  1. 1. HIGHER TIER GCSE Geography Revision
  2. 2. Explain/give reasons: You are now being asked to say why something you have already described is happening. Use ‘because’ to help you answer these questions. There are often two marks awarded for giving just one reason. Where this happens you will be expected to give a simple statement and its elaboration. Command words tell you exactly what type of information the examiner wants. Compare: Write what is similar and different between two pieces of information. Use the word ‘whereas’ to help you compare. Describe: Just write what you see. You may be asked to describe what you see on a photo, graph or map. Do not explain if you are only asked to describe. Justify: You could be asked to justify a decision you have made. Explain your choices in terms of why they are better than other options open to you. Suggest: This is similar to explain but tells you that you are expected to bring in ideas and understanding of our own and is not provided on the paper. What is meant by?: You are being asked to give a definition of a geographical term. You must know the main terms for each of the four Units. When asked for a definition, giving an example is not enough. Measure: You may be asked to measure on a map or graph. Don’t guess – measure accurately using the scale provided.
  3. 3. Papers One & Two Each paper is 90 minutes long and has 90 marks. Once you have chosen a question to answer out of each pair, you will have a little less than one minute per mark. Your examiners will not expect you to write more. Go straight to the point – don’t waffle. Be guided by the marks in brackets as to how many points you need to make. Papers Three & Four Each of these papers is also 90 minutes long but has only 60 marks, so there should be less pressure on time. You will be given advice at the start of each of the three parts it is divided into as to how long you should spend on it. Make sure that you keep to these times. The final ‘problem-solving’ task is in two parts, a table to help you organise your ideas and a final letter or report to write. When completing both, use elaborated statements. They will gain marks. The 2007 Geography exams tests the four units as follows: Papers One & Two Water, Landforms and People Climate, Environment and People People, Work and Development Papers Three & Four People and Place What is the difference between the two exams? <ul><li>The idea of Papers Three and Four is to ask you to solve a problem. In the early parts of the paper you will be introduced to a place and a problem to be solved. You will then be given a number of possible solutions. Your final task on the paper will be to write what you would do and then justify the decisions you have made. The final task is in two parts: </li></ul><ul><li>a table to help you organise your ideas. When filling in the table, make sure you use elaborated, ‘so what’ statements. They will help you gain marks and will make it easier to build up your </li></ul><ul><li>letter or report to describe and explain the decisions you have made </li></ul>
  4. 4. <ul><li>Flashcards : On small cards, summarise a case study into one (or both) sides of the cards and refer to it regularly. Make sure that you include key facts and number as you condense the case study to fit the card. </li></ul><ul><li>Colour coding : colour code large pieces of text into sections. For example, it could be the social, economic and environmental impacts of the London Docklands Redevelopment </li></ul><ul><li>Memory tests : You could look at an important diagram (erg the cross section of a meander) for 20 seconds, then cover it over and draw what you remember. Then give yourself another 20 seconds to see what you missed and add it in. Eventually, you will be able to draw the sketch without looking at a copy. </li></ul><ul><li>Key words test : You could ask someone to read out 10 definitions and you have to say what the key word is. Then you could try it the other way around which is harder with someone giving you a key word to define. </li></ul><ul><li>Spider diagrams (mind maps): Write a key theme in the centre of an A3 piece of paper. Write the sub-themes around it with important ideas and case studies to back them up. Look at the example of migration on the next page to help you. Stick your finished spider diagram somewhere visible where you will be able to refer to it often (e.g. fridge door, bedroom wall). Take a look at the migration spiderdiagram on the next page! </li></ul><ul><li>Practice exam questions : Look at the examples of past case study questions. Practice writing responses to these questions using the flashcards or colour coded case studies you have created. </li></ul><ul><li>Summarising: Condense a section of text into a set number of bullet points. </li></ul><ul><li>Reading aloud: Read a case study summary aloud, then try to say aloud all the facts and figures you remember without the summary. You could also read your keyword lists aloud. </li></ul><ul><li>Repeated writing: Copy out pieces of information more than one time (five times would be appropriate). The repetition will help you to fix the facts in your memory. </li></ul>But I don’t know how to revise! Here are some strategies you could use…

