Hundreds of countries in the world, including Greece, one-third of whose territories are at high potential risk, are numbers of desertification, according to UN figures, which established 17 June as a global day of awareness raising phenomenon.
The figures also say that by 2025 more than 1.8 billion people will be faced with the problem of total water shortage, while two-thirds of the planet will live with the exhaustion of stock depletion. They also say that desertification will cause more deaths than any other natural disaster and that more than 135 million people will be forced to leave their homes because of the phenomenon.
If there is a significant difference with the past, it is the speed at which the phenomenon manifests itself. And in this dizzying speed, man has a primary role. “The characteristic of human destabilization is that this destabilization occurs in a very short period of time. In the past this change began and was completed over a period of thousands of years, “Mr. Zerefos explains to ANA-MPA.
“Today we know that there has been a prolonged period of drought in the copper age, which, according to some scholars, lasted thirty years and according to others even three hundred. It is the period that the Dorians descended from the north and occupied Argos and Mycenae to change the flow of history, “says the distinguished scholar.
The eastern Peloponnese, occupied by the Dorians, is now considered a high risk. All the islands of the Aegean, as well as parts of Central Greece and Evia, as well as Thessaly, Macedonia, Thrace, as well as Central and Southeastern Crete, are still in the red.
Returning to the past, other known drought periods were the beginning of about 100 AD, while another was recorded during medieval times. “More recently, in the 1970s, a new period of drought began in Northwest Africa, which unfortunately continues to this day. From that area we had the first eco-friendly refugees as the desert to Savannah expanded due to drought, “Christos Zerefos says in REA-MPA.
“We know that the water table in North Africa is descending, and that in oasters such as Pharan, on the Sinai peninsula, which once poured water on the ground – and I remember as a child – it is now more than 20 and 30 meters deep. The fact that this change occurs during a person’s life means a lot. The climate has always changed. But human intervention has increased these changes and that’s why we see these phenomena, “he adds.
