What category of border dispute involves disagreements over administrative control, such as regulating cross-border movement or resource sharing?

The question asks to identify the category of border dispute that relates to disagreements over administrative control, such as the regulation of cross-border movement or resource sharing.

Let's examine the given options:

• Positional dispute: This type of dispute arises from the interpretation of the border's location as described in treaties or maps. The general existence of the border is accepted, but its precise placement is contested.
• Delimitation dispute: This involves disagreements over the actual drawing of the border line on a map (delimitation) or its physical marking on the ground (demarcation).
• Territorial dispute: This is a fundamental disagreement over the ownership or sovereignty of a specific piece of land.
• Functional dispute: This type of dispute concerns the management of the border and the activities that cross it. It involves issues like the regulation of cross-border movement of people or goods, sharing of resources that straddle the border (e.g., water, oil), or environmental management.

The description in the question—"disagreements over administrative control, such as the regulation of cross-border movement or resource sharing"—directly aligns with the definition of a functional dispute. These disputes are about how the border functions and how activities across it are managed, rather than its location or ownership.

The correct answer is Functional dispute.
