Watershed management emphasises scientific soil and waterconservation in order to increase the biomass production. The aim is todevelop primary resources of land and water, to produce secondaryresources of plants and animals for use in a manner which will not causeecological imbalance. Watershed management not only increases theproduction and income of the watershed community, but also mitigatesdroughts and floods and increases the life of the downstream dam andreservoirs. Various organisations have been working on rejuvenatingancient systems of water harvesting as an alternative to the mega-projectslike dams. These communities have used hundreds of indigenous watersaving methods to capture every trickle of water that had fallen on theirland; dug small pits and lakes, put in place simple watershed systems,built small earthen dams, constructed dykes, sand and limestonereservoirs, set up rooftop water-collecting units. This has rechargedgroundwater levels and even brought rivers back to life.Water harvesting is an age-old concept in India. Khadins, tanksand nadis in Rajasthan, bandharas and tals in Maharashtra, bundhisin Madhya Pradesh and Uttar Pradesh, ahars and pynes in Bihar,kulhs in Himachal Pradesh, ponds in the Kandi belt of Jammu region,and eris (tanks) in Tamil Nadu, surangams in Kerala, and kattas inKarnataka are some of the ancient water harvesting, including waterconveyance, structures still in use today (see Fig. 16.3 for anexample). Water harvesting techniques are highly locale specific andthe benefits are also localised. Giving people control over their localwater resources ensures that mismanagement and over-exploitationof these resources is reduced/removed.Make 10 questions from this paragraph.
