In the second contribution to Part Three, the UN’s Multi-Partner Trust Fund Office writes a coming-of-age story on the UN pooled fund mechanism. It traces the evolution of the concept of pooled funding from its inception in 2004 to a mechanism which has a central role to play in making the current UN reform a success. While aggregate trends are positive, funding to pooled mechanisms is largely restricted to a handful of contributors. The paper makes the case that, in order for a quantum leap in funding to take place, a corresponding leap in quality is needed.
