Deliverable 20: Report with the 2nd year monitoring results of the vineyards pilots (action C3)

This deliverable presents the results obtained from monitoring of the pilot experiences during the activities carried out up to December 2022 to monitor the action C3. The pilot experiences were implemented by the end of 2019 and beginning of 2020 in Catalonia and La Rioja. The setting of monitoring variables was performed from middle 2020, the first complete monitoring campaign was carried out in 2021, and the second in 2022. Following the monitoring protocol explained in Deliverable 10 (Aranda et al. 2020), this document presents the second-year results obtained in the pilot experiences in vineyards in La Rioja and Catalonia.

The first section is a short introduction to the deliverable, with a briefly description of the pilot experiments and the main objectives of this deliverable. The second section summarises the monitoring protocol, to have a quick overview of the monitored variables in Catalonia and La Rioja. The third and fourth sections detail the preliminary results of the variables measured in both sites of Catalonia and La Rioja during the three campaigns. Finally, the fifth section summarizes the main outcomes found up to this moment.

We have tried to define accurately all the activities that have been carried out this first and second year and that will be carried out in the following years before evaluating the adaptation measures implemented. We have presented the preliminary results of all the environmental variables that are been measuring and also all the variables that are going to be measured, with different methodologies, timings, and protocols: (i) soil properties (soil analysis and soil moisture, soil microbial biodiversity), (ii) vineyard production (total production, grape quality, wine quality), (iii) hydrological and sedimentological response (infiltration rates, sediments, times to response), and (iv) site meteorological conditions (air moisture and temperature, rainfall).
