This paper applies the cost-benefit analysis to the issue of participatory forest management (PFM) projects in Bangladesh. As economic incentive is the key factor to ensure farmers' willingness to continue in the PFM project, cost-benefit analysis of the project is very essential to understand the success of the project.
