Wildfires that ravaged millions of hectares of land and forests in Russia last year may have been caused by so-called “prescribed burning” – a controversial practice intended to prevent the spread of forest fire.
That’s according to a new analysis of 2018’s Siberian wildfires carried out by GIS specialists at Greenpeace’s Global Mapping Hub, who found that the overwhelming majority of those fires started close to places where people travel, work or live, or to sites of deliberate ‘prescribed burnings’.
Across the four regions studied the proportion of fires fitting into this category ranged from 65% in Krasnoyarsk Krai to 99% in Amur Oblast. In that province alone, around a quarter of the fires identified – with a burned area of 2.8 million hectares – were spatially linked to areas where the forestry service had conducted prescribed burnings. The mapping hub said this indicated that the prescribed burnings “either caused fires, or did not fulfil their intended function, which is to prevent the burning of dry forests”.
In each of the four regions analysed, a number of wildfires were spatially linked with logging sites, with the total burned area of these fires ranging from 139,000 hectares in Zabaykalsky Krai to 200,000 hectares in Amur Oblast.
