eighty-nine percent of aquaculture production takes place in asia most of it in the tropical and subtropical belts (sofia 2016)…and in freshwater
Aquaculture not only relevant for direct food production but also for livelihoods
Fish farming directly employs 18 million worldwide In 2010 FAO had estimated that 117 million were dependent on aquaculture through its multiplier effects Specially relevant for women in postharvest

Drought and freshwater scarcity
Changes in ocean circulation
Changes in productivity of water bodies
Floods
Loss of coastal land and other ecosystems
Acidification of the seas

Changes in salinity and oxygen content
Algal blooms
Expansion and retraction of diseases and parasites
IMPACTS
Loss of production and infrastructure due to extreme events
Loss of production due to diseases, toxic algae and parasites
Shortage of wild seed
Limited/No access to water for farming
Limited access to feeds (both from marine and terrestrial sources)
Decrease productivity due to Longer term suboptimal farming conditions changes/ (>ToC, >%S,
