S: solution, plan
O: opportunities, potential Area – just over 7.6 million km2
population - 24 million; only 3 people per sq km
similar land area to USA, but over 10x fewer people –
Topic 1.1 Population Dynamics majority around SW & E coast
main industries- mining, agriculture, steel
Over populated: export surplus food, energy and mineral resources
Bangladesh 13th largest economy; 5th highest per capita income

158 million - population
Pop. Growth: 1.1%
1.6% - population growth rate
1020 people per sq km – population density 6% unemployed only
City of Dhaka: 15000 per sq km 99% are literate
40% unemployed R: vast arid areas in central and NW Australia:
142 on HDI (human development index) extreme temperatures (over 40°C),
5.7 death rate infertile soil
5.07% infant mortality rate
periodic droughts
R: lack of knowledge about contraception
R: uneducated - 48% access to water difficult and expensive
R: majority of pop. work in primary sector especially E: 90% of land uninhabited
subsistence farming which large families are useful for E: net migration of 5.74
R: lack of proper health system and vaccinations O: resources not fully exploited Australia can support a
R:high death rate much higher population
R:high infant mortality rate O: high educational standards -> universities in large
E: increasing pop.
cities can attract graduates from around the world
E: over-cultivation -> loss of soil fertility; farmers poor,
cannot replace nutrients in the soil -> insufficient O: space! although majority of land is desert there are
supply of food -> malnutrition, a constant issue in rural vast areas of suitable land for living
areas S: Govn. encouraged immigration by relaxing visa
E: migration from rural to city -> pressure on resources regulations and targeting skilled workers from Asia
like housing, healthcare, education etc. S: Govn. offered financial incentives to foreign
E: more competition for jobs -> high unemployment -> companies to set-up in Australia ->more jobs for
elevated crime rate & drug trafficking
Aussies and immigrants
E: inadequate water supply; unhealthy living conditions
E: Increased levels of pollution in air, water, noise, soil S: 2011 Govn. funded a parental leave scheme for 18
S: improve general education weeks for parents earning less than $150,000/year
S: provide family planning education
S: encourage use of contraception - make condoms
widely available
S: give incentives for having fewer children
S: develop health care
S: develop industry
S: develop infrastructure in rural areas that will improve
access to schools and health care

Social Problems:
TOPIC 1.6 Urban Settlements -Increased congestion -> increased pollution ->
health problems
Urban area – London: -Increased travel time
Capital of United Kingdom, along the River Thames -More cars –> increased frequency of accidents
-More traffic jams -> increased frequency of road rage.
Changing land use - East Londen Docklands -development on greenfield sites -> conflicts with user
Formerly one of the world's most important docks groups (e.g. dog walkers & farmers), and high demand
-containerization->cargo ships too big to navigate the on amenities (e.g. Epping forest)
Thames Environmental Problems:
-many factories closed & moved overseas (offshoring) -loss of habitats, reduce biodiversity
-Docklands->declined->unemployment->whole area -Increased amount of air and noise pollution
became deprived -> a twilight zone on edge of CBD -Air pollution can -> acid rain and greenhouse effect
with derelict land, high crime -Increased development -> destroy greenfield sites
London Docklands Development Corporation (LDDC) -Concrete and removal of trees -> a heating effect –
set up in 1981->regenerate docklands of East London 10oC higher than in the countryside

Economic Problems:
-loss of farmland to development
-Increased government expenditure on infrastructure
-Workers arrive late to work
Solutions:
-Congestion charge: Drivers are now charged to drive
into the center of London.
TOPIC 2.1 Earthquakes & Volcanoes
-Bike hire scheme: Borrow bikes for a short period at
minimal cost & bike lanes created
Earthquake: Japan 2011
-Trams (buses that run on train tracks) reintroduced
-Removing cars from certain roads and making them
walking-only areas. -8.9 earthquake on Richter Scale
-Park-and-ride facilities on outskirts -2:46pm(local time) Friday 11th March 2011
-Extended rail & underground decrease travel times -72km East of Tohoku (East coast of JPN)
-The amount of buses has been increased and -depth 24km below surface
hydrogen-powered cell buses were introduced -Oceanic Pacific plate subducted under Eurasian plate
-Encourage carpooling and building dedicated lanes
(a slip of 50m)
-Increased car tax and petrol duty
Management and protection of coastline: Positive Impacts NIKE has on LEDCs (benefits)
Groynes: of rip-rap (loose stone) or timber, built -provides jobs that develops country's economy
perpendicular to beach to interrupt longshore drift -healthcare benefits for workers
Sea walls – of concrete or stone, to separate land and -managers/skilled personnel trains locals=upskilling of
water areas and prevent coastal erosion and flooding workforce
due to wave action -incr. countries exports=raises GDP
Gabions – wire cage filled with stone for erosion -improve infrastructure (building roads, electricity
control supply)
Revetments – of steel or rock, sloping structures -May attract other companies to set up in area
placed on dunes or at foot of cliffs to absorb the energy
of incoming water Negative Impacts NIKE has on LEDCs (drawbacks)
at Easington, need of strong protection (revetments) -noise, water air pollution=result of production
due to gas terminal -low wages to workers=exploiting locals
-little incentive to provide good working conditions

