Since 1994 there has been a 32 times increase in the number of research outputs with the keyword “landslide”. In a couple of weeks time, I have the pleasure of being one of the invited speakers at the Landslide Risk and Geoengineering (LaRGE) Conference in Queenstown, New Zealand. Ahead of that presentation, I’ve been using […]
