The Millennium Development Goal (MDG) target of halving the proportion of the population without sustainable access to basic sanitation by 2015 is still very far from being
achieved. Much remains to be done particularly in Africa and Asia. Availability, accessibility, functionality, and correct ...
Material flow analysis was applied to model different scenarios which help better identify and quantify water supply and wastewater pollution problems in the city of Kumasi, Ghana. Results show that despite a relative abundance of water resources in the surrounding area of the city, drinking wate...

This study investigates helminth eggs removal and inactivation efficiency in a treatment process combining faecal sludge (FS) dewatering and subsequent co-composting with organic solid waste as a function of windrow turning frequency. Fresh public toilet sludge and septage mixed at a 1:2 ratio we...

We developed a conceptual framework for improving health and environmental sanitation using an approach that combines health, ecological, and socio-economic assessments. The framework has three main components: health status, physical environment,
and socio-economic environment. Information on ...

Interdisciplinary research on environmental sanitation and health: Conceptual framework development and field test
Poor wastewater management that results from a lack of appropriate sanitation infrastructure contributes to increasing health risks in urban areas in Côte d’Ivoire. We assessed the health risks associated with the use of wastewater for watering salad destined for human consumption, to help local ...

Human excreta are rich in plant nutrients, so many farmers in Vietnam use them to fertilize their crops and in raising fish. But they also contain dangerous pathogens: bacteria, viruses, protozoa, and the eggs of intestinal parasites. Exposure can pose a health risk to farmers, their families, as...
