How much land is consumed in Germany?

Based on data of the Monitor of Settlement and Open Space Development (derived from the official geodata ATKIS Basic DLM), it has been possible to calculate statistics on land consumption in Germany since 2011. A relatively constant trend in consumption can be observed here, with no sign of a decline in land consumption. A figure of 64 ha/day was calculated for 2016, making it unlikely that the German government will achieve its 30 ha/day target by 2020. At 47.9 ha, built-up areas account for the largest proportion (73.4 %) of consumed land. Much smaller in comparison are transport space (13.4 ha; 22.4 %) and urban open space (2.5 ha; 4.9 %).

The calculation of land consumption requires complex GIS processing steps based on the geometric intersection of two land use geometries. The procedure is described in SCHORCHT et al. (2016). 1
