本レビューは、再生農業の7つの実践（不耕起、被覆作物、輪作、アグロフォレストリー、堆肥、バイオ炭、放牧）が土壌有機炭素や微生物多様性に及ぼす影響を272文献から統合。特に熱帯・途上国での導入経路に焦点を当て、政策支援や農家主体の普及の重要性を指摘。効果のばらつきや炭素隔離の永続性に関する慎重な解釈を促す。
English
This systematic review synthesizes evidence from 272 sources on seven regenerative agriculture practices (e.g., no-till, cover crops, agroforestry) and their effects on soil organic carbon, aggregate stability, and microbial diversity. Focusing on tropical and developing-country contexts, it highlights adoption barriers such as policy misalignment and weak land tenure, and calls for supportive frameworks and farmer-centered dissemination. The review cautions against overstating carbon sequestration permanence and generalizability.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では土壌炭素貯留が農林水産省の「みどりの食料システム戦略」で注目されるが、本論文の知見は熱帯・途上国向けであり、日本の温帯・稲作主体の農業への直接適用には注意が必要。ただし、標準化された土壌健康指標や長期モニタリングの重要性は日本にも示唆を与える。
In the global GX context
This paper provides a comprehensive global synthesis of regenerative agriculture's potential for climate mitigation, relevant to IPCC assessments and carbon offset methodologies. It informs the ongoing debate on soil carbon sequestration permanence and the need for standardized metrics, which is critical for global carbon accounting frameworks like the GHG Protocol. The focus on developing-country contexts addresses a gap in the literature.
👥 読者別の含意
🔬研究者:研究者は、再生農業の土壌炭素効果に関する既存証拠の統合と、今後の研究課題（長期クロスサイト試験、標準化指標）を把握できる。
🏢実務担当者:農業関係者は、各実践の効果のばらつきや移行期の収量トレードオフを理解し、導入判断の参考にできる。
🏛政策担当者:政策立案者は、再生農業推進には土地所有権や信用アクセスなどの制度的支援が必要であることを認識すべき。
📄 Abstract（原文）
Soil degradation, intensified by conventional cropping practices and a changing climate, undermines global food systems and ecosystem function. This systematic review synthesises peer-reviewed and institutional evidence published between 2000 and 2025 on the role of regenerative agriculture in restoring soil function and contributing to climate-change mitigation, with an emphasis on adoption pathways in tropical and developing-country contexts. Using PRISMA 2020 procedures, three reviewers screened 10,211 records identified in Scopus, Web of Science, and Google Scholar between 25 August and 25 October 2025 and retained 272 sources after full-text eligibility assessment. The synthesis spans seven core practices, namely minimal tillage, cover cropping, crop rotation with legumes, agroforestry, compost application, biochar amendment, and holistic planned grazing, and evaluates their effects on soil organic carbon, aggregate stability, water retention, cation exchange capacity, pH regulation, and microbial diversity. The reviewed evidence indicates that regenerative practices, when adapted to local agroecological conditions, are associated with measurable improvements in soil function and with concurrent benefits for climate adaptation and mitigation. Effect sizes vary substantially across climate, soil type, baseline degradation status, and implementation intensity, and the literature counsels caution about over-stating carbon-sequestration permanence, transition-period yield trade-offs, and the generalisability of pilot-scale evidence. Adoption barriers include policy misalignment, weak land tenure, limited credit access, and insufficient extension support, particularly for smallholder producers. The synthesis indicates that the contribution of regenerative agriculture to sustainable food systems is conditional on supportive policy frameworks, long-term cross-site research, standardised soil-health metrics, and farmer-centred dissemination mechanisms.
