“Although buffer zones are not part of the nominated property, any modifications to or creation of buffer zones subsequent to inscription of a property on the World Heritage List should be approved by the World Heritage Committee using the procedure for a minor boundary modification (see paragraph 164 and Annex 11). The creation of buffer zones subsequent to inscription is normally considered to be a minor boundary modification.”
“Cultural landscapes are cultural properties and represent the "combined works of nature and of man" designated in Article 1 of the Convention. They are illustrative of the evolution of human society and settlement over time, under the influence of the physical constraints and/or opportunities presented by their natural environment and of successive social, economic and cultural forces, both external and internal.”
7. “[Cultural Landscapes] … should be selected on the basis both of their Outstanding Universal Value and of their representativity in terms of a clearly defined geo‑cultural region and also for their capacity to illustrate the essential and distinct cultural elements of such regions”.
9. “Cultural landscapes often reflect specific techniques of sustainable land‑use, considering the characteristics and limits of the natural environment they are established in, and a specific spiritual relation to nature. Protection of cultural landscapes can contribute to modern techniques of sustainable land‑use and can maintain or enhance natural values in the landscape. The continued existence of traditional forms of land‑use supports biological diversity in many regions of the world”.
The World Heritage committee recommends addressing landscape surveys and the historic evolution of the landscape, as a holistic reflection of history and cultural traditions and of the interaction between culture and nature, including the way the landscape has been shaped by human practices and natural resources (based on Case law on decisions on Nominations).
