Focus - Irré-LIS®, an example of an irrigation decision-support tool

Abstract

Designed by the ARVALIS-Institut du Végétal, Irré-LIS® is a simple water balance model that can be used to control irrigation based on weather conditions and plot data provided by the farmer. The online tool was used to manage thirty-five thousand hectares of irrigated crops in 2019. It is currently operational for potatoes, grain and fodder maize, seed maize, soft wheat, durum wheat, spring barley, tobacco and soya.
