(Effect on Deforestation) "Aerial fumigation and forced eradication of coca crops is one factor in the dynamics of coca cultivation and deforestation. Several studies report that in response to coca eradication measures farmers have been deforesting new plots in more remote areas. These new plots can be in the local region or in other parts of the country, since migration and displacement of people is widespread, especially in Colombia. It has also been suggested that farmers create more scattered plots of smaller size in response to fumigation. This further fragments the forest and increases the impact on biodiversity. The relative importance of this phenomenon compared to the other drivers of coca cultivation and deforestation have not been determined."
