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.

This summer, the Sustainable Healthy Cities network at the University of Minnesota hosted two undergraduate students through the Research Experience for Undergraduates (REU) program. Maria Camila Merino Franco (University of Minnesota, Twin Cities) and Morgan Shultz (Salish Kootenai College, Pablo, MT) worked alongside SRN researchers at the University of Minnesota, in collaboration with the University of Michigan, to map urban agriculture practices in St. Paul, Minnesota.  This project mapped various types of urban agriculture through a combined method of GoogleEarth digitizing and field searches. The objective of the work was to assess the current level of urban agriculture in St. Paul and variation across neighborhoods with differing socio-demographic characteristics. “Having Camila and Morgan on board served several goals of our SRN, not only providing useful data and analysis, but giving us additional perspectives and insights about how to move the project forward.  In addition, they were terrific people to work with, and we hope the experience will be valuable to them as they continue to develop and pursue their future careers!” said Frank Douma, coordinator of the network’s participation within the REU program.

Camila is a student at the University of Minnesota Twin Cities studying Biosystems and Bioproducts Engineering with an emphasis in Ecological and Environmental Engineering. Morgan is completing his first year at Salish Kootenai College, a Tribal college in Montana, where he majors in Hydrology. The purpose of the REU program on Sustainable Land and Water Resources is to introduce undergraduate students to key elements of research on land and water resources that are essential to improving management practices, with a focus on Community-Based Participatory Research (CBPR) and diverse interdisciplinary research teams.

Student Feature: Ecosystem Services of Urban Farms by Xinyu Liu and Varsha Gopalakrishnan

April 11, 2017

Xinyu Liu and Varsha Gopalakrishnan, PhD students in Prof. Bhavik Bakshi’s group at The Ohio State University work on integrating the role of ecosystem services into engineering design and decision making. Their work is motivated by the thinking that all engineered products and processes can be economically viable while respecting ecological limits. They use concepts from the fields such as Process Systems Engineering, Life Cycle Assessment, and Ecological Modeling to expand the boundary of traditional engineering methods to include ecosystems and to design systems that operate within nature’s carrying capacity. Ultimately, this research work aims to develop synergies between technological and ecological systems to meet human needs while ensuring sustainability and resilience.

The scale of problems they address varies spatially and temporally, across individual equipment to the life cycle and across technologies and ecosystems. Some of the problems they have focused on include designing integrated networks of technological and ecological systems for industrial plants, developing a theoretical framework to account for ecosystem services in life cycle assessment and life cycle evaluation of several emerging technologies.

As a part of the SRN project, Xinyu and Varsha are interested in understanding the ecosystem services and disservices from different forms of urban farming across multiple cities in the world. Farming activities are associated with a bundle of ecosystem services, such as food provisioning, carbon sequestration and water quality regulation. Considering multiple services simultaneously will prevent the impact shifting to other services, thus enabling more informative decision making. They are interested in analyzing multiple scenarios to understand the benefits of investing in green infrastructure like community gardens and urban farms. This work contributes to the integrated SRN framework by providing quantitative indicators to assess environmental sustainability and linking it to human well-being and livability.
