A recent article in the New York Times about a new movement among farmers (mostly in New York State) to begin growing wheat and milling it into flour for local bakers.

Today, nearly all of the nation.s wheat is grown on vast fields and milled in factories in the Midwest. Over the past few years, though, farmers and millers like Mr. Earnhart and Mr. Lewis have begun restoring wheat fields and reviving flour mills around the country.

Here is a link to an interesting report authored by the USDA. From the intro to the report:

World market prices for major food commodities such as grains and vegetable oils have risen sharply to historic highs of more than 60 percent above levels just 2 years ago. Many factors have contributed to the runup in food commodity prices. Some factors reflect trends of slower growth in production and more rapid growth in demand, which have contributed to a tightening of world balances of grains and oilseeds over the last decade. Recent factors that have further tightened world markets include increased global demand for biofuels feedstocks and adverse weather conditions in 2006 and 2007 in some major grain and oilseed producing areas.
