Análise de viabilidade econômica de um sistema agroflorestal localizado no município de Parauapebas-PA

Abstract

The agricultural model implemented in the Amazon Region in the last decades is the result of governmental programs of colonization, which encouraged deforestation and, consequently, changes in the way of exploitation and use of natural resources, anthropic activities extremely harmful to the sustainability and conservation of ecosystems. The southeastern region of Pará has cattle farming and mining as its main economic activities. In Parauapebas, due to the exploitation of iron ore by the former Companhia Vale do Rio Doce, the current Vale, through the Grande Carajás Project, provoked an ungoverned territorial expansion. As an alternative to combat degrading practices developed in the region, there are agroforestry systems (SAFs), which can be defined as the integrated use of land for forestry, agricultural and / or livestock production purposes. Thus, considering that the southeastern region of Para, especially the municipality of Parauapebas, does not have much information about agroforestry systems, this work aims to identify if they are economically viable alternatives for farmers in southeasternPará. For the analysis of the data was used to Amazon SAF version 4.11. The following economic viability indicators were calculated: net present value (NPV), internal rate of return (IRR), benefit / cost ratio (RB / C) and payback. From these, it was found that the inputs were responsible for the higher costs in the system. Despite the high expenses the cajá was the one that presented the greater profit followed by the cupuaçu. In this way it can be seen that the indicators presented prove that this activity is economically viable
