The UNESCO World Heritage Swiss Alps Jungfrau-Aletsch – protecting the cultural landscape by preserving the traditional irrigation system in the Upper Valais

Traditional irrigation systems within the UNESCO World Heritage Swiss Alps Jungfrau-Aletsch (SAJA) are critical to maintaining biodiversity and cultural landscapes, yet they face decline due to agricultural changes. The Great Aletsch Glacier and iconic peaks of Eiger, Mönch, and Jungfrau form a unique natural and cultural landscape, but traditional irrigation techniques—essential for meadows and vineyards—are being replaced by modern sprinkler systems or abandoned. To address this, the project 'Preservation of Traditional Irrigation in the Upper Valais' identified at-risk areas and engaged local stakeholders to develop solutions. Proposed strategies include financial compensation, volunteer platforms, institutionalization, education, awareness campaigns, and the establishment of an Expert Commission for irrigation landscapes. These measures aim to safeguard both ecological diversity and cultural heritage in this high-altitude region.
