Summary: Alternate Wetting and Drying can reduce methane emissions from rice cultivation. Combined with biochar and dMRV, it can become a scalable climate-smart agriculture pathway. This resource is designed for partners, customers, project developers, investors, and sustainability teams evaluating biochar and climate-smart agriculture opportunities.
What AWD is
Alternate Wetting and Drying is a water management practice used in rice cultivation. Instead of keeping fields continuously flooded, farmers allow water levels to drop during certain crop stages before re-flooding. This changes soil oxygen conditions and can reduce methane formation.
Why rice methane matters
Flooded rice fields can produce methane when organic matter decomposes under anaerobic conditions. Methane has a strong warming effect, so practices that reduce methane while maintaining yields are important for climate-smart agriculture.
How carbon credits may be generated
AWD projects can potentially generate carbon credits when methane reductions are measured against a credible baseline and verified under an accepted methodology. The project must demonstrate that the water management change occurred, that emissions were reduced, and that farmers followed the required practice.
Where biochar fits
Biochar can support AWD by improving soil structure, water retention, nutrient retention, and microbial habitat. In some systems, biochar may help make drying cycles less stressful for crops while supporting improved fertilizer efficiency.
Why dMRV is important
AWD carbon projects require reliable field data: farms, fields, crop cycles, irrigation events, water depth, farmer participation, photos, audit logs, and documentation. Digital MRV can reduce the cost and complexity of managing thousands of hectares.
SAWA’s approach is practical: connect regional biomass residues with production infrastructure, soil applications, carbon accounting, and long-term partnerships.
How this connects to SAWA
For SAWA, this topic is part of a broader platform: biochar production, soil restoration, verified carbon removal, project development, and digital reporting. Visitors interested in commercial deployment can explore SAWA projects or contact the team about partnerships.
Partner with SAWA
