Answer

Ethanol blending is a significant part of India’s strategy to reduce its dependence on fossil fuels. Launched in 2003, the Ethanol Blended Petrol (EBP) Programme aims to achieve 20% ethanol blending (E20) by 2025-26. India currently imports about 80% of its oil to meet its energy needs, with fossil fuels accounting for 75% of energy consumption. Ethanol blending reduces oil imports, curbs pollution, and supports rural agriculture.

Ethanol Blending as Key Component in Reducing Fossil Fuel Dependence

• Reduced Oil Imports: Ethanol blending helps reduce India’s reliance on fossil fuel imports, contributing to energy security and saving foreign exchange reserves.
  For example: India aims to cut 30 million tons of CO2 emissions annually by replacing petrol with ethanol blends, improving the energy mix.
• Environmental Benefits: Ethanol burns cleaner than fossil fuels, lowering greenhouse gas emissions and contributing to climate change mitigation efforts.
  For example: According to the Ministry of Petroleum, ethanol blending reduces CO2 emissions by 18-20% compared to conventional petrol.
• Boost for Rural Economy: Ethanol production offers additional income to farmers, particularly sugarcane and maize producers, supporting rural livelihoods.
  For example: The National Policy on Biofuels 2018 encourages ethanol production from excess crops, improving farmers’ income.
• Domestic Energy Source: Ethanol from agricultural residues and food grains increases energy self-sufficiency, reducing the reliance on fluctuating global oil markets.
  For example: India’s ethanol production capacity has reached 1,380 crore litres, contributing to energy security.
• Fuel Efficiency: Ethanol’s higher octane rating improves engine efficiency, reducing overall fuel consumption.
  For example: Blended fuels increase efficiency, lowering the overall demand for petroleum products as per NITI Aayog’s ethanol roadmap.

Impacts of Large-Scale Ethanol Production on Agriculture

Positive

• Increased Crop Demand: Ethanol production enhances the demand for sugarcane, maize, and other feedstocks, benefiting farmers.
  For example: Maharashtra and Uttar Pradesh have seen higher demand for sugarcane, leading to increased farmer incomes.
• Rural Employment: The establishment of ethanol production plants creates jobs in rural areas, boosting the local economy.
  For example: The interest subvention scheme supports new distilleries, creating over 5 lakh rural jobs.
• Diversified Agriculture: Farmers can switch to ethanol-producing crops, diversifying income sources and reducing dependency on single crops.
  For example: Sugarcane farmers in Karnataka have adopted ethanol production as an alternative revenue stream, enhancing resilience.
• Use of Surplus Crops: Ethanol production from surplus grains and damaged crops prevents wastage and supports food security.
  For example: Ethanol from damaged grains in the central pool contributes to ethanol production without impacting the food supply chain.
• Increased Water Efficiency: Advanced irrigation techniques introduced for ethanol crops improve overall water efficiency in agriculture.
  For example: Drip irrigation systems implemented for sugarcane cultivation have enhanced water productivity by 20-30%.

Negative

• Water-Intensive Crops: Ethanol production from sugarcane is highly water-intensive, leading to resource depletion.
  For example: Producing 1 kg of sugar requires 1,500–2,000 litres of water, which strains water resources in drought-prone regions.
• Impact on Food Prices: Diverting food grains to ethanol production may increase food prices, affecting food affordability.
  For example: Increased demand for maize for ethanol production has led to a rise in poultry feed prices, impacting the livestock sector.
• Land Use Conflicts: Large-scale ethanol production may lead to land-use conflicts, with agricultural land diverted from food production to biofuel crops.
• Monoculture Practices: The emphasis on ethanol-producing crops could lead to monoculture, reducing biodiversity and soil health.
  For example: Excessive sugarcane cultivation in Maharashtra has led to soil degradation and loss of crop diversity in certain regions.
• Increased Fertiliser Use: Ethanol crops require heavy use of fertilisers, which can lead to soil and water contamination.
  For example: The use of nitrogen-based fertilisers in sugarcane production has contributed to eutrophication in nearby water bodies.

Impacts of Ethanol Production on Food Security

Positive

• Utilising Surplus Grains: Ethanol production from excess and damaged grains prevents wastage and supports food security.
  For example: NITI Aayog’s roadmap highlights the use of surplus grains to meet blending targets, contributing to food supply stability.
• Income Stability for Farmers: Ethanol production provides additional income to farmers, ensuring they have financial resources for food security. 
• Improved Agricultural Practices: Ethanol production encourages the adoption of modern agricultural techniques, improving crop yields and food security.
  For example: The Pradhan Mantri Krishi Sinchayee Yojana promotes efficient water use for ethanol crops, enhancing overall productivity.
• Preventing Post-Harvest Losses: Ethanol production utilises crops that might otherwise face post-harvest losses, thus ensuring better food management.
  For example: Damaged grains diverted for ethanol production reduce losses in the Public Distribution System (PDS).
• Reduced Pressure on Imports: By producing ethanol domestically, India reduces its reliance on imported biofuels, ensuring greater control over food supply and fuel security.
  For example: The ethanol policy saved ₹40,000 crore in foreign exchange from fuel imports, according to the Ministry of Petroleum.

Negative 

• Food vs. Fuel Debate: Diverting food crops to ethanol production raises concerns about food security, especially in a hunger-prone nation.
  For example: India’s rank of 107 on the Global Hunger Index highlights the importance of prioritising food production over biofuel.
• Inflation in Food Prices: Increased demand for ethanol-producing crops can lead to inflated prices, affecting food affordability.
  For example: Rising maize prices due to ethanol demand has led to increased costs in the poultry and animal husbandry sectors.
• Displacement of Staple Crops: Ethanol production may displace essential food crops like rice and wheat, affecting food availability. 
• Vulnerability to Climate Change: Ethanol-producing crops are often more vulnerable to climatic changes, impacting food security in drought-prone areas. 
• Increased Import Dependence: If domestic ethanol production is insufficient, India may need to import grains, conflicting with food security goals. 

India’s push for ethanol blending as part of its energy transition strategy must be balanced with agricultural and food security needs. While it presents opportunities for reducing oil imports and boosting rural income, sustainable production methods, efficient resource use, and a focus on non-food feedstocks are crucial to avoid negative impacts on food security.
