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.
History of Africa
In the steppes and savannahs of the Sahara and Sahel in Northern West Africa, the Nilo-Saharan speakers and Mandé peoples started to collect and domesticate wild millet, African rice and sorghum between 8000 and 6000 BC. Later, gourds, watermelons, castor beans, and cotton were also collected and domesticated. The people started capturing wild cattle and holding them in circular thorn hedges, resulting in domestication. They also started making pottery and built stone settlements (see Tichitt and Oualata). Fishing, using bone-tipped harpoons, became a major activity in the numerous streams and lakes formed from the increased rains. Mande peoples have been credited with the independent development of agriculture about 3000–4000 BC.
