The North Indian state of Himachal Pradesh has installed a state-of-the-art Glacial Lake Outburst Flood (GLOF) early warning system at the Geepang Gath glacial lake, located at an elevation of around 4,100 metres, with the aim of reducing disaster response times and saving lives.
The state has also submitted an assessment report requesting approximately ₹3,525 crore in financial assistance from the central government to address losses incurred from recent disasters. Concurrently, a Supreme Court-mandated committee is evaluating disaster risks, ecological conservation, and the carrying capacity of ecologically vulnerable zones within the region.
Dr Pushpendra Rana, Special Secretary of Disaster Management for Himachal Pradesh, stated that the government is prioritizing technology-driven early warning mechanisms, rapid emergency responses, and financial support for recovery and reconstruction efforts following repeated natural catastrophes.
He explained that the early warning system at Geepang Gath integrates three independent components: a floating buoy in the lake, an automatic weather station on the shore, and a glacier vision unit equipped with two cameras. These components monitor changes in the glacial lake and environmental conditions, transmitting alerts to relevant authorities.
“In the Himalayan context, GLOF events have become a threat. The recent incident in Nepal has underlined the need to focus more on preparedness. Several glacial lakes have been identified as potential high-risk locations in Himachal Pradesh by the NDMA and other agencies. We are already working on four lakes where the possibility of high-risk GLOF events has been identified,” he said.
Under normal conditions, the buoy sends updates every 10 minutes, but in emergencies, it begins transmitting data within 30 seconds to facilitate rapid detection of sudden changes. The weather station monitors 14 environmental parameters, while the glacier vision unit provides continuous surveillance. All systems are linked through a supercomputer-based analytical platform capable of sending mobile alerts within one to five minutes, identifying event locations and enabling immediate activation of disaster response mechanisms.
Dr Rana described the Geepang Gath installation as the first of its kind in India due to its advanced automation, integration, analytics, and mobile connectivity. Similar systems have been trialled in Sikkim and Uttarakhand, but none match the sophistication of this setup.
He noted that the system can operate on battery power for 15 to 20 days even under cloudy conditions. The initiative was developed with support from the Center for Development of Advanced Computing (C-DAC), Pune, the State Disaster Management Authority, the state administration, the Ministry of Home Affairs, and the National Disaster Management Authority.
Dr Rana emphasized the challenges posed by frequent natural disasters such as landslides, cloudbursts, and flash floods in Himachal Pradesh, saying, “Disasters have become a frequent phenomenon in the Himalayan landscape. With the help of technology, immediate information and prompt action, we can substantially reduce the response time of our disaster management mechanism and save many lives.”
Regarding the financial aid request, he said that the state’s assessment follows a thorough evaluation conducted by Himachal Pradesh and visits by an Inter-Ministerial Central Team (IMCT) to affected and vulnerable locations. The team commended the state’s data collection efforts, including spatial analysis and disaster site identification.
“We have submitted an assessment of around ₹3,525 crore in losses for this year. We hope the Government of India will release the funds soon so that repair, recovery and reconstruction work can begin immediately in the affected areas,” he said.
The losses encompass damage to infrastructure, housing, electricity and power facilities, bridges, other public assets, and hardships faced by local communities. Dr Rana highlighted that prompt financial assistance is critical for restoring infrastructure, rebuilding homes, and supporting affected populations.
He also mentioned that the Supreme Court-empowered committee is holding discussions with various departments and visiting different parts of Himachal Pradesh to study how to balance ecological conservation with development activities. The committee is examining issues such as recurring disasters, landslides, cloudbursts, tourism pressures, and the carrying capacity of environmentally sensitive areas.
“The committee is discussing with different departments how to maintain a balance between ecology, conservation and development in Himachal Pradesh. The issues include disasters, carrying capacity, tourism exceeding the limits of certain destinations, landslides, cloudbursts and other events affecting the Himalayan landscape,” he said.
Dr Rana expressed hope that the committee’s findings will prompt action by the central government and the Supreme Court, including additional funding and the deployment of new technologies to protect the Himalayan ecosystem, which he estimated to provide services valued at approximately ₹70,000 crore annually.
He underlined that safeguarding these ecosystem services is vital not only to Himachal Pradesh but to the entire Himalayan region.
On disaster preparedness, Dr Rana stated that it requires coordinated efforts involving technology, communities, administrative bodies, and government agencies. He warned that the increasing frequency of extreme events in the Himalayas necessitates improved early detection systems, public awareness, and rapid emergency response capabilities.
“It is a difficult task, but through collective efforts and an integrated approach involving technology, communities, the bureaucracy and all stakeholders, we can prepare ourselves better for disasters,” he said.
He added, “The occurrence of disasters in the Himalayan landscape is increasingly becoming a certainty. However, we must prepare our entire population and system so that whenever a disaster occurs, we can take immediate action.”
