Stop biofuels to fight world hunger, food scientists say
Some top international food scientists Tuesday recommended halting the use of food-based biofuels, such as ethanol, saying it would cut corn prices by 20 per cent during a looming world food crisis.
But even as the scientists were calling for a moratorium, U.S. President George W. Bush urged the opposite. He declared the United States should increase ethanol use because of national energy security and high gas prices.
The conflicting messages Tuesday highlighted the ongoing debate over food and fuel needs.
The three senior scientists with an international research consortium pushing a biofuel moratorium said nations need to rethink programs that divert food such as corn and soybeans into fuel, given the burgeoning worldwide food crisis. The group, CGIAR, is a global network that uses science to fight hunger. It is funded by dozens of countries and private foundations.
If leading nations stopped biofuel use this year, it would lead to a price decline in corn of about 20 per cent and wheat of about 10 per cent by 2009-10, said Joachim von Braun, who heads the International Food Policy Research Institute in Washington, D.C., the policy arm of CGIAR.
Von Braun and the other scientists said work should be stepped up on the use of non-grain crops, such as switchgrass, for biofuel.
Food vs. fuel
Another scientist, not associated with the group, agreed with their call for a halt on the use of grain for fuel.
"We need to feed the stomach before we need to feed our cars," said Rattan Lal, an Ohio State University soil sciences professor who in the past has been a critic of some of CGIAR's priorities.
"We have one billion people who are food insecure. We can't afford the luxury of not taking care of them and taking care of gasoline."
In an interview after the CGIAR teleconference, von Braun said the United States and other countries have to make a hard choice between fighting high fuel prices and fighting world hunger.
"If you place a high value of food security for poor people, then the conclusion is clear that we step on the brake awhile," von Braun said. "If you place a high value on national energy security, other considerations come into play."
Energy security is what Bush emphasized in his news conference. When asked about the conflict with world hunger and the rising cost of food at home, he said the high price of gasoline would "spur more investment in ethanol as an alternative to gasoline."
"And the truth of the matter is, it's in our national interest that our farmers grow energy, as opposed to us purchasing energy from parts of the world that are unstable or may not like us," Bush said.
Still, Bush said the international food crisis "is of concern to us" and said the U.S. government earlier this month added another $200 million in food aid.
Ethanol production spurs corn prices: World Bank
A World Bank study has estimated that corn prices "rose by over 60 per cent from 2005-07, largely because of the U.S. ethanol program" combined with market forces.
Other nations, such as South Africa, have stopped or slowed the push to ethanol. But because the United States is the world's biggest producer, if it does nothing, other nations' efforts will not amount to much, von Braun said.
Von Braun said many issues are causing the food crisis, especially market forces and speculation, but that biofuel use also ranks high among the causes.
Scientists say the diversion of corn and soybeans for fuel helps force prices higher, and removes farm land from food production. Ethanol supporters say the corn used for fuels is the type only fed to livestock. However, other experts say it leads to higher livestock feed prices, thus higher food prices.
Because of this issue, legislators in Missouri are considering lifting a requirement that fuel in that state contain 10 per cent ethanol.
Just how big biofuel's effect is on food prices depends on who is talking. Bush said it's responsible for about 15 per cent of the rise in costs. U.S. Department of Agriculture spokesman Keith Williams put it closer to 20 per cent.
A soon to be released International Food Policy Research Institute analysis blames 30 per cent of the overall food price rise from 2000-2007 on biofuels. An industry-funded study put the food cost rise from biofuels at four per cent.
Matt Hartwig, a spokesman for the Renewable Fuels Association, said: "World agriculture can both feed and fuel the globe."
