“…Each simulation unit has characteristic soil properties, agricultural management and daily meteorological data. The 0.25 • grid has been identified to attain an adequate distribution of the spatial variability in the input data, to attain representativeness of local effects on a European scale and to limit computational burdens (Hoffmann et al, 2016;Constantin et al, 2019). Two distinct periods of temporal aggregation have been considered.…”

“…More recently, process-based models conceived for site-scale representation have been applied at the regional scales to, for example, calculate national GHG inventories (Smith, 2013) or build statistical models (Del Grosso et al, 2009;Haas et al, 2013). The main challenges to carrying out spatial assessments are represented by the availability and resolution of the input data (Lugato et al, 2014(Lugato et al, , 2017, by the biases introduced into the aggregation or disaggregation of these data in homogeneous spatial areas (Constantin et al, 2019;Hansen and Jones, 2000), and by the model validity regarding spatial-scale change (Hoffmann et al, 2016). Furthermore, the simulation of agricultural production with climate projections introduces an additional degree of uncertainty that can be reduced with a sound evaluation of historical data (Rosenzweig et al, 2013), as proposed in this study.…”

“…When models have been calibrated and evaluated, their outputs can be used instead of real observations, thus model spatialization may be desirable to reduce the working time and cost of obtaining measurements in the field (Acevedo-Opazo et al, 2008Baralon et al, 2012). Models can be used to obtain difficult, infeasible or unavailable measurements (Constantin et al, 2019).…”

“…crop rotations, tillage, irrigation, fertilization) and climate change on crop production and environmental quality (e.g. Bergez et al., 2014; Brilli et al., 2017; Constantin et al., 2019; Dilla, Smethurst, Barry, Parsons, & Denboba, 2018; Eckersten et al., 2012; Robertson, Rebetzke, & Norton, 2015). Existing models can be used to quantify the effects of soil degradation by running scenario simulations with contrasting soil physical and hydraulic properties.…”
