"Bioenergy Potential of the United States Constrained by Satellite Observations of Existing Productivity" Environmental Science & Technology


"While EISA energy targets are theoretically achievable, we show that meeting these targets utilizing current technology would require either an 80% displacement of current crop harvest or the conversion of 60% of rangeland productivity. Accordingly, realistically constrained estimates of bioenergy potential are critical for effective incorporation of bioenergy into the national energy portfolio."

"7 states fight California rule over ethanol carbon scores" USA TODAY



"The California rule considers Midwestern ethanol to have a larger carbon footprint. The judge said the rule unconstitutionally interferes with interstate commerce. California officials are appealing the decision.
The rule hinges on the concept of indirect land use change, Thorne said.

The idea is that if farmers in the U.S. sell their grain for ethanol, farmers in other parts of the world must grow more corn for the food supply, pumping more carbon into the atmosphere, he said"

Economic of Food Prices and Crises by Marco Lagi, Yavni Bar-Yam, Karla Z. Bertrand, Yaneer Bar-Yam


"The results show that the dominant causes of price increases are investor speculation and ethanol conversion."

"Spikes in Food Prices Project 2013" New York Times Green Blog


"The computer modeling that generated the prediction of a food crisis was first published by the New England Complex Systems Institute in September. The modeling has gained considerable credibility by accurately predicting food prices over the last 10 months. The research indicates that the crucial factors behind food price increases are the conversion of corn crops to ethanol and investor speculation on the agricultural futures market.
'There are two policy decisions we’ve identified as key drivers,' said Yaneer Bar-Yam, president of the institute. 'The first is the promotion of ethanol conversion, which provides the U.S. with less than 1 percent of its energy but has a much larger effect on global food availability.'"
