Trying to Define the Indirect Land Use Issue

Michigan State University Professor of Chemical Engineering Bruce Dale recently sent a letter to colleagues interpreting the analyses by Searchinger et al. and Fargione et al. in Science. In the letter, Dale says, “The Searchinger and Fargione argument at its root is this: corn (and perhaps cellulosic) ethanol is not sustainable because it will divert land use for animal feed (over 70% of corn is fed to animals) to new lands that will release large Read More >

Meet the Press (Or at least their editorial boards)

Recently two editorials were written by the NY Times and Washington Post concerning biofuels in which the recent Science papers were referred to. According to the NY Times, “The studies’ authors say that some ethanol sources wood wastes, or grasses planted on previously degraded land — could yield net benefits in terms of greenhouse gas emissions. Still, they are one more reminder that regulators will have to design the tightest possible standards for ethanol production. Read More >

Tilman clarifies study

Much of the media coverage of the recent Science Magazine studies made it clear that many hadn’t actually read the studies before they reported on them. Some interpreted the studies as condemning corn ethanol production now, not as the worst case scenario of what could happen in the future. University of Minnesota professor David Tilman, an author of one study, clarified it today in an interview with Minnesota Daily: Tilman, who is currently on sabbatical Read More >

Is the Debate on Land Use Over?

The full implications of the German Marshall Fund and Nature Conservancy articles in Science and the agenda and arguments of environmental and conservation advocates are coming more into focus. Consider comments posted by Nathanael Greene of the Natural Resources Defense Council on his Switchboard: While we still do not have international protocols that pay to protect or simply prohibit clearing of carbon rich lands, emissions from cleared land driven by marginally higher demand is simply Read More >

Biofuels Feedstocks – Yield Matters

The following post was submitted by Richard Hamilton, president and CEO of Ceres, Inc. Technology is playing a critical role in maximizing the inherent advantages of dedicated energy crops. Through advanced plant breeding, public and private researchers are increasing yields both in terms of tons per acre (field yields) and in terms of gallons per ton (through traits that improve conversion). Higher yields not only have a significant impact on reducing production costs of cellulosic Read More >
