The hair on broomstick-thin children has turned patchy and orangish, their stomachs have ballooned to the size of their heads and many look half their age - the tell-tale signs of malnutrition.

Mabriole town official Geneus Lissage fears that death is imminent for these children if Haitian authorities and humanitarian workers don't do more to stem the hunger problems.

"They will be counting bodies," Lissage said, "because malnutrition is ravaging children, youngsters and babies."

Three years after an earthquake killed hundreds of thousands and the US promised that Haiti would "build back better," hunger is worse than ever. Despite billions of dollars from around the world pledged toward rebuilding efforts, the country's food problems underscore just how vulnerable its 10 million people remain.

In 1997 some 1.2 million Haitians didn't have enough food to eat. A decade later the number had more than doubled. Today, that figure is 6.7 million, or a staggering 67 percent of the population that goes without food some days, can't afford a balanced diet or has limited access to food, according to surveys by the government's National Coordination of Food Security. As many as 1.5 million of those face malnutrition and other hunger-related problems.

"This is scandalous. This should not be," said Claude Beauboeuf, a Haitian economist and sometime consultant to relief groups. "But I'm not surprised, because some of the people in the slums eat once every two days."

Much of the crisis stems from too little rain, and then too much. A drought last year destroyed key crops, followed by flooding caused by the outer bands of Tropical Storm Isaac and Hurricane Sandy.

Haiti has had similarly destructive storms over the past decade, and scientists say they expect to see more as global climate change provokes severe weather systems.

Klaus Eberwein, general director of the government's Economic and Social Assistance Fund, said: "We are really trying our best. It's not like we're sitting here and not working on it. We have limited resources."

He attributed Haiti's current hunger woes to "decades of bad political decisions" and, more recently, to last year's storms and drought. "Hunger is not new in Haiti," Eberwein said. "You can't address the hunger situation in one year, two years."

Political decisions already had hurt the ability of Haitian farmers to feed the country. One example: Prodded by the administration of U.S. President Bill Clinton, Haiti cut tariffs on imported U.S. rice, driving many locals out of the market.

Eighty percent of Haiti's rice - and half of all its food - is imported now. Three decades ago, Haiti imported only 19 percent of its food and produced enough rice to export. Factories built in the capital at the same time did little to help: They led farmers to abandon their fields in the countryside in hope of higher wages.

At the same time, Haiti has lost almost all of its forest cover as desperately poor Haitians chop down trees to make charcoal. The widespread deforestation does little to contain heavy rainfall or yield crop-producing soil.

With so much depending on imports, meals are becoming less affordable as the value of Haiti's currency depreciates against the U.S. dollar. Haiti's minimum wage is 200 gourdes a day. Late last year, that salary was equivalent to about $4.75; today it's about $4.54 - a small difference that makes a big strain on the Haitian budget.

Shortly after taking office, President Michel Martelly launched a nationwide program led by his wife, Sophia, called Aba Grangou, Creole for "end hunger." Financed with $30 million from Venezuela's PetroCaribe fund, the program aims to halve the number of people who are hungry in Haiti by 2016 and eradicate hunger and malnutrition altogether by 2025. Some 2.2 million children are supposed to take part in a school food program financed by the fund.

Eberwein, whose government agency oversees Aba Grangou, said 60,000 mothers have received cash transfers for keeping their children in school. A half million food kits were distributed after Hurricane Sandy, along with 45,000 seed kits to replenish damaged crops, he said. Mid- to long-term solutions require creating jobs.

But the villagers in the Belle Anse area say they've seen scant evidence of the program, as if officials have forgotten the deaths in 2008 of at least 26 severely malnourished children in this very region. That same year, the government collapsed after soaring food prices triggered riots.

USAID has allocated nearly $20 million to international aid groups to focus on food problems since Hurricane Sandy, but villagers in southern Haiti said they have seen little evidence of that.

Despite the discrepancy, one public health expert said there's sufficient proof that at least some of the aid is reaching the population. Were it not, Richard Garfield said, Haiti would see mass migration and unrest.

Haiti in general and the mountain villages in particular have long suffered from chronic hunger. Child malnutrition rates have been high for years. The United Nations' World Food Program reports that nearly a quarter of Haiti's children suffer from malnutrition, though the figure is higher in places such as Guatemala and the Sahel region in Africa.
