Wastewater often used in urban agriculture: study
Wastewater is widely used to irrigate urban agricultural land in developing countries, a practice that has both advantages and disadvantages, a 53-city study presented at a water conference in Stockholm showed Monday. Wastewater agriculture contributes importantly to urban food supplies and helps provide a livelihood for the poor, but can also lead to health risks for consumers, particularly for vegetables consumed uncooked, the report by the International Water Management Institute (IWMI) said.
