Conteúdo: |
Spatial and environmental constraints in forest management optimization problems have become a challenge to researchers working with forest management planning optimization models, mainly because of the combinatorial nature of these problems. Forest managers in Brazil are often faced with the need to connect native forest fragments through the management of the landscape that surrounds them. The objective of this article is to develop a mixed-integer linear programming model that guarantees minimal connectivity among fragmented natural areas while maximizing the profit or the production of the managed industrial forest plantations. The corridors are formed by industrial forest stands with specific characteristics defined by the forest manager. In this article, connectivity among fragments was inserted as a Steiner net in a type I harvest-scheduling model. The resulting net formulation has an integer number of origins, destinations, and arc capacities, which allows for the basic variables to produce integer values, even when variables defining flows in each arc are defined as continuous. For the case study, the opportunity cost of creating the corridors was estimated at approximately 0.051% of the objective function value obtained for the model without connectivity. FOR. SCI. 59(6):661– 669. |
