Fire impacts on Earth across space and time: a discussion-driven conference

Fire impacts on Earth across space and time: a discussion-driven conference

Earth is the only known planet with fire activity – everywhere else, there is not enough oxygen for this process to occur. Since fire appeared on Earth many millions of years ago, it has played a key role in the development of plant adaptation and the distribution of ecosystems. However, the natural occurrence of fire changed with the onset of human evolution. The purposeful use of fire for ...[Read More]

Who’s afraid of Natech?

Who’s afraid of Natech?

Natural hazards that impact industrial sites and result in technological accidents, causing the release of hazardous substances, are referred to as Natech events. In the popular imagination, Natech accidents are triggered by major natural hazard events. However, experience tells us that low magnitude natural events, such as lightning or heavy rains, are sufficient to cause enormous adverse effects ...[Read More]

Natural Hazards 101: Forecasting and modelling

Natural Hazards 101: Forecasting and modelling

With the Natural Hazards 101 series, we mean to bring our readers closer to the terminology often used in the field of natural hazards, but that may not be so familiar. In the first episode of the series, we focused on the definition of hazard and natural hazard. We moved then to the concept of risk, which brought us to define exposure and vulnerability. Later on, we digested the disaster terminol ...[Read More]

Mitigating Soil Erosion After Wildfires

Mitigating Soil Erosion After Wildfires

Wildfires are a natural element in many ecosystems and play a central role in their dynamics. For example, they clear forest floors and liberate nutrients that can replenish the soil. However, changes in fire regimes induced by anthropogenic factors (such as climate change and land uses) have resulted in fire patterns that harm ecosystems [1]. Let’s see together the issues and the mitigation solut ...[Read More]
