Clim4Vitis days – Thematic Workshop and Staff Exchange – 1st-2nd December 2020

The fourth Clim4Vitis days were organized by Potsdam Insitute for Climate Impact Research (PIK) in collaboration with the Hochschule Geisenheim University (HGU) during the days 1st – 2nd December 2020. The event has been held online using Zoom platform because of the government restrictions to European mobility due to the worldwide COVID-19 pandemic. The main Clim4Vitis activities of this event concerned the “Effect of global change on viticulture” thematic workshop, the staff exchange involving researchers from Clim4Vitis partners and HGU, and the expert webinar.

The Clim4Vitis workshop (1st December 2020) was composed by four sessions addressing the issues of the impact of climate change on viticulture with a special focus on the German wine regions. Several speakers, from researchers to winegrowers, highlighted the role of climate change in viticulture and the current challenges to find adaptation measure in the emerging and traditional wine regions of Northern and Southern Germany. Some talks focused on ongoing researches regarding wine quality making and the benefit of organic viticulture. The talks were followed by a fruitful discussion between the speakers and participants. More than 70 participants, among them winegrowers, researchers, the president of HGU, the presidents of the German wine growing associations and other stakeholders attended the one-day workshop.

Presentation of Clim4Vitis workshop organized by PIK

The Clim4Vitis staff exchange (2nd December 2020) represented an opportunity for Clim4Vitis partners and HGU colleagues for sharing researches on climate change modelling and precision viticulture. The first session of the meeting was dedicated to the presentation of the experiments and advanced viticultural research of HGU while an overview of the main research of Clim4Vitis partners on climate and grapevine models for viticulture was given in the second and third sessions of the staff exchange event.

Global Change Impacts on Viticulture

Clim4Vitis online workshop 1st December 2020

The emerging wine regions of Northern Europe are evidence of the impact of climate change on viticulture. In recent years, these wine areas became suitable environments to grapevine growing and, for this reason, an interesting challenge for winegrowers of Northern Europe. The aim of the workshop, organized by PIK and HGU on the 1st December 2020, represented an opportunity to evaluate the role of climate change on the European viticulture and the new perspectives of the winemaking sector in German wine regions.

The workshop opened with the welcome given by Prof. Hermann Lotze‐Campen, head of the Research Department 2 "Climate Resilience" at PIK and with the Clim4Vitis presentation led by the project coordinator, Prof. João Santos from UTAD. Afterwards, the first workshop session was dedicated to the impact of climate change on German winegrowing regions (Christoph Menz, PIK), the challenges of viticulture adaptation (Manfred Stoll, HGU) and crop protection (Annette Reineke, HGU) for future viticulture sustainability. The second session was introduced by the president of the German Viticulture Association Klaus Schneider (Deutschen Weinbauverbandes e.V.) and it addressed the emerging viticulture in some northernmost regions of Germany such as, Brandenburg and Sylt (Thomas Kartschall, PIK; Manfred Lindicke, Werderaner Wachtelberg Werder/H. and Christian Ress, Weingut Balthasar Ress, Eltville‐Hattenheim & Sylt).

The third session presented by the president of the Association of German Prädikat Wine Estates Steffen Christmann (Verband Deutscher Prädikats- und Qualitätsweingüter e.V.) was focused on the experience of renowned wineries for high-quality winemaking of southern Germany (Michel Städter, Weingut Schloss Johannisberg; Dieter Greiner, Staatsweingut Kloster Eberbach and Theresa Breuer, Weingut Georg Breuer, Rüdesheim). The last session, introduced by the CEO of the German Association for Ecological Viticulture Ralph Dejas (EcoVin), was focused on the importance of vineyard biodiversity and ecological viticulture, with examples from ongoing research projects BioQuis (Ilona Leyer, HGU) and KliA-Net (Eckhard Jedicke, HGU). At this regard, Simone Loose (HGU) presented the business report on climate change highlighting the current threats and challenges for the wine industry and future expectations.

The workshop was concluded with the last discussion with the audience and with closing remarks of president of the Hochschule Geisenheim University Prof. H.R. Schultz (HGU).

Clim4Vitis stakeholders workshop

Clim4Vitis Stakeholder meeting 11th December 2020
 “Climate change and viticulture: the role of UNIFI”

The stakeholder meeting “Climate change and viticulture: the role of UNIFI” has been held online on the 11th December 2020 involving several agronomists, oenologists and local winegrowers. The aim of the meeting, organized by UNIFI, was to strengthen the collaboration among researchers and Tuscan winegrowers for facing up the current issue of the climate change impact on viticulture.

After the opening session of Prof. Marco Bindi (UNIFI) about the importance of Clim4Vitis event for raising awareness on the impact of climate change on viticulture issue, the meeting schedule continued with the presentations about Clim4Vitis project (Dr. Marco Moriondo, CNR-IBE) and the role of UNIFI in climate change and viticulture research (Dr. Luisa Leolini, UNIFI). Thus, the floor has been given to the keynote speakers: Dr. Gennaro Giliberti responsible for the agriculture sector of the Tuscany region, Dr. Rosanna Matteoli for the Montalbano cooperative of olive oil, and wine (Pistoia province), and Dr. Michele Brandi, agronomist of the renowned Frescobaldi wine company. Finally, the world cafè was organized and the participants were assigned to four different topics on climate change, research, and viticulture (1. The current issues of viticulture, 2. Measures for copping the impact of climate change, 3. The contribution of the research in viticulture, 4. Your farm in twenty years). The discussions addressed by each group were reported and analyzed in the final debate with interesting hints to improve the collaboration among researchers and stakeholders on climate change impacts in viticulture.

Clim4Vitis in the journals and in the news

The consortium has disseminated the project not only in scientific events but also in some major newspapers and radio channels, with the potential to reach a much larger audience in the partner countries.
