Total Worldwide Coca Cultivation And Production

"Following a massive upward trend over the period 2013–2017, during which the area under coca bush cultivation at the global level more than doubled, the size of that area seems to have stabilized and remained, in 2018, at a historically high level. According to preliminary estimates, the global area under coca cultivation may have even declined marginally in 2018 compared with a year earlier due to declines reported by Colombia (1.2 per cent) and Bolivia (Plurinational State of) (5.7 per cent), while comparable estimates for Peru are not available.

"Even though final global estimates for 2018 are not yet available, preliminary results indicate that Colombia remains the country where most coca leaf is produced. In 2017, the latest year for which comparable estimates are available, Colombia accounted for 70 per cent of the global area under coca cultivation, Peru for 20 per cent and Bolivia (Plurinational State of) for 10 per cent.15

"On the basis of preliminary estimates, the global manufacture of cocaine hydrochloride may have reached its highest level ever in 2018, at 1,723 tons (expressed at 100 per cent purity). While cocaine manufacture is estimated to have almost doubled between 2014 and 2018, growth in manufacture has slowed over the years, pointing to a potential stabilization in 2018. Global cocaine manufacture increased by 37 per cent between 2015 and 2016, by 23 per cent between 2016 and 2017, and by 4.6 per cent between 2017 and 2018."
