汇聚蓝碳力量 共绘海洋蓝图

Core Insights - The recent 2025 Blue Carbon International Symposium and West Pacific Blue Carbon Ecosystem Restoration Workshop highlighted the importance of blue carbon ecosystems, particularly mangroves, in climate change mitigation and ecological restoration efforts [1] Group 1: Marine Carbon Sequestration - The ocean is identified as the largest active carbon sink with significant negative emission potential. A new negative emission strategy, BCMS, integrates four carbon pumps to maximize ocean carbon storage [3] - The "International Grand Science Plan for Marine Negative Emissions," initiated by Chinese scientists, has gained international recognition with participation from over 80 research teams across 35 countries [3] Group 2: Importance of Mangrove Restoration - Tropical tidal wetland forests, such as mangroves, are crucial for carbon storage and biodiversity. Their degradation transforms them from carbon sinks to significant emission sources, necessitating restoration efforts [5] - Scientific approaches to mangrove restoration should prioritize ecosystem-based methods, focusing on ecological characteristics, restoration goals, and suitable species configurations [5] Group 3: Global Research and Monitoring Initiatives - Research on blue carbon ecosystems has rapidly developed since 2010, with a focus on coastal wetland carbon sinks and greenhouse gas emissions. However, Southeast Asia's research on mangroves remains limited [6] - International cooperation has been initiated for mangrove monitoring, utilizing remote sensing data to support policy-making and enhance data comparability [6] Group 4: National and Regional Case Studies - Malaysia emphasizes the protection of existing mangroves over post-damage restoration, implementing various protective measures and community involvement in restoration efforts [11][13] - Thailand has integrated mangrove carbon sinks into climate policy, allowing community and corporate partnerships to develop carbon credit projects, with 90% of the revenue benefiting the participants [17] Group 5: Funding and Investment Strategies - Sustainable funding is essential for large-scale mangrove restoration, with blue finance tools like blue bonds and carbon credits being explored to support ecological restoration efforts [19] - The establishment of a long-term financing system for mangrove and coastal wetland restoration is crucial, requiring collaboration among government, financial, and social institutions [19] Group 6: Challenges and Future Directions - Indonesia faces challenges in achieving its mangrove restoration goals due to ecological pressures and the need for reliable scientific assessments to guide restoration efforts [21] - Cambodia's mangrove restoration efforts are hindered by illegal logging and land use changes, necessitating enhanced cooperation and community engagement [39][41]
