Egypt is faced by potential water scarcity due to increasing water demand. Hence, agriculture is under stress due to increasing competition for available water. Water-saving efforts should be made, especially in the old lands where irrigation pressing problems prevails, to increase water use efficiency in agriculture. This study attempts to answer two questions: What would happen if water-saving technologies and practices were scaled?up over the old lands during (2013-2017)? What is the impact of using such technologies and practices on water consumption and efficiency and food security in Egypt? Quantitative methods of analysis were used for published data to address both questions; water consumption, saving, efficiency, and self-sufficiency. The results show that laser levelling ranked first in terms of water saving for most crops, followed by the technology package promoted by the Integrated Irrigation Improvement and Management Project, dry planting, deficit irrigation, and alternate furrow irrigation. Laser levelling, the technology package, deficit irrigation, dry planting, raised bed planting, and alternate furrow irrigation were the best alternatives from water productivity standpoints whereas, laser levelling, the technology package, deficit irrigation, and raised bed planting gained the highest economic efficiency for most crops. Using most of these technologies and practices improved the self-sufficiency.
