Switzerland’s Persistent Drought: A Drop in the Ocean
Despite recent rainfall, Switzerland continues to face severe drought conditions, with hydrologist Manuela Brunner of the Institute for Snow and Avalanche Research (SLF) describing the precipitation as ‘a drop in the ocean’. The primary causes are the extremely dry months of April and May, coupled with a very thin snowpack in the Alps, which has left the country heading into summer with unusually low water reserves.
Across much of Switzerland, river flow—even on the largest rivers like the Rhine—is low to very low for the season. The below-average snowpack has reduced the contribution from spring snowmelt, directly impacting the main lowland rivers. This has led to exceptionally low lake and river levels, raising concerns for water supply, agriculture, and ecosystems.
According to Brunner, simple measures can prevent critical situations. These may include water conservation practices, efficient irrigation techniques, and early warning systems. The situation underscores the broader climate risks, as extreme heat and drought are the main climate risks in Switzerland. By 2050, drought could affect three-quarters of the global population and significantly reduce agricultural production, making proactive adaptation essential.
As Switzerland grapples with this persistent drought, the need for sustainable water management and climate resilience has never been more urgent. The recent rainfall, while welcome, is insufficient to alleviate the long-term deficit, highlighting the importance of long-term strategies to mitigate the impacts of a changing climate.
