Shortage of water is called the scarcity of water. It is due to the less rainfall or occurs in the drought prone area.
Causes of water scarcity are :
(i) India is the second largest populated country in the world and for more population, we need more water to produce crops or other domestic use.
(ii) Excessive use of water in the industries for producing more hydro electricity.
(iii) Over exploitation of water in urban areas leads to the water scarcity in India.
