Suggest measures to improve water storage and irrigation system to make its judicious use under depleting scenario.

In short

India can use water judiciously by storing more of the monsoon in dams, tanks and aquifers and by cutting losses through piped canals, drip irrigation, farmer-run outlets and water-wise crops. The 161 reservoirs the CWC monitors make up only about 71% of the 257.8 BCM of storage India has built (CWC, 2025).

Model answer

Ghissu Editorial · Verified 4 Oct 2026

Introduction
The 161 reservoirs the CWC monitors account for only about 71% of India's built storage capacity, which sedimentation keeps eroding (CWC, 2025), while groundwater in Punjab and Haryana is pumped faster than it recharges. Judicious use means storing more water and losing less of it.
Measures to Store More of the Monsoon
•

Finish and restore

AIBP completed 69 of 99 priority projects, adding 26.84 lakh hectares of potential (Jal Shakti, 2025), and DRIP desilts old dams.

•

Revive small storages

Mission Amrit Sarovar (2022) targets 75 water bodies per district, and Tarun Bharat Sangh's johads revived the Arvari river.

•

Bank water underground

The CGWB recharge master plan (2020) and Atal Bhujal Yojana's community water budgets turn runoff into recharge.

Measures to Cut Losses from Source to Root
•

Pipes and drip

Piped networks such as Karnataka's Ramthal project and drip under Per Drop More Crop lift application efficiency to about 90% from 35-40% under flooding.

•

Farmers run outlets

Andhra Pradesh's 1997 Act and Maharashtra's volumetric supply to Water Users' Associations ensure rationed, timely delivery.

•

Match crops to water

Haryana's Mera Pani Meri Virasat (2020) pays farmers to leave paddy.

Way Forward
•

Price power

Metered farm power and PM-KUSUM solar pumps curb over-pumping.

•

One water institution

The Mihir Shah Committee (2016) urged a National Water Commission uniting CWC and CGWB.

Conclusion
Storing every monsoon and losing nothing on the way to the root turns scarcity into managed sufficiency, securing farm incomes and SDG 6.4 for a climate-resilient agriculture.
