Conteúdo: 	In central Brazil, a large area originally covered by savanas (the cerrados) is currently exhibiting signs of degradation, which jeopardises the sustainability of crops and beef-producing systems. Agropastoral systems have been advocated as na important alternative that can provide sustainability to the region. Following this assertion, twelve systems (six including crpo-pasture rotation) have been studied in log-term research performed at EMBRAPA-CNPGC. Based on the preliminary results, the economic performance of six of the systems has been analyzed. Cash-flows from october 1993 to May 1999 were delineated, based on a partial budget procedure where the current system, based on sown pasture only, is suffering from degradation. The six systems show positive net present values; that is, the extra benefits are greater than the extra costs (in relation to the degraded system). The three highest values correspod to the two alternatives with no crops and the one where pasture and maize are jointly sown. Nevertheless, these results must be interpreted with caution. The planning horizon is not long enough to take into account the complete consequences of crop-pasture rotation, e. g. the long-term effects of fertilizers and the full utilization of areas under pastures. Furthermore, the concept of sustainability requires a multiple criteria approach including, besides the economic aspects, the social and environmental impacts of the new alternatives. Finally, changes in the systems are constrained by cultural factors, management skills, and capital/machinery availability. All these points must be included in further analyses, which should be carried out with the complete set of experimental data.
