If all the food produced in the world were divided equally, there would be plenty for everyone--with some to spare-- says the National Committee for World Food Day. But food is not effectively proportioned, and one in 10 of the world's people goes hungry, according to the committee.

This Tuesday marks the fourth annual observance of World Food Day, an international event marking the founding of the Food and Agricultural Organization (FAO), an arm of the United Nations. Involving close to 150 countries, activities held worldwide include agricultural policy debates, food drives, seminars, discussions of social responsibility and family nutrition, all in the hopes of raising awareness about hunger on an individual, community, national and international level.

Among the activities being held for World Food Day in Washington are:

Mickey Leland (D-Tex.), chairman of the House Select Committee on Hunger, will discuss the food crisis in Africa, U.S. policies on world hunger and the role of women in agriculture. The show can be watched locally at the University of Maryland at Baltimore County, Academic Four Bldg., Room 303, Catonsville, Md., Tuesday from noon to 3 p.m., 301-962-8333.
