This strategic review report, prepared by James Adams, assesses the development impact and effectiveness of the Pacific Region Infrastructure Facility (PRIF) and provides suggestions on potential future directions of this organisation. This work was carried out by consulting with PRIF Members and other stakeholders on a range of key strategic issues. Consolidated into its present organizational arrangements in 2013, PRIF has established a clear record of performance. Its membership has expanded and now almost all major donors to Pacific infrastructure are Members. A central focus of its efforts has been its work on improving donor cooperation across the Pacific. Holding regular meetings with key Pacific donors and developing and expanding a network of Sector Working Groups (SWGs) that cover all key infrastructure topics, the PRIF framework has ensured that donor behaviour is more consistent and constructive in the Pacific. Duplication of work has been reduced, opportunities for joint work have been identified and exploited and a more open and cooperative donor environment has been established. This report concludes that in its totality this work qualifies as a “best practice” in respect to aid effectiveness in low-income countries.
