Global Human Modification

The global Human Modification map (HM) provides a cumulative measure of human modification of terrestrial lands across the globe at a 1-km resolution. It is a continuous 0-1 metric that reflects the proportion of a landscape modified based on modeling the physical extents of 13 anthropogenic stressors and their estimated impacts using spatially-explicit global datasets with a median year of 2016. <br><br>The HM map was developed by scientists at The Nature Conservancy and Conservation Science Partners. For questions or feedback on this map please contact Christina Kennedy (ckennedy@tnc.org) or James Oakleaf. We welcome the opportunity to hear from and to collaborate with researchers on projects that integrate the HM map into their work.<br><br>For a description of the methods and to cite the use of HM map, see:<br>Kennedy CM, Oakleaf JR, Theobald DM, Baruch‐Mordo S, Kiesecker J.
