CDA is a non-profit organization that helps national and international actors working in conflict-affected areas to improve the relevance, effectiveness, and accountability of their actions. CDA is widely recognized for its established expertise in the professional fields of Accountability and Feedback Loops, Conflict Sensitivity / Do No Harm, Peacebuilding Effectiveness, and Responsible Business. Our established expertise in those areas is rooted in our completed and current collaborative learning projects and extensive advisory work. Each of CDA’s foundational learning projects engaged hundreds and, in some cases, thousands of people, and has generated widely recognized and referenced lessons relevant to the policies and practices of international and local actors. Practitioner resources are available for free download on our website.
