Conceptualizing climate-induced migration in Africa

Abstract

Climate change has detrimental effects on the livelihoods of Africans, given their dependency on agriculture and subsistence farming. As such, when the environment is no longer conducive due to climate change challenges, migration is opted to seek better, more supportive living conditions. The study aimed to understand migration trends in the African region and to identify sustainable development strategies to mitigate migration by employing a bibliometric and systematic literature review. This systematic literature review of 16 studies conceptualized climate-induced mobility in African countries with evidence on how climate change has influenced migration decisions for most dwellers in vulnerable African areas. The results revealed a rural-urban migration as farming workers searched for other ways to secure livelihoods. Migration to other countries was also identified, especially in countries like the United States, France and the United Kingdom. However, the results also revealed that those who remained in rural areas would opt for other livelihood activities such as businesses. It was also observed that climate-induced migration is growing in Africa, particularly in Ghana, Uganda, Tanzania and Ethiopia. Therefore, to mitigate climate issues and manage migration, strategies are required to support communities affected by climate-induced problems. This study recommends that governments and policymakers should consider strategies like climate development finance, capacitating communities depending on natural resources, conservation agriculture and innovative technology to help stabilize the economies in areas affected by climate change and to improve human security.
