Water has long been considered one of Europe’s most reliable natural resources. However, rising temperatures, prolonged droughts and changing precipitation patterns are placing increasing pressure on freshwater supplies across the continent. What was once viewed primarily as an environmental issue is now becoming an economic, agricultural and energy security challenge.
According to the European Environment Agency (EEA), approximately 20% of Europe’s land area and 30% of its population experience water stress every year. Climate change is expected to intensify these pressures, particularly in Southern and Central Europe, where droughts are becoming more frequent and severe.
As the European Union advances its Fit for 55 objectives, sustainable water management is emerging as a critical component of climate resilience.
Why is water becoming scarcer?
Climate change is altering Europe’s hydrological cycle. Higher temperatures increase evaporation from soils, rivers and reservoirs, while changing rainfall patterns lead to longer dry periods followed by more intense rainfall events. Heavy rainfall often results in rapid runoff rather than replenishing groundwater reserves.
The Intergovernmental Panel on Climate Change (IPCC) reports with high confidence that drought frequency and severity have increased in several European regions since the mid-20th century. Between 1976 and 2006, drought-related losses in the European Union were estimated at approximately €100 billion, and the economic impacts have continued to grow in recent years.
Agriculture remains the largest consumer of freshwater in many Member States, accounting for up to 60% of total water use in some southern European regions during summer. MDPI
Water and Europe’s economy
Water shortages affect far more than agriculture.
Hydropower production declines when river flows are reduced, cooling water becomes less available for thermal and nuclear power plants, and low river levels disrupt inland shipping. During the 2022 European drought, water levels on the Rhine River fell so low that cargo transport was significantly restricted, affecting supply chains and increasing transport costs across several industries.
The European Commission’s Joint Research Centre (JRC) estimates that drought-related economic losses could exceed €65 billion annually by the end of the century under high-emission scenarios if adaptation measures remain limited. SustainabilityOnline
Water-intensive industries, including food production, chemicals, semiconductors and data centres are also becoming increasingly exposed to water-related risks. Montclima

What can be done?
Addressing Europe’s water challenge requires both technological innovation and better resource management.
Key measures include:
- modernising irrigation systems to reduce agricultural water consumption;
- restoring wetlands that naturally store water during wet periods;
- increasing rainwater harvesting in urban areas;
- improving wastewater treatment and water reuse;
- reducing leakage in drinking water infrastructure;
- integrating smart monitoring systems to optimise water use
The European Commission estimates that approximately 25% of treated drinking water is lost through leakage in some distribution networks, highlighting significant opportunities for efficiency improvements. Europa.eu
Water and Fit for 55
Although the Fit for 55 package primarily focuses on reducing greenhouse gas emissions, many of its measures indirectly strengthen water resilience.
Improving building energy efficiency reduces water use associated with energy production, while expanding renewable energy particularly solar and wind can lower dependence on thermoelectric power generation, which often requires substantial cooling water.
Nature-based solutions, including urban green infrastructure and ecosystem restoration, also support water retention while helping cities adapt to both droughts and extreme rainfall.
Together, these measures demonstrate that climate mitigation and climate adaptation are increasingly interconnected. Ecochain
Looking ahead
Population growth, urbanisation and rising temperatures are expected to increase competition for freshwater resources across Europe. The OECD projects that global water demand could rise by 20-30% by 2050, while climate change is likely to make water availability more variable in many regions.
For businesses, understanding water-related physical climate risks is becoming an increasingly important element of sustainability strategies and climate disclosures under frameworks such as the Corporate Sustainability Reporting Directive (CSRD).
For policymakers, investing in resilient water infrastructure will be essential for protecting public health, food production and economic stability.EEA
Conclusion
Water is rapidly becoming one of Europe’s defining climate challenges. While the continent is unlikely to face uniform water scarcity, regional differences are expected to become more pronounced, increasing pressure on agriculture, industry, energy systems and urban development.
Reducing greenhouse gas emissions remains essential for limiting long-term climate change, but adaptation measures that improve water efficiency and resilience are equally important. By combining the emissions reduction objectives of Fit for 55 with sustainable water management and climate adaptation, Europe can better prepare for a future in which water is an increasingly valuable and strategic resource.
