Main Body

Indian Ocean Warming:

1Rise in sea surface temperature
2Increased heating above the average,
3changing general atmosphere circulation due to heat
4Shift in ITCZ due to heating

Effect on food security:

1Weakening of monsoon due to inadequately high pressure at Mascarene High
[heating of Indian Oceanlow pressureweak monsoon]
2Low fish catch due to change in habitat
3Increased occurrence of cyclones disrupting the crops on coastal plains.

low water for crops
9Reduction in ground water table
Measuresfollow landmark goals of India to reduce GHG:
build resilient infrastructure
Adopt water resistant crops
