Every rainy season, the same cycle repeats itself. Communities are submerged, families lose their homes, businesses suffer huge losses, roads become impassable, and the government spends millions of Ghana cedis on emergency relief. Yet, once the floodwaters recede, national attention fades until the next disaster.
Ghana cannot continue to respond to flooding as an emergency. It must be managed as a predictable national risk through science, technology and evidence-based planning. The Council for Scientific and Industrial Research (CSIR), through its Research Staff Association (RSA), has proposed an actionable flood mitigation strategy that combines immediate interventions with medium- and long-term investments to reduce flood disasters across the country significantly.
Short-term actions: Save lives before the next rains The priority should be reducing the immediate risk to lives and property. Routine environmental sanitation inspections must be intensified to ensure drains remain free from solid waste. Flood-prone communities should be scientifically mapped by CSIR to guide planning and emergency response.
Metropolitan, Municipal and District Assemblies must desilt drains before the peak rainy season while existing sanitation and water management laws are strictly enforced. Technology should also become central to disaster preparedness. Ghana needs an integrated flood early warning system that delivers timely alerts through SMS, radio, social media and other communication platforms.
At the same time, portable CSIR-developed water purification systems should be deployed to flood-affected communities to provide safe drinking water and prevent outbreaks of water-borne diseases. Medium-term investments: Address the root causes Flooding cannot be solved by clearing drains alone. Illegal mining (galamsey), uncontrolled deforestation and degradation of watersheds have significantly reduced the landscape’s ability to absorb rainfall.
Halting these destructive activities must become a national priority. Government should also restore degraded wetlands and watersheds, construct recharge ponds that allow stormwater to infiltrate naturally into aquifers, and deploy smart sensors to continuously monitor surface water and groundwater levels. Such investments would not only reduce flood peaks but also improve groundwater resources and strengthen water security during the…
