In August, the locust infestations declined in all countries as a result of the intense and large-scale control operations previously carried out mainly until the end of July and of the progressive disappearance of the remaining locust populations. Nevertheless, the situation was still worrying in Georgia and Russia, where a total of almost 46 000 hectares (ha) were treated. Control operations were also carried out in Kyrgyzstan and Armenia. Overall, control operations were carried out on a bit more than 50 000 ha in Caucasus and Central Asia (CCA) in August, an almost twentyfold decrease as compared to the previous month.
RECENT TRENDS (from 2006)
Over the past five years, an important trend in the five Central Asian countries is the increase of locust infested areas: they went up from 2,5 million ha in 2006 to 3.9 million ha in 2011, thus representing an increase of 54%, after a peak reaching 4,6 million ha in 2010. Similar trends exist in the adjacent countries, i.e. Afghanistan and the Russian Federation, as well as in Azerbaijan.
The below tables present the surveyed, infested and treated areas (in hectares) from 2005 to 2013 in Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan), Caucasus (Armenia, Azerbaijan and Georgia) and CCA adjacent areas (Afghanistan and Russian Federation).
