This pedagogic experiment is carried out with students of the Ecole Nationale Supérieure d'Agronomie et des Industies Alimentaires of Nancy (France)in the last year of their formation ("ingénieur agronome"). Since five years, this pedagogic module is organized to teach them to confront with local stakeholders about rural and agricultural development. This module is divided in tow formation sessions: a first session to learn methodological tools and technical data (roughly one week long) and a second session (one week) taking place away from the class-room in a rural area. Since five years, the originality of the chosen areas is that it presents new agricultural models that they did not approach before. They build a presentation which summarizes their local's interviews and diagnostic of the site using landscape agronomy methods. The aim is to train students to a collaborative approach through a multidisciplinary work applied on a same region with a single stakeholders question.
