Punjab groundwater crisis is deepening inequality among farmers

Punjab extracts far more groundwater than nature replenishes, driven largely by its rice-wheat system and cheap irrigation power. Falling water tables also hurt small farmers more because deeper wells require greater investment. The crisis is therefore ecological as well as economic.

Event date:

REq1
  1. Context1 / 4
    • Punjab faces severe groundwater over-extraction, closely linked to its water-intensive rice-wheat cropping system.
    • The supplied editorial cites an extraction rate of about 152% and says roughly 72% of 153 assessed units are over-exploited.
    • The official 2025 national groundwater compilation reports Punjab’s extraction stage at 156.36%, with 26.27 billion cubic metres extracted.
    • Agriculture is the main groundwater user, with rice and wheat irrigation placing particularly high pressure on aquifers.
    • Falling water tables require deeper wells, stronger pumps and greater capital investment, making depletion both an environmental problem and an issue of unequal access to irrigation.
  2. Key highlights2 / 4

    Rice-wheat lock-in: Assured procurement, established markets and irrigation access made rice and wheat less risky than many alternative crops.

    Electricity incentive: Free or highly subsidised farm power reduces the direct cost of pumping groundwater.

    Deeper extraction: As water tables fall, farmers need deeper tubewells and more powerful pumps, increasing irrigation costs.

    Unequal capacity: Larger farmers generally have greater access to capital for adapting to deeper groundwater levels. Farmers unable to finance new wells may depend on water purchased from those with deeper tubewells.

    Efficiency finding: Recent research in Sangrur and Barnala found lower paddy groundwater productivity on larger farms in some measures, showing that profitability and water efficiency are not identical.

  3. Key concepts3 / 4
    1. Stage of groundwater extraction
    • The stage of groundwater extraction compares annual groundwater withdrawal with the groundwater available for extraction. A value above 100% means annual extraction exceeds the assessed extractable groundwater resource.
    • It does not mean that an aquifer contains no water.

    News connection: Punjab’s extraction stage shows withdrawals running well above the assessed sustainable annual resource.

    1. Water-energy-agriculture nexus
    • The water-energy-agriculture nexus describes how irrigation, electricity and crop choices influence one another. Cheap electricity lowers the cost of operating pumps, while water-intensive crops increase electricity demand and groundwater extraction.

    News connection: Punjab’s irrigation system shows how power subsidies and crop incentives can jointly shape groundwater use.

    1. Groundwater productivity
    • Groundwater productivity measures how much agricultural output or economic value is produced from a given amount of groundwater. High crop income does not necessarily mean water is being used efficiently.
    • A 2026 study of Sangrur and Barnala found differences in groundwater productivity and efficiency across farm sizes.

    News connection: Farm profitability and groundwater sustainability should be assessed separately.

    1. Common-pool resource
    • Groundwater has features of a common-pool resource because many users draw from the same aquifer. Water withdrawn by one user can reduce what remains accessible to others.
    • Regulation is difficult because extraction happens through many individual wells.

    News connection: Falling groundwater levels can favour farmers able to invest in deeper pumping equipment while increasing costs for others.

  4. Way forward4 / 4

    Change incentives: Reward electricity savings instead of linking farm support to unrestricted pumping. Punjab’s Pani Bachao, Paisa Kamao scheme follows this approach.

    Support diversification: Alternative crops need reliable procurement, storage, processing and markets if farmers are expected to move away from water-intensive paddy.

    Reduce capital barriers: Shared irrigation infrastructure, farmer collectives and better canal access can reduce dependence on individually financed deep tubewells.

    Target support carefully: Farm assistance could follow cultivators, including small farmers and tenants, rather than reward groundwater extraction itself.

Practice questions

  1. With reference to the stage of groundwater extraction, consider the following statements: 1. It compares groundwater extraction with the annual extractable groundwater resource. 2. A value above 100% indicates extraction exceeds the assessed extractable resource. 3. A value above 100% necessarily means that no groundwater remains in the aquifer. Which of the statements given above are correct?

    1. 1 only
    2. 1 and 2 only
    3. 2 and 3 only
    4. 1, 2 and 3
    Show answer

    Answer: B. Statements 1 and 2 are correct. The indicator measures annual extraction pressure; it does not mean that the aquifer has become completely empty.

    Difficulty: medium · statement

  2. Consider the following factors: 1. Assured procurement of water-intensive crops 2. Subsidised electricity for agricultural pumping 3. Easy access to tubewell irrigation 4. Weak markets for alternative crops Which of the above can encourage excessive groundwater use in agriculture?

    1. 1 and 2 only
    2. 1, 2 and 3 only
    3. 2, 3 and 4 only
    4. 1, 2, 3 and 4
    Show answer

    Answer: D. All four can reinforce cultivation choices that depend heavily on groundwater.

    Difficulty: medium · statement

  3. With reference to the water-energy-agriculture nexus, consider the following statements: 1. Electricity pricing can influence groundwater extraction. 2. Cropping patterns can affect both water and electricity demand. 3. Improving pump efficiency alone necessarily reduces total groundwater extraction. Which of the statements given above are correct?

    1. 1 only
    2. 1 and 2 only
    3. 2 and 3 only
    4. 1, 2 and 3
    Show answer

    Answer: B. Statements 1 and 2 are correct. Efficiency improvements need not reduce total extraction if incentives still encourage heavy groundwater use.
