The Society for the Promotion of Area Resource Centres (SPARC) has forged an alliance with the National Slum Dwellers Federation (NSDF) and Mahila Milan to tackle housing and infrastructure issues for the urban poor. NSDF organizes and mobilizes the urban poor to articulate their concerns and find solutions to the problems they face, while Mahila Milan supports and trains women's collectives to administer and manage community resources and participate in NSDF activities. SPARC provides the necessary administrative, financial, policy, documentation and other support. The alliance covers issues such as housing, savings, credit, infrastructure and city development.
