This volume addresses the issue of urban wastewater in agriculture, which is an age-old practice that is receiving renewed attention due to the increasing scarcity of fresh water resources. This practice is vastly un-regulated in poor countries, and the health and environmental costs and benefits are often unknown or unacknowledged. Existing options to treat wastewater is expensive and some countries do not possess the financial means to execute these methods. This is a useful publication to those interested in hydrology, soil science, agricultural engineering, development economics, public health, development studies, urban and peri-urban agriculture, and water resource policies.
