Marine and coastal ecosystems in Asia are likely to be affected by sea-level rise and temperature increases (high confidence). Projected sea-level rise is very likely to result in significant losses of coastal ecosystems and a million or so people along the coasts of South and South-East Asia will likely be at risk from flooding (high confidence). Sea-water intrusion due to sea-level rise and declining river runoff is likely to increase the habitat of brackish water fisheries but coastal inundation is likely to seriously affect the aquaculture industry and infrastructure particularly in heavily-populated megadeltas (high confidence). Stability of wetlands, mangroves and coral reefs around Asia is likely to be increasingly threatened (high confidence).
Recent risk analysis of coral reef suggests that between 24%and 30% of the reefs in Asia are likely to be lost during the next 10 years and 30 years, respectively (medium confidence). Increases in endemic morbidity and mortality due to diarrhoeal
disease primarily associated with climate change are expected in South and South-East Asia (high confidence). Increases in coastal water temperature would exacerbate the abundance and/or toxicity of cholera in south Asia (high confidence). Natural habitats of vector-borne and water-borne diseases in
north Asia are likely to expand in the future (medium
confidence).
