Rainwater Harvesting

Rainwater harvesting (RWH) is a simple method by which rainfall is collected for future usage. The collected rainwater may be stored, utilised in different ways or directly used for recharge purposes. With depleting groundwater levels and fluctuating climate conditions, RWH can go a long way to help mitigate these effects. Capturing the rainwater can help recharge local aquifers, reduce urban flooding and most importantly ensure water availability in water-scarce zones. Though the term seems to have picked up greater visibility in the last few years, it was, and is even today, a traditional practice followed in rural India. Some ancient rainwater harvesting methods followed in India include madakas, ahar pynes, surangas, taankas and many more.

This water conservation method can be easily practiced in individual homes, apartments, parks, offices and temples too, across the world. Farmers have recharged their dry borewells, created water banks in drought areas, greened their farms, increased sustainability of their water resources and even created a river. Technical know how for the rooftop RWH with direct storage can be availed for better implementation. RWH An effective method in water scarce times, it is also an easily doable practice. Practical advice is available in books written by Indukanth Ragade & Shree Padre, talks by Anupam Mishra and other easy to follow fun ways

Water management traditions in the central-western Himalayas : a study by People's Science Institute
The study reviews a variety of water harvesting structures that have evolved over the millennia in central western Himalayan states of Himachal Pradesh and Uttarakhand Posted on 22 May, 2009 03:53 PM

The report highlights how traditionally, local communities exercised rights of ownership, use and management over their natural resources in the Himalayan states. They devised a variety of management systems suited to their own specific situation. Sanskar (precepts and rites), sanskriti (culture and customary practices) and niti (state policy and administration) were the bases of water harvesting traditions and their longevity. Individual dharma and social customs were the necessary conditions for sustaining these traditions, while local autonomy in resource management was the critical sufficient condition.

Swadhyayee movement captures running away rainwater in Saurashtra
Extraction of groundwater coupled with severe drought led to a reactive response in people of Saurashtra to divert rainwater into their wells in a bid to "capture" water which was "running off" Posted on 14 May, 2009 03:07 PM

Saurashtra is the peripheral region along Coastal Gujarat. It is composed of a Central basaltic plateau that rises 100 to 200m above mean sea level with an average annual rainfall of about 600 mm. The rainfall is concentrated in a few days during which the incident rainfall leads to flashfloods draining into the sea.
