West and Central Africa — Within and Beyond Borders: Tracking Displacement and Human Mobility in the Lake Chad Basin (March 2019)

The four countries of the Lake Chad Basin (Cameroon, Chad, Niger and Nigeria) are currently affected by a protracted crisis resulting from a complex interaction of factors, including conflict with Non-State Armed Groups, poverty, underdevelopment and a changing climate. The crisis started in North-eastern Nigeria in 2009 and spread to other countries of the Basin in 2014, generating substantial displacements of population and causing grave humanitarian concerns. This report, which primarily rests on data collected through IOM's Displacement Tracking Matrix (DTM), presents the evolution of the numbers, locations, characteristics, and profiles of displaced populations between 2016 and 2018.
