It all starts with the water that falls on the mountains. Since a small change in the mountains can have a major effect on lower-lying regions, for many years, mountain hydrologist Walter Immerzeel has been studying the water balance in the Himalaya.
From a 5000-metre base camp, together with his team, he collects data on precipitation, temperature, air pressure and solar power. In turn, this data provides an insight into the effects of climate change on the habitats of millions of people who are dependent on water from the Himalaya. In Moving Mountains, filmmaker Renko Douze follows the research team on one of their expeditions.
