Determinação do valor financeiro dos recursos florestais madereiros da concessão da Levasflor

Abstract

The objective of the present work is to determine the financial value of the wood forest resources of the Levasflor concession based on forest inventory data carried out in early July 2005. To ensure sustainability, it was necessary to determine the allowable annual cut, for a cutting cycle 20 years old. The financial value was determined based on the financial criteria: net present value (NPV) and equivalent annual income (RAE). The discount rate chosen was 10% per year. A sensitivity analysis was carried out by varying the wood prices and discount rate by 25%. The permissible annual cut determined, in an area of ​​41097.8 hectares, was 14,912.18 cubic meters per year, from the 12 commercial species found in the Levasflor concession and 70% of the wood that will be harvested annually belongs to the species Brachystegia spiciformis. The financial value of timber forest products within 20 years is 15,261,195.15 US Dollars, which corresponds to an annual value of 1,792,574.26 US Dollars, assuming that all wood corresponding to the permissible annual cut will be sold within one year. Greater financial value is acquired when wood prices are increased by 25% (19,954,464.55 Dollars) and the lowest financial value is obtained when wood prices are reduced by 25% (10,567,925.75 Dollars). The 25% reduction and increase in the interest rate resulted in, respectively, 18,087,627.51 and }3.()84,430.00 Dollars. The results obtained allowed us to reach the following conclusions: The high annual cut volume is due to the large area that the concession occupies (49,000 hectares); the financial value of timber forest resources from the Levasflor concession is high, but it depends on the Brachystegia spiciformis market and is more sensitive to the variation in the price of wood than to the variation in the discount rate.
