Abstract
Proper water management is becoming a must since shortage started to cause
serious problems. The United Nations is stressing on the need to gradually
produce more output and/or value per unit of water. The main purpose of this
study is to improve water productivity. An optimization model was developed
solved by linear programming utilizing the General Algebraic Modeling System
to obtain the optimum cropping pattern that maximizes revenue per unit water
taking into account crop evapotranspiration, land, market and water availability
as constraints. A case study was conducted in Lebanon on an area of 6700
Hectares located in South Bekaa. It was f
