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. The early modern era saw the impact of the Little Ice Age, which peaked towards the end of the seventeenth century. The closing decade of the seventeenth century saw a slump, followed by four years of failed harvests, in what is known as the "seven ill years", but these shortages would be the last of their kind. After the Union of 1707 there was a conscious attempt to improve agriculture among the gentry and nobility. Introductions included haymaking, the English plough, new crops, crop rotation and encloses were introduced. The resulting Lowland Clearances saw hundreds of thousands of cottars and tenant farmers from central and southern Scotland forcibly removed. The later Highland Clearances saw the forced displacement much of the population of the Highland as lands were enclosed for sheep farming. Those that remained many were now crofters, living on very small rented farms. In the twentieth century Scottish agriculture became susceptible to world markets. There were dramatic price rises in the First World War, but a slump in the 1920s and 1930s, followed by more rises in World War II. In 1947 annual price reviews were introduced in an attempt to stabilise the market. There was a drive in UK agriculture to greater production until the late 1970s, resulting in intensive farming. There was increasing mechanisation and farming became less labour-intensive. UK membership of the European Economic Community from 1972 began a change in orientation for Scottish farming. Some sectors became viable only with subsidies. A series of reforms to the CAP from the 1990s attempted to control over-production, limit incentives for intensive farming and mitigate environmental damage. A dual farm structure has emerged with agriculture divided between large commercial farms and small pluralised and diversified holdings. Roughly 79 per cent of Scotland’s total land area is under agricultural production. Cereals accounted for 78 per cent of the land area,, while livestock numbers have been falling in recent years. Around 15 per cent of the total land area of Scotland is forested, most in public ownership controlled by the Forestry Commission. Total income from farming has been rising since the turn of the millennium. Aquaculture production is focused on the West and North of the country. Some farm businesses rely on sources of income other than from farming. Scottish agriculture employs around 1.5 per cent of the workforce and contributes to around 1 per cent of the Scottish economy. ==Topography and climate== The defining factor in the geography of Scotland is the distinction between the Highlands and Islands in the north and west and the Lowlands in the south and east. The Highlands are further divided into the Northwest Highlands and the Grampian Mountains by the fault line of the Great Glen. The Lowlands are divided into the fertile belt of the Central Lowlands and the higher terrain of the Southern Uplands, which included the Cheviot hills, over which the border with England runs.〔R. Mitchison, ''A History of Scotland'' (London: Routledge, 3rd edn., 2002), ISBN 0415278805, p. 2.〕 The Central Lowland belt averages about 50 miles in width,〔''World and Its Peoples'' (London: Marshall Cavendish), ISBN 0761478833, p. 13.〕 and contains most of the good quality agricultural land.〔J. Wormald, ''Court, Kirk, and Community: Scotland, 1470–1625'' (Edinburgh: Edinburgh University Press, 1991), ISBN 0748602763, pp. 39–40.〕 Scotland is half the size of England and Wales in area, but with its many inlets, islands and inland lochs, it has roughly the same amount of coastline at 4,000 miles. Only a fifth of Scotland is less than 60 metres above sea level.〔C. Harvie, ''Scotland: a Short History'' (Oxford: Oxford University Press, 2002), ISBN 0192100548, pp. 10–11.〕 Scotland's soils are diverse for a relatively small country due to the variation in geology, topography, climate, altitude and land use history. There are very productive arable soils in the east of the country, including some of the most productive for wheat and barley of anywhere in the world. Scotland's soils differ from much of the rest of the UK and Europe and they provide valuable habitats for wildlife and flora. They are largely naturally acidic in nature with high concentrations of organic carbon. They are predominantly coarse textured and often exhibit poor drainage.〔(Scotland's soils: key facts ), Scotland's Environment, retrieved 1 June 2015.〕 The climate of Scotland is temperate and very changeable, but rarely extreme.〔(Met Office: Scottish climate ), Met Office, retrieved 1 June 2015.〕 Scotland is warmed by the North Atlantic Drift and given the northerly location of the country, experiences much milder conditions than areas on similar latitudes. Average temperatures are lower than in the rest of Great Britain. Western coastal areas of Scotland are warmer than the east and inland areas, due to the influence of the Atlantic currents, and the colder surface temperatures of the North Sea.〔(Mean Temperatures Annual Average ), Met Office, retrieved 1 June 2015.〕 Rainfall totals vary widely across Scotland—the western highlands of Scotland are one of the wettest places in the UK with annual rainfall up to . In comparison, much of eastern Scotland receives less than annually; lying in the rain shadow of the western uplands.〔(Rainfall Amount Annual Average ) Met Office, retrieved 1 June 2015.〕 Annual average sunshine totals vary from as little as 711–1140 hours in the Highlands and the north-west up to 1471–1540 hours on the extreme eastern and south-western coasts.〔(Sunshine Duration Annual Average ), Met Office, retrieved 1 June 2015.〕 Wind prevails from the south-west, bringing warm, wet and unstable air from the Atlantic.〔 The windiest areas of Scotland are in the north and west, with parts of the Outer Hebrides, Orkney and Shetland experiencing over 30 days with gales per year.〔 Vigorous Atlantic depressions, also known as European windstorms, are a common feature of the autumn and winter in Scotland.〔(Lichens – The Exceptional Scottish climate ), Scottish National Heritage (SNH), retrieved 1 June 2015.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Agriculture in Scotland」の詳細全文を読む スポンサード リンク
