Dharavi is one of the largest slums in Mumbai, India, with a population between 600,000 to over 1 million people. It provides cheap housing for many migrant workers and is home to thousands of small businesses recycling waste and producing goods for export. Various plans have been proposed since 1997 to redevelop Dharavi into formal housing and end the slum conditions, but all have faced opposition from current residents concerned they will not be adequately rehoused or their businesses relocated. Sanitation is a major issue in Dharavi due to lack of toilets and illegal housing.
