Humanity has entered a new, dangerous era, which UN scientists define as global water bankruptcy. This state of affairs is not just a temporary crisis, but a systemic failure in which we have irreversibly overexploited the planet's water resources to such an extent that ecosystems and economies are in danger. they can no longer return to their original state. According to the latest news Almost three quarters of the world's population live in countries with critical water shortages, and further significant deterioration is expected by 2100 under the influence of accelerating climate change.

From water crisis to bankruptcy: A new diagnosis

The traditional language of „water crisis“ is no longer sufficient to explain the current reality. A crisis in risk management presupposes an exceptional, time-limited shock (such as a drought or flood) followed by recovery and a return to normality. Water bankruptcy however, it describes a post-crisis state in which natural water capital is permanently damaged and a return to previous levels of supply is unrealistic.

This concept uses a financial analogy: society relies on annual „income“ in the form of renewable flows (rivers, precipitation) and „savings“ stored in aquifers, glaciers, and soil. However, many regions have been drawing not only income but also the very principal of this hydrological capital for decades. When spending (consumption) exceeds income over a long period of time, the system becomes insolvent and irreversible damage occurs, such as aquifer compaction or glacier retreat.

Climate change as an accelerator of decline

Climate change is acting as a catalyst that is destabilizing the global hydrological cycle and pushing the planet beyond the safe operating space. According to the report Planetary Health Check 2025 Freshwater is one of seven of the nine planetary boundaries that have already been crossed.

The impact of warming on water is direct and devastating:

• Cycle intensification: Every 1°C of global warming increases the atmosphere's ability to hold moisture by 7 %, leading to more extreme weather events – more devastating floods on the one hand and more brutal droughts on the other.
• Anthropogenic drought: The combination of climate change and human activity (deforestation, over-pumping of groundwater) has turned occasional droughts into chronic conditions. Drought-related damages now amount to approximately $307 billion per year worldwide.
• Loss of "green water": Climate change is disrupting the water component of soil and vegetation, known as green water. Degradation of forests and wetlands reduces the land's ability to recycle moisture, which in turn reduces rainfall in other regions.

Visible faces of bankruptcy: Glaciers and groundwater

The depletion of planetary water supplies is most evident in two areas: the cryosphere and underground reservoirs. Since 1970, the world has lost more than 30 % glacier masses. These „water towers“ are critical for hundreds of millions of people in Asia and the Andes, for whom they provide a seasonal buffer for drinking water and agriculture. Their retreat means a permanent loss of water reserves that cannot be restored on a human timescale.

Equally alarming is the state of groundwater, which provides 50 % of domestic consumption and 40 % of irrigation worldwide. Approximately 70 % main aquifers is showing a decreasing trend. Excessive pumping is causing subsidence on more than 6 million km² of the Earth's surface. In some areas, the land is sinking by up to 25 cm per year, permanently destroying geological structures capable of retaining water.

Slovak context and future risks

Slovakia is not immune to these trends either. The Water Research Institute (VÚVH) warns that climate change is already changing our hydrological regime. By 2100, Slovakia is expected to decrease in usable water resources by 30 to 50 %.

The main hydrological changes in our country include:

• Increased runoff in winter and spring, but significant decrease in summer and autumn.
• Loss of snow cover and earlier melting, leading to water shortages later in the growing season.
• Deterioration of groundwater quality due to lower dilution of pollutants during drought and their increased mineralization.
• High risk of water shortage, especially in the southern regions of Slovakia.

Agriculture at the heart of the crisis

Agriculture consumes up to 70 % of all freshwater withdrawals. More than half of the world's food production is now located in areas where water supplies are unstable or declining. Climate change is increasing this pressure, with soil erosion and loss of soil moisture leading to desertification.

The solution must be a new revolution in food systems, focused on increasing water productivity and shifting to regenerative agriculture. The UN proposes reducing reliance on water-intensive foods and shifting subsidies (worth $700 billion per year) that currently support unsustainable consumption towards resource-saving innovations.

From crisis management to bankruptcy administration

Recognizing the era of water bankruptcy is not resignation, but a necessary diagnostic step. The UN report calls for a shift from reactive crisis management to bankruptcy management, which includes:

1. Admission of insolvency: Transparent accounting of how much water we actually have and how much we have already irretrievably lost.
2. Preventing further damage: Setting hard limits on activities that destroy remaining natural capital (e.g. banning further extraction in critically depleted aquifers).
3. Fair redistribution: Water bankruptcy is a question of justice and security. The costs of adjusting consumption patterns must not be borne only by the most vulnerable (small farmers, poor communities) while the benefits remain for the powerful.
4. Water as a global common good: We must manage the water cycle collectively, just as we strive to protect the climate.

Water as a bridge to stability

The upcoming UN Water Conferences in 2026 and 2028 represent a key opportunity to reset the global agenda. Water must not be seen simply as a victim of climate change, but as a strategic sector for cooperation. Investments in restoring the water cycle, wetlands and forests are also investments in climate change mitigation and peacekeeping.

If we continue to ignore the hydrological debt, future generations will pay the interest in the form of displacement, hunger, and conflict. Global water bankruptcy is a warning that the time for half-baked solutions is over. We must start living within our hydrological means while we still have some natural capital worth saving. JRi&CO2AI
