Climate change is moving U.S. corn production north

The Corn Belt is moving north, proving to food producers across the country that this summer's drought was not a fluke. The most corn since 1937 was planted this year, but growers in Kansas planted the fewest in three years, turning instead to crops that are less water-intensive, including wheat and sorghum. But in Manitoba, corn acreage has almost doubled over the past decade.

This shift is "a glimpse of a future altered by climate change that will affect worldwide production," the Sydney Morning Herald of Australia reports. Changes are happening faster than plants can adapt, said Axel Schmidt, a former International Center for Tropical Agriculture scientist.

Agriculture businesses are adapting. Agribusiness Cargill Inc. is investing more in northern facilities in anticipation of increased production there. DuPont Co. is developing genetically modified corn seed that could withstand drought, and boosting research in sorghum and other crops.

U.S. corn was worth $76.5 billion last year, more than twice the value of soybeans and five times that of wheat. Most ethanol comes from corn, most livestock eats it, and high-fructose corn syrup is used in a mass array of products. While climate change will likely move its production north, the Midwest will probably remain the corn belt just because of its good soil and generally favorable weather, Illinois' Heritage Grain Cooperative manager Jerry Rowe told the Herald.
