On May 25 we carried out the annual cleaning of the Barjas irrigation channel Cáñar (Granada). This is a medieval irrigation channel that, after 30 years of abandonment, was recovered in 2014, by MEMOLab Laboratory, in collaboration with the Irrigation Community of Cáñar/Barjas. Since then, we have collaborated in the annual cleaning of the ditch, to achieve irrigation in the summer period, ensuring water in the driest periods. This activity has been carried out thanks to the work of  70 volunteers from different interests, who, using traditional techniques, cleaned the irrigation ditch of vegetation and soil accumulated throughout the year.
