Fire & Soil Biogeochemistry (BIOFIRE)

The Fire & Soil Biogeochemistry (BIOFIRE) group investigates the impact of fire on the organic fraction of natural matrices such as soils, sediments, and biomass, integrating biogeochemistry, analytical chemistry, microbial analysis, and modelling. Its goal is to understand the mechanisms controlling the transformation and stability of burned organic matter, as well as its effects on the carbon cycle, soil health, and ecosystem resilience to wildfires. BIOFIRE utilises mass spectrometry, stable isotope analysis, high-throughput DNA sequencing, and chemometrics to identify molecular and microbial compositions, soil health biomarkers, assess erosion, and develop predictive models of soil degradation and recovery. Its interdisciplinary approach has fostered collaborations with institutions in Spain, Portugal, Germany, Italy, Switzerland, Brazil, and the USA, and participation in European consortia focused on wildfires, soil sustainability and the challenges of the European Green Deal.
