Thesis Title
Coupled Effects of Irrigation Management and Water Salinity on Date Palm Cultivars in the Hyper-Arid Environment of the United Arab Emirates

Date palms are culturally, aesthetically and economically important in the United Arab Emirates (UAE). They require irrigation from groundwater as rainfall is virtually non-existent. The UAE groundwater reserves are expected to run-out in approximately 55 years. Furthermore, the groundwater is becoming more saline. Mr Almuaini investigated the water requirements of date palms and found that the sustainable daily rate of irrigation should be 1.5 times the rate at which they use water, as this accounts for a 25% factor-of-safety, and a 25% salt-leaching fraction. This finding represents considerable savings over current practice. A cost-benefit assessment of the option of using desalinated water to dilute the brackish groundwater was completed resulting in a benefit-cost ratio of 1.4. However, the environmental impact of the reject brine will need to be considered.
