韓国中部の放棄水田湿地（APWs）6地点で土壌・バイオマス炭素を定量化。IPCCガイドラインに基づき土壌有機炭素貯留量（SOCS）を推定し、平均61.20 kg/m2と森林土壌の8.5～40倍の値を示した。2000年から2021年にかけて炭素吸収量は増加傾向にあり、APWsが持続可能な土地管理と気候変動緩和に寄与する可能性を示唆する。
English
This study quantified soil and biomass carbon in six abandoned paddy wetlands (APWs) in central South Korea, following IPCC GPG-LULUCF guidelines. Mean soil organic carbon storage (SOCS) was 61.20 kg/m2, 8.5-40 times higher than reference forest soils. Carbon absorption increased from 20.45 tCO2/ha in 2000 to 38.14 tCO2/ha in 2021, suggesting APWs contribute to sustainable land management and climate mitigation.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では耕作放棄地の増加が課題であり、放棄水田を炭素吸収源として評価する手法は、農地の持続可能な管理やJ-クレジット制度への応用可能性を示す。国内の土壌炭素算定方法と比較する際の参考となる。
In the global GX context
This study provides empirical evidence on carbon sequestration in abandoned agricultural wetlands, relevant to global land-use change and climate mitigation policies. It complements IPCC guidelines and offers region-specific data that can inform sustainable land management strategies and carbon accounting frameworks such as those under the Paris Agreement.

📄 Abstract（原文）
Abandoned paddy wetlands (APWs) develop after rice cultivation ceases and may support carbon sequestration, soil conservation, and sustainable management of abandoned agricultural land. This study quantified soil and biomass carbon in six reference APWs in the central region of the Republic of Korea. Following the Intergovernmental Panel on Climate Change (IPCC) Good Practice Guidance for Land Use, Land Use Change and Forestry (GPG-LULUCF), soil samples were collected to a depth of 30 cm to estimate soil organic matter (OM), soil organic carbon (SOC), and soil organic carbon storage per unit area (SOCS). Land cover-based carbon absorption was evaluated within 300 m hydro-ecological impact zones for 2000, 2013, and 2021, and biomass carbon was estimated for woody, herbaceous, and mixed communities using field measurements and drone LiDAR-derived vegetation structure. The mean OM and SOC contents were 33.7 and 19.54 g/kg, respectively. The corrected mean SOCS was 61.20 ± 22.28 kg/m2 (unadjusted mean: 67.97 kg/m2), approximately 8.5–40 times the reference values reported for South Korean forest soils and urban parks. The mapped mean carbon absorption was 20.45 tCO2/ha in 2000, 35.30 tCO2/ha in 2013, and 38.14 tCO2/ha in 2021. Because only three mapped years were analyzed, these values describe observed differences and do not establish a continuous temporal trajectory or a stable plateau. The findings suggest that APWs may contribute to sustainable land management, wetland restoration, soil conservation, and climate-change mitigation through carbon retention in soils and vegetation. These field data provide region-specific evidence for evaluating sustainable management strategies and complementing broader-scale soil–vegetation carbon models.
