Holiday Homework Class 8/CBSE/D.P.S Alld./2018-19

Answer 1

FOLLOWING ARE SOME WAYS FOR WATER MANAGEMENT AND CONSERVATION:-

1. Protection of Water from Pollution;If the total fresh water available on the earth remains pollution free, it is sufficient to meet the drinking water needs of the existing population of the world, unfortunately a large portion of fresh waterdoes not remain fit for use of the living world due to increasing economic activities, urbanization etc.


2.Redistribution of Water:
Water found on the surface of the earth is not equally distributed. Existing form of distribution also becomes a reason for the water crisis. Hence, by arranging supply of water from areas having lesser demand to the areas having greater demand, water crisis can be minimized. By construction of surface water reservoirs and storage of excess water in them, supply can be made to scarcity affected areas. This work can be accomplished by development of water reservoirs and canal network.

3.Rational Use of Groundwater:
Demand for groundwater goes on increasing in proportion to its available quantity due to which quantity of groundwater goes on decreasing. After exploitation of groundwater, its re-infiltration takes a very long time to complete.Hence, groundwater exploitation should be only in proportion to its recharging capacity. In India, the maximum groundwater is utilized for agriculture.

4.Use of Modern Irrigation Methods:
A large portion of water can be conserved by adoption of modern methods of irrigation. Irrigation consumes double the quantity of water in comparison to all otheruses. Sprinkler and drip irrigation methodssave 50 per cent water.

5. Increasing Forest Cover:
Forest cover will have to be developed on uncultivable waste lands and hilly slopes on a large scale. Since trees bear drought conditions for a long duration as compared to crops, hence trees are helpfulin reducing the demand for water along with recharging water sources.
