Midwest Drought Continues

At what point does a drought become a famine?

From the Columbia Tribune:
Those outside of the winter wheat growing region might not be thinking about the recent U.S. drought this time of year, but precipitation is desperately needed to recharge the aquifer and replenish subsoil moisture in Kansas, Nebraska and north Texas. This region is just west of the states that sustained the worst dryness in recent history in the Corn Belt this past growing season.
The latest version of the Palmer Drought Index shows much of Kansas and Nebraska dealing with extreme drought conditions with more than a 9-inch precipitation deficit. This area of North America produces hard red winter wheat used primarily for flour for breads.
