In early December, within the hills of Dalías, close to Almeria, a gaggle of thirty firefighters from INFOCA, the firefighting service of the area of Andalusia, have been torching an space of brushwood inside a 40-hectare plot. Wanting on have been researchers in addition to firefighters with expertise in managed fires. This was no pyromaniac spree however moderately a well-planned check of “pyric herbivorism”, a part of a programme carried out by analysis centres in three Spanish areas: Andalusia, Galicia and Navarra.
What is occurring in Dalías is an experimental trial of the COMPAS programme. The results of managed fires are being studied right here, an space which has a very dry local weather that’s vulnerable to desertification and wildfires. In local weather phrases, it’s consultant of many different locations within the Mediterranean basin and past.
Using hearth to take away tinder – i.e., dry wild vegetation that has gathered over time – is nothing new. Up to now it was widespread follow to burn vegetation as a way to scale back the potential for bigger, uncontrolled fires.

Hearth has at all times been used as a software to “tame” pure landscapes and to fertilise soil. The traditional Romans “cleaned” forests in a course of they known as lucus, a phrase that has the identical root as “gentle” and “shine”. In Australia, a rustic that noticed 25 million hectares burn in 2020 – the equal of the Italian peninsula – the Aborigines as soon as used hearth as a way of domesticating the panorama. Their methods are described in a ebook by creator Victor Steffensen, who proposes that the strategy be revived.
Till the mid-Twentieth century in southern Europe, the mountainous panorama was a mosaic of conventional farmland combined with forest and villages. Hearth was extensively used to form the panorama and there was widespread data of this follow. With the agricultural exodus of latest a long time, the stability has shifted. The panorama is changing into extra homogeneous and thus weak to massive fires, whereas hearth as a software is regularly disappearing from our creativeness and use.
The intention of tasks resembling COMPAS is to reintroduce using hearth and grazing in a mixed type, a way often called “pyric herbivory”. Justo Porfirio Arroyo, a technician from the hearth service INFOCA and a member of REPCA (Purple de Áreas Pasto-Cortafuegos de Andalucía) and the affiliation Shepherds for the Mediterranean Mountain, is in control of figuring out the areas the place hearth could also be used, and for contacting shepherds there. He explains: “First an space is recognized the place there’s grazing land and the place there’s a excessive threat of fireside. Then the burning of a selected space is organised by a specialised crew, in order to take away brushwood and low vegetation. After a couple of months, grazing is carried out on the plot. This usually means goats and sheep, which favor the brand new shoots that emerge after the hearth. These are extra tender than wild vegetation which have grown and withered over time.”
Ana Belen Robles is a accomplice within the COMPAS undertaking, based mostly on the Zaidín Experimental Station in Granada. “Though it’s stunning, floral biodiversity will increase after burning and grazing”, she says. “And now we’re seeing that insect biodiversity additionally improves. Managed fires don’t attain excessive temperatures, so the soil does not get too sizzling, which occurs in bigger fires, and subsequently the soil fertility cycle is quicker. […] The issue at the moment is discovering shepherds. There are only a few left. You will need to realise that intensive grazing doesn’t solely lead to ‘meat and milk’ for consumption. It’s way more. it supplies ecosystem companies to the panorama.”

Up to now, it was the shepherds themselves who used hearth to clear the mountains. This follow has been deserted, partly because of stricter hearth legal guidelines. Robles explains: “Immediately, the quantity of natural gas is way increased than up to now. After a long time of neglect, the shepherds now not belief themselves to make use of hearth, for concern that it’d get out of hand.”
Because of this, the COMPAS undertaking envisages schooling in order to create a brand new skilled position, that of the ‘gas supervisor’, i.e., folks expert in decreasing the buildup of forest mass, the stuff that makes forests dense and impenetrable. This gas is definitely ignited through the driest and most arid months. Mixed with the consequences of local weather change, the best circumstances are thus created for big, uncontrollable and damaging fires. “After understanding which regional legal guidelines at present restrict the follow, we have to promote using these managed fires mixed with intensive grazing,” provides Robles.
In Spain, round 60 % of forests are privately owned, and it’s not at all times simple to persuade the homeowners of this high-fire-risk land that managed fires can perform as a type of prevention. It’s essential to boost consciousness of the truth that hearth might be an ally in adapting to local weather change, moderately than one thing that have to be suppressed in any type.
Using intensive grazing is a way that has been used for years by authorities resembling INFOCA, however it’s not the one one. The removing of brushwood tinder can be executed with heavy equipment or manually by expert labourers. “However some areas are very troublesome to entry with machines or lighter instruments, whereas animals resembling goats and sheep can get there with out issues”, says Justo Porfirio Arroyo. “A mechanical job prices about €900-1000 per hectare, and might go as much as €2,500 if the vegetation is dense. With grazing, upkeep prices a mean of €60 per hectare.” The pastoralists subsequently obtain an financial subsidy from INFOCA based mostly on varied elements, such because the slope of the land and the kind of vegetation. On this manner, they create “firebreak” areas with much less gathered gas, and in a way they tame the panorama.
Using managed hearth appears to be an more and more needed answer for southern Europe and past, and can be endorsed by the European Surroundings Company as a type of climate-change mitigation. As a synergy between the abilities of firefighters, forest managers, pastoralists and out of doors consultants, this method could possibly be the important thing to stopping the megafires of the longer term.
