Equitable access to greenspace should be viewed as a necessity for sustainable and inclusive cities, said Kathryn Schertz, a fourth-year doctoral student at ENL, during an interview with the department of psychology at the University of Chicago. In her recent research published in NPJ Urban Sustainability, local street activity and park visits were found negatively associated with crime. DAG models were used to explore the direct and indirect relationship between these observable variables extracted from cell phone trace data. Which opened a door for future causal studies in the lab.
