Master of Arts / Department of Geography / Lisa M.B. Harrington / While environmental concerns have played a secondary role in dam removal rationales thus far, the Condit and Elwha removal projects could signal a change in governmental and public priorities in dam management in the United States (Born et al. 1998; Bednarek 2002). For this research, I compared two dam removal projects designed to restore native salmon runs in two rivers in Washington State: the Condit Dam on the White Salmon River and the Elwha and Glines Canyon Dams on the Elwha River. This thesis asks: given choices of preserving dams that produce clean electricity and the well-established lake-based habitats created by their reservoirs or re-establishing a free-flowing river to reestablish fish and wildlife populations, how are decisions made, and what does the process and outcome mean to local communities? Research interview data was used in combination with policy documents to answer three research questions: 1) What factors affect decision-makers’ and other stakeholders’ support for (or rejection of) dam removal? 2) How did stakeholders’ perceptions and opinions play a role in the decision-making process? and 3) What can we learn from problems and successes evident from the dam removal decision processes? The main factors influencing both the Condit Project and the Elwha Project were environmental (salmon restoration), political (meeting legislative requirements for fish passage), and economic (finding the least cost fish passage alternative). The primary motivation for both projects was salmon restoration via the provision of federally mandated fish passage. The possibility of regaining a valuable resource spurred Tribal, federal, and state agencies to advocate for the removal alternative. Dam owners in both cases desired the least cost option, resulting either in their consent to removal (Condit Project) or selling the dams and relinquishing responsibility to the federal government (Elwha Project). Both took over two decades to complete and were removed in 2011. Perceptions of the relative importance of removal/retention options and dissatisfaction with the decision-making process led to polarization of the communities affected by the dam removals and contributed to the 20+ year project timelines. In order to promote good will and understanding between decision makers and stakeholders, two lessons can be learned from the Condit and Elwha Projects: 1) actively seek to include both proponents and opponents in decision-making and 2) establish robust communication among stakeholders and decision makers. Additionally, preliminary evidence indicates that dam removal does result in movement of salmonids to river reaches that had been blocked by dams, and dam removal may also lead to unintended consequences related to local environmental quality and resource access, such as short term air quality concerns and longer term effects on groundwater availability.

Doctor of Philosophy / Department of Agricultural Economics / Jeffery R. Williams / The two topics addressed in this dissertation are both related to surface water quality. Reservoir sedimentation and water quality trading are examined from economic and environmental perspectives. Each topic and the resulting policy implications are relevant to stakeholders at the local, state, and federal levels. Reservoir sedimentation has been recognized as a major environmental, social, and economic issue in much of the Midwestern US. There is an effort to focus public and private funds to achieve the greatest return on the investment from soil erosion and sediment reduction strategies. How can physiographical and economic relationships within the watershed be quantified in such a way to provide insights into the selection of alternative management strategies? This study focuses on answering that question by integrating a physically-based watershed model with an economic analysis of alternative sedimentation reduction strategies for the case of Tuttle Creek Lake located in northeastern Kansas. Several key finding of this study are that both physiographical and economic factors must be considered for cost-effective conservation to occur. Considering these factors and targeting BMP implementation from 8 to 23 times more cost-effective than random implementation. If targeting cannot be done effectively or if “intangible” costs of BMP implementation are too large, dredging is likely to be more cost-effective. While this research compares the cost-effectiveness of various BMP implementation approaches in Kansas with dredging, the benefits associated with each of these strategies is not addressed. While there is substantial evidence that nonpoint sources have lower nutrient reduction costs than point sources, experience with water quality trading (WQT) reveals a common theme: little or no trading activity. These outcomes suggest the presence of obstacles to trading that were not recognized in the design of existing programs. To examine the ways that various market imperfections may impact the performance of a WQT market, an agent-based model is constructed, which simulates a hypothetical point-nonpoint market. This study first presents an overview of the concepts and simulation modeling technique used and then analyzes the effects of two prominent market impediments identified in the WQT literature: information levels and trading ratios. The results imply that if market designers feel that only a limited number of trades will be consummated, creating an institution that provides accessible information about buyers’ prices is preferred to providing information about sellers’ prices. Overall, more information is always better, but it becomes less important with higher trading ratios.

