The impact of international migration, both South-South as well as South-North, on the economic, social and political life of the people in Eastern and Southern Africa [was] not well documented and studied," and "the evidence-base for policy on migration and development [was] very weak." With this in mind, OSSREA's invitation to conduct a study on international migration in Africa had the following objectives: To analyze the nature and type of South-South migration, focusing on issues, such as brain gain and/or brain drain, remittance flows, technical knowhow transfers, violations of the right of African migrants and gender dimensions of migration; To investigate the dynamics of migration from Eastern and Southern Africa to the Arab Gulf States as well as to developed countries, focusing on the skills of migrants, brain gain and/or drain, remittance flows, technical know-how transfers, violations of the rights of African migrants and gender dimension of migrants; and to assess the successes, impediments and challenges of African international migrants from Eastern and Southern Africa and to formulate policy recommendations to maximize the gains and minimize the costs associated with international migration in Africa.
