摘要：World trade in food grains (wheat, rice, and wheat flour) more than doubled from 1962 to 1983, while the number of countries participating in world trade increased 85 percent. Food grain consumption has increased faster than production in most countries so more countries entered world trade for their food needs, thereby increasing the volume and changes the patterns of world trade in food grains. This report is based primarily on the United Nation's world trade data and foreign trade statistics of countries not reporting to the United Nations.
