Introduction
Wanting on the map of the depopulation in inland areas of the Mediterranean, one can see that it overlaps to a big extent with the map of forest fires recorded by satellites. That is nothing new for researchers engaged on fires and local weather change: the connection between the 2 phenomena is well-known. But it might not be appropriate to attribute causality with out contemplating different components. To know the connection between fires and rural exodus, we went to the websites of probably the most devastating fires of summer time 2021 in Spain, Italy, Greece and Cyprus.
Half 1. Italy and Greece: pleasant fireplace and enemy fireplace
Sa Tanca Manna, the thousand-year-old olive tree image of Cuglieri, was a supply of actual satisfaction for native individuals. Sixteen metres tall and ten metres extensive, the tree was thought of the progenitor of all of the olive bushes on this nook of northwestern Sardinia recognized for the standard of its oil. It was an instance of botanical archaeology. The tree died final summer time, sufferer of a brutal fireplace that swept by way of the Montiferru countryside, burning greater than 20,000 hectares of land and bringing the complete native financial system to its knees.
“The flames destroyed greater than half of our olive bushes, and final autumn’s harvest was so poor that we produced lower than half of the earlier yr’s crop,” says Laura Cocco, 26, supervisor of the Peddio oil firm, which was among the many many companies that suffered heavy losses. “Many have been replanted, however it is going to take years, maybe a long time, earlier than the bushes are as productive as they as soon as had been.”
The Montiferru fireplace was one among many who ravaged Italy final summer time in what was the most well liked yr ever for the nation. 4 instances the forest space was destroyed in comparison with the earlier decade’s common. Issues had been no higher in the remainder of Europe. In keeping with Effis, the European Forest Fireplace Data System, greater than half 1,000,000 hectares of land went up in smoke within the European Union in 2021, the second worst determine ever recorded on the continent. The Mediterranean area suffered probably the most.
But, if one seems on the total image, the variety of fires on the northern facet of the Mediterranean has decreased in current a long time. What has elevated are what are referred to as mega-fires, i.e. these overlaying an space of greater than a thousand hectares. The looks of this new era of fires is carefully linked to ongoing local weather change, which within the Mediterranean area is creating climate circumstances beneficial to fires. However the altering local weather additionally interacts with one other pattern going down all through the Mediterranean area: increasing forests.

As lately as a century in the past, when many European nations nonetheless relied on native timber to assemble buildings and boats and infrastructure, forests lined solely about 3 % of the continent’s land. At present the determine has nearly quadrupled attributable to reforestation schemes, extra environment friendly constructing supplies, and urbanisation. Within the Mediterranean space, the place forests have expanded by about 28 % because the Nineteen Nineties, woodlands occupy 21 % of the land space.
The rise has been notably placing in Italy, the place forests have grown by 75 % within the final 80 years to cowl nearly half of the nation. Many of those forests have reappeared in rural areas which have been progressively deserted by people and their farming and grazing actions. The municipality of Cuglieri, for instance, has gone from 2980 to 2500 inhabitants within the final ten years, a inhabitants decline of 20 %. In Italy there are 3805 municipalities – greater than half of the overall – the place the common variety of inhabitants has fallen by 22 %. 44 % of those are situated within the south and on the islands, the identical areas the place fires have elevated in depth and frequency.
Because of this, based on many consultants, it’s someday…
