Climate change impacts on European grapevine yields through a dynamic crop modelling approach

Abstract

Climate has a predominant role on growth and development of grapevines. Therefore, climate change represents an important challenge to the winemaking sector. The present study aims to develop climate change projections for grapevine yields in Europe. For this purpose, gridded climatic variables over a recent-past (1950-2000) and RCP8.5 future scenarios (2041-2060), are coupled with the STICS crop model. For each grid-cell in the European sector, soil (e.g. type, texture, depth) and terrain parameters are determined and used as model inputs. Grapevine and crop management variables are also defined. Yield simulations under current and future climates are then compared to identify climate change signals. For the recent-past, the crop model is able to properly simulate yields for the main current European wine regions, showing lower yields in Southern Europe and higher yields in more central/northern regions. For the future, the results depict an increase in yield in the later regions, and a decrease in the former, mostly over inner Iberia. The projections also show a northwards extension of the potential grapevine growth areas, emerging new potential winemaking regions in northern Europe. The current study is a first attempt to apply the STICS crop model to the whole European sector, by using climatic, soil and terrain data as inputs, and the results are thereby preliminary. By using climate change projections as inputs to crop models, the present approach may represent a key decision support system for the European winemaking sector.

Oenological potential of wines and agronomical characterisation of grapes from five white resistant Italian varieties at Serra Gaúcha, Southern Brazil

Rio grande do sul is the main grape producing state in Brazil, with the largest wine-growing area, responsible by 90% of the national production of wines and grape juices. Serra Gaúcha is the main vitivinicultural region, where around 15% of the area is destined to produce wines from vitis vinifera L. grapes. This region presents high rainfall during the grape maturation cycle, a factor that leads to great risk of attacks by fungal pathogens. the use of resistant varieties can reduce the cost and quantity of spraying, improving wine quality, focusing on a sustainable vitiviniculture.

Monitoring of alcoholic fermentation: development of an applicable in-line system

Alcoholic fermentation plays a crucial role in the winemaking process. In addition to producing ethanol, it results in the formation of various secondary metabolites that significantly influence the wine’s characteristics.

Différenciation mésoclimatique des terroirs alsaciens et relation avec les paramètres du milieu naturel

The influence of climatic conditions on the development of the vine and on the quality of the wines no longer needs to be demonstrated at the scale of the vineyard, by the regional climatic characteristics, determining on this scale the viticultural potentialities (Huglin, 1978; Branas, 1946; Riou et al ., 1994); but also on a local scale, at the level of the basic terroir unit (Morlat, 1989), by the landscape differentiation of the natural environment inducing climatic variability within the same vineyard, and partly explaining differences in functioning of the vine, in connection with the processes of maturation and the quality of the wine (Becker, 1977 and 1984; Morlat, 1989 and Lebon, 1993a). According to these authors, the climatic diversity in a wine region constitutes in addition to the edaphic component, an important component of characterization of the Basic Terroir Units (UTB).
