Can these super-crops feed Africa?

Africa's population is set to boom over the next few decades - reaching 2.5 billion people by 2050.

The African Orphan Crops Consortium has identified 101 traditional plants ripe for improvement and is using a DNA sequencing machine to speed up traditional cross-breeding.

It makes the plants more fruitful, drought resistance and disease tolerant.
