Climate Change-Induced Migration and Its Implication for Sustainable Development: Case of Lake Chad and Lagos Megacity Sub-Regions, Nigeria’’

Tai K. Oyekan, UNICAF UNIVERSITY, ZAMBIA

A twin challenge of climate change resulting in resource depletion and contributing indirectly to insurgency induced a forced migration from an impoverished region. In Lake Chad basin, populations are trapped between consequences of climate change and insecurity. The negative impact of environmental change is epitomised by the receding lake and compounded by insurgency of Boko Haram, generating IDPs and precipitating forced migration towards socio-economically more prosperous southern regions. The conceptual framework is situated within the Push and Pull theory of migration and the division of its factors in Lee’s laws. Data analysis revealed Lagos as not only a naturally attractive destination for these migrants but confirmed that the migrants were both internal and international. The implication is the increased pressure on the resources of the receiving city, depletion of human resources, conflict over depleted resource and conscription into insurgency in the originating region.
