decrease by 5.7% + 4.1% and 15.5% + 8.5% under SSP1-2.6 and SSP5-8.5 respectively by 2080-2099 relative to 1995-2014 , affecting food provisioning, revenue value and distribution. Catch composition will change regionally, and the vulnerability of fishers will partially depend on their ability to move, diversify and leverage technology . Global marine aquaculture will decline under increasing temperature and acidification conditions by 2100, with potential short-term gains for finfish aquaculture in some temperate regions and overall negative impacts on bivalve aquaculture due to habitat reduction . Changes in precipitation, sea level rise, temperature and extreme events will negatively affect food provisioning from inland aquatic systems , which provide a significant source of livelihoods and food for direct human consumption, particularly in Asia and Africa.
