Evaluating the environmental profiles of winter wheat rotation systems under different management strategies

Climate change poses a remarkable challenge to global food security, for which wheat is one of the main staple agricultural commodities. The cultivation different varieties winter in Galicia (commercial and native) under rotation systems with potato, maize oilseed rape was evaluated from an environmental point view. general approach this study included gathering inventory data crops, quantification their impacts economic benefits, identify best land management system. Life Cycle Assessment (LCA) used as tool. profiles each system were reported terms nine impact categories. Crop rotations analysed both per hectare € gross margin, so that information can be relevant land-management decisions. Preference ranks established based on normalized score units. results suggest arable operations contribute decisively profile rotations. avoided mineral fertilization processes, carbon storage soil when returning straw field, well electricity production clearly influence Scenarios include native organic are always environmentally preferred ones while alternate crop depends reference unit. Concerning margin gross, scenarios including variety report highest profits, being potato crop. Further assessment needs undertaken differences ways conducting LCA, i.e. attributional vs consequential approaches.
