This study evaluates the effects of the National Policy for Territorial Consolidation and Reconstruction (PNCRT) on security in the regions affected by the armed conflict. It focused on analysing its effect on life threats, infrastructure damage and the spread of illicit crops through a combination of statistical techniques called Propensity Score Matching and Difference in Differences. Its premise is based on the idea that the execution of the policy of peace and institutional strengthening would significantly improve security conditions. Indeed, results indicate that the PNCRT has succeeded in improving various security indicators in the regions where it was implemented, except the eradication of illicit crops.
