A geopark is a protected area with internationally significant geology within which sustainable development is sought and which includes tourism, conservation, education and research concerning not just geology but other relevant sciences. In 2005, a European Geopark was defined as being: "a territory with a particular geological heritage and with a sustainable territorial development....the ultimate aim of a European Geopark is to bring enhanced employment opportunities for the people who live there." Today the geopark is virtually synonymous with the UNESCO geopark, which is defined and managed under the voluntary authority of UNESCO's International Geoscience and Geoparks Programme (IGGP). UNESCO provides a standard for geoparks and a certification service to parks that apply for it. The service is available to member states of UNESCO. This list is not the same as the member states of the United Nations. Membership in the UN does not automatically imply membership in UNESCO, even though UNESCO is part of the UN. Both lists have about 193 member nations, but not exactly the same 193. The UN list covers most of the geopolitical world, but the UNESCO list notably lacks the United States and Israel, which resigned in 2018 because they believed UNESCO is anti-Israel. As geoparks are only available to UNESCO member nations, there are no geoparks in US territory. The UNESCO Global Geoparks Network co-ordinates the activities of the many UNESCO Global Geoparks (UGGp's) around the world. It is divided into regional networks, such as the European Geoparks Network. The EGN historically preceded the UGGN, being founded in 2000 with the first four geoparks. It joined with UNESCO in 2001 and in 2005 agreed in the Madonie Declaration to be a regional network of the UGGps, which had been created by UNESCO in 2004. The Madonie Declaration of 2004, which was signed by Nikolas Zouros for the EGN and Wolfgang Eder for UNESCO, established what was later called a "bottom up" system of precedence. An applicant geopark must first be a member of the EGN before applying to the UGGN. Furthermore, another level was created, the National Geoparks Network, which at first glance seems a contradiction in terms. Geoparks are international. What the Declaration meant was, if a potentially international type of site (a possible geosite) existed within the candidate park's country, the park must belong to it before it can apply to the regional network. This type was dubbed an NGN. Its
