Central Asia


Central Asia is a region of Asia consisting of Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan, and most of Kazakhstan. The countries as a group are also colloquially referred to as the "-stans" as all have names ending with the Persian suffix "-stan" in both respective native languages and most other languages. The region is bounded by the Caspian Sea to the southwest, European Russia to the northwest, China and Mongolia to the east, Afghanistan and Iran to the south, and Siberia to the north. Together, the five Central Asian countries have a total population of around million.
In the pre-Islamic and early Islamic eras Central Asia was inhabited predominantly by Iranian peoples, populated by Eastern Iranian-speaking Bactrians, Sogdians, Chorasmians, and the semi-nomadic Scythians and Dahae. As the result of Turkic migration, Central Asia also became the homeland for the Kazakhs, Kyrgyzs, Tatars, Turkmens, Uyghurs, and Uzbeks; Turkic languages largely replaced the Iranian languages spoken in the area, with the exception of Tajikistan and areas where Tajik is spoken.
The Silk Road trade routes crossed through Central Asia, leading to the rise of prosperous trade cities. acting as a crossroads for the movement of people, goods, and ideas between Europe and the Far East. Most countries in Central Asia are still integral to parts of the world economy.
From the mid-19th century until near the end of the 20th century, Central Asia was incorporated into the Russian Empire, and later the Soviet Union, which led to Russians and other Slavs colonising the area. Modern-day Central Asia is home to a large population of descendants of European settlers, who mostly live in Kazakhstan: 7 million Russians, 500,000 Ukrainians, and about 170,000 Germans. During the Stalinist period, the forced deportation of Koreans in the Soviet Union resulted in a population of over 300,000 Koreans in the region.

Definitions

One of the first geographers to mention Central Asia as a distinct region of the world was Alexander von Humboldt. The borders of Central Asia are subject to multiple definitions. Historically, political geography and culture have been two significant parameters widely used in scholarly definitions of Central Asia. Humboldt's definition comprised every country between 5° North and 5° South of the latitude 44.5°N. Humboldt mentions some geographic features of this region, which include the Caspian Sea in the west, the Altai mountains in the north and the Hindu Kush and Pamir mountains in the South. He did not give an eastern border for the region. His legacy is still seen: Humboldt University of Berlin, named after him, offers a course in Central Asian studies. The Russian geographer Nikolaĭ Khanykov questioned the latitudinal definition of Central Asia and preferred a physical one of all countries located in the region landlocked from water, including Afghanistan, Khorasan, Kyrgyzstan, Tajikistan, Turkmenistan, East Turkestan, Mongolia, and Uzbekistan.
Russian culture has two distinct terms: Средняя Азия and Центральная Азия. The latter definition includes Afghanistan and 'East Turkestan'.
The most limited definition was the official one of the Soviet Union, which defined Middle Asia as consisting solely of Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan, omitting Kazakhstan. Soon after the dissolution of the Soviet Union in 1991, the leaders of the four former Soviet Central Asian Republics met in Tashkent and declared that the definition of Central Asia should include Kazakhstan as well as the original four included by the Soviets. Since then, this has become the most common definition of Central Asia.
In 1978, UNESCO defined the region as "Afghanistan, north-eastern Iran, Pakistan, northern India, western China, Mongolia and the Soviet Central Asian Republics".
An alternative method is to define the region based on ethnicity, and in particular, areas populated by Eastern Turkic, Eastern Iranian, or Mongolian peoples. These areas include Xinjiang Uyghur Autonomous Region, the Turkic regions of southern Siberia, the five republics, and Afghan Turkestan. Afghanistan as a whole, the northern and western areas of Pakistan and the Kashmir Valley of India may also be included. The Tibetans and Ladakhis are also included. Most of the mentioned peoples are considered the "indigenous" peoples of the vast region. Central Asia is sometimes referred to as Turkestan.

Geography

Central Asia is a region of varied geography, including high passes and mountains, vast deserts, and especially treeless, grassy steppes. The vast steppe areas of Central Asia are considered together with the steppes of Eastern Europe as a homogeneous geographical zone known as the Eurasian Steppe.
Much of the land of Central Asia is too dry or too rugged for farming. The Gobi Desert extends from the foot of the Pamirs, 77°E, to the Great Khingan Mountains, 116°–118°E.

