ナイジェリアのマングローブ・海草・干潟などのブルーカーボン生態系の炭素隔離能力と、沿岸開発・石油開発・汚染による劣化傾向をレビュー。生態系保全が気候緩和・漁業・生計に資する一方、海草マッピングや堆積物炭素量、標準化MRV、 tenureのデータギャップを指摘。NDC・LT-LEDSへの統合、FPICに基づくコミュニティ主導の回復、ブレンドファイナンス、法的保護を提言。
English
This review examines the carbon sequestration potential of Nigeria's coastal blue carbon ecosystems (mangroves, seagrasses, wetlands) and the drivers of their degradation from development, oil exploration, and climate pressures. It links ecosystem change to livelihoods and food security, and proposes integrating blue carbon into Nigeria's NDCs and LT-LEDS through participatory governance, blended finance, and standardized MRV. Persistent data gaps in seagrass mapping and sediment carbon stocks are highlighted.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本はブルーカーボン（藻場・干潟）をJ-クレジットやブルーカーボン推進に活用しており、ナイジェリアのMRV・NDC統合・地域主導回復の議論は、日本の沿岸炭素クレジット制度や国際協力の設計に示唆を与える。
In the global GX context
As global disclosure frameworks (ISSB, TCFD) increasingly touch nature and biodiversity, this paper illustrates how blue carbon can be integrated into national climate policy (NDCs, LT-LEDS) and MRV systems, offering a Global South perspective on carbon accounting and governance gaps relevant to international climate finance.

📄 Abstract（原文）
Coastal vegetated ecosystems particularly mangroves, seagrasses, and intertidal wetlands are widely recognized as “blue carbon” systems due to their ability to sequester and store large volumes of carbon in biomass and sediments while providing vital ecosystem services that support coastal livelihoods and resilience. Along Nigeria’s coastline, including the Niger Delta, Lagos lagoon complexes, and several estuaries, mangrove forests and recorded seagrass habitats play key roles in carbon storage and socio-economic sustenance. However, these ecosystems are under severe threat from coastal development, oil and gas exploration, pollution, dredging, aquaculture expansion, and climate-related pressures such as sea-level rise and intensifying storms. This paper reviews the carbon sequestration potential of Nigeria’s coastal ecosystems, documents observed trends and drivers of degradation, assesses links between ecosystem change, livelihoods, and food security, and explores governance options for integrating blue carbon into Nigeria’s blue economy and climate policy. Evidence from regional and global syntheses, Nigeria specific studies, and policy frameworks shows that conserving and restoring coastal ecosystems can deliver climate mitigation, shoreline protection, fisheries enhancement, and livelihood benefits if grounded in participatory governance and safeguards. Yet, significant data gaps persist, particularly in seagrass mapping, sediment carbon stocks, standardized MRV (measurement, reporting, verification), and tenure clarity. We recommend a national agenda emphasizing: (i) blue carbon inventories and validation, (ii) inclusion in NDCs and LT-LEDS, (iii) community-led restoration with FPIC, (iv) blended finance and MRV capacity building, and (v) legal safeguards for equity. Advancing these steps would align Nigeria’s blue economy with climate and wellbeing goals.
