Through this presentation children will also learn about some of the popular rainwater harvesting systems prevelant in the driest region of this country—Rajasthan, and surprisingly even the wettest—the Northeast. Why does a rain rich region like the Northeast need to harvest rainwater? Find out the answer to this and more through this PPT.
