Scientists have not yet agreed on the origin of deserts on our planet. I believe that some of the deserts on Earth are of artificial origin. I suggest you pay attention to the border of the Voronezh and Rostov regions.
Incredible sand dunes and sparse vegetation - this is how the desert in the south of the Voronezh region looks like. Its second name is "Don Sahara" or "Dead Field", as you like. For the black earth, this is a unique place that has become a natural monument and was named "Dune hills". At the beginning of the 19th century, sandstorms raged on this territory, as in all deserts.
In Soviet times, Stalin ordered pine trees and other vegetation to be planted along the edges of the desert. At present, sandstorms are no longer to be found. In the middle of the last century, making furrows on the ramparts, workers planted millions of seedlings of pine, willow and other forest species. Thus, the spread of the sands was stopped.
At present, scientists cannot understand - where did the desert come from in the black earth region? They see this as the result of the ice age, but then the glacier delighted the desert on an area of 2 square kilometers? The desert area is located completely unnatural. It is located among fields and meadows, next to forests and lakes. It feels like someone has deliberately poured sand in the area. If we draw an analogy with the origin of the Sahara, then it turns out thousands of years ago there was a small lake that dried up. However, there is not a single hint of the remains of any lake inhabitants.
There is a version that the sand was brought to this place by the wind from Kalmykia. Very strange, because the distance is decent. After conducting laboratory research, this version shattered to pieces. Quartz sands turned out to be structurally identical in composition to the local soil, therefore, they are of local origin.

How could a small desert area appear among forests and lakes? What if this desert is of artificial origin? For example, the desert appeared due to the enrichment of the rock. The version sounds fantastic and angry comments are already being written, but let me explain your position.
Let's briefly recall - in what processes of rock enrichment sand is formed? At all mining and processing plants, the development of deposits is carried out in an open way. A huge amount of overburden, oxidized and substandard ores, as well as waste rock are extracted from the depths, which are stored in dumps. The number of these rocks is estimated at billions of cubic meters. Sand, as a waste of the mining and processing industry, is a material with a particle size of 0.1 to 5 millimeters. It is this size of grains of sand that is found in the desert we are considering.
Sand is part of the components of the extraction and processing of iron and manganese ores. And in the composition of the raw materials for the extraction and processing of ore raw materials in the chemical industry. We can assume that the process of ore dressing took place in this area. Of course, many will write - "what nonsense", but in the Voronezh region there are traces of a highly developed civilization.
The photo shows the Semiluki megaliths. Thousands of years later, we can observe that multi-ton blocks are perfectly polished. What kind of building it was can no longer make out, since it was completely destroyed.
In the Voronezh region, there is a sufficient amount of evidence of the existence of a highly developed civilization in antiquity. Burials were found not far from these places on the right bank of the Don.
Their age is estimated at 45 thousand years. Interestingly, the remains are of a modern type. But according to official science, during this period Neanderthals lived in this territory, but then where did these bones come from? Most likely the age of the bones is equal to the age of the megaliths.