  6. 6. Water, Landforms and People: Keywords Abrasion (or corrasion) : Erosion caused by the rubbing and scouring action of rock fragments carried by rivers. Alluvium : Fine soil left behind after a river floods; also called silt. Attrition: Erosion caused when rocks and boulders, transported by rivers and waves, bump into each other and break up into smaller pieces. Condensation: The cooling of a gas so that it changes into a liquid, for instance as water vapour cools, it condenses to become water droplets, which, when heavy enough, fall as rain. Confluence : The point where two rivers meet. Delta: A build up of sediment at the point where a river meets a sea or lake, due to the water velocity slowing and the river having less energy to carry the sediment. Deposition: The laying down of material carried by rivers or waves. Discharge : The amount of water in a river at a given time, usually measured in cumecs (cubic metres per second) Drainage Basin: The area of land drained by a major river and its tributaries. Also called a ‘river basin’. Drought : A prolonged period of weather that is drier than usual. Embankment: A raised riverbank built to prevent or reduce flooding Erosion: The wearing away of the land by material carried by rivers and waves. Estuary: The point at which a river begins to meet the sea. The river will be tidal, meaning that it will have both salt water and fresh water in it. Evaporation: The process by which liquid, such as water, changes to water vapour when it is warmed. Evapotranspiration: The loss of moisture from water surfaces and the soil (evaporation) and vegetation (transpiration). Flood : The flow of water over an area that is usually dry. Floodplain : The wide, flat area at the bottom of a valley which is often flooded. Groundwater: Water stored underground in permeable rocks. Hydrograph: A graph showing changes in the discharge of a river over a period of time. Hydrological (water) cycle: The continuous recycling of water between the sea, air and land.
  7. 7. Hydraulic action: Erosion caused by the sheer force of water breaking off small pieces of rock. Impermeable: A rock or soil that does not let water pass through it. Infiltration: The downward movement of water that seeps into the soil or a porous rock. Interlocking spur: Ridges of high ground that project into V-shaped valleys. They occur on alternate sides of a valley and interlink. Lag time : The period of time between peak rainfall ad peak river discharge. Levee: An artificial embankment built to prevent flooding by a river or the sea. Meander : The winding course of a river Mouth : The end of the river, where it meets the sea, or a lake. Overland flow: When water flows over the surface of the ground. This occurs for a number of reasons: the soil may be saturated and therefore be unable to absorb any more water; the underlying rock may be impermeable or the ground may be frozen. Oxbow lake: A crescent-shaped lake which has been cut off from the main river channel and abandoned. Percolation : The movement of water through the soil or underlying porous rock. This water collects as groundwater. Permeable : A rock or soil that allows water to pass through it. Precipitation: The deposition of moisture usually from clouds. It includes rain, hail, snow, sleet, dew, frost and fog. Runoff : Rainfall carried away from an area by streams and rivers. Saltation : A process of transportation by rivers in which small particles bounce along the bed. Solution: A type of chemical weathering in which water dissolves minerals in rocks. Suspension: A process of transportation by rives in which material is picked up and carried along within the water itself. Throughflow : The movement of water within the soil sideways, towards the river. Traction: A process of transportation by rivers in which material is rolled among the bed. Transpiration: The process by which water from plants changes into water vapour. Transportation: The movement of materials by rivers and waves. Tributary: A small river that flows into a larger river. Velocity: The speed of the flow of the river V shaped valley: A narrow, steep-sided valley formed as a result of rapid erosion by a stream or river. Waterfall: A sudden fall of water over a steep drop. Watershed: The boundary separating two river basins.
