Environmental
Mexico City- overcrowded &polluted (just breathing in the air is like smoking 20 cigarettes a day)
Large, open spaces to deal with the large population
Cultural
Standard of living: incomparable to the USA
Way of life and standard of living is much better in the USA
Impacts
Consequences on Mexico
Consequences on USA
Social
Negative: a female heavy population structure
Negative: ↓BR = lower population
Negative: Racial TENSION & DIVISION
Economic
Negative: Economy ↓ as those migrating out were the key contributors
Positive: Men can send back money earned in the USA to their family and friends back in Mexico
Positive: migrants fill up all the jobs that the Americans don’t want, helping the economy- they are essential to the growth of the country.
Environmental
Positive:↑ environment& ↓ air pollution as the population decreases
Negative: Increased population: overcrowding and increased pollution
Cultural
Negative: Culture of Mexico could potentially diminish
Positive: migrants return with new skills
Positive: America can gain new cultures

3. Unit 2: Strategies to influence population change : China
Background to the “One Child Policy”
In the early 1900s = China was in stage 1-2 of the DTM, large families were encouraged by Govt. to↑ the workforce needed for industrialization.
BR & DR high
China industrialised & agriculture produced higher yields and public health improved → DR quickly ↓ hence, THE POPULATION SKYROCKETED.
People made no effort to lower the birth rates due to the benefit (and longstanding culture) of having children for labour, particularly in rural areas where un- mechanised subsistence farming took place.
In the 1950s the pop. growing at a very high 1.9% a year
Events:
1975 The Chinese government started “Wan xi Shao” – “Later, Longer, Fewer” publicity campaign – not very effective
1979 The “One-child policy”.
Inducements: free education/priority housing/pension & family benefits
Fines on families that had further children
“granny spies” & “female infanticide”
Effects:
Pop growth rate ↓ to 0.7%, China = stage 3 of the DTM. There were, however,
Negative effects : 90% of foetuses aborted were female → man > women by 60 million.
Tradition of large families is steadily disappearing

4. Unit 2– LEDC Rio De Janeiro Problems With Large LEDC Cities
Population – 11,500,000
Crime
Associated with organised crime, violence and drugs. Favelas are areas of high crime rates, but are becoming safer places as community spirit increases.
Wealthy residents are moving out of Rio to safer areas.
Tourists told not to take valuables e.g. jewellery to beaches.
Housing
500,000 homeless in Rio.
>1,000,000 people live in favelas.
1,000,000 in low quality authority housing Favela= residential area which lacks basic services e.g. water & electricity + no legal right to the land
Often built on steep slopes from any available materials.
Flash floods and mudslides can carry houses away after heavy rainfall. 200 people were killed after storms in 1988.
Attempts have been made to clear the favelas in the past, but the evicted returned and rebuild.
Local authorities now accept the presence of the favelas and work with the residents to improve them.
Traffic
Surrounding mountains don’t allow the city to expand. Little space for improving the traffic network.
= traffic congestion, pollution and large amounts of noise during much of the day/night.
Pollution
SMOG = Industrial pollution + traffic fumes
Beaches + sea are also polluted.
There is no refuse collection in some parts of the city, such as the favelas
Open sewers in Favela = serious health hazards, e.g. cholera in 1992.

5. Unit 2– Improving Rio’s shanty towns – LEDC cities
Rochina - favela
Self-help Schemes
People work together to build their homes
Authorities provide breeze-blocks for walls and roof tiles.
The money saved by not having to pay for labour is used to provide amenities such as electricity, a clean water supply, tarred roads and community centre.
Low-cost Community Housing Projects
Low cost homes can be built with cheap breeze-blocks.
Water tank on the roof collects water for use in an indoor sink and bathroom/toilet.
Electricity and mains sewerage are added. The inhabitants mostly have jobs, making them able to pay a low rent.
The 'Favela-Bairio' programme
Favelas need support from outside.
Since 1995, the Rio city authorities invested to improve favelas.
Financial backing from the Inter-American Development Bank →Rio city authorities have spent $500,000 on the 'Favela-Bairio' programme
Aim to improve the services and infrastructure in 300 of Rio's favelas.
The programme promotes self-help amongst favela residents, building on the strong community spirit that exists there.
City authorities discuss and negotiate with the local community committees to find the best ways in which local people can help themselves.
