MULTI-PLATFORM MONITORING OF COASTAL EROSION AT A POCKET BEACH

Abstract

As in many other regions of the world, coastal recession in West and Central Africa is the result of natural factors, anthropogenic factors, or both (Anthony et al., 2016; Luijendijk et al., 2018), and when it occurs, it may continue unless it is firmly addressed. Erosion along Ghana's coastline is endemic as in most of the Gulf of Guinea countries in West Africa. The current challenge is how to document and understand the dimensions of erosion despite limited human and logistical capacity. Regular monitoring of coastal areas is a prerequisite to evade any imminent erosive disaster within the coastal cities (Angnuureng et al., 2022). Data-driven decisions have remained more uncertain because most monitoring platforms are unable to capture events of a certain frequency. The main goal of this work is to test the feasibility of using multiple sources of remote sensing platforms to assess the dynamics of a pocket beach at Elmina in Ghana, as a showcase for local governance.
