Sub-Saharan Africa produces more than 50 percent of the world’s cassava (aka manioc, Tapioca, and Yucca), but mainly as a subsistence crop. Consumed by about 500 million Africans every day, it is the second most important source of carbohydrate in Sub-Saharan Africa, after maize. The leaves can also be consumed as a green vegetable, which provides protein and vitamins A and B. As an economy advances, cassava is also used for animal feed and industrial applications.
Described as the “Rambo of food crops” cassava would become even more productive in hotter temperatures and could be the best bet for African farmers threatened by climate change.
Cassava is drought resistant, can be grown on marginal land where other cereals do not do well, and requires little inputs. For these reasons it is grown widely by African small and poor farmers as a subsistence crop. However, cassava’s potential as an income-earning crop has not been widely tapped.
Cassava presents enormous opportunities for trade between areas with food surplus and food deficit. Currently, a large shortfall of the regional food supply is filled by cereals bought in the international market. For cassava to become an income-earning crop at intra-regional market for small farmers in Africa, two main obstacles remain: post-harvest processing and regional trade barriers.
