We have participated in the Global Gridded Crop Model Intercomparison since its first phase in 2012, drawing together knowledge from across the crop modelling community to try and answer questions relating to how crop yields and water usage will develop under future climates. One important result has been the development of a new data-based method to project future crop yields, which complements traditional modelling approached (Pugh et al., 2016).
Our current focus in this area is on the impacts of ozone on crop yields, developing and applying a new version of the LPJ-GUESS crop model.
Previous efforts have focused on disentangling the response of different crop models to rising atmospheric carbon dioxide concentrations. A report on our pioneering 2017 workshop in Illinois bringing together the global crop modelling and crop FACE (Free Air CO2 Enrichment) communities can be found here.
