A new study by a Temple research team shows that the presence of vegetation in urban settings may reduce crime. The Temple researchers, led by Jeremy Mennis of the Department of Geography and Urban Studies and environmental studies major Mary Wolfe, looked at crime rates and satellite imagery in Philadelphia and found that areas with well-maintained landscaping have lower rates of aggravated assault, robbery and burglary. The authors believe well-maintained green areas encourage social interaction and community pride and may also reduce psychological precursors to violent acts.
