Countries in South America have a long history of engagement with their nationals abroad. This repository seeks to compile and categorize some of the most promising practices developed during this history to facilitate exchange and cooperation among actors in the region. Regional cooperation in South America in this sense has great potential given that South American transnational communities share many linguistic and historical commonalities and in some destination countries they organize themselves and work not only with their compatriots but also with the broader Latin American community. With more than 40 examples of practices organized by the type of contribution the practice facilitated and by the country in which it was developed, it is hoped that this document will be a tool to inspire governments, civil society, and other relevant actors to take the initiative to empower their diasporas as full participants in the development of their countries and communities of origin.
