Swiss Tap Opens for Drought-Stricken Lake Maggiore

Switzerland has initiated an emergency measure by increasing water releases from Lake Lugano into Lake Maggiore to alleviate severe drought conditions affecting northern Italy. The discharge rate will rise from 3 to 8 cubic meters per second, a decision made urgent by the critical water levels in Lake Maggiore and the immediate needs of rice cultivation in Piedmont and Lombardy.

This intervention, discussed within an Italian-Swiss bilateral body, highlights Italy's broader water scarcity crisis. Many regions, including Piedmont, Lombardy, Veneto, and the Marche, are experiencing significantly reduced surface water flows, impacting not only agriculture but also drinking water supplies. Some municipalities are resorting to water tankers to supplement reservoirs.

The situation is compounded by record-high temperatures that increase water loss through evapotranspiration. The Po River's flow has dropped to critical levels, increasing the risk of saltwater intrusion in the Po Delta and straining ecosystems, farming, and water infrastructure.

Distributing scarce water resources has become a major challenge, forcing difficult decisions between agricultural irrigation, maintaining river flows, supplying households, and supporting ecosystems. This complex issue requires sophisticated agreements between regions and countries to manage water availability, which is increasingly variable.
