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:

Adaptive actions to support vineyard management using VISCA predictions in Douro Valley, Portugal

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 Douro Valley, where our Portuguese demonstration site is located, the combination of abundant rainfall in March and April of 2020 and a very warm winter influenced the precocity of this year’s growth cycle, with budbreak recorded three weeks earlier than average. These conditions caused recurrent and earlier than expected outbreaks of downy mildew. However, with the predictions supplied by VISCA, the Symington viticulture team was able to plan a very effective treatment schedule, which successfully contained the disease.

Flowering also advanced earlier, arriving two weeks ahead of the regional average, and in order to safeguard good fruit set and ensure a healthy crop, the team at Symington continues to rely on timely VISCA predictions to plan ahead and keep disease pressures at bay.

During April, VISCA DSS predicted higher rainfall than normal in Douro. This increase of precipitation would risk the spread of grape diseases causing some loss of crops. To avoid this loss, the Viticulturists of Symington have decided to make 4 treatments sprays instead of 3 with an earlier positioning than usual in the calendar, to block the downy mildew cycle.

Explore the Preliminary Results of VISCA Project!

VISCA project has been developing a Decision Support System (DSS) that integrates climate and agricultural models with farmers’ management specifications in order to design short practices, medium- and long-term adaptation strategies to climate change. After more than three years since the launch of our project, we are publishing the ‘VISCA Booklet on Preliminary Results’. The booklet gives an overview of the project, a description of the DSS and the integrated climate services, the added value of these services with testimonies from the end-users as well as the preliminary results driven from the demonstration sites in Italy, Portugal and Spain. The booklet also presents an overview of the replicability and the way forward (exploitation). You may download VISCA Booklet here.
