Lagos Flash Flood: How Poultry Farmers Can Take Climate-Resilient Agriculture Seriously

One of June 2026's viral videos shows a poultry farmer in Lagos State whose farm was devastated by a flash flood, with several birds lost and structures submerged. His claim of losing over ₦18 million in a single day is not only heartbreaking but also a reminder of the unpredictable impacts climate disasters can have on agribusiness.

It is a devastating story, but not a strange one. Flood disasters have been destroying farms and farmers' livelihoods across Nigeria in the last five years. Aside from the devastating flood disasters of 2021 and 2022 that claimed the lives of many Nigerians and destroyed their homes and livelihoods, Nigerian farmers are still facing shocks from continued flood disasters. According to a report by SBM Intelligence, between July 2024 and June 2025, widespread flooding in more than 30 states destroyed an estimated 180,000 hectares of cultivated farmland nationwide.

These cases haven’t stopped since then. Weather authorities, such as the Nigerian Meteorological Agency (NiMet) and related ministries, have especially warned of increased rainfall in 2026 while advocating for climate-resilient agriculture as the way out for farmers.

The uncomfortable truth this incident points to is not that a farmer has bad luck. It is most likely that a farm-establishment model built for the rainfall patterns of a decade ago is no longer a safe bet for today's rainfall patterns. 

The rain has changed. Has your farm?

NiMet's 2026 Seasonal Climate Prediction, released in February, forecasts above-normal rainfall for Lagos and many other states across Nigeria, with a rainy season starting earlier and ending later than usual. The projected annual rainfall in Lagos specifically reaches roughly 2,010mm in Badagry and averages around 1,965mm across the state's 20 local government areas.

The Lagos State Ministry of Environment and Water Resources built on this in a public briefing in March, projecting a wider range of between 1,650mm and 3,030mm depending on location, and confirming an early onset and delayed cessation of the rains for the state this year.

NiMet's own seasonal outlook ties this shifting pattern to broader changes in climate dynamics where established weather patterns are no longer the norm for several regions of the country and even the world at large. The result is not just more rain, but rain that is heavier, more erratic in timing, and increasingly likely to overwhelm infrastructure and farms designed around older, steadier assumptions.

This is what climate-resilient agriculture is actually a response to. The United Nations Food and Agriculture Organisation (FAO) defines climate-smart (climate-resilient) agriculture around three interlocking goals: sustainably raising productivity, building resilience to climate shocks, and reducing the practices that worsen climate change.

For poultry farms (and many other farms too), the resilience piece is the urgent one. It means treating flood exposure, heat stress, and climate-induced disease pressure as the core of planning and operational activities rather than emergencies to be improvised around after a loss.

How exposure actually shows up in a poultry house

As a livestock farmer who deals in birds that are vulnerable to water and highly humid environments, increased rainfall is a reality to plan against. That is what the Lagos incident clearly illustrated. Birds on the lowest tiers, closest to the floor, died in place while upper-tier birds barely survived. Beyond that, feed, drugs, and equipment stored at ground level will also compound the loss, often destroying the working capital a farmer needs to begin recovery.

But flash floods are the dramatic, visible end of a much broader rainfall-driven risk, and the quieter end of that spectrum may be doing even more damage in the long run.

An extended rainy season means a steady humid environment for a long time, and high humidity is not a comfortable climate for birds.  It affects their health and their productivity.

Research on broiler physiology shows that elevated relative humidity limits a bird's ability to cool itself through evaporation, intensifying heat stress even when temperatures themselves aren't extreme, and pushing respiratory rates and physiological strain higher. 

High humidity also keeps litter wet: manure fails to dry properly, ammonia concentrations climb, and that ammonia irritates the respiratory tract, raising the incidence of tracheitis and secondary bacterial infections.

Damp, poorly ventilated conditions likewise favour the growth of moulds and bacteria in litter and feed, further compounding respiratory and gut health problems. None of this necessarily requires a flood, as a longer, wetter rainy season delivers it by default.

The operational strain on farms follows naturally. A humid environment places serious pressure on poultry farms. Birds eat more feed but gain less weight because of stress, reducing feed conversion efficiency and lowering productivity. Mortality rates may also increase, leading to financial losses. Farmers often spend more on medicines and veterinary care to treat sick birds.

