Workshop on Quantification and Visualization of CH4 Emissions in Agriculture and Carbon Credit Development through Alternative Wetting and Drying

Launched in 2023, the APO COE on Climate-smart Agriculture (CSA), hosted by the National Agriculture and Food Research Organization (NARO), Japan, set among its first objectives the visualization of agricultural GHG emissions and the strengthening of APO members’ capacity to design and implement effective mitigation strategies. In 2024, efforts focused on CO2 through soil carbon sequestration modeling, laying the foundation for regional capacity building. In 2025, activities expanded to N2O emissions through meta-analysis and quantification while introducing carbon credit methodologies for biochar. Building on these initiatives, the 2026 program focuses on CH4 emissions from rice cultivation, a major source of agricultural GHG emissions in the region, while strengthening members’ capacity to quantify, analyze, and visualize emissions and assess mitigation outcomes. The workshop in Tsukuba will also address emerging needs and practical challenges in developing high-integrity carbon credits through AWD implementation, including data requirements, baseline setting, monitoring, reporting, and verification (MRV), and effective communication of results.
