With 60% of the world’s arable land, Africa has the potential to not only feed itself, but also to become a major food exporter. This enormous potential was demonstrated in an innovation by CGIAR scientists during Global Forum for Innovations in Agriculture (GFIA)—processing cassava peels into animal feed.
Processing high quality cassava peels into animal feed could reduce human-livestock competition for food-feed grains and help develop alternative and sustainable feed sources to boost livestock production in Africa.
With the right investment in scaling up, Africa’s estimated 50 million tonnes of cassava peel waste per year could generate at least 15 million tonnes of cassava mash.
Innovative agricultural solution aimed to create agribusinesses and contribute to wider economic prosperity. Unlocking this potential will require that Africa’s agriculture leapfrog traditional development challenges and leverage sustainable and inclusive agriculture as a driver for economic prosperity and global trade.
CGIAR scientists developed a low-tech way of transforming wet cassava peels into high quality, safe and hygienic feed ingredients within eight hours, producing one tonne of high quality cassava peel (HQCP) mash from three tonnes of wet peels.
Animal scientist at the International Livestock Research Institute (ILRI), Anandan Samireddypalle—based in Ibadan, Nigeria—explained the simple process. He explained how 98% of Nigeria’s cassava peels annually are wasted due to constraints associated with drying and concerns about safety of use, particularly hydrocyanide- and mycotoxins-related food poisoning. Drying peels outside, practically impossible during the rainy season, takes two-three days otherwise. Consequently, peels are left to rot in heaps or set on fire—both polluting the nearby air, soil and groundwater and wasting a potential feed resource.
With the right investment in scaling up, Africa’s estimated 50 million tonnes of cassava peel waste per year could generate at least 15 million tonnes of HQCP, substantially addressing shortfalls in the supply of animal feed and eventually creating a USD2 billion a year industry on the continent. Of course, safe and hygienic processing standards will need to be promoted among processors and users to allay safety, storability and other concerns. CGIAR scientists believe related research and development activities could facilitate about 20% of the sector’s potential transformation, so that further scaling could rely on private, and not donor, funding. The innovation was developed by the International Livestock Research Institute (ILRI), International Institute of Tropical Agriculture (IITA) and International Potato Center (CIP), with the support of CGIAR Research Programs on Root Tubers and Bananas (RTB), Integrated Systems for the Humid Tropics and Livestock and Fish, as well as the Global Cassava Partnership for the 21st Century (GCP21).
