According to the AFO by 2050 temperatures could be 6°c everywhere in the world and there will be a huge demand on hydraulic resources, either drinking water or used for irrigation. In Tunisia more than 80% of available hydraulics resources are consumed by the agricultural sector. Unfortunately, the drought is more and more severe and several agricultural lands have turned into desert. Below is a photo taken for one of the main dams in Beni Metir Tunisia at August 2021, the level is a lowest recorded.
In order to save the water used in irrigation, some Tunisian farmers have opted for the use of electronic systems capable of measuring soil moisture at different depth levels. This technology allows those farmers to know the percentage of soil moisture according to the length of the roots of their crops and then give only the amount of water needed by the plant without falling into over-irrigation. This technology has proven to save up to 30% of the water used.
