Intra-regional mobility is now an important factor in the development of states globally. African countries have not been left in this regard. Apart from the effort of the African Union (AU) in changing the narratives of brain drain to brain gain through the recognition of Africans in the Diaspora as the sixth region, there have also been concerted efforts to promote intraAfrican migration. Intra-African migration is an essential variable in the movement of goods, distribution of services, and increase in Africa's economic capacities. It has become more important with signing trade agreements such as the African Continental Free Trade Agreement (ACFTA) and Common External Tariff, as well as Regional Economic Cooperation’s free movement policies. However, despite the importance, increasing securitisation of migration is becoming a growing threat. Securitisation connotes that migration is perceived as an existential security threat to the host state and thus deserves at least control and stopping at best. The securitisation of migration has been evident in the case of South Africa's xenophobia cases, Ghana’s economic protectionism, and the case of Botswana and Zambia, among others. The constellation of these securitisations not only constitutes immigrants' vulnerability but endangers Africa’s development agenda, especially in the sphere of trade. The article offers a vivid perspective on the threats associated with migration securitisation within the context of Africa’s development agenda.
