The second issue of our series is dedicated to the controversial topic of Colombia’s aerial fumigation of coca and opium poppy fields.

Despite 2006 witnessing the most intensive use of fumigation in the country’s history, some 157,200 hectares of cultivation areas were detected, 13,200 hectares more than in 2005. Is the fumigation strategy failing?

For 37 years Colombia has been spraying chemicals to combat illicit crops, particularly coca. These massive eradication programmes became part of the US-backed 'War on Drugs'. The fumigations are controversial for their proven inefficacy to reduce supply and demand for the use of herbicides such as glyphosate.
