“…based on high-resolution LiDAR campaigns such as those from the GEDI mission [ 89 ], can also advance the quantification of geodiversity metrics at fine resolutions over a large spatial extent, for example by allowing better detection of first-order streams in mountains which are underrepresented in the currently available HydroSheds dataset [ 90 ]. Additional information on artificial dams, drainage and irrigation channels [ 77 , 91 , 92 ] or groundwater, springs, wetlands and other ‘water-related’ geofeatures could be relevant to include for capturing hydrological diversity globally and within UGGs [ 78 ].…”

The aim of UNESCO Global Geoparks (UGGs) is to protect globally significant geoheritage and geodiversity, but quantitative evidence on the global representativeness of geodiversity components (i.e. geology, soils, geomorphology and hydrology) in these geoparks is in short supply. Here, we provide a first assessment by deriving a global map of geodiversity to test whether the presence of geodiversity components in UGGs is representative for the global availability and distribution of geodiversity. Using openly accessible global datasets and a newly developed workflow, we have calculated metrics for each geodiversity component and a global geodiversity index; we then quantified whether UGGs represent global geodiversity and then compared their components to a randomized spatial distribution of geoparks. Our results show that lithological and topographical diversity are more represented in UGGs than outside these sites, while soil type and hydrological diversity are not significantly different. Furthermore, individual soil types and lithological classes are under-represented and unevenly distributed in Asian and European UGGs. This is probably caused by the concentration of geoparks in Asian and European mountains. To better conserve geodiversity, we suggest an initiative to consider the protection and representation of all geodiversity components in their global context. This article is part of the Theo Murphy meeting issue ‘Geodiversity for science and society’.
