History of Agriculture – Study Notes
| Period | Approx. Dates (global) | Main Characteristics | Representative Regions |
|---|---|---|---|
| Pre‑Agricultural / Foraging | ≤ 10 000 BCE | Nomadic hunting‑gathering; low population density | Worldwide |
| Neolithic Revolution | 10 000–6 000 BCE | First systematic cultivation & animal domestication; emergence of villages | Fertile Crescent (Mesopotamia), Levant, Anatolia, Nile Valley |
| Early River‑Valley Civilizations | 6 000–3 000 BCE | Irrigation, plow, grain surpluses; state formation | Mesopotamia, Egypt, Indus, Yellow River (China) |
| Bronze Age Agriculture | 3 000–1 200 BCE | Metal tools, expanded trade, crop diversification | Mediterranean, Near East, Central Asia |
| Classical & Imperial Agronomy | 1 200 BCE–500 CE | Large‑scale estates, tax‑based farming, spread of crops via empire | Greece, Rome, Maurya, Han China |
| Medieval Agrarian Systems | 500–1500 CE | Feudal manors, three‑field rotation, rise of market towns | Europe, Islamic world, Song China |
| Columbian Exchange | 1492 onward | Transfer of crops, livestock, pathogens between Old & New Worlds | Global (Atlantic world) |
| Industrial Agriculture | 18th–20th C | Mechanization, synthetic fertilizers, hybrid seeds, agribusiness | Europe, North America, later worldwide |
| Green Revolution | 1940s–1970s | High‑yield varieties, irrigation, pesticides → dramatic yield rise | Asia (India, Pakistan, Mexico), Latin America |
| Sustainable & Precision Agriculture | 1990s–present | GPS, sensors, biotech, agro‑ecology, climate‑smart practices | Global |
| Innovation | Approx. Origin | What It Changed |
|---|---|---|
| Domestication of Plants | 10 000 BCE (wheat, barley, rice, maize) | Reliable food source; selection for larger seeds, non‑shattering |
| Domestication of Animals | 9 000 BCE (goat, sheep, cattle, pig) | Meat, milk, labor, manure for fertilizer |
| Irrigation (Canals, Shadufs) | 6 000 BCE (Mesopotamia, Egypt) | Cultivation in arid zones; larger, predictable yields |
| Plow (scratch & later heavy plow) | 4 000 BCE (Mesopotamia) → 1 000 BCE (Northern Europe) | Soil turnover, deeper root growth, expansion into heavy soils |
| Crop Rotation & Fallow | 2 000 BCE (Roman “triennial” system) | Soil fertility maintenance, reduced pest buildup |
| Metal Tools (bronze, iron) | 3 000 BCE (Bronze) → 1 200 BCE (Iron) | Faster land preparation, larger fields |
