Abstract
In order to meet the demand for food from a growing global population, aquaculture production must be increased as capture fisheries have stagnated. Rapid population growth with competition for land and water could affect aquaculture production. Although aquaculture uses non-consumptive water, there are significant water footprints for aquaculture due to water lost and water required for fish-feed production. Moreover, climate change affects water availability and demand for aquaculture, and poses a further threat to global fish production. Nevertheless, the efficient use of blue water (surface and groundwater) and green water (rain) in inland, coastal, and marine aquaculture could make a significant contribution to global fish production and climate change adaptation. Sustainable intensification of freshwater aquaculture, mangrove restoration with brackish water fish production, and the expansion of mariculture could increase global fish production with adaptation to climate change. Institutional support with technical and financial assistance is needed to implement the proposed adaptat ion strategies.
