Per Drop More Crop: 115 Lakh Hectares under Micro-Irrigation
and India's Water-Use Efficiency Challenge
Why in News?
Per Drop More Crop has brought more than 115 lakh hectares under micro-irrigation as of July 2026, placing
water-use efficiency at the centre of agricultural policy.
Agriculture uses more than 80% of India's available water resources, while only about 50% of net sown
area has irrigation facilities; the combination of high water use and incomplete irrigation coverage makes
efficiency as important as creating new water supply.
PDMC is currently implemented under Pradhan Mantri Rashtriya Krishi Vikas Yojana; it was a component of
PMKSY from 2015-16 to 2021-22.
Micro-Irrigation: Data in Practice
NITI Aayog's 2020-21 review reported farmer-income gains of 10-69% and water-use-efficiency
improvements of 30-70% under micro-irrigation.
Economic Survey2020-21 reported water savings of 20-48%, energy savings of 10-17%, labour-cost
reductions of 30-40%, fertiliser savings of 11-19% and crop-yield gains of 20-38%.
Financial assistance is available for up to 5 hectares per beneficiary: 55% assistance for small and
marginal farmers and 45% for other farmers.
These figures show that micro-irrigation affects the water-energy-fertiliser nexus simultaneously, rather than
being only an irrigation technology.
Drip and Sprinkler Systems
Drip irrigation delivers water near the root zone through emitters, reducing evaporation and conveyance losses;
in-line systems suit regularly spaced crops while on-line emitters can suit uneven plant spacing.
Sprinkler systems distribute pressurised water through nozzles and are useful for many field crops, pulses, spices
and situations where land levelling is difficult.
Fertigation applies soluble fertilisers through irrigation water; combining precise water and nutrients can reduce
the 11-19% fertiliser losses reported in micro-irrigation assessments.
Efficiency gains depend on design, pressure, filtration and maintenance; clogged emitters or poorly designed
systems can erase theoretical savings.

Groundwater irrigation links farm water use with electricity demand because millions of pumps lift water from
aquifers.
Micro-irrigation's reported 10-17% energy savings can reduce both farmer costs and the fiscal burden where
agricultural electricity is subsidised.
In over-exploited aquifers, however, efficiency can create a rebound effect if saved water is used to expand
irrigated area; water accounting and crop planning remain necessary.
Solar pumps need similar safeguards: zero marginal electricity cost can encourage excessive pumping unless
paired with groundwater governance.
Climate Resilience
Heat waves and erratic rainfall increase crop water stress, making controlled irrigation more valuable during
critical growth stages.
Micro-irrigation cannot create water where aquifers and reservoirs are depleted; it must be combined with
watershed development, rainwater harvesting and aquifer recharge.
With nearly half of net sown area lacking irrigation facilities, rainfed agriculture remains highly exposed to
monsoon variability.
Precision irrigation is therefore an adaptation tool, but climate resilience also requires crop diversification and
drought-tolerant varieties.
Crop Choice and Virtual Water
Water-intensive crops in water-stressed regions can undermine gains from efficient irrigation.
Virtual water refers to water embedded in producing traded goods; exporting water-intensive crops from stressed
basins can indirectly export scarce water.
Policy should combine micro-irrigation incentives with agro-climatic crop planning and realistic signals about
groundwater scarcity.
Millets, pulses and oilseeds can have lower water requirements than paddy or sugarcane in many agro-ecological
settings, though crop suitability is location-specific.
Governance and DBT
PDMC uses digital implementation and Direct Benefit Transfer to improve transparency in assistance for irrigation
equipment.
DBT reduces intermediary layers but accurate land, bank and beneficiary records remain necessary to prevent
exclusion.
State implementation capacity determines vendor quality, installation verification and after-sales maintenance.
Outcome monitoring should measure actual water saved and yield gained, not only hectares covered.
Way Forward
Move from hectare-based targets to basin-level water productivity measured as output or income per unit of
water.
Prioritise the most water-stressed blocks and high-value crops where the 30-70% efficiency gains can
produce maximum benefit.
Combine PDMC with Soil Health Cards, weather advisories, groundwater monitoring and crop diversification.
Create repair and maintenance ecosystems so installed systems remain functional beyond the subsidy period.
Prelims Quick Revision
PDMC coverage: over 115 lakh hectares by July 2026.
Agriculture uses over 80% of available water resources; only about 50% of net sown area has irrigation
facilities.
Assistance: 55% for small/marginal farmers, 45% for others, up to 5 hectares.
NITI review: 30-70% water-use-efficiency improvement and 10-69% income gains.
Economic Survey: 20-48% water savings and 20-38% crop-yield gains.
Probable Mains Question
Micro-irrigation can address India's water-energy-fertiliser nexus, but technology alone cannot solve
agricultural water stress. Examine with data from Per Drop More Crop.
