Trees near a fissure through which a magma eruption will later occur use water and carbon from the depths of the volcano. And they accelerate their growth during this phase. An international research team led by Markus Egli and Paolo Cherubini (WSL) was able to prove this by analysing the annual rings and with the help of infrared satellite images on Mount Etna in Sicily.
Trees can deposit pollutants in their tissues over decades and centuries, becoming witnesses to environmental pollution. In an interview with RSI, Paula Ballikaya and Paolo Cherubini explain what dendrochronology tells us about the environment and human history.

Die Schlacht wurde angeblich entscheidend von der Landschaft geprägt. Doch wie sah es rund um den Ägerisee damals aus? Ein integratives Projekt von Geographie-Studierenden ging im Jahr 2014 dieser Frage nach.
Fertile soils are one of the foundations of life on earth. According to the United Nations, one third has already been lost. Researchers at the Department of Geography have now used a new method to decipher the temporal variations in soil erosion and regeneration over the last 100,000 years in the Sila highlands of southern Italy.
