The event brought together 25 people with different nationalities and institutions such as the Join Research Center, the Polytechnic University, the Rey Juan Carlos University, the University of Alcalá and the Swiss Federal Institute of Forest Snow and Landscape Research, among others. The participants were researchers, professors, doctors and students who actively participated in the discussion. Link to video: https://youtu.be/hCw6QaYxjjk
Which recent climatic and socio-economic changes have affected human-driven fire regimes? It is challenging to answer this question in a global scale. That is why in this project we look at a selection of study sites. Each of them represents different fire regimes and ecosystems in order to analyse climatic, demographic, economic, legal and land-use changes, and their impact on fire occurrence from an historical point of view. The shown infography depicts the temporal evolution of wildfire legislation in the region of Galicia (one of the study areas) from 1968 to 2021. A link to the corresponding legislation has been provided for each legal reference. The infography also presents wildfire occurrence based on regional statistics for the period.
The Anthropofire viewer is a tool that allows the visualization of the main results of this project. In this context, said viewer shows the maps generated at global scale to estimate and evaluate fire risk (Figure 1). Figure 1. Components of fire risk assessment (adapted from Chuvieco et al., 2012). For the moment, the results obtained are those related to Ecological Vulnerability to Fires. The methodological scheme followed for its estimation and subsequent evaluation is the one shown in Figure 2 (link to open discussion: https://nhess.copernicus.org/preprints/nhess-2021-285/).

Fire is a natural phenomenon that has played a critical role in transforming the environment and maintaining biodiversity at a global scale. However, the plants in some habitats have not developed strategies for recovery from fire or have not adapted to the changes taking place in their fire regimes. Maps showing ecological vulnerability to fires could contribute to environmental management policies in the face of global change scenarios. The main objective of this study is to assess and map ecological vulnerability to fires on a global scale. To this end, we created ecological value and post-fire regeneration delay indices on the basis of existing global databases. Two ecological value indices were identified: biological distinction and conservation status. For the post-fire regeneration delay index, various factors were taken into account, including the type of fire regime, the increase in the frequency and intensity of forest fires and the potential soil erosion [...]
