Definition
Agriculture is the deliberate cultivation of plants and the raising of animals for food, fiber, and other resources. It emerged independently in several regions of the world beginning roughly twelve thousand years ago, replacing a way of life based entirely on hunting and gathering.
The shift to farming, often called the Neolithic Revolution, did not happen overnight. Communities gradually domesticated wild grains, legumes, and animals, selecting for traits such as larger seeds and tamer behavior, until settled cultivation became the dominant means of survival.
Why it matters
How it works
A farming society concentrates labor on a small number of high-yield crops and domesticated animals near a reliable water source. Surplus grain can be stored against lean seasons and traded for goods that the community cannot produce itself. That surplus is what supports specialists who do no farming at all — and the institutions, armies, and monuments those specialists build. The trade-off is dependence: a settled, dense population cannot easily move when soil exhausts, rivers shift, or harvests fail.
