Say the word “Outcomes of neighborhood maintenance”
Groenewegen, van den Berg, de Vries & Verheij (2006): Vitamin G (point 1)Kuo0 and Sullivan (2001): Environment and Crime in the Inner City (point 2)Malakoff’s ACGA monograph reviews two unpublished reports, one from Philadelphia (cite) and another from San Francisco (cite) that observed marked reductions in burglaries, thefts and illicit drug dealing in neighborhoods with garden projects. Well maintained green areas promote health and well-being: Reduced mental fatigue, aggression, violence, crimeLower blood pressure and muscle tensionIncrease social cohesion by promoting opportunities for interaction among residents
Explain where this idea came from. Hot spots are highly maintained, blue are poorly maintained areas

Outcomes – make sure note that this is for “well cared for parks and gardens”
Make sure to note that produce gardens also had to be “actively maintained”
Define lawn maintenanceSelect appropriate properties to compare
After controlling for neighborhood level population and social characteristics, we found better lawn maintenance in residential, occupied properties near produce gardens Found the same at 100m.
