With the country facing a grave water crisis and lack of water conservation, the availability of potable water and ground water has decreased over the years which would result in severe situation in the country after a decade, said an activist for water conservation on the eve of World Water Day (March 22) observed to create awareness about water related issues and for action to deal with the global water crisis.

"By 2030, 40 percent of the total population in the country will not have drinking water if situation remains same," Jal Jan Jodo Abhiyan's national convenor Sanjay Singh told reporters, quoting a research published recently by the 2030 Water Resource Group (WRG).

"The ground water is depleting, the small tributaries have dried up to 90 percent and the flow of rivers has reduced by 60-65 percent. This will lead to a severe situation in the coming years reducing water availability to a great extent," he added.

He also said that the per capita demand has increased whereas the availability is very less. In fact, a report on ground water published by PRS Legislative Research --a non-governmental organisation -- says: "Due to increasing population, the national per capita annual availability of water has reduced by 15 percent from 2001 to 2011."It also said that India uses almost twice the amount of water to grow crops as compared to China and the US.

"The gap between the availability and demand is increasing at a greater pace. Cities like Bengaluru, Delhi, Mumbai and other metropolitan cities consume water in huge quantities due to changed lifestyle of people. This must be looked into," Singh told reporters.
