Europe is not only losing water. It is losing the time to hold on to it.
Record low rivers and lakes, livestock coming down from Alpine pastures weeks early, glaciers stripped of their winter reserve by the end of June, wildfires, less hydropower, and a fast-growing digital infrastructure. Europe's problem is no longer simply how much rain falls. The problem is how much of that water stays in the system after it lands.
Data as of 29 July 2026.
The key problem in this year's European drought is not only a shortage of rainfall. A warmer atmosphere sharply increases water loss through evapotranspiration, so the same rainfall deficit now produces a worse drought than it would have in a cooler climate.
At the same time, we are losing the natural reservoirs that used to hold water between the rain and the demand: glaciers, snow, wetlands, floodplains, healthy soils and groundwater.
So the real question is no longer only whether Europe will get enough rain.
The real question is: how much water will we be able to retain between the moment it falls and the moment we need it?

July 2026: several different crises, one water system
By the end of July, it is possible to connect news items that appear unrelated at first glance.
On the Rhine, low water is forcing cargo vessels to sail partly loaded. At Kaub, some could carry only about a fifth of their usual load, and freight rates from Rotterdam towards Karlsruhe rose within weeks from roughly 45 to between 60 and 70 euros per tonne.
The Danube is exceptionally low in parts of Serbia, Croatia, Hungary and Romania. Barges and tankers are restricted to a fraction of their capacity. Serbia received only about a quarter of its planned July imports of petroleum products, and the Đerdap 1 hydropower plant is running at roughly a third of its normal output.
Lake Constance reached its lowest July level in the measurement record at the end of July. The Untersee is roughly 1.5 metres below the long-term average. In northern Italy, saltwater from the Adriatic pushed 20 to 25 kilometres up the Po delta.

In Switzerland, a shortage of water and fodder is bringing livestock down from high pastures ahead of schedule.
In France and Spain, July's wildfires forced large-scale evacuations.
These are not separate stories.
A river is simultaneously an ecosystem, a transport route, an energy source, a cooling system, an irrigation supply and economic infrastructure.
When there is less water, the same disturbance simply takes a different name depending on which sector notices it.
A water planet with very little available fresh water
The view of Earth is misleading.
About 96.5 per cent of all water on the planet is salt water. Only around 2.5 per cent is fresh, and of that, roughly 68.7 per cent is locked in glaciers, ice caps and permanent snow, while about 30 per cent is fresh groundwater.
Rivers hold only a negligible share of the world's fresh water.
Civilisation is therefore not built around an unlimited store of fresh water. It is built around a relatively small part of the planetary water cycle, which has to fall in the right place at the right time, penetrate the soil, recharge an aquifer, or remain in snow, a lake, a wetland or a river long enough for us to use it.
This is precisely why the term water bankruptcy matters.
In January 2026, the United Nations University Institute for Water, Environment and Health (UNU-INWEH) published the report Global Water Bankruptcy: Living Beyond Our Hydrological Means in the Post-Crisis Era. It is not a political declaration by the UN General Assembly; it is a report by a UN University institute. Its finding, however, is unambiguous: a growing number of river basins and aquifers are losing the ability to return to their historical normal. What used to be temporary shocks is becoming a chronic condition.

In March, the UN World Water Development Report added the social picture: 2.1 billion people still lack safely managed drinking water, and women and girls together spend roughly 250 million hours a day collecting it.
Water bankruptcy therefore does not mean the planet has run out of H₂O molecules.
It means that in many places we have consumed, polluted or lost usable water reserves and natural buffers faster than they can regenerate.
"There have always been droughts." True. So why is today different?
Every time Europe experiences a major drought or heatwave, the same objection appears.
There have always been droughts.
The objection is well founded and deserves a serious answer, not ridicule.
The year 1921 was one of the worst drought years of the twentieth century, and by a wide margin. At the Uccle observation station, the twelve-month standardised precipitation index fell below −4. For comparison: the peak value in the notorious drought year of 2018 was −1.93, and in 1976 it was −2.41. The 1921 drought began in early spring and dragged on into autumn and winter. In western Europe it hit agriculture and livestock farming hardest; in central Europe, the most frequently reported impact was wildfire.

