VISCA e-workshop: Discover how VISCA DSS supports viticulturists in climate change adaptation
(Registration is open)

Date: 29th October 2020
Time: 10:00 am -12:00 pm CET (2 hours)


Our consortium is pleased to invite you to 'VISCA e-workshop' to be held online on Thursday, 29th October 2020 from 10:00am-12:00 pm CET. The e-workshop aims to bring wine growers, agronomists, scientific community, commercial partners and others to discover the latest release of VISCA Decision Support System (DSS), its added value and how it supports viticulturists in adapting to climate change. Also, the commercial opportunities and the exploitation of the tool will be discussed.
VISCA e-workshop is expected to be interactive with feedback collection and Q&A sessions during presentations. Registration to the e-workshop is open until 15 October 2020 [click here]. After registration, the link to connect to the meeting will be sent. 

Agenda:

  • Short introduction on VISCA project, key finding and results from the demonstration site 
  • Presentation of the VISCA DSS (phenology, irrigation and weather forecasts information widgets) 
  • Presentation of results achieved
  • VISCA commercial strategy and opportunities
  • Conclusions

How Does VISCA DSS Offer Smart Irrigation Management to Vineyards?

VISCA DSS is integrating climate and agricultural models with farmers’ management specifications in order to design short practices, medium- and long-term adaptation strategies to climate change.

The irrigation widget included in VISCA DSS provides recommendations for weekly irrigation needs based on plant and end-user requirements. This component of the tool has supported the irrigation management across the demonstration sites in Italy, Portugal and Spain. The irrigation model takes into account the plant physiological characteristics, the end-users’ necessities, and the irrigation and weather data during the growing season, to provide accurate irrigation volume forecasts for the next week. The model uses the midterm (weekly) weather predictions which is also included in VISCA DSS.

The irrigation widget in VISCA DSS allows the end-users to have an easy access to the irrigation data. The irrigation widget is divided into three panels (Figure 1). The left hand panel has an interactive map which shows the irrigation block selected in the parcel. The central panel presents the accumulated irrigation predicted (green line) and applied by the end user (purple line) and the right hand panel presents the weekly irrigation applied (purple bar) and forecasted by the VISCA irrigation model (green line).

What would happened if this forecast is not available (Business as Usual scenario)?

Supporting Decisions on Canopy Management in the Italian Demo Site with VISCA DSS

VISCA DSS is integrating climate and agricultural models with farmers’ management specifications in order to design short practices, medium- and long-term adaptation strategies to climate change.

In the Irpinia Valley, located in south of Italy (about 60 km from Naples), a very warm winter influenced the precocity of the budbreak that occurred one week earlier than average. Also, blooming advanced earlier followed by a rainy month of June with some problems of downy mildew. However, with the predictions supplied by VISCA DSS, the Mastroberardino viticulture team was able to contain the disease by increasing the number of treatments sprays, anticipating the action as the prediction of several days of rainfall was given.

Blooming observed in the field - Italian Demo Site (July 2020)

This summer, VISCA DSS, in particular the short-term and mid-term climate forecasts, has predicted lower precipitation than normal and higher temperature than normal in Mirabella Eclano estate in the Campania region, where our Italian demonstration site is located. Before the phenological phase of blooming, the DSS, through the seasonal forecast, predicted a dry and hotter summer than normal, followed by the months of September and October with the same trend. Aglianico is the grapevine under the VISCA experimental plot and it is extremely sensible to powdery mildew disease. The dry season usually influences the development of the fungus directly on the grapes. Therefore, such useful predictions allowed the Mastroberardino vinegrowers to take decisions about the canopy and vineyards management in advance. First of all they programmed:
