Decades of recurring floods in Greater Accra have claimed lives, destroyed property, and disrupted livelihoods. Researchers now warn that approximately 20% of houses built on waterways may need demolition to restore natural water flow, as human activities have severely disrupted Accra’s drainage systems. Studies confirm that poor and uncoordinated land use planning—not climate change—is the root cause of flooding in Ghana’s capital.
Human activities continue to worsen the crisis. About 80% of drain blockages in Accra stem from improperly disposed of plastic waste, as citizens litter and dump refuse into gutters. Encroachment on wetlands for housing and commercial infrastructure has altered natural water flow, while widespread deforestation has reduced the soil’s capacity to absorb excess rainwater. Similar flooding patterns are emerging in other Ghanaian cities like Kumasi and Takoradi due to unplanned urbanisation and illegal dumping.
Rather than resorting solely to large-scale demolition, experts propose four alternative solutions:
Equipping physical planning agencies with the authority and resources to enforce existing land use laws will prevent construction on wetlands and waterways.
Community-based waste collection, capping of open dumps, and public education campaigns can drastically reduce plastic waste entering drains—addressing the root of 80% of blockages.
Systematic dredging before rainy seasons, combined with sustained maintenance to prevent re-siltation, ensures waterways remain functional.
Reforestation projects, creation of urban green spaces, and restoration of natural wetlands will enhance water absorption and reduce runoff.
Close to $3.2 billion in economic assets in Greater Accra remain at risk of flooding—a figure that could quadruple by 2050 without intervention. Addressing Accra’s flood crisis demands coordinated action, civic discipline, and investment in sustainable urban planning rather than reactive demolition alone.
