“…Instead of looking at internal and international migration patterns as if they were two distinct phenomena, there are also studies that claim a direct connection between internal (mainly from rural to urban areas) and international migration [55]. The main argument is that rural populations affected by climate shocks first move into cities, raising urbanization rates and exacerbating social-economics conditions.…”

This paper proposes a selective review of the classical economics-based literature on climate change and migration, focusing on the extent to which agriculture might be considered a key mediating channel linking climate change to migration. Overall, climate change is expected to have large and negative effects on the global economy. These effects are even more evident whenever the economic sector considered is the agricultural one, particularly in developing countries. Hence, migration can be viewed as a specific form of adaptation implemented by individuals and households, enabling them to cope, among other things, with weather-induced risk. We show that the importance of agriculture emerges from both plenty of micro-level country studies and relatively few macro-level analyses using cross-sectional data over longer time periods. Thus, policy actions targeted to sustainable agriculture and rural development can both help tackle the challenges posed by climate change and create opportunities in the face of growing migration issues. However, we also stress that much of the current evidence is based on statistical associations that have nothing to do with causal inferences. This calls for the use of a more structural approach and more sophisticated research designs, enabling the researchers to better discriminate among different mechanisms concurrently at work. In addition, further research should be addressed to the role played by food security, a complex dimension largely missing in the current debates on climate change and migration.

“…On the contrary, Marchiori et al (2012) and Coniglio and Pesce (2014) identified an effect on net flows using annual data. Table A.2.c in the Online Appendix shows that emigration rates decrease with population size and increase with the number of natural disasters and with temperature shocks when using data in 5-year intervals.…”

International migration is an important determinant of institutions, not considered so far in the development literature. Using cross-sectional and panel estimation for a large sample of developing countries, we find that openness to emigration has a positive effect on home-country institutional development (as measured by standard democracy indices). The results are robust to a wide range of specifications and identification methods. Remarkably, the cross-sectional estimates are fully in line with the implied long-run relationship from dynamic panel regressions.

“…This holds true for Marchiori et al (2012), who find that weather anomalies may cause both internal and international migration in Sub-Saharan Africa. However, other studies show that seasonal and circular migration are more common than international mobility in the case of environmental shocks.…”

“…For instance, Reveuny and Moore (2009) found that environmental degradation, including both storms and land scarcity, increases out-migration. Other studies showed that weather anomalies measured through long-term deviations of rainfall and temperature are a migration determinant in Sub-Saharan Africa (Barrios et al, 2006;Marchiori et al, 2012). Beine and Pearsons (2014) are interested both in long-term environmental factors with the use of rainfall and temperature data and short-term variables measured through natural disasters.…”

Terms of use: Documents in AbstractThis paper reviews the effect of natural disasters on human mobility or migration. Although there is an increase of natural disasters and migration recently and more patterns to observe, the relationship remains complex. While some authors find that disasters increase migration, others show that they have only a marginal or no effect or are even negative. Human mobility appears to be an insurance mechanism against environmental shocks and there are different transmission channels which can explain the relationship between natural disasters and migration. Moreover, migrants' remittances help to decrease households' vulnerability to shocks but also dampen their adverse effects. The paper provides a discussion of policy implications and potential future research avenues.
