Region wise Projection by IPCC
Glacier melt in the Himalayas is projected to increase flooding, and rock avalanches from destabilized slopes, and to affect water resources within the next two to three decades. This will be followed by decreased river flows as the glaciers recede.
Freshwater availability in Central, South, East and Southeast Asia, particularly in large river basins, is projected to decrease due to climate change which, along with population growth and increasing demand arising from higher standards of living, could adversely affect more than a billion people by the 2050s.
areas, especially heavily-populated mega-delta regions in South, East
and Southeast Asia, will be at greatest risk due to increased flooding
from the sea and, in some mega-deltas, flooding from the
It is projected that crop yields could increase up to 20% in East and Southeast Asia while they could decrease up to 30% in Central and South Asia by the mid-21st century..
morbidity and mortality due to diarrhoeal disease primarily associated
with floods and droughts are expected to rise in East, South and Southeast
Asia due to projected changes in the hydrological cycle associated
with global warming. Increases in coastal water temperature would
exacerbate the abundance and/or toxicity of cholera in South Asia.
