Geography of the Soviet Union

right|thumb|500px|Physical map of the Soviet Union

The Soviet Union incorporated an area of over , covering approximately one-sixth of Earth's land surface. It spanned most of Eurasia. Its largest and most populous republic was the Russian SFSR which covered roughly three-quarters of the surface area of the union, including the complete territory of contemporary Russia.

The Soviet Union was the world's largest country throughout its entire existence (1922–1991). It had a geographic center further north than all independent countries other than Canada, Iceland, Finland, and the countries of Scandinavia. About three-quarters of the country was above the 50th parallel north.

Geographical particulars

Area

The country's 22,402,200 square kilometers (8,649,537.8 sq mi) included one-sixth of the Earth's land surface. Its western portion covered more than half of the land area of Europe but only a quarter of the total land area of the Soviet Union. This area was where the majority (about 72 percent) of the people lived and where most industrial and agricultural activities were concentrated. It was here, roughly between the Dnieper River and the Ural Mountains, that its predecessor, the Russian Empire, took shape and gradually over centuries expanded to the Pacific Ocean and into Central Asia. After the Russian Civil War, the newly formed Soviet Union took control over most of the empire's former territories.

Borders and neighbors

The Soviet Union had the longest borders of any contemporary country, extending approx. .

Topography and drainage

Most geographers divide the vast Soviet territory into five natural zones that generally extend from west to east: the tundra zone; the taiga or forest zone; the steppe or plains zone; the arid zone; and the mountain zone. Most of the Soviet Union consisted of three plains (East European Plain, West Siberian Plain, and Turan Lowland), two plateaus (Central Siberian Plateau and Kazakh Upland), and a series of mountainous areas, concentrated for the most part in the extreme northeast or extending intermittently along the southern border. The West Siberian Plain, the world's largest, extended east from the Urals to the Yenisey River. Because the terrain and vegetation were uniforms in each of the natural zones, the Soviet Union, as a whole, presented an illusion of uniformity.

Tundra

Nevertheless, the Soviet territory contained all the major vegetation zones with the exception of tropical rain forest. Ten percent of Soviet territory is tundra, that is, a treeless marshy plain. The tundra was the Soviet Union's northernmost zone of snow and ice, stretching from the Finnish border in the west to the Bering Strait in the east and then running south along the Pacific coast to the earthquake and volcanic region of northern Kamchatka Peninsula. It was the land made famous by herds of wild reindeer, by white nights (dusk at midnight, dawn shortly thereafter) in summer, and by days of total darkness in winter. The long harsh winters and lack of sunshine allowed only mosses, lichens, and dwarf willows and shrubs to sprout low above the barren permafrost. Although the great Siberian rivers slowly traversed this zone in reaching the Arctic Ocean, drainage of the numerous lakes, ponds, and swamps was hampered by partial and intermittent thawing. Frost weathering is the most important physical process here, shaping a landscape modified by extensive glaciation in the last ice age.

Forests

The northern forests of spruce, fir, pine, and larch, collectively known as the taiga, made up the largest natural zone of the Soviet Union, an area about the size of the United States. Here too the winter is long and severe, as witnessed by the routine registering of the world's coldest temperatures for inhabited areas in the northeastern portion of this belt. The taiga zone extended in a broad band across the middle latitudes, stretching from the Finnish border in the west to the Verkhoyansk Range in northeastern Siberia and as far south as the southern shores of Lake Baykal. Isolated sections of taiga are found along mountain ranges, as in the southern part of the Urals, and in the Amur River Valley in the Far East. About 33 percent of the population lives in this zone, which, with the mixed forest zone, included most of the European part of the Soviet Union and the ancestral lands of the earliest Slavic settlers.

Steppes

Long associated with traditional images of Russian landscape and cossacks on horseback are the steppes, which are treeless, grassy plains. Although they covered only 15 percent of Soviet territory, the steppes were home to roughly 44 percent of the population. They extend for 4,000 kilometers from the Carpathian Mountains in the western Ukrainian Republic across most of the northern portion of the Kazakh Republic in Soviet Central Asia, between the taiga and arid zones, occupying a relatively narrow band of plains whose chernozem soils are some of the most fertile on earth. In a country of extremes, the steppe zone, with its moderate temperatures and normally adequate levels of sunshine and moisture, provides the most favorable conditions for human settlement and agriculture. Even here, however, agricultural yields were sometimes adversely affected by unpredictable levels of precipitation and occasional catastrophic droughts.

