The discussion about hunger and poverty in developing nations turned largely from the controversies of global warming and genetically modified crops and focused on governments and their role in solving social ills.
Former British Prime Minister Tony Blair says all the money in the world cannot help nations unless they have basic capacity in the government to provide electricity, roads and policies that allow farmers to make their own decisions.
He says change is occurring with a new generation of leaders in Africa and elsewhere. They want to learn and incorporate new ideas about how to better grow food.
Blair appeared with philanthropist Howard Buffett, son of billionaire investor Warren Buffett, at the World Food Prize symposium in Des Moines to discuss ways to end poverty and hunger.
