【 摘 要 】

The phenomenon of ocean surges and other morphological processes along theLagos coastline have generated serious public concern on the vulnerability of infrastructuresand coastal services along the entire stretch of the Barrier-Lagoon coastline of Lagos State.This study examines Badagry coastal environment inundations that arise from sea level rise.The study uses an iterative GIS-based simulation that mapped area inundated based onIntergovernmental Panel on Climate Change - Special Report on Emissions Scenarios (IPCC–SRES) classification (A1, A1T, B2, A1B and A2) and Locally OrientedEconomic Development Scenarios (LOEDS). The results of IPCC-SRES scenario analysisshow that area inundated at the high emission and worse case sea level rise is less than 0.13%of the study area while the LOEDS inundation area starts having significant impacts as from 4meter rise in sea level. Since it is only environmental catastrophism and anthropogenicactivities that can attain such serious dimension at local, regional and global scales in sealevel, it is recommended that coastal protection infrastructures should be integrated in anymajor developmental activities.
