Kibera Public Space Project (KPSP) is a network of public spaces that sustainably transforms communities in Africa's largest slum. Residents have taught us that housing alone isn't enough. To truly improve quality of life projects must equally plan for the environmental, social & economic sustainability of a community. This understanding led to the concept of Productive Public Space-waste spaces like dumps rebuilt through a community-driven process to mitigate environmental hazards, provide amenities & develop enterprises that fund site maintenance. Our 1st site includes a garden, public hall, playground & water. The sales of fertilizer made from community compost & baskets woven from a native plant provide ongoing financial support. Our 2nd site also has showers, toilets & a school.
