UPSC CSE Context Why in News: India's CBG push under SATAT and GOBARdhan schemes has limited progress, while global biogas expansion raises food security concerns. Syllabus Connection: Economy: Energy security, renewable energy, biofuels; Agriculture: crop diversification, food security; Environment: waste to energy. Exam Relevance: Relevant for questions on energy security, renewable energy policy, agricultural diversification, and trade offs between energy and food security. Core Issue Biogas potential vs. limited progress and crop shift risks. Key Development: SATAT target of 5,000 CBG plants by 2023 achieved only 132 by June 2026. Stakeholders: Government of India Farmers Private investors Oil marketing companies Ministry of Petroleum and Natural Gas Ministry of New and Renewable Energy Static Knowledge High Value Background: Biogas is produced by anaerobic digestion of organic matter; CBG is purified biogas with 90% methane, chemically identical to CNG. India imports 85% of crude

## UPSC CSE Context **Why in News:** India's CBG push under SATAT and GOBARdhan schemes has limited progress, while global biogas expansion raises food security concerns. **Syllabus Connection:** Economy: Energy security, renewable energy, biofuels; Agriculture: crop diversification, food security; Environment: waste-to-energy. **Exam Relevance:** Relevant for questions on energy security, renewable energy policy, agricultural diversification, and trade-offs between energy and food security. ## Core Issue Biogas potential vs. limited progress and crop shift risks. **Key Development:** SATAT target of 5,000 CBG plants by 2023 achieved only 132 by June 2026. **Stakeholders:** - Government of India - Farmers - Private investors - Oil marketing companies - Ministry of Petroleum and Natural Gas - Ministry of New and Renewable Energy ## Static Knowledge **High-Value Background:** - Biogas is produced by anaerobic digestion of organic matter; CBG is purified biogas with >90% methane, chemically identical to CNG. - India imports ~85% of crude oil and ~90% of LPG transits Strait of Hormuz, making energy security vulnerable. **Concepts in Context:** - SATAT (Sustainable Alternative Towards Affordable Transportation) aims to set up CBG plants for use as automotive fuel. - GOBARdhan (Galvanising Organic Bio-Agro Resources Dhan) scheme promotes waste-to-wealth through community biogas plants. **Institutions and Mechanisms:** - GOBARdhan scheme under Swachh Bharat Mission. ## Dynamic Analysis ### Economy - CBG can reduce import dependence and improve energy security, but high upfront costs and lack of credit deter private investment. - Government incentives like accelerated depreciation and tax holidays could improve viability. - Ethanol pricing policy favoring maize-based ethanol has skewed cropping patterns, increasing maize area at expense of pulses and oilseeds. ### Agriculture and Food Security - Maize cultivation surged due to higher ethanol prices, threatening crop diversity and food security as pulses and oilseeds output stagnated. - Economic Survey 2026 noted maize yield increase but stagnation in soybeans, sunflower, rapeseed, peanuts, and millets. - States like Maharashtra and Karnataka see maize competing with pulses, oilseeds, and cotton for land and water. ### International Relations - India's energy security is tied to West Asia stability; CBG can reduce dependence on imported LPG and crude. - Germany's experience shows that biogas incentives can distort agriculture, requiring regulatory caps. ## Prelims Takeaways - GOBARdhan scheme provides grants up to ₹50 lakh per district for community biogas plants. ## Mains Value Addition **Arguments:** - CBG offers a triple benefit: energy security, waste management, and rural income support. - However, without proper safeguards, biogas promotion can distort cropping patterns and threaten food security. - Financial incentives alone are insufficient; infrastructure and credit access are critical bottlenecks. - India can learn from Germany's cap on maize use in biogas to prevent monoculture. **Examples:** - Germany's Renewable Energy Sources Act (2000) boosted biogas but led to 'corn mania', forcing a cap on maize use. **Data Points:** - Maize yield increased from 2.56 t/ha (FY16) to 3.78 t/ha (FY25); maize-based ethanol price CAGR 11.7% (FY22-FY25). **Counterpoints:** - CBG production is still nascent; scaling up may face land-use competition and water scarcity. - Ethanol blending targets may conflict with food security if not managed carefully. ## Way Forward - Provide easier access to formal credit and reduce upfront technology costs through subsidies. - Diversify feedstock for CBG to include agricultural residues and municipal waste, reducing pressure on food crops. - Implement a stable pricing mechanism for CBG to attract private investment.