  8. 8. What are the main features of a river? The fastest section of the river, as the channel is widest, with very smooth sides, and the greatest volume of water. The water has increased in speed as the channel widens and becomes smoother. Some boulders cause friction to slow it down a little. Relatively slow moving. Despite areas of fast flowing water, the large amount of material on the river channel bed means that friction will slow the water down. Velocity Deltas; flood plains; levees; meanders; ox-bow lakes Meanders; slip-off slopes; ox-bow lakes Interlocking spurs; waterfalls; V-shaped valley; gorges Features Mainly suspension and solution. Saltation, suspension and solution Traction and saltation Transportation Primarily cuts laterally as it has almost reached base level. The erosive energy of the river is almost totally concentrated on cutting sideways. Much deposition occurs. Continues to cut vertically. But it also begins to cut laterally as it gets closer to base level. Deposition occurs in the slower moving insides of meanders. Primarily vertical erosion, through attrition, abrasion and hydraulic action. Large boulders deposited and eroded in situ. Erosion & Deposition Wide, shallow valley, with large flood plains and meanders. The river channel is wide, deep and smooth sided. v-shaped valley remains with a wider valley floor and the river begins to meander across it. The river channel begins to widen and become deeper. Steep sided v-shaped valley. Thin river channel, deep in places Cross Profile Almost at sea level, very gently sloping towards its mouth Shallow slopes towards the mouth of the river Steeply sloping towards the lower sections of the river Long Profile Lower Course Middle Course Upper Course

  11. 11. CASE STUDY: Lynmouth Flood 15 th August 1952 <ul><li>What were the causes of the flood? </li></ul><ul><li>4 months worth of rain had fallen in the first 2 weeks of August. </li></ul><ul><li>The streams on Exmoor were already full to overflowing. </li></ul><ul><li>The streams dropped over 800m in just 10 miles. </li></ul><ul><li>A storm sat over Exmoor on the evening of the flood and dropped 11 inches of rain in 24 hours. </li></ul><ul><li>Streams flowed down narrow steep sided valleys, crossed by over 30 small stone bridges with limited span. </li></ul><ul><li>Bridges created 'debris dams' as they were blocked by trees and boulders. When they burst they released a shock wave of water which surged down into the village. Around 200,000 tonnes of rock were washed downstream. </li></ul>What were the effects of the flood? 34 people were killed, 28 bridges and 93 houses were totally destroyed or damaged beyond repair. 420 people were also left homeless and 66 cars damaged or washed out to sea. The army helped to evacuate people who were stranded in their homes <ul><li>Why was it such a disaster? </li></ul><ul><li>The normal population of only 450 people had been added to by around 700 holidaymakers. </li></ul><ul><li>Signs such as the discolouration of the water were ignored. </li></ul><ul><li>Houses had been built right up to the river. </li></ul><ul><li>There was no warning system in place. </li></ul><ul><li>A lot of people did not hear the flood warning because it was at night </li></ul>
  12. 12. CASE STUDY: Boscastle Flood <ul><li>What were the causes? </li></ul><ul><li>The day had been very warm, drawing in sea breezes along the coast. When they joined forces with a wet southerly air flow they shot upwards with a dangerous mix of warm, moist, highly unstable air. </li></ul><ul><li>The thunderclouds grew so tall that they created intense rain leading to more than 5 inches falling around Boscastle in just a few hours. </li></ul><ul><li>With the ground already saturated from recent rains, the storm waters were funnelled down steep river valleys and burst </li></ul><ul><li>What were the effects? </li></ul><ul><li>90% of Boscastle’s economy is dependent on tourism. </li></ul><ul><li>After the flood, more than 20 accommodation providers were forced to shut </li></ul><ul><li>Seven helicopters from the Coastguard, the Royal Navy and the Royal Air Force hovered overhead, winching people to safety </li></ul><ul><li>Cars, boulders and uprooted trees were strewn through the streets. </li></ul><ul><li>Cars were swept out to sea, bridges were washed away and people clung to rooftops and trees </li></ul><ul><li>Work has started on new £4.5m flood defences to protect the Cornish village of Boscastle from flooding. </li></ul><ul><li>Background </li></ul><ul><li>Boscastle is situated on the northwest coast of Cornwall, near Bude </li></ul><ul><li>It is situated at the confluence of the River Valency and its tributaries </li></ul><ul><li>It happened on Monday 16 th August 2004 </li></ul>
