BACKGROUND Despite an increase in scholarly and policy interest regarding the impacts of environmental change on migration, empirical knowledge in the field remains varied, patchy, and limited. Generalised discourse on environmental migration frequently oversimplifies the complex channels through which environmental change influences the migration process. OBJECTIVE This paper aims to systematise the existing empirical evidence on migration influenced by environmental change with a focus on Africa, the continent most vulnerable to climate change. METHODS

In the past few years, governmental agencies have developed a diverse repertoire of migration-management measures to steer migration flows and discipline unwanted migration. Migration-information campaigns have become a prominent tool aimed at communicating directly to migration aspirations of the targeted population in transit and sending countries. Through these information campaigns the geographical locus of control is shifted toward where the receiving state seeks to steer migration flows. This review paper is a research synthesis on literature engaging with migration-information campaigns. The study is based on 17 peer-reviewed journal articles from the years 2010-2020. Articles were coded based on discipline, type of research, research perspective, geographic origin and focus of the campaigns, objectives and rationale of the campaigns, tools and methods used in those campaigns, campaign funding, actor constellations, and a general assessment of each article.Findings from this study identify prominent trends as well as blind spots in the current research and indicate that there is still little research available on information campaigns concerning irregular migration, and even fewer studies report on their effectiveness. By implication future research is ad-

Place-based research faces multiple threats, including both natural and global health hazards and political conflicts, which may disrupt fieldwork. The current COVID-19 pandemic shows how these threats can drastically affect social-ecological research activities given its engagement with different local stakeholders, disciplines, and knowledge systems. The crisis reveals the need for adaptive research designs while also providing an opportunity for a structural shift towards a more sustainable and inclusive research landscape.

Migration-information campaigns informing potential migrants about the risks of the journey and the harsh life conditions in the destination countries have emerged as prominent tools of migration management in the last decades. Despite their growing importance, little is known about their local implementation in countries of transit and origin as well as their influence on potential migrants' perceptions and experiences. The central objective of this paper is to understand how migration-information campaigns are implemented on a local scale and how they shape the perception and discourses of migration in the region. We pursue a multi-scalar analysis of international migration management policies and their outcomes in a specific place and link them with local migration aspirations. The paper is based on qualitative empirical research carried out in Harar, a medium-sized city in the Harari regional state of Ethiopia.Drawing on interviews with government officials, NGOs, city dwellers, and return migrants, as well as the analysis of policy documents and scientific literature, we show how the local implementation of migration-information campaigns shapes the local perceptions and discourses on migration within which migration aspirations are embedded. We found that information campaigns did not take into account the complexity and multifaceted nature of local socioeconomic
