When did agriculture begin?

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.

Wild grains were collected and eaten from at least 20,000 BC. From around 9500 BC, the eight Neolithic founder crops – emmer wheat, einkorn wheat, hulled barley, peas, lentils, bitter vetch, chick peas, and flax – were cultivated in the Levant. Rye may have been cultivated earlier but this remains controversial. Rice was domesticated in China by 6200 BC with earliest known cultivation from 5700 BC, followed by mung, soy and azuki beans. Pigs were domesticated in Mesopotamia around 11,000 BC, followed by sheep between 11,000 BC and 9000 BC. Cattle were domesticated from the wild aurochs in the areas of modern Turkey and Pakistan around 8500 BC. Sugarcane and some root vegetables were domesticated in New Guinea around 7000 BC. Sorghum was domesticated in the Sahel region of Africa by 5000 BC. In the Andes of South America, the potato was domesticated between 8000 BC and 5000 BC, along with beans, coca, llamas, alpacas, and guinea pigs. Bananas were cultivated and hybridized in the same period in Papua New Guinea. In Mesoamerica, wild teosinte was domesticated to maize by 4000 BC. Cotton was domesticated in Peru by 3600 BC. Camels were domesticated late, perhaps around 3000 BC.

Following the footsteps of the Enlightenment rationalism and experimentalism, Germany began to see the rise of agricultural experiment stations, indicating the beginnings of an attempt to merge traditional agronomy with analytical chemistry. In 1840, Justus von Liebig, an influential German chemist and professor at the University of Giessen, published his book "Organic Chemistry in its Application to Agriculture and Physiology". Liebig theorized that nitrogen and trace minerals from soil erosion were essential to plant nutrition, and, from this analytical chemistry perspective, simplified agriculture to a series of chemical reactions. While Liebig’s work inspired a generation of analytical agricultural chemists interested in fundamental questions of plant nutrition, founders of early German agricultural experiment stations did not solely seek to pursue questions of soil chemistry, but rather sought to bridge the gap between the two fields of agriculture and chemistry.

Since the revolution in 1949, China has devoted most of its investments and administrative energy to the industrial sector. Generally, the agricultural sector received special attention only when the leaders perceived that the sector was beginning to restrain China's overall economic development. Agricultural output basically kept pace with the growth of population but did not expand fast enough to raise living standards. Per capita consumption of grains, fibers, edible oil, sugar, fruits, vegetables, fish, meat, eggs, and dairy products remained low. The value of goods generated by the agricultural sector has grown, but not as fast as output generated by other sectors in the economy. In 1949 about half of the country's output came from the agricultural sector. This ratio dropped to 41 percent by 1955, declined to 31 percent by 1965, and fell another few percentage points in 1975 to 25 percent. But agricultural reforms initiated in the early 1980s brought a rise in agriculture to 33 percent of GDP in 1985. At the same time, more than 60 percent of the national labor force was employed in agriculture.

It was first suggested that farmers could be paid for "producing countryside" in 1969, but the real beginning of positive agri-environmental policy came with the Agriculture Act 1986. The Countryside Stewardship Scheme and local equivalents were run by the Countryside Commission and the Countryside Council for Wales from 1991 until 1996, when they came under ministry control. Nowadays schemes to encourage farmers to think about wildlife conservation and to farm in an environmentally friendly way abound, though actual payments to farmers to support this are comparatively modest.

On government instructions, the Northfield Committee began to review the country's agricultural system in 1977. It did not report until July 1979, by which time Margaret Thatcher's administration held power. The report influenced ongoing discussions between the NFU and the Country Landowners Association (CLA), who were trying to reach an agreement on new Agricultural Holdings legislation that could be presented to Parliament as having industry-wide support. This was agreed in 1984, but the two sides had not been able to agree a fundamental change to the security of tenure legislation. It did change the succession rules for existing tenancies such that a farmer might pass on his tenancy on retirement as well as on death—but no new tenancies from 1984 were to include succession rights.

Settlement of the area dates to the 1830s when Tarneit was used as agricultural grazing land. Tarneit was named when it was surveyed in 1839–1840 and comes from the Wathaurong word for the colour white. The road network was largely planned in a square mile grid pattern and still forms the basis of the arterial road network today. Large scale residential subdivision did not begin until the 1990's.

"We designed the building from the inside out, not the outside in,” said Loretta H. Cockrum, Foram’s founder, chairman and CEO. “We wanted the most efficient office building ever designed, with no wasted space or wasted energy. This is a building of the future more than a building of the present. A lot of love has gone into that building, and a lot of pride."

This enzyme belongs to the family of oxidoreductases, specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen. The oxygen incorporated need not be derived from O2 with 2-oxoglutarate as one donor, and incorporation of one atom o oxygen into each donor. The systematic name of this enzyme class is N6,N6,N6-trimethyl-L-lysine,2-oxoglutarate:oxygen oxidoreductase (3-hydroxylating). Other names in common use include trimethyllysine alpha-ketoglutarate dioxygenase, TML-alpha-ketoglutarate dioxygenase, TML hydroxylase, 6-N,6-N,6-N-trimethyl-L-lysine,2-oxoglutarate:oxygen oxidoreductase, and (3-hydroxylating). This enzyme participates in lysine degradation and L-carnitine biosynthesis and requires the presence of iron and ascorbate.

Ŭ represents a semivowel in the orthography of Esperanto, which is an international auxiliary language publicly presented in 1887. As in Belarusian, Esperanto Ŭ is pronounced as a non-syllabic , primarily in the diphthongs "aŭ", "eŭ" and rarely "oŭ".

Ɯ was used in the Zhuang alphabet from 1957 to 1986 to represent the same vowel as in IPA; sometime before or in 1986, it was replaced with W.