TOPIC 3.3: An Industrial Zone Or Factory TOPIC 3.4: Area where Tourism is important
TOPIC 3.5: Energy Supply In A Country Or Area -no network to transmit power from North Sea
windfarms constructed yet
Germany:
•largest consumer of electricity in Europe
•main sources (>80%): coal, nuclear and gas TOPIC 3.6: Water Supply In A Country Or Area
-all renewable energy sources produce <20%
Location of largest power stations: Lesotho/South Africa:
•next to rivers, coasts and coalfields Lesotho is a land-locked country completely bordered
•this saves transport costs - coal transported on rivers by South Africa.
•rivers supply cooling water Country with highest average elevation in the world.
•near coasts, keep air pollution away from settlements LEDC with pop. of 2 million.
•large areas of flat land for construction Receives high rainfall - a water surplus country.
-e.g. River Ems, River Elbe and River Neckar • Most of Lesotho consists of highlands which receive
Coal (45%) e.g. Schwarze Pumpe Power Station high rainfall, so valleys are ideal for building dams and
Advantages – reservoirs
-Germany has large reserves of brown coal in the east The Lesotho Highlands Water Project is the largest
-import black coal cheaply civil engineering project and water transfer scheme in
-coke can also be used for making steel Africa
Disadvantages – -it is an ongoing project
•air pollution – green house gases • After taking for own use, Lesotho will sell water to
•transport can be costly, but Germany -> use rivers South Africa where demand is greater than supply
-deep mining dangerous, but Germany has open-cast • When completed, it will divert 40% of Senqu
-open-cast -> visual polution (Orange) River’s water through 5 large-scale dams and
Nuclear (23%) e.g. Isar 2 Nuclear Power Plant a series of tunnels to deliver water to the Vaal River
Advantages – System in South Africa.
•very little uranium needed to make lots of electricity Advantages -
•no greenhouse gases means no acid rain • long term income for Lesotho
•no global warming Climate friendly! - infrastructure was developed where there was none
•highly regulated -improved communication for villages in mountains
Disadvantages – • Generates HEP from Katse dam – 100% of demand
decommissioning costs are very high • Lakes attract tourism
•security always a concern – terrorist target -job creation
•capital costs were very high -royalties paid to Lesotho government have reached
•radioactive waste is hard to dispose of much of the population
•large disasters could happen Disadvantages –
-comes to an end in 2020 Only 9% of Lesotho is arable. Where the dams are
built was farmland which a few hundred households
Germany is currently investing in renewable sources relied upon for subsistence agriculture. They were
•obtains from solar, wind and hydro power compensated and relocated. Finding suitable and
•plans to add 5000mW of solar capacity available land was difficult.
•largest wind-power producer in EU (9% of total energy Managagement –
produced in Germany) -water is rerouted to supply Maseru (capital of L) in
- wind turbines in the Black Forest and off-shore in times of shortage.
Baltic Sea and North Sea - water is discharged from the dams to preserve
•Black Forest elevation is suitable for wind turbines ecological balances down-stream
Advantages –
-nuclear disasters avoided
-security problems decreased
-no pollution, climate friendly
•300,000 jobs created in renewable energy
Disadvantages –
-less energy produced than from non-renewables
- expensive technology and high capital input
-consistent power production not reliable
-considered visual pollution by some Germans (hence
off-shore windfarms)
