ウガンダの有機廃棄物管理戦略をステークホルダー参加型で策定し、複数の介入により2035年までに年間最大130万トンのCO2換算メタン排出を回避できると推定。堆肥やバイオガス生産による食料安全保障とエネルギーアクセス向上の便益も示した。
English
This study develops a National Organic Waste Management Strategy for Uganda through stakeholder engagement and modeling. It shows that combining interventions could avoid up to 1.3 million tonnes CO2-equivalent methane emissions annually by 2035, while producing compost for maize and biogas for cooking, enhancing climate resilience, food security, and energy access.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では廃棄物分野のメタン削減がカーボンニュートラル戦略に組み込まれており、自治体や企業の廃棄物管理計画に参考となる。特に、ステークホルダー参加型の戦略策定プロセスは、日本の地域循環共生圏の取り組みに示唆を与える。
In the global GX context
Globally, this study contributes to the growing literature on methane mitigation in the waste sector, aligning with the Global Methane Pledge and IPCC guidance. It provides a model for inclusive, co-designed national strategies that integrate climate, food, and energy goals, relevant for developing countries and international climate finance.

📄 Abstract（原文）
Abstract Environmentally sound organic waste management and landfill diversion can substantially reduce methane emissions and contribute to climate change mitigation. However, effective waste management is also critical for protecting public health, environmental quality, and urban sustainability extending well beyond climate objectives. Here we developed an inclusive National Organic Waste Management Strategy for Uganda through stakeholder engagement and co-design workshops involving local communities, civil society, academia and government representatives, combined with modeling of organic waste treatment pathways and associated co-benefits. The resulting strategy reflects local constraints and development needs while supporting resource recovery and energy generation. Here we show that combining multiple organic waste management interventions could avoid up to 1.3 million tonnes of carbon dioxide equivalent methane emissions annually by 2035, produce sufficient compost to fertilize approximately 271102 hectares of maize, and generate enough biogas to support the preparation of about 628000 meals each year, strengthening climate resilience, food security and energy access.
