From time immemorial, flooding has always been a major problem across Nigeria, with devastating effects on lives, properties, farmlands, and infrastructure. From Lagos to Lokoja, and Bayelsa to Benue, the story is the same; homes submerged, roads washed away, and thousands displaced. The yearly floods gets more terrible with the passing of time, affecting millions of people and causing billions in damages. Sadly, not much has been done and it has become an annual inevitable ritual.
One of the major causes of flooding in Nigeria is poor drainage and waste management. In cities like Lagos and Port Harcourt, many drainages are blocked with plastic waste, sand, and refuse. Even during light rain, streets become flooded. People build on waterways and floodplains without proper planning, and the government sometimes turns a blind eye until disaster strikes. Lagos state government, for example, has done notable works in demolishing illegal buildings on the waterways.
Another cause is the release of water from dams like the Lagdo Dam in Cameroon. The release of water from this dam leads to massive flooding across states in the North and Middle Belt, some states down south also get little of the hit has most water bodies overflow during this period. The fact that Nigeria’s buffer dam (Dasin Hausa Dam in Adamawa State) has not been completed over 40 years worsens the situation.
What Can Be Done to Prevent Flooding in Nigeria?
-
Proper Waste Disposal and Drainage Maintenance
Nigerians need to stop dumping refuse in gutters and drainages. Governments at all levels should invest in regular cleaning of drainages, especially before the rainy season. In Lagos, the state government has started aggressive desilting projects, but more needs to be done and sustained. There should be a public schedule for drainage maintenance in every local government area. -
Enforce Town Planning Laws
Building on natural waterways should be strictly prohibited. The FCT Administration and Lagos state government have regularly removed structures blocking the waterways in their territories. This bold move that should be replicated nationwide regardless of who the defaulter is. Proper urban planning is key to flood control. -
Complete the Dasin Hausa Dam
If Nigeria completes this dam in Adamawa, it will help absorb excess water released from the Lagdo Dam. This single project will reduce flooding in several states downstream. The Federal Government should make this a priority. Besides it really embarrassing to abandon such critical infrastructure for over 40 years with the coming and going of different governments. -
Early Warning Systems and Emergency Response
Agencies like NEMA and NiMet should continue to issue timely weather predictions and flood alerts. But beyond issuing warnings, there must be community-level sensitization and readiness to act. This cannot be overemphasized the emergency response needs to be worked on in order to minimize loss of lives and properties. -
Tree Planting and Reforestation
In some of the states up North where erosion and surface runoff worsen flooding, planting trees and protecting watersheds can help reduce the speed and volume of floodwater. Communities and schools should be encouraged to plant trees. -
Construct More Drainage Channels and Embankments
In flood-prone areas , more embankments, levees, and canals should be constructed to redirect and manage water flow. Local and state governments should include such infrastructure in their yearly budgets.
Flooding in Nigeria is no longer just a rainy season issue; it is now a national annual ritual. But with a good sense of personal responsibility, community action, and government commitment, we can reduce the damage and save lives. As it`s commonly said, "those who fail to plan plan to fail." Let’s plan well, act early, protect our land and save more lives.
