Sustainability of Livestock Systems in the Pampa Biome of Brazil: An Analysis Highlighting the Rangeland Dilemma

The objective of this study was to analyse the sustainability of different livestock systems in the Brazilian Pampa biome, from the perspective of the rangeland dilemma. We used the indicator-based framework for evaluating the sustainability of natural resource management systems (MESMIS). These were constructed for social, economic and environmental dimensions, and they were measured across a study suite of 115 establishments, representing the rangeland livestock system (RLS), intensive livestock system, and livestock–agricultural system (ALS). Indicator averages were compared between three systems via ANOVA and Tukey test. The results allocated a higher level of sustainability to RLS. When the three land-use systems were analysed across the dimensions, significant differences were found in their environmental sustainability, with the ALS presenting poorer results. Within each dimension, there were significant differences in the indicators for production systems, social participation and capital flow. We discussed two main points: the results found through the concept of the rangeland dilemma, by exploring its conditions, in addition to exposing the concept of functional integrity. In conclusion, an approach to develop policies for the Pampa is to recognize the rangeland as a “common good”, to generate income and stimulate the local economy.
