PORT-AU-PRINCE, HAITI: Joseph Francois has a cupboard filled with dishes but rarely takes them out, even at the best of times.

The food riots that gripped Haiti this week made scrounging something to eat even harder. A frenzy of violence and gunfire kept the unemployed father of two from venturing out to beg for three days.

By Thursday afternoon, after the bandits and looters retreated, Francois was able to spend 67 cents on a small bowl of rice to be shared by his two young children. There was nothing left for himself or his girlfriend.

''Most of the time we get up and have nothing to eat. We just pray for the sun to go down so we can go to sleep,'' said Francois, frayed jeans hanging loosely on his scrawny frame beneath a Jimi Hendrix T-shirt.

Hunger has long been a fact of life in Haiti's overcrowded slums, but soaring food prices have made the struggles of Haiti's poor unbearable. Francois buys rice from a woman whose prices have more than doubled over the past six months, from 27 cents to 67 cents for a small bowl. Other staples have doubled as well. The violence has only made things worse.

''The country was upside down. I couldn't go out, so the kids had no food,'' said Francois, who lives with 3-year-old Bechina, 4-year-old Charlie and his girlfriend, Betty Joseph, in an abandoned one-room schoolhouse in a slum called ''Ideal City.''

The dark cement-block structure has been home since their own house burned down in December. The only light comes from a fluorescent bulb rigged to an electrical wire outside; a television set plays dubbed American movies. No food could be seen, and the metal pot used for cooking on a charcoal burner in the alley outside was empty.

Globally, food prices have risen 40 percent since mid-2007. Haiti, where most people live on less than $2 a day, is particularly affected because it imports nearly all of its food, including more than 80 percent of its rice.

Much of Haiti's once-productive farmland has been abandoned as farmers struggle to grow crops in soil decimated by erosion, deforestation, flooding and tropical storms. To make a profit, the farms that remain often price their crops sharply higher than imported American products, which benefit from generous U.S. government subsidies.

Some aid was on its way Friday. Brazil, which has about 1,200 peacekeepers serving in Haiti, sent an air force plane with 14 tons of food, including beans, sugar and cooking oil. France pledged food and other aid worth $1.6 million. The U.N. World Food Program, which had collected only 15 percent of its Haiti budget before the riots, appealed for donations to meet its $96 million goal.

But the U.N. Food and Agriculture Organization said Friday that high food prices in the developing world are unlikely to subside anytime soon as price speculation and market failures counteract increases in food production.

This spells disaster in a nation where the World Bank says per capita income is just $480 a year.

Francois, gaunt and balding at 32, doesn't even have that much. Mostly, he depends on handouts from neighbors and friends. He begs in the street. If all else fails, he hunts for scraps in the garbage piles at the nearby La Saline market.
