Answer: ✓. In the semi - arid and arid region aap Rajasthan , particularly in Bikaner, phalodi and Barmer, almost all the houses traditionally had underground tanks or tanks for storing drinking water.

✓. The first spell of rain was usually not collected as this would clean the ropes and the pipes .
✓. The rainwater from the subsequent shower was then collected.
✓. In many parts of rural and urban India, roof top rainwater harvesting is being successfully adapted to store and conserve water.
✓. In Gendathur; a remote backward village in Mysuru, Karnataka, villages had installed, in their household's rooftop, rain water harvesting system to meet their water needs. nearly 200 households have install this system.
ii. Describe how modern adaptions of traditional rainwater harvesting methods are being carried out to conserve and store water.
Answer:- ✓ In hilly and mountainous region, people built diversion panels like the 'guls' and 'kuls' of the Western Himalayas for agriculture. 'rooftop rainwater harvesting' was commonly practiced store drinking water, particularly in Rajasthan.
✓ In arid and semi-arid regions, agricultural fields were converted into rain fed storage structures that allowed the water to stand and moisten the soil like the ' khadins' in Jaisalmer and 'Johads' in other parts of Rajasthan.
✓ In Gendathur; a remote backward village in Mysuru, Karnataka, villages had installed, in their household's rooftop, rain water harvesting system to meet their water needs. nearly 200 households have install this system.
