ブラジル・パラナ州西部の家族農業従事者85戸を調査し、気候変動の認識と適応戦略を分析。主成分分析とクラスター分析により、農家を3グループに分類し、多様な脆弱性と適応能力を明らかにした。構造的制約や資金・技術支援の不足が共通課題であり、気候レジリエンス強化のための政策的支援の必要性を示す。
English
This study surveyed 85 family farms in western Paraná, Brazil, to analyze climate change perceptions and adaptation strategies. Using PCA and cluster analysis, farmers were grouped into three distinct clusters reflecting varying vulnerabilities and adaptive capacities. Common challenges included structural limitations, restricted financial access, and limited technical assistance, highlighting the need for targeted public policies to strengthen climate resilience in family farming.

📄 Abstract（原文）
Climate change impacts the ability of food systems to provide adequate nutrition to a growing population. Understanding family farmers’ perceptions of climate change is crucial for implementing mitigation and resilience strategies. This research analyzed how family farmers in the western region of Paraná, Brazil, perceived the effects of climate change on their productive activities and how they responded and adapted. During visits to 85 rural properties, a structured questionnaire using a five-point Likert scale was administered to assess climate change impacts, response limitations, and mitigation strategies. Results were analyzed using Principal Component Analysis (PCA) and HCA. Farmers strongly perceived increased temperatures and reduced rainfall, which were associated with a higher incidence of agricultural pests and diseases, water scarcity, and increased production costs. The main adaptation strategies adopted included the use of organic matter for soil cover, irrigation, crop diversification, and organic fertilizers. Farmers were grouped into three clusters based on hierarchical cluster analysis using PCA indices, sociodemographic variables, and productive activities: (i) Diversification and Structural Limitations; (ii) Experience and Concerns about Productivity; and (iii) Sustainable Practices and Vulnerability to Resources. These groups presented distinct socioeconomic and productive characteristics, reflecting differences in vulnerability and adaptive capacity. Structural limitations, restricted access to financial resources, and limited technical assistance were common challenges among the groups. The findings reinforce the need for targeted public policies and technical support strategies to strengthen climate resilience in family farming systems.
