Oman is an arid country in the Middle East with water scarcity, and hence land and labor management issues hindering agricultural sustainability and food security. Value addition can minimize food wastes, which is crucial to achieve sustainability by improving the land, water and labor productiveness. This study aimed to evaluate and quantify the improvements in land, water and labor productivities through value addition in date cultivated under arid conditions in Oman. Five date factories and different value-added products of the most popular date varieties, Khalas and Fardh were selected for this study. The comparisons were made between productivity improvements of the value-added products and the raw products. Khalas dates value-added with nuts had the highest productivity ratio of 540%, the same for Fardh was 360% while the lowest were in Khalas value-added with flavors with 111% and in Fardh date paste with 129%. In Khalas, the best improvement by the value addition in average land, water and labor productivities from the base-values of 6.93 ton ha-1, 0.57 kg m-3, and 0.82 kg h-1 of the raw date were 25.05 ton ha-1, 2.06 kg m-3, and 2.95 kg h-1 in date with nuts, respectively; while in the Fardh, these were 18.82 ton h-1, 1.55 kg m-3, and 2.21 kg h-1 respectively of the same value-added product. The variations in productivity improvement of selected value-added products could be due to the availability and cost of the raw dates, cost of the value addition, market options and selling price. Value addition showed high potential for improving productivities under arid conditions and is worth making adoption efforts for achieving agricultural sustainability goals.
