What Modernization Left Out

Agriculture has never produced so much data. Sensors, satellites, management consoles, declarations: every plot of land in France now generates more information in a year than all the notebooks of a generation of farmers once held.

And we have never known so little about what is on the plate. Ask anyone — a cook, a buyer, an eater — to tell the story of a product’s path from field to table: silence.

This paradox is not a wrong turn along the way. A century of agricultural modernization multiplied yields by five — and divided description by the same factor. The two movements are one and the same, and understanding why is the best way to understand what is now reversing.

The great simplification

Modernization won by simplifying. That is its method, and it has proven formidably efficient: standardize varieties, grade products, make batches equivalent, reduce the infinite variety of living things to comparable boxes. The soil — that living medium three generations could not exhaust — became three letters: N, P, K. The tomato became a size grade. The journey became a price.

And everything that did not fit in the box? It did not disappear. It fell out of the calculation. What we politely call “externalities” — water, soil that depletes or regenerates, real distances, practices, hands — are not collateral damage that happened by accident. They are the elements ejected from the description, one by one, because describing them cost money and paid nothing back.

We must be fair to this history. This movement fed cities, lifted entire rural regions out of scarcity, made food affordable to populations who had never known it that way. No one belongs in the dock. At the cost of description of the time — a man, a notebook, a distant laboratory — detaching was rational. Not everything could be counted, so what was counted was what paid. The rest was sent out back — not out of cynicism, but out of arithmetic.

What changed is not morality. It is cost.

It is often said that society has “grown aware.” That is partly true, and partly a flattering story. What has decisively changed is more prosaic: describing has become cheap.

Describing a journey once required a man and a notebook; now it takes a sensor and a data-exchange standard. Describing the state of a soil once required a laboratory and weeks of waiting; it increasingly fits into a routine measurement. Describing a change of hands once required re-entering data by hand; it can now require nothing at all, if the recording happens within the very gesture of the work.

When description was expensive, ignoring it was rational. When its cost becomes marginal, ignorance changes nature: it stops being a constraint and becomes a choice. And a choice, unlike a constraint, is visible. Yesterday’s broken chains were not a scandal — they were prohibitively expensive to maintain. Today’s are starting to look like what they have become: a decision.

Greening, or bringing back in

Faced with this shift, two responses are possible, and almost everything hinges on the difference between them.

The first is to green: add a green layer on top of the same detached process. A label on the same box. An environmental report stapled to the same calculation. One more charter in the same file. Greening has a remarkable property: it leaves the back yard exactly as it was. What had fallen out of the calculation stays out — only the door has been repainted.

The second has no everyday name, so it deserves to keep its own: to ecologize. Not adding green, but reintegrating into the calculation what had been taken out of it. Letting soil become a counted element again — not a nice-to-have. Letting the real journey weigh on the price — not just on the brochure. Letting agronomic practice enter into the value of the product — not into an appendix no one reads.

The test for telling the two apart is simple, and merciless: greening adds on; ecologizing changes the calculation. One more label has never changed a purchase price. A dependency reintegrated into the description has. Faced with any green initiative, one question is enough: is something, somewhere, now being calculated differently? If the answer is no, we have merely greened.

The second act

One misreading remains to be undone, and it is stubborn: the idea that technology stands “on the side” of detaching modernization — that agricultural digital tools merely extend the great simplification, one more box, one more dashboard.

It is exactly the opposite. The first modernization detached because it had no means to do otherwise: description was prohibitively expensive, so it simplified. Digital technology is what brought that price down. Sensors, open standards, shared registers are not the tools of a further abstraction — they are the tools of cheap description, which is to say the very instruments of reattachment.

Agritech therefore does not have to choose between productivity and description, nor stand trial for the modernization it grew out of. Its true story is more interesting than the one it is usually given: it is what finally makes compatible the two things the first act had to separate — producing at scale, and knowing what one is doing. Modernizing, second act: bringing back in what the first act had left out.

The century that has just passed divided description in order to multiply yields — it was the bargain the world could afford, and it kept its promises with the means of its time. The decade now opening can multiply description without giving up any of the yields, through exactly the same engine: falling costs. There is no going backward here, no atonement, no trial.

Modernization does not need to be undone. It has a piece left to finish.

The distinction between modernizing through detachment and ecologizing through reattachment comes from Bruno Latour, who saw in it less a quarrel between schools of thought than the central question of the century: not “should we produce?”, but “what do we count when we count?”
