why did Nissan open a car factory in Sunderland?
there is a huge market for cars in Europe
by building in the UK they avoid EU trade restrictions from importing from outside the EU
British government provided 20 million pounds and lowered taxes and 20 million from european bank
why were the British government keen to invest in Nissan building a car factory in Sunderland?
it was an area of high unemployment (ship yards and coal mines had shut down causing a circle of decline)
allowed Nissan to buy land at cheaper agricultural land price rather than more expensive industrial land prices
what about the land site made it appealing to Nissan?
Large area of flatland
available at a lower price
room for expansion onto farmland(greenfield)
close to Newcastle airport
what about the labour made it appealing to Nissan to locate to Sunderland?
skilled, reliable and loyal labour force
large unemployed labour force in local residential areas (Hyton Castle)
access to A19 and M1 for employees
what about the potential market made Sunderland appealing to Nissan?

benefit from providing services to plant eg. cleaning
more disposable income
able to expand and open new businesses due to increased demand (MULTIPLIER EFFECT)
how the local government affected by the car plant?
increased revenue from businesses and increased employment means more taxes
have money to improve services in the area eg. roads
how are the national government affected by the car plant?
helps lower the unemployment problem in the north east
higher exports help balance net trade
how are environmentalists affected by the car plant?
concerned about expanding onto greenfield site (green land)
Nissan invested in 6 wind turbines to generate 6% of power
this reduces carbon dioxide emissions by 4,000 tonnes per year
what is a multinational company/transnational companies?
a business that has its facilities and other assets in at least one country other than its home country
usually have centralised head offices where they coordinate global management
explain the steps of the circle of decline
1. industry closes
3. people have less disposable income
4. less demand for services eg. cinemas so they close
5. less money to the local government from business and council tax
6. area looks run down as less money is spent on improving it
7. the area becomes a less desirable industrial location
explain the multiplier effect
1. new industry is set up
2. creates jobs
3. people have more disposable income
4. more demand for luxury industries so more open eg.cinemas
5. more money to local government from income and business taxes
6. more money it spent on improving services
7. the area becomes a more desirable industrial location
why did Nissan location to Chennai?
labour costs are lower in India - makes Nissan more competitively priced
there is a rapid growth in car ownership in India - big domestic market
Chennai has a population of 4.4 million - potential labour
Chennai is a city on the east coast - materials can be transported easily
what are the local and national advantages to India of Nissan locating to Chennai?
200,000 cars are made every year here
directly employes 3,000 people
indirectly employes 6,000 people
Nissan pays money on its profits to local government
jobs provide decent wages - increased standard of living and disposable income causing the multiplier effect
Nissan has improved road access to the area
the plant has great health and safety
the plant is environmentally friendly - 70% of the rain used has been rainwater harvested
provides formal jobs so tax is paid to local government
what are the disadvantages to India as a result of Nissan locating to Chennai?
employees being exploited - not paid as well as in MEDCs
the plant has increased traffic and pollution to an already overcrowded city
some of the profits go back to Japan (called LEAKAGE) not all money stays in India
producing cars requires a high amount of energy causing pollution
if demand for cars falls the plant could close causing a circle of decline
environmentalists are concerned that more car ownership will increase global warming and could negatively affect the climate in India

the farmers receive and extra $150 per tonne of cocoa, this is about 10 cent more than the usual price on the world market
they receive a social premium so they can fund community project eg. schools
farmers receive training to help them deal with pest or diseases eg. black pod
members of the co-operative can borrow small amounts of money from a micro-credit bank known as Kuapa Kokoo credit union
the farmers are elected as trusted member of the village to weigh and record their cocoa beans. making trade more offical, people more accountable
Kuapa Kokoo are shareholders in Divine Chocolate Ltd, profits from sales go back into Ghana projects
what are the problems for cocoa farmers in Ghana?
price of cocoa is falling, earning less than 60p a day
cost of living is increasing

in 200 years
when the glaciers start retreating?
how much of the hydroelectric power created is a surplus?
what is isostatic rebound in terms of Iceland?
the land is bouncing back from having the weight of the heavy ice removed
it is now much higher than sea level
but the sea level could rise much quicker than the ground
why is Iceland ideal for computer servers?
they can be kept from overheating from Iceland's cool climate
also the surplus of electricity makes it cheaper
is Iceland likely to flood?

