Switzerland and Italy Redraw Alpine Border as Melting Glaciers Shift Boundaries

Switzerland and Italy have been compelled to redraw sections of their shared border in the Alps due to the ongoing effects of melting glaciers, driven by climate change. The revised boundary will affect areas near the iconic Matterhorn, one of Europe’s highest peaks, and regions close to well-known ski resorts such as Zermatt.

The Swiss-Italian border is traditionally defined by glacier ridgelines or perpetual snow areas. However, as glaciers shrink, these natural demarcations have shifted, prompting both nations to adjust the border accordingly. A draft agreement was reached in May 2023 by a joint commission, and Switzerland officially approved the changes last Friday, with Italy’s final approval still pending.

The new borders, which will impact locations like Plateau Rosa, the Carrel refuge, and Gobba di Rollin, aim to address the practical needs of both countries, particularly in terms of maintaining natural areas. The clarified boundaries will also help resolve responsibility for managing these regions as the landscape continues to evolve.

Melting glaciers have revealed a number of surprising discoveries in recent years, including the remains of a German climber missing since 1986, found last July near the Matterhorn. Such discoveries highlight the rapid rate at which the glaciers are retreating and the broader impacts of climate change on the region.
