Análise de rendibilidade de povoamentos de eucalipto e pinheiro bravo

Abstract

Mais de um terço do território de Portugal está ocupado com área florestal. Nas regiões centro e norte, esta é, maioritariamente, composta por povoamentos de eucalipto (Eucalyptus globulus Labill) e pinheiro‐bravo (Pinus pinaster Aiton). A forte tendência registada nos últimos anos, de substituição de povoamentos de pinheiro‐bravo por povoamentos de eucalipto, é normalmente justificada, pela perceção de mais célere retorno do investimento e pela maior rendibilidade que os povoamentos de eucalipto oferecem, face aos de pinheiro bravo. Este trabalho pretende assim analisar a rendibilidade destes dois tipos de povoamento, contribuindo deste modo para a compreensão do fenómeno. Neste trabalho são apresentados doze casos (quatro de eucalipto; quatro de pinheiro via plantação e quatro de pinheiro via regeneração natural). Os critérios financeiros utilizados nesta análise foram o VAL, a TIR, IR e PRCact. A aplicação destas técnicas, evidenciou que para uma taxa de custo de capital de 4%, todos os casos estudados se revelaram como boas opções de investimento. No entanto, a utilização de 8%, torna inviáveis os investimentos dos casos de pinheiro bravo via plantação. Os resultados alcançados no estudo estão em conformidade com a ideia generalizada, que os povoamentos de eucalipto apresentam rendibilidades superiores e períodos de retorno de capital inferiores aos dos povoamentos de pinheiro bravo. O estudo indica também, que a opção pinheiro bravo via regeneração não deverá ser negligenciada, principalmente, em situações de restrição de capital, uma vez que poderá ser a que permite a obtenção do maior rendimento para os investimentos realizados.

More than one third of Portugal 's area is forested. North and Center regions are mainly occupied by eucalypt (Eucalyptus globulus Labill) and maritime pine (Pinus pinaster Aiton). The high replacement pace of maritime pine stands by eucalypt stands registered in the past years, is usually justified by the perception that eucalypt stands provide faster return on investment and higher profitability. This work intends to analyse the profitability of these two types of stands, contributing to the understanding of the phenomena. Twelve case studies are analysed (four of eucalypt, four of maritime pine originated from plantation and four of maritime pine originated from natural regeneration). The financial criteria used are: NPV, IRR, PI, Payback period. The application of these criteria shows that to a 4% opportunity cost of capital, all the cases are good investment options. However, the use of an 8% rate, makes unfeasible the investment on maritime pine originated from plantation cases. The results of this study are in line with the general idea that eucalypt stands provide faster return on investment and higher profitability than the maritime pine stands. The study also shows that the maritime pine stands originated from natural regeneration option shouldn't be neglected, mainly when capital is rationed, as it could be the option that offers the highest net present value per dollar of initial outlay.
