Desertification in the Caspian Sea region
Contrasting rainfall trends have been observed in the north and south. Whereas rainfall over Russia has increased over the last century, already dry areas such as the coasts of Turkmenistan and Iran have become even drier. Dust storms pick up large amounts of salt and dust as they pass over the Kara-Kum desert and the Caspian Sea shore, depositing it in the Volga valley where it impairs the fertility of arable land.
