"Artificial recharge without scientific site selection is a wasted investment." Discuss with reference to recent geospatial initiatives of the Ministry of Jal Shakti.

India uses only about 60% of its extractable groundwater nationally (2024 Dynamic Assessment) [2]. That average hides over-exploited blocks where pumping exceeds recharge. Recharge structures built on the wrong slope, aquifer or drainage line either stay dry or silt up. The statement therefore largely holds, but scientific siting is necessary rather than sufficient.

Why unscientific siting wastes investment

• Hydrogeological mismatch: how much a structure recharges depends on rainfall, aquifer condition, slope and drainage together. A check dam on a steep slope or over an already saturated aquifer adds little [1].
• Fiscal leakage: the Master Plan 2020 plans about 1.42 crore structures to capture 185 BCM of monsoon rain. It has no dedicated fund and works through MGNREGS/PMKSY convergence [3], so badly placed works waste scarce shared funds.
• Audit evidence: CAG Report No. 9 of 2021 found that recommended recharge sites were not tracked to see whether they were built [4].

Geospatial initiatives of the Ministry of Jal Shakti

• Punah Bharan (Oct 2026): built by BISAG-N with the National Water Mission. The app finds recharge zones within 3 km of the user and suggests suitable structures. The web portal gives village-level zonation maps [1].
• Multi-criteria GIS overlay: five layers are combined instead of relying on guesswork [1]:

Rainfall + GW level + GW yield + Slope + Drainage
          ↓ GIS overlay
Village ARS zonation map → structure suggestion (≤3 km)

• It applies the Master Plan's terrain-wise design at the scale of a single site. It also supports Jan Bhagidari (community participation) under JSA: Catch the Rain.

Limits: siting alone is not enough

• Demand side: free power and higher MSP for paddy and sugarcane drive over-pumping [5]. Water that is recharged is simply pumped out again.
• Maintenance: silt reduces how fast water soaks in. The CGWB manual treats operation and maintenance as integral to recharge [6], yet convergence funds pay for building, not desilting.
• Federal gap: water is a State subject, so regulating extraction depends on State laws [4].

Scientific siting turns recharge from guesswork into a planned investment, and Punah Bharan supplies the tool. To make it pay off, each app suggestion should be geotagged against the MGNREGS/JSA asset built on it, and desilting should be funded. It should also be paired with the demand-side Atal Bhujal Yojana, which the Standing Committee wants extended to all water-scarce States [5]. Managing supply and demand together can advance SDG 6 and secure groundwater for future generations.
