Summary

In this chapter, we review the physical processes that affect the elevation of coastal settlements relative to the sea, and identify current and projected rates of change, describe the impacts of MSLR on coastal settlements and on small island states, provide rough estimates of the number of people exposed, identify options for in situ adaptation, describe common challenges in implementing planned relocations of communities at risk, with case studies from the Carteret Islands and Fiji, and conclude by reviewing the cascading risks faced in Bangladesh.
