For so many years have passed, it is still nature's great mystery of the so-called fairy circles that is found in the majestic Namib Desert, stretching towards northern South Africa. These dusty patches range in size from about 12 feet to 114 feet tall that are ringed with a tall grass have been a long debate by researchers.

According to CNN, there are claims that the fairy circles are some kind of impact sites of meteorites, while researchers theory said it is an act as water reservoirs. Another major theory is that the fairy circles is created and maintained by sand termites as their nest's area. A hole in the soil is believed that the termites establish permanent reservoirs of rainwater to sustain them and the surroundings.

Too many speculations and papers have been proposed but they still end up debunking. That's why researchers ended up creating computer models and what they witnessed has been provided by a unifying theory. Researchers believed that the fairy circles is a result of competition between colonies for space and resources.

In addition, Phys Org reported that the researchers have been conducted extensive measurements on its infiltration rate, soil moisture, its grass biometric, and the distribution of a sediment grain-size. The flow rates of the water were measured inside and out of the fairy circles, which has a very fast infiltration rates in the inner part of the circle.

The researchers also found that a grass roots on the inner side of the circle is competing for water, that means, when the rain comes, the water will flow on the edges of the circles for their use. The investigation that is associated with the fairy circles has been providing new insights on the ecohydrological processes.

To support the termite theory, the researchers reached out to a termite expert to gather more evidence that termites are among the in and out of the fairy circles. However, the hypothesis is on the weakest stage because it did not account for a large-scale hexagonal fairy circle order.
