The Ice Stupas are revolutionary water storage structures developed in the harsh heights of the Himalayas, particularly in Ladakh, to alleviate water shortages in dry seasons. Local engineer and environmentalist Sonam Wangchuk developed this innovative concept. In the winter months, water is diverted from small streams and distributed via artificial towers. There it freezes into massive ice cones, the Ice Stupas. These impressive structures then slowly melt in the warmer months and supply the surrounding communities with much-needed water.

The idea of the Ice Stupas has also attracted attention outside Ladakh. For example, an Ice Stupa has been erected for the sixth time in the Engadin, more precisely at the Diavolezza valley station. This not only serves as an impressive demonstration of sustainable water resources, but also as an example of how ideas and innovations can be shared across geographical borders to create a more sustainable future together.
In November 2016, Europe's first Ice Stupa was created in Val Roseg, at the same time as its inventor, Sonam Wangchuk, was honoured with the coveted Rolex Award for Enterprises in Hollywood. This achievement led to the founding of the glaciersalive.ch association and helped to raise awareness of the Ice Stupa movement. In collaboration with Lucerne University of Applied Sciences and Arts, further Ice Stupas are to be built at the Diavolezza valley station over the next few years. This is part of a common goal to raise public awareness of water conservation and to support communities in Ladakh through fundraising. At the same time, the development and testing of an automatic control system is also aimed at a reverse technology transfer, which should enable farmers in Ladakh to cope with even drier conditions in the future.
Visit the Ice Stupa at the Diavolezza valley station in the Engadin to find out more about this fascinating technology. Guided snowshoe tours with glaciologists and Ice Stupa specialists will take place on 28 March and 3 April 2024 at 9.30 am. Registrations are accepted until 12.00 noon the day before at Pontresina Tourist Information on 081 838 83 00.
