'Geodiversity' is a shortened version of the phrase 'geological and geomorphological diversity' and has been defined as 'the natural range (diversity) of geological (rocks, minerals, fossils), geomorphological (land form, processes) and soil features. It includes their assemblages, relationships, properties, interpretations and systems' (Gray, 2004)
In simple terms - Geodiversity is the variety of rocks, minerals, fossils, landforms, sediments and soils, together with the natural processes which form and alter them.
Human well-being is based on the diversity of geological resources. These resources have been used since the early years of human evolution and play an essential role in the economic and social development of humanity.
Our theme for this year's Geoweek 2022 is 'Geodiversity - Earth in its many forms'.
So why Geodiversity and why is Geodiversity important? Humans have been utilizing the geodiversity of the planet skillfully and the modern society would not be able to function without the geological resources. The house we live, various appliances, cooking gas, fuel for vehicles, cosmetics and daily used products are all come from the geological resources. Take the example of the mobile phone, which has become a part and parcel of everyone’s life. A single mobile phone uses over eleven different geological materials, which includes plastics, copper, glass, aluminum, Iron, silicon, nickel, tin, lithium, cobalt and graphite. Similarly, computers/ Laptops and many other modern gadgets rely on as many geological resources. Many sports like hiking, rock climbing, skiing rafting, etc. are dependent on geodiversity. Geotourism and Geoparks are also based on the Geodiversity.
The world 's geodiversity is of value in several respects but is threatened by human activities (Gray, 2004). Geodiversity is linked to Biodiversity, so Nature conservation and Natural Resource Management should take into consideration both Living and Non-living Earth/Nature.
