Abstract
In recent years, the Kribi coast in Cameroon has experienced significant coastal erosion, resulting in the submersion of land parcels, including those with land titles. This study aims to create a spatial data infrastructure (IDoGek) to monitor and manage coastal changes from 2015 to 2023, enabling better planning and sustainable growth in the region. Using DSAS (ArcGIS plug-in), historical data and remote sensing analyses revealed a loss of over 7 hectares of land, with erosion rates averaging 1.1 meters per year. By 2034, up to 11 hectares could be lost without intervention, as some areas may retreat by 10.97 meters. This approach maps land use changes, tracks coastline positions, and assesses the kinetics of coastal erosion. The results emphasize the need for high-resolution imagery, offshore tide gauges, and integration of remote sensing with in-situ data to enhance monitoring and develop effective solutions for the sustainable management of Kribi's vulnerable coastal zones.