describe the changes in Iceland`s fishing industry
due to the warming sea sea mackerel move north to Iceland
Icelanders are fishing them
EU set a quota on how many they are allowed to fish
what is Iceland's population?
where does Iceland's prevailing wind come from?
warm moist wind from the south west
crossed the Atlantic Ocean and the North Atlantic drift making warm and moist
what current affects the south and west of Iceland?
Irminger current - a warm sea current
where is the coldest part of Iceland?
central highland (vatnajäkull)
snowfall adds to the ice caps
how does Iceland's climate vary?
north - drier (500mm) and colder (Jan -2.2 degrees) because its in a rain shadow
south - wetter (1600mm) and warmer (Jan 1.3 degrees)
how does Iceland's climate affect farming?

too cold for wheat, grass grown for hay to feed sheep
farmers overcome the climate by farming in glass houses heated by geothermal heat
rural to urban migration resulting in low property prices in rural areas
how has Iceland's climate effected tourism?
seasonal - most visit in the short summer
growing industry and very important
how has Iceland's climate affected transport?
internal flights easier than driving in winter
ice and snow make mountain roads impassable in the winter
mountain roads are dangerous in winter as vehicles have to cross rivers filled with melted water from glaciers

a tax placed on energy bills so that money can be invested in cleaner renewable energies
proving unpopular in the UK due to the rising energy prices
what is the kyoto protocol?
an international agreement (USA didn't sign) to set targets to reduce greenhouse gas emissions
where is `cap and trade` used?
in the US and EU
what is cap and trade?
countries are set a limit to how much greenhouse gas emission they are allowed (carbon credits)
if they have credits left over they can sell them to countries that aren't going to meet their limit
what is the problem with cap and trade?
the original cap was set depending on how polluting the country was originally
the worst companies start off as the best
companies that have to buy more carbon credits put their prices up making consumers pay more!
in theory there is an economic incentive to reduce pollution
what type of climate does the tropical rainforest have?
what are the temperatures like in the tropical rainforest?
high and constant - range of 2 degrees
the sun has a high angle in the sky
evening temps - rarely below 22 degrees

