delimitation ‘It is common practice to distinguish delimitation and demarcation of a
boundary. The former denotes description of the alignment in a treaty or other written
source, or by means of a line marked on a map or chart. Demarcation denotes the means by
which the described alignment is noted, or evidenced, on the ground, by means of cairns
of stones, concrete pillars, beacons of various kinds, cleared roads in scrub, and so on. The
principle of the distinction is clear enough, but the usage of the draftsman of the particular
international agreement or political spokesman may not be consistent. In fact the terms
are sometimes used to mean the same thing’: Brownlie, African Boundaries. A Legal and
Diplomatic Encyclopaedia ( 1979 ).