Arid zone

Below the steppes, and merging at times with them, was the arid zone: the semideserts and deserts of Soviet Central Asia and, particularly, of the Kazakh Republic. Portions of this zone became cotton- and rice-producing regions through intensive irrigation. For various reasons, including sparse settlement and a comparatively mild climate, the arid zone became the most prominent center for Soviet space exploration.

One-quarter of the Soviet Union consisted of mountains or mountainous terrain. With the significant exceptions of the Ural Mountains and the mountains of eastern Siberia, the mountains occupy the southern periphery of the Soviet Union. The Urals, because they have traditionally been considered the natural boundary between Europe and Asia and because they are valuable sources of minerals, were the most famous of the country's nine major ranges. In terms of elevation (comparable to the Appalachians) they do not serve as a formidable natural barrier.

Alpine terrain

Truly alpine terrain was found in the southern mountain ranges. Between the Black and Caspian seas, for example, the Caucasus Mountains rose to impressive heights, marking a continuation of the boundary separating Europe from Asia. One of the peaks, Mount Elbrus, is the highest point in Europe at 5,642 meters. This range, extending to the northwest as the Crimean and Carpathian mountains and to the southeast as the Tien Shan and Pamirs, formed an imposing natural barrier between the Soviet Union and its neighbors to the south. The highest point in the Soviet Union, at 7,495 meters, was Mount Communism (Pik Kommunizma) in the Pamirs near the border with Afghanistan, Pakistan, and China. The Pamirs and the Tien Shan were offshoots of the tallest mountain chain in the world, the Himalayas. Eastern Siberia and the Soviet Far East are also mountainous regions, especially the volcanic peaks of the long Kamchatka Peninsula, which jutted down into the Sea of Okhotsk. The Soviet Far East, the southern portion of Soviet Central Asia, and the Caucasus were the Soviet Union's centers of seismic activity. In 1887, for example, a severe earthquake destroyed the city of Verny (present-day Almaty), and in December 1988 a massive quake demolished the Armenian city of Spitak and large sections of Kirovakan and Leninakan. The 1988 quake, one of the worst in Soviet history, claimed more than 25,000 lives.

Hydrosystems

The Soviet Union possessed both scarce and abundant water resources. With about 3 million rivers and approximately 4 million inland bodies of water, the Soviet Union held the largest fresh, surface-water resources of any country. But most of these resources (84 percent), as with so much of the Soviet resource-base, lay at a great distance from the majority of potential users; they flowed through sparsely populated territory and into the Arctic and Pacific oceans. In contrast, areas with the highest concentrations of the population (and therefore the highest demand for water supplies) tended to have the warmest climates and highest rates of evaporation. This resulted in barely adequate (or in some cases inadequate) water-resources in the areas of most need.

Nonetheless, as in many other countries, the earliest settlements sprang up on the rivers, where the majority of the urban population preferred to live. The Volga, Europe's longest river, became by far the Soviet Union's most important commercial waterway. Three of the country's twenty-three cities with more than one million inhabitants stood on its banks: Gorky, Kazan, and Kuybyshev.

The European part of the Soviet Union had extensive, highly developed, and heavily used water-resources, among them the key hydrosystems of the Volga, Kama, Dnepr, Dnestr, and Don rivers. As with fuels, however, the greatest water resources lay east of the Urals, deep in Siberia. Of the sixty-three rivers in the Soviet Union longer than 1,000 kilometers, forty were east of the Urals, including the four mighty rivers that drain Siberia as they flow northward to the Arctic Ocean: the Irtysh, Ob', Yenisey, and Lena rivers. The Amur River formed part of the winding and even at times there are tense boundaries between the Soviet Union and People's Republic of China. Taming and exploiting the hydroelectric potential of these systems became a monumental and highly publicized Soviet project. Some of the world's largest hydroelectric stations operated on these rivers. Hundreds of smaller hydroelectric power-plants and associated reservoirs were also constructed on the rivers. Thousands of kilometers of canals linked river- and lake-systems and provided essential sources of irrigation for farmland.

