Article
The Ghanaian coast is eroding at a significant rate. A comprehensive understanding of the dynamics of a beach is vital for its management. Two decades of shoreline and a short-term sediment volume change data on the Apam Beach were analysed from freely available satellite and drone images, respectively. After assessing its long-term shoreline chang...

Regular monitoring of coastal areas is a prerequisite to evade any imminent erosive disaster. However, data-driven decisions become more uncertain when a monitoring platform is unable to capture events of a certain frequency. Erosion along Ghana’s coastline is endemic as in most of the Gulf of Guinea countries in West Africa. The current challenge...

Abstract: The rapid urbanization, industrialization, agricultural activities, and increasing trend of some natural hazards, such as climate change, particularly in coastal areas, necessitate the continual assessment of critical but fragile ecosystems like that of the Keta Lagoon Complex Ramsar Site (KLCRS). This productive ecosystem in Ghana faces...
Article
Erosion is a major challenge facing coastal regions globally and it is projected to increase on regional to global scale as sea levels continue to rise. Deltas, which are important ecosystems, are particularly vulnerable due to their low-lying nature, subsidence, reduction in sediment supply, population increase and exposure to increasing frequency...

Beaches are characterized by complex spatial and temporal patterns of erosion and accretion subjected to significant wave and tide influence. The objective of this study is to estimate the evolution of hydromorphodynamic conditions on the shoreline of Grand Popo Beach observed from two adjacent video camera setups. We have analyzed the impact of th...
Article
Coastal erosion has become an issue globally. As the sea level continues to rise due to global warming, projections are that erosion would increase. To address the issue sustainably, relevant scientific information such as sediment transport and shoreline dynamics is required at local scales. Over the years, erosion at the eastern coast of Ghana ha...

The West African coast is vulnerable to natural hazards and human interventions. Although various measures have been taken at different scales, mostly at the local level, there is a need to improve management at the regional level. We examine these actions and possible solutions from different perspectives and provide conclusions and recommendation...
Article
Full-text available
Beaches are economically important natural coastal resources. They add beauty to the coast and provide habitats for many organisms as well as services to people. The focus of this paper was to investigate whether beach users were aware of the key factors that affect the quality of the Elmina beach. Specifically, the physical, social and economic pr...
Article
Full-text available
Video camera systems have been used over nearly three decades to monitor coastal dynamics. They facilitate a high-frequency analysis of spatiotemporal shoreline mobility. Video camera usage to measure beach intertidal profile evolution has not been standardized globally and the capacity to obtain accurate results requires authentication using vario...

The coast of Cameroon is located at the bottom of the Gulf of Guinea with varied nearshore environments and oceanic forcing influenced by the presence of several islands. It is also the area of important river flows. Here, the global evolution of the Cameroonian coastline and hydrodynamic between 1986 and 2015 is investigated using satellite images...

This paper presents the description of a 2-dimensional shoreline and 3-dimensional shoreline behaviour around a 'storm free' microtidal beach from a 3-year video observation using empirical orthogonal function (EOF) analysis. The EOF method is applied successfully to delineate 2D and 3D developments that show the beach evolution influenced by the a...

The morphology of sandy beaches is highly dynamic. They are influenced by the geology of the coastal area and external hydrodynamic forcing. On long timescales (years to decades), it is more efficient and convenient to monitor beach evolution through remote sensing technics rather than through direct field measurements. Erosion is a major problem a...

Project
WACA-VAR project, by the IRD Team and its African partners, strategically builds a long-term coastal adaptability and resilience along the West African coast. It intends to carry out an in-depth, multidimensional assessment of coastal vulnerability and solutions along the WA coast with the intent of providing critical knowledge and pathways to more WA coastal area's resilient futures. Our goal is to develop studies that would lead to the formulation and implementation of innovative and sustainable plans and policies for the management of the WA coastal areas and establish value-added relative to the World Bank WACA project objectives.
Project
The overarching goal of this project is to establish quantifiable, easy-to-employ but ecologically reasonable metrics for identifying the combined impact of climate change and human-induced factors on coastal ecosystems. The specific objectives are: I. To investigate the relationship between global change factors such as sea level rise, water temperature, rainfall and pollution, and the extent to which their interactions may set the levels of new biomass production in coastal areas. II. To train graduates to develop a simulation model to predict the responses of ecological communities and ecosystem processes to the combined effects of natural forces, climate change and anthropogenically induced stressors. III. To provide real time data on nearshore physical processes to support understanding on sediment dynamics and coastal resilience
Project
To explore the use of technology to provide the much needed enhancements in our knowledge of coastal processes and modeling capabilities in West Africa
