Can cleaning vacant lots cause a chain of events that curbs child abuse or stops a teen from falling victim to violence? That’s the provocative question behind a new research project to study whether maintaining vacant lots and fixing up blighted properties in high-crime areas reduces incidents of youth and family violence. The National Institutes of Health awarded Tulane a $2.3 million grant to test the theory in New Orleans. Katherine Theall, Cecile Usdin Professor in Women’s Health in the School of Public Health and Tropical Medicine, is the principal investigator.
