Nature de ce terrain
A long, high, mostly undelimited boundary running through terrain where villages, pastures and water sources sit across a line nobody drew precisely. The delimitation problem is a terrain problem before it is a diplomatic one.

Où les mouvements se concentrent
La province méridionale où convergent la frontière arménienne, la frontière iranienne et l’exclave du Nakhchivan. Chaque proposition de corridor et chaque objection iranienne concerne ce terrain.
L’exclave azerbaïdjanaise séparée du reste du pays par le territoire arménien — le fait géographique qui sous-tend toute la question des transports.
Deuxième ville d’Arménie, au nord, face à la frontière turque fermée, et le point où les deux frontières fermées de la région sont le plus proches l’une de l’autre.
Fermée depuis 1993, et la raison pour laquelle les approches nord de la bande n’ont aucun trafic de transit.
Caractère physique
- Terrain dominant
- Montagnes et hautes terres sur toute la longueur, la frontière suivant les lignes de crête, traversant des vallées et passant par endroits directement entre des villages. Le peuplement se situe dans les vallées des deux côtés, souvent en vue de la ligne. Au sud, la bande se resserre autour du Syunik, où la frontière, la frontière iranienne et l’exclave du Nakhchivan convergent sur une courte distance — la raison géographique pour laquelle la question du corridor est aussi sensible.
- Implications pour la mobilité
- Cross-border movement is confined to a small number of valley routes and has been closed since the 1990s. Along the line itself, terrain determines everything: the positions each side holds follow ridgelines and dominating ground, and the practical consequence is that villages, roads, pastures and water sources frequently sit below ground held by the other party. That is the physical basis of the recurring incidents — proximity rather than intent, in a place where the line's exact position has never been agreed.
- Contraintes saisonnières
- Winter closes higher sections and reduces activity along much of the belt; summer brings livestock to upland pastures that in several places straddle the disputed line, which is a recurring source of friction with no political content at all. Agricultural cycles rather than military ones drive much of the movement that produces incidents.
- Eau et obstacles naturels
- Water is the underappreciated element. Several reservoirs, irrigation systems and springs sit on or near the undelimited line, and the 2024 Tavush delimitation involved practical questions about road access and water supply alongside the political ones. In this terrain, delimitation is not an abstract cartographic exercise: moving a line moves who can reach a spring.
- Urbanisation et peuplement
- Des villages plutôt que des villes sur la plus grande partie de la bande, les centres régionaux étant en retrait de la ligne. Gyumri et les villes du nord de l’Arménie font face à la frontière turque fermée plutôt qu’à la frontière azerbaïdjanaise ; au sud, les localités du Syunik se trouvent sur la route qui relie l’Arménie à l’Iran.
Portée opérationnelle générale
Three effects. First, the boundary was an internal Soviet administrative line until 1991 and was never surveyed to international standards, so there is genuinely no agreed line to police — the incidents that recur along it are a product of that ambiguity rather than of any decision. Second, because settlements sit close to and below the line, delimitation has direct consequences for specific communities' land, water and road access, which is why the 2024 Tavush transfer was politically costly out of proportion to its size. Third, the southern convergence around Syunik makes the transport question inseparable from the border question: any route to Nakhchivan crosses the narrowest and most sensitive ground on the frontier, within a short distance of Iran.
Observé
Incidents along undelimited sections have recurred since the 1990s and continued after 2020, including exchanges in the northern sections. A first delimitation of roughly a dozen kilometres in the Tavush direction was completed in 2024, involving the transfer of four villages to Azerbaijani control and requiring practical arrangements for a road and for water access. Delimitation has not extended substantially beyond that section.
Évalué
Treating the delimitation problem as primarily political understates how much of it is cartographic and practical. Where the line has been agreed, it was agreed village by village with arrangements for roads and water — which suggests the process is workable and slow rather than blocked, and that its pace is a function of local complexity as much as of the wider negotiation.

Pertinence pour les campagnes
Ce qui reste inconnu
- Incident reports along the boundary come from the parties and are not independently verified; accounts of sequence and responsibility routinely differ.
- No agreed map of the boundary exists for most of its length, which is the underlying fact this record describes.
- Current positions and force levels along the line are not published by this module and are not the basis of any claim here.
- The technical arrangements agreed in the 2024 delimitation are described in outline by both governments rather than published in full.
Incidents le long des sections non délimitées
Signalés par les deux parties et non vérifiés de manière indépendante. Leur fréquence et le fait qu’ils fassent ou non des victimes sont les mesures observables.
Arrangements pratiques autour des zones remises
L’accès routier et l’approvisionnement en eau constituaient la substance de la remise du Tavush. Leur fonctionnement est le test permettant de savoir si le modèle peut être étendu.
