Atlas Trail
Eight stops through this wave's own research: the science of grazing land, the ancient practice of moving herds by season, an insect bred entirely out of the wild for its thread, two reactions against industrial farming, and the ground itself, its erosion, its worst-case desert future, and the chemistry that feeds it back.
Stop 1 of 8.
Disciplines
How much a pasture can support before it stops recovering: a twentieth-century discipline built out of overgrazing and Dust Bowl-era crises.
Stop 2 of 8.
Practices
Range science's oldest working method: moving herds between fixed seasonal pastures, practiced since before written record.
Stop 3 of 8.
Disciplines
A different kind of husbandry entirely: silkworms bred so completely for their thread that the species no longer exists in the wild, its own origin a genuinely open question.
Stop 4 of 8.
Practices
From 1940. The named reaction against synthetic fertilizer and pesticide, running back through Albert Howard's work in India to Rudolf Steiner's 1924 lectures.
Stop 5 of 8.
Practices
1978. Bill Mollison and David Holmgren's answer taken further: design the farm to behave like the ecosystem it replaced.
Stop 6 of 8.
Concepts
What every practice above is ultimately managing against: topsoil lost ten to forty times faster than it naturally forms.
Stop 7 of 8.
Concepts
Erosion's worst outcome, and a live scientific argument: is the Sahel's decline mainly climate cycle or human pressure? The record supports both readings.
Stop 8 of 8.
Concepts
The trail ends where fertility gets rebuilt, biologically by rhizobia in a legume's roots or industrially at 200 atmospheres, feeding a population that grew from two billion to over eight.
