本レビューは、ゴム・ココナッツ・ビンロウなどの高木作物と、香辛料・飲料・薬用植物などの高価値下層作物を組み合わせた多層アグロフォレストリーの利点を総合的に分析。単作と比較して炭素貯留量が20～50%増加し、地温を3～5℃低下させるなど、気候変動適応と緩和に寄与する。土地等価比（LER）は1.2～1.8と高く、生産性と収入多様化を両立するが、種間競争や病害リスクへの注意が必要。
English
This review synthesizes evidence on multi-strata agroforestry combining rubber, coconut, and areca overstory with high-value understory crops. Compared to monocultures, these systems increase carbon storage by 20-50%, reduce midday temperatures by 3-5°C, and achieve land equivalent ratios of 1.2-1.8, enhancing productivity and income diversification. However, outcomes depend on species complementarity and management, with gaps in long-term productivity and socioeconomic barriers.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本国内では直接的なGX政策との関連は薄いが、熱帯地域での気候変動適応・緩和策として、日本企業の海外農業投資やサプライチェーンにおける持続可能性評価に示唆を与える。特に、パーム油や天然ゴムなどの調達先での環境・社会配慮が求められる中で、アグロフォレストリーの導入は生物多様性と炭素貯留の両面で貢献しうる。
In the global GX context
This paper contributes to global GX scholarship by providing empirical evidence on nature-based solutions that integrate climate mitigation (carbon sequestration) with adaptation (temperature regulation) in tropical agriculture. It supports international frameworks like the EU Deforestation Regulation and ISSB's biodiversity-related disclosures by quantifying co-benefits of agroforestry systems.

📄 Abstract（原文）
CONTEXT Tropical agriculture faces increasing challenges in sustaining production and rural livelihoods while addressing climate change, biodiversity loss, soil degradation, and resource limitations. Multi-strata agroforestry systems integrating perennial overstory crops with high-value understory species offer a promising pathway for climate-smart intensification and sustainable tropical agriculture. OBJECTIVE This review synthesizes evidence from multi-strata agroforestry systems combining major overstory crops, including Hevea brasiliensis , Cocos nucifera , and Areca catechu , with high-value understory crops such as spices, beverage, and medicinal plants. We develop a trait-based framework linking overstory characteristics, ecological interactions, management strategies, and ecosystem multifunctionality. METHODS A comprehensive literature synthesis was conducted using Web of Science Core Collection, Scopus, and Google Scholar, focusing on productivity, ecosystem services, resource-use efficiency, management practices, and socioeconomic outcomes. The evidence was organized around overstory–understory interactions, climate resilience, ecosystem services, productivity, and adoption challenges. RESULTS AND CONCLUSIONS Multi-strata agroforestry systems enhance carbon (C) storage, biodiversity, soil functions, and land-use efficiency compared with monocultures, with land equivalent ratios (LER) frequently exceeding 1.0. Reported evidence indicates that agroforestry systems can increase C storage by 20–50%, improve soil organic carbon (SOC) stocks by 10–20% compared with monocultures, and reduce midday air and soil temperatures by approximately 3–5 °C and 2–4 °C, respectively. High-value understory crops further enhance productivity and income diversification, with LER values commonly ranging from 1.2 to 1.8 and exceeding 2.0 in some shade-adapted crops. However, outcomes remain context-dependent due to competition for light, water, and nutrients, as well as potential pest and disease risks. Optimized performance depends on complementary species selection, canopy regulation, and adaptive soil fertility management. Key knowledge gaps remain in long-term productivity, C sequestration dynamics, resource competition thresholds, and socioeconomic barriers. SIGNIFICANCE Diversified overstory–understory agroforestry systems represent a nature-based solution for developing resilient tropical landscapes by integrating agricultural productivity, biodiversity conservation, ecosystem services, and climate change mitigation.
