Beyond the Rain: Why Ghana continues to flood and what must change

By Kofi Agbeko Leh, Development Practitioner | Public Policy Analyst | Researcher in Governance, Sustainable

Development and Resilient Communities

For many Ghanaians, the sound of rain on a rooftop evokes memories of childhood comfort, cooler temperatures, and the promise of a good farming season. Yet for thousands of families across the country, especially during the major rainy season, dark clouds bring a different emotion: fear.

Fear of waking up in the middle of the night to rising waters.

Fear of losing a lifetime of possessions in a matter of hours.

Fear of seeing businesses, schools, roads, and livelihoods washed away.

Every year, flooding affects communities across Ghana. From Alajo and Odawna in Accra to

Aboabo and Anloga Junction in Kumasi, and from Weija to Kasoa, the story repeats itself with painful consistency. Houses are submerged, roads become rivers, businesses close, and families are forced to start over.

As floodwaters recede, one question inevitably returns:

Why do we continue to experience devastating floods year after year despite knowing the causes?

As someone whose work focuses on governance, sustainable development, and public policy, I have increasingly come to view flooding not merely as an environmental challenge, but as a development challenge. Floods often reveal deeper issues within our systems—how we plan our communities, manage our environment, enforce regulations, and prepare for future risks.

The rain may trigger the disaster, but the roots of the disaster often run much deeper.

June 3, 2015: A National Tragedy That Changed Ghana Forever

Few events remain as deeply etched into Ghana’s collective memory as the June 3, 2015 disaster.

On that evening, torrential rainfall overwhelmed large sections of Accra. Water rapidly

accumulated across communities including Circle, Alajo, Adabraka, Kaneshie, and Odawna.

People sought refuge wherever they could find safety.

Some climbed onto rooftops.

Others abandoned vehicles trapped in floodwaters.

Many simply waited and hoped the waters would recede.

Instead, tragedy unfolded. Floodwaters mixed with leaked fuel near a filling station around the Kwame Nkrumah Interchange, triggering a devastating explosion and fire that claimed hundreds of lives. The nation mourned.

For many Ghanaians, June 3 was supposed to be a turning point—a moment that would permanently reshape urban planning, disaster preparedness, and environmental management. Reports were produced, recommendations were made, and interventions were proposed.

Yet more than a decade later, many of the same communities continue to experience annual flooding.

The rain did not change.

The vulnerabilities largely remained.

Alajo: Where Flooding Has Become a Way of Life

In Alajo, flooding is no longer viewed as an unexpected disaster. For many residents, it has become a seasonal reality.

Residents often speak of preparing for rain the same way others prepare for holidays.

Refrigerators are elevated on concrete blocks. Furniture is moved to higher ground. Shop owners carefully monitor weather forecasts, knowing that a single night’s rainfall could wipe out months of investment.

What should be emergency preparedness has become a routine survival strategy.

Situated within the Odaw River basin, Alajo remains highly vulnerable because of its location along a natural drainage corridor. As urban development has intensified and drainage systems have struggled to keep pace, flood risks have persisted.

The people of Alajo have demonstrated remarkable resilience.

But resilience should never be mistaken for a solution.

No community should have to normalize annual flooding.

Odawna and Circle: The Cost of Overburdened Infrastructure

Few locations symbolize Accra’s flood challenge more than Odawna and Circle.

The Odaw River serves as one of the capital’s most important drainage channels. Yet decades of rapid urbanization, waste accumulation, sedimentation, and encroachment have reduced its capacity to effectively carry stormwater.

When heavy rainfall occurs, enormous volumes of water converge in this area.

Vehicles become stranded.

Businesses close.

Commuters are trapped.

Economic activity grinds to a halt.

For traders operating around Circle, flooding is not merely an inconvenience; it represents lost

income, damaged goods, disrupted supply chains, and uncertainty.

Flooding here illustrates a broader reality: infrastructure originally designed for a much

smaller urban population is increasingly being asked to serve a rapidly growing metropolis.

Aboabo and Anloga Junction: Kumasi’s Recurring Flood Story

Flooding is not solely an Accra problem.

In Kumasi, communities such as Aboabo, Anloga Junction, Dichemso, Buokrom, and parts of

Asokwa have repeatedly experienced flood-related disasters.

For many traders, the fear of flooding often rivals concerns about business performance.

A trader who spends years building inventory can lose everything overnight. Families that have gradually improved their living conditions can suddenly find themselves repairing walls, replacing household items, and searching for temporary accommodation.

Children miss school.

Businesses struggle to recover.

Household savings disappear.

These impacts rarely make national headlines, yet they represent some of the most significant hidden costs of flooding.

Weija and Kasoa: Urban Growth Creating New Risks

The rapid growth of peri-urban settlements has introduced new dimensions of flood vulnerability.

Communities around Weija and Kasoa have experienced significant population growth over the past two decades. New housing developments, roads, commercial facilities, and residential estates continue to transform the landscape.

Economic growth is welcome.

However, development that outpaces planning can create new risks.

Areas that once absorbed rainwater through vegetation and open spaces are increasingly covered by concrete and asphalt. Water that previously infiltrated into the soil now flows rapidly across hardened surfaces, increasing runoff volumes and flood intensity.

