An unwelcome resurgence

摘要

THE hills surrounding Sinai, a village in south-west Colombia, are blanketed in a green patchwork, ranging from the bright chartreuse of coca-plant seedlings to a darker clover colour that indicates the leaves are ripe for picking and processing into cocaine. It is areas like this that have helped to boost Colombia's estimated cocaine output 37% since 2015 to an all-time high of 710 tonnes in 2016, according to America's government. Some 188,000 hectares of land is now planted with coca, up from a low of 78,000 in 2012.
