Article
Since the mid-20th century, countries in Europe have been organized to record information on forest fires and their effects. These initiatives were established at regional and often national level, without major interaction among countries in Europe. With the expansion of the European Union in the 1980s, when Mediterranean countries were incorporat...
Article
Fires are a major hazard to forests in the Mediterranean region, where, on average, half a million hectares of forested areas are burned every year. The assessment of fire risk is therefore at the heart of fire prevention policies in the region. The estimation of forest fire risk often involves the integration of meteorological and other fuel‐relat...

Wildfires, as a global phenomenon, are an integral part of the Earth system which affects different regions of the planet quite unevenly. They are of great concern in Europe: in the European Union alone, over 4000 km2 of our land were burnt in 2019; 3400 km2 in 2020; 5000 km2 in 2021. Depending on the proximity to where people live, and the extent...

Chapter
Full-text available
Summary (excerpts from the chapter) Wildfire risk assessment is fundamental for developing prevention, mitigation and preparedness plans. Many countries have customized approaches to assess wildfire risk and these vary widely among them [...]. The level of elaboration of these assessments is often related to the impact of fires in these regions an...
Article
Full-text available
Forest fires are an integral part of the natural Earth system dynamics, however they are becoming more devastating and less predictable as anthropogenic climate change exacerbates their impacts. In order to advance fire science, fire danger reanalysis products can be used as proxy for fire weather observations with the advantage of being homogeneou...

Global fire monitoring systems are crucial to study fire behaviour, fire regimes and their impact at the global scale. Although global fire products based on the use of Earth Observation satellites exist, most remote sensing products only partially cover the requirements for these analyses. These data do not provide information like fire size, fire...

The environmental and socioeconomic impacts of fire in southwestern Amazon have been critical in the last years. Nowadays, there are several remote sensing products and non-operational methods capable of performing detection and monitoring. In this way, we aim to measure the differences in the total burned area, and burned area under forest between...

Wildfire is one of the most prominent disturbances in forest and grassland ecosystems and considered as a natural risk. Although wildfires maintain ecosystem health and diversity by regulating plant succession and fuel accumulation, controlling age, structure and species composition, affecting insect and disease populations, influencing nutrient cy...

Contemporaneous plant communities may retain a mark of past disturbances in their ecological patterns. However, unraveling the history of disturbance on natural systems at a large scale is often unfeasible, due to the complexity of the factors involved and lack of historical data. Here we aim at demonstrating how comparing observed spatial structur...

In the period 1980s–2010s, 95% of wildfires in Mediterranean Europe were due to human causes. In this highly populated region, socio-economic changes occurred in the last decades have influenced wildfire activity. Socio-economic drivers are difficult to model at regional/global scales due to lack of spatial and temporal homogeneous data sources. In...
