Abstract
Previously published experiences and a survey among managers of industrial forest plantations in Brazil guided the development of a generalizable MCDA strategic model. This model was used to support the decision at the investment and management phases. The aim of the model is to support forest managers or investors engaged in the management of planted forests that provide wood for the pulp, energy, or solid wood industries. Using an open-source algebraic optimization modeling system (Pyomo), the development focused on adding model generation functions to the conventional matrix generation process. This system supports the analysis of different scenarios and a comprehensive set of evaluations regarding environmental and economic objectives. Specifically, the model focuses on the analysis of different management regimes and production cycles. It also explores whether managers should change species, mix them, or alter tree density or silviculture activities. It goes on to provide intervals for financial parameters that guarantee expected investment returns for investors. Two sample cases are presented: a four-thousand-hectare plantation of paricá trees, a fast-growing Amazonian native species (Schizolobium amazonicum) in the northern region of Brazil, and a thirteen-thousand-hectare eucalyptus plantation in the southwestern region of Brazil. Local yield curves, costs, market prices, and environmental goals are used to illustrate the cases. The first case is an example of an economically viable restoration process of a degraded Amazonian pastureland. It began in 2008, and a growth rate of 23 to 27 m3/ha/year was achieved. It has covered the degraded area with a dense canopy since 2010. On top of the environmental benefits expected from the conversion of a degraded pastureland into a densely forested area, the veneer logs harvested by the end of the paricá production cycle generated enough revenue to produce a profit for investors. The second case considers different prescriptions and silvicultural activities to deal with the multiple uses of eucalyptus plantations and the challenges companies face in solid wood markets, where customers expect the production of logs with different dimensions and properties
