The Indian Express newspaper (link below) reports on a study in Hyderabad, India that identifies the linkages between urban agricultural practices, sewage treatment and reuse, carbon emissions and health. Network member Anu Ramaswami (University of Minnesota), Leslie MiIler-Robbie (University of Colorado, Denver) and Priyanie Amerasinghe (International Water Management Institute) collaborated on this study, recently published in the journal Environmental Research Letters (Link to article). The study finds that sewage treatment along with water reuse in urban agriculture can offer benefits to carbon mitigation and public health, although the public health benefits are less than expected due to farming practices and prior history of sewage-related soil pollution in the region.

Climate change: Untreated sewage major contributor in The New Indian Express

The carbon emission benefits of sewage treatment are large since untreated sewage discharged to rivers converts to methane which is a potent greenhouse gas. Untreated sewage and household waste, along with emissions from burning of petrol and diesel in cars, and coal to provide electricity are among the major contributors to greenhouse gas emissions in cities.
