L'analyse des trajectoires des exploitations agricoles. Une méthode pour actualiser les modèles typologiques et étudier l'évolution de l'agriculture locale

To be useful for extension services (farmers advising and agricultural policies orientation), farm typology must be updated regularly. Nevertheless, typology updating can't be reduced to build ex nihilo a new typology. First, the previous typology provides essential references to analyse farm trajectories and to caracterize local agricultural changes. Then, the elaboration of the new typology is mainly based on the results of this first analysis.