The Soviet Union's four million inland bodies of water chiefly resulted from extensive glaciation. Most prominently they included the Caspian Sea, the world's largest inland sea, and Lake Baikal, the world's deepest and most capacious freshwater lake. Lake Baikal alone held 85 percent of the freshwater resources of the lakes in the Soviet Union and 20 percent of the world's total. Other water resources included swampland - a sizable portion of territory (10 percent) - and glaciers in the northern areas.

Climate

Winter's impact

Notorious cold and long winters have been the focus of discussions on the Soviet Union's weather and climate. From the frozen depths of Siberia came baby mammoths perfectly preserved, locked in ice for several thousand years. Millions of square kilometers experience half a year of subfreezing temperatures and snow covered over subsoil that was permanently frozen in places to depths of several hundred meters. In northeastern Siberia, not far from Yakutsk, hardy settlers coped with January temperatures that consistently average . Transportation routes, including entire railroad lines, had been redirected in winter to traverse rock-solid waterways and lakes.

Howling Arctic winds that produced coastal wind chills as low as and the burany, or blinding snowstorms of the steppe, were climatic manifestations of the USSR's close proximity to the North Pole and remoteness from oceans that tended to moderate the climate. A combination of the "Siberian high": cold, high-pressure systems in the east, together with wet, cold cyclonic systems in the west largely determined the overall weather patterns.

The long, cold winter had a profound impact on almost every aspect of life in the Soviet Union. It affected where and how long people live and work and what kinds of crops are grown and where they are grown (no part of the country has a year-round growing season). The length and severity of the winter, along with the sharp fluctuations in the mean summer and winter temperatures, imposed special requirements on many branches of the economy: in regions of permafrost, buildings must be constructed on pilings, and machinery must be made of specially tempered steel; transportation systems must be engineered to perform reliably in extremely low and high temperatures; the health care field and the textile industry are greatly affected by the ramifications of six to eight months of winter; and energy demands are multiplied by extended periods of darkness and cold.

Other climatic zones

Despite its well-deserved reputation as a generally snowy, icy northern country, the Soviet Union included other major climatic zones as well. According to Soviet geographers, most of their country is located in the temperate zone, which for them included all of the European portions except the southern part of Crimea and the Caucasus, all of Siberia, the Soviet Far East, and the plains of Soviet Central Asia and the southern Kazakh Republic.

Two areas outside the temperate zone demonstrated the climatic diversity of the Soviet Union: the Soviet Far East, under the influence of the Pacific Ocean, with a monsoonal climate; and the subtropical band of territory extending along the southern coast of the Soviet Union's most popular resort area, Crimea, through the Caucasus and into Soviet Central Asia, where there were deserts and oases.

With most of the land so far removed from the oceans and the moisture they provide, levels of precipitation in the Soviet Union was low to moderate. More than half the country received fewer than forty centimeters of rainfall each year, and most of Soviet Central Asia and northeastern Siberia could count on barely one-half that amount. The wettest parts were found in the small, lush subtropical region of the Caucasus and in the Soviet Far East along the Pacific coast.

Land and natural resources

The Soviet resource base was by far the world's most extensive, ensuring self-sufficiency for its people in most resources for many years. The Soviet Union was usually first or second in the annual production of most of the world's strategic raw materials. However, most of the topography and climate resembles that of the northernmost portion of the North American continent. The northern forests and the plains to the south find their closest counterparts in the Yukon Territory and in the wide swath of land extending across most of Canada. Similarities in terrain, climate, and settlement patterns between Siberia and Alaska and Canada are unmistakable.

Land status

Only 11 percent of the USSR's land was arable. 16 percent was meadows and pasture. 41 percent was forest and woodland. Of the remaining, much is permafrost or tundra.

Despite these measures, decades of environmental degradation caused by severe air and water pollution and land abuse are unlikely to be remedied soon or easily. Solving these critical problems will require not only a major redirection of capital and labor but also a fundamental change in the entire Soviet approach to industrial and agricultural production and resource exploitation and consumption.
