The Society for Promotion of Area Resource Centres (SPARC) is one of the largest Indian NGOs working on housing and infrastructure issues for the urban poor. SPARC works in partnership with two community based organisations - the National Slum Dwellers Federation (NSDF) and Mahila Milan (MM). Collectively we organise hundreds of thousands of slum dwellers and pavement dwellers to address issues related to urban poverty, and collectively produce solutions for affordable housing and sanitation.
