Rainwater harvesting system socially economically and envirroment explain
Answers
y rainwater harvesting, we can recharge ground water by capturing and storing rainwater by construction of check dams, percolating pits etc.
1. It is cheap and affordable method of conservation of water.
for example: Roof top rainwater harvesting technique which is increased nowadays because Common people can also afford it.
2. Rain water harvesting techniques are more environmental friendly as compared to multipurpose river project.
3. Rainwater harvesting reduces pressure on existing water resources.
4. people had in depth knowledge of rainfall regimes and soil types and developed a wide range of rain water harvesting techniques .For example, the hilly and mountains regions, people built diversion channels like "guts" or "kuls" of western himalayas for agriculture.
Even we can see rooftop harvesting is seen in Rajas than to store drinking water.
Even in Rajasthan agricultural lands in semi -arid region are converted into rain fed storage structures that allowed water to stand and moisten the soil .
5. The use of bamboo drip irrigation are :it prevents leakage, increases crop yield with less water and makes use of natural , local and inexpensive material.
