The US government has determined that Bolivia now has fewer coca plantations but it is producing more cocaine because traffickers are using a more "efficient" process known as the "Colombian method," according to an interview with a diplomat in La Paz daily Pagina Siete. Said John Creamer, outgoing charge d'affaires at the US diplomatic mission in La Paz: "That is the paradox in Bolivia. There are fewer coca plantations in the past three years, but there's more production of cocaine." Creamer said that using the new process, producers "can obtain more cocaine with lesser quantities of coca leaves." He also warned of the "resowing" of eradicated coca fields. The Bolivian government boasts that it reduced coca leaf production for three consecutive years from 2009 to 2011, but according to UN figures overall coca production increased from 25,400 hectares in 2006 when Evo Morales took power to 31,000 hectares in 2010 (the last year for which the UN has data). Bolivian law allows the legal cultivation of just 12,000 hectares of coca for traditional purposes.
