The AgMIP Gridded Crop Modeling Initiative (AG-GRID)



Main Contacts for Initiative

Joshua Elliott and Christoph Müller 

Brief Description of Activity 

AgGRIDwas formed around the Global Gridded Crop Model Intercomparison (GGCMI) which  was created in the forming process of ISIMIP. AgGRIDalso hosts regional and topic-specific gridded crop modeling activities and interacts with the ag econ team. 

Overview of Participants

31 registered modeling groups from around the world, mainly Europe and North America.

Current Research Focus

Phase2: large 5-dimensional input sensitivity analysis (CTNW-A) on CO2, Temperature, Nitrogen, Water and Adaptation

Recent Noteworthy Finding

•  Growing season adaptation can compensate substantial shares of warming damage
•  Irrigation is often no fully-effective adaptation measure but only an intensification measure
•  Response patterns of models vary across models and in space

Reports/Papers Submitted/Published soon

Müller: yield variability; Folberth: modeling frameworks; Schewe: heatwave; Wang: field warming vs. models; Wartenberger: AET; Wang: irrigation contribution

Ag-GRID is led by Joshua Elliott and Christoph Müller 



Ag-GRID provides a central organizing hub for a new generation of gridded crop modeling activities within AgMIP. Ag-GRID leverages existing AgMIP strengths by bringing together AgMIP members from the climate-crop modeling, IT, economics, RAPs, scaling, and uncertainty teams to develop new initiatives for improving quality and access to gridded data, models, computing, and scenario development and coalesce the international community of large-scale gridded crop modelers around the most important topics at the interface of food and climate. 

Ag-GRID is coordinated from the University of Chicago and Argonne National Laboratory Computation Institute, the NASA Goddard Institute for Space Studies in New York City (the site of the AgMIP Coordination Office), and the Potsdam Institute for Climate Impact Research in Germany. The Coordination Team is led by Joshua Elliott and Christoph Müller and welcomes questions, comments, requests, ideas, project proposals, or criticisms and can be contacted at 

Among the Ag-GRID initiatives is the Global Gridded Crop Modeling Intercomparison. GGCMI brings together a diverse international community of crop modelers for climate impact assessment, model intercomparison and improvement at the global scale. GGCMI aims to better understand climate impacts on global food production, including regional and temporal variations.
