Promoters of bio-fuels need to come up with second and third generation energy crops that will not compete with food crops, African Development Bank (ADB) president Donald Kaberuka has said. Kaberuka has implored southern African countries to pool their resources and address the energy crisis through regional investment in energy infrastructure instead of trying to implement efforts individually. Featuring on the Zambian National Broadcasting Corporation, Kaberuka said Africa must be extra cautious about the promotion of energy crops. He said he was skeptical about the huge investments going into energy crops production for extraction of bio-fuels, because the move was diminishing food production to levels that, if not checked, the world would come to regret.