Central Asia has the following geographic extremes:
  • The world's northernmost desert, at Buurug Deliin Els, Mongolia, 50°18'N.
  • The Northern Hemisphere's southernmost permafrost, at Erdenetsogt sum, Mongolia, 46°17'N.
  • The world's shortest distance between non-frozen desert and permafrost:.
  • The Eurasian pole of inaccessibility.
A majority of the people earn a living by herding livestock. Industrial activity centers in the region's cities.
Major rivers of the region include the Amu Darya, the Syr Darya, Irtysh, the Hari River and the Murghab River. Major bodies of water include the Aral Sea and Lake Balkhash, both of which are part of the huge west-central Asian endorheic basin that also includes the Caspian Sea.
Both of these bodies of water have shrunk significantly in recent decades due to the diversion of water from rivers that feed them for irrigation and industrial purposes. Water is an extremely valuable resource in arid Central Asia and can lead to rather significant international disputes.

Historical regions

Central Asia is bounded on the north by the forests of Siberia. The northern half of Central Asia is the middle part of the Eurasian steppe. Westward the Kazakh steppe merges into the Russian-Ukrainian steppe and eastward into the steppes and deserts of Dzungaria and Mongolia. Southward the land becomes increasingly dry and the nomadic population increasingly thin. The south supports areas of dense population and cities wherever irrigation is possible. The main irrigated areas are along the eastern mountains, along the Oxus and Jaxartes Rivers and along the north flank of the Kopet Dagh near the Persian border. East of the Kopet Dagh is the important oasis of Merv and then a few places in Afghanistan like Herat and Balkh. Two projections of the Tian Shan create three "bays" along the eastern mountains. The largest, in the north, is eastern Kazakhstan, traditionally called Jetysu or Semirechye which contains Lake Balkhash. In the center is the small but densely populated Ferghana valley. In the south is Bactria, later called Tocharistan, which is bounded on the south by the Hindu Kush mountains of Afghanistan. The Syr Darya rises in the Ferghana valley and the Amu Darya rises in Bactria. Both flow northwest into the Aral Sea. Where the Oxus meets the Aral Sea it forms a large delta called Khwarazm and later the Khanate of Khiva. North of the Oxus is the less-famous but equally important Zarafshan River which waters the great trading cities of Bokhara and Samarkand. The other great commercial city was Tashkent northwest of the mouth of the Ferghana valley. The land immediately north of the Oxus was called Transoxiana and also Sogdia, especially when referring to the Sogdian merchants who dominated the silk road trade.
To the east, Dzungaria and the Tarim Basin were united into the Manchu-Chinese province of Xinjiang about 1759. Caravans from China usually went along the north or south side of the Tarim basin and joined at Kashgar before crossing the mountains northwest to Ferghana or southwest to Bactria. A minor branch of the silk road went north of the Tian Shan through Dzungaria and Zhetysu before turning southwest near Tashkent. Nomadic migrations usually moved from Mongolia through Dzungaria before turning southwest to conquer the settled lands or continuing west toward Europe.
The Kyzyl Kum Desert or semi-desert is between the Oxus and Jaxartes, and the Karakum Desert is between the Oxus and Kopet Dagh in Turkmenistan. Khorasan meant approximately northeast Persia and northern Afghanistan. Margiana was the region around Merv. The Ustyurt Plateau is between the Aral and Caspian Seas.
To the southwest, across the Kopet Dagh, lies Persia. From here Persian and Islamic civilisation penetrated Central Asia and dominated its high culture until the Russian conquest. In the southeast is the route to India. In early times Buddhism spread north and throughout much of history warrior kings and tribes would move southeast to establish their rule in northern India. Most nomadic conquerors entered from the northeast. After 1800 western civilisation in its Russian and Soviet form penetrated from the northwest.
;Names of historical regions
Because Central Asia is landlocked and not buffered by a large body of water, temperature fluctuations are often severe, excluding the hot, sunny summer months. In most areas, the climate is dry and continental, with hot summers and cool to cold winters, with occasional snowfall. Outside high-elevation areas, the climate is mostly semi-arid to arid. In lower elevations, summers are hot with blazing sunshine. Winters feature occasional rain or snow from low-pressure systems that cross the area from the Mediterranean Sea. Average monthly precipitation is very low from July to September, rises in autumn and is highest in March or April, followed by swift drying in May and June. Winds can be strong, producing dust storms sometimes, especially toward the end of the summer in September and October. Specific cities that exemplify Central Asian climate patterns include Tashkent and Samarkand, Uzbekistan, Ashgabat, Turkmenistan, and Dushanbe, Tajikistan. The last of these represents one of the wettest climates in Central Asia, with an average annual precipitation of over.
Biogeographically, Central Asia is part of the Palearctic realm. The largest biome in Central Asia is the temperate grasslands, savannas, and shrublands biome. Central Asia also contains the montane grasslands and shrublands, deserts and xeric shrublands and temperate coniferous forests biomes.
Central Asia is considered one of the world's most vulnerable regions to climate change, with temperatures rising faster than the global average. Research suggests that the region's resource-intensive development models and lack of scholarship on social-science adaptation efforts limit the development of evidence-based climate policy.
