Water Resource Management

India has had a long tradition of building various structures to manage water resources. Irrigation systems were built as early as during the Mauryan Empire.

Benefits of Dams: At present, many multipurpose dam projects have been built in India. These dams serve many purposes. They prevent flood by checking the flow of water. The water from the dams is used through a system of canals to irrigate far flung areas. Dams are also used for electricity generation. Moreover, drinking water is also supplied from the dams.

Harms of Dams: But dams have caused large scale displacement of people. Additionally, a vast tract of land gets submerged in the catchment area of dam. This results in large scale environmental consequences. Due to these reasons, many movement groups have begun protesting against building of large dams. Narmada Bachao Andolan is an example of such movements.

Rainwater Harvesting

Most of the rainwater just flows off without percolating down the ground. This can be prevented by using rainwater harvesting. Rainwater can be collected for future use or can be channelized to recharge groundwater. Rooftop rainwater harvesting is ideal to be applied at small scale. Many infrastructure projects; like Metro rail and flyovers have also started making provisions for rainwater harvesting. Some traditional examples of rainwater harvesting structures are: kuls in Himachal, tankas and khadins in Rajasthan, ahir and pynes in Bihar, etc.
