| Abstract:
Environmental sanitation comprises disposal and treatment of human excreta, solid waste and wastewater, control of disease vectors, and provision of washing facilities for personal and domestic hygiene. The conventional approach to environmental sanitation is characterised by a linear waste management system, where valuable plant nutrients are often not only wasted, but also create pollution problems in receiving waters. Closing the nutrient loop is one of the main objectives of a more ecological approach to environmental sanitation. Reuse of wastewater and organic waste in urban agriculture may contribute to closing this nutrient loop. In addition to food security and income generation, urban agricultural activities can thus help to improve public health and resource management. However, some urban agricultural processes, such as “agricultural practices”, “soil quality management” and “irrigation”, still requires further research. | |
