Groundwater crisis in Punjab is widening social and economic divide, finds study
Worth reading — 1 past UPSC question on this theme (Mains GS-3 2020).
2-minute summary
A study titled 'Unequal Burden of Groundwater Depletion in Punjab' highlights a severe ecological and socio-economic crisis in Punjab, where 76.47% of groundwater blocks are classified as over-exploited—the highest rate in India. Driven by the intensive cultivation of water-intensive crops like paddy and wheat, combined with low utilization of surface canal water, the crisis is widening the state's socio-economic divide. Large, capital-rich farmers are able to secure free agricultural electricity and invest in deep tubewells and high-capacity submersible pumps to access receding water tables. Conversely, resource-poor small and marginal farmers lack the capital to deepen their wells, watching helplessly as shallow wells dry up. This creates an inequitable dynamic where large farmers, who contribute most to aquifer depletion, reap the highest economic returns, while smallholders bear the brunt of the environmental externalities, including deteriorating water quality, land subsidence, and dried-up surface water bodies.
Why it's in the news
A recent study published in the Economic and Political Weekly, titled 'Unequal Burden of Groundwater Depletion in Punjab', reveals that Punjab has the highest percentage of over-exploited groundwater blocks in India (76.47%), and warns that the resulting crisis is deepening socio-economic inequality.
Facts to remember
- A study titled 'Unequal Burden of Groundwater Depletion in Punjab' reveals that 76.47% of Punjab's groundwater blocks are classified as over-exploited.
- Punjab has the highest rate of over-exploited groundwater blocks in India.
- The crisis is driven by the intensive cultivation of water-intensive crops like paddy and wheat combined with low utilization of surface canal water.
Background and context
The roots of Punjab's groundwater crisis trace back to the Green Revolution of the late 1960s, which introduced high-yielding varieties of wheat and rice. To support food security, the government incentivized these crops through assured procurement under the Minimum Support Price (MSP) regime. Over the decades, this led to a shift away from traditional, water-efficient crops (like pulses and maize) to a water-intensive paddy-wheat monoculture. The introduction of free agricultural electricity in Punjab during the late 1990s further decoupled the economic cost of pumping from resource scarcity, leading to unregulated, exponential extraction of groundwater via tubewells, while the state's canal irrigation network remained underutilized.
Constitutional provisions
- Article 21 — The Supreme Court of India has interpreted the Right to Life to include the right to clean drinking water and a pollution-free environment, both of which are threatened by severe groundwater depletion and contaminant ingress.
- Article 39(b) — A Directive Principle of State Policy directing the State to ensure that the ownership and control of the material resources of the community are so distributed as best to subserve the common good, highlighting the inequity in groundwater access.
- Article 48A — Directs the State to endeavor to protect and improve the environment and to safeguard the forests and wildlife of the country.
- Seventh Schedule (State List, Entry 17) — Water, including water supplies, irrigation and canals, drainage and embankments, water storage and water power, falls primarily under the state's legislative domain.
Committees and reports
- Johl Committee Reports (1986 & 2002) — Recommended diversifying at least 20% of Punjab's agricultural area under paddy and wheat to other high-value, water-efficient crops like oilseeds, pulses, and vegetables.
- Mihir Shah Committee on Water Reforms — Recommended restructuring the Central Water Commission (CWC) and Central Ground Water Board (CGWB) into a single National Water Commission (NWC) to manage water resources in an integrated, sustainable manner.
Government schemes
- Atal Bhujal Yojana (ABY) — A Central Sector Scheme focusing on community-led sustainable groundwater management, water budgeting, and demand-side interventions in identified water-stressed areas.
- Pradhan Mantri Krishi Sinchayee Yojana (PMKSY) - Per Drop More Crop — Focuses on improving water-use efficiency at the farm level through micro-irrigation technologies like drip and sprinkler systems.
