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

Frequently Asked
· People also askWhat is the Minor Irrigation Census?
It is a periodic survey by the Ministry of Jal Shakti of all irrigation schemes with a culturable command area up to 2,000 hectares — groundwater wells, tube wells and small surface structures. The 6th Census has reference year 2017-18.
PrelimsMinor irrigation is split into groundwater schemes (dug, shallow, medium and deep tube wells) and surface-water schemes (flow and lift). It is the backbone of Indian farming, in contrast to Major/Medium irrigation projects above 2,000 hectares.

How many minor irrigation schemes does India have?
India has 23.14 million minor irrigation schemes per the 6th Census — a 6.6% rise over the 5th. Of these, 21.93 million (94.8%) are groundwater-based and only 1.21 million (5.2%) are surface-water; 96.6% are privately owned and 18.1% owned by women.
GS3This overwhelming private, groundwater dominance means India's food security rests not on state-built dams but on millions of individually owned wells — a decentralised structure that is nearly impossible to regulate directly.

What powers most of India's irrigation?
About 76% of India's minor irrigation schemes run on electricity, against 22.2% on diesel, per the 6th Census. This electrification, cheapened by subsidised farm power, drives the over-extraction of groundwater — the so-called 'energy-irrigation nexus'.
GS3Because cheap or free electricity lowers the marginal cost of pumping, it encourages over-extraction. Fixing it needs incentive-compatible reforms — metering, direct power transfers, and solarisation via PM-KUSUM — rather than blunt subsidy withdrawal.

Which state has the most minor irrigation schemes?
Uttar Pradesh has the largest number of minor irrigation schemes in India (about 17.2% of the total), followed by Maharashtra (~15.4%) and Madhya Pradesh (~9.9%), per the 6th Census.
GS1 · GS3These are among India's most agriculturally intensive and, in parts, most groundwater-stressed states — the Central Ground Water Board classifies many of their assessment blocks as over-exploited or critical.

Why does India's groundwater dependence matter?
India is the world's largest extractor of groundwater — drawing more than the United States and China combined, roughly a quarter of global withdrawal. With 94.8% of schemes tapping aquifers and extraction cheapened by subsidised power, water tables are falling across large regions.
UPSC angleFalling tables force farmers to deepen wells and install bigger pumps, raising costs and energy use in a self-reinforcing cycle that hurts small farmers most. Atal Bhujal Yojana promotes community aquifer management as a demand-side response.
