Floods can have devastating consequences and can have effects on the economy, environment and people.During floods (especially flash floods), roads, bridges, farms, houses and automobiles are destroyed. People become homeless. Additionally, the government deploys firemen, police and other emergency apparatuses to help the affected. All these come at a heavy cost to people and the government
Earlier this year heavy rains and thunderstorms caused havoc in Lagos, Nigeria’s economic nerve centre and one of Africa’s most populous cities. Residents woke up in many parts of the city to find their streets and homes flooded and their property, including cars and other valuables, submerged.
Lagos has not been alone. Suleija, a town near the capital city Abuja hundreds of kilometres away, suffered its own flooding challenge in early July. Heavy rains washed houses away and caused others to collapse.
Although the degree and seriousness of flooding in Nigeria fluctuates, flooding remains a recurring phenomenon in most parts of the country. The first factor aggravating flooding is climate change, which has been shown to contribute to more extreme storms and rainfall. Another factor contributing to flooding in cities is that Nigeria has experienced rapid urban growth and planning is poor.
As most people are well aware, the immediate impacts of flooding include loss of human life, damage to property, destruction of crops, loss of livestock, and deterioration of health conditions owing to waterborne diseases. As communication links and infrastructure such as power plants, roads and bridges are damaged and disrupted, some economic activities may come to a standstill, people are forced to leave their homes and normal life is disrupted.
