Washington (CNN) -- The campaign to feed the world's poor will get some much needed star power Friday when Bono, co-founder of the global advocacy organization ONE, arrives to rally leaders of the Group of Eight industrialized nations to take action. While the crisis in the eurozone will no doubt top the agenda when the G8 leaders gather Friday for a two-day summit, the talks will also tackle the issue of food security and ways to feed a growing world population. At their annual summit in L'Aquila, Italy, in 2009, leaders pledged to provide $20 billion to fight hunger in the developing world over three years. Since then, U.S. President Barack Obama and Secretary of State Hillary Clinton have embraced food security as a signature foreign policy issue, working to support farmers in Africa and other developing countries to improve agriculture.
