'When facing a new fire-prevention project design in the WUI we consider three different scales: the landscape (macro-scale), the surroundings and interior of the settlement (meso-scale) and the surroundings of the house (micro-scale). This trans-scalar approach allow us to better identify and prioritize actions and address appropriate responsibilities for their implementation. Today typically a ‘defensible space’ around the house has been considered as the main land transformations for structures protection in the micro scale. On the other hand firebreaks surrounding settlements are typically designed and cleared to provide firefighting opportunities but, to which extent these are rat traps? Indeed, there are several situations in which these measures may be not enough and further transformations may be needed to ensure firefighters safety and firefighting opportunities. In this sense, an overview of the strategies at landscape level (macro-scale) are provided. Also, and specially, an insight of the concept and importance of the meso-scale transformation is given, with some examples. This entails the extension of the ‘defensible space’ concept to a larger area outside and inside of the settlement, including fuel transformation, accessibility, and water availability. Relationship between scales are underlined and, more specifically, the importance of the transformation of micro-scale in the design of a robust meso-scale, leading to a fire-adapted WUI structure. Some tools for the identification and dimension of such meso-scale are explained, with real examples as developed in Spain.'
