Dharavi, Asia’s largest slum, with a population of 1 million spread over 530 acres and contributes about 500 million to India GDP, became famous when some smart entrepreneurs started the concept of slum tourism. Now the latest tourists are none but visitors from premier business schools.

These dusty, dirty, often-stinking, narrow lanes, crowded with houses of tin or tarpaulin sheets, have suddenly become an international tourism hotspot and this time the state government is welcoming them with a grin. Because the visitors represent elite institutes like London School of Economics, Rockefeller Foundation, United Nations and Nagoya University, Japan, all trying to understand the method in the madness.[via]
