CLIMATE-INDUCED MIGRATION IN COASTAL AREAS OF NIGERIA AND ITS ECONOMIC EFFECTS ON COASTAL ECOSYSTEM LIVELIHOODS
Résumé
Migration is an aged long phenomenon, which has been increasingly drawing attention from several disciplines, including economics. The effects of climate change on migration have also been increasingly gaining attention among researchers as well as those in charge of policy design and implementation in the past two decades. This paper presents a review on the effects of climate change on Migration flows in coastal areas of Nigeria. More specifically, the paper identifies coastal vulnerabilities in the face of climate change and the impact of climate change on future coastal livelihood opportunities. It also identifies the differences in age, gender and other patterns in the migratory movements. The paper notes that further rising sea level in future could make urban-urban migration dominate the prevailing rural-urban mobility in Nigeria, if measures are not taken to boost coastal adaptation and this will put more pressure on urban infrastructure and assets. The paper therefore, recommends the need for investment in coastal adaptation, since the future benefits from adaptation (net benefits) outweighs the cost of non- adaptation.
