Adoption d’innovations par les agriculteurs : rôle des perceptions et des préférences

One way to reconcile the issues of productivity and environmental protection for field crops farmers is the implementation of systemic agroecological innovations. These innovations are complex combining traditional agricultural tools, such as the lengthening of rotations, with innovative production techniques such as precision agriculture. The adoption of these innovations creates additional uncertainty for farmers. Several studies have shown that risk aversion is a major break in the adoption of agricultural innovations. But others individual agronomic, economic and psychosocial determinants also affect the adoption decision process. However, among the determinants identified in the literature, few seem common and generalized to all production context. Other determinants, not directly observable, influence the adoption decision. This article presents a literature review to identify the role of observable and unobservable determinants, such as perceptions and preferences, in the adoption process of agroecological innovations.
