The World Food Programme (WFP) is the food assistance branch of the United Nations and the world's largest humanitarian organization addressing hunger. It was established in 1961 and provides food to around 90 million people per year. In 2007, WFP and YUM! Brands launched the World Hunger Relief Week campaign, attracting nearly 35,000 restaurants worldwide and raising $16 million for hunger relief. Currently, WFP is working in the Horn of Africa region experiencing a severe drought and famine, aiming to feed one person per day for 50 US cents.
