The controversy over the issue is broad and there are a large variety of analyses due to the
diversity of focus and of interests involved. The FAO hadquestioned the high subsidies by rich
countries to the production of biofuels, which utilize 5% of grain production and contribute to the
price rise (CHADE, 2009, p. 25). The articles “How Biofuels Could Starve the Poor”, by Rudge and
Senauer, and “Food for Fuel?” with the participation of Dashle, both published in Foreign Affairs in
2007, strongly blamed biofuels for the rise in food prices. The controversy grew up with research
that attributed to biofuels an impact of 75% on grain food prices.
