What Happened
- India's aggressive ethanol blending programme — targeting 20% ethanol blending in petrol (E20) — is triggering resistance from farmers in multiple states who fear that ethanol-producing plants will deplete scarce groundwater resources.
- Hundreds of farmers in Tibbi, Rajasthan marched against a proposed ethanol plant in late March 2026, with farmer Madan Dugesar articulating the central concern: "This factory will take away our water. No one asked us before starting the work."
- Similar protests have emerged in Telangana, Maharashtra, and Uttar Pradesh, as ethanol expansion moves into water-stressed agricultural regions.
- The core tension is that producing one litre of ethanol from sugarcane consumes approximately 2,860 litres of water (per NITI Aayog estimates) — a massive water footprint in regions where groundwater is already critically over-exploited.
- The Economic Survey 2025-26 had flagged early warning signs of ethanol incentives reshaping crop priorities, with maize displacing pulses, oilseeds, and millets in states like Maharashtra and Karnataka.

National Policy on Biofuels 2018 and the E20 Programme
The National Policy on Biofuels (NPB) 2018, effective May 16, 2018, set an indicative target of 20% ethanol blending in petrol by 2030. In 2022, this target was advanced to Ethanol Supply Year (ESY) 2025-26, five years earlier than originally planned. India achieved 10% blending ahead of schedule (June 2022) and reached approximately 18% by ESY 2024-25, with the E20 milestone essentially completed in 2025. The programme is managed by Oil Marketing Companies (OMCs) under the Ministry of Petroleum and Natural Gas, with ethanol sourced primarily from sugarcane molasses and juice, and increasingly from maize and other grains.
- NPB 2018: effective May 16, 2018; indicative E20 target originally by 2030
- Target advanced to ESY 2025-26 by 2022 amendment
- Blending progress: 10% (June 2022), 12.06% (ESY 2022-23), 14.60% (ESY 2023-24), ~18% (ESY 2024-25)
- Ethanol feedstock: sugarcane juice/molasses (primarily), maize, damaged food grains, rice straw, bagasse
- Primary feedstock policy change (2022): allowed direct sugarcane juice to ethanol (previously only B-heavy and C-heavy molasses)
- Administered ethanol procurement price (ex-mill): varies by feedstock — sugarcane-based ethanol highest; grain-based lower
- Total ethanol production capacity: India significantly expanded distillery capacity to meet E20 targets
Connection to this news: India has largely achieved its E20 target, but the social and ecological costs of that achievement — water-intensive feedstock cultivation in stress regions, crop displacement, and farmer protests — are now becoming visible, signalling that the next phase of biofuel expansion requires more careful spatial and ecological planning.
Groundwater Governance and India's Over-Exploitation Crisis
India is the world's largest extractor of groundwater, accounting for approximately 25% of global groundwater extraction. About 89% of India's groundwater use goes to agriculture, primarily for irrigation of water-intensive crops like sugarcane, rice, and maize — the very crops that are also key ethanol feedstocks. The Central Ground Water Board (CGWB) classifies aquifer units into "Safe," "Semi-Critical," "Critical," and "Over-Exploited" categories; as of recent assessments, 16% of India's assessment units are over-exploited.
- India: world's largest groundwater extractor (~25% of global extraction)
- Agriculture's share of groundwater use in India: ~89%
- Central Ground Water Authority (CGWA): regulatory body for groundwater management under Environment Protection Act, 1986
- CGWB classifies blocks: Safe, Semi-Critical, Critical, Over-Exploited
- ~16% of assessment units in India are classified as over-exploited (primarily Punjab, Haryana, Rajasthan, parts of UP)
- Sugarcane: most water-intensive major crop — ~1,500–2,000 litres per kg of sugar
- PM Krishi Sinchai Yojana (PMKSY): "More crop per drop" — promotes water-use efficiency in agriculture
- Jal Shakti Abhiyan: national groundwater conservation mission
Connection to this news: The ethanol plant protests in Rajasthan are a direct response to water anxiety in one of India's most groundwater-stressed states — where promoting water-intensive ethanol feedstock cultivation would accelerate aquifer depletion.
Food-Fuel Trade-off and Food Security Concerns
When agricultural land and water are redirected from food crops to biofuel feedstocks, it creates a food-fuel trade-off. Global experience — particularly from the US maize ethanol programme and the EU biofuel mandates — shows that biofuel policies can drive up food prices by competing with food production for land, water, and labour. In India, the shift of land from pulses, oilseeds, and millets (critical for nutritional security) to maize and sugarcane (for ethanol) risks aggravating existing dietary deficiencies.
- Maize displacing pulses and oilseeds in Maharashtra and Karnataka — noted in Economic Survey 2025-26
- India's pulse deficit: India is import-dependent for pulses (primarily tur, urad, moong); further land shift to ethanol crops worsens pulse availability
- Water footprint of ethanol from sugarcane: ~2,860 litres per litre of ethanol (NITI Aayog estimate)
- ICCT (International Council on Clean Transportation) analysis: India's ethanol programme has pushed crop priorities off-track from food security goals
- Article 47 (DPSP): directs the state to raise the level of nutrition and standard of living of citizens — a food security mandate in the Constitution
- India's National Food Security Act, 2013: covers 81.35 crore people — stable food production is constitutionally and legally essential
Connection to this news: Farmer protests against ethanol plants are an early warning of the food-fuel conflict becoming acute — policymakers must balance India's energy security and climate goals (reducing oil imports, cutting vehicular emissions) against food security and water sustainability.
