Abstract
In the knowledge based economy building process, diasporas are seen as a development enabler. Thus we observe a growing interest of governments and international organizations in promoting and mobilizing diasporas knowledge networks, allowing them to contribute to national research and development activities in their countries of origin. In the mean time, diaspora organizations are growing and emigration of highly qualified at the highest rates ever reached in South America. Considering this situation as a starting point, this thesis was dedicated to observe dynamics of knowledge circulations between Europe and the Andean countries. In so doing, this thesis makes its point showing how the civil society, the origin countries and destination countries administrations share the diasporic space undertsood as the space of knowledge circulations. From this perspective we show that spatialization modes are different between systemic or spontanous initiatives. Thus, benefiting from andean and european experiences among civil society organizations we state that diasporas are both shared and split by their actors.
