This report by the World Resources Institute establishes a tiered methodology to estimate the economic value of coral reefs in the Caribbean, focusing on three key services: tourism and recreation, fisheries, and shoreline protection. Applying this tool to Tobago and St. Lucia, the study finds that coral reef-associated tourism provides the highest economic impact, contributing approximately 15% of GDP in Tobago and 11% in St. Lucia. Shoreline protection is also highly valued, with annual potentially avoided damages estimated between US$18–33 million for Tobago and US$28–50 million for St. Lucia. While reef-associated fisheries have a smaller direct financial impact, they provide critical social safety nets and cultural value. The report argues that quantifying these benefits is essential for informed coastal management and policy decisions, particularly in the face of threats from overfishing, pollution, and climate change.
