the Research Problem Lies In The Limited Agricultural Water Resources And The Low Efficiency Of Their Utilization, Necessitating Efforts To Maximize The Return On Water Units To Enhance Productivity. Northern Delta Governorates Suffer From Irrigation Water Shortages, Primarily Due To Their Location At The Ends Of Major Canals, Alongside High Water Losses. This Study Aims To Shed Light On The Current Status Of Water Allocation Development For Rice Crops And Water Losses Associated With Rice Production In Egypt. It Also Seeks To Evaluate The Net Return Per Water Unit, Irrigation Water Productivity, And The Water Requirements Per Ton Of Rice. The Study Achieves These Objectives By Addressing Several Sub-Goals, Including Analysing The Economic And Productive Indicators Of Irrigation Water Use For Rice Crops And Examining Temporal Trends Of Key Irrigation Water Use Factors For Rice. The Research Primarily Relies On Secondary Data, Both Published And Unpublished, For The Period (2005-2022) Sourced From The Central Agency For Public Mobilization And Statistics And The Central Administration Of Agricultural Economics Under The Ministry Of Agriculture. To Achieve These Objectives, Inductive And Deductive Methods, Descriptive And Quantitative Analysis, And Simple Regression Techniques Were Employed, With A Comparative Evaluation Of Models To Select The Most Statistically And Economically Logical. The Key Recommendations Include Reducing Water Losses By Improving Irrigation Water Transportation, Lining Main Canals, And Adopting Advanced Irrigation Systems To Reduce Both Water Losses And Irrigation Costs. Additionally, Developing Short-Duration, High-Yield Rice Varieties Is Emphasized To Increase The Return Per Water Unit.
