Abstract
Migration is one measure that individuals can take to adjust to the adverse impacts of increasingly extreme weather that can arise from climate change. Using novel geo-referenced high-frequency data, we investigate the impact of soil moisture anomalies on migration within West Africa and towards Europe. We estimate that a standard deviation decrease in soil moisture leads to a 2-percentage point drop in the probability of international migration, equivalent to a 25 percent decrease in the number of international migrants. This effect is concentrated during the months that immediately follow the crop-growing season among areas in the middle of the income distribution. The findings suggest that weather anomalies negatively affect agricultural production, leading to liquidity constraints that prevent people from moving internationally.
期刊介绍:
The Journal of Environmental Economics and Management publishes theoretical and empirical papers devoted to specific natural resources and environmental issues. For consideration, papers should (1) contain a substantial element embodying the linkage between economic systems and environmental and natural resources systems or (2) be of substantial importance in understanding the management and/or social control of the economy in its relations with the natural environment. Although the general orientation of the journal is toward economics, interdisciplinary papers by researchers in other fields of interest to resource and environmental economists will be welcomed.
