Question

7) write the 2 main causes of water scarcity. Describe 3 main adaptations of traditional rainwater harvesting methods being carried on to conserve and store water

Answer 1

One of the major cause of water shortage is pollution. Water is polluted when industrial wastes are deposited into water bodies. Moreover, Oil spillage can makes the water contaminated.Thus it cannot be used for drinking. The second is related to lack of watermanagement in some countries.

Rainwater harvesting means capturing rain when it falls. It is done to meet the increasing demand of water as also to recharge the ground water. People living in urban areas have realized the importance of traditional rainwater harvesting methods like the rooftop storing method. The level of underground water in most of the urban areas has gone down much because of the increasing population, industrialization etc.

In Gendathur village, Mysore, about 200 households have adopted the rooftoprainwater harvesting method, thereby making village rich in rainwater. The Tamil Nadu government has made it compulsory for all the houses to have rooftop rainwater harvesting structures.
