KPLU 88.5’s “Humanosphere” blog reports on the World Food Prize symposium and Borlaug Dialogue taking place in Iowa this week, where “about 1,000 people, including many former heads of state and top agricultural policy folk, are gathered together to talk about … how to feed the planet’s growing population.” The blog examines the debate around a “new proposed Green Revolution for Africa,” led by “the Alliance for a Green Revolution in Africa (AGRA), which was launched largely thanks to support from the Bill & Melinda Gates Foundation,” and provides links to recent media coverage related to global food security and hunger (Paulson, 10/12).
