摘要

O presente trabalho teve por objetivo fazer uma análise comparativa de viabilidade econ?mica de projetos florestais com Pinus taeda e Eucalyptus dunnii localizados no município de Prudentópolis, PR. Na análise econ?mica foram utilizados os critérios do Valor Presente Líquido (VPL), Raz?o Benefício Custo (B/C), Taxa Interna de Retorno (TIR) e Valor Periódico Equivalente (VPE). A taxa de juros usada foi de 6,75% ao ano. Para o projeto de Pinus taeda os dados de custos e receitas corrigidos totalizaram R$ 4.344,71/ha e R$36.143,99/ha, respectivamente. Os valores calculados dos critérios de avalia??o econ?mica foram um VPL de R$31.799,28/ha; Raz?o Beneficio/Custo de 8,32, TIR de 27.23% e VPE de R$ 3.200,87/ha/ano. Para o povoamento de Eucalyptus dunnii, a corre??o dos valores para o momento zero totalizaram R$ 5.767,75/ha, de custos e R$43.842,46/ha de receitas. Os valores calculados dos critérios de avalia??o econ?mica foram um VPL de R$ 38.074,71/ha; Raz?o Beneficio/Custo de 7,60; TIR de 35,83% e um VPE de R$ 3.832,55/ha/ano. Para os dois projetos foi realizada análise de sensibilidade do VPL. Os resultados mostraram que ambos os projetos s?o economicamente viáveis.Palavras-chave: Análise comparativa; viabilidade econ?mica; custos; receitas.?AbstractComparative analysis of the economic viability of Pinus taeda and Eucalyptus dunnii plantations in the south-center region of Parana State, Brazil. The objective of this research was to carry out a comparative analysis of economic viability of afforestation projects with Pinus taeda and Eucalyptus dunnii located in Prudentópolis County, State of Paraná, Brazil. In the economic analysis the criteria of Net Present Value (NPV), Benefit Cost rate (B/C), Internal Return Rate (IRR) and Periodic Equivalent Value (PEV) were used. The interest rate used was of 6.75% per the year. For the Pinus taeda plantations the data of rectified costs and income totalized R$ 4.344,71/ha and R$ 36.143,99/ha, respectively. The calculated values of the of economic evaluation criteria presented a NPV of R$ 31,799.28/ha, a Benefit Cost rate of 8,32, an IRR of 27.23% and a PEV of R$ 3.200,87/ha. For the Eucalyptus dunnii plantations the rectified values totalized R$5.767,75 and R$43.842,46/ha for the costs and income, respectively. The calculated values of the economic evaluation criteria showed a NPV of R$38.074,71/ha, a Benefit Cost rate of 7.60, an IRR of 35,83%, and a PEV of R$3.832,55/ha. A sensitivity analysis of the NPV for the two plantations was carried out. The results showed that both afforestation projects are economically viable.Keywords: Comparative analysis; economic viability; costs; income.
