But in India, young people living in slums are using their sketching skills to spur urban change. As part of a broader civic campaign centered on "child clubs," groups of children are creating detailed "social maps" of their marginalized neighborhoods to voice their concerns about public space, as first reported in Citiscope, a CityLab partner site.

The information void stood in stark contrast to the hundreds of thousands of people living in Kibera, ironically tucked away between some of the city’s most valuable and celebrated resources: the Royal Nairobi Golf Club, Ngong Forest and the Nairobi dam.

Google-ing Kibera would not reveal much information about the slum, but more significantly, information also lacked within the slum. In the eyes of the government, the slum did not exist or matter and only few stories, usually about gangs and murders with attention-grabbing sensational headlines bordering sinister hilarity, were deemed newsworthy.

The idea of the smart city is a vision of a networked urbanism. The promise is that environmental monitoring and feedback from embedded sensors everywhere will simultaneously deliver greener and more productive cities.
