(Radio Iowa) – A federal report on the so-called “dead zone” in the Gulf of Mexico finds it’s much larger than initially forecast earlier this year. The report from the National Oceanic and Atmospheric Administration blames runoff from Midwestern farm fields for the massive area where there’s too little oxygen to support marine life. Iowa Farmers Union President Aaron Lehman (LAY-mun) says the state’s been working to address the growing problem. “It certainly is alarming,” Lehman says, “and I would argue that many of the strategies in Iowa’s nutrient reduction plan simply are not incentivized enough to get enough practices put in place on the farm.”

The NOAA report is concerning, Lehman says, and could lead to more regulations on agriculture. He’s hopeful that won’t happen and that government will work -with- farmers on their environmental practices. “We know that there’s some real difficult decisions that will be ahead,” Lehman says. “I’d much rather us make that investment with farmers, many, many of whom are doing exactly the right things, rather than jump towards a regulatory-only system that many others will recommend.”

Because there will likely be more regulatory pressures put on agriculture following this report, Lehman says it’s even more important the incentive fixes are made to the nutrient reduction strategy. “I think we’re going to see more and more calls for a peer regulatory approach rather than a mixed approach that’s built on investments for farmers,” he says, “which is all the more reason to start now, making those investments with farmers, because largely, we’ve done a good job on the farm.”

The NOAA report says the dead zone is ten times the size of New Orleans’ Lake Ponchartrain. The area off the coasts of Louisiana and Texas now covers more than 63-hundred square miles, about a thousand square miles larger than it’s been the past five years.
