Greenhouse gases emissions assessment of viticulture technical itineraries: method and results

Résumé

The aim of Adviclim action B2 is to assess the carbon footprints of technical itineraries for the five project pilot sites. The objectives of doing this assessment were to : 1. identify the main processes responsible for greenhouse gases (GHG) emissions and to characterize some interventions frequently producing high GHG emissions for each pilot site ; 2. identify the proportion of indirect emissions against the proportion of direct emissions from the plot, on which the vine-growers can make modifications ; 3. compare GHG emissions of observed practices against the practices modelled in scenarios with SEVE model (action B1) ; 4. ultimately integrate new constraints in the multi-agents model for systematically reducing GHG emissions when the model proposes new scenarios of adaptation of practices to global warming; 5. extrapolate, if possible, the emissions produced by sampled plots to the pilot site scale according to plots representativity. The application of the assessment method described in a previous methodological report (Demarez et al, 2016) on twenty-seven sampled plots over the five Adviclim pilot sites led to the results presented in the report. They give answers to the two first objectives noted above. The third objective of assessing adaptation scenarios has not been tackled in this report, as the scenarios were not mature enough at the end of the project or were not relevant regarding GHG emissions assessment. But the methodology for assessing them would have been exactly the same.