  13. 13. CASE STUDY: River Nile and the Aswan Dam Background The Nile has been essential in providing water and nutrients for Egypt’s agricultural land. The annual floods led the Nile to deposit nutrients over the land it flooded assisting in the fertilising of crops and land. The irregularity of flooding and growing demands on the Nile for providing water led to the Egyptians wanting to control the Nile. A growing population led to an increase in demand for electricity and agricultural produce. The answer was to build the Aswan Dam. The Aswan Dam was built in 1971. It had a Hydroelectric Power Station and a large lake known as Lake Nasser behind it. <ul><li>The benefits and problems of the Aswan Dam </li></ul><ul><li>Fewer nutrients reaching the sea </li></ul><ul><li>Flood control </li></ul><ul><li>Fewer crops grown for local Egyptians </li></ul><ul><li>River navigable all year round </li></ul><ul><li>Hydro electric power doubles Egypt’s previous output </li></ul><ul><li>In time the lake will silt up </li></ul><ul><li>More income from cash crops of sugarcane, cotton and maize </li></ul><ul><li>Lack of nutrients reaching the sea has affected shrimp and sardine catches </li></ul><ul><li>High evaporation losses </li></ul><ul><li>The large lake can support a fishing industry </li></ul><ul><li>Silt not deposited on flood plains because of flood control meaning fertilisers had to be added </li></ul><ul><li>Increase in Bilharzia </li></ul><ul><li>The Aswan Dam – Facts </li></ul><ul><li>Total cost of building the dam was estimated at over $1 billion </li></ul><ul><li>One third of the cost was provided by Russia </li></ul><ul><li>400 Soviet technicians were employed in the Dams construction </li></ul><ul><li>The Dam was completed in 1968 (but not opened till 1971) </li></ul><ul><li>The dam covers an area of over 480km in length and 16 km wide </li></ul><ul><li>The Hydro Electric producing capacity is 2,100 megawatts </li></ul>
  14. 14. CASE STUDY: A landform formed by deposition – Ganges Delta <ul><li>The Ganges and the Brahmaputra rivers slow down as they reach the mouth. They start to deposit the massive loads of sediment collected on their journeys. </li></ul><ul><li>Now they are one river, but sediment blocks the main path. The river is forced to split its way to the ocean. These channels are called distributaries. </li></ul><ul><li>The Ganges River has eight main distributaries, and there are hundreds of smaller ones. </li></ul><ul><li>The entire delta region covers an area of around 75,000 square kilometres, which makes it the biggest in the world. </li></ul><ul><li>Fertile floodplains </li></ul><ul><li>Bangladesh’s delta is one of the most populated in the world. Many of the country’s 132 million people depend on the delta for their survival. </li></ul><ul><li>Two-thirds of Bangladeshis work in agriculture, and grow crops on the fertile delta floodplains. Jute fibre, used to make twine and sacking, is Bangladesh’s main export crop. </li></ul><ul><li>Farming depends on the annual flooding of the Ganges to bring fresh supplies of nutrient rich sediment to their fields. But living in the path of the Ganges is a dangerous. One way people have adapted to this risk is to build their homes on top of earthen platforms, or embankments. </li></ul><ul><li>Economy </li></ul><ul><li>Fishing has long played a part in the lives of the Bangladeshi people, and its fisheries are the biggest in the world after China and India. </li></ul><ul><li>Where the freshwater of the Ganges mixes with the saltwater of the Indian Ocean, the brackish (slightly salty) water is ideal for producing shrimp by a new and fast-growing type of fish farming called aquaculture. </li></ul><ul><li>Here, high-value fish like shrimp and salmon are farmed in containers or cages that are submerged in the open water. The fish are mainly sold for export. </li></ul><ul><li>Global Warming </li></ul><ul><li>One of the likely results of global warming is a gradual rise in sea levels. This could be 0.5 metres by 2100. It could mean that six million Bangladeshis loose their homes. It could permanently flood the low-lying delta region we have travelled through. It could also increase the frequency of cyclones, and after the timing and severity of monsoons. </li></ul>
