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