    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...

  5. 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...

  6. 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...

  7. An open source geospatial cyberinfrastructure for interdisciplinary collaboration and broader engagement

    26 Oct 2017 | Downloads | Contributor(s): Carol Song

    Solving complex global problems demands that researchers from different disciplines work together, and their analytical tools, models and datasets interoperate. This is especially true in the context of sustainability. For instance, multiple goals of the United Nations Sustainable Development...
