In water-lim ited environments, water conservation is a means to increase agricultura! production. lt is also related to !he protection of soil against erosion and !he preservation of water quality. Water conservation can be approached at difieren! scales. In closed basins (basins with no discharge of usable water even in !he wet season}, water is conserved only by reducing consumptive use. There is a wide range of hydrological solutions to conserve water at basin scale. Water productivity (!he production to water use or consumption ratio) is increased by reducing non-beneficia! use and by regulating irrigation applications as to reduce transpiration in smaller proportion !han yield. lrrigation efficiency (!he beneficiallyused irrigation water to irrigation supply ratio) can be enhanced through various engineering solutions such as subsurface drip irrigation, site-specific variable rate irrigation, etc. These solutions reduce !he use of irrigation water and energy although they do no! necessarily reduce consumptive use. Therefore, engineering solutions for water conservation a! farm level do no! imply basin-scale water conservation always. However, physiological solutions such as regulated deficit irrigation or drought toleran! crops are directly linked to basin water conservation because they goal is to reduce transpiration and !he ratio yield : transpiration. In sorne situations, this goal is plausible; however, in others it conflicts with food production and food security, thus it should no! be generalized .
