The New General Water Law and the Hidden Cost of Food

For decades, agricultural water was treated as an implicit input, almost invisible. It was taken for granted that it was there, that it was sufficient, and that its cost could be diluted within the production cycle, but that logic has now broken down. The discussion around the new General Water Law marks a turning point: water has ceased to be a technical issue and has become a first-order economic, political, and social matter.

The debate is not minor. Mexico faces growing water stress, overexploited aquifers, and an obsolete irrigation infrastructure. Bringing order to water use is necessary. The problem lies in how, to whom, and at what speed the adjustment is expected to be charged. And that is where the countryside raised its voice.

Water Is No Longer Sufficient

The new General Water Law is based on an undeniable reality. Water is poorly distributed, poorly measured, and in many cases poorly used. Old concessions, duplicated titles, irregular use, and weak oversight have created an unsustainable water system. In that sense, the intention to organize, measure, and charge for the real use of the resource makes sense.

It is also reasonable to prioritize human and environmental consumption, as well as to encourage greater efficiency in intensive sectors. Agriculture uses around 70% of the country’s available freshwater. Ignoring that fact would be irresponsible.

Up to this point, the diagnosis is correct. The problem begins when the solution is built without considering the real conditions of the countryside.

However, the main concern for producers is not the principle of regulation, but the way it is intended to be implemented. Talking about strict measurement, new tariffs, possible sanctions, or concession reviews in a context where irrigation technification remains limited is a dangerous equation.

For years, the Mexican countryside has operated with open channels, gravity-based systems, and inefficient pumping, not by choice, but due to a lack of sustained public investment. Today, efficiency is being demanded without having previously provided the tools to achieve it. 

Efficiency cannot be charged where efficiency was never invested in. Doing so is equivalent to transferring the cost of historical disorder directly onto the producer.

Agricultural Irrigation as a Scapegoat

Another risk in the current narrative is turning agricultural irrigation into the automatic villain of the water problem. It is true that agriculture consumes the majority of water, but it is also true that it produces food, generates rural employment, and sustains entire regional economies.

Treating a maize, wheat, or vegetable producer the same way as a real estate developer, a mining company, or an industrial park ignores the social value of water use. The problem is not who uses more water, but who uses water without generating a proportional benefit for society.

When regulation fails to distinguish between strategic productive uses and purely extractive uses, the result is not sustainability, but expulsion.

Why Did the Countryside Take to the Streets?

Recent protests did not arise from resistance to order, but from fear of being left out of the system. For producers, water is not just another input, it is the critical input. If its cost increases without the price of food rising in the same proportion, margins disappear.

Producers understand something that is often ignored in public policy design: if water becomes more expensive without a transition, planting stops. Fear of concession cancellations, reclassification of uses, new tariffs, or administrative burdens without financial support set off alarms. For many farmers, the law does not sound like regulation; it sounds like a silent expulsion from the productive system.

And this is where we reach the most delicate point of the debate. A poor implementation of the General Water Law could have effects opposite to those intended. Less planted area, land abandonment, and a decline in national production open the door to greater dependence on imports.
This does not only affect producers. It affects consumers.

More expensive water in the countryside ultimately translates into higher food prices on the table or greater dependence on foreign supply to meet domestic demand. Protecting water is essential. But neglecting food production is a strategic mistake.

At the end of the day, the debate should not focus on whether the law is good or bad, but on how it is implemented. There are middle paths that would allow the resource to be protected without suffocating producers.

Gradual transitions, large-scale technification programs, accessible financing for efficient irrigation, and differentiated schemes that charge more to those who waste and protect those who produce basic foods. Water must be understood as food policy, not only as environmental policy.

Water is not free, but it cannot be charged as if the countryside were a luxury.

The hidden cost of this discussion is not found only in tariffs. It lies in what Mexico could lose if it fails to balance water sustainability with productive viability. The countryside does not oppose caring for water. It opposes doing so alone, without support and without a fair transition.

Bringing order to water use is necessary. Bringing order to the countryside is necessary as well.

If the new General Water Law fails to integrate both, the cost will not be paid only by farmers. We will all pay it, every time food prices rise or national production gives way to imports. Because in the end, caring for water and caring for producers are not opposing goals. They are two sides of the same food security challenge.
