Polyculture-élevage ou hyper-spécialisation territoriale ? Deux scénarios prospectifs du système agro-alimentaire français

Abstract : Current French agro-food system is characterized by a high level of territorial specialization, either towards stockless crop farming, or towards specialized animal farming highly dependent on feed imports. The resulting opening of nutrient cycles causes severe environmental concern. Here we present a radical scenario aiming at increasing territorial protein autonomy and reconnecting agricultural production to food consumption with a lower animal protein content. This scenario is compared to another one pursuing the opening and specialization trends observed since the last decades. Results show that the reconnected scenario makes it possible to meet the futur national food demand while still exporting significant amounts of cereals to the international market with much better environmental performances.
