On the prevalence of Forest Fires in Spain

We study the prevalence of forest fires in Spain in the long run by computing the probability that a forest tree, as opposed to shrub or bush, will be lost to fire over the course of the year. Climate change is first shown to increase the likelihood of this event. Next, we document how risk grew dramatically from 1961 up to the democratic era (c. 1980) and has since receded to less than 2 trees lost per thousand. We bring together the socio-economic drivers identified for this trend reversal. Our finding is commensurate with the evolution of the same risk in neighboring Mediterranean countries.
