The Nilgiris hills are layered with Archaean-aged charnockite and gneiss, overlain by lateritic soils. The soils and bedrocks receive an abundance of rainfall during the monsoons from October through December and that is when most landslides occur, largely in the form of debris/earth slides or flows. Landslides cause casualties and significant damage to properties and environment and multiple studies have been carried out in the Nilgiris hills to assess risks, look at preventive measures and consequences related these natural events.
The key project working on this issue is called LANDSLIP (LANDSLIde Multi-Hazard Risk Assessment, Preparedness & Early Warning in South Asia: Integrating Meteorology, Landscape and Society), a collaboration between Keystone foundation and Practical Action Consulting which started in 2017. The aims and objectives of the project are to integrate a novel and useable landslide risk assessment & Early Warning System (EWS) in a multi-hazard framework, to co-produce with and deliver to appropriate stake-holders useful and accessible tailored information as well as disseminate LANDSLIP project knowledge to the broader South Asia regions.
