• There is a justified social/environmental/economical pressure
in optimizing irrigation
• In the last mile, irrigation water use is decided by farmers
• Irrigation water requirements vary
• Site-to site depending on crop traits, irrigation setup, soil…
• In time depending on weather, crop development,…
• There use to be a large gap between farmer’s practices and
state of the art in scientific / technical knowledge on irrigation
Introduction. Importance of farmer’s skills and practices
in scheduling irrigation
How to train farmers in
scheduling irrigation?
• In real fields
• In virtual fields
• Fast
• Economical
• Wide variety of scenarios
Takes a long time to see the effects
Irrigation Expert Simulator (IES)
Is a web tool that allows farmers / technicians / students:
1. Define very specific study cases on irrigation
irrigation method: flooding/sprinklers/drippers
crop types: annuals/vegetables/fruit trees/…
environment: soils, weather…
allocated water
2. Propose how they would irrigate that case
3. Receive feedback on how their proposal
could be improved
Goals of the Irrigation Expert Simulator (IES)
• Training tool for irrigation scheduling
Promotion of good irrigation practices:
�Frequent update of irrigation schedules
�Adjust to weather
�Adjust to crop development and its size
�Adoption of regulated deficit irrigation
�Assessment and control of irrigation uniformity
Understanding of key irrigation concepts:
�Evapotranspiration
�Crop coefficient
�Limitations from the soil and the irrigation setup
�Expected range of water requirements by different crops
Workflow of IES
Working with a study case
Support by an Expert System
Approach: Instance-based learning
How the user practices with scheduling irrigation
The IES’s Virtual Crop: a simple crop model
backed by examples
Validation. From experimental plots to regional scale
Conclussions
• A web-based tool has been developed for training farmers and
technicians in irrigation scheduling
• In 2014 the tool will be used to support regular courses on
irrigation by the Catalan Department of Agriculture
• The Expert System approached as Instance-Based Learning has
greatly simplified the algorithms for providing recommendations
and evaluating the responses by students
www.ies-life.eu
IES (www.ies-life.eu ) is funded by the EU Life+ program (LIFE11 ENV/ES/621).
The tool will be accessed from the RuralCat portal (www.ruralcat.net )
which is supported by the Department of agriculture, livestock, fisheries, food and
natural environment of the Government of Catalonia (DAAM).
