Résumé
In the framework of the Bretagne and Pays de la Loire, an agroclimatic zoning of these two regions was produced. The objective was to identifyterritories with homogeneous climatic risks. These risks were defined by twelve climatic variables associated toagricultural issues that were identified and selected by the respective Regional Chambers of Agriculture. Thesevariables were spatialized by multiple regression between climate data and geographic variables. The typology resultedfrom a k-means clustering of a principal component analysis of spatialized climatic variables. The statistical resultprovides a map of the two regions divided into twelve agroclimatic sectors.