The consequence is that communities that were not historically flood-prone are increasingly becoming vulnerable.

What My Work Has Taught Me About Flooding

Through my work in governance, development, and public policy, I have learned that disasters rarely occur because of a single event.

They emerge when hazards meet vulnerability.

Heavy rainfall becomes a disaster when drainage systems are inadequate.

Stormwater becomes destructive when wetlands disappear.

Flooding becomes deadly when planning regulations are ignored or poorly enforced.

In many respects, flood disasters are accumulated development failures revealed by a single rainfall event.

The floodwaters merely expose vulnerabilities that have been building for years.

The Real Causes: Looking Beyond the Rain

Poor Waste Management

One of the most visible contributors to flooding remains improper waste disposal.

Plastic waste, discarded packaging materials, and household refuse frequently find their way into drains and waterways. During heavy rains, these materials obstruct water flow and significantly reduce drainage capacity.

Flood prevention therefore begins not only with engineering but also with responsible waste management and environmental stewardship.

Encroachment on Waterways and Wetlands

Nature has its own flood management system.

Wetlands, streams, floodplains, and natural drainage corridors are designed to absorb, store, and convey excess water.

When these ecosystems are filled, occupied, or built upon, water does not disappear. It simply finds alternative pathways—often through homes, roads, schools, and businesses.

Across many parts of Ghana, gradual encroachment on natural water systems has reduced the landscape’s ability to manage rainfall.

Rapid Urbanization Without Matching Infrastructure

Ghana’s urban population continues to grow rapidly.

Unfortunately, infrastructure investments have not always expanded at the same pace.

Drainage systems designed decades ago are now expected to serve populations several times larger than originally anticipated.

The result is predictable: systems become overwhelmed during intense rainfall events.

Climate Change and Extreme Weather

Climate change is no longer a future threat.

Its impacts are increasingly visible across West Africa.

Rainfall events are becoming more intense, more concentrated, and less predictable. Larger volumes of rain can now fall within shorter periods, placing unprecedented pressure on urban infrastructure.

This means flood management strategies must be designed not only for today’s climate but also for tomorrow’s realities.

Flooding Is a Governance Issue Before It Becomes a Disaster Issue

One of the most important lessons Ghana must embrace is that flooding is fundamentally a governance issue before it becomes a disaster management issue.

Flood risks are influenced by decisions regarding:

• Land use planning
• Infrastructure investment
• Environmental protection
• Urban development
• Regulatory enforcement
• Institutional coordination

When planning regulations are inconsistently enforced, vulnerabilities accumulate.

When environmental safeguards are overlooked, vulnerabilities accumulate.

When maintenance of public infrastructure is delayed, vulnerabilities accumulate.

The eventual flood may last only a few hours, but the decisions that created the conditions for disaster may have been years in the making.

The Hidden Economic Cost of Flooding

The true cost of flooding extends far beyond damaged buildings.

Families lose savings.

Businesses lose inventory.

Workers lose income.

Governments divert resources from development projects to emergency response and reconstruction.

Investors become cautious.

Insurance costs increase.

Productivity declines.

For low-income households, a single flood event can reverse years of progress.

For the national economy, recurring floods represent a significant but often underestimated development burden.

Flood prevention is therefore not simply an environmental investment.

It is an economic investment.

What Must Change?

Invest in Climate-Resilient Infrastructure

Drainage systems must be modernized, expanded, and maintained regularly.

Infrastructure planning should account for projected population growth and future climate risks.

Strengthen Enforcement, Not Just Regulations

Ghana possesses many of the laws and planning frameworks required to reduce flood risks.

The challenge often lies in implementation.

Consistent enforcement is essential.

Protect Wetlands as National Assets

Wetlands should be treated as critical infrastructure rather than vacant land awaiting development.

Their ecological value translates directly into flood protection.

Improve Community-Based Waste Management

Flood prevention begins at the community level.

Public education, improved waste collection services, and citizen participation remain indispensable.

Build Stronger Early Warning Systems

Timely information saves lives.

Investments in weather forecasting, risk communication, and emergency preparedness can significantly reduce human casualties.

Promote Integrated Flood Governance

No single institution can solve flooding alone.

Effective flood management requires stronger coordination among government agencies, local authorities, traditional leaders, civil society organizations, researchers, the private sector, and communities.

Conclusion: Beyond Emergency Response

Every flood season, Ghana demonstrates extraordinary resilience.

Communities support one another.

Volunteers assist affected families.

Emergency responders work tirelessly under difficult circumstances.

Yet resilience alone is not enough.

Our national objective should not simply be to become better at recovering from floods.

It should be to reduce the likelihood of floods becoming disasters in the first place.

Ghana possesses the knowledge, expertise, institutions, and human capacity needed to significantly reduce flood risks. What remains is the collective commitment to act consistently before disasters occur rather than after lives, livelihoods, and public resources have already been lost.

The next major storm will come.

The question is whether we will continue to repeat the familiar cycle of destruction and recovery, or whether we will use the lessons from Alajo, Odawna, Aboabo, Weija, Kasoa, and countless other communities to build a safer, more resilient future.

The rain may be inevitable.

But the disaster does not have to be.
