The introduction of exotic crops, fruits and livestock into Africa was initially guided and informed by the way indigenous crops, livestock and fruits performed in different micro climates. Unfortunately, instead of cultivating co-existence between exotic and indigenous foods, the colonial knowledge system has sought to completely replace indigenous crops, fruits and livestock with exotic food systems A telling example is how African agronomists and horticultural specialists have been equipped with knowledge on promoting plantations of apples, oranges, peaches and other exotic fruits. They cannot imagine plantations of indigenous fruits like Masawu, Matohwe, Tsvubvu, Nyii and many others that respond well to a changing climate. In addition to maize and wheat, exotic leafy vegetables have also been over-researched such that there is no longer any new knowledge about these food commodities. On the other hand, thousands of indigenous crops, fruits and vegetables are yet to be researched and commercialised for the benefit of consumers.
