Why does the food aid from the United States hurt the Haitian economy and what does it force Haitian farmers to do?

"There is a risk, definitely. And we are very aware of that," says Brooke Isham, director of the Food for Peace program at the US Agency for International Development (USAID). "And that is why we are always looking at the impact of food aid on local markets and whether it is depressing prices in local markets."

USAID, the UN World Food Program (WFP) and others monitor markets regularly. Etienne Labonde, head of WFP's program in Haiti, says, as of March, food aid did not cause major disruptions in Haiti's economy. "Maybe it's an impression, but it's not the facts at the moment," he says.

Low prices can lead Haiti's farmers to store rice rather than sell it at a loss.

Whether impression or fact, Haitian President Rene Preval raised the issue when he came to Washington last month. He said food aid was indispensible right after the earthquake. But, "If we continue to send food and water from abroad," he said, "it will compete with national production of Haiti and with Haitian trade."
