Three-Fourths of India's Irrigation Runs on Electricity: Reading the 6th Minor Irrigation Census
23.14 million schemes, 95% groundwater-fed and 96.6% privately owned — the census maps a quiet electrification of Indian farming, and its groundwater cost
What happened
Numbers like '76% of irrigation now runs on electricity' are exactly the kind of exam-ready data point that turns a generic agriculture answer into an evidence-backed one. But the census rewards a second reading: the same electrification that boosts farm output also underwrites the free-power-plus-groundwater cycle that is draining India's aquifers. Holding both — the productivity gain and the sustainability cost — is the analytical move examiners look for.

Minor Irrigation (MI) schemes are defined by a culturable command area (CCA) of up to 2,000 hectares; anything above that is Major or Medium irrigation.
●MI schemes are of two broad types: groundwater schemes (dug wells, shallow tube wells, medium tube wells, deep tube wells) and surface-water schemes (surface flow and surface lift). The Census of Minor Irrigation Schemes is conducted by the Ministry of Jal Shakti (Department of Water Resources, RD & GR) roughly every five years; the 6th Census has reference year 2017-18.
●Key numbers to retain: 23.14 million total schemes; 94.8% groundwater vs 5.2% surface water; 76% electricity-powered vs 22.2% diesel; 96.6% privately owned; women own 18.1%. The dominance of groundwater and cheap electricity connects directly to the Central Ground Water Board's assessment of over-exploited blocks and to state-level free/subsidised farm-power policies.
India irrigates mostly from private groundwater wells running on subsidised electricity — a structure that maximises access but externalises the cost onto falling water tables.
◎ In Simple Words
Farmers need water for their crops, and most of them get it by pumping it out from under the ground using wells and tube-wells. A big government survey counted all these small water systems and found there are about 23 crore-plus of them — and most now run on electricity instead of diesel. That is good because electric pumps are cheaper and cleaner. But there is a problem: because power for farms is very cheap, farmers pump a lot of water, and the underground water is running low in many places. So the same thing that helps grow more food is also using up a hidden resource too fast.
Factual Pointers
Practice · 2 questions
With reference to the Census of Minor Irrigation Schemes in India, consider the following statements:

2. The Census is conducted by the Ministry of Agriculture and Farmers Welfare.
3. As per the 6th Census, groundwater schemes vastly outnumber surface-water schemes.
Which of the statements given above is/are correct?
The predominance of electricity as the energy source for minor irrigation in India is most directly linked to which of the following policy concerns?
Mains Practice Questions
The 6th Minor Irrigation Census shows that Indian irrigation is overwhelmingly groundwater-based and electricity-powered. Critically examine how the subsidised-power-and-groundwater nexus threatens long-term water security, and suggest incentive-compatible reforms. (250 words, GS3)
"India's water challenge is fundamentally a governance challenge of managing millions of private extractors, not a shortage of engineering." Discuss in the light of the structure of minor irrigation in India. (250 words, GS3)
