Just three crops account for 60% of Africa’s calories, despite the continent being home to 30,000 edible plant species. With 20% of the African population facing hunger, over-reliance on maize, wheat, and rice increases the risk of famine, the climate scientist Tafadzwanashe Mabhaudhi wrote in The Conversation. Other hardy, nutritious plants, such as cowpea, pigeon pea, millet, and sorghum, which can grow in underused areas and tolerate heat and drought, could help end hunger in Africa. Research shows that small farmers with a wide range of crops are less susceptible to malnutrition. “Neglecting agrobiodiversity in favour of monoculture” has left farmers vulnerable to shocks, Mabhaudhi wrote: Governments should incentivize crop diversification. |
