There is an Uzbek enclave called Sokh — 325 square kilometers of Uzbek sovereign territory completely surrounded by Kyrgyzstan — that is 99.5% ethnically Tajik. An Uzbek territory, populated by Tajiks, trapped inside Kyrgyzstan. The only way to reach Sokh from mainland Uzbekistan is by air — a tiny propeller plane that flies four times a week from Fergana Airport at 8 AM, with no published schedule and tickets available only at the counter. There is no road access. The borders are mined. The residents of Sokh are Uzbek citizens who speak Tajik, are governed by Uzbekistan, surrounded by Kyrgyzstan, and ethnically connected to Tajikistan. They belong, in the strictest administrative sense, to a country they cannot drive to, speak the language of a country that does not govern them, and are surrounded by a country that periodically seals its border when tensions rise — which they do, because the Fergana Valley has experienced roughly 20 armed conflicts since 1989, and the borders that cause them were drawn by Russian bureaucrats in the 1920s who had, in many cases, never visited the territories they were dividing.
The Fergana Valley is approximately 22,000 square kilometers of fertile lowland — the most densely populated region in Central Asia, home to roughly 14 million people — split between Uzbekistan (which holds the valley floor), Kyrgyzstan (which holds the eastern and southern highlands), and Tajikistan (which holds the western and southwestern margins). Six enclaves — four Uzbek territories inside Kyrgyzstan (Sokh, Shakhimardan, Chon-Gara, Tash-Tepa) and two Tajik territories inside Kyrgyzstan (Vorukh, Kairagach) — dot the valley’s borders like bubbles frozen in ice. Each one is a community physically severed from the country it belongs to, surrounded by a country it does not, and connected to its mainland by roads that cross international borders that did not exist when the enclaves were created. The borders were internal administrative lines within the Soviet Union. When the Soviet Union dissolved in 1991, the lines became international borders overnight — without anyone moving, without any population exchange, without any of the 14 million residents of the valley being consulted. The Ilemi Triangle post documented colonial borders drawn through landscapes the cartographers had never visited. The Fergana Valley is the Central Asian version: Soviet borders drawn through communities the bureaucrats didn’t understand, in a language (Russian) most of the affected populations didn’t speak, using ethnic categories (Uzbek, Kyrgyz, Tajik) that didn’t map cleanly onto communities that had intermarried, traded, and shared irrigation infrastructure for centuries.
How the borders were made
The process that created the Fergana Valley’s borders has a name: razmezhevanie — the Soviet national-territorial delimitation of 1924-1936. Stalin’s nationalities policy required that each ethnic group in Central Asia be assigned its own Soviet republic. The problem was that Central Asian identity in the 1920s was organized around clan, tribe, religious practice, and sedentary-vs-nomadic lifestyle — not around the European-style ethnic-national categories the Soviet system demanded. A farmer in the Fergana Valley might speak Tajik at home, Uzbek in the market, and Russian to officials, belong to a clan that intermarried freely across linguistic groups, and identify himself by his village or tribe rather than by any nationality Moscow would recognize. The Soviet ethnographers who conducted the razmezhevanie were working from incomplete linguistic surveys, contradictory census data, and political imperatives that frequently overrode demographic reality. Uzbek-majority cities were assigned to Tajikistan. Tajik-majority villages were assigned to Uzbekistan. Kyrgyz-majority pastures were divided between all three republics based on considerations that had more to do with economic planning than ethnic logic.
The enclaves were the most extreme artifacts of this process. Sokh was assigned to Uzbekistan in the 1920s, when it was directly connected to the Uzbek SSR. In 1955, Moscow transferred the northern section to Kyrgyzstan, turning Sokh into an island. Nobody in Sokh was consulted. Nobody needed to be — the border was internal to the Soviet Union, and Soviet citizens moved freely across republic lines. The North Sentinel Island post documented a population governed by laws it has never heard of. The residents of Sokh are governed by borders they had no role in creating, which became international frontiers without their consent, in a process conducted in a language many of them did not speak, by a state that no longer exists.
The blood over water
The resource that turns the Fergana Valley’s border absurdities from administrative inconveniences into lethal conflicts is water. The Syr Darya — Central Asia’s second-longest river — flows through the valley, fed by tributaries descending from the mountains of Kyrgyzstan and Tajikistan. Soviet-era irrigation infrastructure distributed the water across all three republics through a unified system that assumed centralized control. After 1991, the water infrastructure was divided among three independent states whose interests diverged immediately: Kyrgyzstan and Tajikistan, the upstream countries, wanted to use the water for hydroelectric power generation (winter electricity). Uzbekistan, the downstream country, wanted the water for cotton irrigation (summer agriculture). The seasonal conflict — upstream wants to release water in winter for power, downstream wants it held until summer for crops — has never been resolved.
