The principle of uniformity has governed agriculture for a large portion of modern history. Regardless of minute variations in soil quality, moisture content, or plant health, large fields were handled as single, undifferentiated units that were planted, watered, fertilized, and sprayed in identical proportion. This input-heavy strategy, which was intended for simplicity and scale, increased yields at a high cost: increased greenhouse gas emissions, soil exhaustion, water waste, chemical runoff, and biodiversity loss. Even as profits per input started to level out, agriculture’s environmental impact increased as it spread into more marginal territories. This homogeneous paradigm has reached its limits in the context of a warming globe.
