Presentation 1

A Bioeconomic Approach to Sustainable Forest Management in the Colombian Amazon

Jorge Marco, Yuli Castellanos

Discussant: Matthias Bösch (Thünen Institute)

In Colombia, Sustainable Forest Management (SFM) has been recognized as an approach to prevent deforestation while supporting the livelihoods of forest-dependent households. However, timber harvesting of natural tropical forests currently operates as a subsistence activity, generating low income and negative impacts on ecosystems. This study develops a discrete time bioeconomic model for SFM, with an objective function focusing on the biological and economic implications of timber extraction for three high-valued commercial species, Achapo (Cedrelinga cateniformis), Cabuyo (Eschweilera coriacea) and Dormidero negro (Parkia discolor), located in the Guaviare region (Colombian Amazon). Our results show that the maximum benefits from sustainable forest harvesting of the three species are achieved in a 25-year span, with net benefits per hectare of USD 507.8, for a planning horizon of 50 years. Sustainable forest harvesting was found to be robust with respect to a number of assumptions in the model. These results provide a technical basis for harvesting authorizations and permits. Policy implications are discussed.
