空地上往往杂草丛生，到处都是垃圾，成为藏匿非法枪支、贩卖毒品、卖淫等非法活动和从事暴力犯罪的理想场所。有一些证据表明，绿化空地与减少暴力犯罪有关。我们进行了一项空地绿化的随机对照试验，以测试这种干预对警察报告的犯罪和居民对安全和混乱的看法的影响。绿化包括清理土地，种草种树，在周围筑起木栅栏。我们将两个空地集群随机分配到绿化干预和控制状态（不干预）。行政数据用于确定犯罪率，基线（n=29）和随访（n=21）的当地居民访谈用于评估对安全和混乱的看法。未经调整的差异中之差估计显示，与对照组相比，绿化空地周围的总犯罪和枪支袭击数量没有显著减少。居住在干预空地周围的人比居住在对照空地周围的人在绿化后感觉更安全（p<0.01）。在这项研究中，绿化与某些枪支犯罪的减少和居民安全意识的提高有关。需要一个更大的随机对照试验来进一步调查空地绿化和减少暴力之间的联系。
Vacant lots are often overgrown with unwanted vegetation and filled with trash, making them attractive places to hide illegal guns, conduct illegal activities such as drug sales and prostitution, and engage in violent crime. There is some evidence that greening vacant lots is associated with reductions in violent crime. We performed a randomised controlled trial of vacant lot greening to test the impact of this intervention on police reported crime and residents’ perceptions of safety and disorder. Greening consisted of cleaning the lots, planting grass and trees, and building a wooden fence around the perimeter. We randomly allocated two vacant lot clusters to the greening intervention or to the control status (no intervention). Administrative data were used to determine crime rates, and local resident interviews at baseline (n=29) and at follow-up (n=21) were used to assess perceptions of safety and disorder. Unadjusted difference-in-differences estimates showed a non-significant decrease in the number of total crimes and gun assaults around greened vacant lots compared with control. People around the intervention vacant lots reported feeling significantly safer after greening compared with those living around control vacant lots (p<0.01). In this study, greening was associated with reductions in certain gun crimes and improvements in residents’ perceptions of safety. A larger randomised controlled trial is needed to further investigate the link between vacant lot greening and violence reduction.
