Crop modelling: towards locally relevant and climate-informed adaptation

Louise Beveridge, Stephen Whitfield, Andy Challinor
2018 Climatic Change  
Place-based approaches study local and contemporary dynamics of the agricultural system, whereas climate impact modelling simulates climate-crop interactions across temporal and spatial scales.  ...  We propose a research agenda that uses methodological approaches from both the modelling and place-based approaches to work towards climate-informed locally relevant adaptation.  ...  The term 'Crop modelling' refers here to studies that use process-based crop models to simulate the impact of weather, climate and management decisions on yield.  ...
