Children dying in Haiti, victims of food crisis and tropical storms

The World Food Program has sent more than 30 tons of food aid — enough to feed 5,800 people for two weeks — into the remote southeastern region since September, and other groups funded by the U.S. Agency for International Development have sent food as well, she said.

But the steep, narrow paths and poor visibility make it difficult to deliver the food to the mountain communities where hunger is worsening. In one case, a WFP truck flipped over while struggling up a hill and slid into a ravine, killing an aid worker.

"There is always a bottleneck. The same situation that the people are facing is the same situation we're also facing," Kaulard told The Associated Press Thursday.

The mountain villages have long suffered from chronic hunger, growing only enough staples to feed themselves less than seven months out of the year, she said.

But families normally have enough to last through December. This year, Haiti's agriculture ministry estimates 60 percent of the harvest was lost in the storms nationwide. Land quality is already poor and farmers lost seeds for next year when the storms hit, Kaulard said.

Effects of the storms vary widely from village to village and even family to family. In some places, food supplies seem intact. In others, Doctors Without Borders has found rates of severe malnutrition as high as 5 percent.
