Micro-Irrigation: Drip & Sprinkler Systems
How watering a plant drop by drop uses less than half the water that flooding a field wastes
Imagine two completely different ways to water a crop. The first is flooding the entire field with water and letting it soak in wherever gravity takes it. This wastes enormous amounts of water to evaporation and runoff. The second is delivering water in small, precise amounts directly to each plant's roots, through a network of tubes and small nozzles called emitters.
Micro-irrigation is this second, more precise method. It covers two main types: drip irrigation, which delivers water drop by drop, and sprinkler systems, which spray water in a controlled pattern.
The water savings are genuinely significant: typically 30% to 50% less water used than traditional flood irrigation, for the same crop yield. This matters a great deal, because farming already uses the overwhelming majority of India's total freshwater supply. This means adopting micro-irrigation affects not just one farm's productivity, but India's broader water security as well.
The government supports this technology through a part of a bigger scheme called PMKSY (Pradhan Mantri Krishi Sinchayee Yojana), specifically its 'Per Drop More Crop' component. This provides subsidies to help cover the cost of installing drip and sprinkler systems, which are genuinely more expensive upfront than simple flood irrigation. This kind of targeted financial help is needed to make the technology's long-term water and cost savings accessible to farmers who could not otherwise afford the initial investment.
Micro-irrigation adoption connects directly to the PM-KUSUM solar pump programme, explained elsewhere on this site. Solar-powered pumps paired with drip irrigation form a genuinely complete, efficient package: water delivered exactly where it is needed, powered by a low-cost, reliable energy source. This is the kind of combined infrastructure upgrade that improves both water and energy efficiency at the same time, instead of solving just one problem at a time.
