he Peacebuilding Support Office (PBSO) was established to assist and support the Peacebuilding Commission (PBC) with strategic advice and policy guidance, administer the Peacebuilding Fund (PBF) and to support the Secretary-General in coordinating United Nations agencies in their peacebuilding efforts.
In the founding resolutions (A/RES/60/180 and S/RES/1645(2005)) establishing the Peacebuilding Commission, the United Nations General Assembly and the Security Council requested “the Secretary-General to establish, within the Secretariat, from within existing resources, a small peacebuilding support office staffed by qualified experts to assist and support the Commission”.
The Office comprises the Peacebuilding Commission Support Branch, the Peacebuilding Strategy and Partnerships Branch, and the Financing for Peacebuilding Branch.
