Across India, groundwater schemes are up, but surface water schemes are declining

Pune:
In 14 years (2001-02 to 2014-15), net irrigation in India increased just 20 per cent, with an alarming trend of massive groundwater extraction. Per data from the Ministry of Statistics and Programme Implementation, while 41 per cent of the net irrigated area in India got water from tube wells in 2001-02, tubewell irrigation increased to 46 per cent in 2014-15. Interestingly, during the same period, irrigation based on canal systems came down to 24 per cent from 27 per cent and well irrigation declined to 17 per cent from 21 per cent. Not surprisingly, groundwater schemes are increasing, but surface water schemes are declining across India.

Other sources of irrigation have increased from 8 per cent to 11 per cent while use of tank irrigation has witnessed a minor decline (from 4 per cent to 3 per cent).

As per a report by the Committee on Restructuring of Central Water Commission and the Central Ground Water Board, when the annual withdrawal rate of groundwater is compared with the annual recharge of groundwater the picture that emerges is “not very rosy”.

The withdrawal rate expressed as a percentage of the net ground water available per year (termed level of Ground water development) exceeds 100 per cent in some states and is far from satisfactory in other States. “A major contributor to this rapid depletion in water tables is the overwhelming dependence on deep drilling of groundwater through tube wells,” the report adds.
