This study tests the influence of environmental changes on migration in Burkina Faso. It describes individual migratory pathways in the 1960-1999 period in Burkina Faso, using environmental typologies of origins and destinations based on rainfall variations and land degradation. The study links data from a national longitudinal (retrospective) survey with fine resolution rainfall data and land degradation data. Results suggest that environmental factors influence, but in different ways, both the probability to out-migrate and the selection of a destination once the migration decision has been made. Migration seems to be more influenced by a slow-acting process such as land degradation than by episodic events such as droughts.
