The impact of violence on development too often remains ignored by those who have the possibility to act on it. This document makes the case for increased attention by international development agencies to violence prevention. A key aim is to stimulate dialogue on the role of international development agencies in the prevention of violence globally and to increase investment in a commonly agreed set of applied violence prevention strategies. The primary audience for this document is policy-makers, high-level planners, and others in the international development field. It will be particularly useful for those with decision-making authority in setting the international development agenda, and those who influence and shape donor policy.
