Urban Issues & Challenges
A growing percentage of the world’s population lives in urban areas – global pattern/trend
Urban = town/city.
Urbanisation = the proportion of the world’s population who live in cities.
HIC = High Income Country with a GNI per capita higher than $12746. For example The UK.
LIC = Low Income Country with a GNI per capita lower than $1045. For example Afghanistan.
NEE = Newly-Emerging Economies are countries that have begun to experience high rates of economic development, usually along with rapid urbanisation. For example Brazil and Nigeria.
A growing percentage of the world’s population lives in urban areas – global pattern/trend
Urbanisation is faster today in LIC/NEE than in HIC.
A growing percentage of the world’s population lives in urban areas – factors affecting the rate of urbanisation
Rural-urban migration = the movement of people from the countryside into towns and cities.
Natural increase = where the birth rate is higher than the death rate.
Push factors = factors that push people out of the countryside.
Pull factors = factors that attract people to a place.
A growing percentage of the world’s population lives in urban areas – factors affecting the rate of urbanisation
Push and pull factors
Farming is hard and
poorly paid.
Desertification and soil
erosion also make
farming difficult.
These areas are isolated
due to poor roads.
Farming is often
subsistence level, which
means that only enough
food is produced to
feed the family, nothing
left to sell.
There are better paid
jobs.
A higher standard of
living is possible. There
are also better medical
facilities.
There is a better chance
of getting an education.
Drought and other
climate hazards reduce
the number of crops
that grow.
There are few doctors
or hospitals.
Poor harvests may lead
to malnutrition or
famine.
Schools provide only
the very basic
education.
Public transport is
better and the area isn’t
isolated.
They have friends and
family already living
there.
A growing percentage of the world’s population lives in urban areas – emergence of megacities
Cities with a population of over 10 million. In 2015 there were 28 of these megacities and the United Nations estimates that by 2050 there may be as many as 50. There are three types of megacity; slow-growing, growing, and
rapid-growing.

Urban growth creates opportunities & challenges for cities in LICs & NEEs – importance of the city regionally,
nationally & internationally
Regionally = relating to a particular area or district in a country.
Nationally = Relating to the whole country.
Internationally = Relating to other countries.
Rio is Brazil’s second most important industrial centre, producing
5% of Brazil’s GDP.
Stunning natural surroundings and amazing beaches (such as Sugar
Loaf Mountain and Copacabana Beach) make it one of the most
visited cities in the southern hemisphere.
It’s 5 ports and 3 airports allow for exports such as coffee, sugar
and iron ore.
Rio hosted matches during the 2014 World Cup and will host the
2016 Olympic Games.
The Statue of Christ the Redeemer is one of the Seven New
Wonders of the World.
The main services in Rio are finance, banking and insurance.
The main manufacturing industries are chemicals, pharmaceuticals,
clothing, furniture and processed foods.

Social = Something that affects people Economic = Something that affects the economy of the area
World Cup 2014 and Olympics 2016 have been hosted in Rio. This has provided the area with many jobs, especially in construction and tourism. Over 90,000 jobs are expected to be created in 2016.
Clean water has been provided in many areas. This has given people a better quality of life and helped to reduce the spread of diseases such as cholera, therefore improving people’s health and reducing the death rate.
People have access to hospitals, such as Sao Lucas Hospital, Copacabana. This means that more people have access to healthcare and medicines. Many people relocate to Rio for this reason.
Many businesses, such as Nestle and Texaco have located to Rio. This has created many jobs for people and attracted people to the area. In 2011 when Nestle opened over 1000 jobs were created.

