Abstract

Landslides are major natural and/or anthropogenic hazards that can result in major human suffering, livelihood and material losses, and environmental degradation. Worldwide, the total land area subject to landslides is about 3.7 million km2, where nearly 300 million people live, or five per cent of the world’s population (Dilley et al. 2005). Landslides can kill thousands of people. In the city of Huaraz, Peru, in 1941, a landslide transporting 10 million m3 of materials travelled more than 23 km down the Cohup Creek valley, killing between 4,000 and 6,000 people and damaging twenty-five per cent of the city (Schuster and Highland 2007). More recently, on 1 March 2010, after days of intensive rain, a landslide buried 400 people and forced the relocation of more than 5,000 families in Bududa, Uganda (Uganda Red Cross 2010). Such destructive events make landslides a major concern for potentially affected communities, as well as scientists and government officials. The combined understandings of landslides from all these actors are essential to landslide risk reduction by improving the efficacy of such activities as hazard and risk assessment, vulnerability reduction and capacity enhancement.
