The objective of this study was to analyze the impact of climate change on food security in peasant communities of the upper Santa River basin, Peru. The research followed a quantitative approach with a non-experimental, descriptive, and cross-sectional design. The population consisted of 680 household heads from Cátac and Huamarín, from which a non-probabilistic sample of 102 participants directly involved in agricultural and livestock activities was selected. A structured questionnaire was applied, validated by expert judgment and showing adequate reliability (Cronbach’s alpha = 0.87). Data were processed using frequencies and percentages. The results showed that 75.5% of participants perceived significant changes in temperature and climate patterns, mainly atypical frosts, thermal variability, and an increase in pests. Likewise, 86.3% reported some level of decline in food availability, while 69.6% expressed limitations or uncertainty regarding their economic capacity to purchase food. In addition, 58.8% indicated that they had not implemented adaptation measures. It is concluded that climate variability intensifies the socio-food vulnerability of the communities studied by affecting agricultural and livestock production, economic access to food, and local capacities for territorial resilience.
