But Sonawane and others like her were often treated like the garbage they collected.

Urban Transformations: In Durban, Informal Workers Design Marketplaces Instead of Getting Displaced by Them

The story of how Warwick Junction bucked the global trend of replacing informal markets with malls and shopping centers is a testament to the compromise, conflict, and resourcefulness of a small set of actors – informal workers, local officials and the small non-profit Asiye eTafuleni (Zulu for “bring it to the table”).
