Scientists have been puzzled by the origin of the Namibian “fairy circles” for nearly half a century, but now a new study by a team of researchers from the University of Göttingen has revealed the reason behind the mysterious circles. Until recently, scientists had two main theories for the appearance of these mysterious circles. The first theory claimed that the circles were caused by termites, while another suggested that grasses self-organized to maximize water availability. Then, some research suggested that termites and self-organization could be the origin of “fairy circles”. However, the mystery became even more confusing after similar circles were discovered in Australia in 2016, where the link to termites has not been traced. University researchers, who, among other things, have studied potential root damage caused by termites, have pointed to the self-organization of plants as the cause, finding no link to termites. According to scientists, plant water stress is the reason behind the mysterious circles. The researchers’ soil moisture measurements show that the grasses around the circles have significantly depleted the water inside the circles, likely causing the grasses inside the circles to die. “By forming strongly patterned landscapes of evenly spaced fairy circles, grasses act as ecosystem engineers and directly benefit from the water resource provided by vegetation gaps. related formations in various other harsh arid areas of the world, in all these cases plants have no other chance of surviving than by growing in exactly such geometric formations,” explained Dr Stephan Getzin, from the Department of Modeling of Ecosystems at the University of Göttingen There are millions of “fairy circles” about 80-140 kilometers from the Namib coast.

The grasslands of the Namib Desert are covered in millions of strange circles 2 to 10 meters wide, each devoid of grass or other vegetation. Together they form a strange polka dot pattern across the landscape.

Researchers at the University of Göttingen, who, among other things, have studied potential root damage caused by termites, pointed to the self-organization of plants as the cause, finding no link with termites.

According to scientists, water stress in plants is the cause of the mysterious circles.

The researchers’ soil moisture measurements show that the grasses around the circles have significantly depleted the water inside the circles, likely causing the grasses inside the circles to die.
