With support from the Bertelsmann and the Hewlett Foundation, TPI undertakes a major study of diaspora philanthropy – best practices, methods for promoting diaspora philanthropy, etc. TPI is then retained by “Give 2 Colombia,” a US-based public charity committed to encouraging and facilitating disaspora giving by Colombians in the US, to assist in the design and delivery of a two-day conference on achieving greater impact and reach in this effort.
