This guide was born from a need to share learning from our experience in Central African Republic (CAR) from 2013–2015. During this turbulent period, CAR experienced unprecedented violence and brutality between the Seleka (Alliance) and the Anti-Balaka (Anti-Machete) militias. At the invitation of Muslim and Christian religious leaders, CRS trained more than 1,000 government, civil society, and private sector leaders in social cohesion principles and techniques, and equipped them with tools they could use in their workplaces and communities. This guide innovatively combines the 4Ds of Appreciative Inquiry ("Discover, Dream, Design and Deliver") with CRS’ 3Bs peacebuilding methodology ("Binding, Bonding and Bridging"). The result is a powerful approach for use within a people-to-people peacebuilding framework. Donors, host countries, and implementing partners who want to strengthen vertical and horizontal social cohesion, especially in fragile states, will profit from this guide. Each module offers detailed guidance on objectives, timing, steps, tools and notes for the trainer.
