Roots and tubers are not cropped in the Tropics only.

Europe produces almost as much roots and tubers per head as Africa, but is far from consuming as much of them.

Europe has the highest consumption of potato world-wide, much higher than South America, the continent of origin.

Africa and Oceania have the highest consumption of roots and tubers per head.
