The Broadband Strategies Toolkit ( was initially undertaken in two phases from 2010 through 2014, as a product of the ICT Sector Unit of the World Bank in close cooperation with infoDev ( with funding provided by the Korea Trust Fund on Information and Communication Technologies for Development. The initial work generated Modules 0 through 7. 

The Cross-Sector Infrastructure Sharing Toolkit was undertaken as a third phase from 2015 through 2017.  The core World Bank team for the toolkit included Peter Silarszky, Natalija Gelvanovska and Siddhartha Raja. Funding for the toolkit was provided by PPIAF, a multi-donor trust fund housed in the World Bank Group, which provides technical assistance to governments in developing countries.  PPIAF’s main goal is to create enabling environments through high-impact partnerships that facilitate private investment in infrastructure.  For more information, visit

A team from Macmillan Keck prepared the main body of the toolkit, while a joint team from Macmillan Keck and the Columbia Center on Sustainable Investment prepared 18 supporting case studies, including 15 business and project case studies and three country case studies.

The Columbia Center on Sustainable Investment is a joint center of Columbia Law School and the Earth Institute at Columbia University in New York City.  The Columbia Center is the only applied research center and forum dedicated to the study, practice and discussion of sustainable international investment, and has significant experience in shared use of infrastructure in developing countries.  The Columbia Center team contributing to this project included Perrine Toledano, Nicolas Maennling, Sophie Thomashausen and Chris Hunter.

We thank Richard Keck, who authored the main body of the toolkit based on over 31 years of experience with cross-sector infrastructure sharing.  He received valuable support and assistance in research, writing and editing from colleagues Rory Macmillan and Jason Blechman.  Chris Hunter of the Columbia Center provided invaluable support on the tedious and thankless task of cite checking and conforming citations.
