Abstract

Regional forest management policies such should be evaluated appropriately to avoid unintended effects. The local government of the study area have impelled forestry enterprises to plant after clear-cutting inside the “zone to promote planting (zone)” since 2017. This study analyzed the differences of clear-cutting tendencies between inside and outside the zone with respect to area and locations. We calculated ATT (average treatment effect on the treated) by a statistical causal inference method: an inverse probability of treatment weighting method with propensity score. Forest age, slope degree, and distances from roads were used as covariates. As a result, ATT was -0.22%±0.11%, which means clear-cut had been avoided inside the zone compared to outside. Quantitative analysis of policy impacts, as done in this study, is fundamental for EBPM (evidence-based policy making) and sustainable forest management.
