Exclusive: UCL scientists find large swathes of southern Europe are drying up, with ‘far-reaching’ implications
Vast swathes of Europe’s water reserves are drying up, a new analysis using two decades of satellite data reveals, with freshwater storage shrinking across southern and central Europe, from Spain and Italy to Poland and parts of the UK.
Scientists at University College London (UCL), working with Watershed Investigations and the Guardian, analysed 2002–24 data from satellites, which track changes in Earth’s gravitational field.
Because water is heavy, shifts in groundwater, rivers, lakes, soil moisture and glaciers show up in the signal, allowing the satellites to effectively “weigh” how much water is stored.
The findings reveal a stark imbalance: the north and north-west of Europe – particularly Scandinavia, parts of the UK and Portugal – have been getting wetter, while large swathes of the south and south-east, including parts of the UK, Spain, Italy, France, Switzerland, Germany, Romania and Ukraine, have been drying out.
Climate breakdown can be seen in the data, the scientists say. “When we compare the total terrestrial water storage data with climate datasets, the trends broadly correlate,” said Mohammad Shamsudduha, professor of water crisis and risk reduction at UCL.