Transamazonian highway is the longest at 5300km - built to develop the region and transport timber
900km of railway from Carajas to the coast
small airships have been built
how has settlements caused deforestation in the Amazon?
the development in Amazonia has led to an increase in population 2-30million
large parts of the forest were cleared to make room for settlements such as Maraba and Carajas
what 4 things have caused deforestation in the Amazon?
how have resources caused deforestation in the Amazon?
Timber - mainly hardwoods, obtained by logging companies that sell trees in developed countries
Minerals- provides the region with a vast natural resource iron ore, bauxite, manganese, diamonds, gold and silver (have to mined)
HEP - land has to be cleared to make the dam causing flooding
what are the impacts of deforestation on the indigenous people of the Amazon?
the Amerindians may have to move from their ancestral homes due
loss of animals and plants could be their food source
their traditional lifestyle, customs and religious beliefs may have to be changed
how would deforestation affect the food web?
there would be less producers
leading to less consumers as not enough food - could cause extinction
what impacts does deforestation have on the quality of the soil in the Amazon?
there are less trees to intercept
the rain floods the land taking all the soils nutrients with it (LEACHING)
fewer trees means less humus (decayed leaves) is created so less nutrients are added to the soil
the soil is poorer quality due to lack of nutrients
what impacts have deforestation had on the climate of the Amazon?
the canopy layer has been removed - no more interception and more water gets lost by surface runoff into rivers
lack of shade has increased temperatures on the forest floor
how have buttress roots adapted to the Amazon?
only need shallow roots to get nutrients
the roots stretch from the ground to 2 metres up to help support the tree
how has a jaguar adapted to the Amazon?
has strong claws to help climb the canopy layer
pattern fur for camouflage
excellent vision for hunting in the dark on the forest floor
how have lianas adapted to the Amazon?
wood vines that start at the ground level and climb up to the canopy for sunlight
how is the howler monkey adapted to the Amazon
strong arms to swing in the canopy trees
tail to help balance
how tall is the amazon rainforest?
what are solutions to deforestation in the Amazon?
what is agroforestry and how is it a solution to deforestation in the Amazon?
a variety of crops are planted so the soil is never bare and is not as easily eroded
some of the canopy layer is left to protect the soil - canopy trees intercept daily rainfall so the soil isn't leached and therefore doesn't become infertile
encourages poor farmers to use alternative methods of cultivation
what is afforestation and how is it a solution to deforestation in the Amazon?
established timer plantations replant trees that are cut down and stop illegal logging
all timber products from sustainable sources
what is education and how is it a solution to deforestation in the Amazon?
teaches people the importance of the rainforest
what is carbon credit and how is it a solution to deforestation in the Amazon?
rich industrialised countries pay Brazil to set aside rainforest
this is to offset the carbon emissions from he rich countries
what are national parks and how is it a solution to deforestation in the Amazon?
uses law to protect some areas of the forest from economic development eg. Jaù national park - located in the Amazonas state in Brazil
it is the largest forest reserve in South America
what is ecotourism and how is it a solution to deforestation in the Amazon?
stay in lodges made from trees which are replanted
eat local food
learn local traditions and educate yourself about the rainforest
lodges are powered by renewable energy sources eg. solar panels
facilities are usually basic - water is conserved
what is location of Manaus?
1300m north west of Brasilia, north Brazil, Brazil is on the east coast of South America
on confluence of river Negro and Amazon
8 by 8 miles of urban area
what is the population of Manaus?
what are the main industries in Manaus?
farming in surrounding areas
what are the impacts and management of timber?
deforestation has become popular to make room for the growing population
encourages illegal logging - offer a higher wage, made easy from lack of law enforcement
in 2001 trade of Mahogany was banned - "mahogany mafia" cut mahogany trees down and sell them for $50 each
lack of trees decreases interception causing leaching of the soil and causing the soil to become infertile
lack of trees also affects the ecosystem - decreases biodiversity
Greenpeace have blocked exported of illegally logged trees
employed "forest police" to stop mahogany mafia but the vast forest makes it difficuly
what are the impacts and management of farming?
swelling population - pressure to make enough food
deforestation - fertilisers are added to add nutrients back into the soil
chemicals from fertilisers easily flow into the rivers - polluting them
endangers animals such as the pink river dolphin
the university of Manaus and the rainforest alliance (an NGO) are encouraging farmers to stop agroforestry
what are the impacts and management of tourism?
many people come to experience the diverse wildlife of the Amazon by jungle trekking
many of the guide are only interested in the $$$ not preserving the wildlife
tours can be destructive to habitats
ecotourism - brings money to economy helps to raise the SOL for the locals
describe the process of acid rain
1. power stations, factories and cars cause pollution
2. chemicals such as sulphur dioxide and nitrogen oxide rise into the air
3. chemical changes produces acid (sulphuric and nitric acid)
4. acid polluted air is blown by the wind
5. water droplets in the air become polluted
6. acid rain falls to the ground
7. trees and vegetation become polluted and die
8. water and soil is polluted by acid
describe the distribution of acid rain in Europe
the highest concentration (4.3pH) concentrated around the scandinavian countries, coasts of Belgium and Holland, countries found on the Baltic Sea
lower concentrations around cities such as Luxembourg, Minsk and Vilnius
how is pollution (from industries) transported?
why pollution levels high in Europe?
Western Europe has a high population and high energy use
what are the effects of acid rain on trees?
acidic water dissolves the nutrients and minerals
no branches, bark or leaves (defoliation)
aluminium is leached out of the soil - damages the tree because its toxic
inhibits the leaves from functioning
different species are more sensitivity
doesn't kill the tree - weakens and limits nutrients available to them
what are the effects of acid rain on lakes?
decreases biodiversity - different species are sensitive to different pH
aluminium increases the pH decreases - causes chronic stress which lowers fishes body weights and size, making them less competitive for survival
what are the effects of acid rain on water supplies?
leads to upset stomachs
what are the effects of acid rain on soil?
low pH rainwater increases leaching - valuable nutrients are lost leaving it infertile
a low pH soil can directly inhibit the growth of new vegetation
what are the effects of acid rain on buildings/statues?
botanic gardens - harder parts of the limestone stick out
turns green from bronze
traps in dirt and then flakes off leaving a hard crust
limestone is easily eroded
pock marks - little impressions in the rock
corners aren't sharp
eg. house of commons
explain how individuals can prevent acid rain
replace catalytic converter to reduce carbon emissions
explain how industry can prevent acid rain
using alternate energy sources: wind turbines
by "scrubbing" remaining pollutant from factory chimneys
explain how government can help to prevent acid rain
introduce an act to reduce carbon emissions
"liming" - adding lime to soil or lakes to neutralise the acid
