Engineers Propose Nature-Based Fix for Accra’s Flood Crisis
Written on
Accra’s flood problem may not be a drainage issue alone. Engineers say decades of urban growth have overwhelmed the city’s natural ability to absorb stormwater, demanding a complete rethink of flood management.
The Ghana Institution of Engineering (GhIE) is advocating a major overhaul of Accra’s flood management strategy, arguing that traditional drainage systems can no longer cope with rapid urbanization and changing rainfall patterns. The institution says recurring floods are being worsened by extensive paving, loss of natural water-retention areas, poor waste management, and fragmented planning systems.
Rather than relying solely on larger drains, GhIE is proposing nature-based solutions such as rain gardens, permeable pavements, green roofs, detention systems, and rainwater harvesting. The recommendations also include stronger land-use enforcement and new runoff-control policies to ensure future developments do not increase flood risks.
If adopted, the strategy could not only reduce flooding but also lower infrastructure costs, improve water quality, and create new opportunities in Ghana’s growing green economy.
