A review of global-local-global linkages in economic land-use/cover change models

04 May 2019 | Contributor(s): Tom Hertel, Thales A P West, Jan Börner, Nelson Benjamin Villoria

Global change drivers of land-use/cover change (LUCC) like population dynamics, economic development, and climate change are increasingly important to local sustainability studies, and can only be properly analyzed at fine-scales that capture local biophysical and socio-economic conditions. When...
