Project
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 range is
enough to protect Ecuadorian territory and assess whether the
agreement has been respected.
