Shortcutting the Phosphorus Cycle in Urban Ecosystems,Used
Delivery time: 8-12 business days (International)
This dissertation presents a methodology of shortcutting the phosphorus cycle in urban ecosystems. In nature, the Pcycle is a circular, closedloop system, but human activities use and dispose P in a linear, openended 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. Shortcutting or closing the Pcycle in the urban environment is closely related to the closure of water cycles. Closing the Pcycle is dependent on the adoption of ecological sanitation and ecocity concepts. These concepts lead to solutions, which are source orientated (local and small scale), nonmixing, ecologically sound, closedloop 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 Pfluxes and stocks, in a highdensity suburb of Harare in Zimbabwe, where agriculture is an established activity.
