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]. …[Read More]

Floods in the Anthropocene: the good, the bad and the ugly
The interplay between human societies and floods dates back to Old World civilizations. Floodplains have provided the potential for prosperous agriculture and for the development of organised communities and urban cultures. Contextually, flood events have caused millions of fatalities and invaluable economic losses throughout history. Over the past decades, human activities have increasingly altered the …[Read More]
2020: The escalation of extreme rainfall events in Brazil
In summer 2020, extreme rainfall events dumped up to 320 mm of rain in a single day in the Baixada Santista metropolitan region, São Paulo state, breaking Brazil’s record for the biggest rainfall in a single event and demonstrating one of the greatest threats of climate change. The damage caused by the associated landslides led …[Read More]

In the afternoon of August 29, 2020, an intense supercell, which is a thunderstorm characterized by the presence of a deep, persistently rotating updraft, affected the province of Verona in the north of Italy (Figure 1). It was not the first event of this kind; several other events, including tornado episodes, had already occurred during …[Read More]
How satellites measuring soil moisture provide a new understanding of rainfall patterns
Soil moisture and rainfall are the two fundamental variables in the water and energy cycle and their knowledge in many applications is crucial. For instance, for predicting the occurrence and the magnitude of flood and landslide events the knowledge of the initial soil moisture condition and of rainfall amount is mandatory. In the last decade, …[Read More]
