Lagos, like most other coastal cities is associated with many of the consequences of such ecological relationships, which include physical alterations and destruction of coastal habitats, flooding, erosion, pollution and continued threats from rising sea levels. Thus, in order to ensure sustainable coastal area management, techniques are required that provide cost effective means for mapping and monitoring landcover change and impacts. In this study, the aim was to evaluate the attendant socio-economic and environmental implications of the changing pattern of landcover change associated with the Lagos coastal zone. The observed (1986-2002) and predicted (2002-2027) rapid and continuing landcover change in the Lagos coastal area have multifarious implications on the residents and inhabitants of the area and on the entire Lagos residents in general; which is a consequence of the multiple impacts (positive and negative) that affect the ability of biological systems to support human needs. Some of the positive impacts of landuse/cover change include the continued increase in food and fibre production, resource use efficiency, wealth, livelihood security, welfare and human well-being. However, the undesirable and negative impacts of landcover change include massive alterations o f biogeochemical cycles (e.g. nitrogen, carbon and water), ecosystem processes, earth-atmosphere interactions, loss of biodiversity and soil degradation at different spatial and temporal scales. For instance, the expansion of the developed landcover into the swamp landcover type would have destructive consequence on the ecological biodiversity of the area and an attendant reduction in the livelihood of those that depend on these vegetal resources.
