ケニアのラム諸島の海草藻場において、土壌有機炭素（SOC）貯蔵量を調査。海洋保護区（MPA）や地域管理海域（LMMA）は非管理地域より高いSOCを示したが、堆積物の質や種構成などの環境要因も影響。初の現地測定データを提供し、ブルーカーボン保全戦略へのLMMAの可能性を示唆。
English
This study provides the first field-based estimates of soil organic carbon stocks in seagrass meadows of Lamu, Kenya, comparing Marine Protected Areas, Locally Managed Marine Areas, and unmanaged sites. SOC stocks were higher in managed areas, but variability was strongly linked to sediment type and seagrass species composition. The findings highlight the potential of community-based management for blue carbon conservation.

日本のGX文脈において
日本においてもブルーカーボン生態系（海草藻場、マングローブ、干潟）はカーボンクレジット（Jブルークレジット）やNDC達成に貢献する。本論文はLMMAのような地域管理の有効性を示唆し、日本の漁協主体の藻場保全政策に示唆を与える。
In the global GX context
This empirical study from Kenya provides evidence that locally managed marine areas can achieve carbon storage levels comparable to formal protected areas. It underscores the role of sediment characteristics and species composition in carbon stock variability, supporting inclusion of community-managed areas in global blue carbon crediting frameworks.

📄 Abstract（原文）
Seagrass ecosystems play a crucial role in coastal carbon dynamics, yet their contribution to soil organic carbon (SOC) storage is underexplored in many areas and especially in African waters. This study assessed seagrass cover, species composition, and SOC stocks in the Lamu Archipelago, Kenya, comparing Marine Protected Areas (MPAs), Locally Managed Marine Areas (LMMAs), and unmanaged sites. Additionally, it investigated the relationships between management stratgeies and pertinent physical and chemical parameters. SOC was measured using the Loss on Ignition method and expressed as Mg C ha⁻¹. SOC stocks were higher in MPAs (89.16 ± 30.88 Mg C ha⁻¹) than in unmanaged areas, while SOC stocks in LMMAs were comparable to those in MPAs. While the MPA was associated with higher SOC stocks, these patterns may also reflect underlying environmental differences among sites, including sediment texture. SOC variability was strongly associated with sediment type, canopy cover, and disturbance intensity, with fine-grained sediments, particularly clay, linked to enhanced carbon retention. Higher SOC stocks co-occurred with the presence of large, persistent seagrass species such as Thalassodendron ciliatum and Enhalus acoroides in managed areas. This study provides the first field-based SOC estimates for Lamu's seagrass meadows, highlighting the potential of LMMAs within broader blue carbon conservation strategies.
