ABSTRACT The Indian Ocean is home to some of the most extensive coastal blue carbon ecosystems on the planet. Together, the nations within and surrounding this ocean basin contain approximately 50% (an estimated 76,275 km2) of the world’s mangrove forests and a large, but unknown, proportion of its seagrass meadows. The nations of the Indian Ocean have an opportunity to be world leaders in restoration and protection of these ecosystems, which can help mitigate climate change, enhance livelihoods and protect shorelines from erosion and storm damage. Already, Indian Ocean nations are showing leadership by acknowledging blue carbon ecosystems in their Nationally Determined Contributions, and by championing efforts to establish some of the largest blue carbon restoration projects globally. However, more can be done. We outline a research agenda that will pave the way for effective evidence-based policy in the Indian Ocean, by reducing uncertainty and providing the tools and knowledge needed.

印度洋中的蓝碳：审查和研究议程

摘要 印度洋拥有地球上一些最广泛的沿海蓝碳生态系统。这个洋盆内和周围的国家加起来约占世界红树林的 50%（估计 76,275 平方公里）和一大片但未知的海草草甸。印度洋国家有机会成为恢复和保护这些生态系统的世界领导者，这有助于缓解气候变化、改善生计并保护海岸线免受侵蚀和风暴破坏。印度洋国家已经通过在其国家自主贡献中承认蓝碳生态系统，并通过支持在全球建立一些最大的蓝碳恢复项目的努力来展示领导力。但是，还可以做更多的事情。
