PRERIVID aims to develop a vineyard irrigation management tool that allows predicting requirements based on meteorological data, soil humidity and local weather forecasts. The aim is to determine water needs, develop a prediction model and an irrigation management tool, evaluate the impact of agronomic techniques, use new digital tools to assess water stress and transfer results to the sector.
The project focuses on predicting vineyard water needs based on meteorological data and developing calculation and prediction models, as well as understanding the economic impact of irrigation and crop management practices.
- Model for calculating vineyard water needs and estimating 7-day requirements.
- 7-day prediction model of reference evapotranspiration (ETo) and crop coefficient (Kc) for each phenological stage, for different soil types and different wine-growing areas.
- Irrigation management tool that allows you to determine the current water needs of your vineyard and estimate future irrigation requirements.
- Management of agronomic techniques that affect the water status of the vineyard.
- Effect of water stress and cultivation practices on grape quality.
- Prediction of water stress and nutritional quality of vineyards using NIR spectroscopy.
- Economic impact of irrigation practices and crop management (cover crops and kaolin) on vineyard management.
In a context of climate change, where rising temperatures are expected, as well as an erratic distribution of rainfall, both in quantity and timing, it is increasingly necessary to have tools that help winegrowers efficiently plan irrigation, and therefore, the scarce water resources available.
Deficit irrigation strategies, employing more efficient irrigation systems such as localized irrigation, are the current starting point for vineyard irrigation management. They require the inclusion of new factors that take into account the complexity of the current climate situation and the pressure placed on water resources in our country. The report "Impacts and Risks of Climate Change in Spain" identifies the main impacts of climate change on agriculture as increased water stress, phenological changes associated with seasonal shifts, and damage from heat and extreme events, all of which jeopardize production.
In addition, the study has identified a set of 73 risks, categorized by urgency. Among those classified as most urgent are several that highlight the need for the wine industry to address projects like PRERIVID:
- Risk of reduced river flows or changes in their seasonal patterns.
- Risk of reduced availability of water resources for agricultural and industrial uses.
- Risk of increased eutrophication and/or deterioration of water quality.
- Risk of increasing the area of arid and semi-arid zones due to desertification.
- Risks arising from changes in the phenology of plant species (emergence of leaves and fruiting) that can cause the decoupling of the biological cycles of interdependent species, including animal species.
- Risk of increased impact on crop cycles and changes/reductions in production due to changes in the seasonality of horticultural activity.
- Risk of decreased yield of herbaceous species, especially those irrigated, due to irrigation limitations.
- Risk of loss of farms due to production losses and increased input prices.
PRERIVID aims to develop a vineyard irrigation management tool that allows for predicting requirements based on meteorological data, soil moisture, and local weather forecasts. The goal is to determine water requirements, develop a prediction model and irrigation management tool, evaluate the impact of agronomic techniques, use new digital tools to assess water stress, and transfer results to the industry.
The main results will be:
- Model for calculating vineyard water needs and estimating 7-day requirements.
- 7-day prediction model of reference evapotranspiration (ETo) and crop coefficient (Kc) for each phenological stage, for different soil types and different wine-growing areas.
- Irrigation management tool that allows you to determine the current water needs of your vineyard and estimate future irrigation requirements.
