Lesson 2-Consequences of Urbanisation Flashcards
Urban Sprawl
Is defined as the spread of an urban area into the surrounding countryside.
Negative impacts of urban sprawl
- Requires lots of new infrastructure, less economically efficient to service low density rural areas compared to compact urban areas
- The main cause of animal wildlife habitat loss
- Causes more commuting from the suburbs and therefore more fuel consumption and traffic congestion
Where do slums develop?
On the edge of cities or in areas of low land value.
Therefore prone to environmental hazards like flooding
Slum data in 2017-2030?
- 2017-900 million lived in slums
- 2030-1/4 people will live in a slum
Why people disagree with the term slum housing?
In Mumbai, some people see it as a political label so others refer to them as homegrown neighbourhoods
CASE STUDY URBANISATION-Mumbai
- Home to Dharavi slum that holds over 1 million people- Asias biggest slum
- Located on prime real estate in the centre of Mumbai
Challenges in Mumbai
- Economic/Social divide
- Sanitation issues
-lack of basic ammenities
-unreliable water supply - Lots of waste
- $86 a month salary average
- Danger-inacessble
Shortage of housing in HIC’s
- Shortage of affordable housing is the key problem
- In London, average house prices rose by almost 70% between 2010 and 2019 due to migration, gentrification and the purchasing of property by wealthy foreign investors
Lack of urban services and waste disposal
- Financial restraints in LIC’s results in a lack of basic services like water and electricity
-maintenance of infrastructure is also limited and results in traffic congestion, polluted water, flooding and spread of disease
- In 2015 only 5% of piped water supply reached slum areas in 42 Indian cities and towns
Unemployment and under-employment
- Unemployment rates typically high
-people may be employed in ‘informal jobs’ like a street vender - Under-employment commonly occurs when migrants move and are desperate for a job
Transport issues
- Urbanisation and Suburbanisation have led to increased traffic in cities across the world
-congestion and pollution - Car boom in the 60’s-more roads were built to compensate but acctually did the opposite as it attracted more people
CASE STUDY SUBURBANISATION Los Angeles (USA)
- Issues of transport in HIC
- Infrastructure couldnt keep up with rapid population growth
- Didnt build enough free ways
- Worst city in the world for traffic
Ways of combatting bad congestion?
- Congestion pricing -pricing through specific areas
- Wider road lanes
How are the challenges different in HIC’s and LIC’s?
- Affordable housing in HIC’s and acctually sufficient housing in LIC’s
- Transport issues in both
- HIC’s face a bigger problem of unemployment and underemployment
- LIC’s face a bigger lack of urban services and waste disposal
How does level of development affect the challenges in cities?
- HIC’s have more funding to be able to afford better infrastructure and housing
- LIC’s face a greater lack of basic ammenities due to their small spending capabilities
