Description
Consideration of both biological and human-use dynamics in coupled social-ecological systems is essential for the success of interventions such as marine reserves. As purely human institutions, marine reserves have no direct effects on ecological systems. Consequently, the success of a marine reserve depends on managers` ability to alter human behavior in the direction and magnitude that supports reserve objectives. Further, a marine reserve is just one component in a larger coupled social-ecological system. The social, economic, political, and biological landscape all determine the social acceptability of a reserve, conflicts that arise, how the reserve interacts with existing fisheries management, accuracy of reserve monitoring, and whether the reserve is ultimately able to meet conservation and fishery enhancement goals. Just as the social-ecological landscape is critical at all stages for marine reserve, from initial establishment to maintenance, the reserve in turn interacts with biological and human use dynamics beyond its borders. Those interactions can lead to the failure of a reserve to meet management goals, or compromise management goals outside the reserve. I use a bio-economic model of a fishery in a spatially patchy environment to demonstrate how the pre-reserve fisheries management strategy determines the pattern of fishing effort displacement once the reserve is established, and discuss the social, political, and biological consequences of different patterns for the reserve and the fishery. Using a stochastic bio-economic model, I demonstrate how biological and human use connectivity can confound the accurate detection of reserve effects by violating assumptions in the quasi-experimental framework. Finally, I examine data on recreational fishing site selection to investigate changes in response to the announcement of enforcement of a marine reserve in the Gulf of California, Mexico. I generate a scale of fines that would fully or partially protect the reserve, providing a data-driven way for managers to balance biological and socio-economic goals. I suggest that natural resource managers consider human use dynamics with the same frequency, rigor, and tools as they do biological stocks.

Description
South Mountain is the largest municipal park in the nation. It is a bundled amenity, providing a series of linked services to the surrounding communities. A dataset of 19,209 homes in 155 neighborhoods within three miles of the park was utilized in order to complete a hedonic estimation for two nearby urban villages, Ahwatukee Foothills and South Mountain Village. Measures of access include proximity to the park, trailhead access, and adjacency to the park. Two regressions were estimated, the first including lot characteristics and subdivision fixed effects and the second using the coefficients for each subdivision as the dependent variable. These estimates describe how the location of a house in a subdivision contributes to its conditional mean price. As a result they offer a direct basis for capturing amenities measured at the neighborhood scale on home values. Park proximity, trailhead access and adjacency were found to significantly influence the price of homes at the 5% confidence level in Ahwatukee, but not in South Mountain Village. The results of this study can be applied to issues of environmental justice and park access in determining which areas and attributes of the park are associated with a high premium. Though South Mountain was preserved some time ago, development and future preservation in the City of Phoenix can be informed by such studies.

Did the amount of media attention to the H1N1 flu or the information that the Centers for Disease Control (CDC) disseminates about the H1N1 flu, influence individuals' decisions to avoid public locations during the 2009-2010 H1N1 Influenza pandemic? I investigate this question using weekly-confirmed H1N1 cases from the CDC, the American Time Use Survey (ATUS), and the Google Trends weekly search volume index for certain key terms. I found that individuals did exhibit some avoidance behaviour during the flu pandemic in response to the CDC data, but not the measures of media attention. However, the magnitudes of these adjustments are small in comparison to other measures of avoidance behaviour, such as reduced time in public during extreme weather events.

Description
This research project is part of a larger study of green infrastructure in urban planning and sustainability initiatives in cities across the U.S. Within the past few decades, the topic of sustainability has been at the forefront of city planners’ minds as cities grow, there is new or redevelopment, and the threat of climate change and future climate variability increases. Green infrastructure is one increasingly popular urban sustainability strategy, which is widely promoted for its ability to provide multiple benefits. This multi-functionality translates into ecosystem services and possible disservices for a local community and the city as a whole. This research project examines 120 planning documents from 19 U.S. cities to examine whether the services cities say they expect green infrastructure to provide, or the rationale, match with the criteria used to determine where green infrastructure is sited. For this project, we ask: what are the rationales that cities provide for developing green infrastructure and what are the criteria cities are using to determine where to site it? We find that certain rationales, or benefits, are claimed without corresponding and specific siting criteria to substantiate how these benefits will be achieved, while other benefits, like those related to stormwater management, are prioritized over other potentially important benefits.

Description
This study estimates the capitalization effect of golf courses in Maricopa County using the hedonic pricing method. It draws upon a dataset of 574,989 residential transactions from 2000 to 2006 to examine how the aesthetic, non-golf benefits of golf courses capitalize across a gradient of proximity measures. The measures for amenity value extend beyond home adjacency and include considerations for homes within a range of discrete walkability buffers of golf courses. The models also distinguish between public and private golf courses as a proxy for the level of golf course access perceived by non-golfers. Unobserved spatial characteristics of the neighborhoods around golf courses are controlled for by increasing the extent of spatial fixed effects from city, to census tract, and finally to 2000 meter golf course ‘neighborhoods.’ The estimation results support two primary conclusions. First, golf course proximity is found to be highly valued for adjacent homes and homes up to 50 meters way from a course, still evident but minimal between 50 and 150 meters, and insignificant at all other distance ranges. Second, private golf courses do not command a higher proximity premia compared to public courses with the exception of homes within 25 to 50 meters of a course, indicating that the non-golf benefits of courses capitalize similarly, regardless of course type. The results of this study motivate further investigation into golf course features that signal access or add value to homes in the range of capitalization, particularly for near-adjacent homes between 50 and 150 meters thought previously not to capitalize.

