As heroin exports rise and battlefield successes become rarer, the US intends to start doing what they have been doing in Colombia for years: Carpet bombing the drug crop fields with Monsanto-made glyphosate, Roundup Ultra. What could seem like a win-win strategy has many darker sides to it though.
"Aerial spraying is a bad idea, first because the Afghans have to do the eradication if it is to avoid a backlash from farmers and play into the hands of Taliban propaganda. Western aircraft spraying Afghan fields doesn't look like the government is responsible. There are also bound to be charges that people's health or animals have been affected and there is sure to be collateral damage to legal crops." - European counter-narcotics official in the Telegraph article

So, how has the Chemical War on Drugs fared in Colombia? Well, most biologically interesting is the appearance of a glyphosate resistant - "Roundup Ready" - variety of the coca bush (source: Wired, Wikipedia)! And yes, there has been reports of health problems in farmer populations and damage to legal crops. One lengthy, thorough and critical look at Plan Colombia is CorpWatch.org's Toxic Drift: Monsanto and the Drug War in Colombia (2001). From that article:
"The twelve indigenous peoples have been suffering under this plague as if it were a government decree to exterminate our culture and our very survival. Our legal crops -- our only sustenance -- manioc, banana, palms, sugar cane, and corn have been fumigated. Our sources of water, creeks, rivers, lakes, have been poisoned, killing our fish and other living things. Today, hunger is our daily bread. In the name of the Amazonian Indigenous people I ask that the fumigations be immediately suspended." - José Francisco Tenorio.
Of course, there is also a lot of information on Wikipedia: see entries Plan Colombia and Coca eradication.
A short, short summary is billions of tax payer's money have been spent, wide stretches of Colombian biosphere scorched, coca production is up, cocaine prices are down and abuse on the rise, the civil war is still raging and the Monsanto stock price is up and climbing. Of course, each of these results have been influenced by numerous factors, not just Roundup. But personally I fail to see the big success worth copying.
