The European Landscape Convention (ELC) was initiated by the Council of Europe in 2000 and entered into force in 2004. It serves as a legal treaty defining the protection and development of European intergovernmental cooperation in landscape-related issues. The present contribution accordingly deals with the basic features of the ELC and the underlying (multiple) understandings of landscape, which are composed of essentialist, positivist, and (moderate) constructivist perspectives, and asks about the associated implications. Furthermore, this looks at its implementation and deals with the question of why, for example, Germany still has (as of 2023) neither ratified nor signed the ELC. Despite significant criticism, for example, regarding its basic conception, its lack of legal operationalization, etc., it holds the potential of an interface that strengthens a diversity of approaches to landscape(s) recognized as legitimate in terms of theory, methodology, and especially lifeworld orientation.
