Café des Idées - Science in Conversation
In 2020, the Alliance Française “Café Scientifique” becomes “Café des Idées - Science in Conversation” jointly organised with FAST!* and the Embassy of France to offer a convivial meeting platform for the exchange of ideas, information and discussion for all those who are interested in French-related science and its broader implications for society and the natural environment.
The new format will include the possibility to connect on line or to come at the premices of Alliance Française in Wellington (free admission).

About the topic
Adaptation of vineyards to climate change
Most of studies on vine’s climate adaptability under different climate change scenarios show that we can expect major upheavals at global level, with the disappearance of some wine-growing regions by 2100. These studies, based specifically on climate simulation, propose fairly “brutal” methods to adapt to climate change, for instance moving wine-growing regions. Studies on the impact of climate change only cover major global wine regions, however, without taking into account the spatial variability of climate on finer scales. However, a wine’s specific features are also determined by local scale variations (e.g. slope, exposure, type of soil, etc.), and it is at the scale of the plot that winemakers manage their estate and adapt to the climate, notably by agricultural practices (tillage, work on the vine, etc.). The spatial variability of climate at local scale should therefore be taken into account when defining a rational climate change adaptation policy.
Anne Escalle's biography:
Anne is the new Estate Director of Rimapere Vineyards Limited, small single estate in Marlborough, producing high end wines for the Compagnie Viticole Edmond de Rothschild, based in Bordeaux.
Between 2007-19, she was the viticulturist of a fully NZ owned vineyard, covering 600 ha, in high density, all in the Waihopai Valley. Growing conditions are extreme in this estate with numerous frosts in spring & autumn and drought in summer. She has been exposed to different techniques of frost protection, water management and some precision viticulture technologies very useful on that that scale of vineyard.
The precedent decade was situated in the South of France, in Languedoc Roussillon, where Anne was supporting hundreds of growers as a viticulturist consultant. She covered a large variety of vineyard terroirs and then climates challenges.
More than 25 years of experience in the wine industry did not erode her passion for wine and for finding the best way to optimize a terroir and magnify it in the bottle
Hervé Quénol's biography
Hervé Quénol is geographer-climatologist working as senior scientist at the National Centre for Scientific Research (CNRS) in the LETG (Littoral Environment Remote-Sensing Geomatics) laboratory (Rennes, France). Visiting researcher at the "School of Earth and Environment College of Science" of the University of Canterbury. His research group focuses on the interactions between climate and anthropic activities. His research group focuses research on Analyses and modelling of climate at fine scales in the climate change context; Climatology and Viticulture; Urban climatology. He leads the LIFE-ADVICLIM European project (2014-2020) whose theme is "High resolution study of viticultural adaptation and mitigation scenarios". He also established an International Research Project between France and New Zealand called "High-resolution scenarios for adapting agro systems to climate change: application to viticulture (IRP-VinAdapt)" (2019-2024). He has managed approx. 15 research projects and has authored more than 90 peer-reviewed publications.