<p> </p> Nonpoint source (NPS) pollution refers to pollution entering receiving waterbodies from diffuse sources, and is one of the main causes of water pollution in the United States. Best management practices (BMPs) and low impact development (LID) strategies are water and land management practices geared at reducing the effect of NPS pollution. This research focused on residents in northwestern Indiana and assessed their interest in adopting BMPs and LID strategies across the urban-to-rural gradient. Resident groups of interest include medium/large-scale farmers, small-scale farmers, rural non-farming residents, suburban residents, and urban residents. Specifically, this research explored residents’ awareness of and attitudes towards water quality improvement practices, their likelihood of adopting these practices, and factors that influence their likelihood of adoption. Data was collected through a household survey that was mailed to residents of Porter and LaPorte counties. In addition to survey questions measuring respondents’ awareness, attitudes, perceptions, likelihood of adoption, and demographics, the survey also contained an experimental component in the form of an information page. By using descriptive, bivariate and multivariate statistical procedures to analyze survey data, this research found that respondents generally reported high levels of awareness of and positive attitudes towards BMPs and LID strategies. Despite this, 41% of respondents reported a likelihood of adopting any water quality improvement practices. This research found that resident groups differed in their awareness of water quality improvement practices, as well as their descriptive and subjective norms associated with adopting these practices. Respondents valued improved environmental quality and reduced flash flood risk as benefits of adopting water quality improvement practices, and identified not knowing enough about specific conservation practices and concerns about how to install and maintain the practices as main barriers to adoption. Generally, respondents who were younger, perceived more problems with various potential water pollution sources, were more aware of water quality improvement practices, had more positive attitudes, had a stronger sense of personal responsibility, sought information in the past about water quality problems, or perceived stronger social expectations from peers (i.e., subjective norms) were more likely to be interested in adopting water quality improvement practices in the next year. The role of information was more ambiguous. While information about how to choose, install and maintain specific water quality improvement practices may be useful for residents, the information treatment about the responsibility of each resident group for NPS pollution did not seem to affect respondents’ likelihood of adoption. However, this research did find that respondents reacted differently to the information provided based on their initial self-reported likelihood of adoption prior to receiving any information. Based on these results, this research suggests strategies that may be used by public and private entities to motivate residents’ adoption of water quality improvement practices, including but not limited to: (1) developing education programs that highlight both the broader environmental quality benefits and geography-specific practical benefits of water quality improvement; (2) developing technical assistance programs that help residents identify appropriate conservation practices for their homes and properties and that facilitate installation and maintenance of such practices; (3) developing communication strategies to help residents establish a sense of self-responsibility and align their perceived water quality problems with their own actions; and, (4) developing outreach programs to help establish and facilitate descriptive and subjective norms in favor of adopting water quality improvement practices at the watershed scale. <br> Nonpoint source (NPS) pollution refers to pollution entering receiving waterbodies from diffuse sources, and is one of the main causes of water pollution in the United States.

abstract: Design is a fundamental human activity through which we attempt to navigate and manipulate the world around us for our survival, pleasure, and benefit. As human society has evolved, so too has the complexity and impact of our design activities on the environment. Now clearly intertwined as a complex social-ecological system at the global scale, we struggle in our ability to understand, design, implement, and manage solutions to complex global issues such as climate change, water scarcity, food security, and natural disasters. Some have asserted that this is because complex adaptive systems, like these, are moving targets that are only partially designed and partially emergent and self-organizing. Furthermore, these types of systems are difficult to understand and control due to the inherent dynamics of "wicked problems", such as: uncertainty, social dilemmas, inequities, and trade-offs involving multiple feedback loops that sometimes cause both the problems and their potential solutions to shift and evolve together. These problems do not, however, negate our collective need to effectively design, produce, and implement strategies that allow us to appropriate, distribute, manage and sustain the resources on which we depend. Design, however, is not well understood in the context of complex adaptive systems involving common-pool resources. In addition, the relationship between our attempts at control and performance at the system-level over time is not well understood either. This research contributes to our understanding of design in common-pool resource systems by using a multi-methods approach to investigate longitudinal data on an innovative participatory design intervention implemented in nineteen small-scale, farmer-managed irrigation systems in the Indrawati River Basin of Nepal over the last three decades. The intervention was intended as an experiment in using participatory planning, design and construction processes to increase food security and strengthen the self-sufficiency and self-governing capacity of resource user groups within the poorest district in Nepal. This work is the first time that theories of participatory design-processes have been empirically tested against longitudinal data on a number of small-scale, locally managed common-pool resource systems. It clarifies and helps to develop a theory of design in this setting for both scientific and practical purposes. / Dissertation/Thesis / Doctoral Dissertation Environmental Social Science 2018

