The amount of water that goes into growing the corn that goes into ethanol has been a big topic of conversation between those for and against production of the green fuel. That’s why it is a topic of conversation at the Farm Foundation’s Transition to a Bioeconomy: Environmental and Rural Impacts Conference in St. Louis this week. This gathering of government officials, academics and industry leaders is designed to take on the tough questions facing Rural America as it moves to a bioeconomy.
One of the people in the ethanol/water discussion is Noel Gollehon, a senior economist with the USDA’s Natural Resources Conservation Service. He says the amount of irrigated corn is particularly concerning.
“About 15 percent of corn that is in counties that have ethanol plants is irrigated.” He adds that it takes 2,500 gallons for a bushel of corn. Now, while a large amount of that is grown in areas that uses the natural rainfall, what is worrisome is the corn grown in the drier western plains, where it equates to 750-1,000 gallons of irrigation water for each gallon of ethanol using irrigated corn as a feedstock. He says the answer might be cellulosic ethanol. However, he says it is no panacea and might be just as damaging to finite underground water sources.
“Working through this transition (to a bioeconomy), we have to use what we have,” says Gollehon. “But as we look forward, we hope we can develop cellulosic-based ethanol that doesn’t rely on that type of crop that has to be irrigated in those environments.”
Gollehon says we’ve been irrigating in this country for about 100 years, and if we want, we can keep doing that until all the water is gone… if we want to go down that route. But he believes that conversations, such as this one at the Farm Foundation’s conference, coupled with new technologies will get people to look at longer-term sustainability.

The keynote speaker for the symposium kickoff Wednesday was Sir Gordon Conway, who is chief scientific adviser for the UK. He talked about the spike in food prices over the past year and listed at least ten underlying causes, demand for biofuels being only one and he did not single it out as being a major culprit. He also pointed out the increasing global population, higher per capita income, increased demand for meat, higher prices for energy and fertilizer, and a shortage of arable land as some of the other factors.


You don’t have to agree to come up with agreeable solutions… that seems to be the theme for the latest Farm Foundation Transition to a Bioeconomy Conference.
President of Farm Foundation, Neil Conklin, says bringing together a diverse group of government, academic and industry leaders, who might not agree on everything, is key to the success of these forums.
How we develop rural jobs as the country moves to a bioeconomy was the latest subject tackled today at the Farm Foundation’s Transition to a Bioeconomy: Environmental and Rural Impacts Conference in St. Louis.
One of the key speakers during this session was USDA’s Under Secretary for Rural Development Thomas Dorr, who talked about how we need to move forward and be aggressive… even in light of the recent stock market turbulence.
How do we meet carbon reduction goals?
One of the presenters, John Reilly from the Massachusetts Institute of Technology (MIT), says we must be careful we’re not expanding one environmentally-friendly source just to infringe on another area of the environment.
A fascinating discussion this morning at the opening session of the Transition to a Bioeconomy: Environmental and Rural Development Impacts conference here in St. Louis.
Kitty Smith with the USDA’s Economic Research Service and chair of the “The Bioeconomy & the Environment” session says biofuels, such as ethanol and biodiesel, are a much better alternative to non-renewable fossil fuels.
The latest in a series of Farm Foundation-sponsored meetings on how to transition the country to a bioeconomy is about to get underway this morning in St. Louis, Mo.
