CLIMATE CHANGE IN KERALA HARSHA BURNWAL
Situated on South western coastal region of India, with 700km long coastal line of Arabian Sea. High population density of 859/sq. km. (National average population density is 382/ sq. km.) Area 38864 sq. km., that is 1.18% of India

CLIMATE CHANGE AFFECTING TEMPERATURE According to Indian Meteorological Department, in last 43 years, the mean maximum temperature has risen about 0.8 ̊C, the minimum by 0.2 ̊ C and average by 0.6 ̊ C showing a clear upward trend in surface air temperature. Sunstroke events have increased which were uncommon in the past

CLIMATE CHANGE AFFECTING RAINFALL 2050 Projected PostMonsoon Rainfall
The detailed study has found that there is an increasing trend in post-monsoon rainfall over 40-50 years. It is also reported that Kerala has seen a cyclic trend in annual rainfall with a decreasing trend in South west monsoon rainfall and an increasing trend in postmonsoon rainfall.
KERALA FLOOD “the worst in 100 years” – 19 August 2018
The flood was a result of a strange monsoon phase that defied normal rainfall pattern.
Normal Trend
What happened in 2018 ?
On an average Kerala receives around 3,000 mm of rains annually, out of which the monsoon is responsible for 2,000 mm rainfall.
But by August 19, the state had already received 2,350 mm (over 700 mm in August alone) of rainfall despite the fact that third of the monsoon season was yet to come. According to IMD, Kerala received 2,346.6 mm of rainfall against a normal of 1,649.5 mm since the beginning of June – An excess of 42%
FUTURE RISK IN KERALA Topical cyclones and hurricanes, are expected to increase in strength by up to 10% with a 2 ̊C rise in global temperature. Under climate change the probability of such extreme rainfall is also predicted to grow by up to six-fold towards the end of the century. The rivers and drainage systems of Kerala have been unable to cope with large volumes of water and this has resulted in flash flooding. Much of the water would normally be slowed down by trees and other natural obstacles. Yet over the past 40 years Kerala has lost nearly half of its forest cover (9,000 sq. km.). This means that less rainfall is being intercepted, and more water is rapidly running into overflowing streams and rivers.
GOVERNMENT INITIATIVES (SAPCC) Afforestation programme – successful as several NGOs involved – Implementation of new commission reports to control development activities in Western Ghats Mountain Cleaning of neglected ponds and canals Rainwater harvesting mandatory for buildings > 1500 sq. ft. Schemes for groundwater recharge
Clean Environment Movement (no proper treatment mechanism)
FORESTRY
WATER
ENVIRONMENT
AGRICULTURE
TRANSPORT
ENERGY
Research on new crop varieties – tolerant to droughts and floods, design of new crop calendar
Pollution Control certificate mandatory for all vehicles Metro rail system panned for major cities
Subsidies for CFL, LED and Solar Energy, plan to make solar panel mandatory for buildings > 3000 sq. ft.
