Global and National Relevance
-
Global: Coastal erosion is a widespread climate-induced hazard threatening small island states and coastal nations worldwide.
-
National: In Ghana, coastal erosion is most severe along the Eastern and Central coasts, particularly in Keta, Ada, and Cape Coast, where entire settlements, roads, and farmlands have been lost.
Causes and Drivers
-
Natural factors: Strong wave action, sea level rise, storm surges, tidal currents.
-
Human activities: Sand mining, removal of mangroves, construction of ports and sea defense structures altering sediment flow.
-
Climate change: Intensifying rainfall and storms accelerate erosion.
Impacts in Ghana
-
Human settlements: Communities like Keta and Ada Foah have lost houses, schools, and churches to the sea.
-
Infrastructure: Roads, fishing landing sites, and sea defense projects are under threat.
-
Livelihoods: Fishing and salt mining communities face reduced productivity and displacement.
-
Environmental: Loss of wetlands, mangroves, and biodiversity hotspots.
Hotspot Locations
-
Keta and Anloga (Volta Region) – severe loss of land and displacement.
-
Ada Foah (Greater Accra Region) – destruction of settlements and farmland.
-
Cape Coast and Elmina (Central Region) – historical forts and coastal communities threatened.
-
Shama and Axim (Western Region) – fisheries and coastal villages at risk.
Current Situation & Interventions
-
Sea defense projects (Keta, Ada, Sakumono, and Dansoman) have slowed erosion in targeted areas but shifted the problem to nearby coastlines.
-
Resettlement efforts for displaced communities are ongoing but face challenges with livelihoods and cultural attachment to the coast.
-
Policy and Planning: The National Climate Change Policy and Coastal Development Plans emphasize integrated coastal zone management.
Public Safety and Preparedness
-
Awareness creation: Educate coastal residents on early warning signs and risks.
-
Regulation: Enforce bans on sand mining and illegal developments along the coast.
-
Adaptation: Encourage mangrove restoration and community-driven shoreline protection.
-
Emergency Preparedness: NADMO and local assemblies to prepare evacuation and relocation plans for high-risk communities.
