Desert landscapes such as those of Saudi Arabia may be rich in sand, but Times or India states that the grains from the Arab countries are anything but those characteristics.
Unique rock of special format
According to Naturalis Biodiversity Center, every grain of sand has ever started as part of firm rocks. Rocks that lie on the surface are constantly exposed to weathering and erosion through water and wind that crumbles over the years.
For example, the grains of sand that are essential to make concrete, angular and coarse. These offer enough guidance to form a strong, coherent mix in combination with cement and water.

The grains in the deserts of Saudi Arabia are usually too round and too slippery because they have been worn by the wind over the course of thousands of years. And that while concrete is one of the most essential building materials in the Arab regions.
For that reason, the United Arab Emirates, in particular Dubai and Abu Dhabi, also import the international sand to guarantee the build quality of the enormous expansion of the skyline.
‘Sand crisis’
According to the Environmental Program of the United Nations (UNEP), the world consumes around 50 billion tonnes of sand every year. The sand import from Saudi Arabia from Australia and other countries such as China and Belgium underlines the importance of material specificity in the infrastructure, certainly in the heart of the desert. The UNEP indicates that the world is therefore confronted with a ‘sand crisis’.
