The World Heritage Convention, revolutionary in its conception thirty years ago, has today become the most widely accepted international legal instrument for the protection of cultural and natural heritage. Now, however, it requires adjustments if its successful implementation is to continue. These changes must not modify the Convention but must achieve an equivalent level of implementation. This article focuses on three issues, which are currently the subject of ongoing discussions: the representivity of the World Heritage List, equitable representation in the World Heritage Committee, and revision of the Operational Guidelines. The author not only describes the procedures for reform and the results achieved so far, but he also compares the legal provisions of this Convention to the other international legal instruments for the protection of cultural heritage.
