Codevelopment is a trend of thought and a development strategy in development studies which considers migrants to be a developing factor for their countries of origin.
Although it is widely accepted that it was French scholar Sami Naïr who first coined the word codevelopment, it is believed this phenomenon has existed alongside migrations since they exist. Traditionally, immigrants (especially those who migrate for economic reasons) have, collectively or individually, supported their communities of origin.
In 1997 Sami Naïr, while directing the Interministerial Mission on Migration/Codevelopment, defined this last concept as a proposal for integrating immigration and development in a way that migration fluxes will benefit both the country of origin and the country of destination. This is, a consensual relationship between two countries that will allow migration to the country of destiny not to imply an equivalent loss in the country of origin.
Adherents to this model believe that it fosters mutual collaboration among countries in a way that traditional and hierarchical north-south development focus did not. In this context, immigrant initiatives enrich the countries of origin both from a cultural and a human resources perspective. Their condition as transnational citizens would allow them a better understanding of the needs of both the communities of origin and destination. For this reason, their participation in projects involving members of their communities, in both “their” countries would be more effective, as priorities and needs would be correctly identified. On the other hand, this participation would also work as an integrating force in the destination countries, as they would be perceived as an enriching factor by the public opinion and institutions.
