"Most recent African indigenous knowledge (IK) literature, especially in agriculture, emphasizes that Africans are informed innovators. This literature is filled with success stories. Excellent examples of local innovations and discoveries include crop breeding, grafting against pests, water harvesting, soil management, conservation and processing. Indigenous agricultural innovations have continued to be important as most of the locally-grown food is for local consumption. In Nigeria, for instance, the informal agriculture sector, mostly using indigenous methods and techniques, has an estimated worth of about US $12 billion, providing income for an estimated 81 million people." |
