SHIMLA: Himachal Pradesh has recognized 67 weak glacial lakes, together with a number of in distant, high-altitude areas, and is working to ascertain early warning programs for 4 of essentially the most weak lakes in Kinnaur and Lahaul-Spiti, Particular Secretary, Catastrophe Administration, Pushpinder Rana, stated on Saturday.The state is monitoring the recognized lakes utilizing satellite tv for pc imagery and different scientific knowledge to detect modifications that would heighten the chance of glacial lake outburst floods (GLOFs).It’s also exploring technical options to put in sensors and transmit real-time knowledge from distant places the place typical communication networks are unavailable.Rana advised information company ANI that the identification of numerous weak glacial lakes was a trigger for concern, particularly as current disasters within the Himalayas have proven that main incidents can happen with out typical warning indicators similar to heavy rainfall.“Quantity bada hai, chinta ka vishay toh hai hello (The determine is large, it is a matter of concern). On the State Centre for Local weather Change, we now have recognized 67 such lakes that are above 10 hectares in space. We’re analysing them by means of satellite tv for pc and different knowledge to see whether or not any such scenario is creating in them,” he stated.Glacial lake outburst floods (GLOFs) happen when water saved in or round a glacial lake is instantly launched, sending giant volumes of water downstream.These occasions can set off flash floods, injury infrastructure and pose a critical risk to settlements in downstream valleys.Rana stated current incidents within the Himalayan area had highlighted the issue of predicting such occasions solely on the idea of rainfall forecasts.He stated the state was due to this fact searching for technological options that would enable weak lakes to be monitored repeatedly, notably these located in inaccessible terrain.“Till we discover an progressive strategy to transfer ahead on this, we won’t be able to take efficient steps concerning them,” Rana stated.Rana stated Himachal Pradesh had submitted a proposal to the Nationwide Catastrophe Administration Authority (NDMA) to ascertain early warning programs for weak glacial lakes.He stated work had been taken up on 4 lakes in Kinnaur and Lahaul-Spiti underneath the Nationwide Landslide Mitigation Programme, with a concentrate on strengthening monitoring and early warning capabilities.The lakes embody Parchu Lake and weak places within the Sangla-Kinnaur area, in addition to websites in Lahaul-Spiti.The proposed programs are supposed to detect probably harmful modifications in lake situations and talk warnings to authorities and downstream populations.Nevertheless, Rana stated set up of such programs at high-altitude places remained a serious technological problem.“The early warning system is a technical problem. The issue is that these places are in very distant areas the place there isn’t a community connectivity. The place will the sensors be put in, how will they be put in and the way will the information be transferred? These are the challenges,” he stated.The state is working with the Centre for Improvement of Superior Computing (C-DAC) to develop technological options to handle these challenges.Rana stated the state would start putting in an early warning system at Dipang Ghat as soon as it receives closing approval from the NDMA.Alongside early warning programs, the federal government is endeavor Excessive Flood Degree (HFL) marking in downstream areas that would probably be affected by a sudden launch of water.“The Excessive Flood Degree marking within the downstream areas that may very well be affected can also be being taken up at Dipang Ghat. The method is underway,” Rana stated.Rana stated common monitoring and group consciousness would kind an essential a part of the preparedness technique round weak lakes.“The concept is that we’ll transfer ahead in direction of an early warning system. The Excessive Flood Degree marking and common monitoring may also be deployed at such places,” he stated.The state’s strategy can also be linked to scientific research of Himalayan glaciers and glacial lakes utilizing satellite-based observations.Specialists finding out the Himalayas have more and more used distant sensing and satellite tv for pc imagery to trace modifications in glaciers and glacial lakes, notably in high-altitude areas which might be troublesome or hazardous to entry on the bottom.Satellite tv for pc knowledge enable researchers to check modifications in glacier extent and lake formation throughout completely different Himalayan basins over time. Research in Himachal Pradesh have examined basins such because the Sutlej and Spiti, documenting modifications in glacier space in addition to the quantity and measurement of glacial lakes.The provision of higher-resolution satellite tv for pc imagery has additional improved the detection of smaller water our bodies and enabled extra exact monitoring of modifications of their extent.Such scientific monitoring is essential as a result of a rise within the quantity or measurement of glacial lakes, modifications in surrounding glaciers, unstable moraine dams and different bodily modifications can point out evolving dangers, though particular person lakes require site-specific evaluation earlier than being categorised as an imminent GLOF risk.Rana stated satellite tv for pc knowledge would due to this fact stay an essential element of the state’s monitoring technique.Rana stated GLOF dangers couldn’t be addressed by Himachal Pradesh or India in isolation as a result of the Himalayan river programs and glacial landscapes lengthen throughout worldwide boundaries.“There are round 1,000 such lakes inside the Indian aspect of the border, and to know what is occurring and the way it’s taking place, we positively want worldwide information and alternate,” he stated.He harassed the significance of sharing details about developments in high-altitude areas and upstream river programs, notably the place modifications might have penalties for downstream populations.The problem assumes added significance for Himachal Pradesh as a result of a number of main river programs originate in or go by means of high-altitude Himalayan terrain.Rana stated the state was additionally strengthening its broader catastrophe data and response mechanism.The emergency helpline 1077 is obtainable to report disasters and potential hazards, whereas Emergency Response Centres at each the district and state ranges function around the clock.He stated data acquired from completely different sources, together with the India Meteorological Division, is assessed and verified earlier than authorities take motion.As Himachal Pradesh faces rising dangers from GLOFs, flash floods, cloudbursts, landslides and different climate- and weather-related hazards, officers say a mix of satellite tv for pc surveillance, scientific assessments, ground-level monitoring, early warning programs, HFL mapping and speedy emergency response can be essential to decreasing dangers in weak Himalayan valleys.
