A substantial impact on Africa agriculture can be made through research on crop improvement for the extensive inland valley agro-ecosystems (IVS) extending from the humid forest to the savanna zones in sub saharan Africa. Systematic surveys of farmers have shown that cassava is a favoured upland ...
