The Effective Peacebuilding Initiative identifies, analyzes, and promotes interventions proven to prevent and resolve armed conflict. Our data-driven approach transforms how organizations and policymakers build lasting peace.

War affects nearly every aspect of life, from development and public health to education and the environment.
This lack of clarity affects real people. Conflict continues to displace families, fuel hunger, weaken education, and undermine economies. These costs reduce human welfare and prevent millions of people from reaching their full potential.

We know the human and economic costs of war. The critical gap in peacemaking is not passion or effort. What is missing is clear and accessible guidance on what helps prevent violence and what supports efforts to resolve conflicts already under way.

We equip funders, practitioners, and policymakers with evidence-based guidance they can use to reduce the harms of armed conflict. We build a strong and credible body of knowledge, support those working in the field, and promote decisions that are informed by evidence. Our goal is to help people act with clarity, confidence, and impact.


In fields like public health, education, and humanitarian response, clear evidence-guided practice has become the norm. Peacemaking has never had anything comparable at scale. EPI works with partners to bring this level of clarity and practical guidance to the people working to reduce violence.
