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...

SEPIDROUD DAM GEODETIC DATA

19 Nov 2018 | Contributor(s): homeira mahmoudi (contributor)

Large and sensitive structures such as dams, power plants and towers are of great importance and the behavior of such structures is usually made in geotechnical and geodetic ways (engineering geodesy). In today's world, there are virtually no large structures in developed countries that...

Using spatially explicit data to improve our understanding of land supply responses: An application to the cropland effects of global sustainable irrigation in the Americas

09 Aug 2018 | Contributor(s): Nelson Benjamin Villoria, Jing Liu

Land supply elasticities determine the rates of land conversion in global policy models. However, they are only available for few countries in the world. Therefore, analysts seeking to improve the spatial resolution of their models are forced to impose regionally homogeneous parameters...

An open source geospatial cyberinfrastructure for interdisciplinary collaboration and broader engagement
