Subsistence farmers in Sahelian Africa are highly vulnerable to the rainfall and temperature effects associated with climate change. As a response to climate variability and insecurity, permanent or temporary out-migration can provide a strategy to manage climate related risks. While climate-migration literature among rural farming communities is growing, major questions remain about the climate processes that drive individual- or family-level migration decisions. To examine the climate variability as a factor of out-migration with attention to individual-level variability we examine individual- and community-level responses using highly detailed, full migration histories of 3,150 individuals in two villages in Mali with fine-scale rainfall and temperature data. In an effort to advance scientific understanding of the complexities of migration we focus our attention on a variety of different features of each potential migrant – including the migration histories of each individual. The data are adequately detailed to support analysis investigating how within season climate variability or heatwaves, for example, impact individual out-migration with attention to different out-migration experiences.
