Jesus. In some cases, danger listing has sparked conservation efforts and prompted the release of funds, resulting in a positive development for sites such as the Galápagos Islands and Yellowstone National Park, both of which have subsequently been removed from the List of World Heritage in Danger. Despite this, the list itself and UNESCO's implementation of it have been the focus of criticism. In particular, States Parties and other stakeholders of World Heritage Sites have questioned the authority of the Committee to declare a site in danger without their consent. Until 1992, when UNESCO set a precedent by placing several sites on the danger list against their wishes, States Parties would have submitted a programme of corrective measures before a site could be listed. Instead of being used as intended, the List of World Heritage in Danger is perceived by some states as a black list and according to Christina Cameron, Professor at the School of Architecture, Canada Research Chair on Built Heritage, University of Montreal, has been used as political tool to get the attention of States Parties. The International Union for Conservation of Nature (IUCN) notes that UNESCO has referenced the List of World Heritage in Danger (without actually listing the site) in a number of cases where the threat could be easily addressed by the State Party. The Union also argues that keeping a site listed as endangered over a long period is questionable and that other mechanisms for conservation should be sought in these cases. , there are 53 entries (17 natural, 36 cultural) on the List of World Heritage in Danger. Arranged by the UNESCO regions, 21 of the listed sites are located in the Arab States (of which 6 are located in Syria and 5 in Libya), 16 in Africa (of which 5 are in the Democratic Republic of the Congo), 6 in Latin America and the Caribbean, 6 in Asia and the Pacific, and 4 in Europe and North America. The majority of the endangered natural sites (12) are located in Africa.
