Last week I was attending a workshop organized by Rajasthan pollution Control Board and GIZ (new name of GTZ, Germany), on climate change.

Results presented by some leading researchers on climate change indicated that in Rajasthan, and in many other parts of India, temperature would rise by about 1.5 to 2 degrees, and there would be an increase in rainfall. What is more important is that this more rainfall is likely to be confined in smaller period of time. Which indicates that use of rainwater harvesting system is going to play an important role if we don't want to let this precious rain water go into the drain. 'don't let rain go into the drain', should be objective and slogan.
