Modern adaptations of traditional rainwater harvesting include:
(a) 'Rooftop rainwater harvesting' is practiced in semi-arid areas of Rajasthan to store drinking water.
(b) In hills and mountainous regions people build diversion channels like that in the Western Himalayas for agriculture.
(c) In arid and semi-arid regions, agricultural fields were converted into rain fed storage structures that allowed the water to stagnate and moisten the soil like the ‘Khadins’ in Jaisalmer and the ‘Johads’ in other parts of Rajasthan.
(d) In the flood plains of Bengal, people developed inundation channels to irrigate their fields.
(e) Bamboo drip irrigation system is also being used in Meghalaya and other states in the North-East of India.
