本レビューはインドの土壌炭素研究の現状を整理し、土壌有機炭素・粒状有機炭素・鉱物結合炭素などの動態と、保全農業・有機物施用・アグロフォレストリー等の管理効果を評価する。分光法・リモートセンシング・機械学習・MRVの進展を概観し、長期データ不足や深層土壌炭素の不確実性を課題として指摘。長期実験とデジタル土壌炭素マッピングを統合する「Soil Carbon Futures in India」ロードマップを提案する。
English
This review synthesizes India's soil carbon research, covering organic, particulate, mineral-associated and microbial carbon pools and their responses to conservation agriculture, residue retention, biochar and agroforestry. It surveys advances in spectroscopy, remote sensing, GIS, machine learning and MRV systems, while flagging gaps in long-term datasets, deep-soil carbon and smallholder-specific evidence. A research roadmap, 'Soil Carbon Futures in India,' is proposed to link long-term experiments, digital soil-carbon mapping and farmer-centred policy.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では農地土壌炭素貯留事業やJ-クレジットの農地管理方法論が拡大しており、MRVやデジタル土壌マッピングの議論は国内制度設計に示唆を与える。インドの小規模農家向け枠組みは、アジア域での土壌炭素クレジット連携を考える上で参考になる。
In the global GX context
Globally, soil carbon is central to the 4 per 1000 initiative, voluntary carbon markets and the emerging agricultural MRV standards under Article 6 and CSRD-linked supply-chain reporting. This review adds a Global South, smallholder-focused perspective that is underrepresented in TCFD/ISSB-aligned disclosure scholarship, and highlights MRV uncertainty as a barrier to credible soil-carbon credits.

📄 Abstract（原文）
Soil carbon is a critical component of agricultural soil health, ecosystem functioning, climate regulation, and the long-term resilience of food production systems. In India, increasing climate variability, rising temperatures, droughts, floods, soil degradation, and declining soil organic matter pose significant challenges to sustainable agricultural production. This review examines the current status of soil carbon research in India and evaluates its potential contribution to climate-resilient agriculture. The review synthesizes evidence on major soil carbon pools, including soil organic carbon, particulate organic carbon, mineral-associated organic carbon, dissolved organic carbon, microbial biomass carbon, and aggregate-associated carbon, with emphasis on their formation, stabilization, persistence, and sensitivity to environmental and management factors. The distribution and dynamics of soil carbon across major Indian agro-ecological regions and soil types are discussed, along with the effects of conservation agriculture, crop diversification, residue retention, cover cropping, organic amendments, biochar, agroforestry, integrated nutrient management, and improved water management. Particular attention is given to the interactions among soil carbon, soil health, crop productivity, greenhouse-gas emissions, and resilience to drought, heat, and excess rainfall. Recent advances in soil-carbon measurement, spectroscopy, remote sensing, geographic information systems, machine learning, process-based modelling, and measurement, reporting and verification (MRV) systems are also reviewed. The analysis highlights major research gaps, including limited long-term field datasets, inadequate representation of deep-soil carbon, uncertainty in carbon permanence, insufficient integration of CO2, CH4 and NO2 emissions, and limited region-specific evidence for smallholder farming systems. Finally, a research roadmap, termed “Soil Carbon Futures in India,” is proposed to integrate long-term experimentation, digital soil-carbon mapping, robust MRV frameworks, farmer-centred management, and supportive policy mechanisms. Strengthening soil-carbon research and its translation into region-specific management strategies can provide an important pathway for improving soil health, sustaining agricultural productivity, mitigating greenhouse-gas emissions, and enhancing the climate resilience of Indian agriculture.
