Of course, the exact definition of peacebuilding varies depending on the actor, with some definitions specifying what activities fall within the scope of peacebuilding or restricting peacebuilding to post-conflict interventions. Even if peacebuilding has remained a largely amorphous concept without clear guidelines or goals, common to all definitions is the agreement that improving human security is the central task of peacebuilding. In this sense, peacebuilding includes a wide range of efforts by diverse actors in government and civil society at the community, national, and international levels to address the root causes of violence and ensure civilians have freedom from fear (negative peace), freedom from want (positive peace) and freedom from humiliation before, during, and after violent conflict.
