Conclusion Additionally, international actors should continuously monitor and evaluate the effectiveness and efficiency of their engagements, and adjust them to changing conditions on the ground. Robust monitoring and evaluation should include an assessment as to whether responsibilities can be handed over to local actors in a sustainable manner. The engagement of international actors like the OSCE in building sustainable peace and democracy requires a long-term perspective and a comprehensive approach. Patience and perseverance are as important as prudent planning and foresight. This is related to both the support needed now as well as to assistance that could be required in the future. The OSCE’s experiences in South-Eastern Europe entail many good practices and lessons to be learned for the future peacebuilding efforts of international actors and their local partners. This reference guide hopes to serve as a source of inspiration for interested stakeholders in building sustainable peace and democracy across the OSCE area. 108
