World Heritage Site

World Heritage Sites are landmarks and areas with legal protection under an international treaty administered by UNESCO for having cultural, historical, or scientific significance. The sites are judged to contain "cultural and natural heritage around the world considered to be of outstanding value to humanity".^[2]

\n"}">

To be selected, a World Heritage Site is nominated by its host country and determined by the UNESCO's World Heritage Committee to be a unique landmark which is geographically and historically identifiable, having a special cultural or physical significance, and to be under a sufficient system of legal protection. For example, World Heritage Sites might be ancient ruins or historical structures, buildings, cities,^[a] deserts, forests, islands, lakes, monuments, mountains or wilderness areas.^[5][6]

A World Heritage Site may signify a remarkable accomplishment of humankind and serve as evidence of our intellectual history on the planet, or it might be a place of great natural beauty.^[7] As of July 2024, a total of 1,223 World Heritage Sites (952 cultural, 231 natural and 40 mixed cultural and natural properties) exist across 168 countries. With 60 selected areas, Italy is the country with the most sites, followed by China with 59, and Germany with 54.^[8]

The sites are intended for practical conservation for posterity, which otherwise would be subject to risk from human or animal trespassing, unmonitored, uncontrolled or unrestricted access, or threat from local administrative negligence. Sites are demarcated by UNESCO as protected zones.^[2] The World Heritage Sites list is maintained by the international World Heritage Program administered by the UNESCO World Heritage Committee, composed of 21 "states parties" that are elected by the United Nations General Assembly, and advised by reviews of international panels of experts in natural or cultural history, and education.^[9]

The Program catalogues, names, and conserves sites of outstanding cultural or natural importance to the common culture and heritage of humankind. The programme began with the Convention Concerning the Protection of the World Cultural and Natural Heritage,^[10] which was adopted by the General Conference of UNESCO on 16 November 1972. Since then, 196 states have ratified the convention,^[11] making it one of the most widely recognised international agreements and the world's most popular cultural programme.^[12]

By assigning places as World Heritage Sites, UNESCO wants to help preserve them for future generations. Its motivation is that "heritage is our legacy from the past, what we live with today" and that both cultural and natural heritage are "irreplaceable sources of life and inspiration".^[2] UNESCO's mission with respect to World Heritage consists of eight sub targets. These include encouraging the commitment of countries and local population to World Heritage conservation in various ways, providing emergency assistance for sites in danger, offering technical assistance and professional training, and supporting States Parties' public awareness-building activities.^[2]

Being listed as a World Heritage Site can positively affect the site, its environment, and interactions between them. A listed site gains international recognition and legal protection, and can obtain funds from, among others, the World Heritage Fund to facilitate its conservation under certain conditions.^[18] UNESCO reckons the restorations of the following four sites among its success stories: Angkor in Cambodia, the Old City of Dubrovnik in Croatia, the Wieliczka Salt Mine near Kraków in Poland, and the Ngorongoro Conservation Area in Tanzania.^[19] Additionally, the local population around a site may benefit from significantly increased tourism revenue.^[20] When there are significant interactions between people and the natural environment, these can be recognised as "cultural landscapes".^[b]

A country must first identify its significant cultural and natural sites in a document known as the Tentative List. Next, it can place sites selected from that list into a Nomination File, which is evaluated by the International Council on Monuments and Sites and the World Conservation Union. A country may not nominate sites that have not been first included on its Tentative List. The two international bodies make recommendations to the World Heritage Committee for new designations. The Committee meets once a year to determine which nominated properties to add to the World Heritage List; sometimes it defers its decision or requests more information from the country that nominated the site. There are ten selection criteria – a site must meet at least one to be included on the list.^[21]

Until 2004, there were six sets of criteria for cultural heritage and four for natural heritage. In 2005, UNESCO modified these and now has one set of ten criteria. Nominated sites must be of "outstanding universal value" and must meet at least one of the ten criteria.^[7]

Cultural

1. "To represent a masterpiece of human creative genius"
2. "To 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"
3. "To bear a unique or at least exceptional testimony to a cultural tradition or to a civilization which is living, or which has disappeared"
4. "To be an outstanding example of a type of building, architectural or technological ensemble or landscape which illustrates (a) significant stage(s) in human history"
5. "To 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"
6. "To be directly or tangibly associated with events or living traditions, with ideas, or with beliefs, with artistic and literary works of outstanding universal significance"^[c]

Natural

7. "To contain superlative natural phenomena or areas of exceptional natural beauty and aesthetic importance"
8. "To 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"
9. "To be outstanding examples representing significant on-going ecological and biological processes in the evolution and development of terrestrial, fresh water, coastal and marine ecosystems and communities of plants and animals"
10. "To 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"
^[7]

A country may request to extend or reduce the boundaries, modify the official name, or change the selection criteria of one of its already listed sites. Any proposal for a significant boundary change or to modify the site's selection criteria must be submitted as if it were a new nomination, including first placing it on the Tentative List and then onto the Nomination File.^[21]

A request for a minor boundary change, one that does not have a significant impact on the extent of the property or affect its "outstanding universal value", is also evaluated by the advisory bodies before being sent to the committee. Such proposals can be rejected by either the advisory bodies or the Committee if they judge it to be a significant change instead of a minor one.^[21] Proposals to change a site's official name are sent directly to the committee.^[21]