Climate reconstructions from tree rings also show older extreme events.
Claiming that "weather like this never happened before" is therefore not scientifically serious. It is in fact a poor argument, because it is verifiably false and discredits everything else that is true.
But it is equally mistaken to conclude from this that nothing has changed.
Science shows two apparently contradictory findings
In 2021, a study in Nature Geoscience found that the sequence of European summer droughts since 2015 was unprecedented over the past 2,110 years.
That same year, another group of researchers showed in Communications Earth & Environment that central Europe experienced droughts during the Spörer and Dalton minima that were longer and more severe than modern ones.
Which one is right?
Possibly both. They do not necessarily measure the same aspect of drought, with the same methods, over the same area.
But the title of the second study contains the decisive word.
Historical megadroughts were longer and more severe — and less warm.
That is the difference.
The dispute in the literature concerns the rainfall deficit. There is no dispute about the temperature.
What changed is the threshold, not the rain
The World Weather Attribution study published on 23 July 2026 showed exactly this for this year's European drought.
In the western study region, researchers found no clear long-term declining trend in April-to-June rainfall. Climate change, in other words, did not cause the shortage of rain.
What they did find was a strong increase in potential evapotranspiration — the capacity of a warmer atmosphere to draw water out of soils and vegetation.
Compared with a climate roughly 1.4 °C cooler, the extremely high evaporative conditions western Europe experienced between April and June 2026 have become about 80 times more likely, or equivalently about 7 per cent more intense. In the eastern region, for the January-to-June period, about 40 times more likely, or equivalently around 8 per cent more intense.
Soil drought has become roughly five times more likely in the western region because of anthropogenic warming, and eleven times more likely in the east.
It is not only the rain that changed. What changed is the threshold at which a lack of rain becomes a drought.
Rainfall does not have to halve for a drought to become considerably worse. It is enough that more water disappears after it falls.
And the starting point is no longer the same
Compare 1921 with 2026.
Alpine glaciers held far more ice then.
The European landscape had more wetlands and floodplains. Cities had far less impermeable surface. Irrigation was not nearly as widespread. Water use in industry, energy and tourism was different. There were no data centres.

The same meteorological drought therefore does not strike the same system today.
It is like an identical blow delivered to two people, one rested and one already exhausted.
The blow is the same. The consequence is not.
With wildfires, the historical comparison is riskier still
We often hear that it used to be just as hot and there were not this many fires.
Perhaps.
But for much of the twentieth century we simply have no data comparable to today's. Spain's systematic forest fire statistics begin in 1968, France's Prométhée database in 1973, and systematic collection at Community level only began with a 1994 regulation. European satellite mapping through EFFIS provides a comparable picture only from 2006.
The absence of a record is not a record of absence.
The claim that there were no such fires in the past is not a finding. It is a consequence of the fact that nobody counted them.
The same discipline applies in the other direction. The word "record" almost always means a record within the measurement period. The 2025 fire season was the worst in the EU in the EFFIS record since 2006 — 1,079,538 hectares burnt, nearly double the 2006–2024 average — not necessarily the worst in European history. Lake Constance's record is a record since the mid-nineteenth century, not in the history of the lake.
None of which means there is no present-day trend.
It means only that the trend must be demonstrated with data that actually exists.
The real question
The question, then, is not whether a drought also happened in 1921.
It did.
The real question is: what does a comparable drought do in today's warmer, more built-up and more water-hungry system?
There the answer is considerably less comfortable.
A rainfall deficit now meets higher evaporative demand. High temperatures now meet a greater volume of combustible biomass. A low river flow now meets a hydropower plant, shipping traffic, irrigation and the cooling needs of power stations. Groundwater now meets a larger number of users.
Droughts are not new.
What is new is the combination of the physics of a warmer atmosphere, a diminished natural reserve, and the size of the system that depends on water.
A wet winter can prepare a wildfire
This year's fires reveal another apparent contradiction.
Parts of western Europe had ample rainfall before the summer. As a result, a great deal of vegetation grew.
Then came the heat.
When a warmer atmosphere rapidly strips water from plants, abundant biomass becomes fuel.
A wet winter and a severe summer fire are therefore not opposites. Under certain conditions, the first can even be a precondition for the second.