International organisations
- World Bank — Co-funds the Atal Bhujal Yojana and supports various state-level water resource management and climate-resilient agriculture initiatives in India.

Mains practice: The groundwater crisis in Northwest India is not merely an environmental disaster but a socio-economic equalizer in reverse. Analyze this statement in the context of agricultural subsidies and resource equity.
The groundwater crisis in Northwest India, particularly in Punjab where 76.47% of groundwater blocks are over-exploited, has transcended ecological boundaries to become a profound socio-economic challenge. While environmental degradation affects the entire region, its economic fallout is highly regressive, disproportionately penalizing small and marginal farmers.
How the Crisis Widens the Socio-Economic Divide:
• Capital Disparity in Extraction: Groundwater is a common-pool resource, but access is highly privatized. Large farmers possess the financial capital to continuously deepen borewells and install high-capacity submersible pumps to chase the receding water table. Small and marginal farmers, lacking capital, watch their shallow tubewells dry up.
• Regressive Impact of Subsidies: Blanket free agricultural electricity, intended to protect vulnerable farmers, is disproportionately captured by capital-rich farmers. They operate more high-powered pumps, siphoning the bulk of the groundwater to fuel a water-intensive cropping pattern.
• Input Costs and Debt Traps: As water tables plunge, the cost of drilling deeper and upgrading pumps escalates. For smallholders, these capital expenditures lead to rising informal debt, pushing them toward agrarian distress, while large farmers maintain high returns per unit cost.
• Environmental Externalities: Deteriorating water quality due to contaminant ingress and land subsidence affects public health and land productivity. Smallholders lack the resources to mitigate these health and environmental hazards, further entrenching poverty.
Conclusion:
To prevent groundwater depletion from further fracturing rural society, India must transition from supply-side extraction to demand-side management. This requires rationalizing power subsidies (e.g., Direct Benefit Transfer of electricity subsidy), incentivizing crop diversification away from paddy via assured MSP for pulses and oilseeds, and promoting community-led water budgeting under initiatives like the Atal Bhujal Yojana.
Prelims practice questions
Q1. With reference to groundwater governance in India, consider the following statements: 1. The Central Ground Water Authority (CGWA) is a statutory body constituted under the Water (Prevention and Control of Pollution) Act, 1974. 2. Water is a subject listed under the Concurrent List of the Seventh Schedule of the Constitution of India. Which of the statements given above is/are correct?
- 1 only
- 2 only
- Both 1 and 2
- Neither 1 nor 2
Answer: D. Statement 1 is incorrect: The Central Ground Water Authority (CGWA) was constituted under Section 3(3) of the Environment (Protection) Act, 1986, not the Water Act of 1974. Statement 2 is incorrect: Water is primarily a State subject under Entry 17 of the State List (List II) of the Seventh Schedule, though the Union has powers under Entry 56 of the Union List for regulation of inter-state rivers.
Q2. According to official national assessments, which of the following states has the highest percentage of over-exploited groundwater blocks in India?
- Punjab
- Haryana
- Rajasthan
- Tamil Nadu
Answer: A. According to the latest studies and national compilations, Punjab has the highest percentage of over-exploited groundwater blocks in the country, standing at approximately 76.47%.
Q3. Which of the following measures are considered effective demand-side interventions for managing groundwater depletion in agriculture? 1. Direct Benefit Transfer (DBT) of electricity subsidies to farmers. 2. Promoting the cultivation of short-duration paddy varieties like PR-126. 3. Implementation of community-led water budgeting. Select the correct answer using the code given below:
- 1 and 2 only
- 2 and 3 only
- 1 and 3 only
- 1, 2 and 3
Answer: D. All three are effective demand-side interventions. DBT of electricity subsidies discourages wasteful pumping. Short-duration paddy varieties like PR-126 require significantly less water compared to long-duration varieties. Community-led water budgeting (as promoted under Atal Bhujal Yojana) helps villages plan crop patterns based on local water availability.
