Question

What are the causes of depletion of water resources?

Answer 1

There are many causes like

1. Due to rise in population - As a result of increasing population, all the facilities such as houses, shops, roads, offices, pavements, etc. increase to fulfil the increasing demands. This, in turn, decreases the open area for seepage of water into the ground.

2. Increase in agriculture - India is an agricultural country and agriculture is impossible without water. The water for agriculture is mainly utilised from ground water, rain water and canal water. As there is no rainfall in many places, agriculture cannot be entirely depended on rain water. Also, canal water is available in a few places only. Therefore, ground water is the main source of water for agricultural activities and this causes depletion of water table.

3. Increase in industrialization - Most of the stages of manufacturing processes in industries require water. If the number of industries increases, then the water required by them will also increase. Therefore, increase of industries contributes to the depletion of water table.

4. Deforestation - Decrease in plants and trees leads to decrease in rain which depletes the underground water body.....

Answer 2

The main causes of Depletion of Water Resources are Deforestation , Pollution and Overusing of groundwater.

Explanation:

• The main cause for the decline of underground water is related to the rapid growth in population leading to loss of high levels of groundwater and unlimited withdrawal of groundwater for daily needs
• Deforestation generally decreases rainfall and has a direct impact on natural climate change, thereby increasing the global temperature in the area.
• Forests helps to transport large amount of water into the atmosphere through transpiration.
• When deforestation occurs, rainfall is decreased which results in less groundwater and permanent drying of rivers which are the source of fresh water.
• Water Pollution is also a cause for depletion in water resources, as there is less water available for drinking purpose.