Urban growth creates opportunities & challenges for cities in LICs & NEEs – how urban growth has created challenges
Challenges Description of the challenges Solutions
Health care In 2013 only 55% of the city had a local family health clinic. Services for
pregnant women and the elderly were very poor, especially in poorer
areas of the city near to Rocinha.
Health kits to peoples’ homes, especially in the poorer areas. There
are also vaccines and medicines now available. This has meant that
the infant mortality rate has fallen and life expectancy has
increased.
Education Education in Brazil is only compulsory up to the age of 14. Only half of
children continue their education beyond 14. Many get involved in drug
trafficking. The main reasons for poor education are; shortage of schools,
lack of money and need to work, and shortage of teachers.
Authorities have tried to improve access to education for everyone
by; encouraging local people to volunteer and help in school.
Water
Supply
Around 12% of Rio’s population did not have access to running water. It is
estimated that 37% of water is lost through leaky pipes, fraud, and illegal
access.
Seven new treatment plants were built. By 2014, 95% of the
population had a mains water supply.
Energy Rio suffers from frequent blackouts due to a shortage of electricity. The
growing population and the demands from holding the Olympics have
made the situation worse. Many people in poorer areas try to get
electricity illegally, which is very unsafe.
Electricity supply to Rio has been improved by; installing 60km of
new power lines, building a nuclear generator, and developing the
new Simplicio hydro-electric complex which will increase Rio’s
supply by 30%.
Urban growth creates opportunities & challenges for cities in LICs & NEEs – how urban growth has created challenges
Unemployment &
Crime
Robbery and violent crimes are very common in Rio. Street crime is
a problem at night and violent gangs control drug trafficking in
many of the favelas.
Since 2015 unemployment levels have been rising. The poor people
who live in favelas are still without jobs and unemployment rates
are over 20%. Most work in the informal sector, making money
wherever they can, such as street vending. This is very poorly paid
work.
Education is being used to reduce youth unemployment. The Schools
Tomorrow programme aims to improve education in poor and
violent areas. There are practical skills courses as well as courses for
adults. Free child care is available for teenage parents so they
continue in education.
In 2013 Pacifying Police Units (UPPs) were established to reclaim
favelas from drug dealers. Police have now taken control of different
areas around Rio and the crime rate has fallen.
Air Pollution &
Traffic Congestion
Air pollution is estimated to cause 5000 deaths per year. This is due
to heavy traffic causing air pollution.
Improvements have been aimed at reducing traffic congestion.
Expansion to the metro systems and new toll roads (pay to drive on)
in the city centre to reduce congestion.
Waste and Water
Pollution
Favelas (squatter settlements) are built on steep slopes access is
very difficult for waste collection. Most waste is dumped and also
pollutes the water system.
Overseas aid has been used to reduce the amount of sewage. 12 new
sewage works have been built since 2014. A power plant has also
been set up near the University of Rio. This uses 30 tonnes of
rubbish every day to produce gas and provide electricity for 1000
homes.

Poorly built from materials such as iron, broken bricks and plastic sheets.
Illegal
Landslides on the slopes when there is heavy rainfall
Limited access due to the steepness of the slopes.
12% of homes don’t have running water. Residents usually have to make several trips per day to access clean water.
30% have no electricity and will connect illegally to the electricity pylons
50% have no sewage connections.
Unemployment rates higher that 20%
Many jobs are in the informal sector where the average income is less than £75 per monthMany people turn to drugs to make money and the drug gangs dominate the favelas
Murder rate is 20 per 1000
Infant mortality rates are 50 per 1000
Waste cannot easily be disposed of and builds up
Causes diseases such as cholera to spread.
Health and breathing issues caused by burning rubbish
PROBLEMS

SOLUTIONS http://www.bbc.co.uk/education/guides/zk32pv4/revision/11
Self-help schemes
• Small scale projects which allow local
people to use their skills to help improve
their local area.
• The government has provided materials
such as bricks, cement and glass to enable
residents to improve their own homes.
• This often creates a community spirit as
many families work together to make the
improvements.
• In Rocinha, self-help schemes have
improved the area from slums to low
quality housing where the majority of
homes have basic services like electricity.
• There are now also many services in
Rocinha including cafes and shops.
Site and service schemes
• Undertaken by the local authority to
relocate residents from favelas.
• Brick houses are built with electricity,
running water and sanitation pipes.
People may be allowed to buy these
houses.
• An example is 'The Favela Bairro Project'
or 'Slum to Neighbourhood' project.
• Services in these areas also include
rubbish collection, schools and health
centres. A Pacifying Police Unit (UPP) has
been set up. This involves police walking
around to reduce crime.
Charities
• Self-help schemes.
• The Developing Minds Foundation
builds schools and supports
education programmes in Rio's
favelas.
• Their aim is to improve the literacy
rates of children so they can get a
good job, improve their standard of
living and have more life choices.

