Akinwumi Adesina, president of the African Development Bank, is this year’s winner of the $250,000 World Food Prize.
He is the son of a farm worker who rose to head the bank where he made sure loans were available to improve agriculture.
He said the future of global food security relies on making farming in Africa a profitable business and developing local food processing. Adding value to agricultural products helps lift farmers out of poverty.
"I believe that what Africa does with agriculture and how it does it is not only important for Africa but it's important for how we're going to feed the world by 2050 because 65 per cent of all the uncultivated arable land left in the world is in Africa," he said.
"To help Africa get it right in agriculture is also going to be a key part of securing food for the world."
African nations, such as South Sudan, are now in the midst of the worst famines in 75 years, but it's wars, not farming technology or profitability, that are the reason.
