Cost of eating going up because of supply, demand

Food prices are high worldwide and many factors are causing the increase, according to a Kansas State University agricultural economist.

"Prices are at high levels compared to what they have been in the past decade," said Sean Fox, professor of .

Prices of commodities are 30 to 35 percent higher than in 2010, according to the World Bank's food pricing index. A similar price spike occurred in 2008, but the levels are not fully equivalent.

The increased prices can be attributed to several factors based on supply and demand, Fox said.

"What has happened is that incomes have increased very dramatically in places like India and China, contributing to a very dramatic overall increase in demand for food commodities," Fox said. "That is a major driver on the demand side."

The world's population also has increased by 10 to 12 percent during the last 10 years, increasing the demand for food. But worldwide has been increasing by a greater percentage.

So why are not staying the same or lower?

Biofuel production has facilitated higher prices through greater demand for corn. Fox predicts 40 percent of the United States' corn output will likely be used for ethanol in 2011.

The greater emphasis on corn has caused decreases in wheat acreage, Fox said. Wheat also has suffered because of extenuating circumstances. Wheat stocks were lower worldwide and caused greater volatility in prices. Production concerns have been raised in the U.S. because of drought in the southern Plains and too much moisture in the northern Plains. Production concerns also are occurring worldwide because of equally unpredictable weather in China, France and Germany.

As with the food price hikes in 2008, are also playing a role, according to Fox.

"Higher oil prices contribute to increased demand for , which drives up the price of corn. This, in turn, brings up cereal prices as well," he said.

by exporting countries can also significantly alter the price of certain commodities. The Russian drought of 2010 caused a 30 percent decrease in domestic wheat production, Fox said. As a result, the Russian government enacted export controls.

"That increases the price for everyone else," Fox said.

The effects of higher-priced food commodities are far from universal. In Europe and the U.S., people spend a relatively small proportion of their incomes on food -- around 10 percent, Fox said. People in lower-income countries, such as in the Middle East and sub-Saharan Africa, spend a greater proportion of their income on food.

"If they are spending 70-plus percent of their income on food, a 15 percent increase in wheat prices or corn prices is a major issue for them," Fox said. "Higher grain contribute to an increase in global poverty. It's a major issue in some countries."

VD, I'm confused... I thought you'd be in favor of ethanol production (just as a touchstone - I'm not). And who are the "worthless bag of losers"? All of the U.S.?

There's no way for you to be a complete Luddite because, you know, you're using a computer an all... but for some reason "commerce" seems to really tick you off.

Please feel free to set me straight on this if you wish.

The increase in food prices is a real, global problem. If you think "supply & demand" is the problem, take a look at what horrors are caused by central planning and top-down government dictats.

That amount of the corn crop going to ethanol? This is not sustainable for a reason related to survival. I live in the midwest...as well as in the far west; and know that corn production by a farmer is often under contracts. These contracts enforce a monoculture on that farmer that locks him in financially to produce that corn every year. Until his soil dies and he goes broke. Corn production takes the 'life' if one wants to call it that, out of the soil. I have seen organic rich blackland farmland go light brown, fallow and almost infertile in less than twenty years of constant corn production. Farmers know better, but do this anyway in order to pay off loans for equipment, land, etc. that they were encouraged by unnatural potential profits from these 'lorelei contracts' to go out and financially entrap themselves for. Nature is not fooled. Banks run away with all the money and leave ruin in their wake...land eroded and dead, families in the streets, etc.
