Over the course of the Earth's history, the development of geodiversity has allowed the establishment of biotic diversity on our planet. Just as biodiversity is the subject of studies and protection actions, abiotic nature also needs to be conserved and used more sustainably. One of the ways to do this is to delimit areas where there are elements o...

Since the end of 2019, two new Brazilian areas are candidates to join UGG/GGN; one of them is Seridó Aspiring UNESCO Geopark, located in the country’s Northeast, state of Rio Grande do Norte. It is named after a native Brazilian word, of tapuia tradition — ceri-toh — which means “little or no foliage; little shade,” something that well defines its...

There are several meanings that the concept of nature has acquired in large areas of knowledge.
