“…Sadio et al [62] informed us that the average erosion rate for the entire coast along the Saloum River mouth between Diakhanor and Sangomar, Senegal, remains at −3.56 m/year. Komolafe et al [60] again revealed that approximately 40 km of the shoreline of Ilaje-Ondo State, Nigeria, was accreting with an average of 1.08 m/year and an average erosion rate of −1.40 m/year. Foli et al [100] also said that the rate of erosion ranged between 1 and 30 m/year for the period 2015-2018 in Ghana, Guinea, Guinea Bissau, Liberia, Nigeria, and Senegal.…”

“…As the number of original research studies on shoreline change and erosion of coasts and beaches increases across coastal regions of the world, the number of literature reviews that portray the state-of-the-art research stance and policy direction on the subject has also increased (e.g., [10,35,[46][47][48][49][50][51][52][53][54]). While the number of literature review studies on the subject increases in many regions of the world, the research progress and policy stance on the subject in question remain limited in the West African region, although original research exists (e.g., [13,[55][56][57][58][59][60][61][62][63]). While the original research keeps increasing in the region, it is equally important to understand the state-of-the-art stance and progress on the subject in the region and the policy directions recommended.…”

Shoreline Change and Coastal Erosion in West Africa: A Systematic Review of Research Progress and Policy Recommendation

Shoreline change and coastal erosion resulting from natural events such as sea level rise and negative anthropogenic activities continue to be problems in many of the world’s coastal regions. Many coastal socio-ecological systems have become vulnerable as a result, especially in developing countries with less adaptive capacity. We utilized the systematic method to understand the research progress and policy recommendations on shoreline change and coastal erosion in West Africa. A total of 113 documents were retrieved from Scopus and the Web of Sciences databases, and 43 documents were eligible following established criteria. It was revealed that research on shoreline change and coastal erosion has progressed substantially since 1998, with most research studies originating from the Ghanaian territory. Again, most of the shoreline change and erosion problems in West Africa result from natural events such as sea level rise. However, there was evidence of anthropogenic influences such as sand mining, dam construction, and human encroachment causing shoreline change and erosion in the region. Research in the region has also progressed in terms of methodological approaches. Since 2004, researchers have utilized remote sensing and GIS techniques to source and analyze shoreline change and erosion. However, a combination of remote sensing and field observation approaches is required to clearly depict the erosion problems and aid policy direction. The overall call to action regarding policy recommendations revolves around improving coastal adaptation measures and the resilience of communities, instituting proper coastal zone management plans, and improving shoreline change and coastal erosion research. To protect lives and property, policymakers in the region need to set up good coastal zone management plans, strengthen adaptation measures, and make coastal communities more resistant to possible risks.

“…Adediji and Ezenwa [38] compared satellite images from 1986 and 2013 with a topographic map from 1969, while Dada et al [39] examined coastline changes using satellite images from 1987 to 2017 in the Ilaje region. Additionally, Badru et al [40] and Komolafe et al [41] investigated coastal changes using statistical techniques such as end point rate (EPR) and Net Shoreline Movement (NSM) over different time periods. Daramola et al [42] conducted a study on changes in coastal positions employing the linear regression rate (LRR), endpoint rate (EPR), and root mean square error (RMSE) methods.…”

Erosion presents a significant challenge to coastlines worldwide, and the Ilaje area in Nigeria’s Niger Delta is no different. Aggressive flooding along this shoreline has led to property damage, economic disruption, and a looming threat to the survival of riverine communities in the region. This study presents a comprehensive analysis of spatial and temporal changes in the Ilaje coastal area of Ondo state from 1986 to 2020. The analysis utilized the SCE, EPR, and LRR methods to examine shoreline changes. Additionally, spatial digitization was performed for Ayetoro, a highly susceptible coastal community, spanning from 2008 to 2023. The results indicate that approximately 86% of the coastline experienced erosion, while the remaining 14% underwent accretion. Notably, the western and central sections of the coastline emerged as the areas most vulnerable to erosion. Ayetoro, situated centrally, faces dire circumstances. The interplay of natural geomorphic processes and human activities played a role in driving these changes. Beyond the immediate physical alterations, erosion has reverberated through the local ecosystems, livelihoods, and infrastructure, posing risks to numerous communities. This study emphasizes the need for urgent actions through integrated coastal zone management (ICZM) strategies to promote coastal stability in the region. The results of the study further provide valuable insights into the need for coastal managers and planners to regularly assess the state of the coastline and proactively proffer suitable solutions to reduce rampant coastal degradation.