In explaining wildfires, however, honesty is required in the other direction too. Climate is not the only factor. The European landscape is heavily shaped by human activity: the abandonment of traditional land use, the accumulation of combustible biomass, plantations of certain tree species, urbanisation and forest management practices all significantly affect fire risk.
Climate sets an increasingly dangerous backdrop.
The landscape determines what happens against that backdrop.
A river can turn into an economic problem within weeks
The water crisis is not only environmental.
It is logistical: a shallower draught means less cargo and more expensive transport.
It is energetic: less water means less hydropower and less room for manoeuvre in cooling thermal power stations.
It is a food issue: less water means less irrigation, less grass and greater pressure on fodder.
It is ecological: a smaller volume of water heats up faster, holds less oxygen and dilutes pollutants less effectively.
And it is becoming a balance-sheet risk for companies.
Slovenia is no exception.
In July, the Mura, Drava, Sava, Ljubljanica, Krka and Soča rivers, along with the upper Kolpa, all show markedly low flows. Current discharge is in places comparable to the lowest July values of the past decade.
Hydropower plants on the Drava, the Soča and the lower Sava generated 31 per cent less electricity between January and June than in the first half of 2025, and 38 per cent less than the five-year average.
At the same time, high water temperatures reduce the operating margin for cooling thermal and nuclear power stations. Because of the Krško nuclear plant, the Sava may not be warmed by more than 3 °C, nor above 28 °C in absolute terms. During June's heatwave the plant operated at full power in full compliance with its environmental limits, with the maximum warming reaching exactly the permitted three degrees.
This is not a failure of the plant. It is a property of the system: energy infrastructure is tied to the hydrological system far more closely than it appears at normal flows.
Then there is the water supply network.
According to the Statistical Office of the Republic of Slovenia, 169 million cubic metres of water were abstracted for the public water supply in 2024, 98 per cent of it from groundwater. Households consumed 77.4 million cubic metres.
Losses recorded in the network amounted to 46.6 million cubic metres. That is 13.2 per cent less than the previous year, so progress does exist. But it still represents roughly 27 per cent of all abstracted water — a volume equivalent to about 60 per cent of the entire annual consumption of Slovenian households.
A country that has written the right to drinking water into its constitution, and that depends almost entirely on groundwater for public supply, has an extraordinarily obvious reserve sitting right there.
The cheapest new source of water is often water we have already abstracted and then lost in the pipes.
Glaciers: more water first, then less
There is an intuitive trap in glacier melt.
If more ice melts, there must be more water in the rivers.
Temporarily, this is true.
While the glacier mass is large, warming increases both melt and runoff. But in doing so the glacier is spending its capital.
Once its surface area and volume shrink far enough, the system passes what is known as peak water. Even if every remaining square metre of ice melts very fast, there are fewer and fewer of those square metres.
Swiss glaciers are already very close to that point.
In 2025 they lost about three per cent of their remaining volume. Over the past decade, roughly a quarter of their volume has disappeared. More than a thousand small glaciers are already gone.
2026 delivered an even sharper signal.

ETH Zurich calculated that Swiss glaciers had exhausted their seasonal snow reserve by 29 June. From that day on, every further litre of meltwater represents a net loss of glacier mass. Only the extreme year of 2022 saw an earlier date.
More telling still is the comparison between 2003 and 2022.
Although the ice melted more intensely in 2022, less water flowed out of the glaciers.
Why?
Because there was already so much less glacier. Between those two years, around 200 square kilometres of ice disappeared in Switzerland alone.
This is a perfect illustration of why the starting reserve matters. An extreme event today hits a smaller reservoir.
And this is the moment when losing a glacier stops being merely the loss of a landscape.
It becomes the loss of a reservoir of time.
A glacier stored water in winter and released it in summer — precisely when other sources are scarcest.
Swiss cows are an economic indicator
The image of livestock coming down from the mountains early matters more than an anecdote.
By July, some Swiss farmers were already drawing on winter hay reserves. With water and fodder short on the pastures, some animals are being sold or sent for slaughter ahead of schedule.
Over four weeks, more than 31,000 cattle were slaughtered, roughly 3,500 more than in the wetter summer of 2025.
