Corn and Soybean Production May Move out of Iowa in Coming Years Due to Warming Temperatures in the Midwest

The production of corn and soybeans makes up a huge part of Iowa’s economy, but studies show that warming in the Midwest caused by climate change may cause the ideal growing conditions for the crops to move north into Minnesota and the Dakotas in the next 50 years.

Researchers at Penn State University studied county-level crop-yield data from 18 states compiled by the U.S. Department of Agriculture’s National Agriculture Statistics Service over approximately a 30-year period. The team also studied weather patterns and the relationships between climate and corn and soybean yield over that same time period.

Their findings showed that this northward shift has already begun and is likely to continue if there is no intervention. This may be concerning to Iowans who rely on the production of these crops for their livelihood. However, the current changes are happening gradually, so farmers would have adequate time to adapt over the coming decades, according to Armen Kemanian, a researcher at Penn State.

Iowa farmers would have to begin growing a different variety of crops or switch to a system that involves growing two crops a year once corn and soybeans are no longer a viable option. The new crops would also need to have a lower sensitivity to extreme temperatures and changes in humidity to thrive in an environment with more extreme fluctuations in temperature caused by climate change.
