Kazakhstan is located inCentral Asia, witha small portion inEastern Europe.[1] With an area of about 2,724,900 square kilometers (1,052,100 sq mi)Kazakhstan is the ninth largest country in the world, more than twice the combined size of the other four Central Asian states and 60% larger thanAlaska. The country bordersTurkmenistan,Uzbekistan, andKyrgyzstan to the south;Russia to the north; Russia and theCaspian Sea to the west; and China'sXinjiang Uygur Autonomous Region to the east.
According toCIA World Factbook estimates:[2][3]
More than three-quarters (75%) of the country, including the entire west and most of the south, is either semidesert (33.2 percent) or desert (44 percent).
According toCIA World Factbook estimates:[2]
There is considerable topographical variation within Kazakhstan. The highest point is the top of the mountainKhan Tengri, on the Kyrgyz and Chinese border in theTian Shan range, with an elevation of 6,995 m (22,949 ft) (7,010 m (23,000 ft) with ice cap) above sea level; the lowest point is the bottom of theKaragiye depression at 132 m (433 ft) below sea level, in theMangystau province east of theCaspian Sea. Most of the country lies at between 200–300 m (660–980 ft) above sea level, but Kazakhstan's Caspian shore includes some of the lowest elevations on Earth.
Many of the peaks of theAltay and Tien Shan ranges are covered with snow, year-round, and their runoff is the source for most of Kazakhstan's freshwater rivers, streams, and lakes. Kazakhstan'sAlmaty region is also home to theMynzhylky mountain plateau.
Except for theTobol,Ishim, andIrtysh rivers (the Kazakh names for which are, respectively, Tobyl, Esil, and Ertis), portions of which flow through Kazakhstan, all of Kazakhstan's rivers and streams are part of landlocked systems. They either flow into isolated bodies of water such as the Caspian Sea or simply disappear into the steppes and deserts of central and southern Kazakhstan. Many rivers, streams, and lakes are seasonal, evaporating in summer. The three largest bodies of water areLake Balkhash, a partially fresh, partially saline lake in the east, nearAlmaty, the Caspian Sea, and theAral Sea, all of which lie partially within Kazakhstan.
Some 9.4 percent of Kazakhstan's land is mixedprairie andforest or treeless prairie, primarily in the north or in the basin of theUral River in the west. More than three-quarters of the country, including the entire west and most of the south, is either semidesert (33.2 percent) or desert (44 percent). The terrain in these regions is bare, eroded, brokenuplands (Upland and lowland), with sand dunes in theQizilqum ("The Red Sands"; in the Russian form,Kyzylkum),Moyunqum (in the Russian form, Muyunkum) andBarsuki deserts, which occupy south-central Kazakhstan.

The climate of Kazakhstan consists of mostly continental, semi-arid, and cold desert climates. In summer the temperatures average more than 30 °C (86 °F) and in winter average −9 °C (15.8 °F).[4] Kazakhstan is very vulnerable to climate change.[5]
The climatic charts seen below are some noteworthy examples of the country's differing climates, taken from two contrasting cities (with their respective tables) representing two different parts of the country; Aktau and the Caspian Sea shore on the country's west having a distinctcold desert climate andcold semi-arid climate, while Petropavl features a climate typical to the rest of the country; an extreme variation of thehumid continental climate known for its uneven rainfall distribution and drastic temperature ranges between seasons.
