Shimla gears up for safer future: Drone-Based LIDAR survey to combat landslide threats
In light of the growing frequency of landslides and land subsidence in Shimla, the State Disaster Management Authority (SDMA) is set to launch an advanced drone-based LIDAR (Light Detection and Ranging) survey. Running from October 21 to November 21, the survey will assess Shimla’s geographical conditions to identify areas most at risk of landslides. This crucial initiative, recommended by the Geological Survey of India (GSI), highlights the increasing concern over the city’s environmental stability.
To ensure the survey runs smoothly, all formalities for drone usage in Shimla’s no-fly zones have been completed, including obtaining permission for areas under army control. A specialized consultancy firm has been engaged to carry out the survey and is expected to submit its findings by November 21.
Deputy Commissioner Anupam Kashyap underscored the importance of the survey, emphasizing its role in assessing the instability of Shimla’s terrain and preparing for future risks. “This survey will not only enhance the safety of Shimla’s residents but will also contribute to the city’s infrastructure development,” he said, pointing to the long-term benefits of understanding the city’s topographical challenges.
The survey’s LIDAR technology uses drones to emit laser pulses that reflect off the ground, creating a detailed 3D image of Shimla’s geographical features. This precise data will help experts identify the most landslide-prone areas and uncover the underlying causes of these dangerous incidents. Equipped with this information, the SDMA hopes to implement preventive measures that could minimize future risks.
Shimla has seen a sharp increase in landslides in recent years, especially during the monsoon season when heavy rains further destabilize the fragile terrain. These landslides have caused significant damage, including blocked roads, destroyed homes, and the displacement of families. Experts point to unchecked construction on the hills and environmental imbalances as key contributors to the worsening situation.
The introduction of drone-based LIDAR technology is expected to be a game-changer in addressing Shimla’s landslide crisis. By providing a more accurate understanding of the city’s vulnerabilities, authorities will be better equipped to develop sustainable solutions that mitigate the impact of landslides. As climate change and urban expansion continue to pose challenges, such technological interventions are essential for ensuring the safety and long-term sustainability of hill cities like Shimla.