The monitoring and assessment of prawn populations in New South Wales (NSW), Australia, has been identified as a continuing research priority by both the fishing industry and the fisheries managers. This dissertation presents a series of dynamic population models developed to evaluate the status of the eastern king prawn (Melicertus plebejus) and eastern school prawn (Metapenaeus macleayi) populations within NSW and to analyse the relative performance of a number of alternative management strategies involving the three fisheries that target these species. Monthly commercial prawn catch and effort data from 1984 to 2006 were used to calibrate the stock assessment models. Where possible, the results of previous research were used to develop the structure of the model and to provide estimates of biological parameters. A process of increasing model complexity, including the addition of physical processes, such as river discharge events and economic considerations, was undertaken in an attempt to develop the most appropriate model for the analysis of management strategies. The first model presented was used to undertake a single-species assessment of the eastern king prawn stock and was based on a delay-difference population model with four different representations of recruitment. This model was calibrated to observations using the Bayesian sampling/importance re-sampling method and used to test the effect of significant changes in the future catch on the stock. The second model presented is a size-based metapopulation model which incorporated the dynamics of school prawns over three habitats, being harvested by three different fishing methods. This model was used to test the effect of alternative climate variability scenarios on the stock. The third model presented is a multi-species, multi-fishery bio-economic model. This model was used to examine the impact of nine alternative economic scenarios, incorporating various combinations of input costs and product prices. The results from the use of these models indicated that neither of the prawn population appeared to be over-exploited. The analyses also indicated that none of the alternative management strategies were found to stand-out enough to justify a move away from the current management strategy of input controls and spatio-temporal closures, even under a range of future scenarios including climate change and large movements in input costs and product prices.

Doctor of Philosophy (PhD) / This thesis critically analyses collective action processes and outcomes in Community Forestry through the concept of embeddedness. This research focuses on the questions of when people cooperate, how and why collective action emerges and evolves, and what leads or does not lead to equitable outcomes. The thesis makes a fundamental distinction between equality and equity. The research focuses specifically on the Nepalese experience with Community Forestry (CF), which is regarded as one of the most progressive CF programs being implemented in one of the poorest countries in the world. The thesis adopts an integrated research approach involving multiple actors, scales and methods with a focus on local level CF processes and forest users. This study considers the Forest Users Group (FUG) as a unit for analysis. Field work was conducted in three FUGs from the mid-hill region of Nepal over seven months between August 2001 and February 2002. The field research moves downwards to the household level and upward to the district, national and international level actors. It employs a combination of the process analysis and actor oriented approach and qualitative and quantitative methods to understand how CF is being driven, who is driving it and why CF is advancing in a certain direction. The study shows that the emergence, evolution and outcomes of collective action in CF are complex and varied due to specific and changing socio-cultural, economic, political and ecological contexts. Without understanding the complexities, in which peoples’ motivation and collective action are embedded, we cannot explain the emergence and evolution of collective action in CF. This thesis challenges the rational choice tradition and some key points of Common Property Regimes (CPR) theory and highlights the concept of embeddedness in participatory natural resource management. The thesis highlights the problem of decentralised CF policy and the forest bureaucracy. Decentralisation universally imposes a formal democratic system based on equality without acknowledging unequal societies. In Nepal, there has been little reorganisation of the forest bureaucracy. Despite being an international model for community forestry, in Nepal the existing bureaucracy has been unable or unwilling to transfer knowledge to forest users. The thesis concludes by stating the need to avoid the pitfalls of some democratic principles associated with standardisation and formalism. This means transforming bureaucratic norms and ideology. Context is central for the sustainable and equitable management of natural resources. It must be further researched and applied in decision-making if CF is going to achieve its potential to improve the condition of forests and the welfare of rural people.

