Union Minister Shri Nitin Gadkari Addresses Workshop on Landslide Mitigation for Resilient Hill Roads

**Executive Summary** Union Minister Shri Nitin Gadkari addressed a workshop on April 30, 2026, focused on implementing landslide mitigation measures for resilient road infrastructure in the geologically fragile Himalayan region. The session highlighted the adoption of advanced technologies and strategic collaborations with various technical institutions to address natural disaster risks. A significant policy decision was announced to prioritize slope stabilization before the commencement of any new road construction in hilly terrains. **Key Points / Main Content** * **Policy and Strategic Shift** * Mandatory prioritization of slope stabilization works before starting actual road construction in hilly areas to ensure long-term durability and safety. * Focus on building climate-resilient highways capable of withstanding landslides, cloudbursts, and earthquakes. * **Technological Advancements** * Utilization of LiDAR and Unmanned Aerial Vehicles (UAVs) for extensive topographical surveys. * Integration of landslide susceptibility mapping and historical data into the preparation of Detailed Project Reports (DPRs). * Deployment of InSAR-based landslide monitoring and early warning systems, including a 100-km pilot stretch on the Chardham route in Uttarakhand. * Development of guidelines for hillslope instability using real-time monitoring systems in collaboration with IIT Roorkee. * **Strategic Institutional Collaborations** * **THDC India Limited:** Specialized landslide treatment in Uttarakhand and Arunachal Pradesh. * **Defence Geo-informatics Research Establishment:** Focused on geo-hazard mitigation. * **Geological Survey of India:** Geological investigations and data sharing for tunnel and corridor projects. * **National Institute of Rock Mechanics:** Geotechnical scrutiny, design validation, tunnel safety audits, and instrumentation monitoring. **Impact Analysis** **Ministry of Road Transport & Highways and Construction Agencies** **Impact:** Project planning and execution workflows must change to accommodate pre-construction stabilization requirements. **Action Required:** Integrate advanced survey technologies (LiDAR/UAVs) and susceptibility mapping into the DPR preparation phase and ensure slope stabilization is completed before main construction begins. **Technical and Research Institutions (IIT Roorkee, NIRM, GSI, DGRE)** **Impact:** These bodies are now central to the safety and design validation process of hill road projects. **Action Required:** Collaborate on data sharing, conduct safety audits, and develop standardized guidelines for real-time monitoring and geotechnical scrutiny. **Regional Residents and Commuters** **Impact:** Improved safety and reliability of transport corridors in landslide-prone areas, particularly along the Chardham route. **Action Required:** Utilize early warning systems provided by InSAR-based monitoring to enhance travel safety during periods of instability.
