Unusually heavy rains in Nigeria have resulted in at least 20 deaths around the city of Ibadan, 90 miles north of Lagos. A dam overflowed, and the fact that drains were clogged with rubbish made the inundation even worse.
Camps have been set up to accommodate the thousands of people who have been driven from their homes. Buildings have been flooded, food destroyed, and farmland swamped.
Last year, more than 100,000 people were made homeless by floods in the country, while across western and central Africa as a whole, more than 300 people were killed. The Niger river reached its highest level in 80 years, and there were severe food shortages in the aftermath of the flood, which affected half a dozen countries.
The African floods of 2007 were even more widespread, affecting 14 countries, disrupting the lives of 2.5 million people, and killing 250. (See also my blog of March 19, 2009)
