A Sorghum Renaissance?

All Things Considered:

Much of the world is turning hotter and dryer these days, and it's opening new doors for a water-saving cereal that's been called "the camel of crops": sorghum. In an odd twist, this old-fashioned crop even seems to be catching on among consumers who are looking for "ancient grains" that have been relatively untouched by modern agriculture.
Sorghum isn't nearly as famous as the big three of global agriculture: corn, rice and wheat. But maybe it should be. It's a plant for tough times, and tough places....
Today, American farmers grow two kinds of sorghum. Sweet sorghum is tall; you can use it to make a sweet syrup or just feed the whole plant to animals.
But most sorghum in the U.S. is grown for feed grain. That version of the plant is short, with seeds that come in several different colors.
Steve Henry showed me some near Abilene, Kan., on our way to the farm where he grew up. Kansas is the biggest sorghum-growing state. Out here, they call milo.
"You've got white milo, red milo, yellow milo," says Henry, scanning the field. "Basically, you have the little berries, and they're filled with starch, like like corn is filled with starch, and the starch is what we're after."
Sorghum is used for the same things as corn: high-energy feed for pigs and chickens. It also gets turned into ethanol...In the U.S., the amount of land in sorghum has been steadily shrinking.
There are signs, though, of a sorghum revival on the high plains. The reason is water, or the lack of it. From Nebraska to western Texas, cornfields have been fed with rivers of water pumped from underground aquifers, and that water is starting to run low.

When I was a kid and I saw lists of crops, I always wondered what milo was.  Well, now I know.  I remember going to visit my roommate from college in southern Illinois, and I was amazed how much sorghum was grown down there.  Here's a map from USDA showing the growing region of sorghum, and southern Illinois doesn't even show up:

I would anticipate much more sorghum will be grown in the High Plains in the future.
