Describe methods of water conservation in agriculture.

Explanation

Agricultural water is often lost due to leaks in canals, run off and evaporation. Some of the water conserving methods are:
* using lined or covered canals that reduce loss of water and evaporation.
* using improved techniques such as sprinklers and drip irrigation.
* encouraging the development of crops that require less water and are drought resistant.
* mulching of soil in vegetable cultivation and in horticulture.
