“Coastal Capital: Belize” addresses threats to Belize’s coastal ecosystems such as unchecked coastal and tourism development and overfishing – by assessing the contribution of reef- and mangrove-associated tourism, fisheries, and shoreline protection services to Belize’s economy. Our results were used to justify new fishing regulations, a successful damage claim against a ship that ran aground on the Belize Barrier Reef, and a ban on offshore oil drilling.
