Na obalo ujetih hišnih čolnov in prizemljenih potovalnih ladij: evropske reke se zaradi vročine in suše zmanjšujejo

Stranded houseboats and grounded cruise ships are highlighting a growing crisis along Europe's rivers, as prolonged heat and drought drive water levels to historic lows. In the Netherlands, one of the continent’s most flood-prone countries, officials have declared an official water shortage, elevating the national drought response to Level 2. This marks a dramatic shift from the nation’s usual struggle with excess water to a new challenge of scarcity. The government warned that reduced rainfall and increased demand are straining water resources, prompting measures such as limiting groundwater extraction and adjusting river lock operations to prevent saltwater intrusion. The Dutch Ministry of Infrastructure and Water Management stated that the situation is critical due to persistent dry spells and rising consumption. Drinking water supplies remain unaffected, though authorities urge residents to conserve usage. Climate scientist Hannah Cloke, a Regius professor at the University of Reading, described the scenario as alarming. She noted that the Netherlands declaring a water shortage in mid-July is unusual, given the typically rainy season. Cloke emphasized that this is not mere bad luck but a clear sign of climate change, as heatwaves deplete soils, lower river levels, and increase water demand simultaneously. Across Europe, similar patterns are unfolding. The continent, which has recorded some of the fastest warming rates globally, is enduring relentless heatwaves that are drying up rivers and threatening water security. The Netherlands, historically adept at managing floods, is now contending with the reverse problem. Hydrometeorologist Jan Verkade of Deltares likened the current drought to “droughts are the new floods.” He explained that the country is facing conditions typical of late summer, despite being in July, with no notable rainfall and consistently high temperatures. Water levels in key rivers such as the Rhine and Meuse have dropped to dangerously low levels, with the Rhine reaching temperatures of around 77 degrees Fahrenheit (25 Celsius). These conditions have led to the proliferation of harmful blue-green algae and mass fish deaths. Additionally, the risk of salinization is rising, as lower water levels allow seawater to encroach further inland. The Netherlands last faced a Level 2 water shortage in August 2022 and has not experienced a Level 3 shortage, defined as a “water crisis”, since 2003. Officials warn that without sustained rainfall, the situation could worsen. A spokesperson for the Ministry of Infrastructure and Water Management cautioned that continued high temperatures and low precipitation could lead to a more severe water shortage. While lessons from previous droughts in 2018 and 2022 have helped prepare the country, the ministry acknowledged that if the crisis persists through September, “more serious choices” may need to be made. Cloke reiterated that rivers retain memory of past dry periods, meaning that a few isolated rains will not resolve the issue. The impact extends beyond the Netherlands. The Rhine River, crucial for European trade, has seen water levels drop so sharply that cargo ships must reduce their loads and transport goods using multiple vessels, significantly increasing transportation costs. In July, a river cruise ship became stranded on the Rhine near Bonn, requiring a freighter to assist in pulling it into deeper waters. Although recent rains have slightly improved conditions in parts of Germany, experts caution that the threat is far from over. The Rhine’s water levels, while temporarily higher, still pose risks, and the region remains vulnerable to future dry spells.
