Organizations in the peacebuilding field face the imperative of taking a holistic, integrated approach to peacebuilding that combines traditionally distinct disciplines such as human rights, humanitarian assistance, sustainable development, environment, conflict resolution, security, and the rule of law in order to be effective in today’s complex conflicts. The concept of a Network of Effective Action is proposed as a set of practices for collaboration that is capable of facilitating integrated approaches to peacebuilding both on the ground and in terms of the theoretical development of the field.