  15. 15. CASE STUDY: Drought in the UK, 1995-96 <ul><li>The UK has a temperate climate and can expect to have rain throughout the year – enough to supply the country’s needs. </li></ul><ul><li>Since the 1950s the country has suffered two major droughts causing unexpected problems </li></ul><ul><li>In the north of England water was so scarce that a fleet of 200 tankers working 24 hours a day, 7 days a week was used to transfer water to empty reservoirs. </li></ul><ul><li>1995 and 1996 were the two driest consecutive years for over 200 years. </li></ul><ul><li>What were the short term effects? </li></ul><ul><li>Garden hosepipes were banned and water rationing was introduced </li></ul><ul><li>Clay soils dried out and buildings were damaged as their foundations moved. </li></ul><ul><li>Grass stopped growing, leaving a shortage of cattle feed </li></ul><ul><li>Crops died in the hot, dry conditions </li></ul><ul><li>What were the long term effects? </li></ul><ul><li>Legislation was introduced to try to reduce water consumption by both private and industrial users. </li></ul><ul><li>Water authorities planned to increase water storage capacity and link reservoirs to make transfers easier. </li></ul><ul><li>What were the causes? </li></ul><ul><li>The 1995 &quot;high summer&quot; in the UK was the warmest and driest on record. </li></ul><ul><li>The exceptional warmth began in the last week of June, and the mean July and August Central England temperature was 3°C higher than the average recorded between 1961 and 1990. </li></ul><ul><li>Total England and Wales rainfall for July and August was only 47mm compared to a 1961-1990 average of 139mm. </li></ul>
  16. 16. CASE STUDY: Drought in the Ethiopia, 1983-84 <ul><li>Ethiopia is one of the world’s poorest countries </li></ul><ul><li>Aid came from charities like Oxfam and Band Aid as well as from governments and other organisations. Sadly, civil war and poor transport left much of the donated foodstuffs rotting in ports </li></ul><ul><li>What were the short term effects? </li></ul><ul><li>serious shortage of food and water caused widespread starvation and illness </li></ul><ul><li>about 500 000 people died. The young and elderly were especially affected. </li></ul><ul><li>people migrated from areas that were too remote to receive food aid. Many ended up in refugee camps. </li></ul><ul><li>What were the long term effects? </li></ul><ul><li>up to a million people who were malnourished and poverty stricken continued to need aid </li></ul><ul><li>regular aid from developed countries has imporved agricultural output and provided people with security </li></ul>

Sparsely populated: an area that has few people living in it Suburbanised villages: small settlements which have grown in size and become urban areas in countryside surroundings. Also called ‘dormitory towns’ or ‘commuter settlements’, as many residents who live and sleep there travel to nearby towns for work Suburbs: a zone of housing around the edge of a city Urban growth: the increase in the size of towns and cities Urban land use model: a simple map to show how land is used in a city Urban sprawl: the unplanned, uncontrolled growth of urban areas into the surrounding countryside Urbanisation: the increase in the proportion of people living in towns and cities

  22. 22. CASE STUDY: Urban problems in MEDCs - London <ul><li>There is an estimated 400 homeless people in London every night. Men make up 90% of those sleeping on the streets. </li></ul><ul><li>London produces enough litter to fill an Olympic sized swimming pool every four hours! </li></ul><ul><li>Graffiti artists cost London £100 million a year. This includes removing their ‘art’ from the walls of schools, hospitals and businesses. It means that vital cash is not being used to improve public services. </li></ul><ul><li>High unemployment in inner city areas (where the old industries were once located) leads to social problems. </li></ul><ul><li>The government say a tax of 1p a packet is needed on chewing gum to help pay for the £150 million per year cost of cleaning it off the streets. </li></ul><ul><li>Each year, 2 700 tonnes of smoking-related litter is thrown on London’s streets. </li></ul><ul><li>Air pollution caused by nitrogen dioxide in parts of London is almost three times higher than it should be. </li></ul><ul><li>Rundown areas of London have been awarded a total of £2.5 million in grants to help pay for regeneration projects. </li></ul><ul><li>The most expensive land in the UK is in London and the South East. The price of a hectare of land is now nearly £5.5 million. In 1983, it was just £759 000. </li></ul><ul><li>Experts say that air pollution is quickening the death of 8 000 people per year who are already ill. </li></ul><ul><li>Building new, affordable homes in urban areas is difficult. Land values are very high and land is in short supply. </li></ul><ul><li>Racial tension was to blame for transforming Brixton in south London into a battlefield in 1981. Hundreds of black and white youths attacked the police, set cars alight and looted shops. Over 300 people were injured and an estimated £7.5 million damage was caused. </li></ul><ul><li>Inner city areas are the worst affected by violence, robbery and burglary. </li></ul><ul><li>Traffic is a problem.

