中国科学家牵头发布滨海湿地碳汇倡议推动构建陆海联动碳汇合作体系

Core Viewpoint - The "Coastal Wetland Carbon Sink Initiative" was presented at the 12th International Ecological Society Wetland Conference, highlighting the importance of coastal wetlands in carbon sequestration and the need for global collaboration in research and technology sharing [1][2]. Group 1: Initiative Overview - The initiative proposes five action frameworks to guide global research and collaboration on coastal wetland carbon sinks, including promoting scientific cooperation, establishing a global alliance, sharing technology, integrating local wisdom, and implementing demonstration projects [2]. - A total of 32 scientists from 15 countries signed a support document for the initiative, marking a significant step in building a global collaboration system for coastal wetland carbon sink research [2]. Group 2: Conference Insights - The conference focused on key issues such as climate change, sea level rise, and nutrient loading, discussing strategies to enhance the carbon sink functions of coastal wetlands [3]. - Experts emphasized the challenges faced in protecting coastal wetlands as critical "blue carbon sinks" and the need to overcome technological bottlenecks in land-sea interactions [3]. Group 3: ONCE Plan Background - The ONCE Plan, initiated by Academician Jiao Nianzhi in 2019, aims to explore ocean negative emission mechanisms through international collaboration and has attracted participation from 33 countries and 79 research institutions by 2024 [4]. - The plan is integrated into the UNESCO "Decade of Ocean Science for Sustainable Development" action plan, enhancing China's international influence in marine negative emissions and ecological protection [4].
