Comment Preprint - Seascape carbon accounting boundary.pdf

Author Preprint of COMMENT article "<b>How does your carbon flow? Adopting a seascape boundary for coastal habitats overcomes common challenges for blue carbon accounting</b>"<b>Abstract:</b> This commentary advocates for a shift from single-habitat to seascape-scale carbon accounting in coastal ecosystems. By recognizing the dynamic flow of organic carbon across interconnected habitats, a seascape approach better captures climate mitigation benefits. It addresses challenges in credit allocation, allochthonous carbon treatment, and ecosystem connectivity, offering a more holistic framework for blue carbon policy, restoration, and market mechanisms aligned with nature-based solutions and biodiversity objectives.
