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...

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...

New science of climate change impacts on agriculture implies higher social cost of carbon
22 Nov 2017 | Publications | Contributor(s): Frances C. Moore, Uris Lantz C Baldos, Tom Hertel, Delavane Diaz
Despite substantial advances in climate change impact research in recent years, the scientific basis for damage functions in economic models used to calculate the social cost of carbon (SCC) is either undocumented, difficult to trace, or based on a small number of dated studies. Here we present...
