The UNESCO Convention Concerning the Protection of the World Cultural and Natural Heritage – the World Heritage Convention The Convention Concerning the Protection of the World Cultural and Natural Heritage is an international treaty adopted by the UN in 1972 that defines the kind of natural or cultural sites which can be considered for inscription on the World Heritage List for their Outstanding Universal Value for all humankind. Commonly known as the World Heritage Convention, it establishes how the international community as a whole is responsible for
the protection of such heritage and sets out the duties of States Parties in identifying potential sites that may be eligible for inscription onto the World Heritage List and their role in protecting and preserving them. By signing the Convention, each country pledges to conserve not only the sites situated on its territory that have been recognized as being of Outstanding Universal Value, but also to protect its national heritage and to be involved in international efforts to protect, conserve and promote the heritage of humankind.
– 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 States Parties The countries which have adhered to the Convention Concerning the Protection of the World Cultural and Natural Heritage ( World Heritage Convention The Convention Concerning the Protection of the World Cultural and Natural Heritage is an international treaty adopted by the UN in 1972 that defines the kind of natural or cultural sites which can be considered for inscription on the World Heritage List for their Outstanding Universal Value for all humankind.

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 World Heritage property A cultural, natural or mixed heritage place inscribed on the World Heritage List and therefore considered to be of OUV for humanity. The responsibility for nominating a property to the World Heritage List falls upon the State(s) Party(ies) where it is located. The World Heritage Committee decides whether a property should be inscribed on the World Heritage List, taking into account the technical recommendations of the Advisory Bodies following rigorous evaluation processes.
When used as a general term, World Heritage refers to all the natural, cultural and mixed properties inscribed on the World Heritage List.
; 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. Impact assessment Impact assessment is the process of identifying, predicting and evaluating the potential environmental impacts of proposed actions prior to major approval decisions being taken and commitments made. It is undertaken for the purpose of avoiding or mitigating adverse impacts, and enhancing beneficial impacts. More generally, impact assessment can be appreciated as a way of thinking and planning that can be applied to all scales of activity. Impact assessment can be applied to development proposals at various levels – projects, plans, programmes and policies.

is a key tool for identifying, avoiding and minimizing such negative impacts.

Integrity All properties nominated for inscription on the World Heritage List shall satisfy the conditions of integrity. Integrity is a measure of the wholeness and intactness of the natural and/or cultural heritage and its attributes. Examining the conditions of integrity therefore requires assessing the extent to which the property:

c. suffers from adverse effects of development and/or neglect
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.
