From the Miami Herald, July 30:

Colombia announced in July it will favor manual eradication of coca crops over the current system that focuses heavily on aerial fumigation. The spray program has been the source of endless legal, social and diplomatic conflicts because of the controversy over the health and environmental effects of the chemicals. The latest estimates of coca acreage -- showing little drop -- have fueled doubts on the effectiveness of the spray program. And the new Democratic majority in the U.S. Congress is viewed as less friendly toward spraying.

"Instead of uniting Colombians around the idea of eradicating drugs, [aerial spraying] causes complaints and provokes reactions against eradication," President Alvaro Uribe said in a July 20 speech in which he announced the shift. He said spraying would remain only a "marginal" part of the counter-drug strategy.

Many longtime critics of the fumigation policy applauded the decision, including the government in neighboring Ecuador, for whom aerial spraying along the border had become a major
diplomatic issue with Colombia.

Coca growers often replant crops damaged by aerial fumigations, and plants often grow back stronger after fumigation. They also have learned to coat leaves with a sugary substance to protect them against the herbicide glyphosate. Manual eradicators do a more thorough job by chopping off bigger plants, uprooting smaller ones and destroying plant nurseries that otherwise quickly would replace plants killed by the aerial spraying.

The U.S. government has limited its contributions to previous manual eradication efforts in Colombia, supplying only logistical support for the programs such as aircraft fuel. But Colombian, U.S. State Department and U.S. congressional officials are looking into a major overhaul of Plan Colombia rules that would allow more U.S. assistance for manual eradication efforts, several persons familiar with the conversations say.

The Senate version of the Foreign Appropriations bill earmarks $10 million of the military aid specifically for operations to provide security for manual eradication, and stipulates that funds for aerial fumigation could only be used in specific areas where the State Department has certified that manual eradication is not feasible.

This year, Defense Minister Santos said, the government expects to manually eradicate 173,000 acres, and spray 321,000. But Victoria Restrepo, head of the government's manual eradication program, said she cringes every time she hears Santos announce the target. She told The Miami Herald that with the resources she now has, she barely will make her agency's original target for the year of 123,500 acres. So far this year, eradicators have cleared just under 60,000 acres.

Analysts warn, however, that any eradication efforts not accompanied by comprehensive efforts to give farmers a legal alternative to coca growing are doomed to fail. "The farmers have to be taken into account. Otherwise, they will just wait for the eradicators to leave, and they will replant," said Astrid Puente of the environmental group AIDA, which monitors fumigation in Colombia.
