Abstract
Most coastlines in the world are under the threat of erosion. As such many developed nations
16 have instituted long-term measures to control the rate of change. However, along most
17 developing nation coastlines, little attention is given to coastal erosion management. Ghana
18 like most developing countries has little commitment to ensure the effective monitoring and
19 management of coastal erosion. Consequently, many of its coastal communities and
20 important historical monuments are now under severe risk to sea erosion. This study focuses
21 on the shoreline evolution that occurred along the Elmina, Cape Coast and Moree coast of
22 Ghana during a thirty-eight year period using available datasets that allowed the authors to
23 discern what happened between 1974 and 2005, and in the most recent years, between 2005
24 and 2012. Shoreline data from 1974, 2005 and 2012 were incorporated in Geographic
25 Information System (GIS) using ArcGIS for analysis. The net shoreline movement and end
26 point rate statistics were generated by ArcGIS together with Digital Shoreline Analysis
27 System software extension. The study identified that in all the three epochs considered, there
28 were a general erosion trend in the shoreline changes. This study has provided valuable and
29 comprehensive baseline information on the state of the coastline in the Elmina, Cape Coast
30 and Moree area which can serve as a guide for coastal engineers, coastal managers and policy
31 makers in Ghana to manage the risk.
