This report provides the supporting documentation for the Evidence for Peacebuilding evidence gap map, which was developed as one component of a joint initiative between 3ie, Innovations for Poverty Action, and the World Bank called Evidence for Peacebuilding. The evidence gap map is a key input into the scoping paper, which is the primary output of the stocktaking phase of the initiative. This report presents analysis of the evidence gap map alone; the scoping paper presents the analysis of the priority questions for future research based on the evidence gap map combined with the other inputs: portfolio review, stakeholder survey and stakeholder consultations.
