Uzbekistan, republic in Central Asia, bordered on the west and north by Kazakhstan, on the east by Kyrgyzstan, on the southeast by Tajikistan, and on the south by Afghanistan and Turkmenistan. The Qoraqalpogh Autonomous Republic (also known as Qoraqalpoghiston, or Karakalpakstan) occupies 37 percent of Uzbekistan’s territory in the western portion of the country. Toshkent (Tashkent), located in the northeast, is the capital city and chief industrial and cultural center. Uzbeks make up the majority of the republic’s population. In the official state language of Uzbek, the republic is called Uzbekiston Respublikasy (Republic of Uzbekistan). Uzbekistan was the Uzbek Soviet Socialist Republic (SSR) of the Union of Soviet Socialist Republics (USSR) from 1924 until 1991, when it gained its independence. In 1992 Uzbekistan was officially designated a secular and democratic republic with the ratification of its first post-Soviet constitution. However, many of the centralized controls that were characteristic of the Soviet period remain entrenched in the economic and political structures of Uzbekistan. Although the constitution guarantees a multiparty system, the republic’s president, Islam Karimov, has established an authoritarian-style regime that has been intolerant of opposition groups. Karimov has also proceeded cautiously with market-oriented economic reforms, and the government retains control over most sectors of the economy.
Uzbekistan is a landlocked country that covers an area of about 447,400 sq km (about 172,700 sq mi). Mountains dominate the landscape in the east and northeast. Several branches of the western Tien Shan and Pamirs-Alai mountain systems cross into Uzbekistan from neighboring Kyrgyzstan and Tajikistan, with some peaks reaching above 4,000 m (13,000 ft). Areas of eastern Uzbekistan are especially prone to seismic disturbances; in 1966 a strong earthquake destroyed large portions of Toshkent. To the west of the mountains, Uzbekistan is generally low in elevation. More than two-thirds of Uzbekistan’s territory is covered by desert and steppe (semiarid grassy plains). One of the largest deserts in the world, the Qyzylqum, lies in north central Uzbekistan, and extends into Kazakhstan. In northeastern Uzbekistan, southwest of Toshkent, lies the Mirzachol desert. Across west central Uzbekistan is a vast area of flat plains called the Turan Plain, while additional plains lie south and east of the Qyzylqum. The extreme western portion of the country is occupied by the Ustyurt plateau, an elevated plain with some small mountain ridges and abrupt edges.
Uzbekistan generally lies between the two largest rivers of Central Asia, the Amu Darya and Syr Darya. These two roughly parallel rivers both have their headwaters in the mountains east of Uzbekistan and follow northwesterly courses toward the Aral Sea, a saltwater lake straddling the border between Uzbekistan and Kazakhstan. Since the early 1960s the Aral Sea has shrunk to less than half its former size, and dry land has separated the remaining water into two main lakes. Uzbekistan’s largest river is the Amu Darya. This river is formed by the confluence of the Panj and Vakhsh rivers on the extreme southwestern border of Tajikistan, near the southeastern tip of Uzbekistan. The Amu Darya traverses a course generally parallel to, and at times part of, Uzbekistan’s southern borders with Afghanistan and Turkmenistan, then turns due north through Uzbekistan’s Qoraqalpogh Autonomous Republic toward the southern section of the Aral Sea. The Syr Darya is formed in the fertile Fergana (Farghona) Valley by the convergence of two rivers flowing from the east, the Naryn and Qoradaryo. The Syr Darya then flows westward through this valley and northern Tajikistan, turns north to cut through Uzbekistan, and enters Kazakhstan, eventually reaching the northern section of the Aral Sea. Another important river is the Zeravshan, which flows westward from the mountains of Tajikistan through east central Uzbekistan. Before it began to be tapped for irrigation, the Zeravshan was the Amu Darya’s largest tributary; now it dissipates in the Qyzylqum desert near the city of Bukhara (Bukhoro). Uzbekistan has thousands of small streams that expire in the desert, many having been emptied by irrigation. Extensive canal systems, such as the Amu-Bukhara canal and many others built during the Soviet period, have greatly altered water-flow patterns. Artificial lakes and reservoirs have been created, many of which are fed by irrigation runoff. The largest freshwater lake is Lake Aydarkul, in northeastern Uzbekistan.
Uzbekistan’s mixed topography provides divergent wildlife habitats. In the steppes the endangered saiga antelope can be found, as well as roe deer, wolves, foxes, and badgers. The desert monitor, a large lizard that can reach lengths of 1.6 m (5 ft), thrives in the Qyzylqum desert, along with a type of gazelle and a number of rodent species. The river deltas are home to wild boars, jackals, and deer, with a variety of pink deer living in the Amu Darya delta. The Turan (or Caspian) tiger is now extinct: The last one was killed in the Amu Darya delta in 1972. The endangered snow leopard, which has long been hunted illegally for its prized fur, lives in the eastern mountains. The mountains also are home to several types of mountain goat, including the Alpine ibex (characterized by enormous, back-curving horns), as well as lynx, wild boars, wolves, and brown bears. A number of bird species are native to the steppes, including ring-necked pheasants, black grouse, partridges, falcons, and hawks. Eagles and lammergeyers (a type of vulture) nest in the mountainous regions, preying on marmots and mouse hares. Ducks, geese, and other birds migrate through the marshes of the Ustyurt plateau. Plant life is equally diverse. Drought-resistant grasses and low shrubs cover the steppes, except in areas that have been cleared for crop cultivation. Ancient walnut-tree forests are located in the lower mountains, whereas spruce, larch, and juniper thrive in the higher elevations. Elm and poplar trees grow along riverbanks, along with dense stands of brush called tugai.
