FloodAlert: More Floods Will Happen In Lagos, Other States – Federal Government Warns

The late commencement of the rains, the monsoon wind that usually brings heavy rain in the West African coast, and the rising sea levels due to the melting of glacier in the polar region will further increase floods in states like Lagos, Rivers and Cross River, among others, the Federal Government has said.

In the latest flood alert advice prepared by the Federal Ministry of Water Resources for the country, the Minister of Water Resources, Mr. Suleiman Adamu, stated that the Nigeria Hydrological Services Agency, a parastatal of the ministry, had earlier come out with the flood outlook for the country on June 13, 2017.

Adamu stated that the summary of the alert was that approximately 30 states and over 100 local government areas were categorised as high flood risk areas and therefore should expect flooding.

He said,
“In the coastal areas, including Lagos, Port Harcourt and Calabar, possible coastal flooding in these places were mentioned in the NlHSA’s flood outlook. However, the case of Lagos State is unique, because it is very low-lying and there is reclamation of wetlands, which ordinarily should be buffers for floods.
“In addition, the rapid urbanisation of the Lagos coastal areas has not been matched with robust drainage provisions as well as adequate seawalls/barriers along the sea stretch.
“It is also important to mention that the monsoon wind (a strong prevailing wind that brings rain), which usually arrives the West African coast around June 22 to September/October, brings in a lot of rain to the land, coupled with the sea rise due to the melting of the glacier in the polar region.”
The minister added,
“All these are definitely increasing the amount of water in the low-lying coastal areas of Lagos State. Worthy of note is the fact that the rains did not start early this year, thereby possibly causing long duration torrential downpour and causing unexpected urban/flash floods in areas with non-existing or inadequate drainage systems in the country.”
