Academics and policymakers have been paying close attention to the impact of climate change on migration in recent years. This phenomenon piqued interest because the factors driving environmentally induced migration are complex and manifold. Noticeably, there has been considerable scholarship on climate change and migration in Africa. However, there has not been a concerted effort to periodically review the existing literature to systematically document the state of scholarship. Using a standardized systematic review procedures to analyze 22 peer-reviewed studies published between 2000 and 2022, we found that climate change impacts migration in many complex and multilayered forms. Beyond what has already been established in the literature on climate-related migration such as environmental effects on migration; migration as an adaptation strategy; and the influence of environmental and non-environmental factors on migration; we also found that (1) studies on climate-induced migration in Africa intensely focused on SSA, suggesting an uneven study of the region, (2) heavily affected people tend to be immobile, and (3) young people have high migration intentions due to harsh climate insecurities. These findings require urgent government and stakeholder attention. Specifically, there is a need for scholarship to interrogate the climate change–immobility nexus in order to design appropriate in situ or ex situ adaptation strategies to support lives and livelihoods.

As global economies become increasingly interconnected, the movement of people across borders has intensified, generating significant debate on the implications for both sending and receiving countries. Amid this debate, studies continue to report the return of some migrants to out-sourcing countries. While extra-regional return migration (henceforth, return migration) to Africa has received scholarly attention, there is no periodic systematic literature review to establish emerging themes on this topic. In this paper, we use standard procedures to analyse twenty peer-reviewed articles published between 2000 and 2022. From the findings, it emerged that return migration is a complex process shaped by multiple factors, such as family considerations and policies. The findings also highlight the differential experiences of returnees as they reintegrate into life in their home countries. Therefore, stakeholders should provide the necessary policy support to enhance the contributions of returnees to development.

Diaspora-homeland engagements, also known as diaspora policies or sending state strategies, have received significant attention in research and policy. This study applied framing theory and textual analysis to 110 Ghanaian online newspapers to examine how the media framed Ghana's 2019 Year of Return. The analysis revealed that the media predominantly framed the Year of Return from an instrumental perspective, buttressed by the frames of tourism development; economic development and investment; and branding and marketing. In contrast, a few discussions framed the event through a feminist ethics of care lens, emphasizing the need to foster strong emotional bond between diaspora populations and the homeland (Ghanaian hospitality). These frames reflect the state's approach to engaging the diaspora community. The policy implications of this study are also highlighted.
