Milestones

Turning points in agricultural history: famines and disasters, structural revolutions in how farming is organized, and the specific laws that reshaped land and agricultural education, including the Neolithic Revolution, the Irish Potato Famine, the British Agricultural Revolution, the Dust Bowl and the Homestead Act of 1862. The tree under this category groups by the shape of the turning point itself; a milestone driven primarily by loss is a famine or disaster, one driven by lasting structural change is a revolution or transformation, and one whose milestone is a specific act of law is a policy and legislative milestone. Does not belong here: an ongoing idea or practice that a milestone gave rise to, which is carried under Concept or Practice, or the institution a milestone created, which is carried under Institution.
