Simulation of the Glyphosate Aerial Spray Drift at the Ecuador-Colombia border


Glyphosate is one of the herbicides used by the Colombian government to spray coca fields close to the Ecuadorian border. The sprays have been taking place for a number of years and have been more frequent since 2000 (when \"Plan Colombia\" started).

The spray drifts into Ecuadorian territory have become a big issue for people living close to the border. Their negative impact on health and agriculture have been observed and confirmed by intensive studies (e.g. [Avila et. al. 2007]). Hence, in 2005 Ecuador and Colombia signed an agreement to stop the sprays along a 10 km stripe at the border. However, measurements on Ecuadorian territory indicate that significant amounts of Glyphosate spray have still drifted into Ecuador.
The main goals of this project are to develop a (reverse) numerical simulation of the spray drift, analyze whether the 10 km stripe is enough to protect Ecuadorian territory and assess whether the agreement has been respected.
