Geographic barriers are limits agreed and established among neighbor nations to delimit their territory.  A boundary is a división, whether symbolic or physic a geographic barrier defines where a country begins and where another end. Also known as “ frontiers” in cases where an actual barrier like a fence or a wall differentiates the surrounding Territoires.  For any empire, these definitory limits represent wealthiness, for the population, cultural, political and socio-economical definition of production and therefore, sustainability and also power through a diversity of resources. Territorialization- implicit in these barriers- also means identity for the population and the governments who rules inside of those limits.

an informal structure in a bureaucracy would be something like so-called "office politics". where there's a formal structure set up for the organization, but then an informal subculture as well that has a way of organizing the bureaucracy further. this can be positive because it sets up an added degree of organization, albeit informal, within the bureaucracy.
