City
A city is a human settlement of notable size.Goodall, B. (1987) ''The Penguin Dictionary of Human Geography''. London: Penguin.Kuper, A. and Kuper, J., eds (1996) ''The Social Science Encyclopedia''. 2nd edition. London: Routledge. It can be defined as a permanent and densely settled place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organisations and businesses, sometimes benefiting different parties in the process, such as improving efficiency of goods and service distribution. Historically, city-dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization, more than half of the world population now lives in cities, which has had profound consequences for g ...

Ogallala Aquifer
The Ogallala Aquifer () is a shallow water table aquifer surrounded by sand, silt, clay, and gravel located beneath the Great Plains in the United States. One of the world's largest aquifers, it underlies an area of approximately in portions of eight states (South Dakota, Nebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, and Texas). It was named in 1898 by geologist N. H. Darton from its type locality near the town of Ogallala, Nebraska. The aquifer is part of the High Plains Aquifer System, and resides in the Ogallala Formation, which is the principal geologic unit underlying 80% of the High Plains. Large-scale extraction for agricultural purposes started after World War II due partially to center pivot irrigation and to the adaptation of automotive engines for groundwater wells. Today about 27% of the irrigated land in the entire United States lies over the aquifer, which yields about 30% of the ground water used for irrigation in the United States. The aquif ...

Census
A census is the procedure of systematically acquiring, recording and calculating information about the members of a given population. This term is used mostly in connection with national population and housing censuses; other common censuses include censuses of agriculture, traditional culture, business, supplies, and traffic censuses. The United Nations (UN) defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory, simultaneity and defined periodicity", and recommends that population censuses be taken at least every ten years. UN recommendations also cover census topics to be collected, official definitions, classifications and other useful information to co-ordinate international practices. The UN's Food and Agriculture Organization (FAO), in turn, defines the census of agriculture as "a statistical operation for collecting, processing and disseminating data on the structure of agriculture, covering th ...

Semi-arid Climate
A semi-arid climate, semi-desert climate, or steppe climate is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. Defining attributes of semi-arid climates A more precise definition is given by the Köppen climate classification, which treats steppe climates (''BSk'' and ''BSh'') as intermediates between desert climates (BW) and humid climates (A, C, D) in ecological characteristics and agricultural potential. Semi-arid climates tend to support short, thorny or scrubby vegetation and are usually dominated by either grasses or shrubs as it usually can't support forests. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined. The method used to find the precipitation threshold (in millimeters): *multiply by ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Humid Continental Climate
A humid continental climate is a climatic region defined by Russo-German climatologist Wladimir Köppen in 1900, typified by four distinct seasons and large seasonal temperature differences, with warm to hot (and often humid) summers and freezing cold (sometimes severely cold in the northern areas) winters. Precipitation is usually distributed throughout the year but often do have dry seasons. The definition of this climate regarding temperature is as follows: the mean temperature of the coldest month must be below or depending on the isotherm, and there must be at least four months whose mean temperatures are at or above . In addition, the location in question must not be semi-arid or arid. The cooler ''Dfb'', ''Dwb'', and ''Dsb'' subtypes are also known as hemiboreal climates. Humid continental climates are generally found between latitudes 30° N and 60° N, within the central and northeastern portions of North America, Europe, and Asia. They are rare and isolat ...

South Platte River
The South Platte River is one of the two principal tributaries of the Platte River. Flowing through the U.S. states of Colorado and Nebraska, it is itself a major river of the American Midwestern United States, Midwest and the American Southwestern United States, Southwest/Mountain States, Mountain West. Its drainage basin includes much of the eastern flank of the Rocky Mountains in Colorado, much of the populated region known as the Colorado Front Range and Colorado Eastern Plains, Eastern Plains, and a portion of southeastern Wyoming in the vicinity of the city of Cheyenne, Wyoming, Cheyenne. It joins the North Platte River in western Nebraska to form the Platte, which then flows across Nebraska to the Missouri River, Missouri. The river serves as the principal source of water for eastern Colorado. In its valley along the foothills in Colorado, it has permitted agriculture in an area of the Colorado Piedmont and Great Plains that is otherwise arid. Description The river ...

Lake McConaughy
Lake McConaughy is a reservoir on the North Platte River. It is located north of Ogallala, Nebraska, United States, near U.S. Highway 26 and Nebraska Highway 61. The reservoir was named for Charles W. McConaughy, a grain merchant and mayor of Holdrege, Nebraska, one of the leading promoters of the project. Although he did not live to see the completion of the project, his leadership and perseverance eventually culminated in a public power and irrigation project that helped Nebraska become one of the nation's leading agricultural states. History and overview The lake, formed by Kingsley Dam, is a man-made body of water that is long, wide at its largest point, and deep near the dam (at full capacity) – it was constructed between 1936 and 1941 and is fed by the North Platte River. When full, the reservoir has a capacity of , covers and has of shoreline, making it the largest reservoir in Nebraska. Lake McConaughy was constructed to store water for irrigation for The Tri- ...

Oglala Sioux
The Oglala (pronounced , meaning "to scatter one's own" in Lakota language) are one of the seven subtribes of the Lakota people who, along with the Dakota, make up the Očhéthi Šakówiŋ (Seven Council Fires). A majority of the Oglala live on the Pine Ridge Indian Reservation in South Dakota, the eighth-largest Native American reservation in the United States. The Oglala are a federally recognized tribe whose official title is the Oglala Sioux Tribe (previously called the Oglala Sioux Tribe of the Pine Ridge Reservation, South Dakota). However, many Oglala reject the term "Sioux" due to the hypothesis (among other possible theories) that its origin may be a derogatory word meaning "snake" in the language of the Ojibwe, who were among the historical enemies of the Lakota. They are also known as Oglála Lakhóta Oyáte. History Oglala elders relate stories about the origin of the name "Oglala" and their emergence as a distinct group, probably sometime in the 18th century.

Great Western Cattle Trail
The Great Western Cattle Trail was used during the late 19th century for movement of cattle and horses to markets in eastern and northern states. It is also known as the Western Trail, Fort Griffin Trail, Dodge City Trail, Northern Trail and Texas Trail. It replaced the Chisholm trail when that closed. While it wasn't as well known, it was greater in length, reaching railheads up in Kansas and Nebraska and carried longhorns and horses to stock open-range ranches in the Dakotas, Wyoming, Montana, and two provinces in Canada. It took almost one hundred days to reach their destination. The Great Western Trail ran south of and roughly parallel to the Chisholm Trail into Kansas. The cattle were taken to towns located on major railroads and delivered north to establish ranches. Although rail lines were built in Texas, the cattle drives north continued because Texas rail prices made it more profitable to trail them north. History The Great Western Cattle Trail was first traveled by C ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
