Evaluation environnementale d’un système bovin viande et cultures en Agriculture biologique : cas de la ferme expérimentale de Thorigné d'Anjou

Abstract : In view of world population increase, the issue is to succeed to feed the planet while knowing that the resources become scarce. Farming is in narrow link with the environment. LCA environmental assessment allows calculating the potential impacts of agricultural practices on the environment. In France, the will to turn to a sustainable farming is taking shape. Through the study of organic beef system of the experimental farm of Thorigné d’Anjou, it is demonstrated that this system can be efficient for both production and environment. These good results are linked to the diverse innovative practices introduced such as multi-species grasslands, the production of cereallegume mixtures, or even horse bean. The system has thus come up with a good balance between productivity and environment. In other systems, either organic or conventional, it is also possible to reduce the environmental impacts, by optimizing their management, while remaining coherent with the implemented practices. The introduction of legumes in crop rotations to reduce the nitrogen inputs, or even the implementation of plant cover to limit the losses towards water, are excellent examples, set up in the farm of Thorigné d’Anjou.
