Regional aid border of the State of Brandenburg

The regional aid border covers the Länder of Berlin and Brandenburg and determines the area on which agricultural support is coordinated by these two countries. It serves to coordinate the demarcation between the states of Brandenburg, Saxony, Saxony-Anhalt and Mecklenburg-Western Pomerania, which is valid for land-related agricultural support. It is not necessary to define a regional aid border different from the national border with Lower Saxony, as this border is formed by the Elbe.
