Biofuels production has quickly expanded worldwide as part of strategies to make energy economies “greener”. Climate change mitigation and energy security have been frequent rationales behind biofuel policies, but developing countries have also emphasized the social dimensions of this new sector, flagging the inclusion of smallholder farmers in fuel production chains and the potential for poverty alleviation and rural development. However, most studies on biofuels remain focused only on the economic and ecological aspects of biofuel production and utilization, often leaving social and equity dimensions overlooked or understudied—and claims of “pro-poor” development largely unchecked. This paper therefore sets out to examine how different developing countries have attempted to promote rural development through biofuel production, what social outcomes those strategies have created, and what lessons can be learned, such as in terms of biofuel policy design. This is done through a comparative analysis of the contexts of Brazil, India and Indonesia; three countries with important agricultural sectors that have put large-scale biofuel programmes in place.
