マングローブ、塩性湿地、海草藻場などのブルーカーボン生態系（BCE）はCO2を長期間隔離するが、気候変動や人為的劣化によりその機能が脅かされている。保全・回復が自然ベースの気候対策として重要であり、海洋ジオエンジニアリングは不確実性が高いため補完的と位置づけられる。

Blue carbon ecosystems (BCEs) like mangroves, salt marshes, and seagrasses sequester CO2 long-term but face threats from climate change and degradation. Conservation and restoration are vital natural climate solutions, while marine geoengineering remains uncertain and complementary.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では、ブルーカーボン生態系（藻場・干潟）の保全が「ブルーカーボン」として注目され、Jブルークレジット制度などが整備されつつある。本論文は、こうした生態系の気候変動緩和機能を整理し、政策や企業の自然関連開示（TNFD）への示唆を与える。
In the global GX context
Globally, blue carbon ecosystems are increasingly recognized in climate policy and corporate sustainability frameworks (e.g., TNFD, carbon markets). This paper provides a comprehensive overview of their sequestration potential and threats, supporting conservation and restoration as climate solutions.

📄 Abstract（原文）
Blue carbon ecosystems (BCEs) such as mangroves, salt marshes, and seagrasses, sequester significant amounts of CO 2 from the atmosphere. These ecosystems capture and store carbon in biomass and sediments over long periods. Other marine ecosystems, including the open ocean, kelp forests, bivalve reefs, and coral reefs, have been excluded from the BCEs, but they have the potential to serve as crucial blue carbon sinks or to support adjacent BCEs. Climate change, however, poses severe threats to these ecosystems. Rising sea levels, increasing temperatures, and ocean acidification can lead to habitat loss, reduced biodiversity, and impaired carbon sequestration capacity. Consequently, anthropogenic degradation of BCEs releases stored carbon back into the atmosphere, exacerbating climate change. Despite these challenges, BCEs represent important natural climate solutions because conserving and restoring these ecosystems can enhance carbon storage, support biodiversity, and provide additional benefits for local communities. Active restoration, protection, and effective management strategies can increase ecosystem resilience and maintain long-term carbon capacity. Emerging marine geoengineering approaches, including enhanced weathering, iron fertilization, and artificial upwelling have been proposed as potential methods to increase ocean carbon storage; however, these approaches remain largely experimental and face substantial uncertainties regarding scalability, environmental impacts, carbon permanence, and feasibility. Therefore, future climate mitigation strategies should prioritize conservation and restoration of BCEs while continuing to evaluate emerging technologies as potential complementary approaches to enhance marine carbon storage.
