Total groundwater recharge was 437.6 billion cubic metres, as opposed to extraction of 239.16 bcm, says Ministry of Water Resources in its 2022 assessment report

Groundwater extraction in India saw an 18-year decline, according to an assessment by the Central Ground Water Board (CGWB) made public on Wednesday.

The total annual groundwater recharge for the entire country is 437.60 billion cubic metres (bcm) and annual groundwater extraction for the entire country is 239.16 bcm, according to the 2022 assessment report. Further, out of the total 7,089 assessment units in the country, 1,006 units have been categorised as “over-exploited” in the report.

By comparison, an assessment in 2020 found that the annual groundwater recharge was 436 bcm and extraction 245 bcm. In 2017, recharge was 432 bcm and extraction 249 bcm. The 2022 assessment suggests that groundwater extraction is the lowest since 2004, when it was 231 bcm.
