Dharavi, Mumbai, India
Population: 1 million
In Dharavi, where
Slumdog Millionaire was filmed, thousands of small businesses thrive. The slum has an informal economy with an estimated $1 billion annual turnover.
Residents have opposed attempts to develop Dharavi, which sits on prime real estate in India’s financial capital, Mumbai.
"People think of slums as places of static despair as depicted in films such as
Slumdog Millionaire," said Sanjeev Sanyal, an economist and writer.
"If one looks past the open drains and plastic sheets, one will see that slums are ecosystems buzzing with activity... Creating neat low-income housing estates will not work unless they allow for many of the messy economic and social activities that thrive in slums," he said.
