Relying on micro-evidence on the repercussions of civil conflicts, this edited book explores theories and policies of post-conflict peacebuilding. Reconsidering existing knowledge on the civil conflict and peacebuilding processes in particular, it empirically presents the relationships between conflict dynamics and citizens’ norms, values, and preferences in the post-conflict context. Once it occurs, civil conflict brings enormous suffering on the local society. As a consequence of wartime coercion and violence that tear it apart, citizens come to harbor fear, distrust, and hatred of others, especially of those who are in different sociopolitical groups. This can significantly alter the pre-conflict norms and values of the citizenry and make reconciliation difficult across groups in the aftermath of the conflict. To tackle these problems, post-conflict peacebuilding should be well designed so that it can widely cover and sufficiently deal with conflict-affected citizens. This approach urges us to pay serious attention to the individual-level impact of the conflict process and dynamics. The importance of micro-level analysis does not disregard that of normative and/or macro-level approaches to the development of peacebuilding policies. However, the micro-level approach is better able to capture wartime civil–military relations that largely vary between individuals. The book is aimed at linking academic knowledge with policy development in peacebuilding. To reflect existing policy frameworks in peacebuilding, the implications of micro-evidence-based studies for conflict-affected societies are discussed here. A bottom-up approach pursued throughout this book allows us to elaborate desirable policy schemes for peacebuilding that conform to local contexts.
