(correct me if im wrong) you're data implies that china is causing a shortage in world food supplies, hence the rise in prices. but as far as i know, the increased demand for biofuels didn't come from china. it came from the developed world :$

I used to make ethanol on a commercial scale.

Now, I travel around and audit ethanol plants and give them tips for improving output and efficiency.

They all want to make more $ by making more gallons.
Top of my agenda is telling them how they can make equal profits by making the same # of gallons, and decreasing a few million btu's of input.

China's meat consumption change uses more grain than US ethanol industry, Biofuels Digest study reports-

The change in Chinese meat consumption habits since 1995 is diverting 2.9 billion bushels of grain to livestock feed — more than the entire 2.3 billion bushel harvest used to make US ethanol.

There has been a swirling controversy over what is driving up the price of corn, and prompting the switch of soy or wheat acreage to corn in recent years. Most observers have concluded that failed wheat harvests, increased demand for food in India and China, and the rising use of corn for biofuel production in the US, were all factors in the rise.

But how much?





China’s meat consumption increase began in the early 1980s. As early as 1995, annual meat consumption was increasing at a 12 percent annual rate. Consumption had been 16 kilograms per person 25 years ago, in 1983, according to the World Resources Institute.
In 1995, meat consumption was 25 kilograms per person, and reaching 31 kilograms by 1999, 50 kilograms by 2000, and is 53 kilograms per person today.

China meat consumption 1995
China Population in 1995: 1.203 billion
Meat consumption per capita: 25 kilograms
China meat consumption: 30.075 million tonnes
Average kilos of grain to produce a kilo of meat: 5
Grain needed to support meat consumption: 150.375 million tonnes

China meat consumption 2008
Population in 2008: 1.321 billion
Consumption per capita: 53 kilograms
China meat consumption: 70.013 million tonnes
Average kilos of grain to produce a kilo of meat: 5
Grain needed to support meat consumption: 350.065 million tonnes

Change in China meat consumption 2008
Change 1995-2008 in meat consumption: 39.938 million tonnes
Change 1995-2008 in grain consumption: 199.69 million tonnes

Policymakers have also cited food riots in Mexico over rising tortilla prices as evidence of a distortion in the markets caused by ethanol’s demand for corn.

Mexican corn consumption 1993-2007
Mexican population increase since 1993: 19 percent
Mexican corn production increase since 1993: 18 percent
Mexican corn consumption increase since 1993: 57 percent
US exports, as share of Mexican white corn (tortilla corn) market in 2007: 14 percent

Mexican corn production increases are keeping up with population increases, but falling rapidly behind in terms of meeting increased caloric demand. [ the world is getting fatter ] With US exports accounting for only 14 percent of the white corn market, and with US ethanol using yellow field corn, not white tortilla corn, the impact of the US ethanol industry on Mexican tortilla prices is negligible.
