The AMI team focused on Work Package 4 (WP4) which pertains to the case of return migration between Morocco and Nigeria. We aimed to shed additional light on the unique circumstances of these two countries that influence migration dynamics in both regions. In addressing the main questions posed by WP4, we examined issues such as: What characterizes the governance of return migration between Morocco and Nigeria? What are the driving forces behind this governance? And how does the European Union's external migration policy shape the modalities of this governance? To provide comprehensive answers, we first gathered quantitative and qualitative data to assess the scale of return migration from Morocco to Nigeria. We also examined the political and operational frameworks facilitating and regulating these movements. As part of this effort, we analyzed the primary economic and socio-demographic characteristics of both Morocco and Nigeria. Additionally, we reviewed Morocco’s migration policy since 2013, including the actions and strategies implemented in recent years. Our data collection encompassed all available sources to support our analysis and respond effectively to the questions raised in WP4.
