We are pleased to invite all members of CALACS that are interested in migratory dynamics to join our Working Group. Studies on Migrations and Diasporas are interdisciplinary by definition because they must be informed by sociological, anthropological, demographic, historical, economic, political, geographical, and environmental considerations. The Working Group on Migrations and Diasporas of CALACS provides an exceptional opportunity for collaboration and exchanges between researchers who share common interests - for example, around a country, a phenomenon or a specific period - with the contribution of a diversity of disciplinary, conceptual and methodological perspectives.
