Introduction

Flooding is no longer an occasional inconvenience in Nigeria; it has become a recurring national crisis. Year after year, lives are lost, properties are destroyed, and livelihoods are disrupted as communities struggle to adapt to increasingly severe and frequent flood events. From the overflowing banks of the Niger River to the waterlogged streets of Lagos, flooding now ranks as one of the most visible consequences of climate change and infrastructure neglect in Nigeria.

At ResearchGains, we set out to understand how everyday Nigerians are affected by flooding, not just in statistics, but in real experiences. We surveyed citizens across regions to gauge the scope of damage, their level of awareness, opinions on government response, and what they believe are the most urgent solutions.

The results are sobering, a clear indication that while awareness of the risks is growing, the structural and institutional response still lags behind. In this article, we present key insights, data interpretations, and a call for coordinated action to make Nigeria more resilient in the face of this growing environmental emergency.

Flood Impact by Region: Flooding Knows No Borders

When asked whether they or their households had been directly affected by flooding in the last 12 months, 35% of respondents in the South West said yes. This was followed by 25% in the North West, and 15% in the South South.

These numbers suggest that flooding is not isolated to coastal or lowland areas as often assumed, it is now a nationwide concern. That the South West leads in self-reported impact may be linked to high population density, poor drainage, and unregulated construction in urban centers like Lagos and Ibadan. The widespread nature of these experiences is a clear signal: no region is truly safe without deliberate planning and adaptation.

Types of Damage Experienced: Floods Leave More Than Puddles

The data reveals the real and multidimensional costs of flooding:

• 36% experienced property damage

• 24% lost crops or means of livelihood

• 11% were displaced from their homes

• Only 21% experienced no damage at all

This confirms what many Nigerians already know: floods are not just about water, they destroy homes, devastate farmlands, push people into poverty, and displace entire families. For a country where many people live paycheck-to-paycheck and depend on informal economies, the aftermath of floods can be catastrophic. Recovery is often slow or nonexistent, especially for rural and low-income communities.

Risk Awareness: Knowledge Exists — But Gaps Remain

Flood awareness is a critical factor in reducing harm, and the survey shows promising results:

• 44% report very high awareness of flood risks in their area

• 32% say their awareness is moderate

• 25% still report low or no awareness

While a majority of respondents feel well-informed, a quarter of Nigerians still live with little or no knowledge of flood risks. This is especially dangerous, as unawareness can lead to lack of preparation or failure to evacuate in time. Expanding public education campaigns, especially in rural and semi-urban areas, could dramatically reduce loss of life and property.

Government Response: Divided Perceptions, Unmet Expectations

When asked to evaluate the government’s response to the most recent flood in their area:

• 30% said it was not effective

• 28% felt it was very effective

• 8% said there was no government response at all

These mixed results reflect a troubling inconsistency in how disaster response is implemented across the country. Some areas receive aid and evacuation services, while others are left to fend for themselves. The absence of a coordinated national flood response strategy is evident, and Nigerians are noticing.

Urgent Solutions: What Nigerians Want Now

When asked what the most urgent solution should be to reduce flooding in Nigeria, respondents were clear:

• 36% called for proper drainage systems

• 19% want early warning systems

• 17% support relocating at-risk communities

The call for improved drainage highlights the everyday reality: poorly maintained or non-existent stormwater systems are a primary cause of urban flooding. Meanwhile, the desire for early warning systems and strategic relocation shows that people are ready to adapt, if supported. These are not abstract policy demands; they are practical, actionable needs voiced by those directly affected.

Conclusion: Flooding is a National Emergency — Not a Seasonal Headline

This data tells a powerful story: flooding is real, destructive, and getting worse, yet the national response remains fragmented and reactive. From Lagos to Sokoto, Nigerians are bearing the burden of poor infrastructure, insufficient planning, and a lack of coordinated leadership.

But the numbers also reveal something hopeful: people are paying attention. Awareness is growing. Communities are demanding better. And there is a collective understanding of what needs to be done, better drainage, proactive risk communication, and climate-resilient development.

At ResearchGains, we believe in the power of data to drive action. We will continue to ask the right questions and amplify the voices of ordinary Nigerians, because their lived experiences are the starting point for real change.
