RESUMEN DEL REPORTE

Los daños causados ​​por los huracanes a los arrecifes de coral en 2017 aumentan el riesgo de inundaciones futuras en Puerto Rico y Florida

Coral reef restoration can yield significant flood reduction benefits. These natural defenses were damaged in the 2017 hurricanes; their recovery would reduce the risks of further storm damages to nature, people and property.

RESUMEN DEL REPORTE

Los beneficios sociales y económicos de la restauración de arrecifes de coral en Puerto Rico

PUNTOS CLAVE

La restauración de los arrecifes de coral puede producir beneficios significativos en la reducción de inundaciones. Estas defensas naturales sufrieron daños a causa de los huracanes de 2017; su recuperación reduciría riesgos adicionales a la naturaleza, las personas y propiedades causados por tormentas.

Report Summary

Future Flooding Impacts from Projected Coral Reef Degradation in Florida

Projected future degradation of reef natural infrastructure puts U.S. people and property at significant risk of future flooding.

Key Points

Future flooding on Florida’s reef-lined coasts would increase by 16% if present reef loss continues.

The significant flood risk consequences of damage to coral reefs from Hurricanes Irma and Maria clarify why the defense benefits from this natural infrastructure should be recovered, repaired and restored.

Maps for the southern part of the Florida coastline show the increase in annual coastal hazard risk due to damage by Hurricanes Irma and Maria.
