Abstract

Within the last decades, there has been an extreme occurrence of natural disasters, especially in urban settlements. Due to this, there have been efforts to advance human understanding of social sources of vulnerability to these disasters in an attempt to reduce the high social and material costs. This study therefore explored social sources of vulnerability to natural disaster with focus on floods in informal settlements of Lagos. Lagos represents one of the cities with the fastest growing urban agglomerations in the world. About half of its population lives in informal settlements thereby exacerbating a high degree of vulnerability especially among slum dwellers. This study is based on a comprehensive household survey and key informants interviews as well as on focus group discussions. It documents the scale and frequency of flooding in informal settlements and the impacts as well as the household and community coping and adaptation mechanisms. It also explores the institutional responses and adaptations measures against the prevailing flood situation. The study also examines how factors such as lack of infrastructure, poor socio-economic and locational disadvantages contributes to the vulnerability of slum dwellers to floods. The coping and adaptation mechanisms employed in this study depended upon the diversity and accessibility of the available options, economic affordability of the households and level of social networking. From this study, social capital plays a leading role in galvanizing mutual help among neighbours and different networks. Based on the exposures and management capacities identified in this study, recommendations were also made on how to enhance capacities to reduce flood vulnerability in Lagos informal settlements
