In order to approach farmers’ adoption behavior of innovative cropping systems (ICS) on a sample of specialized cereal French farmers, a methodological protocol combining stated preferences and perceptions is designed. An original choice modelling protocol allows analyzing farmers’ preferences facing an adoption decision (dichotomous choice) but also the level of adoption (number of hectare adopted). By gathering the data on farmers’ preferences, perceptions and characteristics, this experiment allows revealing the determinants of the adoption of ICS.
