my audience. This project revealed that there are many ways which this powerful vulnerability research is yet to be applied, specifically in the realm of vastly public arenas such as YouTube. This research shows that vulnerability is not only applicable to interpersonal relationships, but has the potential to influenced thousands when used in public spheres.

Description
Regardless of religious beliefs, all one has left when they leave this Earth is the meaning the individual has derived from building connections and relationships with other people. I propose whether or not one is able to reach his or her potential and the quality of life that follows is based inherently in the following question: How will you manifest your truth into reality, thus becoming the best at your profession or craft, and spreading your gifts to help the lives of others? The answer to this question, and ultimately the key to leading the best life available is in the equation: vulnerability through playfulness and connection instigates happiness, which results in spreading positivity and facilitating the ability to make fearless decisions that guides one's life as an artist or profession of one's choosing, leading one to their highest potential. This theory applies to everyone and does not discriminate. This is the beginning of a life-long exploration and discovery with these elements as I further my work as an artist, and I will explore these themes from my exposure to the Balinese people and culture, our theatre workshops and experiences there, and through additional inspiration and research. The workshop and clowning in Bali training helped form the theory I have proposed, and further introduced a different approach to acting that I utilize in my own work that incorporates taksu: an achievable state of being that is unanimously understood by the Balinese that influences and shapes how they approach life, work, and each other that I discuss more extensively in my work. I will continue to inquire about how one finds space for imagination and pursuit of taksu without traveling, although traveling is an amazing way to broaden one's scope of perspective. The combination of elements discussed and taksu help create a humanity that is more in touch with inner peace and happiness as a result of spreading both positivity and a positive mindset to others. This in turn, influences and shapes performance and how we approach the craft of acting, while creating emotional truth and integrity within one's craft.

Description
This paper is a personal exploration of vulnerability in the creative process – how to recognize it, articulate it, and make active decisions despite feeling vulnerable while engaging in the creative process. It is structured mirroring Brené Brown’s Rising Strong Process: The Reckoning, The Rumble, and The Revolution. The reckoning is a process of inquiry and discovery that propels me towards growth. It’s becoming mindful so I can recognize patterns and explore why I habitually act/think in particular ways. The rumble, to me, consists of the process anteceding the choice to grow and change after discovering new knowledge from the reckoning instead of ignoring facing these findings because they present fear, shame, and vulnerability. And the revolution is not only what I take away from the reckoning and rumble process but how it affects the way I interact with the world, how I am irrevocably changed as a result of the rising strong experience. My research established three things: First, that the ability to be vulnerable catalyzes growth and deeper connection. Second, that the creative process lends itself to living vulnerably. And third, people are often blinded by vulnerability, resulting in inactive decision making. The paper follows an investigation grounded in this research where I engage in the creative process to build a dance performance piece and journey for both others and myself. Topics such as shame, fear, vulnerability, engagement, active-decision making, and connection are explored. Ultimately, the reckoning illustrated to me that the hardest thing about recognizing my vulnerabilities is discovering my habitual patterns that hide them from me. The rumble taught me various lessons but ultimately showed me engaging with vulnerability is a process that includes a lot of time and challenges. And my revolution solidified my self-worth will only be destroyed if I choose not to live a vulnerable and capricious life.
