保全農業（CA）は、土壌撹乱の最小化、有機被覆、種の多様化の3原則に基づき、土壌健全性を改善し、炭素隔離（0.1～0.93 Mg/ha/年）、栄養循環向上、生物多様性増進などの効果をもたらす。また、干ばつや高温に対する耐性を高め、長期的には収量増加（最大9.3%）を示す。一方、短期的な収量低下や除草剤抵抗性などの課題も存在する。適切に実施すれば、気候変動緩和と持続可能な農業に有効。
English
Conservation Agriculture (CA) improves soil health through minimum disturbance, organic cover, and diversification, enhancing carbon sequestration (0.1–0.93 Mg/ha/yr), nutrient cycling, and biodiversity. It increases resilience to drought and heat, with long-term yield gains up to 9.3%. However, short-term yield penalties, herbicide resistance, and high costs are barriers. Properly adapted, CA supports climate mitigation and sustainable intensification.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の農業では、耕地の約6割が水田であり、畑作での不耕起栽培は限定的だが、気候変動適応や土壌炭素貯留の観点から、本論文の知見は日本農業のGXにも示唆を与える。特に、地域適応型の保全農業技術の導入は、有機農業やスマート農業との連携が期待される。
In the global GX context
This paper provides global evidence on Conservation Agriculture's role in climate mitigation and adaptation through soil carbon sequestration. For international GX contexts, it highlights nature-based solutions that can be integrated into corporate sustainability strategies, particularly for agricultural supply chains addressing Scope 3 emissions.
👥 読者別の含意
🔬研究者:Useful for agricultural and climate scientists examining sustainable intensification and soil carbon dynamics.
🏢実務担当者:Farmers and agribusiness can use CA principles to improve soil health and resilience, though short-term trade-offs require careful management.
🏛政策担当者:Offers evidence for designing agricultural policies that incentivize carbon sequestration and climate adaptation in farming systems.
📄 Abstract（原文）
Conservation Agriculture (CA) is a sustainable farming system built on three core principles minimum soil disturbance, permanent organic soil cover, and species diversification that aims to reverse soil degradation, enhance ecosystem services, and ensure long-term crop productivity. This review synthesizes evidence demonstrating that CA significantly improves soil physical, chemical, and biological health compared to conventional tillage systems. Key benefits include enhanced aggregate stability and water infiltration rates, increased soil organic carbon (SOC) sequestration (0.1–0.93 Mg/ha/year depending on environment), improved nutrient cycling (notably higher available P and K), elevated microbial biomass and fungal diversity, and substantial increases in earthworm populations that contribute to nitrogen mineralization and yield gains. These changes translate into greater resilience against abiotic stresses such as drought and heat waves, with long-term trials showing yield increases of up to 9.3% under warming conditions and superior water-use efficiency in rainfed environments. However, short-term yield penalties, herbicide resistance risks, residue competition in mixed crop-livestock systems, high mechanization costs, and challenges in managing soil acidity in no-till systems remain important barriers, particularly for smallholder farmers in developing regions. Integrated weed management, precision technologies, adaptive liming strategies, and service-provision models for machinery are identified as critical pathways to overcome these constraints. Overall, when correctly implemented and locally adapted, CA offers a proven strategy for restoring soil health, stabilizing yields, mitigating climate change impacts, and advancing sustainable intensification of global agriculture.
