Land Vulnerable to Wave Induced Erosion and Storm Damage - St. Lucia

The definition of “land vulnerable to wave-induced erosion and storm damage” is based on expected wave heights and storm surge associated with a 25-year storm event, adjusted to be precautionary in light of anticipated sea level rise and increased storm intensity associated with warming seas. Vulnerable lands are defined as any land area of 5m or less elevation, within one km of the coast, as well as all land immediately adjacent to the coast (as defined by the 25m grid cell adjacent to the sea). Just over 4% of land in St. Lucia was classified as vulnerable to wave-induced erosion and storm damage (about 24.5 sq km).
