“Welcome to climate change, Iowa-style” -Art Cullen
Over the course the current midterm election campaigns, Iowan farm fields have faced high heatwaves, record-breaking rainfall, flooding and unseasonable cold. Experts say such extreme events are fueled by climate change.
“Few politicians in the five states around here are talking about regulating agriculture in an era of warmer and wetter nights and long droughts,” he wrote. “Yet farmers are paying attention.”
Cullen based his argument in the findings of regional climate researchers. An Iowa State scientist predicted Iowa’s recent floods 20 years ago. Someone at the University of Minnesota predicts Iowa’s corn yield will halve by 2070. An agronomist, also from Iowa State, said soil erosion is making corn starchier and less valuable.
To combat the change, farmers have historically increased drainage tile. Cullen cited the environmental consequences of that adaption, mainly low oxygen due to excess nutrients in the Gulf of Mexico, and water quality issues within the state.
As the situation has gotten worse and awareness has risen, farmers have started making positive changes, too, Cullen said. They’re looking at sustainability reports, cover cropping to reduce erosion, and rotating diverse crops and livestock.
Cullen calls for policy makers to “catch up” and provide more financial aid to help farmers implement sustainable practices and even retire land.
