Landslides play an important role in the evolution of landforms and represent a serious hazard in many areas of the World. In places, fatalities and economic damage caused by landslides are larger than those caused by other natural hazards, including earthquakes, volcanic eruptions and floods. The Nilgiris district is located in the southern state of Tamilnadu in India, bounded on the north by the state of Karnataka, on the east by Coimbatore and Erode districts, on the south by Coimbatore district and on the west by the state of Kerala. Although most parts of Nilgiris have experienced landslides during the past 30 years, strategies for preparedness of the community and mitigation activities are lacking. Intense rainfall during the 2009 monsoon in the hilly district of Nilgiris, triggered landslides which affected road and rail traffic, destroyed buildings, caused the death of more people etc.,. In this connection to the previous landslide hazard, the study carried on landslide hazard mitigation in the district, the possibility of cost effective technology for slope stabilization, environmental and communal issues have to be addressed for the Nilgiris district and suggestion were given to defeat these issues.
