Assessment of the sustainability in dehesa farms according to size and livestock prevalence
This paper presents an evaluation of the sustainability of the dehesa livestock systems located in Extremadura
(SW Spain). We apply a methodological adaptation of the framework known as MESMIS (Framework
for the Evaluation of Management Systems incorporating Sustainability Index). This method
is based on the valuation of basic attributes of sustainability using indicators and indices that allow
simultaneous and comparative analyses of farms based on their size and productive orientation. A
global value of sustainability for each typology present in dehesa is obtained from a fundamentally
technical-economic perspective, taking into account some environmental and social aspects. The
dimension of the operation influences the capacity of adaptation of operations, with bigger farms
showing better adaptability. The smaller farms compensate their management by improving productivity
levels. We also observe that the presence of Iberian pig improves the sustainability index of the
operations.
