Climate and population: risk exposure to precipitation concentration in mainland Spain (1950-2010)
The term risk exposure combines the notions of natural hazard and the human exposure to that hazard. Spatial and temporal variations in risk exposure, therefore, can be caused by changes in hazard, in exposure, or both. In this work a novel methodology for computing and representing risk exposure a...
