The dehesa system is the most characteristic type of extensive farms in the Iberian Peninsula. Dehesa farms have been traditionally the sustenance of the extensive ovine and porcine livestock production, though in the last decades, bovine and hunting cattle raising have taken special importance too.
Nowadays, the public intervention caused by the reform of the CAP and the new agri‑environmental measures has been important effects on the regulation and reorganization of livestock productions. Nevertheless, there is a lack of information about the structure of dehesa systems. This paper deals with an analytical case study of dehesa systems of Badajoz province, with a summary of the main technical indicators of cattle structure and yields, use of land and degree of use of energetic resources by livestock. This is an improvement of the internal knowledge of dehesa systems that allows their typification, the study of their external dependence and the degree of use of the natural environmental resources.