  23. 23. CASE STUDY: Migration from Mexico into USA Background In, 1998, there were 5 million migrants into the USA and only one million were legal. Over half, 2.7 million, were from Mexico. Last year there were 356 deaths along the border. The USA claims the main cause was exhaustion. Many try to cross the border in the hope of a better life. The border is 1, 950 miles long and patrolled by armed guards in jeeps, on horses and in helicopters with searchlights. Many become “Jonaleros”, Mexican migrants who wait on street corners in American cities to be collected for work such as painting, moving furniture, gardening and farming. Many try to cross the Rio Grande which forms half of the border to separate the two countries. <ul><li>Why do Mexicans risk their lives to get into the USA? </li></ul><ul><li>Five percent of Mexico’s population are undernourished. This isn’t a problem in the USA. </li></ul><ul><li>88% of people in Mexico have access to safe drinking water. In the USA everybody has access to safe drinking water. </li></ul><ul><li>The average hourly wage in Mexico is $ 3.49 but it is $ 6.75 in California, USA. </li></ul><ul><li>Unemployment is rising in large parts of Mexico. Mining is no longer as profitable. </li></ul><ul><li>The USA government spends more money on education and healthcare than Mexico’s government. </li></ul><ul><li>18% of people in Mexico live on less than 60 pence per day, it is less than 1% in the USA. </li></ul><ul><li>In the USA, 8 out of 10 have a car.

  37. 37. CASE STUDY: Cambridge Science Park <ul><li>The M11 offers a very quick route to London and beyond. </li></ul><ul><li>Stansted airport is 30 minutes down the motorway. There are close links with the university, allowing researchers from there to work in tandem with researchers from the companies of the Science Park. </li></ul><ul><li>Much of the work is research and development in areas such as pharmaceuticals and micro-electronics, from kidney dialysis machines to lasers and computers. </li></ul><ul><li>Established by Trinity College in 1970 on 50 hectares of land, Cambridge Science Park is the UK's oldest and most prestigious science park. </li></ul><ul><li>Now home to 71 hi-tech companies and 5,000 personnel, Cambridge Science Park continues to attract new businesses </li></ul><ul><li>The area is landscaped with trees, lakes and ornamental gardens </li></ul><ul><li>The largest firm employs 320 people but more than half the companies have fewer than 20 people working for them. Most employees are university graduates </li></ul>Why did it locate there? <ul><li>pleasant housing and open space nearby </li></ul><ul><li>good leisure facilities in nearby Cambridge </li></ul><ul><li>near to Stansted airport for international links </li></ul><ul><li>close to M11 and M25 motorways </li></ul><ul><li>working links with other companies on site </li></ul><ul><li>closely linked with excellence of Cambridge University </li></ul><ul><li>highly skilled and qualified workforce available </li></ul><ul><li>room on site for further expansion </li></ul><ul><li>large, flat Greenfield site on edge of city </li></ul>
  38. 38. CASE STUDY: Industry in an MEDC – Osaka-Kobe, Japan <ul><li>Location </li></ul><ul><li>The Osaka-Kobe conurbation is one of Japan’s major industrial areas. </li></ul><ul><li>It is a natural harbour protected from typhoon winds by the island of Shikoku </li></ul><ul><li>Osaka imports many of the raw materials needed in Japan. Many are processed within the port e.g. oil, iron ore. The port is also the outlet for Japan’s exports </li></ul><ul><li>The land is one of the few areas of flat land in a country that is 83% mountainous. </li></ul><ul><li>Land in Osaka Bay has been reclaimed for port development, new industries and an international airport </li></ul><ul><li>It has a population of over 9 million which provides a highly skilled dedicated workforce and a large, wealthy market </li></ul><ul><li>High-tech industries have grown rapidly as a consequence of Japanese inventiveness </li></ul><ul><li>It is the centre of many banks and large Japanese