Drechsel, PayKarg, H.Appoh, Richard K.Akoto-Danso, Edmund K.[Resilience of urban food supply in West Africa]Resilience of urban food supply in West Africa

In response to changing urban food systems, short supply chains have been advocated to meet urban food needs while building more sustainable urban food systems. Despite an increasing interest in urban food supply and the flows of food from production to consumption, there is a lack of empirical s...


Karg, H.Drechsel, PayAkoto-Danso, Edmund K.Glaser, R.Nyarko, G.Buerkert, Andreas[Foodsheds and city region food systems in two West African cities]Foodsheds and city region food systems in two West African cities

Where wastewater is used without appropriate treatment, additional safety measures such as safer irrigation practices or careful vegetable washing are required to protect farmers and consumers. Implementing such food safety interventions in the informal farming sector is not easy, as they require...


Drechsel, PayKarg, H.[Motivating behaviour change for safe wastewater irrigation in urban and peri-urban Ghana]Motivating behaviour change for safe wastewater irrigation in urban and peri-urban Ghana

The increased emphasis on non- or post-treatment measures in the 2006 edition of the World Health Organization Guidelines on the safe use of wastewater in agriculture will require behaviour change along the food chain. Low health risk awareness likely limits adoption of safe food practices in man...


Karg, H.Drechsel, Pay[Motivating behaviour change to reduce pathogenic risk where unsafe water is used for irrigation]Motivating behaviour change to reduce pathogenic risk where unsafe water is used for irrigation

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...


Karg, H.Akoto-Danso, Edmund K.Drechsel, Pay[Examining food sources in the city of Tamale, Ghana]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 ...


Karg, H.Akoto-Danso, Edmund K.Drechsel, PayAbubakari, A.-H.Buerkert, Andreas[Food- and feed-based nutrient flows in two West African cities]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...
