Overview
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 it 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.
History
The International Union of Geological Sciences proposed the international day with support from 108 other scientific organizations.
On 23 November 2021, UNESCO’s General Conference adopted 41 C/Resolution 24 and proclaimed 6 October of every year International Geodiversity Day.
UNESCO identifies 6 October 2022 as the first International Geodiversity Day.

Ways to observe
Explore a local landform, soil, rock or water system and explain how its geological history affects ecosystems and human activity today.
Use a geological map to connect bedrock, soils, groundwater or hazards with land use and settlement patterns.
Compare geodiversity and biodiversity so learners can see where the concepts overlap and where they describe different parts of the natural world.
Highlight geoscience careers and community knowledge connected to water, hazards, minerals, conservation and landscape management.

Who established or recognizes International Geodiversity Day?
The reviewed provenance layer identifies UNESCO General Conference as the proclaiming or establishing body. The proposer or originator is recorded separately as International Union of Geological Sciences (IUGS) with 108 other scientific organizations. Current facilitation or coordination is recorded as UNESCO International Geoscience and Geoparks Programme (IGGP).
Is International Geodiversity Day international or country-specific?
The record has international or global institutional scope: UNESCO international day. That does not mean every country treats the date as a public holiday or observes it in the same way.
How is this page verified?
The factual layer is source-backed and keeps its date rule, scope, provenance and editorial guardrails attached to the authority record. This record was checked on 2026-09-05.
