In Ghana, there has been considerable coastal erosion, dating from the beginning of this century. During the period from. West African coast are expected to rise faster than the global average (UEMOA ). In addition, changing KNOWLEDGE SHEET 6 The Effects of Climate Change on Coastal Erosion in West Africa KEY CLIMATE IMPACTS ON COASTAL EROSION • Rising sea levels, intensifying storm surge, and extreme precipitation are likely to accentuate. Ibe, A.C. and Quelennec, R.E. () Coastal Erosion Inventory and Control Methodology in the West and Central Africa Region. Regional Seas Reports and Studies, UNEP, Nairobi, p. has been cited by the following article: TITLE: Physical Forcing Induced Coastal Vulnerability along the Gulf of Guinea.   In West Africa, coastal erosion remains a problem for the socio-economic development of the coastal zone. Case studies in Senegal and Benin indicate a strong intensification of coastal erosion, in relation to human influence, as shown by the analysis of .

Coastal erosion is the net landward retreat of the shoreline, where the shoreline is represented by a datum such as mean high water spring or a mapped feature such as a cliff, beach or road (Figure 1).The landward retreat is persistent through time as distinct from shorter term (e.g., weeks, months) fluctuations in the position of the shoreline associated with storm erosion and recovery. Coastal erosion major threat to West Africa (cc) Annabel Symington. Fish Market, Gambia. Coastal activities such as fishing, tourism and commerce are important to the economy in Northwest Africa. Coastal erosion is a major problem for Africa. In northwest Africa, the coasts are economically important since a large part of the gross domestic.   The coastal areas of West Africa is home to 31% of the West African population and produces 56% of the sub region’s GDP. However, today, countries are facing increasing risks of coastal erosion, flooding, salinization of land and coastal waters, as well as depletion of fish stocks, all manifestations that threaten their people and their economic livelihood. West Africa provides the strongest example of intraregional migration flows in sub-Saharan Africa, with 70 per cent of migratory movements mainly linked to employment taking place within the sub-region. (b) In recent years, irregular migration from sub-Saharan Africa towards Europe, and between West and Central Africa, has substantially increased.

The coastal area of West Africa is home to 31% of the West African population and produces 56% of the sub-region’s GDP. However, today countries are facing increasing risks of coastal erosion, flooding, salinisation of land and coastal waters, as well as depletion of fish stocks- all manifestations that threaten their people and their economic livelihood. Coastal Erosion in West Africa and Adaptation Planning. The West African coast mainly consists of a narrow low-lying coastal strip, over a distance of several thousand kilometers. This coastal strip is protected from the sea by a sandy barrier. Large cities have developed in the past decades in this low-lying back-barrier strip, such as Abidjan. Coastal Erosion is usually the result of a combination of factors both natural and human induced operating on different scales. Erosion is defined as the encroachment of land by the sea after average over a period which is sufficiently long to eliminate the impacts of weather, storm events and local sediment dynamics (such as Sand. Surprisingly, this part of the coastal area in West Lomé experiences the opposite phenomenon to erosion, known as costal accretion, which is the process of sediment accumulation in the coastal zone. We wondered if we could put in place a mechanism of sand transportation from west to east, thus helping the coastal zone east of Lomé begin a.
