Causes of Scarcity of Water are:
1. Increase in Population:
Speedy increase in population means more use of water for various activities at domestic, agricultural and industrial levels.
2. Unequal Distribution:
Rain water is not equally distributed over the land. Some parts get heavy rains whereas others remain dry and become the Victims of drought and famine.
3. Dams and Anicuts:
For the use of water for industrial and agricultural purpose, Dams and Anicuts are made to collect water but due to lack of proper maintenance, the silt deposits reduce the water holding capacity of the dams and at some places a great havoc is caused due to breach in the dams.
4. Excess use of Water:
Water is not judiciously used for many day to day activities as brushing, flushing toilets, cleanliness, fountain and tub bath etc. A lot of water goes waste due to improper use of water.
5. Water Pollution:
Industrial wastes and domestic pollutants are thrown into the water resources and they make the water unfit for drinking and other purposes. With the cessation of use of water of such polluted resources, the water scarcity is caused.
6. Wastage of Rain Water:
The rain water remain unused and is not collected for use through different means. It flows into the sea. All these above factors besides the environmental factor as Global Warming are responsible for causing water scarcity.
