Fueling the fires - An exploration of the drivers and the scope for management of European wildfire risk under the Shared Socioeconomic Pathways

As socio-natural phenomena, wildfires are exacerbated by climate change and socioeconomic dynamics. However, the role of socioeconomic uncertainty in shaping future wildfire risk and management remains largely neglected. Building on the notion that risk emerges at the intersection of hazard, exposure and vulnerability, we conduct an integrative literature review to identify the most significant socioeconomic drivers of wildfire risk in the European geographical and institutional context and bring this together with the Shared Socioeconomic Pathways (SSP) perspectives on plausible socioeconomic dynamics. To our knowledge, this is the first study to bridge the gap between wildfire research and socioeconomic scenarios to establish a conceptual understanding of future wildfire risk. The resulting wildfire risk scenario space has two main applications: (i) it acts as a qualitative navigator for factoring socioeconomic uncertainty in model-based wildfire risk assessments, and (ii) it sets the boundary conditions for evaluating the feasibility of management strategies. Sustainable land use practices and profitable agricultural value chains can reduce future wildfire risk (e.g. SSP1), whereas land degradation (e.g. SSP4), and socioeconomic disparities (e.g. SSP3) may increase it. As a result, challenges to future wildfire risk management differ significantly across scenarios, leading to paradoxical situations. In scenarios where vulnerability reduction has significant potential to lower risk, socioeconomic challenges reduce the feasibility of implementing the necessary measures to achieve risk reduction. Similar dilemmas may arise in the context of hazard and exposure. By considering multiple plausible futures, this paper emphasizes the importance of accounting for socioeconomic dynamics in shaping wildfire risk and keeping the design of risk management strategies open and flexible in the face of changing circumstances.
