Description :
The aim of this study is to compare the water use efficiency before (2001) and after (2002–2008) implementation of a new irrigation management plan in an area operating with traditional methods. To this end, annual water balances were carried out in a pilot basin (95 ha) in Northeast Spain during the period between 2001 and 2008. From these, the evolution of irrigation quality (Net Hydric Needs, Irrigation Efficiency, and Water Deficit) was analyzed in climatically different years and after changes in irrigation management (i. assignment of irrigation allowances, ii. on-demand flood irrigation system, and iii. creation of water consumption accounts). The changes in irrigation management contributed to a better adjustment between water consumption and net hydric needs of crops, translating into improved irrigation efficiency and drainage reduction.
