Editorial statement
This paper addresses the urgent challenge of managing post-wildfire flood risk as climate-driven disasters intensify across Europe. Using the 2018 Kineta flood in Greece as a case study, it provides the first clear evidence that low-cost protective measures—costing only a small fraction of the actual damages—could have prevented millions in losses, demonstrating strong cost-effectiveness and tangible flood-mitigation benefits. The findings have important implications for public safety, urban planning, and disaster-risk policy, supporting a broader shift from reactive response to proactive, resilience-focused climate adaptation, particularly in fire-prone Mediterranean regions.
Short summary
Wildfires can exacerbate flood risks, as seen in a Greek town where heavy rain caused significant damage following a recent fire. This study examined how simple, low-cost protection measures, such as Log Erosion Barriers and wooden check-dams, might have mitigated the damage. Using models and real data, we found these measures could have lowered the flood's impact by 25 % and saved millions in damage. Therefore, investing in such prevention can be cheaper than paying for repairs after disasters.
