Kibera Urban Slum, Nairobi, Kenya

Infrastructure
The Uganda Railway Line passes through the centre of the neighbourhood, providing passengers aboard the train a firsthand view of the slum. Kibera has a railway station, but most residents use buses and matatus to reach the city centre; carjacking, irresponsible driving, and poor traffic law enforcement are chronic issues.
Kibera is heavily polluted by human refuse, garbage, soot, dust, and other wastes. The slum is contaminated with human and animal faeces, due to the open sewage system and the frequent use of "flying toilets". The lack of sanitation combined with poor nutrition among residents accounts for many illnesses and diseases. The Umande Trust, a local NGO, is building communal toilets that generate methane gas (biogas) for local residents.
