間作は、同一土地で複数作物を同時栽培し、生物多様性、栄養循環、生態系サービスを向上させる持続可能な農業戦略である。特にマメ科と穀物の組み合わせで窒素肥料を最大60%削減し、温室効果ガス排出を低減。アジア、アフリカ、欧州での事例研究が、生産性向上と土壌健全性改善を示すが、大規模普及には技術的・政策的課題が残る。
English
Intercropping, the simultaneous cultivation of multiple crops on the same land, enhances biodiversity, nutrient cycling, and ecosystem services for sustainable agriculture. Integrating legumes with cereals can reduce synthetic nitrogen fertilizer by up to 60%, lowering greenhouse gas emissions. Case studies across Asia, Africa, and Europe demonstrate productivity gains and improved soil health, but large-scale adoption faces challenges in mechanization and policy support.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
本論文はインドの研究だが、日本の農業にも間作の導入が温室効果ガス削減や土壌炭素貯留に貢献する可能性を示唆する。ただし、GX（グリーントランスフォーメーション）の文脈では、SSBJ開示やカーボン会計への直接的な関連性は薄い。
In the global GX context
This review highlights intercropping as a nature-based solution for climate change mitigation through reduced fertilizer use and enhanced carbon sequestration. It contributes to global GX goals by providing evidence for sustainable intensification, relevant to ISSB's agriculture sector guidance and TCFD's climate risk mitigation strategies.

📄 Abstract（原文）
Intercropping, the simultaneous cultivation of two or more crops on the same land, is a vital strategy for achieving sustainable, resilient and resource-efficient agriculture. By exploiting spatial and temporal complementarities, intercropping enhances biodiversity, nutrient cycling and ecosystem services while minimising environmental impacts. The practice significantly improves land productivity, often reflected by land equivalent ratios (LER) greater than 1.2, indicating superior yield per unit area compared to monocultures frequently reported. Integrating legumes with cereals reduces synthetic nitrogen fertiliser requirements by up to 60 %, thereby lowering greenhouse gas emissions and enhancing soil fertility. Ecologically, intercropping fosters beneficial microbial communities, enhances arbuscular mycorrhizal activity and improves soil organic carbon and nutrient-use efficiency. Agronomically, it suppresses weeds, pests and diseases through diversified canopy structure and allelopathic interactions, while enhancing water-use efficiency and drought resilience in some crop combinations. Socioeconomically, intercropping diversifies farm income, mitigates risks and strengthens smallholder livelihoods. Case studies across Asia, Africa and Europe demonstrate substantial productivity gains, improved soil health and higher carbon sequestration in cereal-legume and agroforestry-based systems. Despite these benefits, challenges such as management complexity, limited mechanisation compatibility and inadequate policy support constrain large-scale adoption. Future directions emphasise breeding for intercropping-suitable cultivars, integrating precision agriculture and digital tools and implementing supportive policy frameworks. As a nature-based solution, intercropping represents a key component cornerstone for sustainable intensification, contributing to climate change mitigation, food security and ecological resilience.
