Irrigation development in Sub-Saharan Africa has lagged significantly behind that in other developing countries. Consequently, economic development and food security are also lagging behind. Since the mid-2000s there has been a resurgence in the willingness to invest in irrigation, and Sub-Saharan Africa has the largest potential of any developing region to benefit from it.

Several cassava genotypes were observed although there were few bred varieties. The wide diversity in the cassava landraces was a consequence of the action of the farmers in continuously abandoning and introducing cultivars into their system as they tried to select those cultivars that met their needs. These included extended in ground storability in remote areas, high lOOt yield, and earliness in high demographic pressure areas, low cyanogen level in specific areas where the sweet cassava type was needed, as well as their needs for pests/disease tolerance, and good processing qualities.
