switzerland is home to 1,400 glaciers, of which aletsch is the biggest, and it s here that we find groups of scientists developing new techniques to watch the ice and snow and monitor their retreat. glaciers are water reservoirs that we have, which is important for groundwater replation. i think this is the important fact, but also if you lose this mass, you have instability in the mountains, so you have more landslides ongoing, more erosion. it is also a cause of natural hazards, avalanches, if there s a lot of snow and rock falls and similar things, if there s not enough snow and the ground destabilises. a very important one in terms of the energy transition is the hydropower generation. hydropower generation uses the water that runs down from the mountains and if there is not enough water, they cannot generate enough power. and if there is a lot of water, a lot of snow, they actually need to know this in advance to plan the generation. for all this, we of course need to
