Abstract:
Rainfall-triggered landslides are part of a natural
process of hillslope erosion that can result in catastrophic
loss of life and extensive property damage in mountainous,
densely populated areas. As global population expansion on
or near steep hillslopes continues, the human and economic
costs associated with landslides will increase. Landslide hazard
mitigation strategies generally involve hazard assessment
mapping, warning systems, control structures, and regional
landslide planning and policy development. To be sustainable,
hazard mitigation requires that management of natural
resources is closely connected to local economic and social
interests. A successful strategy is dependent on a combination
of multi-disciplinary scientific and engineering approaches,
and the political will to take action at the local
community to national scale.
