The World Heritage Convention
The UNESCO Convention Concerning the Protection of the World Cultural and Natural Heritage – the – recognizes the importance of both natural and cultural heritage properties, as well as the imperative to protect and conserve them in a rapidly changing world. While pledge to conserve all heritage within their territories, the best-known element of the Convention is the World Heritage List of those natural and cultural heritage places that are considered to be of ‘Outstanding Universal Value’. To be included on the List, properties must meet at least one of ten criteria of Outstanding Universal Value (Box 3.1), along with requirements for authenticity, integrity, and protection and management (see Box 3.2). There are many different kinds of World Heritage properties, both natural and cultural: places where geological features or processes can be seen, natural and cultural landscapes, ecosystems and natural habitats, architectural complexes, human settlements, archaeological sites, industrial heritage, sacred places, heritage routes and many others. They may also have associated intangible attributes, such as important spiritual practices or related cultural traditions, which are reflected in physical elements of the property.
The wide variety of heritage around the world means that the impacts which can affect World Heritage properties are equally diverse. For example: upstream drainage works that affect water levels at a freshwater site; large buildings that affect views in and out of a ; incremental changes to an urban layout that was representative of a historical period; blockage of a migration route for an important species; or any development on a site whose pristine characteristics are central to an important cultural tradition. is a key tool for identifying, avoiding and minimizing such negative impacts.
The
established a World Heritage Committee, an intergovernmental body composed of
which maintains the World Heritage List. The Convention is also supported by a Secretariat within UNESCO, known as the UNESCO
. Three international organizations are named as
to the World Heritage Committee in Article 8.3 of the Convention: ICCROM, ICOMOS and IUCN. The World Heritage Committee meets annually to oversee and guide the implementation of the Convention. This includes deciding which properties are inscribed on, or deleted from the World Heritage List. The Committee also examines reports on the state of conservation of properties inscribed on the World Heritage List and may request
to take action when a specific issue affects a property – this can include a request for an impact assessment. Indeed, Committee Decision 39 COM 7 underlined the benefit to
of using impact assessments to manage continuity and change, and encouraged them to integrate impact assessment processes into legislation, planning mechanisms and management planning.
Box 3.1. Criteria for Outstanding Universal Value
The property should:
i. represent a masterpiece of human creative genius;
ii. exhibit an important interchange of human values, over a span of time or within a cultural area of the world, on developments in architecture or technology, monumental arts, town-planning or landscape design;
iii. bear a unique or at least exceptional testimony to a cultural tradition or to a civilization which is living or which has disappeared;
iv. be an outstanding example of a type of building, architectural or technological ensemble or landscape which illustrates (a) significant stage(s) in human history;
v. be an outstanding example of a traditional human settlement, land-use, or sea-use which is representative of a culture (or cultures), or human interaction with the environment especially when it has become vulnerable under the impact of irreversible change;
vi. be directly or tangibly associated with events or living traditions, with ideas, or with beliefs, with artistic and literary works of outstanding universal significance. (The Committee considers that this criterion should preferably be used in conjunction with other criteria);
vii. contain superlative natural phenomena or areas of exceptional natural beauty and aesthetic importance;
viii. be outstanding examples representing major stages of earth’s history, including the record of life, significant on-going geological processes in the development of landforms, or significant geomorphic or physiographic features;
ix. be outstanding examples representing significant on-going ecological and biological processes in the evolution and development of terrestrial, freshwater, coastal and marine ecosystems and communities of plants and animals; and/or
x. contain the most important and significant natural habitats for in-situ conservation of biological diversity, including those containing threatened species of Outstanding Universal Value from the point of view of science or conservation.

Box 3.2
, integrity, protection and management
applies to cultural heritage, and refers to the degree to which knowledge and understanding of the property’s heritage values are understood and believed to be credible: whether their cultural values are truthfully and credibly expressed through attributes including form and design; materials and substance; use and function; traditions, techniques and management systems; location and setting; language and other forms of intangible heritage; spirit and feeling; and other internal and external factors.
is a measure of the wholeness and intactness of the natural and/or cultural heritage and its attributes: the extent to which the property includes all elements necessary to express its Outstanding Universal Value; whether it is of adequate size to ensure the complete representation of the features and processes which convey the property’s significance; and whether it has been protected from adverse effects of development and/or neglect.
Protection and management relates to how a property’s Outstanding Universal Value, including its integrity and/or authenticity, are sustained and enhanced over time.
