Reintegration has never been, even at the best of times, an easy task; reintegration during an ongoing conflict presents even further challenges. By using lessons learned from both prior domestic processes and efforts from other corners of the globe, Colombia is trying to succeed in this endeavor. With reintegration as its central role, the Office of the High Commissioner for Reintegration (ACR) was established in 2006. At present the ACR attempts to reintegrate about 31,200 combatants, all over the country. In support of this Colombian initiative, the German Federal Ministry for Economic Cooperation and Development (BMZ), through the German Development Cooperation (GTZ) is funding BICC's work in advising the ACR. BICC's role is principally focused on finding a way to both monitor and evaluate the reintegration of thousands of demobilized Colombian ex-combatants.
