Vacant Lot Greening and Violence-Related Outcomes

Overview

The purpose of this study is to determine the impact of vacant lot greening on perceptions of safety and violence for residents living around the lots. We hypothesize that people living around lots that are greened will have improved perception of safety.

Violence is a serious health problem in the US, and especially in Philadelphia, as the city ranks first in violent crime amongst the ten largest US cities. The determinants of violent crime range from individual to community level factors. In this study, we focus on physical incivilities in the built environment, specifically vacant lots, as they have been associated with violent crime. Physical incivilities are also associated with individual perceptions of crime and safety, and subsequently, negative health outcomes. However, prior research has been observational and retrospective. We aim to expand this body of work through a randomized community intervention trial of vacant lot greening to explore causal mechanisms between vacant lots and violent crime outcomes. This pilot study, in partnership with the Pennsylvania Horticultural Society, will investigate the feasibility of a vacant lot greening intervention, and explore how vacant lot greening changes resident perception about violence, fear, stress, and neighborhood disorder, as well as violent crime in the surrounding area. We will interview residents living around the greened and non-greened lots during a joint walk around a pre-determined route, which will ensure exposure to our intervention. We will also use violent crime data (homicide, aggravated assault, robbery, and rape) from the Philadelphia Police Department. Results of this pilot trial will be used to develop a full scale vacant lot greening grant to be submitted to the National Institutes of Health or the National Institute of Justice.
