With plenty of rainfall, why India is on world's most water-stressed list

within India, all nine states and union territories that report the worst water stress lie in the Indo-Gangetic plain, which has a web of big and small rivers and lakes.

Of the 17 countries facing the highest level of water stress--where 80% of water available is used up annually--India receives the maximum annual rainfall, according to an IndiaSpend analysis of a new study by the international think-tank World Resource Institute (WRI).

All other countries on the list belong to the arid and semi-arid regions of Africa, the Middle East and South Asia, receive almost half of India’s annual rainfall and have fewer natural water sources.

Even within India, all nine states and union territories that report the worst water stress lie in the Indo-Gangetic plain, which has a web of big and small rivers and lakes.

Chandigarh tops this list, as per the WRI, followed by Haryana, Rajasthan, Uttar Pradesh, Punjab, Gujarat, Uttarakhand, Madhya Pradesh and Jammu and Kashmir.

Why is India water-stressed despite widespread rainfall and a large number of water sources? “Overexploitation and mismanagement of water is the reason for this water stress,” said Shashi Shekhar, former secretary, ministry of water resources and Ganga rejuvenation, and a senior fellow with WRI India.

Inefficient agriculture, that uses up to 80% of all water resources in the country, is one of the primary reasons for India’s water stress, said Shekhar. Groundwater extraction--which provides for 40% of the country’s water needs--is significantly more than recharge.

The 17 countries dealing with acute water stress are home to nearly a quarter of the world’s population (1.75 billion). India ranks 13th on the list but at 1.36 billion, its population is more than triple that of the aggregate of the other 16 countries grappling with a water crisis, the study said.

About 600 million Indians are dealing with high-to-extreme water stress wherein over 40% of the annually available surface water is used every year, according to a 2018 study by government think-tank Niti Aayog 2018, reported by IndiaSpend on June 25, 2018.
