Europe is Bracing for (Another) Devastating Drought

The drought in parts of France is so bad right now that some authorities have banned new home-building projects-for the next four years. Despite a severe housing shortage in France, new homes just aren't worth the drain on water resources that construction, and eventual new residents, would cause, say nine communes in the south of the country.
It's just one of many signs that Europe is running dry. "What we are looking at is something like a multiyear drought," says Rohini Kumar of the Helmholtz Centre for Environmental Research in Germany. Unusually low rainfall and snowfall was recorded this winter not just in France but also in the UK, Ireland, Switzerland, and parts of Italy and Germany. The current predicament follows European droughts in 2018, 2019, 2020, and 2022.
Last summer, drought exacerbated by record temperatures around the continent was in the headlines. The subsequent dry winter has meant that many aquifers-places underground that retain water-and surface reservoirs have not had a chance to recover. Now, summer beckons once again, and experts who spoke to WIRED are worried that a severe water shortage could threaten lives, industry, and biodiversity in a big way.
The European Drought Observatory tracks indicators of drought across the continent, including from satellite measurements, and suggests that vast regions are far drier than they should be. "Honestly, all over Central Europe, this issue, it's a widespread problem," says Carmelo Cammalleri at the Polytechnic University of Milan.
He estimates that reservoirs in France and northern Italy are about 40 to 50 percent lower than they should be. The longest river in Italy, the Po, is 60 percent below its normal levels. Not only that, there is roughly half the usual snow on the Alps than would be expected for this time of year. That's a huge problem, because much of Central Europe relies on meltwater from these famous mountains every spring. "The Alps are known as the water towers of Europe for a reason," says Cammalleri.
