The United Nations says the amount of land used to cultivate coca, the raw material in cocaine, has increased in Peru.
In an annual report, the U.N. Office on Drugs and Crime notes a seven percent expansion of the area devoted to the coca crop last year.
The agency estimates that cocaine production in Peru had increased eight percent from 2005. It said the area under cultivation rose to 51,400 hectares last year, from 48,000 the year before.
In April, Peruvian President Alan Garcia said his country should use its military aircraft to attack coca processing facilities and drug traffickers' jungle airstrips.
The United Nations says Peru produces about 30 percent of the world's cocaine - second only to Colombia.
