Agricultural insurance is a method of combating agricultural risks. Today, only 7% of Tunisian farmers take out insurance; this is due to both socio-economic and structural reasons linked to the adaptation of insurance products to the latent needs of farmers. The aim of this study is therefore to identify the factors that motivate cereal growers in the Medjez El Bab region to take out hail insurance. From a methodological point of view, the Logit model enabled us to highlight the significant variables that influence the farmer's choice of whether or not to be insured. The results show that credit, farm size, age, yield per hectare and weight of cereals positively affect the farmer's decision.
