This dissertation presents a methodology of short-cutting the phosphorus cycle in urban ecosystems.  In nature, the P-cycle is a circular, closed-loop system, but human activities use and dispose P in a linear, open-ended system leading to the customary environmental problems.  Lake Chivero in Zimbabwe is used as a case study to illustrate the unsustainable practice of discharging valuable and finite phosphorous into drinking water resources.  Short-cutting or closing the P-cycle in the urban environment is closely related to the closure of water cycles.  Closing the P-cycle is dependent on the adoption of ecological sanitation and eco-city concepts.  These concepts lead to solutions, which are source orientated (local and small scale), non-mixing, ecologically sound, closed-loop systems.  Recycling of P in urban ecological agriculture (without synthetic fertilisers) is used in this dissertation to test the feasibility of these concepts. A phosphorus calculator has been developed, based on studies of monthly P-fluxes and stocks, in a high-density suburb of Harare in Zimbabwe, where agriculture is an established activity.
