Issues in poor countries cities

Squatter settelment- areas of city 9usually on the outskirts) that are built buy people of any material they can find on land thst doesnt beling to them. Such settelments have different names in different parts of the world (favela Brazil) they are often known as shanty towns.

Improving Conditions

2 main ways 

1) Self Help 

  • People in squatter settlements help themselves. Improving houses make them more permanent.
  • Help form local authority- standpipes for clean water electricity supplies.
  • Schools and heath centers.

2) Site and Service 

  • local authorities build purpose built slums.
  • Plan the lay out e.g road structure.
  • Tanks on the roof collect clean rainwater.
  • Electricity supplies.

Problems

1) Environmental diasters

  • poor health and safety regulations 
  • rapid urbanisation 

Bhonal, Indian 1984

  • Posinous gas escaped from chemical plant and killed 3000 people.
  • Unafficial estimates 8000 to 10000 killed.
  • 50000 suffered from perminant disabilities.

2) Electronic Waste 

  • Computers need to be disposed of safely 
  • Computers dumped in river

India Brain drain

  • Imports over 4.5 million new computers a year

Problems

3) Water Pollution

  • Water for toilets,drinking,washing.
  • Cows in river Ganges River

4) Waste Pollution

  • E-waste
  • River as toilet 
  • Industrialisation=waste dumped by factories.

Shanghai

  • 30,000 tonnes of waste/day
  • Industry=70% of CO2 emmisions 
  • 73% of electricity produced by coal
  • 400,000 deaths annually
13 of 21

Reducing the Problems

1) Waste Pollution

Shanghai

  • Burn 7500 tonnes of waste a day
  • Children&adults scavange for materials and reuse and re-sell them.
  • Effective solid waste disposal unit has been installed in most homes.

2) Air pollution

Encourage people to use technology that reduces emmisions of sulphur dioxide and nitrogen oxide. transport is also monitored.

  • China & India use coal for 80% of electicity.
  • China's industry uses low sulphur coal.

Reducing the Problems

3) Water Pollution

  • 1986 Gonga action plan introduced water treatment works on River Ganges in India.
  • Shanghai the Huongnu and Suzhau rivers have been targeted for improving quality.

London Rich country/Sustainable living

Problems

  • Congestion is growing in outer London town centres.
  • Rain services are in unprecedented crisis. crowded and unreliable

5 priorities to improve transport 

  • Reduce traffic congestion.
  • Overcoming the backlog of investment on the underground so as to safely increase capacity and reduce overcrowding.
  • Improvements to bus station services: reliability
  • Better intergration: reduce overcrowding, increase safety, high frequency 'turn up and go'

Sustainable Urban living

There are 5 ways in which cities can make themselves sustainable.

Sustainable city- An urban area where residents have a way of life that will last a long time. The environment is not damaged and the economic and social fabric, due to local involvement are able to stand the test of time.

1) conserving the historic environment.

Protecting a cities historic building e.g listed building Liverpool

  • Waterfront and areas associated with it's development were designated a world herritage site in 2004.
  • St.Georges Hall
  • India Building 

Advantages of Brownfeild Sites- Reduces commuting and traffic congestion, prevents urban sprawl, country side is not built on, areas on the edge of the city can be used to provide leisure opportunities, leads to contaminated or unsightly sites being cleared, reduces waste land in cities.
