Global food demand is expected to at least double - if not triple - over the next 50 years, according to Alex Avery, director of research, Hudson Institute's Center for Global Food Issues.
With a peak global population estimated at 8.5-9.5 billion in 2050, crop land and/or yields will have to increase in order to meet the increased demand for food. The greatest population growth is expected to occur in Asia and India.
But the United States and some South American countries have more arable land, creating export opportunities, Avery notes.
In addition to rising populations, increasing affluence across the world is allowing more people around the world to improve their diets, allowing them to diversify the grains and oils they consume and add more meat, milk and eggs.
