Planned relocation may reduce communities’ future exposure to coastal inundation but effect varies with emission scenario and geography

E. R. Bower, S. Epifantseva, et al.

This study examines the effectiveness of relocating coastal communities as a strategy to combat climate change and reduce flooding risk. While most communities experienced reduced exposure, challenges remain, especially for origin sites and certain destination locations. Discover the findings from the research conducted by Erica R. Bower and colleagues.

Abstract

Planned, permanent relocation of coastal communities is a climate change adaptation strategy. This study assesses the effectiveness of relocation in reducing future coastal flooding risk for 17 global communities across three time points and three emissions scenarios. Most communities experienced exposure reduction, but the extent varied. Origin sites showed increasing inundation risk under high emissions, while nine destination sites also faced projected inundation. Small-island-to-small-island relocations showed less exposure reduction than other relocation types.