The Golovnoi water distribution facility — located at the edge of the Tajik enclave of Vorukh, inside Kyrgyz territory — became the Fergana Valley’s most contested infrastructure. In April 2021, a dispute over surveillance cameras installed by Tajik authorities at the facility escalated from rock-throwing to gunfire. Thirty people were killed. Thousands were displaced. The Battlefields of the Future course covers how modern conflicts increasingly center on critical infrastructure rather than territory in the abstract. The Fergana Valley is the proof case at the smallest scale: two countries went to war over a water pump.
In September 2022, the conflict escalated dramatically. Kyrgyz and Tajik armed forces clashed along the Batken border — tanks, rocket artillery, drone strikes — in fighting that killed at least 100 people and displaced 120,000 Kyrgyz civilians from the Batken region. The 2022 fighting was the most intense interstate military conflict in Central Asia since independence, and it took place between two members of the same Russian-led security organizations — the CSTO and the Shanghai Cooperation Organization — neither of which intervened.
Tajikistan’s Rogun Dam — under construction on the Vakhsh River — is the upstream infrastructure project that could reshape the valley’s water dynamics permanently. When completed, Rogun will be the tallest dam on Earth at 335 meters. Uzbekistan spent a decade opposing it, arguing that the dam would give Tajikistan the ability to restrict downstream water flow at will. The rare earth and conflict minerals literature documents how resource control in contested territories funds conflict. In the Fergana Valley, the resource is water, and the conflict it generates is interstate rather than internal.
The March 2025 breakthrough
In March 2025, Kyrgyzstan, Tajikistan, and Uzbekistan signed a historic trilateral border treaty — the first comprehensive agreement on the Fergana Valley’s borders since independence. The Kyrgyz-Tajik component included land swaps negotiated over four years: the Vorukh enclave was reduced from 19,000 to 14,500 hectares. Kyrgyzstan transferred 1,000 hectares around Vorukh to Tajikistan and received 1,000 hectares of Karagansay in the Chon-Alai district. The Golovnoi water facility was split equally — 1.5 hatches for each country. The village of Dostuk was transferred to Tajikistan in exchange for 91 hectares elsewhere plus resettlement land.
The treaty resolved approximately 95% of the Kyrgyz-Tajik border and a significant portion of the Kyrgyz-Uzbek border. It did not resolve the enclaves — Sokh, Shakhimardan, and Vorukh remain — but it established the framework within which enclave negotiations could proceed. The agreement is the most significant diplomatic achievement in Central Asian interstate relations since the 1990s. Whether it holds depends on whether the water keeps flowing — because every prior agreement in the valley’s history has broken down when drought, dam construction, or upstream unilateral action disrupted the irrigation supply that 14 million people depend on.
The Western Sahara post documented a territory where the referendum that was supposed to resolve the dispute has been prevented for 35 years. The Abkhazia post documented a territory whose relationship with its patron is structurally unresolvable. The Fergana Valley’s March 2025 treaty is the rare Off The Map case study that is moving toward resolution rather than away from it — slowly, partially, with the hardest problems (the enclaves, the Rogun Dam, the ethnic minorities trapped on the wrong side of lines they didn’t draw) still unresolved, but moving.
Why it’s in the course
The Fergana Valley is the Off The Map case study in what happens when internal administrative lines become international borders without anyone asking the population. The Ilemi Triangle is colonial cartographic failure — five lines drawn through a landscape the cartographers hadn’t visited. The Fergana Valley is ideological cartographic failure — borders drawn to implement an ethnic-national theory that didn’t match the population it was applied to, by a state that prioritized administrative tidiness over human geography, and then dissolved, leaving the tidiness as the only surviving artifact of its existence.
Transnistria exists because Russia sustains it. Somaliland exists because its population built it. Azawad exists because a coalition just seized it by force. The Fergana Valley’s enclaves exist because nobody undid what the Soviets did — and for thirty years, the cost of undoing it (land swaps, population resettlement, infrastructure division) exceeded the cost of living with it. Then the fighting started over a water pump, and the cost calculation changed. The March 2025 treaty is the evidence that territorial disputes can be resolved when the alternative becomes lethal. It is also the evidence that resolution takes 34 years, dozens of deaths, 120,000 displaced civilians, and a dam that hasn’t been built yet.
This is the kind of place our Off The Map course was built to map — where an Uzbek enclave populated by Tajiks trapped inside Kyrgyzstan is accessible only by a propeller plane that flies four times a week with no published schedule, two countries fought a war over a water pump at the edge of a 45,000-person enclave, the borders were drawn by Soviet bureaucrats who didn’t speak the local languages, and the treaty that might finally resolve the mess took 34 years, several hundred deaths, and the recognition that the alternative to negotiation was a valley of 14 million people with three armies, six enclaves, one river, and no agreement on who gets the water.
