Description:
The impact of human activities on wilderness qualities has been modelled using the GLOBIO-2 model. The model uses infrastructure and settlements as proxies and measure the degree by which habitats have reduced their wilderness qualities, by fragmentation and disturbance. According to the model, huge tracts of desert areas are relatively undisturbed, the majority of highly impacted areas are in the drylands of Central Asia and North America.
