Categorization of grazing systems to aid the development of land use policy in Aragon, Spain

Abstract

Abstract Ruminant livestock depends primarily on forage and grazing resources from both natural pastures and from cultivated land. Low‐input large‐scale grazing systems constitute a substantial part of what is termed High Nature Value farmland in Europe. Developing a typology of categories of livestock systems within a region is an important step in understanding land uses that involve ruminant livestock systems and their use of feed resources, and in appraising policy options. This study developed a typology based on the municipalities of the region of Aragon in the north‐east of Spain on the basis of the feed resources for ruminant livestock. A clustering analysis was applied to the following three types of criteria: (i) crop types; (ii) vegetation types of uncultivated land and (iii) stocking rate of dairy cattle, beef cattle, sheep and goats. A total of thirty‐nine variables were used. The cluster methodology allowed relatively homogeneous groups of municipalities, termed territories, with differentiating characteristics to be obtained. A Geographic Information System was applied to locate spatially the territories. From the twelve territories identified, it was concluded that there was a low use of natural pastures and high use of resources of cultivated origin in livestock systems in Aragon.
