what is rainwater harvesting explain advantage of rainwater harvesting

Answer 1

rainwater harvesting is the process by which rain water is stored for different purposes. It is mainly done in desert areas as they have only 4 or 5 times rainfall in each year. The desert people have large underground tanks which help them to store water for the whole year. These tanks are very well maintained.

Answer 2

Collection of rainwater for future use is called rainwater harvesting. India has a long history of different rainwater harvesting structures; especially in the rain-deficient areas. For example; tankas and bawris had been in use in North-Western part of India; especially in Rajasthan.
