As Europe endures another scorching summer, the continent's water resources are under unprecedented strain. While the European Union as a whole uses only 5.8% of its freshwater—drawn from glaciers, groundwater, rivers, and lakes—this average masks stark disparities that are both striking and concerning.
According to data from Eurostat and the European Environment Agency (EEA), several member states are operating well beyond sustainable limits. A country enters the warning zone when it uses 20% of its water. Cyprus, however, has consumed 72% of its freshwater resources annually, with a summer peak of 92%. The Mediterranean island is effectively in constant emergency mode.
Earlier this year, Cypriot authorities urged residents to reduce daily water use by 10%—roughly equivalent to two minutes of tap time. But the country's rapidly growing population compounds the challenge. The government has been racing to install desalination plants to secure drinking water, especially ahead of the tourist season. The outgoing Cypriot Presidency of the Council of the European Union made addressing this crisis a top priority.
Mediterranean Hotspots and Beyond
Malta follows closely, with an annual water usage rate of 33%, which surges to 67% during the summer months. Other southern European countries also face severe seasonal stress: Greece (37%), Romania (34%), Portugal (31%), Italy (27%), and Spain (26.5%) all sit well inside the warning zone during the hottest months. The IPMA has warned of 43°C heatwaves and tropical nights across mainland Portugal, further straining water supplies.
The EEA warns that climate change and drought events will likely intensify the "frequency, intensity, and impact" of water shortages at least until 2030. A separate EEA report, Overheated and Underprepared, found that roughly one in ten EU citizens struggles to access enough safe and clean water. The problem is most acute in Cyprus (36.5%) and Greece (31.5%).
Interestingly, several countries with poor water access—including Bulgaria, Hungary, Croatia, and Ireland—do not experience particularly high rates of freshwater exploitation. This suggests that the issue may be less about water scarcity and more about ageing infrastructure and shortcomings in supply systems. Meanwhile, the Swiss glaciers have hit record early melt as Europe's heatwave accelerates ice loss, highlighting the broader environmental toll.
As the heatwave continues to move east, the debate over adaptation measures intensifies. The air conditioning debate heats up, with some cities like Berlin deploying water cannons to cool the public. But for countries like Cyprus and Malta, the challenge is existential: securing enough water for both residents and the millions of tourists who flock to their shores each summer.
