Ways for conservation of water:

1. Use of modern irrigation methods such as drip or sprinkler irrigation.
2. Rational use of groundwater.

In traditional methods of rainwater harvesting, water is not only stored, but also used to recharge the groundwater.

These traditional water conservation methods had been developed in India considering the nature of rainfall in different regions, but the increasing population necessitated extension of agriculture, leading to deterio­ration of these traditional sources.
