Why micro-irrigation needs more than subsidies

India's water challenge is also an economic challenge. Severe El Nino conditions can weaken the monsoon, reduce agricultural output, fuel food inflation and impose cumulative economic losses approaching $1 tn (₹95.6 lakh cr) over time. In a country where agriculture consumes nearly 80% of available freshwater, climate adaptation is no longer just an environmental priority but an economic necessity.

Recognising this, GoI has approved a plan to bring another 100 lakh ha under micro-irrigation through the revamped PM Krishi Sinchayee Yojana (PMKSY). The target is timely. But achieving it will require more than expanding subsidies. It'll require solving India's biggest irrigation challenge, which is farmer adoption.

A recent Council for Social Development (CSD) study provides fresh evidence. Based on a survey of 500 farming households in the semi-arid districts of Nuh in Haryana and Alwar in Rajasthan, the study found that micro-irrigation reduced wheat cultivation costs by 15%, increased net returns by nearly 20%, improved yields by about 11%, and saved up to 18 labour hours per acre during every irrigation cycle.


Women also reported lower drudgery and more time for income-generating activities. These findings reinforce evidence from across India that micro-irrigation improves productivity, profitability and resilience. While economic and environmental benefits of micro-irrigation are well established across India, the study explains why we cannot reap the full benefits.

India doesn't have a technology gap. It has an adoption gap. The study found:

Although 60% of surveyed farmers had adopted water-saving technologies, adoption reached 87% among large farmers but only 59% among smallholders.

Regression analysis showed that education, extension services, farmer organisations, digital information, PM-KISAN support and reliable electricity significantly increased adoption. Participation in training improved adoption by nearly 65%. Yet, knowledge-attitude-practice (KAP) analysis revealed a striking disconnect. While 72% of farmers knew that micro-irrigation conserves water, fewer than 46% translated that knowledge into good farming practices.

The agent-based model helped identify practical ways to encourage more farmers to adopt micro-irrigation. The simulations suggest that awareness campaigns, peer learning from fellow farmers and field demonstrations can substantially increase interest in the technology.

When these efforts are combined with modest improvements in farmers' incomes and financial support through subsidies, adoption could increase even further. The model estimates that, among 40% of farmers who had not adopted micro-irrigation during the study, around 23% could become interested in adopting it if they perceive sufficient benefits (if mean utility is reduced). Among these potential adopters, about 13% could adopt the technology if they can afford the required investment.

Three low-cost policy shifts can rapidly accelerate adoption:

Make field demonstrations, peer learning and exposure visits integral to every micro-irrigation programme rather than treating them as optional extension activities.

To sustain adoption by farmers, it's necessary to deploy krishi didis/sakhis, trained SHG members, krishi vigyan kendras (KVKs) and farmer producer organisations (FPOs) as village-level 'water ambassadors' to build farmers' confidence, provide hands-on guidance and encourage sustained adoption.

Complement financial incentives with continuous capacity-building through digital advisory platforms, refresher training and local technical support. KAP analysis suggests that knowledge or tech are not enough. Policies must help farmers translate positive knowledge and attitudes into sustained on-field practice. This requires a grassroots support system for farmers, as it was done in the primary health delivery system.

India's Green Revolution solved the challenge of food security. The next revolution must secure water security. Because in an era of climate uncertainty, every drop saved is not merely water conserved but prosperity created.
