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.
The distribution of land and its unjust use are the major causes of violence in Colombia. For this reason land issues are the starting point of current peace talks between the Santos government and the FARC guerrillas
The consequence of associating the 'war on drugs' with the 'war on terrorism' is that the failure of the former could end with the failure of the latter. The predominant military approach to 'narcoterrorism' fails to recognise the complex factors underlying both the drug problem and the violence; it assumes that the drug problem can be solved by force and that the armed conflict can be resolved by intensifying the conflict - that is, more war on war; and it has facilitated the consolidation of conventional drug-trafficking structures.
While escalating civil conflict in Colombia is attracting increasing international interest and concern, the complex relationships between drug trafficking, political violence, and the many actors involved in the social conflict in Colombia are often absent from the debate.
