The seven countries participating in the Climate Change Adaptation in the Eastern Caribbean Fisheries Sector (CC4FISH) project in the Eastern Caribbean – Antigua and Barbuda, Dominica, Grenada, St. Kitts and Nevis, Saint Lucia, St. Vincent and the Grenadines, and Trinidad and Tobago – are highly dependent on the fisheries sector for food security, livelihoods and household income. The sector is expected to be severely impacted by climate change and variability through slow-onset changes as well as extreme weather events. Negative impacts from climate change that are already obvious in this region include coral bleaching, increasing frequency of high intensity storms and hurricanes, increased sea level, and sargassum influxes that are disrupting fishing operations, fish landings and fisher livelihoods. While many of the root causes for climate change and climate variability originate outside of the Caribbean, the consequences are expected to be severe for the region and for the fisheries sector in particular. Coastal communities and fisherfolk (men and women involved in all aspects of the sector) are considered to be particularly vulnerable to the impacts of climate change.