It would be wrong to write that all 31,000 animals were slaughtered "because of the drought". But the drought demonstrably accelerated the sale and culling of livestock.

Then a second dynamic kicks in. Animals arrive on the market underweight, buyers hesitate, guide prices fall, and farmers — fearing a further decline — sell faster still.
And so the chain begins:
water → grass → fodder → livestock → supply → price.
If a farmer uses in July the hay he set aside for January, a summer hydrological event relocates itself into winter.
A water problem very quickly stops being called a water problem.
Do we have enough water if it is polluted?
The quantitative debate can mislead as well.
According to the European Environment Agency's most recent comprehensive assessment, based on data from 2015–2021, only about 37 per cent of surface water bodies were in good or high ecological status, and 29 per cent in good chemical status.
The reason is interesting. A large share of the poor chemical status is caused by a small number of persistent pollutants, chiefly mercury and brominated flame retardants. Exclude those, and 80 per cent of surface waters would achieve good chemical status instead of 29.
Groundwater is in considerably better condition — but we also rely on it heavily, since it supplies two thirds of the EU's drinking water.
Water security is therefore not only a question of cubic metres.
Having polluted water is not the same as having usable water.
And having plenty of water in February is not the same as having it in July.

A constitutional right does not fill a river
Slovenia has one of the stronger constitutional provisions on water in Europe.
Article 70a establishes the right to drinking water, defines water resources as a public good managed by the state, gives priority to supplying the population, and requires that supply be provided by the state through local communities directly and on a non-profit basis.
That matters.
But a constitutional right is a rule about distribution and management, not about hydrology.
It can determine who has priority when there is not enough. It cannot increase a river's flow, restore an aquifer or repair a water main.
How far the law reaches, and where management begins, is a question in its own right. I address it in a separate piece on water ownership.
And then come the data centres
At a time of rising water stress, Europe is building a new infrastructure layer with high energy demand and, potentially, high water demand.
The IEA estimates that the European project pipeline for new data centres corresponds to roughly 130 per cent of currently installed capacity, although because of grid and other constraints it expects actual installed capacity to grow by about 70 per cent by 2030 relative to 2024. Data centres are projected to account for around a tenth of the growth in EU electricity demand to 2030.
On water, caution is required. Universal figures for "one data centre" do not exist. Consumption depends heavily on cooling technology, climate, size and operating regime.
The problem is therefore not primarily the aggregate European volume.
The problem is concentration in space and time.
Heavy consumption in a single river basin during a heatwave is not the same as the identical annual volume spread across the continent. And peak cooling demand can arrive precisely when flows are at their lowest.
This too deserves its own text.
What will the summer drought mean in autumn?
The biggest mistake would be to expect the water crisis to end along with the summer holidays.
Drought has a memory.
A river can rise within hours after heavy rain. Deeper soils, springs and aquifers take considerably longer.

The first autumn rain often has to make up the moisture deficit in the soil before groundwater recharge can begin in earnest.
A few violent September thunderstorms are therefore not the same as hydrological recovery.
For that we need longer and sufficiently moderate rainfall that has time to penetrate the ground.
The second consequence will show up in the fields.
On 27 July, the JRC lowered European yield forecasts for all major spring and summer crops. Forecasts for grain maize and sunflower were cut by roughly 6 to 7 per cent, and for winter crops by 1 to 4 per cent.
This does not mean a European food shortage.
It does mean less domestic fodder and produce, more pressure on imports, higher costs and higher prices.
Autumn is also when sowing for 2027 begins. If the soil stays too dry, sowing of winter wheat, barley and oilseed rape can be delayed and emergence will be poorer.
The third consequence is energy. If low flows persist, we enter the part of the year with rising energy demand while hydropower contributes less.
The fourth is transport. The Rhine and the Danube do not only carry tourists; they carry petroleum products, ores, grain, chemicals and industrial raw materials.
The fifth, and probably the most important, is groundwater.
If the autumn recharge season fails, a country enters the following spring not from zero but with a water debt carried over from the previous season.
And then two moderately bad years in a row can produce consequences that a single year would not.
With aquifers, this is the essential difference between an event and a condition.
