The international network seeks the membership
geoparks—geographical areas where geological heritage is the focus of local protection, education and development. A set of criteria as established by UNESCO Criteria satisfaction is evaluated during biennial meetings (every even year) by the Geoparks Committee, known as the
International Conference on Geoparks, which is also in charge with the periodic review of projects related to geological awareness. The first members of the GGN were named during the first conference in 2004, and it has continued to grow since then: The GGN works closely with another project under UNESCO's Ecological and Earth Sciences Division—the Man and Biosphere (MAB)
World Network of Biosphere Reserves—to come up with and establish different means of sustainable development in promoting the local communities’ relationship with the natural environment. ==Structure by continent and UNESCO region==
