Examine how differential access to groundwater is creating new forms of rural inequality in India. What policy interventions can protect marginal farmers?

Groundwater is India's largest source of irrigation, but it is a private good drawn from a common aquifer — so as water tables fall, access shifts from being a right of land to a function of capital. With 730 of 6,762 assessment units (10.80%) already 'over-exploited' nationally [1], and Punjab extracting 152% of its annual recharge [2], depletion is producing not just scarcity but a new hierarchy in the countryside.

How depletion converts into inequality

• Capital-determined access: chasing a falling water table needs deeper borewells and higher-horsepower pumps. Studies of Punjab find wealthier farmers extract disproportionately more, while marginal farmers — who use water more efficiently — are pushed out [2].
• Emergence of informal water markets: small farmers increasingly buy water from tubewell owners, turning a common resource into a rent extracted by the better-off [2].
• Regressive cost escalation: deeper pumping raises energy and capital costs, which are proportionately heavier on sub-hectare holdings, squeezing already thin margins.
• Subsidy capture: free/subsidised farm power lowers the marginal cost of pumping and benefits most those who pump most, reinforcing the gap [3].
• Livelihood risk: loss of assured irrigation raises tenancy, indebtedness and distress migration among marginal cultivators.

Policy interventions to protect marginal farmers

• Extend Atal Bhujal Yojana — its community-led aquifer management with micro-irrigation, crop diversification and feeder separation [4] should cover stressed States currently outside its seven-State ambit [4][2].
• Scale incentive-based conservation: Punjab's Paani Bachao Paisa Kamao retains free power but pays cash for unused units [3]; a higher per-unit reward for small and marginal holdings would make it equity-enhancing.
• Solarise pumping with buy-back, as the NITI Aayog–World Bank energy–water–agriculture work recommends, so saved water becomes income rather than a loss [5].
• Diversification with assured procurement, storage and processing for maize, pulses and oilseeds, plus group tubewells and micro-irrigation subsidies targeted at marginal farmers.

Groundwater inequality is ultimately an artefact of policy signals, not of nature. Aligning power pricing, procurement and aquifer governance — and weighting each towards the smallholder — can convert conservation into a source of income rather than exclusion, advancing both water security and the constitutional promise of distributive justice under Article 39(b).
