Home / Mil-Qarabax geography
The South Caucasus is a region where the earth’s bones are not just a foundation for landscapes, but for narratives of identity, conflict, and resilience. At its heart lies the territory known internationally as Nagorno-Karabakh, called Artsakh by its former Armenian inhabitants and an integral part of Azerbaijan following the military campaign of 2023. This is not merely a disputed land; it is a living textbook where geography dictates destiny and geology fuels both economy and strife. To understand the seismic political shifts of today, one must first comprehend the ancient rocks and rugged mountains that shaped them.
Nagorno-Karabakh is defined by its highland core, a rugged block of the Lesser Caucasus mountain range. This is not a gentle landscape. Its average elevation hovers around 1,100 meters, with peaks like Mount Murovdag stretching towards 3,724 meters. This topography is the primary actor in the region’s human drama.
The central plateau is dissected by deep river gorges and dense forests, historically creating natural strongholds. The terrain inherently favors defense, a geographical fact that for decades allowed the de facto Republic of Artsakh to sustain itself against a more powerful adversary. Key passes and valleys, like the Lachin corridor—the former lifeline connecting the enclave to Armenia—were not just roads but geopolitical pressure points. Control of the high ground meant control over movement, communication, and ultimately, survival. The 2023 offensive starkly demonstrated how modern warfare, particularly drone technology, can rewrite these age-old rules of mountainous defense, but the land's imposing nature remains a central factor in any security calculation.
Two major river systems carve through the territory: the Tartar River flowing eastward towards the Mingachevir reservoir in Azerbaijan proper, and the Hakari River in the south. These waterways are crucial for irrigation in the agricultural lowlands of Azerbaijan, making their upstream origins in the Karabakh highlands a matter of vital national interest. Water security here is directly tied to territorial control—who holds the mountains controls the spigot for the plains below. This hydro-politics adds a critical, often underreported, layer to the conflict, where dams and reservoirs become potential strategic assets.
If the mountains form the stage, the subsurface geology writes a compelling and dangerous subplot. The region sits on a complex tectonic suture where the Arabian plate nudges against the Eurasian plate, a process that has not only uplifted the Caucasus but also endowed it with significant mineral wealth.
The Lesser Caucasus belt is rich in polymetallic deposits. Nagorno-Karabakh has known resources of copper, molybdenum, zinc, and most notably, gold. The Zod gold mine, one of the largest in the region, became a symbol of the economic stakes involved. Operated by the de facto authorities prior to 2023, its output was a key revenue stream. For Azerbaijan, regaining sovereignty over these resources is a matter of both economic recovery and asserting full control over its internationally recognized territory. The exploitation of these deposits now presents a challenge: balancing economic development with the environmental and social sensitivities of a post-conflict zone, potentially involving international partners and scrutiny.
While the highlands themselves are not major hydrocarbon zones, the geography of Karabakh is inextricably linked to the energy landscape of the wider South Caucasus. Azerbaijan’s monumental oil and gas exports travel via pipelines that run south of the mountain range, through territory that was, for years, uncomfortably close to the former line of contact. The resolution of the conflict and the subsequent opening of transport links theoretically secures these energy corridors, facilitating Azerbaijan’s vision of being a hub for east-west trade. Furthermore, the geopolitical realignment reduces perceived risks for foreign energy investments in the broader region.
The most volatile and poignant layer on this physical base is the human geography—a pattern brutally remade by war and displacement.
For centuries, the region was a mosaic of Armenian and Azerbaijani communities, with cultural landscapes reflecting both: Armenian stone monasteries perched on remote cliffs, and Azerbaijani villages in the foothills. The First Nagorno-Karabakh War in the 1990s resulted in the displacement of hundreds of thousands of Azerbaijanis from Karabakh and adjacent districts. For three decades, the territory was administered by Armenians, with Azerbaijani settlements left in ruins. The 2020 war and the exodus of virtually the entire ethnic Armenian population in 2023 have triggered another profound demographic shift. Azerbaijan now faces the colossal task of repopulating and rebuilding ghost towns and scarred landscapes, a process it terms the "Great Return."
A central pillar of Azerbaijan’s post-conflict vision is the Zangezur Corridor concept—a transport link through Armenian territory that would connect mainland Azerbaijan to its Nakhchivan exclave and onward to Turkey. While this depends on Armenian agreement, it highlights how the new political geography aims to re-engineer regional connectivity. Within Karabakh, Azerbaijan is rapidly constructing new roads, airports (like the one in Fuzuli), and smart villages. This physical restructuring is an attempt to cement sovereignty not just through military presence, but through the transformative imprint of modern infrastructure, altering the very look and function of the land.
The region’s fragile ecology is both a victim of conflict and a challenge for the future. Unexploded ordnance contaminates forests and pastures. The intense trench warfare of the past three decades has left scars on the landscape. Furthermore, climate change presents a shared threat: changing precipitation patterns could stress water resources, and increased temperatures could exacerbate drought. Sustainable management of the region’s forests, which are vital for biodiversity and soil stability, and its water resources will require unprecedented cooperation or risk becoming a new source of tension. The environmental recovery of Nagorno-Karabakh is a silent but critical front in its long-term stability.
The story of Nagorno-Karabakh is written in limestone and shale, in river flow and mountain passes, in gold veins and oil routes. Its geography made it a fortress, its geology made it a prize, and their interplay made it a battleground. As the world’s attention shifts to other crises, the ancient rocks of the Lesser Caucasus continue to bear witness to a new chapter—one of uncertain peace, monumental reconstruction, and a landscape whose physical form is once again being actively shaped by the relentless will of those who claim it. The terrain no longer echoes with artillery, but the deeper tremors of transformation are still being felt, proving that in this corner of the world, the ground itself is history.
