Fire is an essential contributor to the equilibrium of many terrestrial ecosystems, and plays a key role in shaping global biomes. However the frequency and severity of wildfires is changing in response to multiple factors, including suppression policies and fuel accumulation, climate change, incorrect forest management and rural abandonment. What are the impacts of these fire regime changes on ecosystems, soils, water resources and communities? This session aims to understand and predict the impacts of fire from a multidisciplinary point of view, integrating the impacts on the physical and chemical properties of soil and ash, hydrologic, erosion and water quality impacts, and vegetation and ecosystem changes. The session will also explore post fire management strategies and policies that aim to improve the recovery and resilience of ecosystems to fire.