The purposes of this research were 1) to understand what stakeholders in one nature center are "thinking"about the focus of their center and the niche it occupies; 2) to characterize the role of one nature center in its local community; 3) to examine the nature center in terms of established characteristics of a "best" nature center; 4) to compare stakeholder perceptions with perceptions of directors of exemplar nature centers and environmental education organizations; and 5) to characterize visitor and member stakeholder perceptions and motivations in terms of the extrinsic value of ecosystem services, bioeconomics, versus the intrinsic value of nature, biophilia. This research was conducted utilizing case study methodology with mixed method data collection. Ijams Nature Center visitors and members were surveyed concerning the value of nature; structured interviews were administered to Ijams Nature Center employees, nationally recognized nature center and environmental organization directors. Visitors‘ perceptions of nature focused on the natural surroundings of the nature center, providing opportunities to watch wild animals, appreciate nature, and feel at peace. Nature center member perceptions of nature reflected the concepts of stewardship and advocacy fostered by the Center‘s conservation mission, education programs, and preservation activities. Participants shared common thematic concepts for the role of nature centers and the characteristics of a best nature center. A best nature center was characterized as a composite of factors, practices, and perspectives that merge to form a business plan reflective of best practice guidelines. Participants highlighted the unique quality of centers and the passion and vision that guides development and the roles played by nature centers in their local communities, as identified in this study, i.e., education, advocacy, and immediacy. Ijams Nature Center visitors and members valued nature differently in terms of bioeconomics and biophilia, but both groups rated the biophilic value of nature of greater importance, with differing constructs reflective of that value.

<p>By presenting case studies from the village of Mahenye in Zimbabwe and the five villages of the Okavango Community Trust in Botswana, the study looks beyond the objectives, discourse and contests of policy and undertakes an investigation of what actions rural people are undertaking inside the institutions established by policy makers, and of governance outcomes at the local level. These case studies reveal that unfettered devolution can lead to elite capture and the perpetuation of poverty / that rural communities themselves have agency and the ability to exercise it / and that there is limited and shrinking political space in both countries which is reducing opportunities for rural communities to engage with political processes. The Botswana case studies demonstrates that an imported and imposed devolutionary initiative which lacks links to higher levels of governance can reduce political space at local levels. The Zimbabwe case study demonstrates that political space may be more effectively created through decentralisation. The lesson drawn from these case studies is that institutional arrangements and roles should be determined by context specific issues and circumstances and move beyond the structural determinism that has characterized much of the CBNRM debate to date. The study concludes with policy recommendations. These include the need for recognition of the synergy between CBNRM and democratisation as mutually reinforcing processes and the need to be context-specific...</p>

