Temperature rise to hit water, forest, health: Report

India`s key sectors like water, forest, health and agriculture will be affected due to increase in net temperature.

New Delhi: India`s key sectors like water, forest, health and agriculture will be affected in a major way due to the increase in net temperature by 1.7- 2.2 degree celsius in another 20 years in the four climate hotspots.

The "Climate Change and India: a 4x4 assessment" report, which was released today providing an assessment of impact of climate change in 2030, also predicts an increase in
precipitation (rain, snow and storm) in the eco-fragile areas of the Himalayas, North-east, Western Ghats and the coastaln region.

Prepared by India`s Network for Climate Change Assessment (INCCA), the report says "the net increase in annual temperatures in 2030 with respect to 1970s would range between 1.7 degree Celsius to 2.2 degree Celsius with extreme temperature increasing by 1 to 40 degree Celsius with maximum increase in coastal regions."

The maximum and minimum temperatures are also projected to increase in 2030s compared to 1970s while the extreme preciptation events are likely to increase by 5-10 days in all the four regions.

Similarly, as per report, all the regions are projected to experience an increase in precipitation in 2030s as against 1970s and the maximum increase will be in the Himalayan region while minimum in the North East.

With changes in key climate variables such as temperature and humidity, sea level along the Indian coast has been rising at the rate of 1.3mm/year and is likely to do so in consonance with the global sea level rise in the future, the report says.

Further projections indicate that the frequency of cyclones is likely to decrease in 2030s, with increase in cyclonic intensity.

On agriculture front, the report says irrigated rice in all the regions are likely to gain in yields marginally due to warming as compared to the rain-fed crop as the irrigated rice
tends to benefit from CO2 fertilization effect.

Speaking at a function after the report was released by Science and Technology Minister Kapil Sibal and economist M S Swaminathan, Environment Minister Jairam Ramesh said there was no country in the world that is as vulnerable to climate
change as India.

"I am glad that for the first time such a comprehensive assessment has been undertaken," he added.

This is the second report from the INCCA which had in May released the country`s greenhouse gas emission data for 2007, making India the first developed country to released update data on the emission.

The network launched last year has been visualised as a mechanism to evolve institutions as well as engage other agencies already working in the area of climate change.
