You must be logged in to get greater insights. click here to login
Context
The landslides in Wayanad district, Kerala, caused by heavy rains during the southwest monsoon, resulted in 200 deaths and destruction of several villages.
Impact and Causes of Landslides
- Annual Landslides: Parts of Kerala experience heavy monsoon rains and landslides yearly, but the recent deadly landslides are new.
- River Dynamics: The Chaliyar river, with increased volume and force due to heavy rains, swept debris into villages, causing fatalities.
- Previous Impact: In 2020, heavy rains had already stripped upstream areas of plant cover, making the land more vulnerable to landslides.
Preparedness and Environmental Measures
- Geographical Risk: Landslide-prone areas like Idukki, Kottayam, Malappuram, and Wayanad are well-documented on risk maps.
- State's Preparedness: There is a lack of advance warning and emergency preparedness, exacerbating the impact of landslides.
- Environmental Measures: Recommendations include halting engineering projects in sensitive areas, restoring flora, and empowering expert committees to ensure sustainable development.
Mains Question
Q. Despite well-documented geographical risks and recurring monsoon patterns, Kerala continues to suffer devastating landslides. Evaluate the effectiveness of existing measures and suggest comprehensive strategies to mitigate landslide risks while balancing developmental needs.
