“If a State Party wishes to request a minor modification to the boundaries of a property already on the World Heritage List, it must be prepared in compliance with the format of Annex 11 and must be received by 1 February by the Committee through the Secretariat, which will seek the evaluation of the relevant Advisory Bodies on whether this can be considered a minor modification or not. The Secretariat shall then submit the Advisory Bodies’ evaluation to the World Heritage Committee. The Committee may approve such a modification, or it may consider that the modification to the boundary is sufficiently significant as to constitute a significant boundary modification of the property, in which case the procedure for new nominations will apply.”
“Before States Parties begin to prepare a nomination of a property for inscription on the World Heritage List, they should become familiar with the nomination cycle, described in Paragraph 168. It is desirable to carry out initial preparatory work to establish that a property has the potential to justify Outstanding Universal Value, including integrity or authenticity, before the development of a full nomination dossier which could be expensive and time-consuming. Such preparatory work might include collection of available information on the property, thematic studies, scoping studies of the potential for demonstrating Outstanding Universal Value, including integrity or authenticity, or an initial comparative study of the property in its wider global or regional context, including an analysis in the context of the Gap Studies produced by the Advisory Bodies. This first phase of work will help to establish the feasibility of a possible nomination and avoid the use of resources on preparing nominations that may be unlikely to succeed. States Parties are encouraged to seek upstream advice from the relevant Advisory Body(ies) for this first phase as well as to contact the World Heritage Centre at the earliest opportunity in considering nominations to seek information and guidance.”
“Upstream Process: In relation to the nomination of sites for inscription on the World Heritage List, the “Upstream Process” comprises advice, consultation and analysis that occurs prior to the preparation of a nomination and is aimed at reducing the number of nominations that experience significant problems during the evaluation process. The basic principle of the Upstream Process is to enable the Advisory Bodies and the World Heritage Centre to provide guidance and capacity building directly to States Parties, throughout the whole process leading up to the preparation of a possible World Heritage nomination. For the upstream support to be effective, it should be undertaken from the earliest stage in the nomination process, at the moment of the preparation or revision of the States Parties’ Tentative Lists.
The purpose of the advice given in the context of a nomination is limited to providing guidance on the technical merit of the nomination and the technical framework needed, in order to offer the State(s) Party(ies) the essential tools that enable it(them) to assess the feasibility and/or actions necessary to prepare a possible nomination.
Requests for the Upstream Process shall be submitted using the official format (Annex 15 of the Operational Guidelines). Should the number of requests exceed the capacity, then the prioritization system as per paragraph 61.c will be applied.”
4. "[The World Heritage Committee] (…) recalls that, in order to be effective, the upstream support should ideally take place at an early stage, preferably at the moment of the preparation or revision of the States Parties’ Tentative Lists."
4. Encourages States Parties to integrate the notion of historic urban landscape in nomination proposals and in the elaboration of management plans of properties nominated for inscription on the World Heritage List;
5. Also encourages States Parties to integrate the principles expressed in the Vienna Memorandum into their heritage conservation policies;
6. Requests the Advisory Bodies and the World Heritage Centre to take into account the conservation of the historic urban landscape when reviewing any potential impact on the integrity of an existing World Heritage property, and during the nomination evaluation process of new sites."
