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. 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. In 2016, the Australian government was reported to have successfully lobbied for the World Heritage Site
Great Barrier Reef 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. In 2021, international scientists recommended UNESCO to put the Great Barrier Reef on the endangered list, as global
climate change had caused a further negative state of the corals and water quality. 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." 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. 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. 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. 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. ==Statistics==
