The grain trade refers the local and international trade in cereals and other food grains such as wheat, maize, and rice. ==History== The grain trade is probably nearly as old as grain growing, going back the Neolithic Revolution ( around 9,000 BC ). Wherever there is a scarcity of land (e.g. cities) people must bring in food from outside to sustain themselves, either by force or by trade. However, many farmers throughout history (and today) have operated at the subsistence level, meaning they produce for household needs and have little leftover to trade. The goal for such farmers in not to specialize in one crop and grow a surplus of it, but rather to produce everything his family needs and become self-sufficient. Only in places and eras where production is geared towards producing a surplus for trade (commercial agriculture), does a major grain trade become possible. Early trade was most likely by barter, and because hauling large amounts of grain around was so difficult with ancient technology, the trade was probably quite limited in terms of the volume traded and the area moved. The development of the money economy and the wheel would have facilitated a much more expansive trade. In the ancient world, grain regularly flowed from the hinterlands to the cores of great empires: maize in ancient Mexico, rice in ancient China, and wheat and barley in the ancient Near East. With this came improving technologies for storing and transporting grains; the Hebrew Bible makes frequent mention to ancient Egypt's massive grain silos. During the classical age, the unification of China and the pacification of the Mediterranean basin by the Roman Empire created vast regional markets in commodities at either end of Eurasia. The grain supply to the city of Rome was considered by be of the utmost strategic importance to Roman generals and politicians. In Europe with the collapse of the Roman system and the rise of feudalism many farmers were reduced to a subsistence level, producing only enough to fulfill their obligation to their lord and the Church, with little for themselves, and even less for trade. The little that was traded was moved around locally at regular fairs. A massive expansion in the grain trade occurred when Europeans were able to bring millions of square kilometers of new land under cultivation in the Americas, Russia, and Australia, in an expansion starting in the fifteenth and lasting into the twentieth century. In addition the consolidation of farmland in Britain and Eastern Europe, and the development of the railway and steam ship shifted trade from local to more international patterns. During this time debate over tariffs and free trade in grain was fierce. Poor industrial workers relied on cheap bread for sustenance, but farmers wanted their government to create a higher local price to protect them from cheap foreign imports, Britain's famous Corn Laws being an example. As Britain and other European countries industrialized and urbanized they became net importers of grain from the various breadbaskets of the world. In many parts of Europe as serfdom was abolished, great estates were accompanied by many inefficient smallholdings, but in the newly colonized regions massive operations were available to the average farmer and not only great nobles. In the United States and Canada the Homestead Act and the Dominion Lands Act allowed pioneers on the western plains to gain tracts of or more for little or no fee. This moved grain growing, and hence trading, to a much more massive scale. Huge grain elevators were built to take in farmers' produce and move it out via the railways to port. Transportation costs were are major concern for farmers in remote regions, however, and any technology that allowed the easier movement of grain was of great assistance, meanwhile farmers in Europe struggled to remain competitive while operating on a much smaller scale and in 1911 Encyclopædia Britannica wrote: The farmers of the United States have met a greatly increased output from Canada, the cost of transport from that country to England being much the same as from the United States in the 20th century. So much improved is the position of the farmer in North America compared with what it was about 1870, that the transport companies in 1901 carried 17¾ bushels of his grain to the seaboard in exchange for the value of one bushel, whereas in 1867 he had to give up one bushel in every six in return for the service. In the 1920s and '30s farmers in Australia and Canada reacted against the pricing power of the large grain-handling and shipping companies. Their governments created the Australian Wheat Board and Canadian Wheat Board as monopsony marketing boards, buying all the wheat in those countries for export. Together those two boards controlled a large percentage of the world's grain trade in the mid-20th century. Additionally, farmers' cooperatives such the wheat pools became a popular alternative to the major grain companies. At the same time in the Soviet Union and soon after in China, disastrous collectivization programs effectively turned the world's largest farming nations into net importers of grain. By the second half of the 20th century, the grain trade was divided between a few state-owned and privately owned giants. The state giants were Exportkhleb of the Soviet Union, the Canadian Wheat Board, the Australian Wheat Board, the Australian Barley Board, and so on. The largest private companies, known as the "big five", were Cargill, Continental, Louis Dreyfus, Bunge, and Andre, an older European company not to be confused with the more recent André Maggi Group from Brazil. In 1972, the Soviet Union's wheat crop failed. To prevent shortages in their own country, Soviet authorities were able to buy most of the surplus American harvest through private companies without the knowledge of the United States government. This drove up prices across the world, and was dubbed the "great grain robbery" by critics, leading to greater public attention being paid by Americans to the large trading companies. 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「Grain trade」の詳細全文を読む スポンサード リンク
