Sea level rise and the salinization of freshwater ecosystems will have unprecedented negative consequences on coastal communities in the coming decades. Salinization is already transforming the coastal landscape in complex ways -- altering the biogeochemistry, the vegetation composition, and the overall resilience of coastal systems. The economic dependence of many coastal communities on these regions' natural resources only compounds the negative impacts from sea level rise. The continued ability of these systems to provide life-sustaining ecosystem benefits like food production, clean water, carbon sequestration, and storm surge is at risk. Driven by global climate change, sea level rise poses a complex problem; one that involves multiple spatial and temporal scales and complex multi-directional interactions between social and ecological systems. The benefits that humans derive from the landscape inextricably link climate change, social processes, and land change dynamics. And although recognized as an important process in land change studies, scientists struggle to incorporate human behavior and decision-making processes into models. This linkage is critical, particularly in the context of sea level rise because the adaptive decision-making in response to sea level rise threats will largely determine continued system resilience. The three research objectives in this dissertation were driven by the desire to explore linkages between spatial patterns of landscape change and the social processes driving change. In the first research study, I combined field data with repeat lidar surveys to map the extent and magnitude of coastal biomass change across the forest to marsh transition. Resultant maps showed highly heterogeneous patterns of change. In the second research study, these maps were then used to quantify the relative contributions of land-use and sea level rise drivers to coastal biomass decline. Land-use activities continue to be the dominant drivers of change, even in low-lying coastal regions exposed to sea level rise impacts. In the final research study, we examined the landscape-scale implications of potential future adaptation scenarios using socio-spatial factors derived from landscape patterns and empirically-grounded social science data on contingent adaptive behaviors. The goal of this dissertation was to quantify the biophysical changes resulting from sea level rise and land-use activities and explore potential synergies or trade-offs between adaptation and the continued persistence of ecosystem services.Subjects--Topical Terms:
