KAKADU URANIUM MINE, N.T (AUSTRALIA)Australia is home to around 40% of the world’s uranium reserves and currently supplies around 20% of the global market.From 2000 to 2005 nearly 50,000 metric tonnes of Uranium oxide were exported from Australia to eleven different countries. This brought over A$2.1 billion dollars to the Aust. economy

SOLAR POWER TOWER, SEVILLE (SPAIN)Towers receive the focused sunlight from mirrors. Flat, movable mirrors focus the sun's rays upon a collector tower (the target). Concentrated solar thermal is seen as one viable solution for renewable, pollution free energy.The heat produced, heats saltwater, turns turbines and produce electricity.

FAVELA, RIO DE JANIERO (BRAZIL)• Favelas were the place where former slaves with no land ownership and no options for work lived. Over the years, many freed
black slaves moved in. • Most modern favelas appeared in the 1970s, due to rural exodus, when many people left rural areas of Brazil and moved to
cities. • Residences are built without permission or a license and are often disorganised, without numbered streets, sanitation networks,
electricity, a telephone service or plumbing. In recent years favelas have been troubled by drug-related crime and gang warfare.

RURAL & URBAN ENVIRONMENTSTHINK PAIR SHARE
• Write down a definition of rural and urban environments
• Write down as many examples of each of these environments
• What are basic facilities that humans need?
• What are basic services that should be accessible in human envrionments?

A SETTLEMENT HIERARCHYType of Settlement Population Description
Conurbation 3-10 million A group of large cities and their suburbs
Metropolis/ Metropolitan area
1-3 million A large city and its suburbs
Large city 300,000 to 1 million A city with a large population and many services; usually capital cities
City 100,000 to 300,000 Abundant services
Town 1000 to 100,000 Few services
Village 100 to 1000 Limited services
Hamlet 10 to 100 0 services likely
Isolated dwelling Less than 10 1-2 buildings and families
URBAN
RURAL
11
Regions located outside cities and towns with a low population density, few buildings/homes and limited businesses/services.
Agriculture is the primary industry in most rural areas, although other human activities may include forestry, tourism, mining, fishing.
Settlements: hamlets, villages, towns
Rural regions differ because of geographic characteristics• Relief• Climate • Human activities• Social characteristics e.g. culture, wealth
RURAL ENVIRONMENTS
12
TYPES OF AGRICULTURE• Compare the following terms using pg. 115
– Arable farms and Pastoral farms– Intensive farming and Extensive farming– Subsistence farming and Commercial farming
• Arable farms: grow crops e.g. sugar canes, pineapples, cotton• Pastoral farms: rear animals e.g. lambs, dairying cows, llamas• Intensive farming: farms with a high level of input such as labour, fertilisers and
pesticides to achieve a high output (yield per hectare)• Extensive farming: farms with a low level of input and output per hectare, e.g. cattle
station• Subsistence farming: farming family consumes what is produced and any surplus is sold
or bartered. • Commercial farming: farms that sell a majority of their produce

SUBSISTENCE FARMING IN TIBET (CHINA)Tibet is the highest region on earth, with an average elevation of 4,900 metres.The economy of Tibet is dominated by subsistence agriculture; due to limited arable land, the primary occupation of the Tibetan Plateau is raising livestock, such as sheep, cattle, yaks, camels and dzo.

URBAN ENVIRONMENTS• Regions located in a town, city, metropolitan area or
conurbation with a population greater than 1000 peopleABS
• Urban environments are generally non-agricultural, and have abundant services such as education, healthcare, public transport, entertainment and retail.

PATTERNS OF GLOBAL URBANISATIONSource:: (Fig 6.4) Textbook pg. 116Describe the locations of the earth’s highest and lowest levels of urbanisation

PUSH/ PULL FACTORS
18
Push factors
• Reasons for people to leave rural regions
Pull factors
• Reasons that attract people to cities
• What push and pull factors can you think of for rural-urban migration?
• Ben’s push/pull activity
19
MIGRATION TO URBAN (OR RURAL) ENVIRONMENTS
Push factors• Industrialisation has reduced the
need for farm labourers• Declining rural services• Unemployment• Low commodity prices• Debt• Poverty• Drought or bushfire or flooding• Salinity• Crop failure, Food shortage,
famine• High crime• War/ conflict
Pull factors• More job opportunities• Opportunity to increase income• Higher standard of living• Access to education• Access to housing• More services• Improved living standards• Better health services• Wider lifestyle opportunities • Good climate• More fertile land• Improved safety• Political stability• Reduced risk of natural hazards
