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.
