Blue carbon ecosystems, including mostly salt marshes, mangroves, seagrasses, tidal forests and mudflats, rank among the most carbon-dense ecosystems on Earth. They provide nature-based solutions essential to mitigate residual anthropogenic carbon emissions, while also delivering co-benefits such as biodiversity support or coastal protection. However, their resilience and capacity to sustain these functions are increasingly threatened by climate change and human pressures. To safeguard their role, it is essential to better understand their carbon cycle—particularly the feedback loops between soil and plants, the exchanges of carbon among the atmosphere, soil, and water, but also how human activities, vegetation, and carbon processes interact.
This session seeks to bring together scientists from multiple disciplines, including biogeochemists, ecologists, geographers, geologists, social scientists, biologists, alongside environmental managers.
By bridging perspectives across the natural and social sciences, the session aims to showcase pioneering research that i) advances understanding processes related to biomass and carbon in blue carbon ecosystems under current and future environmental conditions; and ii) spotlights effective management, conservation, and restoration practices to sustain or enhance carbon sequestration and broader ecosystem services, coupling the ecological functioning with social needs. Through this integration, the session will contribute to the goals of the United Nations Decade for Ocean Sciences, with co-convenorship from the Decade Programme for Blue Carbon in the Global Ocean.
