Abstract
► Biofuel crops on cropland can displace food crops, reducing food supply and triggering indirect land use. ► Growing biofuel crops on non-crop marginal land avoids these problems. ► But US farmers expanded cropland by only 2% when crop profitability jumped 64% during 2006-09. ► So medium-term availability of marginal lands for biofuel crops is limited and costly.
