Human impact, year 1700 (approximately)
Hugo Ahlenius, UNEP/GRID-Arendal
The GLOBIO-2 model is based on settlements and modern infrastructure such as roads, powerlines and pipelines. This map presents the situation as it could have been before the advent of industrialization, with very little impact and fragmentation. The main human impact at this stage would have been the conversion of land, primarily in Europe.
