本研究は、世界の土壌有機炭素（SOC）データを収集・分析し、気候変動や人間活動がSOCプールに与える影響を評価。粒子状有機炭素（POC）は鉱物結合有機炭素（MAOC）よりも管理や気候変動に敏感で、SOC動態の主要な駆動要因であることを示した。将来予測では、2060～2080年にかけて気候圧力によりSOCが大幅に減少し、2023年の人為起源CO2排出量の0.7～1.2倍に相当する損失が生じる可能性を警告している。
English
This study compiles a global dataset of soil organic carbon (SOC) and analyzes the impacts of climate change and human activities on SOC pools. Particulate organic carbon (POC) is more sensitive to management and climate change than mineral-associated organic carbon (MAOC), playing a larger role in SOC dynamics. Projections indicate significant SOC loss from 2060-2080, equivalent to 0.7-1.2 times 2023 anthropogenic CO2 emissions, underscoring the urgency to protect carbon reservoirs.

📄 Abstract（原文）
Soil organic carbon (SOC) is key to sustaining agricultural productivity and safeguarding ecosystem services amid challenges from human activities and climate change. SOC embodies a continuum from coarse remnants of plant matter (particulate organic carbon, POC) to resilient mineral-associated organic carbon (MAOC), with each component responding uniquely to environmental factors, making assessment crucial. In our study, we compiled an extensive global dataset comprising 6,668 SOC data points, alongside 3,088 POC and MAOC observations. SOC stock difference is more closely associated with POC. POC shows stronger sensitivity to management and climate change than MAOC, indicating its potentially larger role in driving SOC dynamics under anthropogenic activities and climate change. Random Forest models unveil the strong influence of soil type on the spatial distribution and relative proportions of SOC pools, highlighting its pivotal role in shaping soil carbon composition. Our projections draw a sobering picture: mounting climate pressures lead to troubling decline in global SOC concentration. From 2060 to 2080, SOC loss under various climate scenarios is estimated to reach 0.7-1.2 times the CO<sub>2</sub> emissions from anthropogenic sources recorded in 2023 (40.9 Pg). These findings emphasize the urgent need to safeguard carbon reservoirs from the threats of human impact and climate change.
