Journal of Coastal Conservation, 17(1), 75-84. doi:10.1007/s11852-012-0219-yhttp://hdl.handle.net/10625/52786The Ada peninsular in Ghana has suffered rapid coastal erosion and inundation for over half a century, accompanied by loss of property and livelihoods, economic stagnation and salt water intrusion. Government intervened to respond to these threats by implementing a sea defence project. A preliminary assessment indicates the project will deal with some urgent needs of property loss reduction and invigorate livelihood and economic opportunities. However, it will have minimal beneficial impacts on groundwater salinization, and may actually intensify salinity of surface water in the Volta River and adjoining water points by shifting salinity intrusion further upstream to affect hitherto salinity-free areas. The spatial reach of the salinity shift is uncertain. The potential for further sea level rise will aggravate and accentuate the region’s water scarcity dilemma if a coherent water management strategy is not sort sooner. The project demonstrates the limitations of employing static, narrow objectively designed sea defence project as a response to coastal erosion and inundation, because it lacks the capacity to deal with dynamism, complexity and multi-dimensional impacts associated with climate change related sea level rise.application/pdfenCOASTAL INUNDATIONSALT WATER INTRUSIONCLIMATE CHANGESEA LEVEL RISESEA DEFENCEGHANAGHANA--ADA AREASALINIZATIONCOASTAL EROSIONWATER SHORTAGECOMPLEXITYDRINKING WATERCOASTAL WATERSEROSIONDAMSSEA WALLWATER QUALITYECOSYSTEMSHARBOUR AND COASTAL ENGINEERINGJournal Article (peer-reviewed)
