Spatial complexity and temporal dynamics in viticulture: A review of climate-driven scales

Spatial complexity and temporal dynamics in viticulture: A review of climate-driven scales

Viticulture is a complex and dynamic system, where climate is a key environmental component of plant suitability and productivity. From field to farm level, climate also plays a prominent role in ongoing practices, shaping winegrowers’ decision making and adaptive management. With a changing climate, the wine sector faces many environmental and socio-economic challenges, to which winegrowers are required to adapt. Given the perennial nature of grape growing, there is a need to develop strategies that deal with both short- and longterm climate changes, while likewise accounting for contextual vulnerability. The content of this article aims to provide an overview of climate-driven scales, outlining the spatial complexity and temporal dynamics in viticulture. In addressing these aspects, this literature review offers a framework of scale and cross-scale interactions for policymakers and stakeholders to use when considering responses to attenuate climate change and to reduce its impacts on grape and wine production. The article concludes by discussing the local and context-dependent nature of viticulture in a changing global climate, by emphasizing that the question of scale is fundamental to assessing expected impacts, understanding uncertainty and framing sustainable policies and responses over space and in time.

2019: a year of climatic extremes

2019: a year of climatic extremes

The first half of 2019 was marked in France by extreme atmospheric phenomena that could cause major damage in vineyards. In 2019, as part of the Life ADVICLIM and AVVENIR projects, 20 temperature sensors were installed in the wine region of Entre-Deux-Mers. These sensors record the minimum and maximum temperatures according to a time step and have been installed in the vineyard at a height of 1m50 from the ground. The objective is to study the spatial variability of the temperatures according to the local characteristics (ex: altitude, slope, exposure …). Read the article...
Climate modelling at vineyard sale in a climate change context

Climate modelling at vineyard sale in a climate change context

The integration of local climate variability (bioclimatic indices and phenological modelling) into regionalized climate change simulations provides an assessment of the impacts of climate change at the vineyard scale. The knowledge gained using this methodology is the increasing horizontal resolution that better suits the winegrowers concerns.  Overall conclusion highlights the fact that thermal differences within each site are similar to the thermal differences simulated by the climate model between 1986-2005 and 2031-2050 (increase of 200-500 GDD) and between 1986 and 2081-2100 (increase of 500-1000 GDD). Hence, these results give the local winegrowers/stakeholders information necessary to understand the current functioning as well as historical and future viticulture trends at the scale of their site that may facilitate decisions about future strategies.

Shifts in climate suitability for wine production as a result of climate change

Shifts in climate suitability for wine production as a result of climate change

Following the results of the analysis on climate evolution in the Cotnari pilot site (Romania), where climatic change brought between 1961-2010 climate suitability for the red wine production (https://link.springer.com/article/10.1007%2Fs00704-017-2033-9), ADVICLIM researches reveal similar evolutions at the fine scale, favorable to the quality of wines in all the other pilot sites of the project. This time the assessment of the impact of climate change on suitability for the wine production is based on the analysis of the Huglin index values for the 1951-1990 and 1991-2013…. Get more...
The 2017 vintage in Loire Valley

The 2017 vintage in Loire Valley

In the Loire Valley, the growing season of 2017 has been particularly illustrative of the critical role of climate in growing grapes and making wine. After an initial warm period in the beginning of spring that lead to an early onset of vegetative growth, a severe frost event took place in April, the most devastating since 1991. For some wine producing regions in the Loire Valley, such as the wine appellation of Savennières, 70% of the vineyards were affected and as a result, harvest volumes were low in 2017, which are expected to have important economic consequences in the following years. However, a warm and dry summer period has meant that the onset of veraison (beginning of berry ripening) occurred two to three weeks earlier than normal, very similar to 2003. As this earliness has shifted the ripening period to a warmer period of the year, conditions favored berry ripening and allowed winegrowers to produce high quality...
