Environmental and climatic factors not only account for migration to Morocco from sub-Saharan Africa, but also for movements out of and within the country, especially to the major coastal cities. With the severe impacts of climate change expected to rise in intensity in the coming decades, sudden-onset events, such as floods and storms, as well as slow-onset processes, such as droughts and desertification, will further intensify these movements.
