The Global Sand Observatory initiative is UNEP/GRID-Geneva’s response to requests to identify knowledge gaps under the UNEA-4 Mineral Resource Resolution (UNEP/EA.4/Res.19). During 2020 and 2021, we reviewed and assessed current terminologies, data classifications, structures, and availabilities as a contribution to orienting future actions on sand, gravel, and crushed rock extraction, transport, and use. This document is the 2nd case study of a series of 3 case study explorations. This analysis will also support academic publications currently in production at UNEP/GRID-Geneva following the UNEA-5 Minerals and Metals Management Resolution (UNEP/EA.5/Res. 12).
