Since its inception, PPIAF has distilled knowledge from over 1,300 technical assistance activities, other multilateral development banks, and from the private sector. This knowledge is freely available online, making best practices for delivering infrastructure through public-private partnerships accessible to all—at a scale and reach that cannot be achieved by individual interventions alone. PPIAF knowledge products have been widely used across the globe, improving welfare through private sector participation in infrastructure that is well-informed by experience, tools, and research. In April 2024, the Global Infrastructure Hub (GIH)'s expertise and resources were integrated into PPIAF, becoming its primary knowledge and data platform. This integration will enhance PPIAF's capacity to produce and disseminate global knowledge products, strengthen its support for country clients, and better incorporate global insights into World Bank Group country programs.
