海藻養殖は炭素固定による気候緩和策として期待される一方、半閉鎖的な沿岸域では富栄養化や酸性化などの環境リスクも引き起こす。本レビューは、これらの光と影を総合的に評価し、水交換特性や底層-表層結合を考慮した立地ゾーニングを含む適応的管理の枠組みを提案する。
English
Seaweed farming is promoted for climate mitigation via carbon sequestration, but it poses risks like eutrophication and acidification in semi-enclosed coastal areas. This review synthesizes both benefits and risks, emphasizing the need for site-specific hydrodynamic assessment and adaptive management, including hydrodynamically guided zoning.

In the global GX context
Globally, seaweed farming is gaining traction as a nature-based solution for carbon dioxide removal (CDR). This paper highlights the paradox of ecological risks that could undermine climate benefits, urging comprehensive evaluation frameworks that incorporate hydrodynamics, relevant for international blue carbon initiatives and climate policy.
👥 読者別の含意
🔬研究者:Researchers in blue carbon, marine biogeochemistry, and climate mitigation should consider the trade-offs and need for integrated assessment frameworks.
🏢実務担当者:Coastal managers and aquaculture operators can use the insights for site selection and environmental impact assessments, balancing climate goals with ecosystem resilience.
🏛政策担当者:Policymakers promoting marine CDR should incorporate risk assessments and adaptive management, including hydrodynamically guided zoning, to ensure sustainable outcomes.
📄 Abstract（原文）
Seaweed farming is increasingly promoted as a nature-based solution for marine carbon dioxide removal (mCDR), offering the dual promise of climate mitigation and ecosystem enhancement. However, here we highlight a fundamental paradox: while macroalgae cultivation can significantly boost carbon sequestration and support biodiversity, it also introduces site-specific ecological risks—most notably eutrophication, hypoxia, and acidification—particularly in semi-enclosed coastal systems with limited water exchange. We synthesize current understanding of both the positive and negative impacts of large-scale macroalgae farming, examining pathways of carbon uptake, storage, and export alongside biogeochemical and food web disruptions. Critically, we identify the overlooked roles of hydrodynamic conditions and benthic-pelagic coupling in mediating ecological outcomes. To ensure that macroalgae aquaculture contributes effectively to climate goals while safeguarding coastal ecosystem resilience, we call for the development of a targeted and comprehensive evaluation framework capable of accurately assessing its impacts on adjacent waters. Such a framework should incorporate site-specific water-exchange characteristics and biogeochemical vulnerability, thereby enabling more informed and adaptive management strategies—including hydrodynamically guided site zoning—to support sustainable, long-term ecosystem benefits.
