This study examines the links between climate change and migration, showing how environmental stressors drive human mobility. Produced by Cairo University’s Migration Research Unit in partnership with IOM, the study draws on case studies from Bangladesh, Mexico and Morocco, with special emphasis on Egypt as a highly vulnerable lower-middle-income country. It situates climate-induced migration within broader social, economic and political contexts, analysing both rapid- and slow-onset events and their differentiated impacts on vulnerable populations. Offering fresh insights and lessons, this report speaks to policymakers, researchers and practitioners confronting one of today’s most pressing global challenges.
