Os sistemas agroflorestais como alternativa econômica em pequenas propriedades rurais: estudo de caso

Abstract

The Agroforestry Systems have been considered as an alternative approach for the stability of the ecosystems and in the same time promote the efficiency and optimization of the natural resources in the production in an integrated form. The objective of this case study is the economic evaluation of agroforestry systems in the Pontal do Paranapanema region. The Agroforestry System being studied is formed by agricultural species: corn (Zea maiz), guandu bean (Cajanus cajan), carioquinha, (Vigna unguiculata), black (Phaseolus vulgaris) and cassava (Manihot esculenta) with forestry species: Eucalyptus citriodora, Eucalyptus camaldulensis. The economic evaluation was based on economical criteria such as Net Present Value (NPL) and Cost Benefict (C/B) for the annual agricultural culture, Land Expectation Value (LET) for the agroforestry component. The results showed that the agroforestry systems are economically acceptable to small farmers working in the same conditions presented in this study.
