Climate change will alter many ecosystem services provided by marine systems , but impacts to human communities will depend on people's overall vulnerability, which is strongly influenced by local context and development pathways . Catch composition and diversity of regional fisheries will change , and fishers who are able to move, diversify and leverage technology to sustain harvests decrease their own vulnerability . Management that eliminates overfishing facilitates successful future adaptation of fisheries to climate change . Marine-dependent communities, including Indigenous Peoples and local peoples, will be at increased risk of losing cultural heritage and traditional seafood- sourced nutrition . Without adaptation, seafood- dependent people face increased risk of exposure to toxins, pathogens and contaminants , and coastal communities face increasing risk from salinisation of groundwater and soil . Early-warning systems and public education about environmental change, developed and implemented within the local and cultural context, can decrease those risks . Coastal development and management informed by sea level rise projections will reduce the number of people and amount of property at risk , but historical coastal development and policies impede change . Current financial flows are globally uneven and overall insufficient to meet the projected costs of climate impacts on coastal and marine social-ecological systems . Inclusive governance that  accommodates geographically shifting marine life,  financially supports needed human transformations,  provides effective public education and  incorporates scientific evidence, Indigenous knowledge and local knowledge to manage resources sustainably shows greatest promise for decreasing human vulnerability to all of these projected changes in ocean and coastal ecosystem services .
