Abstract: Water shortage is a serious problem in most countries in theMiddle East. Irrigation water consumes about three-fourths of theavailable fresh water resources in Jordam and many othercountries in the region. This article presents a practical approachto manage and optimize the irrigation water use in the region.The ultimate objective is to minimize the outside water and tomanage the irrigation water use under geographic,socio-economic, and demographic constraints. This approach usesthe added value (net revenue) of one cubic meter of waterconcept in evaluating different irrigation water use management.This concept has been demonstrated, based on a case study in theJordan Valley.This case study shows that water scarcity can be incorporated inirrigation water management by proper choice of crops andfarming patters. The objective function is to maximize the netrevenue from the agricultural production process subjected tolimitation on water and other production and marketing factors.Results of analysis showed that a net water saving of about9%occurred if the objective function is to minimize water useunder the same level of profitability. This example shall beuseful for water and agricultural planners. Sometimes virtualwater is widely exported in form of crops that consumes largeamounts of water without full economic consideration to theadded value of water. In some cases, food imports may be afeasible option in water-poor countries instead of water import. Copyright Kluwer Academic Publishers 2000
