Olá Pessoal, aqui eh um artigo de nytimes sobre do futuro de

'ethanol', qual o Brasil  esta tentando fazer muito. Creara mais fome?

SIOUX CENTER, Iowa, Jan. 11 - Early every winter here, farmers make

their best guesses about how much food the world will demand in the

coming year, and then decide how many acres of corn to plant, and how

many of soybeans.

But this year is different. Now it is not just the demand for food

that is driving the decision, it is also the demand for ethanol, the

fuel that is made from corn.

Some states are requiring that ethanol be blended in small amounts

with gasoline to comply with anti-pollution laws. High oil prices are

dragging corn prices up with them, as the value of ethanol is pushed

up by the value of the fuel it replaces.

"We're leaning more toward corn," said Garold Den Herder, a farmer who

cultivates 2,400 acres in a combination of corn and soybeans and is on

the board of directors of the Siouxland Energy and Livestock

Cooperative, which opened an ethanol plant here in late 2001. Last

year a bushel was selling for about $2 here, but near the plant it was

about 10 cents higher.

Farmers expect it to go higher soon if oil prices stay high. Ethanol

was up to $1.75 a gallon, last year, from just over $1 the year

before.

The rising corn prices may be good news for farmers, but they are

worrying some food planners.

"We're putting the supermarket in competition with the corner filling

station for the output of the farm," said Lester R. Brown, an

agriculture expert in Washington, D.C., and president of the Earth

Policy Institute. Farms cannot feed all the world's people and its

motor vehicles as well, Mr. Brown said, and the result is that more

people will go hungry.

Others say that the price of goods that have corn as an ingredient,

including foods like potato chips or Danish pastries, will rise.

But Robert C. Brown, a professor of mechanical engineering at Iowa

State University and a specialist in agricultural engineering, said

the use of corn for nonfood purposes sounded harsher than it was. "The

impression is that we're taking food out of the mouths of babes,"

Professor Brown said. In fact, corn grown in Iowa is used mostly to

feed farm animals or make corn syrup for processed foods.

And Bernie Punt, the general manager of the Siouxland plant, said,

"It's not as big a loss as what it seems like," pointing out that the

corn remnants that come out of the other end of the plant were used

for animal feed.

A global shift to farm-based fuel could reduce the need for oil and

slow climate change. But Lester Brown is not alone in worrying about

the effect on world hunger. For 20 years, the International Food

Policy Research Institute, a nonprofit group in Washington, has

maintained a computer model to predict food supplies, based on

population changes, farm policies and other factors.

Until now, the institute's analysis had included the price of oil and

natural gas only as a factor in production costs, including the price

of making fertilizer, running a tractor or hauling food to markets.

But last year, after Joachim von Braun, the director of the institute,

went to Brazil and India, both of which make vehicle fuel from plants,

he told his economists to change the model, taking into account the

demand for energy from farm products.

Even a small shift could have big effects, Mr. von Braun said, because

"the mouth of your car is a monster compared to your family's stomach

needs."

"I do not just expect somewhat higher food prices, but new instability

as well," he said in an interview. "In the future, instability of

energy prices will be translated into instability in food prices."

Gustavo Best, the energy coordinator at the United Nations Food and

Agriculture Organization, said growing crops for energy could provide

new opportunities for small farmers around the world and finance the

development of roads and other valuable infrastructure in poor rural

areas.

But, Mr. Best added, "definitely there is a danger that the

competition can hit food security and food availability."

Some experts scoff at the idea of corn shortages, but others say it is

possible. Wendy K. Wintersteen, the dean of the College of Agriculture

at Iowa State University, said that possibly as early as this summer,

"we will have areas of the state we would call corn deficient,"

because there will not be enough for livestock feed - the biggest use

of corn here - and ethanol plants.

"It's a hard thing to imagine in Iowa," Ms. Wintersteen said.

Eventually, experts say, American corn exports could fall.

Nationwide, the use of corn for energy could result in farmers'

planting more of it and less wheat and cotton, said Keith J. Collins,

chief economist of the Department of Agriculture. But the United

States is paying farmers not to grow crops on 35 million acres, to

prop up the value of corn, he said, and much of that land could come

back into production.
