摘要：The growing demand for minerals has pushed mining activities into new areas increasingly afecting biodiversity-rich natural biomes . Mapping the land use of the global mining sector is, therefore, a prerequisite for quantifying, understanding and mitigating adverse impacts caused by mineral extraction . This paper updates our previous work mapping mining sites worldwide . Using visual interpretation of Sentinel-2 images for 2019, we inspected more than 34,000 mining locations across the globe . The result is a global-scale dataset containing 44,929 polygon features covering 101,583 km2 of large-scale as well as artisanal and small-scale mining . The increase in coverage is substantial compared to the frst version of the dataset, which included 21,060 polygons extending over 57,277 km2 . The polygons cover open cuts, tailings dams, waste rock dumps, water ponds, processing plants, and other ground features related to the mining activities . The dataset is available for download from https://doi.org/10.1594/PANGAEA.942325 and visualisation at www.fneprint.global/viewer.
