Geography of Uzbekistan Kazakhstan, also yielded about 60% of the total volume of Central Asia's emissions of harmful substances into the atmosphere. Because automobiles are relatively scarce, automotive exhaust is a problem only in Tashkent and Farghona. The reduction of water in Uzbekistan has resulted in soil degradation, and the spread of the salt from the evaporated Aral Sea has contaminated the surrounding soil. The soil has lost much of its water due to the increased surface irrigation. The irrigation of farmlands with water from the Aral Sea has resulted in increased salinization of the soil, causing the farmland to be less productive
Kyrgyzstan–Uzbekistan border Kyrgyzstan–Uzbekistan border The Kyrgyzstan-Uzbekistan border is 1,314km (816m) and runs from the tripoint with Kazakhstan to the tripoint with Tajikistan. It is Kyrgyzstan’s longest external boundary. The border starts in the north at the tripoint with Kazakhstan and then creates a ‘finger’ of Uzbek territory wedged between Kazakhstan and Kyrgyzstan; the border traverses the Pskem Mountains, with much of this area being taken up by a series of national parks (Ugam-Chatkal National Park in Uzbekistan and Besh-Aral State Nature Reserve in Kyrgyzstan). The boundary then proceeds in a roughly south-eastwards direction, traversing the Chatkal Range and the Qurama Mountains before
