Dharavi, in the heart of Mumbai, is supposed to represent the quintessential Asian slum. Crowded streets and busy markets; domestic workshops cheek by jowl with sweatshops producing both real and fake Pepe jeans; brick houses rising as high as their microscopic footprints allow; high-rises mushrooming here and there like gigantic shacks; schools in Kannada, Tamil, Hindi, English, Marathi, Urdu, and other languages, usually with more than 50 pupils per class; temples of every Buddhist and Hindu denomination; flamboyant mosques so crowded that people have to pray on the streets,old churches with full congregations – remnants of the region’s seventeenth-century Portuguese history – and new evangelical missions converting low-caste Hindus by the dozen; community toilets that double up as marriage halls; piles of garbage waiting to be picked over by scavengers; open drains running along narrow back streets; thousands of water pipes branching off in every direction.