A site may be added to the List of World Heritage in Danger if conditions threaten the characteristics for which the landmark or area was inscribed on the World Heritage List. Such problems may involve armed conflict and war, natural disasters, pollution, poaching, or uncontrolled urbanisation or human development. This danger list is intended to increase international awareness of the threats and to encourage counteractive measures. Threats to a site can be either proven imminent threats or potential dangers that could have adverse effects on a site.^[22]

The state of conservation for each site on the danger list is reviewed yearly; after this, the Committee may request additional measures, delete the property from the list if the threats have ceased or consider deletion from both the List of World Heritage in Danger and the World Heritage List.^[21] Only three sites have ever been delisted: the Arabian Oryx Sanctuary in Oman, the Dresden Elbe Valley in Germany, and the Liverpool Maritime Mercantile City in the United Kingdom.^{[citation needed]}

The Arabian Oryx Sanctuary was directly delisted in 2007, instead of first being put on the danger list, after the Omani government decided to reduce the protected area's size by 90%.^[23] The Dresden Elbe Valley was first placed on the danger list in 2006 when the World Heritage Committee decided that plans to construct the Waldschlösschen Bridge would significantly alter the valley's landscape. In response, the Dresden City Council attempted to stop the bridge's construction. However, after several court decisions allowed the building of the bridge to proceed, the valley was removed from the World Heritage List in 2009.^[24] Liverpool's World Heritage status was revoked in July 2021, following developments (Liverpool Waters and Bramley-Moore Dock Stadium) on the northern docks of the World Heritage site leading to the "irreversible loss of attributes" on the site.^[25][26]

The first global assessment to quantitatively measure threats to Natural World Heritage Sites found that 63% of sites have been damaged by increasing human pressures including encroaching roads, agriculture infrastructure and settlements over the last two decades.^[27][28] These activities endanger Natural World Heritage Sites and could compromise their unique values. Of the Natural World Heritage Sites that contain forest, 91% experienced some loss since 2000. Many of them are more threatened than previously thought and require immediate conservation action.^[27]

The destruction of cultural assets and identity-establishing sites is one of the primary goals of modern asymmetrical warfare. Terrorists, rebels, and mercenary armies deliberately smash archaeological sites, sacred and secular monuments and loot libraries, archives and museums. The UN, United Nations peacekeeping and UNESCO in cooperation with Blue Shield International are active in preventing such acts. "No strike lists" are also created to protect cultural assets from air strikes.^{[29][30][31][32]}

The founding president of Blue Shield International Karl von Habsburg summed it up with the words: "Without the local community and without the local participants, that would be completely impossible".^[33][34]

The UNESCO-administered project has attracted criticism. This was caused by perceived under-representation of heritage sites outside Europe, disputed decisions on site selection and adverse impact of mass tourism on sites unable to manage rapid growth in visitor numbers.^[35][36] A large lobbying industry has grown around the awards, because World Heritage listing can significantly increase tourism returns. Site listing bids are often lengthy and costly, putting poorer countries at a disadvantage. Eritrea's efforts to promote Asmara are one example.^[37]

In 2016, the Australian government was reported to have successfully lobbied for the World Heritage Site Great Barrier Reef^[38] conservation efforts to be removed from a UNESCO report titled "World Heritage and Tourism in a Changing Climate". The Australian government's actions, involving considerable expense for lobbying and visits for diplomats, were in response to their concern about the negative impact that an "at risk" label could have on tourism revenue at a previously designated UNESCO World Heritage Site.^[39][40]

In 2021, international scientists recommended UNESCO to put the Great Barrier Reef on the endangered list,^[41] as global climate change had caused a further negative state of the corals and water quality.^[42] Again, the Australian government campaigned against this, and in July 2021, the World Heritage Committee, made up of diplomatic representatives of 21 countries, ignored UNESCO's assessment, based on studies of scientists, "that the reef was clearly in danger from climate change and so should be placed on the list." According to environmental protection groups, this "decision was a victory for cynical lobbying and [...] Australia, as custodians of the world's biggest coral reef, was now on probation."^[43]

Several listed locations, such as Casco Viejo in Panama and Hội An in Vietnam, have struggled to strike a balance between the economic benefits of catering to greatly increased visitor numbers after the recognition and preserving the original culture and local communities.^[20][44]

Another criticism is that there is a homogeneity to these sites, which contain similar styles, visitor centres, etc., meaning that a lot of the individuality of these sites has been removed to become more attractive to tourists.^[45]

Anthropologist Jasper Chalcraft said that World Heritage recognition often ignores contemporary local usage of certain sites. This leads to conflicts on the local level which can result in the site being damaged. Rock art under world heritage protection at the Tadrart Acacus in Libya have occasionally been intentionally destroyed. Chalcraft links this destruction to Libyan national authorities prioritizing World Heritage status over local sensibilities by limiting access to the sites without consulting with the local population.^[46]

UNESCO has also been criticized for alleged geographic bias, racism, and colourism in world heritage inscription. A major chunk of all world heritage inscriptions are located in regions whose populations generally have lighter skin, including Europe, East Asia, and North America.^{[47][48][49][50]}

The World Heritage Committee has divided the world into five geographic regions: Africa, Arab states, Asia and the Pacific, Europe and North America, and Latin America and the Caribbean. Russia and the Caucasus states are classified as European, while Mexico and the Caribbean are classified as belonging to the Latin America and the Caribbean region. The UNESCO geographic regions also give greater emphasis on administrative, rather than geographic associations. Hence, Gough Island, located in the South Atlantic, is part of the Europe and North America region because the British government nominated the site.

The table below includes a breakdown of the sites according to these regions and their classification as of July 2024^[update]:^[8][51]
