ABUJA—A new survey on malaria prevalence among Nigerian children has revealed that four out of every 10 have malaria.

The survey conducted in 2010 by the National Malaria Control Programme, NMCP, and released in Abuja, yesterday, said the current ratio of malaria infection translates into 42% of Nigerian children that are infected with malaria.

The survey also indicated that the prevalence increased with age and decreased with wealth.

The cassava plant could help African farmers cope with climate change, a scientific report says.

"It's like the Rambo of the food crops," report author Andy Jarvis, of the Colombia-based International Center for Tropical Agriculture, said.

He told the BBC: "Whilst other staples can suffer from heat and other problems of climate change, cassava thrives."

The root crop is already one of the most widely consumed staple foods on the continent.

But the report also stresses the need for more research to make cassava more resistant to pests and disease.
