Eco-toilets (human urine and faecal matter collected separately) are one of the best ways to solve sanitation problem, and this practice also improves the environment and increases the food production. This study focuses on experimental demonstration of use of urine, wood ash and poultry dropping...

Urine fertilizer for vegetable production - a case study in Nepal and Ghana.
Irrigation using untreated wastewater poses health risks to farmers and consumers of crop products, especially vegetables. With hardly any wastewater treatment in Ghana, a multiple-barrier approach was adopted and safe re-use practices were developed through action research involving a number of ...

From world cafes to road shows: using a mix of knowledge sharing approaches to improve wastewater use in urban agriculture
Where rapid urbanization is outpacing urban capacities to provide sound sanitation and wastewater treatment, most water sources in city vicinity are heavily polluted. This is of great concern as many of the leafy vegetables eaten raw in the cities are produced in these areas. Following the new WH...

Minimizing health risks and improving system productivity in irrigated urban and peri-urban vegetable farming for enhanced livelihoods
Post-harvest interventions are an important component of a multiple-barrier approach for health-risk reduction of wastewater-irrigated crops as recommended by the 2006 edition of the WHO Guidelines for safe wastewater irrigation. This approach draws on principles of other risk-management approach...
