A new scientific publication, supported by REST-COAST and authored by Marion Dolivet-Maréchal (INRAE), has been published in the Earth Systems and Environment journal.

“The Dual Climate Role of Seagrass Meadows in Arcachon Bay” shows how seagrass ecosystems help store carbon and support climate regulation, while also releasing some greenhouse gases. The study finds that, although these emissions reduce part of the benefit, seagrass meadows still provide a much stronger overall climate benefit than areas without vegetation.

This is one of the first studies in Europe to measure both carbon storage and greenhouse gas emissions directly in seagrass meadows, helping to better understand their real climate impact. The results highlight the importance of protecting and restoring seagrass habitats, which also support biodiversity, fish populations and coastal protection.
