Genetic erosion and in situ conservation are two strategies for resilience in food security. The main objective of this study was to know the interactions between these two concepts into the farmlands facing climate change threats. A survey of 224 peanut’s farmers of 75 localities was represented by two groups; North region (zone 1) with 111 farmers and South region (zone 2) with 113 farmers. 23 variables (questions), were divided in two categories; variables of protection (8 questions) and variables of production (15 questions). Factorial analysis of components (FAC) was used to construct in situ conservation models for the North and South system of production. The Cramer test, were used to link genetic erosion and in situ conservation. FAC shows that, models of in situ conservation are very specific inside each zone.
