Ricardo Soberon, the reformist head of DEVIDA, the Peruvian drug agency, has been fired and replaced, the Peruvian government announced Tuesday. Soberon made waves last August when he implemented a temporary ban on forced eradication of coca plants, taking the US Embassy by surprise, but that was soon reversed on the orders of his boss, Interior Minister Oscar Valdes.

[image:1 align:right caption:true]Relations between Soberon and Valdes never warmed, and he "resigned" on Tuesday after just five months in office. Soberon also found himself increasingly at odds with President Ollanta Humala, who had campaigned on a pledge to not aggressively pursue eradication, but who has shifted to the right on this and other issues since taking power.

Soberon had taken that same message to coca growers, with whom he had forged relationships after years of work in the field. His departure could mean an uptick in conflict in the already contentious relationship between coca grower unions and the government.

"Soberon's exit was a matter of time," Peruvian drug policy expert Jaime Antezana told the Washington Post. "There was no chance that Oscar Valdes would keep him in the job."

Soberon had been working on a five-year national drug strategy that would have called for vigorous pursuit of cocaine traffickers and money launderers and interdiction of incoming precursor chemicals and outgoing cocaine, but de-emphasized punishing the peasants who grow coca outside the government coca monopoly, ENACO. That strategy was never approved.

Peru is now arguably the world's largest producer of cocaine, having surpassed Colombia despite the latter country's having more acreage of coca planted, according to US officials. Peru's coca fields are higher-yielding because they are more mature, and the country had the potential to produce 325 metric tons of cocaine last year, compared to 270 tons in Colombia.

Peru eradicated about 15% of the crop last year, but at the political price of alienating thousands of coca growing farm families. Now, it appears ready to deepen that divide.
