BELALP, SWITZERLAND - SEPTEMBER 8: Stefan Mooser, who works shifts at a pharmaceutical plant and raises sheep part-time, looks at his Valais Blacknose sheep penned in a stone enclosure dating back to the Middle Ages called a Färricha at the conclusion of the annual “Schäful” sheep drive on September 8, 2024 in Belalp, Switzerland. The sheep have spent the summer grazing on high alpine meadows in the Aletschji region above the Oberaletsch and Grosser Aletsch glaciers. During the festive “Schäful,” shepherds and sheepherders gather the scattered sheep over several days and lead them to the village of Belalp, where owners take them back, either for slaughter or for winter breeding. Climate change, while it has led to increased amounts of grass for grazing, is also creating complications for the shepherds. The Oberaletsch glacier that once provided an easy means of crossing a gorge along the route has shrunk and receded, leading local authorities to blast a path into the rockface and build a suspension bridge already in the 1970s. More recently, prolonged durations of weather that is either too wet or too dry are increasing. Snow is now falling later in the year and melting later in the spring, shifting the summer grazing season. And due to the warming climate, vegetation unsuitable for the sheep is taking root at higher altitudes, pushing into the sheep’s meadows. The Swiss government, which sees alpine landscapes and traditions as intrinsic to the country’s national and cultural identity, subsidizes alpine farming heavily. (Footage by Sean Gallup/Getty Images)
