The paper attempts to understand the links between city development in Lagos, with
particular reference to growth of slums, and risks from climate change. The impacts and
vulnerabilities of residents of selected poor urban communities along the coast of Lagos to the
increasing risks of floods arising from climate change are assessed. An impact and vulnerability
assessment within an integrated assessment framework that includes both natural and human
sub-systems interactions is adopted for the study. Quantitative and qualitative methods including
the analysis of acquired data sets, administration of household questionnaires, interviews with
key informants and focus group discussions are employed to generate primary data.
