Floods, debris flows, landslides and avalanches are the most frequent hazards affecting the highest number of people in mountain regions  . Landslides count among the deadliest hazards globally, with over 150,000 reported fatalities for the period 1995-2014 . There is high confidence that the number of fatalities from landslides has increased globally over the past 20 years , but there is limited evidence that this is due to changes in landslide event frequency and/or magnitude. Infrastructure expansion on unstable terrain can increase disaster risk . A study from western Nepal concludes that the exposure of people and infrastructure to hazards has been the main cause of disasters . Decreasing numbers of fatalities from disasters resulting from decreasing vulnerabilities have been reported in Europe and North America  . Evidence from Africa suggests that disasters from climate-induced natural hazards in mountain areas are often due to droughts, pests and changes in rainfall and associated impacts on smallholder farmers' agricultural livelihoods .
