Conservation of water
There is no change in the total quantity of water available on the earth. It remains the same. But the water useful for plants, animals and man is decreasing day by day. It is called scarcity of water.
What are the reasons for scarcity of water?
The main reasons for water scarcity
1. Population explosion
2. Uneven distribution of rainfall
3. Decline of ground watertable
4. Pollution of water
5. Careless use of water
We should take care to prevent scarcity of water. Otherwise,it is impossible for organisms to live on the earth. The only method of preventing scarcity of water is conservation of water. Saving water for the future generations by using water carefully and in a limited way is conservation of water.
Methods of water conservation:
Mainly, two methods can be followed for the conservation of water.
1. Water management
Water management consists of the following factors:
a. Bringing awareness about the bad effects of throwing wastes into the water bodies
b. Recycling of water by separating pollutants.
c. Minimizing the use of chemical fertilizers in agriculture. It reduces the pollution of underground water.
d. Controlling deforestation
e. Adopting drip irrigation and sprinkler irrigation in agriculture. By this way lesser amount of water can be used for the irrigation
2. Rainwater harvesting
Direct collection and use of rain water is called rainwater harvesting.
There are two types of rainwater harvesting.
a. Collecting water from where it falls.
(e.g): Collecting water from the roof tops of the houses or buildings (Roof water harvesting).
b. Collecting flowing rain water
(e.g): Collecting rainwater by constructing ponds with bund.
