Colombia has one of the longest-running armed conflicts in the world. This briefing paper draws on Oxfam's research in Colombia in late 2011 into the impacts of Colombia's stabilization programme, the National Consolidation Plan (NCP). Interviewees clearly indicated that the NCP and other stabilization efforts had failed to make communities more secure, often leaving them less safe. Severe limitations were also found in the attempts to promote conflict-sensitive development. The United States is one of the leading donors to the NCP, along with Spain and the Netherlands.
