History of agriculture
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.
Agriculture in Scotland
Agriculture in Scotland includes all land use for arable, horticultural, pastoral or hunting activity in Scotland, or around its coasts. The first permanent settlements and farming date from the Neolithic period, from around 6,000 years ago. From the beginning of the Bronze Age, about 2000 BCE, arable land spread at the expense of forest. From the Iron Age, beginning in the seventh century BCE, there was use of cultivation ridges and terraces. During the period of Roman occupation there was a reduction in agriculture and the early Middle Ages were a period of climate deterioration resulting in more unproductive land. Most farms had to produce a self-sufficient diet, supplemented by hunter-gathering. More oats and barley were grown than corn, and cattle were the most important domesticated animal. From c. 1150 to 1300, the Medieval Warm Period allowed cultivation at greater heights and made land more productive. The system of infield and outfield agriculture may have been introduced with feudalism from the twelfth century. The rural economy boomed in the thirteenth century, but by the 1360s there was a severe falling off in incomes to be followed by a slow recovery in the fifteenth century.
