The Morphological Classification and Protection of The Central Coastline: Implications for Coastal Erosion Management in Ghana
The study sought to classify the coastline between Cape Coast and Sekondi and to evaluate the measures put in place to manage and control sea erosion. It involved field observation and community interactions. Satellite and photographic images were used to present the data with the help of Geographic Information System (GIS). It was observed that the central coastline is made of alternating sandy and rocky characteristics. The rocks around Cape Coast were mainly metamorphosed schist, originating from igneous and metamorphic outcrops. Those from Komenda to Sekondi were mostly Sekondi sandstone. In all, it can be said that about 40-45% of the coastline under study that is, between Ekon and Sekondi, is rocky and mainly made up of granite and sandstone. It was also revealed that both hard and soft structures have been used as sea defense mechanisms to manage and protect the shoreline. There is both governmental and community initiatives to ameliorate the dangers of coastal erosion. The paper therefore recommends that human activities that aggravate the natural causes of sea erosion should be stopped. Moreover, any attempt to control sea erosion should be done based on the nature of the coastline and also with the involvement of the local communities to ensure commitment and community ownership.
