Blue border
The blue border is the course of a political border on the water. The expression corresponds to the term green border for the boundaries in terrain between the land border border crossings .
Along with mountain ridges , the blue borders in the interior of the country belong to the historically important natural borders that have been politically consolidated. The term is used both for rivers that mark the borderline and also for lakes and seas , and both for the bilateral sea border ( sea border of the coastal waters ), but also generally for the other possible sovereign claims according to international maritime law up to 200 miles -Zone and possibly the international waters of the high seas . In contrast to rivers, where there are usually border crossings at bridges and which are comparatively easy to control, sea borders are long sections, often without a defined or with a transition that has not yet been finally clarified, and only very laboriously monitored.
The term has become particularly important in the discussions about the refugee crisis in Europe : Europe's great "blue border" and Schengen external border of the European Union is - in addition to the open Atlantic and North Sea - the Mediterranean , through which a large part of immigration to the EU at times takes place, and on which many thousands of people have drowned since the 2000s.
