ABSTRACT
This chapter presents coastal interventions that have been used around the world to reduce the effects of coastal hazards. It introduces the study area, and its characteristics. The chapter discusses the available data used for this study. The west coast of Africa is undergoing rapid infrastructural development, tourism, fishery, agriculture and urban growth. These population pressure and exploitation of natural resources have caused coastal environmental degradation. All the morphological changes occurring along the Lagos coast are exacerbated by rising sea levels and land subsidence from lack of sediments and groundwater extraction. The geology of Lagos shows that it is made of Quaternary deposits which are relatively young sediments that are susceptible to compaction. The Niger delta region is a low lying area consisting of several tributaries of the Niger and other rivers and ending at the edge of the Atlantic Ocean.
