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 >

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 >

An Interesting Coincidence?

The papers published in Science two weeks ago continue to make headlines, as a quick search of Google News will show. Also this week, oil reached the $100 per barrel mark. Meanwhile, debate over the Science papers continues, and some truths are out there, as we said when we began this public forum. Nathanael Greene of the Natural Resources Defense Council notes the media have made rather simplistic assessments of the Science papers.Greene writes that the Read More >

Scientists Respond to Carbon Debt Issue

Reaction to the ScienceXpress articles by Searchinger et al. and Tilman et al. has focused on the assumptions the teams of authors used in measuring greenhouse gas emissions from changes in land use. As Michigan State University Professor of Chemical Engineering Bruce Dale points out, Both of these papers are modeling studies and are therefore completely dependent on the validity of the models themselves and also of the basic assumptions and data input to the Read More >
