As extreme weather events like storms, wildfires, and floods become more frequent and severe, the need for resilience in planning is becoming more urgent. In southern Europe, countries like Portugal are experiencing a pattern where one disaster can increase the risk of another. For instance, a very wet winter can lead to more vegetation growth, which, when dried by summer heat, becomes fuel for wildfires. This complex relationship between different types of hazards is forcing planners to rethink how they manage landscapes and communities.
In 2026, Portugal faced a particularly wet February, the wettest in 47 years. This led to heavy rainfall, flooding, and falling trees across central Portugal. While the immediate effects were damaging, the long-term impact was even more concerning. Research has shown that a wet growing season can actually increase the risk of wildfires later in the year, as the vegetation dries out and becomes fuel. This means that the same rainfall that caused flooding can also create conditions that raise the risk of fire. The challenge is that these hazards are not isolated; they are linked in ways that make planning more complex.
Since the deadly 2017 wildfires in the Pinhal Interior region, Portugal has made efforts to improve landscape management and reduce risk. Initiatives like Integrated Landscape Management Areas aim to coordinate the use of land and create more resilient environments. However, challenges remain, including the dominance of eucalyptus and maritime pine forests, which are more prone to fire, and issues with land ownership and management. This winter, storms caused widespread damage, including downed trees and blocked roads, which hindered access to areas needing protection from future fires.
The connection between different types of hazards is clear. In the Pinhal Interior, efforts to repair forest roads after the 2017 fires helped prepare for the next disaster. Similarly, heavy rainfall this winter led to flooding and damage to river defenses, affecting communities and farmland. The same wet season also supported vegetation growth, which could later contribute to wildfire risk. This shows that one event can set the stage for another, and that the time between disasters is becoming shorter, making preparation more critical.
Building resilience requires a holistic approach that includes not only landscape management but also community preparedness and infrastructure design. Fire-resistant materials, defensible space around homes, and permeable surfaces can reduce vulnerability. Moreover, managing forests and waterways together is essential, as neglecting one can increase the risk of the other. As climate change continues, the ability to adapt and prepare between disasters will be crucial for protecting people and landscapes.
