Experts want to change the habits of farmers on the continent

ATAKPAMEY, Togo - One by one, Ali Kassim pulls out the weeds that have grown in his rice paddy. It's surprisingly rare in Africa, but he is cultivating African rice - once close to extinction after it was pushed aside centuries ago for a higher-yield imported Asian variety.

Researchers hope to see more and more farmers like Kassim, who is 32 and among about 100 people in Togo's central Atakpamey region to take part in an experimental programme led by the Africa Rice Centre (AfricaRice), based in neighboring Benin.
