カリムンジャワ諸島の4島を対象に、2000〜2022年のマングローブ土地被覆変化を衛星画像で分析し、炭素ストック変化に基づくCO₂排出量を推計した。カリムンジャワ島・ケムジャン島で排出量が最大となり、2042年までの予測ではケムジャン・ニャムク・パランの各島で炭素損失が拡大する。地形・人為圧力・ガバナンスが動態を規定することを示し、地域固有の適応的管理の必要性を訴える。
English
Satellite imagery tracks mangrove land-cover change across four Karimunjawa islands from 2000–2022, with carbon-stock-based CO₂ emission estimates. Karimunjawa and Kemujan show the largest extents but also the highest emissions from land conversion, while projections to 2042 indicate growing carbon loss on Kemujan, Nyamuk, and Parang. Geomorphology, anthropogenic pressure, and governance shape these divergent trajectories, underscoring the need for site-specific adaptive management.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本企業のブルーカーボン・自然資本開示（TNFD対応やクレジット活用）に関心のある読者にとって、小島嶼マングローブの炭素収支推計手法は参考になる。ただしSSBJ・有報開示との直接の接続は薄い。
In the global GX context
Adds empirical blue-carbon evidence to the growing nature/ biodiversity disclosure agenda (TNFD, ISSB nature-related work), showing how land-cover-driven carbon stock loss can be quantified at island scale. Useful as a methodological reference for ecosystem carbon accounting rather than for corporate disclosure frameworks directly.

📄 Abstract（原文）
Mangrove ecosystems play a critical role in coastal resilience and long-term carbon storage, yet their spatiotemporal dynamics in small island systems remain poorly understood. This study analyzes mangrove land-cover change from 2000 to 2022 across four major islands in the Karimunjawa Archipelago (Karimunjawa, Kemujan, Parang, and Nyamuk) and projects future trends to 2042. Using multi-temporal satellite imagery and carbon stock–based estimates of CO₂ emissions resulting from mangrove land-cover change, the results reveal heterogeneous trajectories of degradation and recovery. Estimated CO₂ emissions were calculated by multiplying the change in carbon stock, the molecular weight conversion factor from carbon (12/44), and the area of mangrove land-cover change (ha). In 2015, Karimunjawa and Kemujan maintain the largest mangrove extents but are also associated with the highest estimated CO₂ emissions, reaching 273,899.30 t CO₂ ha-¹ as a consequence of land-use conversion, whereas Nyamuk exhibits relatively stable dynamics with localized carbon stock loss corresponding to estimated CO₂ emissions of up to 1,037.13 t CO₂ ha-¹, and Parang shows persistent decline with estimated CO₂ emissions of up to 587.97 t CO₂ ha-¹. Future projections indicate increasing carbon stock loss and associated estimated CO₂ emissions toward 2042, particularly on Kemujan, Nyamuk, and Parang, reaching 574,188.40, 2,551.95, and 1,953.84 t CO₂ ha-¹, respectively, highlighting growing risks to coastal ecosystem integrity and climate change mitigation efforts. These findings underscore the influence of geomorphology, anthropogenic pressure, and governance in shaping mangrove dynamics on small islands. Integrated, site-specific, and adaptive management strategies are therefore essential to conserve mangrove carbon stocks, minimize carbon losses associated with land-cover change, and strengthen coastal resilience in the Karimunjawa Archipelago.
