Which one of the following regarding Johad is correct? Choose the correct option.

  1. A.It pumps groundwater into nearby wells.
  2. B.Stores water from rivers.
  3. C.It is a community based rain water harvesting system.
  4. D.It filters impurities from water.

Correct answer

C. It is a community based rain water harvesting system.

Explanation

The correct answer is C, It is a community based rain water harvesting system. A johad is a small crescent-shaped earthen dam that villagers build together to catch and store rainwater. It is used mainly in Rajasthan and Haryana, where rain is scarce and falls in only a few months of the year. The water held behind the bund is used for cattle and farming, and much of it soaks into the ground, refilling wells and raising the water table. In Alwar district of Rajasthan, villagers working with the Tarun Bharat Sangh built many johads, and the Arvari river, which had dried up, began to flow again. A is wrong because a johad does not pump groundwater; it helps to recharge it. B is wrong because it collects rainwater running off the land, not water drawn from rivers. D is wrong because a johad is a storage structure, not a water filter. Exam tip: johad, Rajasthan and Haryana; kul, western Himalayas; bamboo drip irrigation, Meghalaya; zing, Ladakh.
