5. Border disputes and territorial integrity: Borders define a nation's territorial integrity and can be a subject of potential disputes. Monitoring borders helps countries protect and defend their sovereign territory, preventing encroachments or unauthorized activities that could jeopardize their sovereignty. Overall, monitoring borders helps countries maintain national security, preserve public safety, regulate immigration, facilitate legal trade, protect public health, and uphold their territorial integrity. It contributes to the overall stability and well-being of the nation and its people.
