La complexité des parcellaires : une contrainte ou un atout pour réduire les achats de concentrés en systèmes laitiers de montagne ?

Abstract : In mountain areas, breeders are heavily constrained by their field pattern. However, some studies suggest that the diversity of grasslands can be good for the economy of food inputs. This paper aims to identify how, and in what situations, the characteristics of the field pattern in grassland farms can increase autonomy for livestock’s food system. We characterize the field patterns of 25 dairy farms in a French mountain region. We thus investigate the link between the characteristics of field patterns and levels of food purchases. Two main ways of increasing autonomy are identified: Producers deal with their field pattern (i) adjusting their farm management (choice in crops allocation, infrastructure, genetics, production targets etc.) and / or (ii) acting upon their field pattern to suit their needs (eg by seeking diversity in plots’ altitude to reduce climate risks). This confirms that the complexity of the field patterns can be mobilized or not by breeders as an asset. We also show that economies of inputs and the shape of field patterns are independent of farm sizing, even if the stocking rate remains a key element.
