Broadly defined, land systems ‘represent the terrestrial component of the Earth system and encompass all processes and activities related to the human use of land, including socioeconomic, technological and organizational investments and arrangements, as well as the benefits gained from land and the unintended social and ecological outcomes of societal activities’ (Verburg et al. 2013). In short, land systems capture the ecological and socio-economic characteristics of land but these are not available in single datasets. In order to characterize land systems with their socio-ecologic characteristics and multifunctionality, data that is collected for different purposes needs to be integrated (Ornetsmüller et al. in review at Landscape and Urban Planning).
