南部アフリカの小規模農家を対象に、気候変動が食料安全保障を脅かす経路と適応策を質的にレビューした研究。昇温・降雨変動・干ばつ・洪水が作期短縮や収量低下を招く一方、作物多様化や耐乾性品種、保全農業、アグロフォレストリー等の適応が行われている。資金・灌漑・普及・土地権限・市場・気候情報の不足から導入は不均一で、農家を均質視せず制度・インフラ・社会保護を組み合わせた統合的適応が必要と論じる。
English
A qualitative review of how climate change undermines food security in Southern Africa and which adaptation pathways suit smallholder farmers. Warming, erratic rainfall, droughts and floods shorten growing seasons and cut yields, while farmers adopt crop diversification, drought-tolerant varieties, conservation agriculture, agroforestry and climate services. Adoption stays uneven due to gaps in finance, irrigation, extension, tenure, infrastructure and markets; the paper argues for coordinated packages linking farm practices with inclusive institutions and social protection.

In the global GX context
Sits outside core disclosure frameworks (TCFD/ISSB/CSRD) but speaks to the adaptation and physical-risk side of climate scholarship, relevant to supply-chain and food-security risk analysis in global GX debates.

📄 Abstract（原文）
Climate change threatens food security in Southern Africa by disrupting rainfed production, rural incomes, dietary quality, and the stability of food supplies. This qualitative review examines these linkages and identifies adaptation pathways relevant to smallholder farmers. Database and repository searches initially identified 45 records; after screening titles, abstracts, and full texts, 20 core sources were retained for thematic analysis, while supplementary sources were used for conceptual and methodological context. The synthesis shows that rising temperatures, erratic rainfall, droughts, and floods shorten growing seasons, reduce soil moisture, damage crops and livestock, and intensify seasonal food insecurity. Farmers respond through crop diversification, drought-tolerant crops, conservation agriculture, agroforestry, water harvesting, livelihood diversification, and climate-information services. However, adoption remains uneven because finance, irrigation, extension, secure land tenure, infrastructure, markets, and usable forecasts are limited. The paper argues that no single intervention is sufficient. Effective adaptation requires coordinated packages that connect farm-level practices with inclusive institutions, climate services, rural infrastructure, and social protection. Such integration can strengthen food availability, access, utilisation, and stability without treating smallholders as a homogeneous group.
