Climate change poses new challenges to our existing systems for natural hazard risk management. To reduce risks from floods, droughts, and hurricanes, we have built levees, imposed water efficiency regulations, and reinforced infrastructure. However, rising seas and heavier rainfall events will increase the likelihood that today’s levees are overtopped. Shifting shorelines will threaten more houses and lives. Novel approaches to managing these risks may be needed to sustain safe, prosperous communities. This brief is based on the paper “Managed retreat as a response to natural hazard risk.”
