Agrarian society
Agrarian society were preceded by hunter and gatherer and horticultural societies and transition into industrial society. The transition to agriculture, called the Neolithic Revolution, has taken place independently multiple times. Horticulture and agriculture as types of subsistence developed among humans somewhere between 10,000 and 8,000 years ago in the Fertile Crescent region of the Middle East. The reasons for the development of agriculture are debated but may have included climate change, and the accumulation of food surplus for competitive gift-giving. Most certainly there was a gradual transition from hunter-gatherer to agricultural economies after a lengthy period when some crops were deliberately planted and other foods were gathered from the wild. In addition to the emergence of farming in the Fertile Crescent, agriculture appeared in: by at least 6,800 B.C.E. in East Asia (rice) and, later, in Central and South America (maize and squash). Small-scale agriculture also likely arose independently in early Neolithic contexts in India (rice) and Southeast Asia (taro). However, full dependency on domestic crops and animals, when wild resources contributed a nutritionally insignificant component to the diet, did not occur until the Bronze Age.
Natufian culture
According to one theory, it was a sudden change in climate, the Younger Dryas event (c. 10,800 to 9500 BC), that inspired the development of agriculture. The Younger Dryas was a 1,000-year-long interruption in the higher temperatures prevailing since the Last Glacial Maximum, which produced a sudden drought in the Levant. This would have endangered the wild cereals, which could no longer compete with dryland scrub, but upon which the population had become dependent to sustain a relatively large sedentary population. By artificially clearing scrub and planting seeds obtained from elsewhere, they began to practice agriculture. However, this theory of the origin of agriculture is controversial in the scientific community.
