日本語

本レビューは、土壌有機炭素（SOC）隔離が温室効果ガス削減と農業の持続可能性に果たす役割を包括的に評価する。保全農業、アグロフォレストリー、被覆作物、バイオ炭などの管理手法により、年間ヘクタールあたり0.3〜2.0トンの炭素隔離が可能であり、土壌健康や収量向上にも寄与する。大規模な普及には政策的支援と経済的インセンティブが必要とされる。

English

This review comprehensively evaluates the role of soil organic carbon (SOC) sequestration in mitigating climate change and enhancing agricultural sustainability. Management practices like conservation agriculture, agroforestry, cover cropping, and biochar can sequester 0.3-2.0 t C/ha/year, improving soil health and yields. Large-scale adoption requires supportive policies and economic incentives.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本では、農地土壌への炭素貯留は「みどりの食料システム戦略」やカーボン・クレジット制度（J-クレジット）と関連し、農業分野の脱炭素化と持続可能な農業経営の両立に寄与する。本レビューは、国内の農地管理や政策立案に科学的根拠を提供する。

In the global GX context

Globally, SOC sequestration is recognized as a nature-based climate solution, relevant to frameworks like the Paris Agreement and corporate Scope 3 emissions from agriculture. This review provides evidence for policymakers and practitioners on effective land management practices, supporting climate mitigation and sustainable agriculture goals.

👥 読者別の含意

🔬研究者:Provides a comprehensive synthesis of SOC sequestration mechanisms and management impacts, useful for further research.

🏢実務担当者:Offers practical guidance on SOC-enhancing practices for agricultural sustainability and potential carbon credits.

🏛政策担当者:Highlights the need for supportive policies and incentives to scale up SOC sequestration for climate goals.

📄 Abstract（原文）

A significant method for reducing greenhouse gas emissions while enhancing the environmental quality and profitability of agricultural systems is through the process of soil organic carbon (SOC) sequestration. This review assesses the effects of SOC on climate mitigation, the sustainability of food production and the enhancement of soil health. Globally soils are estimated to store about 1500 to 2400 Gigatons of carbon which represents three times more carbon than exists in the atmosphere or all plant biomass; therefore, the maintenance of SOC is an important mechanism for controlling the climate. This review integrates what is currently known about the mechanisms of SOC, the influence of various factors on SOC, the management practices which can increase SOC, and the quantitative reduction of greenhouse gas emissions possible from SOC sequestration in a variety of agroecosystems. Results show that conservation agriculture, agroforestry, cover cropping and biochar additions can result in the sequestration of 0.3 to 2.0 metric tons of C/ha/year, although large variability exists among soils and climates based upon management practices. In addition to the reduction of greenhouse gases, SOC-enhancing management practices have many additional benefits including improved water retention, improved nutrient cycling, improved biodiversity, and improved crop yields. However, to achieve global greenhouse gas emission reductions will require the adoption of these practices over billions of ha of land and will need to be implemented within a supportive regulatory framework, economic incentive program, and innovative technology. This review presents a complete assessment of the literature for those who would like to develop policies, practice and research related to SOC sequestration for reducing greenhouse gas emissions and improving the sustainability of agricultural systems.
