A United Nations survey says Peru has replaced Colombia as the world's top producer of coca, the plant used to make cocaine.
The U.N. Office on Drugs and Crime says coca plants covered 60,400 hectares in Peru last year, 20 percent more than in Colombia.
Total cultivation in Peru dropped about 3 percent last year, but eradication efforts in Colombia helped slash that nation's total area of coca-growing fields by 25 percent.
It is not clear which country now produces more cocaine, because there are no recent figures for Peru.
Peruvian President Ollanta Humala, a retired military officer who assumed office two years ago, has intensified eradication and cracked down on rebels who control drug trafficking.