We do not yet know whether autumn 2026 will be dry. Seasonal forecasts show no uniform European scenario, and in some regions the probability of above-average rainfall is actually elevated.
Good, sustained autumn rains could improve the situation substantially.
But a few severe downpours will not do it on their own.
This autumn, Europe does not only need water from the sky. It needs water that will have time to stay.
The most important change is the loss of the time lag
Europe will continue to experience very wet periods.
It will have floods and downpours.
This does not contradict water scarcity.
A short, intense downpour that runs off asphalt into the sewer and down a channelised river to the sea does not replace slow, multi-day rain or a snowpack that feeds soils and aquifers for months.
Glaciers were reservoirs.
Snow is a reservoir.
Wetlands are reservoirs.
Floodplains are reservoirs.
Healthy soil is a reservoir.
Groundwater is a reservoir.
A rainwater tank under a building is a reservoir.
Yet for the past hundred years we have built much of Europe on the opposite logic: remove water as fast as possible.
When too much falls, we carry it away as quickly as we can.
A few weeks later, when there is none, we pump it from depth, treat it to drinking quality, and use it to water lawns.
This is not primarily a technological problem.
It is an error in the architecture of the system.
What we can do immediately
In June 2025 the European Commission adopted its Water Resilience Strategy. Its objectives include better water retention, reduced network losses and an improvement of around 10 per cent in water efficiency by 2030. This is not a single legally binding ten per cent quota for every country and every sector.
But a large share of the most sensible measures requires no new European technology at all.
Treat network losses as a source of water. Sectoral metering, active leak detection, pressure management and priority renewal of the worst stretches of network.
Reserve drinking water for uses that require drinking quality. Where health and technical rules allow, rainwater or appropriately treated water can be used for irrigation, street cleaning, industrial processes and other non-potable uses. This does not mean abandoning urban trees during a heatwave — trees are cooling infrastructure for a city — but using a different source of water for them.
Large roofs must become part of the water infrastructure. In new public, commercial, industrial and multi-dwelling buildings, rainwater retention should be the standard, not an exotic extra.
Cities must become sponges, not channels. Permeable surfaces, rain gardens, sunken parks, green roofs, tree pits and similar systems can simultaneously reduce the flood peak and store water.
Water must also be retained in the wider landscape. Wetlands, floodplains, meanders, healthy soils and improved soil infiltration capacity are infrastructure.
Large new users must be given a water budget. For a data centre, an industrial plant or any other major user, the permit must state not only annual consumption but consumption on the hottest and driest day, where the water will come from, and whose abstraction is cut first if there is not enough.
Municipalities need a drought protocol before the drought, not during it. The sequence of restrictions must be set in advance and be comprehensible to residents, farmers, tourism operators and businesses.
And then we come to the individual.
Turning off the tap will not save Europe's water system.
But collecting rainwater for uses that do not require drinking quality, reducing paving and increasing permeable surfaces on your own plot, building soils with more organic matter, watering less often and more deeply, and finding your own leaks by taking a night-time meter reading are not symbolic measures. Every one of them changes the reserve, not just consumption.
The most important question a citizen can put to a municipality, however, is not: "Should I turn off the tap while brushing my teeth?"
It is:
How much water do we lose in our network?
How much rainwater do we retain in our municipality?
What is our drought plan?
And on what conditions do we permit large new users?
Subsidies for Water Storage Systems?
What if, alongside subsidising predominantly Chinese, American and German electric vehicles, the government introduced comparable subsidies for water storage systems designed to capture and reuse rainwater?
Slovenia could begin treating water in much the same way as we began treating energy a decade ago: as infrastructure worth investing in systematically at the level of individual homes, communities and municipalities.
Instead of draining rainwater from rooftops as quickly as possible into sewers and watercourses, only to use treated drinking water during the next drought to irrigate gardens, flush toilets or do laundry, the government could introduce a ten-year programme to restore traditional cisterns and build individual and community rainwater storage systems connected to separate plumbing for sanitary and outdoor use. If we take roughly 470,000 detached houses as an order-of-magnitude estimate and assume an average storage capacity of 10 m³ per property, Slovenia could create around 4.7 million m³ — or 4.7 billion litres — of decentralised water storage capacity. Since each reservoir could refill several times over the course of a year, the actual annual volume of rainwater used would be substantially higher. Based on a conservative estimate, such systems could eventually replace approximately 15–25 million m³ of drinking water each year.
