10.1 North and Central Eurasia: A Continent Masquerading as a Region

 Learning Objectives

By the end of this chapter, students should be able to:

Explain how continentality, latitude, permafrost, mountains, rivers, and water scarcity shape settlement and transportation across North and Central Eurasia.

Compare Russia's demographic contraction with the younger and faster-growing populations of Central Asia.

Describe the region's cultural and religious diversity without treating Russian or Soviet identity as a complete description of its peoples.

Trace how the Russian Empire and Soviet Union reorganized territory, population, language, agriculture, and industry.

Explain why the collapse of the Soviet Union in 1991 did not erase the spatial systems created under Soviet rule.

Analyze the war in Ukraine as a struggle over territory, sovereignty, infrastructure, identity, and the meaning of empire.

Evaluate how oil, natural gas, minerals, pipelines, rail corridors, sanctions, and China's growing influence are changing regional power.

Identify the geographic choices facing the region as climate change alters the Arctic, the Caspian basin, glaciers, and Central Asian water supplies.

Entering the Region

Board the Trans-Siberian Railway in Moscow and the first lesson is not scenery. It is duration.

The train moves east through cities, birch forests, industrial towns, rivers, farms, and long intervals where the horizon seems to have misplaced the next settlement. Time zones accumulate. Europe recedes, although no coastline announces that Asia has begun. After days rather than hours, the train reaches Lake Baikal, then continues toward the Russian Far East. A map can compress this journey into a line. The body cannot.

North and Central Eurasia is a region in which distance has repeatedly become a political problem. Armies had to cross it. Grain had to move across it. Nomadic communities learned to use movement rather than resist it. Imperial governments built forts, railroads, canals, pipelines, collective farms, mining settlements, and entire industrial cities to make distant territory governable. Soviet planners sometimes moved factories thousands of kilometers and populations against their will. After 1991, new international borders cut through transportation grids and economic relationships that had been designed for one state.

The region in this chapter includes Russia, Ukraine, Belarus, Moldova, Georgia, Armenia, Azerbaijan, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. These countries do not form a single cultural civilization, political alliance, or environmental zone. Ukraine is a large European state fighting to defend itself from Russian invasion. Georgia, Armenia, and Azerbaijan occupy the Caucasus, where mountains, empires, religions, and trade routes meet. Kazakhstan stretches from the Caspian Sea toward China. Kyrgyzstan and Tajikistan are mountainous. Uzbekistan contains the region's largest Central Asian population. Turkmenistan combines desert geography, natural gas, and one of the world's most closed political systems. Moldova sits between Romania and Ukraine, with a contested political geography of its own.

Even the phrase North and Central Eurasia requires care. It is useful because the region contains shared imperial histories, Soviet legacies, transportation systems, migration routes, and environmental problems. It becomes misleading when it turns Russia into the center and everyone else into a peripheral "former Soviet republic." A country is not a former anything to the people trying to build its present.

This chapter moves through four connected questions:

Physical and environmental geography: How do cold, distance, water, mountains, and continental scale shape the region?

Population, culture, and everyday life: Who lives here, and how do language, religion, food, migration, and cities reveal many overlapping Eurasias?

Historical and political geography: How did empires organize space, and why do their borders and institutions remain politically alive?

Economy, geopolitics, and the future: How are pipelines, war, sanctions, China, climate change, and new trade corridors changing the balance of power?

The argument running through all four is simple: North and Central Eurasia has repeatedly been organized by states attempting to overcome distance. Its modern geography is the record of what those states built, moved, suppressed, connected, and never entirely controlled.

Part I. A Continent Masquerading as a Region

The Tyranny and Possibility of Distance

Russia is the world's largest country by area. That fact is familiar enough to become almost meaningless. Students see a vast shape stretched across the top of a map and assume that size itself is power. It can be. Size can provide minerals, forests, farmland, energy resources, strategic depth, and access to several seas. It can also demand roads, railways, communications, heating systems, military logistics, and public services across immense distances. Territory is an asset that sends maintenance bills.

The region extends from the Baltic and Black seas to the Pacific, and from the Arctic Ocean south toward Afghanistan, Iran, and China. No single environmental description can contain it. Arctic tundra gives way to taiga, the broad belt of boreal forest that crosses northern Eurasia. Farther south are mixed forests, forest-steppe, grasslands, agricultural zones, dry basins, and deserts. The Caucasus and the mountains of Central Asia interrupt these broad latitudinal bands. Elevation can create alpine conditions far south of the Arctic.

The scale is easiest to understand through movement. Moscow and Vladivostok are separated by roughly the distance between Minnesota and the far side of the Atlantic, and the Trans-Siberian route between them crosses eight time zones. The Soviet Union built transportation as a political instrument, but rail and road density remained much greater in the west. Even today, Russia's population, institutions, and transportation networks are concentrated heavily in the European portion of the country. Siberia is not empty, but it is expensive to connect.

