CSA sub-regions are highly dependent on ocean and coastal ecosystems and, thus, vulnerable to climate change . Fisheries and aquaculture contribute significantly to food security and livelihoods by creating employment , income and economic growth for the region . More than 45% of the total fisheries in CSA are based on marine products . Peru, Chile, Argentina and Ecuador are among the 15 countries with the largest marine capture production worldwide , while more than 90% of the hydrological resources produced by aquaculture in CSA have a marine origin . There is high confidence about important current and future impacts of climate-change hazards in marine resources used by fisheries; however, there is low evidence regarding impacts on regional economies .
