Collective Impact in Peacebuilding: Testing a new model

Project Overview

CDA has been investing in developing collective impact​ as a new model for peacebuilding. This work builds on years of experience working on peacebuilding effectiveness, as well as lessons emerging from 16 “cumulative impact” case studies that investigated how multiple peacebuilding efforts “add up” to progress towards sustainable peace. As part of a project supported by Humanity United, “Collective Impact for Peacebuilding: Testing a new model,” CDA produced a “Framework for Collective Impact in Peacebuilding.”

We are currently conducting additional case studies examining the role and effectiveness of peacebuilding networks and coalitions towards achieving greater impact on country conflict systems. The findings of this current phase of learning on collective impact will be published by the end of 2018.

Project Funders

The primary aim of this project is to document and learn from the experiences of collective impact efforts by formal and informal networks and consortia in peacebuilding to develop further insights about multi-stakeholder initiatives.


Each case study will be developed through interviews with network members and support organizations, as well as by critically engaging with other actors, commentators and observers familiar with the context and the work of the network. Cases will also draw from both primary and secondary sources.

CDA will conduct several regional consultations and produce a final report that draws on all of the retrospective and prospective cases, presenting findings, key lessons and, most importantly, a further elaboration of the framework benefiting from the evidence and field experience of its application and adaptation.