companies </li></ul><ul><li>Thousands of small, often family run, firms. Small firms, usually employing fewer than 6 people, account for 90% of Japanese companies </li></ul><ul><li>Medium-sized companies which, together with small firms, produce 60% of Japan’s manufactured goods </li></ul><ul><li>Large corporations, many of which have become transnationals such as Toyota, Nissan, Panasonic and Mitsubishi </li></ul><ul><li>Up to 11 new science parks have been built in pleasant environments beyond the present urban limits </li></ul><ul><li>Major problem facing Japan is the competition from the NICs, whose labour and other production costs are cheaper. </li></ul>Imports and Exports
  39. 39. CASE STUDY: Industry in a LEDC – Sao Paulo <ul><li>Brazil is the most industrialised of the world’s developing countries – mainly concentrated in and around Sao Paulo </li></ul><ul><li>Sao Paulo’s rapid urbanisation and industrialisation took place during the 1960s and 1970s. </li></ul><ul><li>At this time, half a million people a year migrated to the city looking for work. Today the city has a population of 23 million. </li></ul><ul><li>The region around Sao Paulo had minerals including iron ore and had access to energy resources. This led to the development of iron and steel and engineering industries and the manufacture of machinery, aircraft and cars. </li></ul><ul><li>Brazil is the world’s 9th largest producer of cars. Four large transnational corporations – Ford, Volkswagen, General Motors and Mercedes – all have assembly plants in Sao Paulo. </li></ul><ul><li>Brazilian car workers may earn twice the average Brazilian wage, but to international manufacturers they are cheaper to employ than car workers in developed countries. </li></ul><ul><li>Problems: Heavy industry and traffic have caused air pollution; the great number of cars has led to gridlock; and the location of commercial buildings (e.g. banks) and offices has created a ‘sky scraper jungle’, high land prices and a lack of open space. </li></ul><ul><li>Some industry has moved to new towns. These have been made to attract industry, by building major roads and locating in a cleaner, less congested environment. </li></ul><ul><li>Jundaia is a new town 100km from Sao Paulo. Several transnational companies have already located there, including Pepsi. Despite using mostly machinery, it still employs 350 people. </li></ul><ul><li>Pepsi workers not only have a regular job with regular pay, they also get free lunches and free medical care. Many people living and working in Jundaia are experiencing a rising standard of living – although others still have to seek low paid jobs. </li></ul><ul><li>Nearer the CBD, some of the increasing wealth of the city is being used to turn run down areas into modern business, retail and leisure centres. However, this usually takes place by clearing existing favelas. </li></ul><ul><li>One third of Sao Paulo’s population are still employed in the informal sector – recycling materials, repairing goods, processing and/or selling food. They are not enjoying a rising standard of living. </li></ul>
  40. 40. CASE STUDY: Ford – a transnational company <ul><li>Ford corporation originally located in Detroit in the 1980s. By the late 1990s, it was: </li></ul><ul><li>Manufacturing and/or assembling cars worldwide. Bulk parts were produced in MEDCs such as the USA and Japan </li></ul><ul><li>Increasingly locating it new factories in LEDCs such as Brazil </li></ul><ul><li>Increasingly making parts in several countries so that each particular model is no longer made in one country (reduces strikes) </li></ul><ul><li>Facing increased competition, especially from Japanese manufacturers. </li></ul><ul><li>Working in Detroit with its previous rivals, Chrysler and General Motors, to produce a car that will use less fuel, cause less pollution and challenge Japanese cars. </li></ul><ul><li>Detroit – motor city </li></ul><ul><li>Henry Ford saw Detroit as an ideal location for the world’s first mass production line. </li></ul><ul><li>He built his factory on flat land next to the Detroit River at the heart of the Great Lakes waterway system. </li></ul><ul><li>Steel was produced on an adjacent site using relatively local iron ore (brought by ship) and coal (brought by train). </li></ul><ul><li>Ford developed a large local market by paying his workers $5 a day, when the national average was $9 a week, enabling them to buy their own cars. </li></ul><ul><li>High wages attracted workers from all over the world. Later, Chrysler and General Motors located their main factories in Detroit. </li></ul>
