Case study 16: Rapid urban growth, problems and conflicts over land usage in Mumbai, India Flashcards
How has rapid urbanisation lead to water pollution in Mumbai?
Pollution of Mithi river (runs through Mumbai): industries use it as waste disposal+ airport dumps untreated oil.
800 million of untreated sewage go into the river per day.
Toxic rubbish is also disposed there.
How has rapid urbanization lead to increase flood risk in Mumbai?
Solid rubbish blocks the river’s drains + plants grow there.
e.g. 2005 Mithi river flooded when only 1 metre of rain fell in 24h.
406 people died and it cost 100 million US$.
What are the solutions to solving Mumbai’s water pollution + flood risk?
River engineering: dredged to make it deeper so increase its capacity; widened + obstacles removed; Banks were smoothed so that the river could get quicker to the sea.
Public toilets built.
Education projects set up.
How has rapid urban growth lead to atmospheric pollution in Mumbai?
As Indian economy grows, more electricity is needed, so more fossil fuels (coal) burned, so greenhouse gases released: CO2 + CH4 + SO2 (from sulphur impurities in fossil fuels).
Traffic and congestion: lack of catalytic converters in cars engines form nitrogen oxides.
What are the solutions for Mumbai’s atmospheric pollution?
New metro system, proposed by Prime Minister Manmohan Sinh.
Diesel has been banned.
Roads fixed so less congestion so less pollution.
What is Vision Mumbai?
Plan that aims to demolish buildings and sell it to settlement developers for cheaper price. This settlement developers would build better homes to residents and also profitable commercial buildings, stimulating the economy.
aims to reduce by 90% the amount of people living in slums housing, such as in Dharavi.
What is the problem with the Vision Mumbai plan?
People would be left homeless while the land is being developed. an economic crisis might slow down the process of remodeling Dharavi due to a lack of capital.
