Revised 17 September 2026 · v1.0.0 · what changed

Irrigation policy in India is usually discussed as a public-works question — canal networks, dam commands, budget allocations. The government's own 6th Minor Irrigation Census, reference year 2017-18, counts something different: 23.14 million minor irrigation schemes nationwide, of which 21.93 million — 94.8% — are groundwater (borewells and tubewells), not canal-fed. And of every kind of scheme, 96.6% are privately owned. India's irrigation, at the level the census actually measures, is overwhelmingly a private, self-built, groundwater system.

What the census counted

Growth over the previous (5th) census was +1.42 million schemes overall, with groundwater schemes up 6.9% and surface-water schemes up just 1.2% — the expansion since the last count has itself been almost entirely a groundwater story. 97.0% of counted schemes are recorded as currently in use. In a first for this census round, ownership was also broken down by gender: 18.1% of individually-owned schemes are owned by women.

Who pays for it

Of the schemes with a single, identifiable source of finance — 60.2% of the total — 79.5% were financed by the individual farmer's own savings. That is the standing figure this piece uses, and it applies specifically to that 60.2% subset, not to every scheme in the census; schemes financed by a mix of sources, institutional credit, or government support fall outside it. Even with that caveat attached, it points the same direction as the ownership numbers: where a single financing source can be identified at all, it is overwhelmingly the owner's own money, not a loan or a subsidy.

What the public money bought, on the peer-reviewed evidence

A separate, peer-reviewed measurement of the public half of this picture exists: Bathla, Kannan & Das, "Public investment in irrigation across the Indian states: Financial recovery and governance" (Agricultural Economics Research Review 37(1), pp. 93–112, 2024), which examines public capital formation in irrigation across 20 states over four decades. Its own published abstract states that rising public investment "has barely corresponded" with net irrigated area, irrigation potential utilised, or financial recovery on that investment. The full paper is paywalled, so this piece cites only the abstract's own wording and does not attribute any additional figures to it.

Put the two sources together: the infrastructure that actually irrigates most of India's cropped area is privately built and privately financed, groundwater-dominated, and growing mostly on the groundwater side — while the peer-reviewed measurement of the public investment running alongside it finds that spending has not tracked what irrigation it produced or recovered.

The takeaway

The usual irrigation-policy conversation is about canals, dams and budget allocations. The census data says most of India's actual irrigation infrastructure was never that: it is millions of individually owned borewells, installed and paid for out of farmers' own pockets, expanding faster than the surface-water systems the public irrigation budget is built around. Any policy discussion of irrigation investment that doesn't start from that ownership pattern is discussing a minority of the system.

What would fix this

• The Ministry of Jal Shakti should publish the all-India summary volume of the 7th Minor Irrigation Census, with a table comparing each headline figure against the 6th census, so that the ownership and groundwater shares here, still dated to 2017–18, can be updated from an official national total.
• The Ministry of Jal Shakti should report, in future Minor Irrigation Census volumes, area irrigated and the number of distinct owners alongside the count of schemes, so that the private share of India's irrigation can be stated in hectares and farmers, not only in schemes.
• The Ministry of Jal Shakti should publish the financing breakdown for schemes with mixed sources of finance, not only the 60.2 per cent with a single source, so that the 79.5 per cent own-savings figure can be extended to the whole census rather than one subset of it.
• The Department of Water Resources should publish an annual state-wise series of public capital spending on irrigation set against irrigation potential created, potential utilised and net irrigated area, so that the finding that public investment has barely tracked results can be checked from open official data rather than a paywalled paper.
• State electricity regulatory commissions should publish the annual agricultural power subsidy per pump set, split between metered and unmetered connections, so that the running cost of privately built groundwater irrigation can be set beside the census's ownership and financing figures.
