Frost Defend

Prediction and protection system of fruit crops from frost damage

An innovative artificial intelligence solution for crop frost prevention

Frost Defend

The project aims to design, develop and demonstrate the benefits of a novel monitoring and frost forecasting tool to mitigate frost injury in high yield agriculture crops.

Crops and frost events

A frost event is a meteorological event that causes water in plants to turn from liquid to solid.

Crops are extremely sensitive to weather and one “freezing event” can wipe out an entire crop. Frost is one of the main factors of agriculture production losses in Europe with losses reaching up to 3.3b Euros per year.

Global warming is expected to have a significantly increased impact on frost damage in Europe. Up to this point, the length of the potentially favourable growing period (i.e. defined as total number of frost-free days per year) of several agricultural crops in Europe has globally increased between 1985 and 2014. Plants that are flowering and leafing out earlier have an increased probability of suffering frost damages.

Frost Defend innovation

Frost Defend is based on cross-disciplinary research that covers agronomical, biological, meteorological and atmospheric sciences. The produced system will take into account:

  • the mechanism of plant frost damage and the strategies that plants employ to adapt to frost
  • the biology and genetics of epiphytic ice nucleation active bacteria which facilitate the development of frost on and in plants
  • the atmospheric processes and properties of atmospheric aerosols leading to ice nucleation, freezing and precipitation events
  • the importance of long range transport and mixing of aerosol sources over the Mediterranean basin.

How Frost Defend works

A smart Internet of Things (IoT) based system that utilizes cost effective sensors will be developed.

Monitoring in real time selected relevant atmospheric (aerosol concentration), meteorological and phenological indicators, the system will be able to assess and predict the vulnerability and sensitivity of different types of fruit trees to frost events through the evaluation of complex processes such as the formation of epiphytic bacteria.

Use Case

During project’s lifetime the Frost Defend tool will be first implemented in selected crops in Aeghion in order for the tool to be tested and evaluated. Then, the tool will be applied in other regions of Greece (Argolida and Laconia) as well as in France (central France and Rhône Valley).

The tool will be tested and evaluated on different varieties of fruit crops, enhancing tool’s uptake after the completion of the project. In particular, apricot trees will be tested as they often suffer from frost events in these regions.
