Paragraph 183

“When considering the inscription of a property on the List of World Heritage in Danger, the Committee shall develop, and adopt, as far as possible, in consultation with the State Party concerned, a Desired state of conservation for the removal of the property from the List of World Heritage in Danger, and a programme for corrective measures.”[1]


[1]           In relation to the paragraph 183 of the Operational Guidelines, there are several decisions from different properties related to the desired state of conservation. See for example 31 COM 7A.16, 31 COM 7A.21, 36 COM 7A.34, 36 COM 7B.102, 37 COM 7A.40, 38 COM 7A.23, 39 COM 7A.13, 39 COM 7A.18, 41 COM 7A.19, 41 COM 7A.23.

Paragraph 192

“The Committee adopted the following procedure for the deletion of properties from the World Heritage List in cases:

a) where the property has deteriorated to the extent that it has lost those characteristics which determined its inclusion in the World Heritage List; and

b) where the intrinsic qualities of a World Heritage site were already threatened at the time of its nomination by human action and where the necessary corrective measures as outlined by the State Party at the time, have not been taken within the time proposed (…)”.

"21. [The World Heritage Committee] (u)rges States Parties, with the support of the World Heritage Centre and the Advisory Bodies, to:
a) Incorporate well-designed buffer zones based on a holistic understanding of natural as well as human induced factors affecting the property, supported by reinforcing relevant legal, policy, awareness and incentive mechanisms, into new nominations and where appropriate into existing properties to ensure enhanced protection of World Heritage properties,
b) Place particular emphasis on strategic environmental assessment and impact assessments for potential projects within buffer zones to avoid, negative impacts on OUV from developments and activities in these zones,
c) Develop buffer zone protection and management regimes that optimize the capture and sharing of benefits to communities to support the aspirations of the 2015 Policy for the integration of a Sustainable Development Perspective into the processes of the World Heritage Convention,
d) Ensure buffer zones are supported by appropriate protection and management regimes in line with the property’s OUV, that build connectivity with the wider setting in cultural, environmental and landscape terms."

Paragraph 172

“The World Heritage Committee invites the States Parties to the Convention to inform the Committee, through the Secretariat, of their intention to undertake or to authorize in an area protected under the Convention major restorations or new constructions which may affect the Outstanding Universal Value of the property.  Notice should be given as soon as possible (…) and before making any decisions that would be difficult to reverse, so that the Committee may assist in seeking appropriate solutions to ensure that the Outstanding Universal Value of the property is fully preserved.”

"30. [The World Heritage Committee] notes that the pressures on historic urban areas arising from inappropriate or inconsistent development controls, rapid, uncontrolled and planned development, including large development projects, additions that are incompatible in their volume, mass tourism, as well as the accumulated impact of incremental changes have continued within numerous World Heritage properties and in their buffer zones and settings, and considers that these present potential and actual major threats to the Outstanding Universal Value (OUV) of properties, including their integrity and authenticity, as well as increasing their vulnerability to disasters, including those resulting from climate change;
(…)
34. [The World Heritage Committee] (s)tresses the importance of carrying out Heritage Impact Assessments to evaluate and thereby avoid or manage potential threats to the OUV of the property arising from new urban development projects."

Conclusions. “The following are [the] key principles:

i. in addressing the impacts of climate change on the outstanding universal value, integrity and authenticity of World Heritage properties, the World Heritage community will work in cooperation with other partners that also have responsibility, resources and expertise related to this challenge.

ii. The World Heritage Committee will be an advocate for relevant climate change research, and work to influence and support partners that are mandated and resourced to carry out such research.

iii. World Heritage properties will be used wherever appropriate and possible as a means to raise awareness about the impacts of climate change upon World Heritage to act as a catalyst in the international debate and obtain support for policies to mitigate climate change, and to communicate best practices in vulnerability assessments, adaptation strategies, mitigation opportunities, and pilot projects.

iv. Climate change will be considered in all aspects of nominating, managing, monitoring and reporting on the status of these properties.

v. In considering the threat posed by climate change to the OUV, authenticity and/or integrity of a World Heritage property, the World Heritage Committee will use the existing tools and processes”.

11. “The potential impacts of Climate Change range from physical, to social and cultural aspects. (…). Experience and lessons learned on addressing Climate Change impacts stress the need for using a number of management responses at national and local levels. The World Heritage Convention provides an opportunity to develop strategies to implement relevant actions in respect of cultural and natural heritage properties threatened by Climate Change. Given the complexity of this issue, States Parties may request guidance from the World Heritage Committee to implement appropriate management responses to face the threats posed by Climate Change on their natural and cultural properties inscribed on the World Heritage List”.

13. “Conservation is the management of change, and Climate Change is one of the most significant global challenges facing society and the environment today. The actions that need to be taken to safeguard heritage are threefold:

  • Preventive actions: monitoring, reporting and mitigation of Climate Change effects through environmentally sound choices and decisions at a range of levels: individual, community, institutional and corporate.

  • Corrective actions: adaptation to the reality of Climate Change through global and regional strategies and local management plans.

  • Sharing knowledge: including best practices, research, communication, public and political support, education and training, capacity building, networking, etc.”

15. “It is noteworthy that there are strong links between natural and cultural heritage and the Climate Change issue could be used as an opportunity for the two parts of the Convention to be brought closer together”.

16. “(…) Climate Change is one risk among a number of challenges facing World Heritage sites. This threat should be considered in the broader context of the conservation of these sites”.

5. "[The World Heritage Committee] notes that the impacts of climate change are affecting many and are likely to affect many more World Heritage properties, both natural and cultural in the years to come;

6. Encourages all States Parties to seriously consider the potential impacts of climate change within their management planning, in particular with monitoring, and risk preparedness strategies, and to take early action in response to these potential impacts;

10. Strongly encourages States Parties and the Advisory Bodies to use the network of World Heritage properties to highlight the threats posed by climate change to natural and cultural heritage, start identifying the properties under most serious threats, and also use the network to demonstrate management actions that need to be taken to meet such threats, both within the properties and in their wider context;

11. Also encourages UNESCO to do its utmost to ensure that the results about climate change affecting World Heritage properties reach the public at large, in order to mobilize political support for activities against climate change and to safeguard in this way the livelihood of the poorest people of our planet."