  41. 41. CASE STUDY: Malaysia – a newly industrialised country <ul><li>Since 1990, Malaysia’s annual economic growth was averaged 8%. This has been done without high inflation or unmanageable foreign aid. Much of this has been due to government policies. </li></ul><ul><li>‘ Malaysia Inc.’ is the governments aim of turning Malaysia into a fully industrialised country by 2020 (an MEDC) </li></ul><ul><li>In 1983, the decision was made to privatise many of the industries and economic sectors. Government policy changed to one based on rapid industrialisation to one that should be successful and sustainable. </li></ul><ul><li>The government is investing less money in industries that require large workforces and more in ones where the emphasis is on technology. </li></ul><ul><li>A government ‘Technology Action Plan’ covers automated manufacturing, micro electrics, biotechnology and information technology </li></ul><ul><li>In 1997, there was little unemployment – in fact the country has to rely on migrant workers from Indonesia and the Philippines. </li></ul><ul><li>It has attracted many foreign investors and high-tech firms, and is building a new international airport, a new town and several science parks. </li></ul><ul><li>In 1985, the government founded the Proton car company </li></ul><ul><li>By the mid-1990s, industry was confined to specifically designed areas such as the new town of Shah Alam. Firms locating here did not have to pay taxes for the first 10 years. This encouraged many of the world’s transnationals to locate there. </li></ul><ul><li>Malaysia has embarked on a series of expensive ‘prestige’ projects including the Petronas (the world’s tallest building in 1998) </li></ul>
  42. 42. CASE STUDY: Iron and steel industry in South Wales <ul><li>1850 – mid-20 th century </li></ul><ul><li>The valleys of South Wales were ideal for iron making. Coal and iron ore were found together on valley sides </li></ul><ul><li>The valleys led to coastal ports where iron products and surplus coal were exported to many parts of the world. </li></ul><ul><li>The industry was centred on areas like Ebbw Vale and Merthyr Tydfil </li></ul><ul><li>By 1850 there were 35 ironworks in the area. Whole villages, built in a linear pattern, were totally dependent on the local ironworks. </li></ul><ul><li>After 1860, steelworks replaced iron foundries due to an improvement in iron smelting. </li></ul><ul><li>1970s onwards </li></ul><ul><li>By the 1970s, there were only two steelworks left in South Wales. They were not in the valleys but on the coast at Port Talbot and Llanwern. </li></ul><ul><li>The initial advantages for steelmaking had gone. Only a few coal mines remained open and the iron ore had long since been exhausted. </li></ul><ul><li>Raw materials needed importing – better to locate new modern steelworks on the coast at break of bulk locations. This is when a product has to be transferred from one form of transport to another – a process that takes up time and money </li></ul><ul><li>It was easier and cheaper to have the new steelworks where imported raw materials were unloaded. </li></ul><ul><li>it was also a government decision as they were financially helping to locate new sites on the coast </li></ul><ul><li>Port Talbot is one of Britain’s three remaining integrated steelworks and uses the latest technology. Integrated means all the stages in the manufacture take place on the same site </li></ul><ul><li>the Llanwern works was closed in 2001 due to overseas competition, global overproduction and a fall in the price of steel. </li></ul>Port Talbot
