Interactions entre systèmes fourragers et systèmes de grandes cultures à l'échelle d'un territoire. Intérêts pour l'environnement
In certain regions where mixed farming prevails, the specialization of the farms (with the progressive disappearance of livestock) has brought about uniform methods of land occupation which run counter the environmental functions of farming. For that matter, grasslands and perennial covers have beneficial effects, but their insertion or their maintenance have to be thought out at the territorial scale.
