Abstract

Within the framework of a general reflection on technical change, this paper is aimed at opposing an approach that assigns a primary role to the progress of biological knowledge in the evolution of the agro-food system. Instead, the importance of the complex and heterogeneous nature of the transformation under way is highlighted. Biotechnological research risks falling into a reductionist rut when it ignores the structural and organizational changes in the agro-food industry and the contribution of other technical innovations, especially in the field of computers and in product innovation. If one really wants to speak of a biotechnology revolution, one must specify that it is essentially a scientific revolution: at the production level the contribution of the biotechnologies is still potential, while the agro-food sector is going through a period of profound change