Central Asia presents a different geometry. All five Central Asian states are landlocked, and Uzbekistan is one of only two doubly landlocked countries in the world. To reach an ocean from Uzbekistan, freight must cross at least two national borders. This is not merely an inconvenience. Every border adds paperwork, inspection, fees, political risk, and the possibility that a neighboring state may close a route. Geography does not prevent trade, but it raises the price of friction.

Continentality: When the Ocean Is Far Away

Much of North and Central Eurasia has a strongly continental climate. Oceans moderate temperature because water warms and cools more slowly than land. Far from the ocean, seasonal temperature ranges often become larger. Summers can be surprisingly hot. Winters can become severe.

Siberia supplies some of the most dramatic examples. In parts of the interior, average January temperatures fall below -40 degrees Celsius. The cold is not simply a number on a weather map. Metal becomes brittle. Batteries lose power. Engines require special care. Buildings, pipelines, roads, and rail beds must be designed for freezing, thawing, and frost movement. A winter road across frozen ground may provide access for several months and then vanish into mud or water.

Central Asia is also continental, but latitude and elevation create different combinations. Kazakhstan has cold winters and hot summers across much of its steppe. Uzbekistan and Turkmenistan contain extensive deserts, with intense summer heat and limited precipitation. Kyrgyzstan and Tajikistan rise into the Tian Shan and Pamir mountains, where high elevation produces cold conditions, glaciers, and sharply different climates over short distances.

The term continentality helps explain these patterns, but it does not replace local geography. The Caspian Sea influences nearby climates. Mountain ranges redirect winds and precipitation. Irrigation changes local humidity and vegetation. Cities create heat islands. Climate categories are useful only if we remember that nobody actually lives inside a category.

Tundra, Taiga, Steppe, and Desert

The tundra lies across the far north, where low temperatures, short growing seasons, and permafrost limit tree growth. Vegetation includes mosses, lichens, grasses, sedges, and low shrubs. This landscape may look sparse to an outsider, but it supports migratory birds, reindeer, fish, insects, predators, and human communities with highly specialized knowledge.

South of the tundra lies the taiga, the largest forest belt on Earth. Conifers dominate much of it, though species and conditions vary across thousands of kilometers. The forest stores carbon, supports timber industries, and provides habitat for bears, wolves, lynx, sable, and many other species. Fire is a natural part of boreal ecology, yet hotter and drier conditions can lengthen fire seasons and increase the severity of some fires. Smoke does not respect the boundary of the forest that produced it.

The steppe stretches across southern Russia, Ukraine, and Kazakhstan. Its grasslands have supported pastoral mobility, grain farming, military movement, and imperial expansion. The same broad openness that nourished herds and crops also created corridors along which peoples, technologies, religions, and armies moved between East Asia, the Middle East, and Europe. The steppe was never an empty interval between civilizations. It was one of the systems connecting them.

Farther south and east, aridity becomes more prominent. The Karakum Desert covers much of Turkmenistan, while the Kyzylkum extends across Uzbekistan and Kazakhstan. Deserts contain settlements, infrastructure, grazing lands, irrigated oases, mines, gas fields, and long histories of trade. Calling them "empty" usually means that the observer has not learned what to look for.

Permafrost: Ground That Keeps a Memory of Cold

Permafrost is ground that remains at or below freezing for at least two consecutive years. It may contain soil, rock, sand, organic material, and large amounts of ice. The upper active layer freezes and thaws seasonally. Across northern Russia, communities and engineers have built on the expectation that deeper ground would remain frozen.

Climate change is altering that expectation. When ice-rich permafrost thaws, the ground can settle unevenly. Roads buckle, building foundations shift, pipelines bend, and lake and river systems change. Thaw can also expose older organic material to decomposition, releasing carbon dioxide and methane. The result is a feedback: warming thaws frozen ground, and thaw can add greenhouse gases that contribute to further warming (National Snow and Ice Data Center, n.d.).

Norilsk provides a harsh illustration. The city was built as a center of nickel and other metal production in the Russian Arctic. Its industrial landscape rests partly on permafrost and carries a long legacy of pollution and coerced labor. In 2020, a fuel storage tank near the city failed, releasing diesel into rivers and soils. Investigations debated the precise mixture of maintenance failure, design, and thawing ground. The geographic lesson is that climate change rarely acts alone. It enters systems already shaped by aging infrastructure, corporate decisions, weak oversight, and earlier environmental damage.

Permafrost should therefore not be treated as scenery melting in the distance. It is foundation, archive, habitat, infrastructure, and carbon store. Frozen ground is part of the region's built environment even where no engineer created it.

