Question

write a note on the water resources of India

Answer 1

Dear student,

• India contributes to 4% of the world's water resources.
• India recieves water from annual rainfall and surface and groundwater sources but only 60% of the water from these sources is usable.
• Main surface sources are rivers, lakes, ponds and tanks in India. Peninsular rivers like Kaveri,Godavari,etc. have less annual water flow but their water is utilised.
• Ganga and Brahmaputra basins have 46% of the total renewable groundwater resources.
• Wells are mainly used to draw the groundwater and the groundwater utilisation is relatively higher in North Western and Southern parts of India.
• There are lagoons and backwaters due to the indented coastlines are of some states like Kerala, Odisha and West Bengal.
• Water is highly demanded for domestic, industrial and agricultural purposes in India. Thus, multipurpose dams and river valley projects like Sardar Sarovar, Bhakra Nangal, etc. are undertaken by the government.
