As a global platform for knowledge, PPIAF offers clients a way to leverage best practices on public-private partnerships in infrastructure from every region of the world. PPIAF develops new knowledge through research and helps make existing knowledge accessible through its library, which includes PPIAF publications, PPIAF-funded reports, books, short notes, case studies, lessons learned, and other resources. The most useful PPP Resources in English and French are also available in the Library. To access all the PPIAF Annual Reports click here.
