Nat Geo Explorer: Jerry Glover

Jerry Glover believes wheat could help feed a starving planet. He is an agroecologist, a scientist who studies the ecology of agriculture or farming. He's part of a research team working to develop perennials—plants that are alive year-round and can be harvested each year without being replanted. "Studying this helps us see how perennial crops of the future could be farmed with less effort, more nutritional value, and at the high yields we’ll need to feed a planet of seven to nine billion hungry people," says Glover. Unlike annual crops, which must be planted every year, perennials live on, enrich the soil with key nutrients, and require little or no fertilizer or pesticides.
