ガーナ農村部の食用作物農家535世帯を対象に、洪水・干ばつ・気温上昇・降雨不順といった気候リスクが農林複合システム導入意欲に与える影響を、防護動機理論とイノベーション普及理論に基づきロジスティック回帰で分析した。洪水経験が最も強い規定要因であり、気候情報サービスへのアクセスも導入意思決定を有意に左右する。農林複合は脆弱な小規模農家の適応・緩和策として有望だが、気候情報へのアクセス改善と政策支援が不可欠と結論づける。
English
Surveying 535 smallholder food-crop farmers in rural Ghana, this study uses protection motivation and innovation diffusion theory with logistic regression to assess how floods, droughts, rising temperatures and erratic rainfall shape agroforestry adoption willingness. Flood occurrence is the strongest driver, and access to climate information services significantly influences adoption decisions. The authors argue agroforestry can be a transformative adaptation strategy for vulnerable farmers if climate information access is improved, recommending targeted policies.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX文脈とは直接の接点は薄いが、気候適応策・農業分野の適応ファイナンスやサプライチェーン（カカオ等輸入農産物）の気候リスク評価に関心を持つ日本企業・投資家にとって参考となる。
In the global GX context
This adds Global South empirical evidence on climate adaptation in agriculture, relevant to global discussions on adaptation finance, supply-chain climate risk, and nature-based solutions under frameworks like TCFD/ISSB which increasingly touch agricultural value chains. It complements disclosure scholarship by showing how climate risk perception drives on-farm innovation adoption.

📄 Abstract（原文）
Agroforestry is increasingly promoted as an important climate adaptation and mitigation strategy, yet its adoption can be hampered or facilitated by farmers’ climate change experiences and perceived risks, as climate risks are associated with smallholder farmers’ agricultural innovation adoption decisions. In Ghana, agroforestry is promoted largely in cocoa and cashew-based farming systems, with limited knowledge of its adoption in food crop farming systems, where land degradation and farm expansion are high. Grounded in the protection motivation theory and the innovation diffusion theory, this study assesses the influence of floods, droughts, rising temperature and erratic rainfall on smallholder farmers’ willingness to adopt agroforestry in food crop farming systems in rural Ghana. Relying on a survey data from 535 smallholder farmers in four farming communities, we analyzed data using basic descriptive and logistic regression analyses. Results show that flood occurrence is the most crucial climate risk that influences farmers’ agroforestry adoption decision. Similarly, having access to climate information services significantly shapes agroforestry adoption decision. Considering that floods are recurrent with associated impacts on crop production, agroforestry can serve as a transformative and resilient-building agricultural innovation for vulnerable smallholder farmers, if farmers have improved access to climate information services. Targeted policies and interventions that enhance farmers’ knowledge of agroforestry and strengthen adaptive capacities through climate information services are highly recommended to guide informed adoption decisions in smallholder food crop farming systems.
