The video explores the challenges faced by Arctic communities, particularly in Longyearbyen, due to avalanches caused by heavy snowfall. It highlights the implementation of physical barriers and a technological solution to mitigate these risks. The technological solution involves an early warning system developed by a telecom firm and a university, which uses snow sensors to measure snow depth accurately. These sensors are low-cost, have long-lasting batteries, and transmit data every 10 minutes over a 4G network. This data is then analyzed to predict avalanche risks, helping emergency teams make timely evacuation decisions. The system has been effective, with no accidents reported since 2017. However, climate change is increasing the risk of avalanches, as the region is warming six times faster than the global average. The technology is also being adapted for other applications, such as measuring water volume for hydroelectric power production, demonstrating its versatility and potential for broader use in managing natural hazards.
