Today's NPR story by Richard Harris and related article by Tim Searchinger et al. highlight exactly the concerns with global biofuel production that prompted us to put in our grant (with Norm Miller and Dave Sunding) to BP and EBI on campus. What are the social, economic and environmental tradeoffs associated with widespread biofuel growth? How can we plan to spatially optimize use of landscapes so that increased carbon emissions do not result? Anyway, cool stuff.