Economic growth – businesses creating jobs and money
Urban change in cities in the UK leads to social, economic, & environmental opportunities & challenges – impacts of national
& international migration
Impacts of migration
• These migrants are a hard-working and motivated workforce, improving the levels of skills in the economy
(more plumbers).
• This helps where there are shortages of these skills in Bristol.
• Migrants have enriched the city’s cultural life. Fifty countries are represented in Bristol’s population. These
migrants contribute to the cultural life of the city in music, art, literature and food.
• Bristol’s large African and Afro-Caribbean population has had a significant impact, and has created a strong
community spirit.
• The St Paul’s Carnival attracts around 40,000 people each year. Its aim is to help improve relations
between European, African, Caribbean and Asian communities. Younger migrants help to balance out the
ageing population and they add money to the local and national economy, by paying taxes.
Urban change in cities in the UK leads to social, economic, & environmental opportunities & challenges – opportunities in
Bristol
Bristol’s youthful population
means that there is a vibrant
underground music scene.
There are a variety of venues
for entertainment including
The Bristol Old Vic.
Shopping is a growing leisure
activity in Bristol. The retail
park, Cribbs Causeway. They
have also improved the city
centre by adding CCTV,
improving public transport
and turning the Old Market
area into a conservation area.
Every primary school pupil
planted a tree to improve the
city’s green coverage.
Bristol is home to global
companies, such as Aardman
Animations. Companies are
attracted for reasons such as
having close links to the
university and having a skilled
workforce.
The Ministry of Defence
Procurement Agency (DPA) is
located in Bristol, employing
over 10,000 people. It supplies
the army, air force, and navy
with everything from boots to
aircraft carriers.
At Bristol’s Harbourside old
factories and warehouses
have been converted into bars
and nightclubs. This includes
an art gallery and the At-
Bristol science exhibition.
175 businesses in Bristol have
a ‘Green’ action plan and the
first 100 electrical car charging
points were installed in the
city.
High-tech companies are very
important. There are 50
micro-electronic and silicon
design businesses in the
Bristol area.

Urban sustainability requires management of resources and transport - features of sustainable urban living - water & energy
conservation, waste recycling, & creating green spaceA sustainable urban area = minimal damage to the environment, the economic base is sound with resources allocated fairly and jobs secure, and there is a strong sense of community, with local people involved in decisions made. https://www.youtube.com/watch?v=KpUfrDsA3oM
• Fire station was given a biomass boiler. • Thick double glazed houses with walls and solar panels. • Free loft insulation.• Special showers and toilets to save water. • Kerbside recycling. • Master Composters Scheme – people encouraged to make their own compost. • Surrounded by natural habitats and wildlife. • Allotments to cut down food miles. • Wildlife corridors with paths so animals can move around the town and people can take
walks.

Aims to reduce high traffic
flow in the central area of
London by charging people to
drive through these areas. The
standard charge is £11.50 for
each day.
Schemes including ‘go drive’
and ‘DriveNow’ encourages
people to car share.
Making public transport more
effective. Buses, the underground,
trains, trams and the river bus
service are all linked so that there
are smoother running times.
Traffic is restricted in certain areas.
The scheme, known as ‘mini Holland’
means that the areas are bike and
pedestrian friendly. London cycle
hire scheme is also available for
people to hire bikes.
50 bus priority schemes have been
introduced in the capital. This
means that roads within the city
centre can only be used by buses.
Parking costs have been increased in
the city centre. However, this has been
teamed with controlled parking zones
in the outer areas of London. Parking
has been increased in these areas to
encourage the use of public transport.