Despite the nation's relatively low precipitation rates and mostly arid geography, spring floods brought on by occasional heavy rainfall and snowmelt are not unusual in the northern and central regions of the country. In April 2017, following a winter with snow volumes 60 percent above average, heavy rains resulted in widespread damage and temporarily displaced thousands of people.[6]

The environment ofKazakhstan has been badly damaged by human activity. Most of the water in Kazakhstan is polluted by industrial effluents, pesticide and fertilizer residue, and, in some places, radioactive elements. The most visible damage has been to theAral Sea, which as recently as the 1970s was larger than any of theGreat Lakes ofNorth America saveLake Superior. The sea began to shrink rapidly when sharply increased irrigation and other demands on the only significant tributaries, theSyr Darya and theAmu Darya (the latter reaching the Aral from neighboring Uzbekistan), all but eliminated inflow. During the Soviet Era, Kazakhstan received water fromTajikistan andKyrgyzstan, andUzbekistan,Turkmenistan, and Kazakhstan provided oil and gas for these two nations in return. However, after thecollapse of the USSR this system had collapsed and no plan to replace this system has been put in place. According to research conducted by theInternational Crisis Group, there is little political will to solve this problem despite Central Asia's need for mutual resource-sharing.[10] By 1993 the Aral Sea had lost an estimated 60 percent of its volume, in the process breaking into three unconnected segments. Increasing salinity and reduced habitat have killed the Aral Sea's fish, hence destroying its once-active fishing industry, and the receding shoreline has left the former port of Aral'sk more than seventy kilometers from the water's edge. The depletion of this large body of water has increased temperature variations in the region, which in turn have affected agriculture. A much greater agricultural impact, however, has come from the salt- and pesticide-laden soil that the wind is known to carry as far away as theHimalaya Mountains and thePacific Ocean. Deposition of this heavily saline soil on nearby fields effectively sterilizes them. Evidence suggests that salts, pesticides, and residues of chemical fertilizers are also adversely affecting human life around the former Aral Sea; infant mortality in the region approaches 10 percent compared with the national rate of 2.7 percent in 1991.
By contrast, the water level of the Caspian Sea has been rising steadily since 1978 for reasons that scientists have not been able to explain fully. At the northern end of the sea, more than 10,000 square kilometres of land inAtyrau Province have been flooded. Experts estimate that if current rates of increase persist, the coastal city of Atyrau, eighty-eight other population centers, and many of Kazakhstan's Caspian oil fields could be submerged soon.
Wind erosion has also affected the northern and central parts of the republic because of the introduction of wide-scale dryland wheat farming. During the 1950s and 1960s, much soil was lost when vast tracts of Kazakhstan's prairies were plowed under as part of Khrushchev's Virgin Lands agricultural project. By the mid-1990s, an estimated 60 percent of the republic's pastureland was in various stages ofdesertification.
Industrial pollution is a bigger concern in Kazakhstan's manufacturing cities, where aging factories pump huge quantities of unfiltered pollutants into the air and groundwater. The former capital, Almaty, is particularly threatened, in part because of the postindependence boom in private automobile ownership.
The gravest environmental threat to Kazakhstan comes from radiation, especially in theSemey (Semipalatinsk) region of the northeast, where theSoviet Union tested almost 500 nuclear weapons, 116 of them above ground. Often, such tests were conducted without evacuating or even alerting the local population. Although nuclear testing was halted in 1990, radiation poisoning, birth defects, severe anemia, andleukemia are thought to be very common in the area.[11]
With some conspicuous exceptions, lip service has been the primary official response to Kazakhstan's ecological problems. In February 1989, opposition to Soviet nuclear testing and its ill effects in Kazakhstan led to the creation of one of the republic's largest and most influential grass-roots movements, Nevada-Semipalatinsk, which was founded by Kazak poet and public figureOlzhas Suleymenov. In the first week of the movement's existence, Nevada-Semipalatinsk gathered more than two million signatures from Kazakhstanis of all ethnic groups on a petition toMikhail Gorbachev demanding the end of nuclear testing in Kazakhstan. After a year of demonstrations and protests, the test ban took effect in 1990. It remained in force in 1996, although in 1995 at least one unexploded device reportedly was still in position near Semey.
Once its major ecological objective was achieved, Nevada-Semipalatinsk made various attempts to broaden into a more general political movement; it has not pursued a broad ecological or "green" agenda. A very small green party, Tabigat, made common cause with the political opposition in the parliament of 1994.
The government has established a Ministry of Ecology and Bioresources, with a separate administration forradioecology, but the ministry's programs are underfunded and given low priority. In 1994 only 23 percent of budgeted funds were actually allotted to environmental programs. Many official meetings and conferences are held (more than 300 have been devoted to the problem of the Aral Sea alone), but few practical programs have gone into operation. In 1994 theWorld Bank, theInternational Monetary Fund (IMF), and theUnited States Environmental Protection Agency agreed to give Kazakhstan $62 million to help the country overcome ecological problems.