Such a programme would by no means be an experiment without precedent.
In Flanders, Belgium, rainwater storage tanks are already mandatory for new buildings and major renovations. Depending on roof area, a single-family house is generally required to provide between 5,000 and 10,000 litres of storage capacity, with larger roofs requiring even greater volumes. The collected water is intended for uses such as toilet flushing, washing machines, cleaning and outdoor purposes, while the system is also linked to requirements for rainwater infiltration and retention.
Germany uses a combination of local subsidies and economic incentives. Hamburg, for example, subsidises 40% of the investment cost of rainwater storage systems for private property owners, up to €1,500, and also allows reductions in stormwater drainage charges where rainwater is retained on the property rather than discharged into the sewer system.
For Slovenia, such a programme would be particularly interesting because it could function not only as climate policy but also as economic and industrial policy.
Subsidies could be conditional on long service life, repairability, low carbon footprints, recycled materials, local servicing capacity and smart reservoir management. This could create a domestic market for manufacturers of tanks, concrete structures, pumps, filters and sensors, as well as plumbers, construction companies and developers of digital water-management systems.
We could go a step further.
Part of each reservoir could serve as a strategic water reserve for periods of drought, while another part could remain available — or be automatically released ahead of forecast heavy rainfall — to create additional capacity for stormwater retention. The same public subsidy could therefore reduce drinking-water consumption, relieve pressure on sewerage systems and wastewater treatment plants, reduce peak flood runoff, improve household resilience during droughts and stimulate domestic economic activity.
The question, then, is no longer simply whether Slovenia can afford to subsidise water storage systems. It is also how much it will cost us if we continue to treat billions of litres of rainwater every year as waste that must be drained away as quickly as possible, rather than as a strategic resource that should be retained.
Water is not merely a raw material
A sentence has circulated for decades: that the shimmering water in streams and rivers is not just water but "the blood of our ancestors".
It is often attributed to Chief Seattle. Historically that attribution is almost certainly wrong; the famous ecological version of the speech was written for the 1972 film Home by the screenwriter Ted Perry.
Yet even with the wrong signature, the sentence lands on the right question.
Water is not an ordinary industrial input.
It is an intergenerational system.
The water we pump from an aquifer today may have taken decades to seep into it.
A glacier lost today is a reservoir from which future generations will no longer draw their summer water.
So a constitutional right determines who must have priority.
The ownership and management regime determines who decides and who pays.
But only water that has been retained, and is clean enough, determines whether there will be anything to share at all.
The water we will be paying the most to find a decade from now may be the very water we are flushing into the sewer and down the river to the sea today.
Two further texts in this series follow: on who water actually belongs to, and on the water budget of data centres.
Water Crisis vs bankruptcy
This text uses the phrase "water crisis" throughout, while its title says bankruptcy.
The distinction is deliberate.
In a paper published in Water Resources Management in January 2026 — the paper that laid the theoretical groundwork for the UNU-INWEH report — Kaveh Madani sets out three states of a human–water system: water stress, where demand is high relative to supply but the situation remains largely reversible; water crisis, an acute, shock-driven episode that temporarily exceeds capacity; and water bankruptcy, a persistent post-crisis condition defined by two things at once — withdrawals that exceed renewable inflows and the safe limits of depletion, and damage to natural capital that cannot be undone on any timescale that matters to a society.
That second condition is what separates water bankruptcy from the financial kind: an insolvent company can recover, whereas a drained aquifer, a subsided plain or a lost glacier cannot return to its baseline.
By that typology, Europe as a whole was not bankrupt in July 2026.
Low water on the Rhine and the Danube is a crisis: acute, shock-driven, and in principle reversible. But individual components of the European system already meet both conditions — the Alpine glacial reservoir most visibly, and a number of over-abstracted aquifers far less visibly.
Madani adds one point worth holding on to in a country as rain-rich as Slovenia: bankruptcy does not depend on how much water a system had to begin with, but on how it has been managed.
Crisis is what we can see.
Bankruptcy is what has been happening underneath it.
