In early June 2025, the serene landscapes of Sikkim were marred by a catastrophic landslide, underscoring the region's vulnerability to natural disasters. Triggered by incessant rainfall, the landslide not only claimed lives but also disrupted the socio-economic fabric of the state. The Calamity Unfolds On June 1, 2025, a massive landslide struck Chaten in North Sikkim's Lachen district. This disaster led to the tragic deaths of three Indian Army personnel and left six others missing, including a commanding officer and his family. The landslide, induced by relentless rains, buried an army post, highlighting the perils faced by military installations in high-altitude, disaster-prone areas. Simultaneously, the Mangan district witnessed severe devastation. The collapse of a newly constructed suspension bridge at Sanklang severed the main connection to North Sikkim and Dzongu, isolating communities and hampering rescue operations. The Singtam-Dikchu road also became inaccessible due to the landslide, though a temporary diversion was established through Dochum . Humanitarian Crisis and Rescue Efforts The landslide's aftermath saw over 1,200 tourists stranded in the Mangan district, with more than 100 still awaiting rescue. The National Disaster Response Force (NDRF) deployed a 23-member team from Gangtok to Chhaten to undertake search and rescue operations. In Lachung, over 200 stranded tourists were successfully evacuated, with efforts ongoing to rescue the remaining individuals . The relentless rains not only disrupted road connectivity but also led to power outages, mobile network disruptions, and food shortages in several areas. The collapse of infrastructure and the isolation of communities underscored the urgent need for efficient disaster management and resilient infrastructure in the region. Government Response and Relief Measures Sikkim's Chief Minister, Prem Singh Tamang, promptly announced an ex-gratia payment of ₹5 lakh to the families of those who lost their lives in the landslides. He also assured the rebuilding of homes destroyed by the calamity and the provision of half-acre cultivable land to families whose homes were completely swept away . Acknowledging the severe losses, the Chief Minister requested immediate funds from the central government to aid the response efforts. Prime Minister Narendra Modi reviewed the worsening flood situation in the northeastern states, including Sikkim, and assured all possible assistance and support from the central government during this crisis. Environmental Concerns and Infrastructure Vulnerability The landslide also brought to light the environmental challenges faced by Sikkim. The Teesta-V hydropower station, operated by the National Hydroelectric Power Corporation (NHPC), suffered significant damage, with estimated losses around ₹327.67 crore. This incident, coupled with the damage from the glacial lake outburst flood in October 2023, raises questions about the sustainability and safety of such projects in ecologically fragile regions. Former Environment Minister and Congress leader Jairam Ramesh criticized the unplanned construction and proliferation of hydel projects in the state, emphasizing their detrimental impact on Sikkim's ecology. He highlighted the frequent blockages on National Highway 10 (NH-10), a vital link for the region, and the need for a comprehensive review of infrastructure projects in the area. Preventive Measures and Future Preparedness In a proactive move, the Gangtok district administration imposed a ban on new earth excavation activities from June 1 to September 30, aiming to mitigate the looming threat of landslides during the monsoon season. This decision aligns with broader efforts across the Northeast to address environmental and safety challenges posed by the monsoon. Furthermore, the Ministry of Road Transport and Highways acknowledged the frequent blockages on NH-10 and sanctioned funds for landslide mitigation works covering multiple locations. These initiatives reflect a growing recognition of the need for sustainable development and disaster-resilient infrastructure in the region. The devastating landslide in Sikkim serves as a stark reminder of the delicate balance between development and environmental preservation. As the state grapples with the aftermath, it is imperative to prioritize sustainable infrastructure, robust disaster management systems, and environmental conservation to safeguard the lives and livelihoods of its residents. The resilience and collective efforts of the government, armed forces, and local communities offer hope for recovery and a more secure future for Sikkim.
