List any four advantages of water harvesting.
Answer:
Four advantages of water harvesting:
- Water collected in ground does not evaporate, but spreads out to recharge wells and provides moisture for vegetation over a wide area.
- The groundwater is also relatively protected from contamination by human and animal waste.
- It provides year round supply of drinking water.
- It does not provide breeding grounds for mosquitoes like stagnant water collected in ponds or artificial lakes.
