Abstract: Urbanization is one of the most dynamic processes in the context of global change. Deforestation and an increase in land consumption are considered major drivers of shrinking green spaces in urban and peri-urban areas. Forest loss and gain for the period 2001 to 2014 were analysed for nine European cities and their surrounding areas on the basis of forest-cover change data. Urban footprints as a crucial part of research were derived using object-oriented classification techniques. Based on the classified patterns of urban green space, the extent of spatial growth is analysed and compared in order to derive long-term trends and characteristics for the cities under consideration. The Landsat satellite imagery analysis for built-up areas, in four time steps (for the years 1975, 1990, 2000 and 2010), in combination with tree-cover change data from 2001 to 2014, enables a spatiotemporal analysis. This comparative study aims to identify similarities and differences in the spatial distribution of urban and peri-urban forest areas and spatial urban growth patterns of cities located in Eastern and Western parts of Europe. The results show very similar patterns of shrinking urban green space in cities in both regions of Europe. But the analysis also shows that spatial pattern and magnitude of urban growth and open land consumption during the last two decades present significant differences between former eastern-bloc and western European cities.

GI_Forum publishes high quality original research across the transdisciplinary field of Geographic Information Science (GIScience). The journal provides a platform for dialogue among GI-Scientists and educators, technologists and critical thinkers in an ongoing effort to advance the field and ultimately contribute to the creation of an informed GISociety. Submissions concentrate on innovation in education, science, methodology and technologies in the spatial domain and their role towards a more just, ethical and sustainable science and society. GI_Forum implements the policy of open access publication after a double-blind peer review process through a highly international team of seasoned scientists for quality assurance. Special emphasis is put on actively supporting young scientists through formative reviews of their submissions. Only English language contributions are published.
