Define a sustainable city.
A sustainable city is one that provides a good quality of life for all residents without using resources that hinder QoL and environmental factors.
What 4 factors make a sustainable city?
Good public transport - don’t need to use their own transport and contribute to emissions.
Good waste disposal
Good services - health and education
Affordable housing.
What is a top-down strategy?
A large scale project involving the government and TNCs, it has little involvement with the people that will be affected.
Name a top-down project in Mumbai, regarding waste disposal and the reason it was instigated.
The Gorai Garbage Site Closure Project.
- Was a full landfill site with waste 27m deep.
- Unpleasant methane smell and toxic gas emission
- 2007 - supreme court ordered for improvements
What took place in the Gorai Garbage Site Closure?
- Garbage reshaped into a hill, covered in lining to prevent leeching.
- Grass planted to create 19 hectare plant
- Methane capture technology generates power.
What are the advantages of the Gorai Garbage Site closure?
- Big budget
- The 18.4 million people are now living with better air quality as less toxic gasses are released
- Recreational park can become a carbon sink.
- Better social connections between people.
- Recyclable energy is being created from the byproduct of landfill.
- Payback time of 2 years. (In 20 years due to the energy scheme they will make a £65m profit).
What are the disadvantages of the Gorai Garbage Site closure?
- Damage of pollution has been done, action should’ve been taken earlier.
- House prices increase in Gorai making it less affordable and hence less sustainable.
- The garbage is still prevalent and more should be done in the cause of recycling.
- Waste is not being managed properly as 17% of the waste is recyclable and 42% is compostable.
Name a top-down project in Mumbai, regarding transport and the reason it was instigated.
The Mumbai Monorail
- Roads getting clogged
- Main use of public transports was the environmentally unfriendly buses that travel very slowly.
- Wanted an alternative mode of public transport.
What took place in the Mumbai Monorail?
- A railway was built in Mumbai over a 5 year period when it should’ve taken 2
- It cost £310 million for the first section to be built.
What are the advantages of the Mumbai Monorail?
- Supposed to reduce congestion and give people an alternative mode of transport.
- Monorail is carbon free (it’s electric), no emissions
- More safe and reliable than road transport, less accidents and more on time.
- Can be constructed in built up areas and can travel consistently at 40mph.
What are the disadvantages of the Mumbai Monorail?
- Only 15,000 people a day use it compared to 6.3million people using the conventional railway.
- Since they charge 10p a ticket, the payback time is 566 years.
- Advantage for tourists, not local people because the route goes through industrial areas not the old city.
Name a top-down project in Mumbai, regarding water supply and the reason it was instigated.
Brihanmumbai municipal cooperation (BMC)
- The reservoirs hold enough water to supply Mumbai with water 24 hours a day but main parts of the city such as the CBD are limited to 6 hours a day.
- Because the pipe network is 100 year old.
- No maps of the network.
What took place in the BMC?
- Constructing 4 new dams adding 2.9 million litres of water daily providing a 24 hour water service.
- Improve the quality of the pipes to prevent leakages.
- Will be completed by March 2018’s.
- Cost £30 million
What are the advantages of the BMC?
- Round the clock clean water supply.
- Pipes are repairable as the network map will be available.
- Jobs created for construction and maintenance.
What are the disadvantages of the BMC?
- Space will taken up
- Greenhouses gasses will be emitted through construction
