Map Kibera: Nairobi youth map their own slum onto OpenStreetMap (2009)

Kibera, a Nairobi settlement that UN-Habitat estimated at 500,000–700,000 people and home to more than 100 NGOs, had never been mapped; its clinics, water points, schools and crime spots were invisible to outsiders and often to residents themselves, while data that NGOs collected stayed locked in reports.

Train Kibera's own youth to survey their settlement with GPS and publish whatever matters to them — clinics, water, schools, security — as free, open map data.

In November 2009 twelve youths took a two-day GIS workshop, then walked Kibera's villages with GPS units, recording roads, water and health facilities, schools, churches, mosques, businesses and NGO offices. Everything was uploaded as free, editable data to OpenStreetMap, and the team later added SMS, blog and video reporting under the name Voice of Kibera.

Kibera became visible on open maps for the first time, with data anyone could read or extend; in 2014 the project earned a special mention at the City to City Barcelona FAD Awards, and write-ups credit it with turning residents' needs — an extra police post, repaired public toilets — into demands officials could see.

Kibera, Nairobi's largest informal settlement, sat as a blank space on every public map well into 2009. UN-Habitat estimated its population at 500,000 to 700,000, and more than a hundred NGOs worked there — yet its water points, health clinics, schools and security problems were invisible to the outside world and, as project founders put it, often to residents themselves.

The idea behind Map Kibera was to invert the usual direction of expertise. Instead of outside surveyors, twelve local youths took a two-day geographic information systems workshop and then walked the settlement's villages with GPS devices, mapping the roads and the services that mattered: clinics, water sources, schools, churches and mosques, businesses, and the offices of organisations working in the area.

The resulting data was published as free, open, editable map data on OpenStreetMap rather than filed away in NGO reports. The point, said co-founder Mikel Maron at the time, was accountability: with shared information it would be clear which organisations actually worked in Kibera, and planning could be based on where health centres and other facilities really were — and what was missing.

The map grew into Voice of Kibera, a community platform that added SMS reporting, blogs and video. In 2014 the initiative received a special mention at the City to City Barcelona FAD Awards, which praised the young residents who produced the first free digital map of their own locality in 2009.

The project inverted expertise: it trained young residents who knew the settlement instead of importing outside surveyors, so the map's priorities came from inside Kibera.

Data was published as free, open and editable information rather than locked in reports, making clinics, water points and roads a shared resource for residents, agencies and government alike.

The mapping brief was everyday life — health, water, schools, security, businesses — the services people actually need, not donor categories.

Adding SMS, blogs and video turned a static map into a two-way reporting channel, letting the community keep the data alive and broadcast what mattered to them.

Cheap GPS tools and open-source software made the method light enough that its backers planned the same approach for Nairobi's Mathare and Mukuru settlements.

Let residents map themselves and they decide what is visible: an open, community-drawn map turns a 'blank spot' into a place officials and NGOs can finally act on.

Map Kibera grew from a one-off map into Voice of Kibera, where residents added SMS reports, blogs and video that kept the data current as local news. Press accounts credit the project with focusing official attention on concrete needs, from an additional police post to rehabilitating public toilets, and its backers planned the same model for Nairobi's Mathare and Mukuru settlements. In 2014 the initiative received a special mention at the City to City Barcelona FAD Awards, and it is widely cited as an early proof that participatory mapping can make an informal settlement legible to planners.
