Il monitoraggio meteorologico come strumento per la gestione della variabilità climatica in Franciacorta

Abstract

[English version below]

Nel 2007 è stata avviata una ricerca nell’areale di produzione del Franciacorta DOCG che ha riguardato un ampio numero di vigneti di Chardonnay con riferimento ai quali sono stati acquisite le serie storiche dal 2001 relative a (i) decorso delle epoche fenologiche, (ii) curve di maturazione e (iii) dati prodotti dalla rete meteorologica consortile. Tali dati hanno permesso di produrre un modello empirico agrofenologico relativo allo Chardonnay nell’areale considerato e di calibrare e validare un modello meccanicistico di simulazione della produttività primaria, chiamato SIM_PP.

In 2007 a research was started on an high number of vineyards in the Franciacorta AOC area. From 2001 to 2009, phonological stages records and ripening kinetics data were collected. Starting from phenological data, an empiric agrophenological model was build, in order to estimate principal stages by using daily cumulated temperature. Furthermore, ripening kinetics were compared to mechanicistic model simulations (SIM_PP, Mariani and Maugeri, 2002). Starting from air daily temperatures, SIM_PP simulates the Net Primary Production, allocation dynamics in sink organs and the sugars storage in berries, using a mechanism based on transpiration and mass transport flux.
The comparison between real in-field situation and gathered simulations allowed to evaluate mechanicistic and empirical models performance.

REDWINE project: use of Chlorella vulgaris to prevent biotic and abiotic stress in Palmela’s region, Portugal, vineyards

The new EU Green Deal aims to achieve GHG emissions reduction by at least 55% by 2030 and a climate neutral EU economy by 2050.
REDWine concept will be realized through the establishment of an integrated Living Lab demonstrating the viability of the system at TRL 7. The Living Lab will be able to utilize 2 ton of fermentation off-gas/year (90% of total CO2 produced in the fermenter) and 80 m3 of liquid effluent (100% of the liquid effluent generated during fermenter washing) to produce 1 ton (dry weight) of Chlorella biomass/year. This biomass will be processed under a downstream extraction process to obtain added-value extracts and applied in food, cosmetic and agricultural end-products and to generate a new EcoWine. REDWine will focus on the recovery of off-gas from a 20.000L fermenter of red wine production existing in Adega Cooperativa de Palmela (ACP, located in Palmela, Portugal).

Analyse de la perception du terroir et de sa valorisation par les viticulteurs de l’Anjou

An integrated terroir characterization is currently realized in the French northern vineyard: “Anjou”. The concept of Basic Terroir Unit (B.T.U.) and its associated ground model “Rock, Alteration, Alterite” are used in this characterization. This work is coupled to a viticultural survey, based on parcels.
