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 | 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...

The role of international trade in managing food security risks from climate change

20 Mar 2015 | Publications | Contributor(s): Uris Lantz C Baldos, Tom Hertel

International trade plays an important role in facilitating global food security in the face of a changing climate. In considering this issue, it is useful to distinguish between two different time scales: inter-annual and inter-decadal. Inter-annual adjustments in international trade can play an...

Market-mediated environmental impacts of biofuels

31 Jul 2014 | Publications | Contributor(s): Tom Hertel, Wallace E. Tyner

This paper surveys the evidence on market-mediated environmental impacts of biofuels, with special attention to the indirect greenhouse gas emissions stemming from land cover change in the wake of increased demand for biofuel feedstocks. We find clear evidence that market mediated land use...
