IUCN is the global organisation with the longest consistent role in geoconservation
Geodiversity refers to the variety of the geological and physical elements of nature, such as minerals, rocks, soils, fossils and landforms, and active geological and geomorphological processes. Together with biodiversity, geodiversity constitutes the natural diversity of planet Earth.
IUCN’s advisory role on World Heritage and geodiversity
The 1972 UNESCO World Heritage Convention has recognised geodiversity from the outset of its work and is the longest standing global instrument for geodiversity conservation. As a founding organisation of the Convention and as its adviser on nature, IUCN has held the longest consistent role in geodiversity conservation science and practice of any global organisation.
IUCN evaluates new candidate sites proposed for the World Heritage List due to their natural “Outstanding Universal Value” (OUV), and monitors sites that have been included as World Heritage. One criterion for determining OUV is related to geoheritage – criterion (viii). Under this criterion, nominated sites shall:
“(viii) 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.” – Operational Guidelines for the Implementation of the World Heritage Convention
As of August 2017, there are 90 World Heritage sites currently listed under criterion (viii), including iconic places such as the Galapagos Islands, Yellowstone National Park, Swiss Alps Jungfrau-Aletsch, and the Namib Sand Sea. In undertaking its work on World Heritage, IUCN cooperates with a range of international specialist organisations focused on Earth Science, including the International Union of Geological Sciences, the International Association of Geomorphologists and the International Union of Speleology.
Related IUCN Resolutions and areas of work
IUCN’s interest in geodiversity management and in geoheritage conservation (known as geoconservation) has increased in the last decade.
IUCN Members, who include government and civil society organisations, have adopted resolutions in 2008, 2012 and 2016 calling on the global conservation community to support the protection and management of the world’s geodiversity and geoheritage.
WCC 2016 Res 083: Conservation of moveable geological heritage
WCC 2012 Res 048: Valuing and conserving geoheritage within the IUCN Programme 2013–2016
WCC 2008 RES 040: Conservation of geodiversity and geological heritage
Geodiversity and geoconservation are also relevant to IUCN policies and strategies, and contribute to many of IUCN’s areas of work such as: climate change, ecosystem management, environmental law, protected areas, science and knowledge, water, and World Heritage.
Geodiversity is an important consideration in the priorities set by the IUCN Programme 2017-2020. Geodiversity and geoconservation contribute to achieving the United Nations’ 2030 Agenda for Sustainable Development. They provides society with diverse benefits based on regulating, supporting, provisioning, and cultural services.

IUCN’s support for UNESCO Global Geoparks
IUCN has had a long-standing role supporting the UNESCO Global Geoparks Network since its establishment in 2004, and is a non-voting member of the UNESCO Global Geoparks Council, which is responsible for governing UNESCO’s International Geoscience and Geoparks Programme. In 2015, areas designated as part of the network gained a higher status of recognition, following a decision to recognise them fully as “UNESCO Global Geoparks”.
Today the world counts 127 Global Geoparks in 35 countries. They include areas with geological featuresheritage of international significance, which have no formal legal protection and are rather conserved through a bottom-up, community-led approach.
IUCN WCPA Geoheritage Specialist Group
In 2013, a Geoheritage Specialist Group was created under IUCN’s World Commission on Protected Areas (IUCN-WCPA). The group provides specialist advice on all aspects of geodiversity in relation to protected areas and their management.
Since 2015, IUCN’s “Protected Area Governance and Management” handbook contains a chapter on geoconservation. The specialist group is now preparing a 'Best Practice Guideline on Geoheritage Conservation in Protected Areas' and is updating the 2009 “IUCN thematic study on World Heritage Volcanoes.
