To enhance knowledge and support countries in the collection of and reporting on data, UNODC works with Member States to monitor drug cultivation, production and manufacture of cocaine, heroin, cannabis and synthetic drugs / new psychoactive substances (NPS) around the world.

Jointly with the main drug-growing countries in the world - Colombia, Peru and the Plurinational State of Bolivia for coca, Afghanistan, Mexico and Myanmar for opium and Nigeria for cannabis – the UNODC Illicit Crop Monitoring Programme (ICMP) uses GIS and geospatial analysis, satellite imagery and field surveys to monitor the extent and evolution of illicit crop cultivation and production.
