France lost a quarter of its farmers between 2000 and 2016, which testifies to far-reaching changes in its agricultural sector. Over and above this quantitative trend, the sector is constantly reinventing itself through the efforts of the women and men who contribute to it, and whose careers and skills are being transformed. Aiming at a better understanding of these profound changes, the Centre for Studies and Strategic Foresight (CEP) gathered a working group of around thirty experts, most of them researchers, who combined their economic, sociological and statistical analyses. The Actif'Agri study describes the resulting overview in detail in the course of a dozen chapters. The present note sets out its main lessons.
