Flood Disaster In Nigeria: Predictable Tragedy

Each year, Nigeria is struck by a disaster that has become so routine it barely shocks the national conscience anymore: devastating floods that displace thousands, destroy livelihoods, and cost the country billions in damages. From Lagos to Lokoja, Borno to Bayelsa, the story is the same—swollen rivers, submerged homes, lost farmland.
Children drop out of school as their homes or schools are flooded. Health crises follow, as stagnant water breeds Cholera and other waterborne diseases. Women and children bear disproportionate burdens, from increased caregiving duties to heightened vulnerability in overcrowded displacement camps.
Just last week, the country woke up to another flood disaster. Mokwa, a commercial hub in Niger State was swept away. About 200 lives were lost, 3,000 people were displaced, bridges washed away, families left heart broken.
The painful thing is that the meteorological agencies, the Nigeria Hydrological Services Agency (NIHSA) and Nigerian Meteorological Agency (NiMet) usually issue annual warnings about impending floods but little or nothing will be done by both the authorities and the citizens to avert the disaster until it happens and everybody starts running helter skelter. At a press conference in Abuja on Tuesday, June 3, the Minister of Water Resources and Sanitation, Joseph Utsev, clearly stated that flood warnings were given but they were not adhered to.
Speaking against the speculations that Mokwa flood was caused by the release of water from Kainji and Jebba Dams, he said, “Nigerians would recall that the Federal Ministry of Water Resources and Sanitation through the Nigeria Hydrological Services Agency in the 2025 Annual Flood Outlook on the 10th of April, 2025 predicted flooding in 19 LGAs of Niger State including Mokwa LGA.”
He also referred to the report of 2025 AFO, which indicated that 1,249 communities in 176 Local Government Areas in 33 States and the FCT fall within the High Flood Risk Areas, while 2,187 communities in 293 LGAs in 31 States, including the Federal Capital Territory, fall within the Moderate Flood Risk Areas.
Indeed, the floods in Nigeria are no longer unpredictable phenomena. Reports have it that in 2022, for example, over 600 lives were lost, 1.4 million people displaced, and over 200,000 homes damaged.
Crop-lands were washed away, leading to spikes in food prices and food insecurity. Infrastructure—already fragile—was further crippled. Subsequent years had similar reports. And yet, each year, State governments and citizens alike act surprised when the waters rise.
The causes of these floods are not mysterious. Climate change plays a role, with increasingly intense rainfall and rising sea levels. However, much of the devastation has been traced to human failings: poorly planned urban development, inadequate drainage systems, deforestation, and the mismanagement of river basins and dams.
For instance, the release of water from Cameroon’s Lagdo Dam annually inundates many States across the country, especially when the Dasin Hausa Dam, meant to contain the excess flow, remains incomplete decades after it was conceptualised. Similarly, urban expansion in many cities of the country often encroaches on natural floodplains and wetlands, replacing them with concrete that prevents water absorption and channels run-off into homes and roads.
Experts have claimed that at the heart of the flood disaster in the nation lies a deeper governance problem. Environmental policy is fragmented, implementation is weak, and coordination between federal, state, and local governments is almost non-existent. Flood response is often reactive—focused on rescue and relief—rather than preventive. Agencies like the National Emergency Management Agency (NEMA) and State Emergency Management Agencies (SEMAs) are underfunded and overwhelmed. There is no better truth.
How many government agencies whose job is to prevent floods and other disasters do their jobs? Just like past floods in Nigeria, Mokwa flood has been largely attributed to unregulated buildings and construction activities, poor drainage infrastructure and the likes. And the question is, whose responsibility was it to ensure that these illegal buildings were not erected in the first place? Whose duty is it to ensure that refuse is disposed of properly and that defaulters are punished?
Of course, citizens are not to be exonerated from the blame. Many Nigerians find it difficult to obey rules. Many care less about the environment and they will be the first to cry woes when a disaster occurs. But the point remains that if the regulatory authorities do not wake up to their duties of ensuring that people comply with building codes and urban development guidelines, if they would rather collect money from developers and look the other way when water channels are covered with buildings, then, the floods so far seen might just be a child’s play.
It is high time the governments at all tiers and across all levels stopped seeing floods as seasonal inconveniences rather than existential threats. These authorities are quick to make promises in the aftermath of a flood, but once the waters recede, so does the urgency. Reports are written, funds are pledged, but structural action is rare. The cycle continues: warnings, inaction, disaster, aid appeals, and then silence—until the next year. How can this help the situation?
There is an urgent need for the completion of the Dasin Hausa Dam project in Adamawa State. Experts say that this dam, if functional, would serve as a buffer for the Lagdo Dam releases from Cameroon. The same goes with the need for rehabilitation and expansion of the country’s drainage systems, especially in urban centres. Most existing systems are outdated, clogged, or simply inadequate for today’s volume of rainfall.
Building codes and urban development guidelines must be enforced without compromise. State governments must stop the unchecked development on floodplains and demolish illegal structures that obstruct natural drainage. New developments must include adequate drainage systems, and environmental impact assessments must be mandatory and rigorously enforced.
Government should carry out resettlement programmes for people living in high-risk zones. It is not enough to announce that people living along river banks and flood prone areas should move to higher lands. Are provisions made for them to move and to settle on higher lands?
Also, early warning systems must go beyond press releases and scientific bulletins. They must translate into community-level awareness and preparedness. NEMA and SEMAs should partner with local governments, traditional institutions, and civil society to educate the public on flood risks and evacuation plans.
Community-based disaster response teams can be trained and equipped to act swiftly when floods occur. More importantly, simulations and drills should be conducted periodically, not just after disasters strike.
It is also important that the government, both state and federal, collaborate with the private sector to introduce subsidised flood insurance scheme, especially for farmers and small business owners who bear the brunt of flood damages.
Climate change is no longer an abstract threat; it is a daily reality. Federal and state governments must integrate climate resilience into all development policies. Ministries of Environment, Works, Water Resources, and Agriculture must collaborate to build climate-smart infrastructure.
This also includes reforestation projects, sustainable agriculture practices, and policies to reduce carbon emissions. Nigeria’s national climate adaptation plan must be updated and fully implemented, with budgetary allocations that reflect the seriousness of the problem.
Transparency in the use of emergency funds and infrastructure budgets is essential. Anti-corruption agencies should investigate diversion of funds meant for disaster preparedness and flood mitigation.
Nigeria’s flood disaster is now a national emergency that requires urgent, collective, and sustained action. We can no longer afford the complacency that treats annual floods as inevitable. The science is clear, the patterns are consistent, and the solutions are known. What is missing is the will to act.
A flood-resilient Nigeria is possible. It begins with planning, continues with investment, and is sustained by accountability. We must break the cycle of annual disaster and move toward a future where the rainy season is a blessing, not a curse.
President Bola Tinubu must be commended for approving the release of ?2 billion, 20 trucks of rice for victims. That will go a long way in helping them if they are not diverted by those in the chain of their release and distribution.
