The objective of this research is to understand the dynamic relationship between wastewater used for irrigation and food safety in terms of a) production and processing of food with wastewater; b) inputs to food production such as fertilizers and pesticides, and soil; and c) consumption of food produced using wastewater for irrigation, which will have adverse effect on health and nutrition.

The specific objectives are:

• to understand the demand for safe food in urban and peri-urban areas where wastewater is used uncontrollably for irrigating agricultural crops;
• to estimate the consumers’ willingness to pay a price premium for ensuring good quality and safe food and water;
• to use a risk assessment to demonstrate the base line risk associated with using wastewater for food production;
• to identify cost-effective control measures for reducing risks associated with use of wastewater for irrigation; and
• to communicate these findings to consumers and decision makers
