Abstract Submission

Kerala, a coastal state, is located in the southwest of the Indian subcontinent. It lies between the Western Ghats in east, Arabian Sea in west, Karnataka in north, and Tamil Nadu in south and east. According to 2011 census, Kerala is home to 3.45 crore people. Topographically, the land area of the state has been divided into 3: highlands, midlands and lowlands. Even though the state has some 580 km of coastline, 29.65% is under forest cover. The Western Ghats run through 13 districts except for Alappuzha. These Western Ghats comprise rocks of the Archean period. However, the topsoil formated is thin and hence it is prone to Landslides. The climate of Kerala, as per Koeppen’s classification, is tropical monsoon with seasonally excessive rainfall and hot summer except over Thiruvananthapuram district. In recent years, during the months of Monsoon, the state is more vulnerable to floods and landslides.

Over the last 5 years, the frequency of deadly landslides has been considerably increased especially in the Western Ghats. From 1st to 20th August 2018, the State has received around 771 mm of rain. This torrential rainfall triggered 341 landslides in 10 districts. The Idukki district alone was impacted by 143 landslides (UNDP, 2018). In 2019 there were more than 80 landslides in eight districts over three days and the death toll crossed 120. The slide in Puthumala in Wayanad district resulted in 17 deaths. In 2020, a single landslide in Pettimudi caused the death of more than 70 people.  On 15th October 2021, Kottayam and Idukki districts received 164.5 mm and 305.5 mm of rainfall respectively and triggered landslides and floods which resulted in 26 casualties.

Landslides in Kerala

Landslides are the movement of a mass of rock, debris, earth down a slope. Landslides can be initiated in slopes already on the verge of movement by rainfall, snowmelt, changes in water level, stream erosion, changes in groundwater, earthquakes, volcanic activity, disturbance by human activities, or any combination of these factors (USGS). Landslides are triggered usually when the intensity of the rainfall increases to 200mm in 24 hours. According to NCESS (2010), 1848 km2 (4.71%  of landmass) of the state falls under high landslide-prone area and 3759 km2 (9.77% of the landmass)  lies under the low landslide-prone category. Devikulam, Vythiri, Nilambur, Mannarkad and Ranni are the most landslide prone taluks in the state.

Objectives of the Conference
  • Identify the best practices and engineering solutions available across the globe for landslide mitigation.
  • Develop best locally adaptive practices for landslide mitigation and management of Kerala State.
  • Enhance the linkages between administration and R&D institutions in the domain of detection and early warning of landslide hazards.
