NCGA Questions Study On Climate And Corn Yield

Corn fieldA new study out of Rice University and the University of California at Davis that looks ahead 40 years at farming and climate change and draws some very specific conclusions needs to go back to the research table, according to the National Corn Growers Association.

“At a time when meteorologists struggle to tell you what the weekend will be like, it’s odd to see a report that tries to so specifically pinpoint the weather 40 years from now,” said NCGA President Pam Johnson. “But that’s only one of the problems we have with this very problematic study.”

The report, published in the American Chemical Society journal Environmental Science and Technology, states that the yield of corn grown for ethanol in the U.S. would be reduced by an average of 7% over the next four decades, and the amount of irrigation needed for the corn would increase by 9%. Among its other flaws, Johnson noted:

  • The news release that accompanies the report, which looks only at corn grown for ethanol, clearly states the bias of the authors, who “have long questioned the United States’ support of biofuels as a means to cut vehicle emissions,” the release said. It’s no wonder, then, that the report looks ahead a full four decades to criticize an ethanol policy, the Renewable Fuel Standard, which only cover renewable fuels for the next nine years.
  • The report ignores any possible advances in technology to improve corn growing, such as new agronomic practices or technology. “Looking back 40 years, corn farming was so different in 1973 than it is today, and it’s a difference that could not have been predicted back then,” Johnson noted. “The fact of the matter is, it’s not only naive to assume that corn yield will not increase as it has been, but our current average yield is already sufficient to produce the five billion bushels needed to meet the full conventional RFS volumes.”

Farmers have been successfully dealing with climate change on this continent for 2,000 years and have shown remarkable resilience and adaptation, Johnson said. Last year, even with a significant drought, they brought in the eighth largest crop ever and saw a significant yield increase compared to the last drought year. This shows that farming practices and tools will change to respond to changing conditions. Two examples offered by Johnson: Since 1980, corn farmers have reduced per-bushel greenhouse gas emissions by 36% – and irrigated water use by 53%.

“President Eisenhower once said that farming looks mighty easy when your plow is a pencil and you’re a thousand miles from the corn field,” Johnson noted. “We encourage academics to get out of their ivory towers and learn what farmers are really doing, instead of simulating information that is basically useless.”

  1. This article is "right on." Having been raised on a farm in the corn belt and worked in the academic field I couldn't agree more.

  2. this study and news release are not intended for corn growers, crop consultants or anyone associated with corn production. this has the singular purpose of trying to create or persuade political opinions of low information people that think food comes from the grocery store. it's all about political opinion and how this info can be used to manipulate and mislead for environmental regulation.
