Environmental Impact of Spraying

"Guio (2003), in his study in Samaniego, Nariño (Colombia), reports that aerial fumigation of poppy crops also affect household crops and alternative crops promoted by UNODC. Intensification of fumigation has lead to an increase in complaints to the Defensoria del Pueblo regarding impacts on farmers' health, domestic animals, fishes and legal crops. Ortiz et al. (2004), in an essay about agriculture, illicit crops and the environment for the National Environmental Forum (Colombia), mentions that recent studies in Putumayo have concluded that more than 2,700 hectares of licit crops, including fruits, and more than 200,000 fish, were lost because of fumigations. These figures are for people that submitted their cases to local authorities."
