This chapter discusses the implementation challenges of the WHO Guidelines on safe wastewater use pertaining to the adoption of the so-called ?post-treatment? or ?non-treatment? options, like safer irrigation practices or appropriate vegetablewashing in kitchens. Due to limited risk awareness and...

Facilitating the adoption of food-safety interventions in the street-food sector and on farms
The growing urban demand for food and changing diets are two of the main factors for changing urban food systems in terms of food quantity and diversity, as well as underlying production and distribution systems. In order to meet the urban food needs while minimising negative environmental effect...

Food flow analysis: the role of locality in feeding cities [Abstract only]
Nutrients and virtual water in the form of food and other organic goods are transported from the rural hinterland to urban centres. In particular in developing countries, poor waste management in growing cities and the potential to recover nutrients and water for agricultural production have rais...

Nutrient and virtual water flow analysis for Tamale, Ghana and Ouagadougou, Burkina Faso
This empirical study examines food sources and their quantitative contribution to the city of Tamale, Ghana. The results contribute to an understanding of the urban food system, and evoke questions relating to the standardised measurement and evaluation of urban food system resilience across geog...

Examining food sources in the city of Tamale, Ghana
Recent studies have examined the urban metabolism of cities using urban consumption as a proxy for food inflows but very few studies have aimed at quantifying the role of cities as trade hubs and nutrient sinks of their hinterlands. We therefore examined the linkages between food and animal feed ...

Food- and feed-based nutrient flows in two West African cities
Rapid urban growth in sub-Saharan Africa challenges food supply of cities. As food and other organic matter are transported from production areas to consumption points, water, which has been used for their production, is transported virtually. This study aimed at determining the magnitude and sou...

Virtual water flow in food trade systems of two West African cities
This Atlas summarizes recent advances in interdisciplinary approaches and research to address the different components of West African urban food systems, including urban and peri-urban agriculture. It thereby draws on the results of several major collaborative research projects and stakeholder c...
