The Great Question
Can agriculture function like a natural ecosystem? 农业能否像自然生态系统一样运转？

Fifty years. One landscape. A question that changed what agriculture could mean.
The scale of the problem
What he observed
Most scientists study many places briefly. Wes Jackson studied one landscape with extraordinary patience. The Kansas prairie. He watched it through drought and rain, through political administrations and agricultural fashions. And the prairie kept doing what it had always done — sustaining itself.
No fertiliser was applied. No pesticide was sprayed. No tractor broke the surface. No irrigation pipe was laid. Yet the soil deepened. The diversity held. The system replenished.
Meanwhile, a few miles away, the Kansas farms — running on petroleum-based inputs and annual tilling — were slowly consuming themselves. Jackson noticed the contrast. He refused to look away.
"Wes Jackson did not spend fifty years trying to make nature more productive. He spent fifty years asking why nature was already productive enough."
— The question itself, as observation
What he built
The insight — the real move
Most people thought Jackson was breeding better wheat. He was actually asking: what if wheat behaved like prairie grass? What if we stopped replanting every year entirely?
Prairie grasses are perennial. They do not die each winter — they retreat, and return. Their root networks can reach two to five metres underground, tapping moisture and nutrients annual crops never touch. These roots build and hold soil across centuries. They shelter microbial communities that annual tillage destroys.
Jackson's insight was elegantly simple and radically demanding: stop trying to force nature to fit the industrial model. Instead, ask what it would mean to make agriculture more like nature.
The thinking and behaviour loop
What strikes me most, reading everything I could find about Jackson, is that his process was not linear. He did not move from problem → hypothesis → solution. He moved in a loop — one that deepened each cycle, never completing, always returning.
Observation → Question → Constraint → Build → Return to Observation
What makes this loop unusual is the role of constraint. Jackson did not try to speed up nature — he let nature set the tempo. When perennial grains took thirty years to develop commercially viable yields, he did not quit. He understood that the timeline was the point: any solution that could be built faster was probably not engaging with the real depth of the problem.
This is a lesson I find difficult. I am twenty-something, and the world is moving fast, and I want to find the answer this year. Jackson spent fifty years on one question. The patience itself is the methodology.
Navi's reflection — finding direction here
I love nature — but I have treated that love as a feeling, not a method. Jackson shows me that caring about the land is not enough. You have to stay with it, observe it, let it teach you the question it is answering. The prairie was not a metaphor for him. It was data. It was the standard.
The thing I keep returning to: he was not trying to make agriculture greener. He was trying to make agriculture more honest — honest about what a biological system can sustainably produce, honest about time horizons, honest about the gap between what we want and what the soil can actually give.
I sometimes feel like I need to have a clear direction before I can act. Jackson's life is evidence against this. He had a question — one clear, honest, impossible question — and he built an institution, a career, a lifetime around holding it open. The question was the direction.
My question, the one I am borrowing from this station until I grow my own: What would it mean to design human systems the way the prairie designs itself — with patience, with polyculture, with deep roots?
I do not have the answer. I am not supposed to. Not yet.
