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.\u003c\/p\u003e","brand":"Taylor \u0026 Francis","offers":[{"title":"Hardcover","offer_id":45238284648599,"sku":"9781138424418","price":11621.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9781138424418.webp?v=1769219281","url":"https:\/\/atlanticbooks.com\/products\/short-cutting-the-phosphorus-cycle-in-urban-ecosystems-9781138424418","provider":"Atlantic Books","version":"1.0","type":"link"}
