Wastewater reuse in agriculture has several benefits, but can also result in significant health risk if not undertaken in a safe manner as in many developing countries. This work, which began in 2008 in Ghana, is assessing the health risks associated with the reuse of wastewater in agriculture and the cost-effectiveness of interventions for mitigating the health risks. The project was initiated by the WHO and partly funded by the EconSanRes of the Stockholm Environment Institute and the Norwegian Research Council.

Virus mapping and Risk reduction in the Nordic region Advances in water treatment and management practices over the years in the Nordic regions have improved water quality in many regions and reduced the incidence of water-borne disease outbreaks. However, water supply systems are increasingly faced with new challenges linked partly to extreme weather conditions and infrastructure breakdown, poor water catchment management and the emergence of pathogens that compromise water quality and lead to sporadic outbreaks of water-borne diseases in the region. Among different groups of waterborne pathogens, enteric viruses are of major concern. In a newly started, joint Nordic project the main goal is to reduce communities´ vulnerability to virus disease transmission, given potential extreme weather events. In this project, the source, frequency and duration of virus contamination in raw water sources, as well as the efficiencies of drinking water treatment will be monitored to provide inputs for heath risk modeling. The risk modeling will help identify critical control points of virus disease transmission for the development of effective health risk management interventions in water supply systems.
