| Approximately four thousand hectares of degraded pasture land in the Brazilian State of Par á in the Amazon have been converted to a forested area since 2008. A single fast-growing native tree species was used in the process, the paric á (Schizolobium amazonicum). Paricá grows at a rate of 23 to 27 m3/ha/year and densely covers the degraded area with its canopy in approximately 2 to 3 years. Besides the improvement in terms of environmental indicators, the paricá plantation offered reasonably good income when sold for veneer logs. A generalizable model was developed to support important decisions about to be made by the forest management team. A multi-objective model was developed, using an open source algebraic optimization modelling system (Pyomo). The systems allowed the analysis of different scenarios and a comprehensive set of evaluations regarding environmental and economic objectives. Specifically, the model helped on supporting the analysis of different management regimes and production cycles, and whether managers should change species, mix them or alter tree density. It also provided price ranges that guarantee expected investment returns for the investors. Examples were provided using local yield curves, costs, market prices, and accomplished environmental gains. | |
