Abstract: Applying sustainable approaches in the landscape of public and private projects in a desert region (arid or semi-arid regions such as Saudi Arabia) is crucial to preserve natural resources such as water. It is possible to design a desert public university campus to save 82% of water consumption while having a modern landscape. This modern landscape is more acceptable to the campus population than a traditional desert landscape. This is a sustainable native soft and solid landscape for usage in public and private spaces in arid and semi-arid regions. It supports the national and international direction towards transforming into green societies while saving natural resources, i.e., water. Decision-makers, landscape engineers, agriculture engineers, architects' engineers, and any interested person or specialist organization can design their own ideas landscapes following the soft and solid materials quantities and ratios herein with approximately 2.26 L/m2 water consumption rate.
