Central Place Theory
Central place theory is an urban geographical theory that seeks to explain the number, size and range of market services in a commercial system or human settlements in a residential system.Goodall, B. (1987) The Penguin Dictionary of Human Geography. London: Penguin. It was introduced in 1933 to explain the spatial distribution of cities across the landscape. The theory was first analyzed by German geographer Walter Christaller, who asserted that settlements simply functioned as 'central places' providing economic services to surrounding areas. Christaller explained that a large number of small settlements will be situated relatively close to one another for efficiency, and because people don’t want to travel far for everyday needs, like getting bread from a bakery. But people would travel further for more expensive and infrequent purchases or specialized goods and services which would be located in larger settlements that are farther apart.

Technology
Technology is the application of knowledge to reach practical goals in a specifiable and reproducible way. The word ''technology'' may also mean the product of such an endeavor. The use of technology is widely prevalent in medicine, science, industry, communication, transportation, and daily life. Technologies include physical objects like utensils or machines and intangible tools such as software. Many technological advancements have led to societal changes. The earliest known technology is the stone tool, used in the prehistoric era, followed by fire use, which contributed to the growth of the human brain and the development of language in the Ice Age. The invention of the wheel in the Bronze Age enabled wider travel and the creation of more complex machines. Recent technological developments, including the printing press, the telephone, and the Internet have lowered communication barriers and ushered in the knowledge economy.

Saffron Walden
Saffron Walden is a market town in the Uttlesford district of Essex, England, north of Bishop's Stortford, south of Cambridge and north of London. It retains a rural appearance and some buildings of the medieval period. The population was 15,504 at the 2011 census. History Archaeological evidence suggests continuous settlement on or near the site of Saffron Walden from at least the Neolithic period. It is believed that a small Romano-British settlement and fort – possibly in the area round Abbey Lane – existed as an outpost of the much larger settlement of Cestreforda to the north. After the Norman invasion of 1066, a stone church was built. Walden Castle, dating from about 1140, may have been built on pre-existing fortifications. A priory, Walden Abbey, was founded under the patronage of Geoffrey de Mandeville, 1st Earl of Essex about 1136, on the site of what is now Audley End House. The abbey was separated from Walden by Holywell Field. After the dissolution of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haverhill, Suffolk
Haverhill ( , ) is a market town and civil parish in the county of Suffolk, England, next to the borders of Essex and Cambridgeshire. It lies about south east of Cambridge, south west of Bury St Edmunds, and north west of Braintree and Colchester. Geography The town centre lies at the base of a gentle dip in the chalk hills of the Newmarket Ridge; running through the town is Stour Brook, which goes on to join the River Stour just outside the town. Rapid expansion of the town over the last two decades means that the western edge of Haverhill now includes the hamlet of Hanchet End. The surrounding countryside largely consists of arable land. History Haverhill dates back to at least Anglo-Saxon times, and the town's market is recorded in the Domesday Book (1086). Whilst most of its historical buildings were lost to the great fire on 14 June 1667, one notable Tudor-era house remains (reportedly given to Anne of Cleves as part of her divorce from Henry VIII and thus titled ''A ...

Ely, Cambridgeshire
Ely ( ) is a cathedral city in the East Cambridgeshire district of Cambridgeshire, England, about north-northeast of Cambridge and from London. Ely is built on a Kimmeridge Clay island which, at , is the highest land in the Fens. It was due to this topography that Ely was not waterlogged like the surrounding Fenland, and was an island separated from the mainland. Major rivers including the Witham, Welland, Nene and Great Ouse feed into the Fens and, until draining commenced in the eighteenth century, formed freshwater marshes and meres within which peat was laid down. Once the Fens were drained, this peat created a rich and fertile soil ideal for farming. The River Great Ouse was a significant means of transport until the Fens were drained and Ely ceased to be an island in the seventeenth century. The river is now a popular boating spot, and has a large marina. Although now surrounded by land, the city is still known as "The Isle of Ely". There are two Sites of Sp ...

East Anglia
East Anglia is an area in the East of England, often defined as including the counties of Norfolk, Suffolk and Cambridgeshire. The name derives from the Anglo-Saxon kingdom of the East Angles, a people whose name originated in Anglia, in what is now Northern Germany. Area Definitions of what constitutes East Anglia vary. The Anglo-Saxon Kingdom of East Anglia, established in the 6th century, originally consisted of the modern counties of Norfolk and Suffolk and expanded west into at least part of Cambridgeshire, typically the northernmost parts known as The Fens. The modern NUTS 3 statistical unit of East Anglia comprises Norfolk, Suffolk and Cambridgeshire (including the City of Peterborough unitary authority). Those three counties have formed the Roman Catholic Diocese of East Anglia since 1976, and were the subject of a possible government devolution package in 2016. Essex has sometimes been included in definitions of East Anglia, including by the London Society of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Fens
The Fens, also known as the , in eastern England are a naturally marshy region supporting a rich ecology and numerous species. Most of the fens were drained centuries ago, resulting in a flat, dry, low-lying agricultural region supported by a system of drainage channels and man-made rivers ( dykes and drains) and automated pumping stations. There have been unintended consequences to this reclamation, as the land level has continued to sink and the dykes have been built higher to protect it from flooding. Fen is the local term for an individual area of marshland or former marshland. It also designates the type of marsh typical of the area, which has neutral or alkaline water and relatively large quantities of dissolved minerals, but few other plant nutrients. The Fens are a National Character Area, based on their landscape, biodiversity, geodiversity and economic activity. The Fens lie inland of the Wash, and are an area of nearly in Lincolnshire, Cambridgeshire, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polders
A polder () is a low-lying tract of land that forms an artificial hydrological entity, enclosed by embankments known as dikes. The three types of polder are: # Land reclaimed from a body of water, such as a lake or the seabed # Flood plains separated from the sea or river by a dike # Marshes separated from the surrounding water by a dike and subsequently drained; these are also known as '' koogs'', especially in Germany The ground level in drained marshes subsides over time. All polders will eventually be below the surrounding water level some or all of the time. Water enters the low-lying polder through infiltration and water pressure of groundwater, or rainfall, or transport of water by rivers and canals. This usually means that the polder has an excess of water, which is pumped out or drained by opening sluices at low tide. Care must be taken not to set the internal water level too low. Polder land made up of peat (former marshland) will sink in relation to its prev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
