Such opportunities are not specifically defined at this stage but ability to benefit will depend on adaptive capacity. At present, higher risk/impact regions have been outlined (Handisyde et al., Asia is by far the major aquaculture producer, with large populations and production zones in low-lying areas, and is the most vulnerable region. Deltaic areas in Asia and elsewhere are also critical for agricultural livelihoods and food security, and the loss of agriculture productivity due to salination from sea level rise and seawater intrusion could have an important impact.
