The Government of Ghana has launched a GHS 1 billion coastal protection project to build sea defense walls and protect coastal communities from erosion and flooding.
Project scope:
- 50km of sea defense walls
- 5 major coastal towns protected
- Beach nourishment (sand replenishment)
- Mangrove restoration
- Early warning systems
Locations:
- Keta and Anloga (Volta Region)
- Ada (Greater Accra)
- Winneba and Elmina (Central Region)
- Sekondi-Takoradi (Western Region)
Problem:
- Ghana loses 2 meters of coastline annually
- 80% of coastline is eroding
- 1,500 homes lost to sea in past decade
- Flooding affects 50,000 people annually
- Economic losses: GHS 200 million yearly
Protection measures:
- Revetments (rock walls)
- Groynes (barriers to trap sand)
- Breakwaters (offshore barriers)
- Beach nourishment (adding sand)
- Mangrove planting (natural barriers)
Project timeline:
- Phase 1: 2 years (construction)
- Phase 2: 3 years (monitoring)
- Maintenance: Ongoing
Funding:
- GHS 500 million from government
- $100 million from World Bank
- $50 million from African Development Bank
- $50 million from Adaptation Fund
Benefits:
- Protection of 100,000 people
- Safeguarding infrastructure (roads, buildings)
- Preserving tourism beaches
- Protecting fishing communities
- Climate change adaptation
The project aligns with Ghana's National Climate Change Adaptation Strategy and contributes to the country's commitments under the Paris Agreement.
Environmental considerations include ensuring sea defenses don't simply shift erosion to other areas, and maintaining natural beach processes where possible.
