Programs with regional or global reachare increasingly being used to channel funds to specificdevelopment needs, reflecting the emergence of new fundingsources and in some cases donor distrust of the establishedmultilateral development model to deliver global goods.Evaluating the contribution of these programs is importantto understanding whether their relevance and effectivenesslive up to their promise and how they contribute to the newaid architecture. This is third biennial report of theIndependent Evaluation Group (IEG) on the World Bankapos;sinvolvement in global and regional partnership programs(GRPPs) since the conclusion of IEGapos;s two-phaseevaluation on this topic in 2004. The first two biennialreports were discussed at the committee on developmenteffectiveness subcommittee in May 2006 and March 2008. Thepresent report is the first one that will be disclosed tothe public reflecting the growing maturity of this line ofIEG's work. This report has been based on the first 17GPRs that IEG has completed and on interviews with Bankstaff who have been involved in the management and oversightof GRPPs in central, network, and regional VicePresidencies. IEG greatly appreciates the time and insightsprovided by those interviewed for this report, includingnetwork and regional staff who confirmed the accuracy of thebasic information provided in the appendixes to this reporton the nearly 120 GRPPs with which the Bank is currentlyinvolved. The objectives of the 17 programs that IEG hasreviewed in depth since 2006 have been highly relevant interms of collectively addressing important global andregional issues, but few have had a well-articulated resultsframework. Almost all programs can point to some positiveachievements in terms of outputs. However, thesustainability of a number of programs and the benefits theyfoster is threatened by weak resource mobilizationstrategies, failure to keep up with the changing global andregional context, and difficulties in demonstrating resultsat the outcome level.
