26
Q

Intensive farming

A

Involves the concentration of inputs to create artificial ecosystems such as greenhouses and poly-tunnels.

27
Q

Extensive farming

A

Where vast areas of land are in use.

28
Q

Causes for the deforestation of tropical rainforests:

A

Demand for hardwood timber and the desire to use land originally covered by trees commercially.

29
Q

Types of rural areas

A

Remote countryside, accessible countryside, commuter belt and urban fringe.

30
Q

Sub-Urbanisation

A

Building of new homes on the outskirts of a city or town, these homes are often larger and spaced apart.

31
Q

Greenfield sites

A

Land not designated for development but for parklands.

32
Q

Commuter belt

A

Lies just beyond the urban fringe, people living in the commuter frequently travel large distances to work in cities/towns.

33
Q

Reasons people may want to live in the commuter belt:

A

Price of land (cheap), availability of good transportation and better quality of life/air quality.

34
Q

Accessible countryside

A

Countryside within a day’s trip of nearby cities and towns.

35
Q

Main uses of accessible countryside:

A

Farming, recreation and leisure and retirement.

36
Q

Changes in the use of farmland

A

Mechanisation, agglomeration (development of agro-business), repurposing of farmland to: tourist destinations and retirement locations.

37
Q

Agribusiness

A

Field of study relating to agriculture – development of agribusiness reflects the more scientific, profit-driven attitude which has influenced recent agricultural changes.

38
Q

Reasons for change in developing and emerging countries:

A

Economic development, technological development, population growth and rural-urban migration.

39
Q

Aspects of sustainable rural living:

A

Environmental (ensuring that natural resources will continue to exist for the next generation), economic, social (offer a good QOL and infrastructure).

40
Q

Examples of intergovernmental organisations helping manage rural challenges

A

World bank (provides financial and technical assistance), UNESCO (provides education) and World Health Organisation.

41
Q

Examples of NGOs (charities) helping manage rural challenges

A

Oxfam, WWF and Doctors without Borders.

42
Q

High rates of urbanisation occur because:

A

Most economic development is concentrated in large cities and cities are experiencing high rates of natural population growth.

43
Q

Agglomeration

A

The concentration of people and economic activities in favourable locations.

44
Q

Conurbation

A

When towns/cities which are close to each other join together.

45
Q

Counter Urbanisation

A

Occurs when cities grow very large and rural-urban migration patterns reverse.

46
Q

Urban Regeneration

A

Re-using abandoned areas of cities (due to counter urbanisation).

47
Q

Urbanisation of suburbs

A

Occurs when development restrictions are relaxed allowing for the construction of high rise buildings and commercial districts etc.

48
Q

Factors affecting the rate of urbanisation

A

Pace of economic development and the rate of population growth.

49
Q

Megacity

A

City with over 10 million inhabitants.

50
Q

Global or world cities

A

Hubs in growing economies and are well recognised – they can have any population. Examples include: Rio Di Janario and Sydney.

51
Q

Problems associated with rapid urbanisation:

A

Development of shanty towns, poor access to water and electricity, traffic congestion and poor transportation, poor health infrastructure, poor education infrastructure, poor employment opportunities (and lots of informal employment), social problems and environmental issues.

52
Q

Land use patterns emerge because of:

A

Land values, location needs and accessibility.

53
Q

Structure of a city:

A

Core (oldest part of the city - contains the CBD), inner city ring (early suburbs and some business use), suburban ring (housing is the dominant land use) and urban fringe (eroded countryside as the city spreads outwards).

54
Q

Deindustrialisation

A

Transition away from capital intensive manufacturing and towards services.

55
Q

Squatter settlements

A

A collection of homes built on unowned or unused land – they are illegal, often dangerous places to live and are built from scrap materials.

56
Q

Types of pollution in urban environments:

A

Air pollution (e.g. burning fuelwood and congested traffic), visual pollution (graffiti and litter), noise and smell pollution.

57
Q

Push factors to the urban fringe:

A

Housing is old, congested and relatively expensive (in the urban environment), environmental pollution and shortage of land for business use.

58
Q

Pull factors to the urban fringe:

A

Larger houses, parking and commercial land us is easier and closeness to major arterial roads.

59
Q

Retail parks

A