A wet environment can also damage stored feed, as damp storage conditions encourage mould growth, increasing the risk of aflatoxin contamination. Water sources such as boreholes and wells located in low-lying or flood-prone areas can also become contaminated, putting birds at greater risk of disease.

With all these in mind, practising climate-resilient agriculture is the only way for farms to survive going forward.

What a climate-resilient poultry farm actually looks like | step by step

1. Siting — get this right before anything else is built. 

No structural fix can compensate for building on the wrong land. So before committing to a site,  farmers must get an elevation assessment relative to the surrounding area and any known flood history. 

Treat proximity to drainage channels, wetlands, or reclaimed swampland as red flags. They should be equally important as the attractiveness of the land's price. 

Where available, cross-check a prospective site against state drainage and flood-risk maps, and take annual seasonal rainfall forecasts and briefings very seriously in your planning and decision-making.

2. Structural design — build in a margin against the water you haven't seen yet. 

Raise pens, cages, and housing platforms above the highest recorded flood line for the area, with an added allowance given that "highest recorded" is now being broken almost every week. Store feed, drugs, and electrical equipment on elevated racks, never directly on the floor.

It is also very wise and important to build perimeter drainage channels around housing units. Also, fit drainage outlets with non-return valves so floodwater can't back up into the farm through the very channels meant to protect it.

For ventilation and cooling systems, factor humidity control, not just temperature control, into the design brief from the start, since the two problems compound each other.

3. Operational protocols — turn forecasts into a standing procedure. 

Climate-smart farmers subscribe to and actually act on NiMet's short-range advisories, not just the annual Seasonal Climate Prediction. Daily and weekly outlooks will tell you a red-alert rainfall event is 24–48 hours away. 

Build a written, rehearsed evacuation protocol for moving birds to higher ground or temporary shelter when such an alert is issued. This is very important because a plan drawn up after the water is already rising is not a plan. 

Keep pumps and backup power tested and ready ahead of the peak flood months, and build humidity monitoring and litter management into daily routines through the wet season, not just temperature checks.

4. Financial preparedness — plan for the loss you hope never happens. 

There are agricultural insurance schemes covering flood and livestock in Nigeria, although uptake among small and mid-scale poultry operators remains low. This may be due to cost, unfamiliarity with claims processes, or simple unavailability of tailored livestock products in some areas. 

Investigating and budgeting for appropriate cover, even partial, is now a resilience decision on par with any structural investment. Alongside insurance, maintaining basic financial records and loss-documentation habits, like receipts, stock counts, photographs of infrastructure, also means that if disaster does strike, a claim or emergency support application won't be difficult to assemble.

For the farmer already underwater

While none of the above helps the farmer whose cages are already empty and whose losses are already counted in the millions, recovery needs to be sequenced rather than rushed.

The following three-step strategy will really help.

Immediate measures.

Ensure electrical systems are safely disconnected before anyone re-enters the site. 

Separate surviving birds from the dead, and have a veterinarian assess survivors for stress- and water-related illness before making any decisions about their future.

Any birds unlikely to recover should be culled and disposed of using proper biosecure methods. Bury or incinerate the birds according to guidance; never discard them into drains or waterways, as these methods compound the risk of contaminating the surrounding area.

In the following days.

Treat every water source on the farm as contaminated until tested, and do not reintroduce birds to any pen or house until full disinfection. Document everything with photographs, veterinary reports, feed and equipment losses, purchase receipts, for any insurance claim and potential state or association-level emergency support schemes.

In the following weeks to months.

Resist the pressure to restock to full capacity immediately. A phased restocking approach, beginning with a fraction of prior capacity and scaling up as infrastructure repairs and biosecurity measures are confirmed sound, protects against a second wave of losses from disease or from cutting corners under financial pressure. 

This is also the point to build in the structural and siting changes outlined above. This time, a rebuild is, in effect, a second chance to design the farm correctly rather than restore it to the same vulnerable state.

The bottom line

The Lagos flood that destroyed one farmer's ₦18 million investment is not an isolated misfortune; it is a preview, arriving in a year that meteorologists explicitly forecast would bring above-normal, longer-lasting rainfall to the state. 

Climate resilience in poultry farming isn't an abstract policy phrase; it is a checklist that starts with where you build, extends through how you build and operate, and ends with whether you can survive the year a flood actually reaches your farm.
