    Impacts of rainfall shocks on out-migration are moderated more by per capita income than by agricultural output in Türkiye
    Rural populations are particularly exposed to increasing weather variability, notably through agriculture. In this paper, we exploit longitudinal data for Turkish provinces from 2008 to 2018 together with precipitation records over more than 30 years to quantify how variability in a standardized precipitation index (SPI) affects out-migration as an adaptation mechanism. Doing so, we document the role of three potential causal channels: per capita income, agricultural output, and local conflicts. Our results show that negative SPI shocks (droughts) are associated with higher out-migration in rural provinces. A mediated-moderator approach further suggests that changes in per capita income account for more than one quarter of the direct effect of droughts on out-migration, whereas agricultural output is only relevant for provinces in the upper quartile of crop production. Finally, we find evidence that local conflict fatalities increase with drought and trigger out-migration, although this channel is distinct from the direct effect of SPI shocks on out-migration.

    A Review of Transnational Migrant Entrepreneurship: Perspectives on Unequal Spatialities
    The spatialities of migrant entrepreneurship have changed dynamically in recent decades. Movements and exchanges transcend national borders more than ever, and transnational migrant entrepreneurship has become a burgeoning field of research. Yet, knowledge is dispersed across disciplines, and an understanding of contemporary spatialities is limited. We review 155 articles published in English, French, German, and Spanish since 2009, thereby providing an overview of existing knowledge on transnational migrant entrepreneurship and suggesting avenues for future research. We identify five current topical areas of research: (1) the business advantages of transnational migrant entrepreneurship, (2) the determinants of becoming a transnational migrant entrepreneur, (3) the transnational networks of migrants, (4) the economic impacts of transnational migrant entrepreneurship on home and host countries, and (5) whether local environments enable or deter entrepreneurial success. Building on our synthesis of the most recent literature, we propose three crucial dimensions which have been under-researched in past and current work, and which address the diversity of geographical locations, spatial connections, and spatial mobilities involved in transnational migrant entrepreneurship. Moreover, we put forward a set of questions for future research which will advance a comprehension of unequal opportunities among transnational migrant entrepreneurs.

    Linking climate change, environmental degradation, and migration: An update after 10 years
    (2021-11-1)
    In WIREs Climate Change, Issue 1(4), 2010, I suggested a typology of the data and methods used to assess links between climate change, environmental degradation and migration (Piguet, 2010). My review of the literature included publications up to 2009. Since then, the number of empirically based scientific publications on this topic has risen substantially to average 40 articles per year and the scope of methods, stock of results and diversity of questions has widened. Based on the CLIMIG database—a systematic and analytic collection of scientific references published on migration and the environment—this new synthesis provides a methodological typology of an exceptionally large number of published case studies. This will complement existing reviews and meta-studies and allow a global overview of the state of research by identifying consensus and disagreements, revisiting methodological challenges and mapping current and future research questions.

    Misleading claims about mass migration induced by climate change continue to surface in both academia and policy. This requires a new research agenda on ‘climate mobilities’ that moves beyond simplistic assumptions and more accurately advances knowledge of the nexus between human mobility and climate change.

    Human mobility is one response to climatic stress and shocks. In this synthesis article, we review the recent literature on the effects of climate change on human mobility within various disciplines. We explore key features of the interplay between climate change and migration, distinguishing between fast onset and slow onset climatic events, while taking into consideration causes of heterogeneity in migratory responses. Moreover, we shed light on the underlying mechanisms behind the nexus as well as the interplay between different means of adaptation. Based on our review, we identify gaps in the literature and present some general policy recommendations and priorities for research on climate-induced migration.

    The uneven geography of research on “environmental migration”
    Climate change and environmental hazards affect the entire world, but their interactions with—and consequences on—human migration are unevenly distributed geographically. Research on climate and migration have their own geographies which do not necessarily coincide. This paper critically confronts these two geographies by presenting the first detailed mapping of research in the field of environmentally induced migration. After a brief review of the geography of research on climate change, the paper presents an overview of nearly 50 years of case studies on the basis of CliMig, a bibliographic database of 1193 scientific papers and books on climate/environmental change and migration, among them 463 empirical case studies. We analyze the locations of these case studies, the academic affiliations of their researchers, and the origin of their funding. Mapping the locations of case studies worldwide points toward blind spots in the research and identifies “overstudied” areas. We describe the methodologies used in the studies and present a typology of environmental hazards. Our results show that research on environmental migration is mainly done in countries of the Global South, whereas climate science research in general is focused on countries of the Global North. We contend that the peculiar geography of environmental migration cannot be explained solely by the uneven vulnerability of southern populations to the environment. It must also be understood through the lens of post-colonial and securitization studies as the result of a framing of “environmental refugees” (and refugees in general) as an intrinsically “southern problem” and as a security risk for the North. This paper is an original contribution to the literature on the North-South divide in scientific research and will help to outline future directions of investigation.

    Back home or not?
    (2018-1-8)
    Post-disaster reconstruction in situ is potentially good as it allows affected populations to start a new life within their community. But what if people would have preferred to move elsewhere?
