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.

Today has been “Blog Action Day” and the theme this year is poverty. Coincidentally, that is the basic theme here in Des Moines at the 
This year’s winners are former U.S. Senators George McGovern and Bob Dole, who are responsible for legislation creating an international school-feeding program which has provided meals to feed more than 22 million children in 41 countries. They are pictured here during a dialogue held at the event with 2003 World Food Prize winner Catherine Bertini, former executive director of the World Food Program. 
Meet John Davis in case you haven’t. I meant to let you know earlier that he’s covering the Farm Foundation’s Transition to a Bio Economy: Environmental and Rural Impacts Conference in St. Louis this week while Cindy is in Des Moines at the World Food Prize Symposium and I’m at Sunbelt Ag Expo.
I got an overview of Sunbelt Ag Expo today. By overview I mean from the control tower for this airport which was formerly a military airfield. I climbed up and took a few photos early today.
Even though the word “crisis” is being used liberally here at the 
Conway stressed the need to address why we want to produce biofuels and the urgency to move quickly into second and even third generation biofuels – such as cellulosic ethanol from switchgrass and biodiesel from algae. “Maybe we should have a new World Food Prize on this,” Conway said. “In which we transform the world from one dependent on fossil fuels for energy and production of chemicals, into one that depends on plants as a basic source of our economy.”
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.
When it comes to farm show food booths, one that’s getting a lot of business at Sunbelt Ag Expo is Roasted Corn.
This is Justin Cremer, director of communications for the World Food Prize, at the door of the press room. Not too many media types here yet – more will be on hand for the bigger events, like the Laureate’s Forum tonight and the actual presentation of the World Food Prize on Thursday. 
One person who is here is Susan Carter – the newest member of USDA’s broadcast team. She took over the spot vacated by the legendary Brenda Curtis when she retired early this year. Susan has been on the job since May and while she is smiling in this photo, she has been experiencing some of the usual on the road headaches – flight delays and cancellations, internet problems and computer issues. Bless her heart – and she is still smiling.
The World Food Prize Norman E. Borlaug International Symposium is getting underway here in Des Moines with a couple of side seminars early this morning. The opening ceremony takes place at 1 pm central time. 
One of this morning’s seminars was hosted by USDA’s Foreign Agriculture Service, and since we didn’t have a speaker program for that event, I was surprised to walk in the room and see one of this year’s laureates, Hon. George McGovern at the podium. Wish I had known, I would have gotten a recorder on the podium because he had some very interesting remarks about the history of USDA and his role with Bob Dole in expanding and strengthening the school feeding program on a global basis. One of his comments was that he sees the role of USDA growing in the future to help feed a growing population. McGovern will be speaking at a forum this evening with Sen. Dole.
