Water-Smart Farming with Per Drop More Crop

India's journey toward water-smart agriculture reflects a profound recognition that water security is inseparable from food security and rural livelihoods. The Per Drop More Crop (PDMC) scheme, now a cornerstone of the restructured Pradhan Mantri Rashtriya Krishi Vikas Yojana (PM-RKVY) since 2022-23, represents the culmination of nearly two decades of policy evolution. It began as the Centrally Sponsored Scheme for Micro Irrigation in January 2006, upgraded to the National Mission on Micro Irrigation (NMMI) in 2010-11, then integrated into the National Mission on Sustainable Agriculture (NMSA) under the On Farm Water Management component in 2014-15, and later became the flagship component of Pradhan Mantri Krishi Sinchayee Yojana (PMKSY) from 2015-16 to 2021-22. This trajectory mirrors India's shifting governance philosophy — from isolated scheme-based interventions to integrated, outcome-oriented missions. The constitutional context is critical. Agriculture falls under the State List (Entry 14, List II, Seventh Schedule), while inter-state water disputes and regulation of inter-state rivers fall under the Union List (Entry 56). Water itself is a state subject, but the Centre's role in financing and guiding irrigation efficiency through centrally sponsored schemes like PDMC reflects cooperative federalism in action. The restructured PM-RKVY, with its flexible fund re-allocation across components, empowers states to tailor interventions to local agro-climatic realities — a significant governance innovation. Stakeholders span multiple levels: the Ministry of Agriculture & Farmers' Welfare (nodal ministry), state agriculture/horticulture departments (implementing agencies), NITI Aayog (monitoring and evaluation), financial institutions (credit linkage), and critically, 12.30 lakh farmers (20% women) who adopted micro-irrigation in 2025-26 alone. The scheme's direct benefit transfer (DBT) architecture and digital implementation have reduced leakages, aligning with the JAM trinity (Jan Dhan-Aadhaar-Mobile) governance model. Economically, the numbers are compelling. Central assistance of ₹8,123.24 crore in the last three years and ₹3,226.36 crore in 2025-26 for PDMC alone under PM-RKVY's ₹8,957.72 crore total allocation signal fiscal priority. NITI Aayog's 2020-21 evaluation and IIM Ahmedabad's 2023 six-state study validate outcomes: 20-48% water savings, 10-17% energy savings, 30-40% labour cost reduction, 11-19% fertilizer savings, 20-38% yield increase, and 10-69% income gains. For a country where 80% of water use is agricultural but only 50% of net sown area is irrigated, micro-irrigation's 115 lakh hectare coverage (8.11% of net sown area as of July 2026) is both progress and a reminder of the distance remaining. Socially, the scheme addresses groundwater stress — a crisis in Maharashtra, Karnataka, Andhra Pradesh, Tamil Nadu, Gujarat, and Rajasthan (top PDMC states in 2025-26). The new flexibility allowing states to exceed previous caps (20% general, 40% for NE/Himalayan states/UTs) on water storage/conservation activities like diggis and farm ponds under "Other Interventions" is a game-changer for rainfed areas. It enables conjunctive use of surface and groundwater, building climate resilience. Future implications are significant. With PM-RKVY merging nine schemes and adding an agri-startup accelerator fund, PDMC could integrate precision agriculture technologies (IoT sensors, AI-driven irrigation scheduling). The fertigation push aligns with nutrient-use efficiency goals under the Soil Health Card scheme. As India targets net-zero by 2070, micro-irrigation's energy savings (10-17%) contribute to agricultural decarbonization. The real test lies in scaling from 8.11% to meaningful coverage of the 140 million hectare net sown area — requiring sustained fiscal commitment, state capacity, and farmer awareness.
