Crop–livestock integration beyond the farm level: a review

Paradoxically, the number of crop–livestock farms is declining across Europe, despite the fact that crop-livestock farms are optimal to the sustainability of agriculture. To solve this issue, crop–livestock integration may be organized beyond the farm level. For instance, local groups of farmers can negotiate land-use allocation patterns and exchange materials such as manure, grain, and straw. Development of such a collective agricultural system raises questions about how to integrate crops and livestock among farms, and the consequences, impacts, and conditions of integrating them. This article reviews the different forms of crop–livestock integration beyond the farm level, their potential benefits, and the features of decision support systems (DSS) needed for the integration process.
