Abstract

Sea level rise (SLR) is believed to be the most dangerous impact of climate change in coastal regions. Adapting to its impacts has become imperative since SLR is now considered inevitable. Lack of local economic analysis of SLR impacts is one of the major obstacles impeding adaptation. To address this gap, this study employs a spatiotemporal approach to estimate the economic costs of future SLR as well as the benefits of coastal protection, a principal adaptation strategy, under four local SLR projection scenarios in the mainland Miami-Dade County, Florida. Our findings indicate that SLR impacts are nonlinear and coastal protection, while costly, can significantly reduce future potential losses. A novel spatial fishnet approach is also proposed to help local decision makers identify areas that should be prioritized for protection. Findings of this study aim to support local adaptation planning, and call for integrating adaptation for SLR and its uncertainties into local planning frameworks to achieve long-term sustainability and well-being of our precious coastal communities.
