農業由来のGHGは世界排出の21〜37%を占め、気候変動の影響も強く受ける。本レビューは109研究を基に、保全耕起やアグロフォレストリー等の自然基盤ソリューション（NbS）の炭素隔離ポテンシャルを0.4〜2.8 Mg C ha-1 yr-1と評価し、土壌有機炭素を15〜50%高めうると示す。土壌健康指標の重要性と、EU自然回復法・土壌モニタリング指令の政策動向を整理し、長期・多地点研究と標準化モニタリングの必要性を訴える。
English
Agriculture contributes 21-37% of global GHG emissions while being highly climate-vulnerable. Reviewing 109 studies, this paper assesses nature-based solutions (NbS) such as conservation tillage and agroforestry, finding carbon sequestration of 0.4-2.8 Mg C ha-1 yr-1 and soil organic carbon gains of 15-50% over conventional monocropping. It highlights soil health indicators and evolving EU policy (Nature Restoration Law, Soil Monitoring Directive), calling for long-term, multi-site studies and standardized monitoring.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では農林業の脱炭素とJ-クレジット（農地土壌炭素貯留）の制度設計が進む。本レビューは土壌炭素測定の標準化と政策枠組みの必要性を示し、国内の農業由来クレジットやSSBJのScope3・土地利用変化開示を検討する企業・自治体に示唆を与える。
In the global GX context
Globally, NbS are increasingly embedded in climate policy (EU Nature Restoration Law, CSRD/ESRS E1-E4) and voluntary carbon markets. This review synthesizes sequestration rates and soil health metrics, offering evidence for standardizing agricultural carbon accounting and for corporate nature-related disclosure under TNFD/ISSB.
👥 読者別の含意
🔬研究者:土壌炭素隔離ポテンシャルの統合的レビューとして、NbSの効果測定指標と政策評価の枠組みを提供する。
🏢実務担当者:農業・食品企業がScope3や土地利用変化の削減目標を設定する際、アグロフォレストリー等の定量的根拠として活用できる。
🏛政策担当者:EUの土壌モニタリング指令等を参照し、国内の農地炭素貯留制度やJ-クレジット設計に標準化モニタリングの視点を取り入れるべき。
📄 Abstract（原文）
Greenhouse gas emissions from agriculture are estimated to be approximately 21-37% of global emissions, while agriculture is severely impacted by a changing climate. Use of Nature-based Solutions (NbS) can be cost-effective and offers multiple advantages for addressing these issues. This paper reviews existing knowledge and evidence found within soil science, agronomy, forestry, and environmental policy to evaluate NbS for the mitigation of greenhouse gas emissions and enhancement of carbon sequestration. Drawing from 109 reviewed studies, we evaluated the carbon sequestration potential of different types of NbS, which range from 0.4 to 2.8 Mg C ha-1 yr-1 (or 1.5 to 10.3 Mg CO₂-eq ha-1 yr-1), and depends on the type of system, the species of tree, the soil, and the climate. We study the different types of NbS, such as conservation tillage and agroforestry practices, as examples of how they can potentially enhance soil organic carbon (SOC) by 15-50% compared to conventional monocropping practices. We study the neglected yet crucial role of soil health indicators physical, chemical, and biological in measuring the effectiveness of NbS. We evaluate the policy frameworks of the EU Nature Restoration Law and the proposed Soil Monitoring Directive and illustrate how they are evolving to address NbS. Although they are quite limited, NbS are useful tools for development and implementation of climate change mitigation actions. We believe that the full potential of NbS can be realized with long-term, multi-site studies along with standardized monitoring, integrated technologies, strong governance systems, and community involvement.
