Virtually all global yam production takes place in the developing world. According to the International Institute of Tropical Agriculture (IITA) a majority of this production (90%) takes place in the 'yam zone', comprising Cameroon, Nigeria, Benin, Togo, Ghana, and Côte d'Ivoire. Yam is a very important crop for food security because of its excellent storage properties; it can be stored for four to six months without refrigeration and provides an important food safety net between growing seasons.