Description
Global climate change, rising average temperatures, rising water levels, irregularities in climate and river regimes, and increasing anthropogenic disturbances pose a significant risk to the ecosystems of protected areas. Given that past conditions are different from future conditions, managing protected areas faces serious challenges. New management approaches and strategies are needed to overcome these challenges. Planners and academicians have established methodologies for assessing the quality of climate change adaptation and resilience plans. However, a similar plan quality evaluation that considers climate change adaptation for National Park General Management Plans has not been conducted. This study adapted that methodology for national park management plans and applied it to analyze National Park General Management Plans across nine United States climate regions. Furthermore, this thesis aims to address this gap by asking and answering the following question: How do existing management plans for national parks meet the principles identified for effective planning for climate change? In this study, national park management plans are evaluated according to 112 criteria across seven principles, allowing for direct comparison and conclusions on strengths and weaknesses. The study revealed the strengths and weaknesses of the plans. Plans generally have similar weak points and strong points. While some aspects, such as public participation and coordination, perform relatively well, there are critical shortcomings in articulating a vision for climate adaptation, addressing uncertainty, and developing detailed strategies and monitoring mechanisms. The study will contribute to a better understanding of how protected areas can prepare for climate change impacts.

Description
Traditional infrastructure design approaches were born with industrialization. During this time the relatively stable environments allowed infrastructure systems to reliably provide service with networks designed to precise parameters and organizations fixated on maximizing efficiency. Now, infrastructure systems face the challenge of operating in the Anthropocene, an era of complexity. The environments in which infrastructure systems operate are changing more rapidly than the technologies and governance systems of infrastructure. Infrastructure systems will need to be resilient to navigate stability and instability and avoid obsolescence. This dissertation addresses how infrastructure systems could be designed for the Anthropocene, assessing technologies able to operate with uncertainty, rethinking the principles of technology design, and restructuring infrastructure governance. Resilience, in engineering, has often been defined as resistance to known disturbances with a focus on infrastructure assets. Resilience, more broadly reviewed, includes resistance, adaptation, and transformation across physical and governance domains. This dissertation constructs a foundation for resilient infrastructure through an assessment of resilience paradigms in engineering, complexity and deep uncertainty (Chapter 2), ecology (Chapter 3), and organizational change and leadership (Chapter 4). The second chapter reconciles frameworks of complexity and deep uncertainty to help infrastructure managers navigate the instability infrastructure systems face, with a focus on climate change. The third chapter identifies competencies of resilience in infrastructure theory and practice and compares those competencies with ‘Life’s Principles’ in ecology, presenting opportunities for growth and innovation in infrastructure resilience and highlighting the need for satisficed (to satisfy and suffice) solutions. The fourth chapter navigates pressures of exploitation and exploration that infrastructure institutions face during periods of stability and instability, proposing leadership capabilities to enhance institutional resilience. Finally, the dissertation is concluded with a chapter synthesizing the previous chapters, providing guidance for alternative design approaches for advancing resilient infrastructure. Combined, the work challenges the basic mental models used by engineers when approaching infrastructure design and recommends new ways of doing and thinking for the accelerating and increasingly uncertain conditions of the future.

Description
Transit agencies are struggling to regain ridership lost during the pandemic. Research shows that riding transit was among the most feared activities during the pandemic due to people’s high perceived risk of infection. Transit agencies have responded by implementing a variety of pandemic-related safety measures in stations and vehicles, but there is little literature assessing how these safety measures affect passengers’ perception of safety. This study implements surveys, interviews, and observations in Berlin, Germany to assess how passengers’ demographic characteristics and experiences with safety measures are related to their perception of safety using transit. Females and older age groups were more likely to perceive transit as riskier than males and younger age groups. The results provide little evidence to suggest that safety measures have a significant impact on passengers’ perception of safety, however. If this result is supported by future research, it suggests that transit agency investments in pandemic safety measures may not help them to regain ridership.

Description
This paper addresses the issue of conservation funding in Arizona, particularly for the Arizona Game and Fish Department. This department is traditionally funded by the Pittman-Robertson act, which places excise taxes on hunting equipment to fund species conservation, and sales of hunting tags and licenses, but there is concern that these sources are unable to cover the increasing costs of climate change. A decrease in hunter participation and expenditures on hunting equipment also brings into question the stability of these revenue sources. This paper explains and analyzes four methods to supplement the department's funding to ensure adequate financial resources are available to conserve state wildlife and wildlife areas and draws conclusions about which method is best for the state of Arizona.

Description
The continued rise of temperatures and extreme heat events globally is contributing to increases in mortality and morbidity in every region of the world. Urban areas are experiencing the combined effects of anthropogenic climate change and the urban heat island effect, exacerbating the risks associated with heat for urban residents. In response, cities must make every effort to adapt, pursuing engagement in high-quality planning processes and implementing robust sets of strategies to mitigate and manage the heat. Cities are shaped by networks of plans, however, the process of systematically evaluating these plans has focused on individual plans or plan types when assessing their quality. This study combines qualitative plan quality evaluation and semi-structured interviews to assess how Vienna’s network of plans addresses heat. Two clear divides emerge when analyzing the plan network; direction-setting principles are included more often than others, and mitigation strategies are more prevalent than management strategies. These results, which are consistent across the broader plan quality evaluation literature, illuminate a clear path for Vienna to continuously improve their planning process and effectively respond to heat.
