When an aquifer is being depleted, the technical prescription can sound straightforward: pump less.

But what happens when thousands of farmers have built their livelihoods around that pumping? When land values, debts, crops and equipment all assume continued access to water? When electricity for pumping is subsidized, agricultural policy encourages production, and governments have spent decades supporting the very system they now want to shrink?

Then “pump less” is no longer simply a water management decision.

It becomes a political and economic restructuring problem.

This is why the Global Water Bankruptcy report calls for careful attention to the political economy of water bankruptcy . Political economy asks how interests, incentives, institutions and power shape who gets water, who benefits from its use, who can resist change and who ultimately bears the costs. These questions become particularly important once a water system begins living beyond its means. Water bankruptcy describes a condition in which a human-water system persistently lives beyond its renewable water means (insolvency) while suffering effectively irreversible damage (irreversibility). But diagnosing water bankruptcy is only part of the challenge. The harder question is why societies continue unsustainable practices even when the problem is well understood and many of the solutions are already known .

The answer is that water overspending creates benefits before it creates losses . And those benefits and losses are rarely distributed evenly.

Someone benefits from water overspending

Unsustainable water use is rarely pointless.

More irrigation can mean more agricultural production, rural income, exports and jobs. More groundwater pumping can keep farms alive and farmers employed during drought. More urban water can support housing and economic growth. Cheap water can lower production costs for industry and data centers.

That is precisely why reform becomes difficult even when the problem is obvious.

When we say that a basin or aquifer is “overused,” we often describe the problem as though society as a whole were making one bad decision. In reality, water use is distributed among groups with different interests, levels of influence and dependence on the resource.

Some benefit more than others from continued overspending.

And the people who benefit today may not be the same people who bear the costs tomorrow.

Farmers are often caught inside the system

Agriculture accounts for roughly 70% of global freshwater withdrawals and represents a large share of water use in many water-stressed regions. But simply telling farmers to use less water misses the political economy of the problem .

Farmers have invested in wells, pumps, irrigation systems, orchards or greenhouses because public policy has often encouraged those investments. Land has been purchased and businesses and livelihoods have been built based on expectations about future access to water. Loans have been taken on the assumption that water would remain available. Crop choices have been shaped by subsidies, guaranteed prices, export incentives and market demand.

By the time a government decides that water use must be reduced, farmers are deeply locked into a system created not only by individual choices but also by decades of policy.

Farmers are an important part of the water problem , but they are not the architects of the system that produced it.

That distinction matters.

If authorities suddenly impose pumping limits, remove subsidies or raise water prices, the hydrological logic may be sound while the social and political consequences are severe. Farmers may lose income, land values may fall, investments may become stranded and rural communities may face economic decline. For them, water is the backbone of their livelihoods and a pillar of household economic stability.

Resistance under those circumstances should not surprise us, especially when alternative livelihoods are unavailable.

The political incentives often favor delay

Water bankruptcy also develops because the political incentives surrounding water use are asymmetric .

The benefits of overspending are often immediate and visible.

More pumping supports production. More water allocation supports development. Cheap water keeps users satisfied.

The costs may arrive years later through depleted aquifers, degraded ecosystems, declining water quality, land subsidence and irreversible ecosystem damage.

In other words, the benefits of overspending can be collected today while the bill arrives much later.

That matters politically.

Once reform becomes unavoidable, the asymmetry reverses. The benefits of restoring a water-bankrupt system are often broad and long term, while the costs of reform are immediate and concentrated.

That is a difficult political bargain , especially in democratic systems where elected officials often operate within short electoral horizons.

The environment has no lobbyist

This is one of the most important political economy problems in water management .

The beneficiaries of restoring an aquifer or a dried wetland may include millions of people, local and downstream communities, future generations and ecosystems. Yet their gains are dispersed and may take years to materialize.

Those who stand to lose water allocations, subsidies, income or asset value from reform know exactly what they are losing. They can organize. They can lobby. They can protest. Future generations cannot. The depleted aquifer and dried wetland cannot.

This imbalance helps explain why societies can recognize an unsustainable trajectory for years and still struggle to change it.

Water use becomes embedded in economic value

Long-standing water use eventually becomes more than an allocation. It becomes an economic expectation .

Farms, businesses, property values, loans and communities can all become structured around continued access to water. Companies and industries that profit from the existing model, including those selling pumps, constructing dams or promoting additional technology and infrastructure as the primary response to water shortages, may also have incentives to preserve elements of the status quo .

What may appear to a hydrologist as an unsustainable allocation can appear to a farmer or business owner as an acquired right around which a lifetime of investment has been built.

Changing those expectations can alter wealth, create winners and losers, and generate demands for compensation.

This is one reason reform becomes more difficult the longer it is delayed .

Pricing alone will not solve the political problem

Better pricing, metering, accounting and the removal of harmful subsidies are among the classic prescriptions for addressing water overuse. They all matter and can help.

But political economy asks what happens when those reforms are introduced .

A large agribusiness and a small family farmer do not have the same ability to absorb higher costs . A wealthy city and a poor rural community do not have the same capacity to adapt. A sector that benefited for decades from preferential access is not in the same position as a community that has historically had very little water security.

So the real question is not only, “What should water cost?”

Who has benefited from cheap or overallocated water?

Who has the capacity to adjust?

Who should bear the cost of restoring balance?

And who should be protected during the transition?

Technology cannot answer political questions

Engineering remains essential. Desalination, wastewater reuse, leakage reduction, irrigation efficiency, storage and other technologies can all improve water security.

But technology cannot decide how the additional water is allocated .

It cannot decide whether efficiency gains reduce pressure on an insolvent water system or simply enable more production . It cannot decide whether new supply should support households, agriculture, industry, urban growth or AI infrastructure .

Technology can change the size of the water budget. It does not decide how that budget is shared, who benefits and who bears the costs. Those are political and economic choices.

Managing water bankruptcy means managing the transition

If water bankruptcy is also a political economy problem , managing it requires more than hydrological limits and engineering projects. It requires making reform politically and socially possible.

For agriculture, that may mean helping farmers change crops, retire water rights, diversify incomes, restructure debt or develop alternative livelihoods. It may require compensation in some cases, but compensation should enable a just transition rather than subsidize continued bankruptcy.

It also requires social protection , rural investment, transparent water accounting and clear rules about who must reduce consumption and by how much. And it requires acknowledging that some activities may no longer be viable in their current form.

A just transition does not mean preserving every existing water use forever. It means managing unavoidable change fairly.

Who benefits, who loses and who pays

This is ultimately the political economy of water bankruptcy .

Who benefits from the water system as it currently operates?

Who loses when that system is transformed?

Who pays for the transition?

And who has enough political power to influence those answers?

These questions are not secondary to water management. They are central to whether reform succeeds at all.

The great challenge of water bankruptcy is therefore not simply identifying how much water must be saved. It is deciding how to change a system in which unsustainable water use has become embedded in livelihoods, asset values, subsidies, institutions and expectations.

That is why solving water bankruptcy is so politically difficult, even when many of the solutions are already known . The hydrological balance sheet tells us that change is necessary. The political economy determines whether that change is possible.
