fires

Extreme wildfires are becoming more frequent and causing greater environmental and social impact. Current policies that prioritise fire suppression have not only failed to prevent this situation from arising, but  actually made it worse. The report Changing Wildfires - Policy Options for a Fire-literate and Fire-adapted Europe,  released by the European Academies' Science Advisory Council (EASAC), addresses this issue by outlining eight policy options. The report's key recommendations focus on  putting landscape management first —by regulating biomass structure and land use — and empowering local communities.

Several areas in the region of El Bierzo in León and the province of Zamora have seen numerous forest fires in recent hours, forcing more than a thousand people from different municipalities to evacuate. One person has died. The flames have affected the Las Médulas natural area, listed by UNESCO as a World Heritage Site. Another fire in Tarifa (Cádiz) has forced the evacuation of hundreds of people, and also in Tres Cantos (Madrid), where one person died. In addition, there are active outbreaks in several areas of Galicia. The government declares a pre-emergency phase.

The last few weeks have been marked by devastating fires in Spain and other European countries. In Catalonia, just days after a fire killed two people and burned 5,500 hectares in the province of Lleida, another fire broke out in the province of Tarragona, affecting more than 3,200 hectares and now stabilised, which resulted in another person's death. What are the characteristics of these large fires? How can we prevent them? The Science Media Centre Spain organised an informative meeting with two experts to answer these questions and clarify key concepts.

Two people have died in a fire that has burned more than 5,500 hectares in the province of Lleida. Firefighters from the Catalan government declared it under control last night, after 29 hours. Salvador Illa, president of the Catalan regional government, called for ‘maximum caution’ from the public, warning that ‘today's fires are not like those of the past, they are extremely dangerous,’ according to RTVE.es. Why is this fire considered extreme? What should you do when a fire breaks out? How can more fires be prevented? In this article, we have compiled explanations and basic recommendations with the help of expert sources.

According to a modelling study published in Nature Cities, the frequency of some types of fires in cities is expected to increase in the coming decades as a result of climate change. This increase would be seen in vehicle fires and in those that occur outdoors. The conclusions are based on data from more than 2,800 cities in 20 countries and could be useful for future urban planning and emergency response strategies.

The interface between wildland and urban areas - areas that are at risk of devastating fires - has grown by 35.6 per cent between 2000 and 2020, says a study based on satellite data. The increase has accelerated since 2010 due to growing urbanisation, reaching 1.93 million square kilometres worldwide, adds the study published in Science Advances.

More frequent and severe wildfires increase the temperature of the exposed land surface one year after the fire, according to an analysis of forest satellite data collected from 2003 to 2016. In recent decades, large wildfires have doubled or tripled their average size in eastern Spain, Canada, and western United States, as noted in the research published in Nature. The authors call for consideration of these effects on surface temperature when managing forests.

Abandoned farmlands in Europe could find new life through rewilding, a movement aimed at restoring devastated landscapes to their wild state before human intervention. A quarter of the European continent, 117 million hectares, is ready for rewilding, according to a study published today in the journal Current Biology.

A team led by the Carlos III Health Institute has analyzed how short-term concentrations of particles associated with wildfires and Saharan dust incursions influence hospital admissions in Spain due to mental and behavioral disorders. The results were explained in a briefing organized by the Science Media Centre Spain. 

Wildfires increase the level of tropospheric ozone. An international study, published in The Lancet Planetary Health and involving Spanish participation, suggests that one- to three-day exposure to wildfire-related ozone pollution is linked to increased daily all-cause and respiratory mortality rates. The study analysed more than 700 locations - including in Spain - between 2000 and 2016, calculated the daily concentration of wildfire-related ozone pollution and compared it with data on daily deaths in the areas studied.
