The major effect of flooding in Nigeria is the destruction of farms and houses. Flooding occurs when water overflows from its natural channels and covers the surrounding land. This can result in the destruction of homes, farmlands, and other properties, which can lead to displacement of people and loss of livelihoods. Flooding can also cause injuries and loss of lives, as well as the spread of water-borne diseases. The dumping of refuse along river channels can exacerbate the impact of flooding by blocking drainage channels and increasing the risk of flooding.
