In May 2023, Fakhraee et al. published a research article titled “Ocean alkalinity enhancement through restoration of blue carbon ecosystems” in Nature Sustainability. In this essay, we discuss an assessment of the costs of restoring and maintaining the mangrove-seagrass ecosystems indicated in the article.

Con người tự hào đứng đầu chuỗi thức ăn. Tự hào hơn nữa con người có trí khôn trác tuyệt để tạo ra cả hệ tiêu chuẩn và gọi việc ăn của mình là giàu tính “đạo đức” theo cách diễn đạt của Paul Valéry trong Tel Quel (1941).

As the climate crisis intensifies, coastal ecosystems—such as mangroves, tidal marshes, and seagrass meadows—are gaining recognition for their role in sequestering “blue carbon” (BC)...

Climate change, driven by greenhouse gas emissions, poses a significant threat to life and livelihoods globally. China, the world's largest carbon emitter, yet has a significant area of coastal blue carbon (CBC) ecosystems covering mangroves, salt marshes, and seagrass beds which are vital for carbon sequestration. This study assesses the current state of these ecosystems, evaluates Chinese policies for CBC conservation, appraise Chinese blue carbon (BC) market development and compares them with international efforts. The findings highlight inadequate conservation measures (...) and a lack of specific laws and enforcement for BC protection in China. The BC market suffers from unclear responsibilities, dampening corporate participation. Recommendations include hastening legal frameworks, bolstering enforcement, defining BC rights and ownership, and involving the public in BC initiatives. A SWOT analysis underscores the need for urgent action to bolster China's CBC ecosystems and market development. (shrink)
