Florida Coral Reefs and Coastal Hazard Risk Reduction

Aerial imagery of a peninsula are marked to show different data about each island's coast.

Detailed Description

Rigorously Valuing the Role of Florida’s Coral Reefs in Coastal Hazard Risk Reduction

Estimated Annual Benefits

Maps of Florida showing the distribution of the value of averted direct building damages, indirect economic activity losses, and population annually protected from flooding by coral reefs. Results at 10 m2 resolution are aggregated into 2-km coastal sections.
