Disclave
A disclave is a territory which is geographically separated from the main part of the state or entity to which it belongs and is entirely surrounded by the territory of another entity. It differs from an exclave, which only needs to be accessible from its parent territory by traversing international waters or airspace. A disclave requires complete terrestrial encirclement.
Put simply, a disclave is an exclave that is also an enclave. This dual nature makes it a unique geopolitical situation.
The practical implications of a disclave can vary greatly. They can pose logistical challenges for the governing entity, impacting infrastructure, service delivery, and security. They can also be points of diplomatic complexity, requiring agreements with the surrounding territory to ensure the movement of people and goods. The inhabitants of a disclave might face unique economic, social, and political realities due to their isolated position. The ease of access to the "host" territory may significantly impact the well-being of the inhabitants.
