Evaluate how geospatial technologies can help close India's groundwater governance gap, given that water is a State subject.

Water is a State subject (Entry 17, List II). The Centre can supply data and plans, but control over pumping rests with the States. This leaves a governance gap. Nationally, extraction is 245.64 BCM against an extractable 406.19 BCM (about 60%), but that average hides over-exploited blocks [2]. Geospatial tools can narrow this gap. They cannot close it on their own.

How geospatial tools help

• Scientific siting: The Punah Bharan app, built by BISAG-N with the National Water Mission, overlays rainfall, groundwater level, yield, slope and drainage data. It suggests recharge structures within 3 km of the user and gives village-level zonation maps [1].
• Cooperative federalism: The Centre provides common maps. States and panchayats still decide what to build and where, so State powers stay intact.
• Convergence: The Master Plan for Artificial Recharge 2020 has no dedicated fund and works through MGNREGS and PMKSY [3]. Shared suitability maps help all these schemes target the same sites.
• Local targeting: Block-level maps show the stressed areas that the national average hides [2].

Limitations

• Only the supply side: Maps guide recharge, not extraction. The Standing Committee on Water Resources (2023) linked over-pumping to free power and higher MSP for paddy and sugarcane [4].
• Weak State laws: In 19 States, groundwater laws follow the 1970 model Bill (revised 2005) and lack implementation guidelines [4].
• No follow-through: The CAG (Report No. 9 of 2021) found that recommended recharge sites were not tracked. It also found poor upkeep of recharge structures in Gujarat and Haryana [5].
• Access and data: Poor connectivity and outdated data layers can limit use in remote villages.

Verdict and way forward

• Geotag each suggested site when MGNREGS or Jal Shakti Abhiyan builds on it, and check it after every monsoon [5].
• Pair recharge maps with Atal Bhujal Yojana's community water budgets. Extend Atal Bhujal to all water-scarce States, as the Committee recommended [4].
• Give the National Water Mission more funds and autonomy [4].

Overall, geospatial technology closes the knowledge gap well but closes the regulation gap only partly. It works best as a shared tool between the Centre and the States, combined with State control of extraction and community participation (Jan Bhagidari). Used this way, it can move India towards sustainable water use under SDG 6.4.
