The UN has attempted to evaluate the impact of its peace-building initiatives. In the early 2010s, the UN peacekeeping mission in Burundi sought to assess the success of its Disarmament, Demobilization and Reintegration program by counting the number of arms that had been collected, given the prevalence of arms in the country. However, these evaluations failed to include date from local populations, which are significant in impact evaluations of peacebuilding initiatives.
