How rice farmers can cut methane, and make money off it, Pg17

Key Highlights:

• Alternate Wetting and Drying (AWD) is a rice cultivation method that reduces methane emissions by periodically drying and re-flooding paddy fields.
• A study by Mitti Labs Ltd in Telangana's Warangal district during the 2024 kharif season showed water savings, reduced methane emissions, and maintained grain yields using AWD.
• Methane abatement carbon credits are trading at $15-25 per tonne of CO2 equivalent, potentially generating over Rs 3,300 per hectare for farmers.
• The Good Rice Alliance, including Bayer, Shell Energy India, and GenZero, has enrolled over 12,000 farmers across 13 states, reducing methane emissions by approximately 120,000 tonnes of CO2 per year.

Detailed Insights:

• Traditional rice farming involves continuous flooding, which suppresses weeds but creates anaerobic conditions that promote methane-producing microbes.
• AWD disrupts these anaerobic conditions, reducing methane emissions without significant yield loss, making it a "low effort, high impact" practice for smallholder farmers.
• Mitti Labs is generating methane emissions data through direct measurement in farmer fields, aiming to create verified carbon credits for sale in domestic and international markets.
• Buyers of carbon credits, such as data centers and airlines, use them to offset their emissions and achieve "net zero-carbon" targets.
• The Good Rice Alliance promotes AWD and direct seeding, bypassing nursery preparation and transplanting, to further reduce methane emissions.
• India is the world's top producer and exporter of rice, making the adoption of sustainable rice cultivation practices crucial for mitigating greenhouse gas emissions.

Key Concepts Involved:

• Alternate Wetting and Drying (AWD): A water management technique in rice cultivation that involves periodically drying and re-flooding fields to reduce methane emissions.
• Methane: A potent greenhouse gas, with 28 times the global warming potential of carbon dioxide over 100 years, produced in anaerobic conditions like flooded rice fields.
• Carbon Credits: Tradable permits representing the removal or reduction of greenhouse gas emissions, allowing companies to offset their carbon footprint.
