Recognizing the importance of geoscience in solving major challenges that humanity is facing today, UNESCO’s General Conference 2021 proclaimed 6 October as International Geodiversity Day. Despite the multitude of services that geodiversity provides, most people are not aware of how dependent on it we are as a society. This is why we need to promote a better understanding of the Earth’s dynamic processes, so that citizens can make informed policy choices that will foster a more sustainable society. What is geodiversity? Geological diversity refers to the natural portion of the planet that is not alive, both at the surface and in the planet’s interior. By geodiversity, we mean the Earth's minerals, rocks, fossils, soils, sediments, landforms, topography and hydrological features such as rivers and lakes. The term ‘geodiversity’ also spans the processes that create and modify these features. Exceptional examples of geodiversity are preserved in UNESCO Global Geoparks around the world. Theme for 2026 The theme for this year’s International Geodiversity Day (IGD) is ‘Geodiversity On Our Doorstep’. The theme is a chance to explore the geodiversity that lies just beyond our own threshold, and asks people to recognise the geodiversity where they are from, where they live, and in their everyday lives.
