About International Geodiversity Day
International Geodiversity Day is observed on 6 October. UNESCO’s General Conference proclaimed it through 41 C/Resolution 24 on 23 November 2021.
Geodiversity refers to the variety of rocks, minerals, fossils, soils, landforms and geological processes that shape the Earth. The day highlights how this underlying physical diversity supports ecosystems, resources, landscapes and human societies.
Why International Geodiversity Day matters
Geodiversity is often less visible in public discussion than biodiversity, but geological materials and processes underpin habitats, soils, groundwater, natural resources and many aspects of disaster risk.
UNESCO uses the day to connect geoscience knowledge with sustainable development, education and informed decision-making. The observance is administered through UNESCO’s International Geoscience and Geoparks Programme.
