Abstract

This chapter proposes to estimate the technical efficiency in agricultural grazing systems (dairy, beef and mixed) in Azores, in the year 2002. This research used 184 agricultural farms of FADN – Farm Accountancy Data Network. DEA, a non-parametric methodology, was used to estimate efficiency by means of DEAP software.

The results have shown that the average technical efficiency in the dairy grazing system was 63.2% (CRS) and was higher (71.4%) in VRS, and the scale efficiency was about 89.2%. In beef grazing system, the average technical efficiency (CRS) was 69.4%; VRS and the scale efficiency were 82.9 and 84.2%, respectively. In the mixed grazing system, the average technical efficiency (CRS) was 89%, the VRS was higher (99.24%) and the scale efficiency was 89.8%. The mixed system is the most efficient, and about half (46.7%) of the farms were efficient. In the dairy grazing system and in the beef systems, only 9.8 and 11.1% were efficient farms. The efficiency is generally higher in mixed systems than in dairy and beef systems.