Mid-way through George Eliot’s Middlemarch, the heroine of the novel develops a plan to move from her country estate in England’s Midlands to the northern industrial county of Yorkshire, where she intends to found a model factory town. Dorothea Brooke’s utopian fantasy of class relations, ultimately abandoned, hints at the broader regional and geospatial discourse at work in this canonical Victorian novel, but is as equally ignored by critics as by other characters in Eliot’s realist masterpiece. In Communities of Place, I explore a new current of scholarship in Victorian studies by examining the role that England’s historic and geographic regions played in the development of the novel. Scholars of British literature and history have long argued that Victorian national and cultural identity was largely forged and promulgated from England’s urban centers. Over the course of the nineteenth century, the center became synonymous with London and, in the national metropolitan imagination, counties outside of London seemingly became homogenized into peripheral, anti-modern spaces. The critical tradition reinforces this historical narrative by arguing that the rise of nationalism precludes the development of regionalism. Thus, theorists of British nationalism have glossed over England’s intranational identity and have directed attention beyond England’s borders, to France or Scotland, to analyze national identity within Great Britain as a whole. Scholars of intra-English culture, meanwhile, often narrowly focused on county histories and the working classes in isolation. Both types of studies effectively argue that the English middle class, and the middle-class Victorian novel, lack regional affiliation; as Raymond Williams argues, middle-class Victorians were “external” to regional life. With Communities of Place, I join a scholarly conversation that offers an alternative to these scholarly cul-de-sacs: a critically engaged and historically responsive account of English regionalism. My project demonstrates how the development of distinctive English regional cultures paralleled, and occasionally destabilized, the formation of English national identity in the Victorian period. Central to this project is my assertion that the English upper and middle classes, like the working classes, were in part defined by their regional affiliations. Communities of Place, then, offers a historically specific understanding of regionalism as an important structuring framework for the social, geographic, and environmental relations in post-Romantic English literature, by drawing attention to four formulations of English regionalism: the early-Victorian defenses of industrial Northern Englishness, mid-Victorian regional conceptions of mixed rural and factory spaces, the repurposing of non-industrial landscapes for leisure, and the late-century return to the materiality of countryside, now emptied of Romantic naturalism. In each chapter I study geographically-specific cultural regions, from Elizabeth Gaskell’s industrial Lancashire to Thomas Hardy’s rural Wessex, in order to explore more generally how local class relations, topography, and recreational activities helped to shape discrete notions of Englishness outside of London. This methodology offers a productive alternative to center/peripheral models for understanding relations within England. By focusing on the depiction of regional responses to topics of national discussion, ranging from industrialism to the rise of consumer culture, I show how these issues were negotiated by the middle classes Victorian literature. These responses influence contemporary discussions about regional authority over landscape policy, the cultural status of the vernacular, and the preservation of green spaces in the urban nation.

<p>Coastal plain ponds are an understudied and threatened wetland ecosystem with many unique environmental attributes. Research in these ponds can investigate species-environment relationships, while simultaneously providing ecosystem-specific information crucial to their continued conservation and management. This dissertation explores patterns in coastal plain pond vegetation composition and species-environment relationships across space, through time, and in the seed bank and standing vegetation.</p><p>In a two-year field study at 18 coastal plain ponds across the island of Martha's Vineyard, Massachusetts, I investigated species-environment relationships within and among ponds. I identified vegetation species presences and abundances within 1 m2 quadrats, which ran continuously along transects established perpendicular to the water's edge. Species data were analyzed against local and landscape-scale environmental data. I also conducted a one-year seed bank study in which sediments from four coastal plain ponds were incubated in growth chambers and composition was compared to the standing vegetation. One hundred and thirty-four plant species were identified during vegetation sampling and 38 species were identified from incubated sediments.</p><p>I found significant compositional change across space in response to environmental gradients, with patterns in species composition occurring at both local and landscape scales. Elevation was the only local factor strongly correlated with species composition. Significant landscape-scale environmental factors included surficial geology and pond water salinity. Species composition was significantly correlated with hydrologic regime in 2005 but not in 2006. Overall patterns in vegetation species composition and abundance were more closely related to landscape-scale environmental variables than to local environmental variables. </p><p>I also found that coastal plain ponds undergo significant compositional change from one year to the next. Interannual variability disproportionately affected certain ponds and quadrats more than others, highlighting patterns in the relationships between compositional change and environmental attributes. Specifically, ephemeral ponds, ponds located on the moraine, ponds with high specific conductance values, and quadrats located closer to the waterline exhibited greater compositional change from 2005 to 2006 than permanent ponds, ponds located on the outwash plain, ponds with low specific conductance values, and quadrats located further from the waterline. </p><p>Finally, I found that coastal plain ponds exhibit a low degree of similarity between composition in sediments and standing vegetation. More species were identified in the standing vegetation than in the seed bank, and in most cases average species richness per quadrat was higher in the standing vegetation than in the seed bank. Seed bank and standing vegetation samples from ponds with different surficial geology were compositionally distinct. Seed bank samples from permanent and ephemeral ponds were compositionally distinct whereas standing vegetation samples were not.</p> / Dissertation
