Since the 2007 food crisis, controversy has engulfed biofuels. Leading up to the crisis, world-wide interest in these fuelswhich include biomass, biogas, bioethanol, and biodieselhad been surging as states increasingly saw these as a way to meet greenhouse gas reduction targets and promote sustainable economic development. Now some consumers, notably in Europe, are scaling back demand as they worry that biofuels are responsible for increased food prices and deforestation. In contrast, some statesparticularly Brazil and the USA, the world's leading bioethanol producerscontinue to promote biofuel development, especially in developing countries. Partnerships arising from these efforts, we argue, reflect new patterns in the international political economy, where trade relationships among developing countries are strengthening, and where economic lines between developed and emerging developing countries are blurring. Given previously observed patterns of resource exploitation involving complex webs of North-South and South-South trade (such as for resources like palm oil in Indonesia), we anticipate that the emerging political economy of biofuels will repeat and reinforce many of these same environmentally destructive trends.
