Aral Sea reduction between 1973 and 2000,satellite images. North is at top. THe middle puicture dates from 1989. Since the 1960s the Aral Sea,on the borders of Uzbekistan (south west) and Kazakhstan (north east),has lost more than half of its volume. This is due to overuse of the feeder rivers (the Syr Darya and Amu Darya) in irrigation of cotton and paddy fields. The consequent receding waterline and increased salination has destroyed the region's fishing industry. Exposed areas of salt are blown by winds into the surrounding area,reducing crop yields | |
