Summary: 463Ambio Vol. 32 No 7, Nov. 2003 © Royal Swedish Academy of Sciences 2003
http://www.ambio.kva.se
Chemical control of desert locust (DL) is carried out over
large areas of land, covering a range of different land-
scapes and ecosystems. There are no real restrictions
for spraying in or close to environmentally sensitive
areas and awareness of sensitivity is not always obvious
to the people involved in control. However, concern about
environmental issues in connection with DL control is
growing and clear guidelines are needed. The objectives
were: to identify and delineate areas particularly sensitive
to pesticide contamination in northeastern Africa, e.g.
protected areas, wetlands, populated places, oases, and
areas with concentrations of migratory birds. These
areas were matched with actual DL control during
1986-1998. The conclusion is that chemical control
occurred in environmentally sensitive areas especially
wetlands, e.g. temporary waters and mangroves; close
to human settlements; and, to some extent, in or near
protected areas and areas with numerous migratory birds.
