The essence of a national boundary is separate the ‘self' from the ‘other'. Thus natural boundaries, like all institutions have their own set of internal rules which govern their behaviour, and interestingly enough we find that much of their behaviour become self perpetuating and resistant to change. Border institutions govern the extent of inclusion and exclusion; the degree of permeability and the laws governing in both sides of natural boundaries. Since institutions are self perpetuating and resistant to change, it often requires increase in the Rules of trans-national boundary interaction on the grounds of norms and regulations to undergo any formed process of change. Most studies in this area have focused on the public policies relating to it and their management mechanism.
The policy process here focuses on two broad frameworks. First, there is a delineation of new concepts and ideas relating to national boundaries which have not been part of the traditional studies, in particular, notions of inclusion, exclusion nongeographic boundaries, and management their of as institutions. Secondly, reinterpretation of existing policy frameworks to adapt to the new situation, such as, historic evolutions notions of borders as well as the complex processes determining paths to different policy mixes.
