Do transboundary and transnational properties promote international cooperation and representativity?

In the spirit of the 1945 UNESCO Constitution, the World Heritage Committee strives to promote international cooperation. It is evident in the Committee’s support of transboundary* and transnational** properties as tools for encouraging international cooperation and improved representation of state parties and heritage themes. Thus, international cooperation does not merely aid heritage protection but also endorses UNESCO’s intents to foster ‘intellectual and moral solidarity of mankind‘ and to boost the 2030 Agenda of Sustainable Development Goals.

The presentation will analyze transboundary and transnational properties on the World Heritage List and present their inscription trends and characteristics to examine whether they succeed in promoting cooperation and diversity. Our analysis will address four indicative aspects – the participants (i.e., the involved state parties and global regions); the inscription trends; heritage types (natural versus cultural); and lastly property types (transboundary versus transnational).

Our findings demonstrate a clear shift from natural transboundary properties in the 1980’s and 1990’s to cultural transnational properties in the last two decades. We will argue that despite the aspiration to promote international cooperation and improve representativity, most resulting inscriptions correspond to existing trends and inclines on the List, e.g., the dominance of the European/North American region. To conclude, we will address the proposed Erich Mendelsohn’s nomination considering our investigation.

* Transboundary property - a continuous area which extends across the borders of neighboring countries.

** Transnational property - a series of components located in the territory of different countries.
