abstract = {Deficit irrigation (DI) is an agronomic practice in which the volume of irrigation water applied is below
maximum yield requirements, usually during drought-sensitive growth stages. DI is often used when water is
scarce, and farmers need to either reduce the irrigated area or reduce the water supply to the existing irrigated
area. This research presents an agroeconomic model of field efficiencies and related losses to study the relationship
between DI adoption and return flows (RF). Results show that RF are significantly overestimated when
DI is widely adopted as there are no losses when relative irrigation supply (ν) is low. The hydrological impact at
basin level has been illustrated for the Guadalquivir River Basin, showing that RF and water resources are
substantially overestimated when constant efficiency values (an assumption common to many hydrological
models) are used without including the impact of DI on RF.},
