8. Landslide Mitigation

The fundamental impetus of any kind of natural hazard and risk management is an awareness of threat, a notion of responsibility and a brief that human action might reduce the risk. Various components such as susceptibility analysis, hazard and risk identification, consequence analysis, hazard analysis, and risk evaluation are included in the landslide management framework. In the present study of the Shivkhola Watershed for slope stabilization, some mitigation measures have been proposed on the basis of community wisdom assessed through perception study on people living in four landslide prone villages such as Paglajhora, Tindharia, Gayabari and Giddapahar. The value of experience depicts that Catch-water drain along the junction between road and the hill slope, jhora training, retaining wall, catchment water drainage, introduction of vegetation etc. may bring stability of slope. Besides, author’s intensive field investigation suggested that the construction and maintenance of buildings, introduction of landslide warning system, and improvement of soil strength would be taken into account as landslide mitigation measures. Here, some control works and restraint works have been taken into account to reduce landslide hazard and risk.
