The impacts of climate change are increasingly severe and the need for action is more urgent than ever. Caribbean islands are among the world’s most vulnerable, with storm frequency and intensity, flooding, wind damage and sea level rise all predicted to worsen, increasing threats to hospitals, power plants, freshwater sources, roads, houses and schools. Island communities must work together to prepare for disasters caused by natural phenomenon and minimize the impacts they will endure. Evidence shows that key ecosystems, like coral reefs and mangroves, can help reduce these risks while enhancing sustainable economic development. Resilient Islands is a four-year initiative to prepare Caribbean islands to cope with the impacts of climate change by promoting the use of coastal habitats to reduce risks, and by helping governments, partners and communities implement sustainable development plans that prioritize nature. The Nature Conservancy (TNC) and the International Federation of the Red Cross and Red Crescent Societies (IFRC) will work with communities and agencies to design innovative tools, train leaders, and implement demonstration projects within vulnerable coastal communities in the Dominican Republic, Grenada, and Jamaica.
