Characterizing the practices of a cropping system with respect to sustainability

Abstract

In order to analyse the performances of four crops systems, a procedure combining environmental, technical and economical criteria was set up. The analysed crops systems relate to four actual farms in the Midi-Pyrenees area. Their production targets are very different and linked to specific assets and restraints, which have been identified. After detailing the cropping practices implemeted, the indicators chosen to evaluate theses practices and the results obtained are described and discussed. This analysis shows that no crops system is in every respect superior to the others, but that it is possible to characterize the performance of each in its own context. Firstly this analysis enables farmers to situate themselves in relation to the sustainability of their farm, secondly to imagine ways to improve their practices, and thirdly to put forward their practices with regard to regulations or possible certifications.