Rivers That Flow the "Wrong" Way

Several of Russia's great rivers flow north into the Arctic Ocean, including the Ob, Yenisei, and Lena. On a physical map, this seems ordinary. In spring, however, southern portions of a river may thaw before northern portions. Water moving north can encounter ice, producing jams and floods. The rivers also run away from many of the country's densest population centers and traditional trade partners.

The Volga follows a different path. It drains south into the Caspian Sea and has long served as a central artery of European Russia. Canals connect it to other river systems and seas, turning it into part of a wider transportation network. Cities, factories, reservoirs, farms, and cultural histories line its course. The Volga is a river, but it is also an engineered corridor and a national symbol.

The Dnieper flows through Russia, Belarus, and Ukraine before reaching the Black Sea. Dams and reservoirs made it central to Soviet electricity, industry, irrigation, and navigation. War transformed that infrastructure into a target and a weapon. The destruction of the Kakhovka Dam in June 2023 flooded downstream settlements, drained the reservoir, damaged ecosystems and agriculture, and altered water access. A river system built to bind a territory together became part of the geography of invasion.

Central Asia's major rivers begin largely in mountain regions. The Amu Darya and Syr Darya flow toward the Aral basin. Water stored as snow and glacier ice in Kyrgyzstan and Tajikistan supports irrigation and cities downstream in Kazakhstan, Turkmenistan, and Uzbekistan. This produces a classic geographic tension. Upstream states often value winter hydropower generation. Downstream states need summer water for crops. A dam schedule is therefore also a diplomatic schedule.

Lake Baikal, the Caspian Sea, and the Aral Sea

Lake Baikal is the world's deepest and oldest lake. It contains nearly one-fifth of the world's unfrozen surface freshwater and supports an extraordinary number of endemic species, including the Baikal seal (UNESCO World Heritage Centre, n.d.). It is tempting to describe the lake only with superlatives. The more revealing geography lies in the conflict between global ecological value and local economic use. Tourism, shoreline development, pollution, fires, logging pressures, and industrial legacies all affect the lake and its watershed. UNESCO has continued to express concern about water quality, development, and management (UNESCO World Heritage Centre, 2025).

The Caspian Sea is the world's largest enclosed inland body of water. Russia, Kazakhstan, Turkmenistan, Iran, and Azerbaijan share its shores. It supports fisheries, ports, energy production, and distinctive ecosystems. Because it has no outlet to the ocean, its level depends heavily on river inflow, evaporation, and climate. The Caspian has been shrinking, and recent modeling suggests substantial further decline by the 2050s. A falling water level can strand ports, disrupt habitats, change coastlines, and complicate oil and gas infrastructure (World Bank, 2026a). A coastline on an atlas may look permanent. Around an enclosed sea, it is a moving negotiation between water balance and human investment.

The Aral Sea is the region's most famous environmental catastrophe. Soviet planners expanded cotton and other irrigated agriculture by diverting water from the Amu Darya and Syr Darya. Beginning in the 1960s, the sea shrank dramatically. Fishing towns found themselves far from the water. Exposed lakebed sediments carried salts and pollutants in dust storms. Fisheries collapsed, local climates shifted, and human health suffered.

The phrase "the Aral Sea disappeared" is too simple. The water body fragmented. The North Aral Sea in Kazakhstan partially recovered after the Kok-Aral Dam improved retention of Syr Darya water. Water levels rose, salinity declined, and some fisheries returned. Farther south, much of the former seabed remains exposed. The Aral story is therefore both warning and correction. Environmental destruction can be immense, but geography does not always move in only one direction.

Climate Change Does Not Arrive Alone

The Arctic is warming much faster than the planetary average. Sea ice has declined, glaciers have lost mass, tundra vegetation has changed, and permafrost is warming. In 2025, satellite observations recorded one of the greenest tundra seasons in the modern record, continuing a long-term "greening" pattern that varies by place and does not mean the Arctic has become healthy or stable (National Oceanic and Atmospheric Administration, 2025).

Central Asia faces a different combination of rising heat, glacier loss, drought, flood risk, and water stress. Uzbekistan's average annual temperature has already risen substantially, with especially large increases around the Aral region. UNEP reported six dry years between 2019 and 2024 (United Nations Environment Programme, 2025). Mountain glaciers may initially add meltwater, then provide less as ice volume declines. Agricultural demand may rise during hotter summers just as water becomes less predictable.

Climate change is often described as a new force pressing upon an old map. In this region, it more often enters inherited systems: Soviet irrigation canals, aging apartment blocks, permafrost foundations, hydropower networks, polluted industrial sites, disputed borders, and economies dependent on fossil fuels. The hazard may be physical. The disaster is assembled socially.

The next part descends from continental scale to human scale. A region that looks thinly populated from orbit contains crowded trains, apartment courtyards, bazaars, pilgrimage routes, village weddings, industrial dormitories, refugee households, and languages that have survived more than one attempt to make the map speak with a single voice.
