This study compared the forest planning of outgrower schemes projects with own areas of forestry companies´ areas. The total area of the companies was 41,178 ha distributed in 299 stands, and the outgrower areas were 2,445 ha distributed in 144 properties. The planning involved linear programming of areas in order to maximize the equivalent annuity (EA), under the condition (constraints) of a regulated structure at the end of planning. Two scenarios were evaluated: a) individual model - areas of outgrower schemes and companies in separate models, and b) single model - areas of outgrower schemes and companies in the same programming model. The EA difference of the individual to the single model was unfavorable to outgrowers, since it reduced its value by 14%. In the companies´ areas, the solution of the single regulation was favorable, increasing the EA in approximately 1%. It was also verified in a new scenario of the single model that if the wood of outgrowers were sold by stumpage, the global EA of these areas would increase by 0.9%, thus more attractive to landowners.Downloads
