| Popis: | Aims: Using Life Cycle Assessment (LCA), this study aims to compare the environmental impacts of two different viticultural technical management routes (TMRs); integrated and organic) and to identify the operations that contribute the most to the impacts.Methods and results: LCA impact scores were expressed in two functional units: 1 ha of cultivated area and 1 kg of collected grape. We studied all operations from field preparation before planting to the end-of-life of the vine. Inputs and outputs were transformed into potential environmental impacts thanks to SALCA™ (V1.02) and USETox™ (V1.03) methods. Plant protection treatments were a major cause of impact for both TMRs for fuel-related impact categories. For both TMRs, the main contributors to natural resource depletion and freshwater ecotoxicity were trellis system installation and background heavy metal emissions, respectively.Conclusion: This study shows that the studied organic TMR has higher impact scores than the integrated TMR for all the chosen impact categories except eutrophication. However, the chosen TMRs are only typical of integrated and organic viticulture in Loire Valley and some emission models (heavy metal, fuel-related emissions, and nitrogen emissions) have to be improved in order to better assess the environmental impacts of viticulture. Soil quality should also be integrated to LCA results in viticulture because this lack may be a disadvantage for organic viticulture.Significance and impact of study: This study is among the first to compare LCA results of an integrated and an organic TMR. |
