Limited resources and growing needs for water have triggered a nationwide campaign for water conservation in the Sultanate of Oman. A land and soil survey study of Oman shows the availability of more arable land than present water resources could support. Groundwater is the main source for agricultural production. Overpumping at rates higher than the natural recharge has resulted in lowering of the ground water table, while seawater intrusion has led to an increase in soil salinity. A comprehensive water program is underway to: (1) conserve water through efficent irrigation, use of soil additives, modern irrigation systems, agronomic management, and institutionalization; and (2) augmentation of resources via introduction of more desalinization plants, more waste water treatment, use of brackish water; water fog collection, and water harvesting by building recharge dams.
