Several severe droughts have affected various parts of the region in recent years. They seem to confirm scientific models, which, in addition to higher mean temperatures, generally predict more extreme weather events. Droughts affect both crop production and the health of livestock. But the availability of freshwater, on which many sectors of the economy – and human well-being – depend, is also linked to more remote climatic processes. If glaciers in the Caucasus and Elburz mountains recede and the periods of snow cover become shorter, as has been the case in recent years, less water will be available for use in irrigation and homes.
