The contribution of IITA improved cassava to food security in subSaharan Africa: an impact study
Striga hermonthica (del) Benth is threatening rural livelihoods in western Kenya where maize is the major food and cash crop. Vulnerability analysis was conducted on a sample of 802 households in eight districts of Nyanza and Western provinces. Farmers perceived Striga as the major cause of pover...

A significant proportion of wheat flour can be replaced by cassava flour in the making of bread with little changes in the quality of bread. This paper shows that it is possible to make bread without using wheat flour. Soybean flour can also be mixed with cassava flour to increase the protein con...
Cassava production in Africa has increased by 12.5% between 1988 and 1990 with Nigeria becoming the largest cassava producer in the world. Almost all of the African cassava production is destined for human consumption. The consumption of cassava is sometimes associated with toxicity due to its cy...
Manihot esculenta Cyanogenesis, the ability to produce hydrogen cyanide (HCN), is common to over 2000 plant species. In cassava, two cyanogenic glucosides, linamarin and lotaustralin, are produced in the leaves and stored inside vacuoles. Linamarase, an enzyme capable of hydrolyzing the glucoside...
In almost all countries of the cassava belt in Africa, from Senegal to Mozambique, cassava leaves are consumed. In much of East Africa, all of Central Africa and parts of West Africa (e.g. Sierra Leone, Liberia), cassava leaves are a major component of the diet and constitute a very significant s...
This paper is based on information collected from about 600 villages in the ten largest cassava-producing countries within the framework of the Collaborative Study of Cassava in Africa (COSCA). The objective of the paper is to show that growth in cassava production in the region will depend more ...

Cassava roots, a major food in Africa, contain cyanogenic glucosides that may cause toxic effects. Malawian women farmers considered fields of seemingly similar cassava plants to be mixes of both ‘cool’ and ‘bitter’ cultivars. They regard roots from ‘cool’ cultivars as non-toxic. Roots of ‘bitter...
