Are sustainable livelihoods critical to the success of community-based marine protected areas?Three community-based marine protected areas (CBMPAs) in the Visayas, Philippines were analyzed based on how well they incorporated sustainable livelihood programs into their overall management and planning for those displaced by the CBMPA. Through reviewing management plans and reports, the CBMPAs were then assessed to see whether including alternative livelihoods in these three cases was correlated with greater overall success. Each CBMPA was scored based on their alternative livelihoods and overall success. Management stakeholder perception surveys were also conducted for two of the CBMPA sites studied. Apo Island Marine Reserve scored the highest for its criteria for sustainable livelihood development and criteria for success of a CBMPA. Alternatively, Lawi Marine Reserve scored equivalent to that of Balcon Marine Protected Area for its criteria for sustainable livelihood development, yet the lowest for its criteria for success of a CBMPA. The most successful CBMPA was Apo Island Marine Reserve due to the incorporation of human dimensions into their management planning that helped them create sustainable livelihood programs that increased the community's compliance with the rules and regulations of the CBMPA. In contrast, Balcon Marine Protected Area and Lawi Marine Reserve did not have sustainable livelihood programs in place and their success was far below that of Apo Island. Thus, the overall success of these CBMPAs appears to be strongly correlated with alternative livelihood programs, however further study is needed to determine if this correlation between alternative livelihoods and success is true for the majority of CBMPAs in the Philippines.
Toward Arctic transitions and sustainability: modeling risks and resilience across scales of governanceThe Arctic region has been the subject of international attention in recent years. The magnitude of impacts from global climate change, land-use change, and speculations about economic development and accessible polar shipping lanes have intensified this focus. As a result, the potential to manage complex ecological, social and political relationships in the context of changes, risks and opportunities is the focus of a large and growing body of research. This dissertation contributes to the expanding scholarship on managing Arctic social-ecological systems for resilience by answering the question: What conditions improve cross-scale learning and resilience in nested social-ecological systems experiencing rapid changes? Using the framework of social-ecological systems and the drivers of change that can transform fundamental relationships within, three studies profile the spatial and temporal dimensions of learning and risk perceptions that impact nested social systems. The first study presents a spatial and temporal analysis of scale- and level-specific processes that impact learning from risks. It draws on four cases to underscore the need for a plurality of risk assumptions in learning for resilience, and sums up essential resources needed to support key decision points for increasing resilience. Two additional studies present research conducted with northern Alaska communities and resource managers. In these studies, I analyzed the extent to which perceptions of risks scale horizontally (between same-level jurisdictions), and vertically (between levels in a dominant jurisdictional structure). These examples illustrate the need for innovative institutions to enhance cross-scale learning, and to balance global drivers of change with local socioeconomic, cultural, and ecological interests. Based on findings of the dissertation research I propose recommendations to optimize the tools and processes of complex decision making under uncertainty.
