EarthzineArticles, Disasters, Earth Observation, OpEd, Original, Wildfires Theme

For all the recent progress in Earth Observation technologies, wildfires remain a serious problem that poses ever-increasing challenges to our ingenuity. Minimizing their often-dramatic environmental and human impacts will require a smart combination of technology, political decision, and willingness to accept changes in our own individual and collective options as societies. In order to show how fire hazard is threatening many parts of the world on a recurrent basis, details are provided on the recent severe 2013 fire season in Portugal, along with background information on remote sensing of wildfires and related disaster risk management challenges.
