ブラジル大西洋岸森林の再生林における炭素蓄積をリモートセンシングで分析。森林の連結性が高いほど炭素蓄積速度が43～69%向上し、特に西部・海岸部では3倍以上の差があった。2020年時点の二次林を完全保護すれば2030年までに132 Tg Cの追加蓄積が可能と推定。連結性を考慮した保全政策の重要性を示す。

Using remote sensing, this study analyzes aboveground carbon accumulation in regenerating Brazilian Atlantic Forests. Forest connectivity increases carbon accumulation rates by 43–69%, with highly connected landscapes accumulating over three times more carbon than fragmented ones. Full protection of secondary forests from 2020 could boost stocks by 35% (132 Tg C) by 2030. Results highlight the need for conservation policies that enhance spatial connectivity to maximize climate mitigation.

日本のGX文脈において
本論文はブラジルが対象だが、日本の森林再生や炭素吸収源対策にも示唆を与える。特に、森林の連結性が炭素蓄積に与える影響は、日本の里山や二次林管理においても考慮すべき要素であり、SSBJやカーボンクレジット制度における森林由来クレジットの評価に活用できる可能性がある。
In the global GX context
This paper provides strong empirical evidence linking forest connectivity to carbon sequestration in tropical forests, relevant to global REDD+ and nature-based solutions frameworks. It underscores the importance of landscape-level conservation for climate mitigation, aligning with the Kunming-Montreal Global Biodiversity Framework and ISSB's nature-related disclosures. The findings can inform carbon accounting methodologies for forest regeneration projects worldwide.

📄 Abstract（原文）
Abstract Understanding the fate of carbon stocks in human-modified tropical landscapes is critical for mitigating climate change. Yet quantifying the impacts of landscape connectivity on the potential of regrowing forests to sequester carbon remains underrepresented. Using remote sensing and a space-for-time substitution approach, we analyzed aboveground carbon accumulation across the Brazilian Atlantic Forest. Forest connectivity emerged as a key determinant of carbon gains, with accumulation rates increasing by 43%–69% from fragmented to highly connected landscapes. In the western and coastline region, highly connected forests accumulated over three times more carbon (3.03 ± 0.81 vs. 0.93 ± 0.34 Mg C ha⁻¹ yr⁻¹) than those in low-connectivity areas. We modeled carbon stocks and found that full protection of secondary forests as of 2020 could increase stocks by 35% (132 Tg C) by 2030. Our results highlight the importance of protecting both old-growth and secondary forests while enhancing connectivity through targeted restoration. Strengthening conservation policies that integrate spatial connectivity is essential to maximizing the climate mitigation potential of tropical forests.
