The World Food Prize was conceived by Dr. Norman E. Borlaug, recipient of the 1970 Nobel Peace Prize. Since 1986, The World Food Prize has honored outstanding individuals who have made vital contributions to improving the quality, quantity or availability of food throughout the world. Laureates have been recognized from Bangladesh, Belgium, Brazil, China, Cuba, Denmark, Ethiopia, Ghana, India, Israel, Mexico, Sierra Leone, Switzerland, the United Kingdom, the United Nations and the United States. In 1990, Des Moines businessman and philanthropist John Ruan assumed sponsorship of The Prize and established The World Food Prize Foundation, located in Des Moines, Iowa. The World Food Prize also annually hosts the Borlaug Dialogue international symposium to bring the world's foremost experts together to discuss cutting-edge issues in food security, and multiple youth education programs to inspire the next generation to study and work in fields related to global agriculture.
