Water scarcity and management issues persist across Europe, characterized by extreme weather volatility. In August 2026, Italy and Switzerland reached an emergency agreement to address critical shortages in Lago Maggiore. To support the Po River basin—where rice production in Piedmont, Novarese, Lomellina, and Milanese regions faces a 70% water deficit—water discharge from Lake Lugano at Ponte Tresa will increase from 3 to 8 cubic meters per second. While this provides relief to Lago Maggiore, Swiss authorities in Ticino report that hydroelectric reservoir levels are at a decade low. Simultaneously, the region is experiencing a cycle of drought and sudden, destructive flooding. While Lombardy maintains a 52% deficit in water reserves, recent storms in Valtellina have provided some relief to Lake Como, which has risen to -19 centimeters. However, Lake Maggiore remains critical at -40 centimeters. Heavy rainfall has triggered widespread emergencies across Northern Italy. In the Brescia and Bergamo provinces, landslides and river flooding have caused significant damage. The Oglio river overflowed in Malonno, and a landslide in the Val Rabbia destroyed the bridge in Rino di Sonico, leading to the evacuation of dozens of residents. In Valcamonica, the collapse of infrastructure and landslides have isolated several communities, necessitating emergency transport plans. As of late August, emergency services have conducted approximately one thousand interventions to manage the crisis. In the Bergamo area, roughly 250 people were evacuated from the San Simone campsite in Isola di Fondrano due to the dual threat of rising river levels and imminent landslides. Civil Protection has issued orange alerts for thunderstorms and hydrogeological hazards across Lombardy, Liguria, Tuscany, and Friaul-Julisch Venetien. In Ticino, despite the hydrological instability, viticulturists report a sense of ‘cauto ottimismo’ (cautious optimism). ~~Although the season has been marked by high temperatures and drought, early harvests suggest the yield could be among the best in two decades, despite smaller berry sizes.~~
