Green Revolution—a triumph of science and technology, still returned to as a touchstone since the 1960s. A revolution that doubled cereal yields from one ton per hectare to two tons per hectare over two decades. It later spread widely across the places where we work. This we know.
Yet after that initial doubling, yields stay low and far below science's potential in most places, even as science and technology continue to advance. New varieties appear. New techniques accumulate. Knowledge does not stop. Where yields rise, they do so with subsidized inputs, support prices, or in tandem with economy-wide income growth. Yields settle where production can continue, but far below science's potential. This is in the record.
In Transforming Traditional Agriculture, T. W. Schultz showed in 1964 that farmers are rational economic agents who respond to profitable incentives. Economics and other research since has recorded farmers increasing science and technology adoption to raise yields only when the potential to earn is visible—and stepping back from technologies that yield little return and stepping up when returns are high, even if only briefly. All of this is in the record, yet it has not informed how Development works. This we Question.
And there has been a quiet revolution since the Green Revolution, starting again from about one ton per hectare, but rising to ten within two decades. It reached science's yield potential in that span of time, and it remained outside Development's view.
For decades, farmers in Bangladesh grew little maize, a minor crop compared to rice and wheat, at yields less than one ton per hectare. Green Revolution technologies and those developed since were available for maize as for other cereals. But they mostly stayed unadopted. This is in the record.
Then, beginning in 2000, maize yields began to rise. Over the next two decades, yields surged to maize's yield potential of about ten tons per hectare. The cropland grown to maize expanded sharply at the same time, increasing well over 100-fold its 2000 base, making maize the second largest cereal crop in Bangladesh, surpassing wheat. Achieving those yields across that land required high use of technology and inputs, which flowed readily to farmers. Science's potential was met by farmers who chose to grow maize. All of this is in the record.
Income from maize stays in sight for farmers in Bangladesh as maize demand still outstrips supply. Bangladesh still imports maize. That scarcity cannot be reproduced—it arose in the market and holds only as long as the market holds it. But while it holds, income stays visible and the revolution continues. This quiet maize revolution has stayed out of sight for Development. This is in the record.
A quiet revolution not because science changed or the economy shifted from narrow-based to broad-based, but because rising demand for poultry, fish, and dairy products drove demand for maize as feed, and income from maize became visible within the narrow, with no development project in sight. This is in the record.
What it brings into view is how income potential releases farmer agency, and how that agency produces access to the science, the inputs, and the learning needed to reach it. Farmer agency does the rest—farmers seeking what they need once that potential becomes visible, and providers meeting them because the potential to earn is visible to them as well. What economics and farmers have always affirmed, and what the record shows, is that the potential to earn is what releases that agency. This we Question.
The farmers who drove that revolution had none of what the Questions put in the frame. No scaling coalition reached them. No pilot was designed for them. No new advisory guided their shift. No study of their behavior made them shift. No inclusion program brought them in. No special input or credit scheme targeted them. No new innovation, transformation, or systems concept shaped their choice. No firm or value chain was built for them. No social return on investment was recorded for them. This we Question.
When income from maize became visible and high, subsistence farmers shifted to maize and those who had left farming returned—toward what science had long made possible. Buyers saw the potential to earn in maize, farmers saw the potential to earn in growing it, and providers saw the potential to earn in supplying what farmers now needed, and science’s potential was reached. And yet that drive—farmers reaching for science’s potential—remains quiet, not because the evidence is unclear, but because it stays outside what the Questions keep in view. This we Question.
What was there was the science and technology accumulated over decades by domestic and international research. The maize revolution reached far closer to science's potential than the Green Revolution did, a greater triumph of science, letting us see how income always moves yields toward that ceiling, however it arrives. Income became visible, and farmers moved toward science's potential, on their own terms, to a scale no program produced. But the revolution can stay only while income does—just as the Green Revolution did for about two decades. This we Question.
In Bangladesh, rice, wheat, and other crops remain in view. Long supported and promoted through the Questions, their yields increase slowly and remain far below science’s potential. This is in the record.
Elsewhere, maize yields are stagnant for decades. Across Africa, maize yields sit at or below 2 tons per hectare, less than even a fourth of science’s potential there. Kenya’s highest recorded yield of 2.1 tons per hectare was reached in 1982. This is in the record.
The same science. The same technologies. Farmers respond to income. They always have. Yet what stays in view for smallholder escape from poverty, through the Questions, remains new technology, reduced toil, and food security. This we see.
The quiet maize revolution in Bangladesh and the quiet maize stagnation elsewhere arise from the same source: farmer agency, skill, and effort—deployed when income is visible, and held back when it is not. This we Question.
So here is the Unquestion:
If the potential to earn releases farmer agency and unlocks a science-aligned maize revolution in Bangladesh, what does it tell us about what the Questions have kept in view?
And if buyers, farmers, and providers engage in the markets when the potential to earn becomes visible for all, what does it tell us comes before access to inputs and science?
If this Unquestion meets one you have carried quietly, this is the place to say it out loud, so we can see the clarity we already hold together.
The more we Unquestion, the more clarity we gain. The more we Unquestion now, the less future generations will have to.
We are not lost.
We simply avoid the turn.
Once we Unquestion, the direction is already clear.
Thank you for seeing.
