Economical analysis of silvopastoral systems with paricá (Schizolobium amazonicum Huber) in the northeast of Pará, Brazil. Zootecnia Trop. [online]. 2008, vol.26, n.3, pp.403-405. ISSN 0798-7269.

The use of silvopastoral systems has been indicated as an alternative use for the recovery of degraded areas in the Amazon region. In the northeast of Pará, Brazil, producers have used grazing in forest plantations, especially paricá (Schizolobium amazonicum Huber), with pastures of Brachiaria humidicola being used by cattle. The aim of this study was to analyze economically this silvopastoral systems (SPS) compared to forest monoculture (FM) using economic indicators: Internal Rate of Return (IRR) and Net Present Value (NPV). The results conclude that the SPS is economically more attractive than the FM. Thus, the adoption of such systems must be stimulated in the region as an overcome activity of the FM.

Keywords : silvopastoral system; financial analysis; internal rate of return; net present value.
