CE-22-005 Community violence prevention through community-engaged vacant property reuse: Longitudinal application of Busy Streets Theory in Indianapolis

空置的土地，如果不加以管理，就会成为社区的负担，造成犯罪和暴力的后果， 包括枪支暴力。在许多城市中心，高空置率导致暴力发生率上升， 伤害，包括袭击，抢劫和杀人。越来越多的证据表明， 改善空置土地是减少暴力犯罪和火器袭击的一项有希望的战略。研究人员 还表明，社区参与改善空地的努力可能是一个关键组成部分， 持续努力并改善减少暴力成果。然而，研究人员已经研究了一个相对狭窄的 一系列绿化策略，包括简单的地段整治（例如，清除垃圾和碎屑）和安装 小规模批量处理（例如，种植树木，安装分裂围栏），并在很大程度上没有探索 在这个过程中，居民参与的效果。此外，缺乏关于这些努力如何发挥作用的研究。 持续时间以及持续激活是否提供额外的益处。本研究的目的将 调查发生在印第安纳州印第安纳波利斯空地再利用项目现场附近的犯罪事件， 社区组织已将空地用于生产目的。与Keep合作 美丽的印第安纳波利斯，我们将检查整个城市的120个项目，从一开始到最多5年 干预后。我们将检验这样一个假设，即空地再利用是防止土地退化的有效策略。 暴力，并比较空置土地再利用对暴力事件和伤害的影响，随着时间的推移，相对于一组 比较研究中心（N = 240），其中没有重复使用发生。我们还将研究社区的水平如何 通过严格的现场记录，参与可能会增强空地再利用对暴力的影响， 跟踪，以及成功的社区参与项目现场的案例研究，减少暴力， 事故。本研究的具体目的是：1）研究空置土地的短期效应 关于暴力犯罪事件和伤害总数以及社区参与程度如何改变的再利用项目 2）研究空置土地再利用项目对暴力犯罪事件和伤害总数的长期影响 在短期内，以及社区参与程度如何影响效果;以及3）深入开展 12个空置土地再利用地点的案例研究及其对暴力犯罪结果和社区的影响 参与确定有效重用的促进因素和障碍。

Vacant lots, when left untended, become liabilities for communities with consequences for crime and violence, including firearm violence. In many urban centers, high vacancies contribute to increased rates of violence and injury, including assaults, robbery, and homicide. A growing body of evidence suggests that remediating and improving vacant lots is a promising strategy to reduce violent crime and firearm assaults. Researchers have also shown that community engagement in efforts to improve vacant lots may be a critical component to sustain efforts and improve violence reduction outcomes. Yet, researchers have examined a relatively narrow range of greening strategies including simple lot remediation (e.g., removing trash & debris) and installation of small-scale lot treatments (e.g., planting trees, installing split rail fencing), and have largely not explored the effect of engaging residents in this process. Further, there is a lack of research on how these efforts are sustained over time and whether continued activation provides additional benefit. The purpose of this study will be to examine crime incidents occurring near vacant lot reuse project sites in Indianapolis, Indiana, where community-based organizations have reclaimed vacant lots for productive purposes. In partnership with Keep Indianapolis Beautiful, we will examine 120 project sites across the city from their inception to up to 5 years post intervention. We will test the hypothesis that vacant lot reuse is an effective strategy for prevention of violence and compare the effects of vacant lot reuse on violent incidents and injury over time relative to a set of comparison sites (N = 240) where no reuse occurs. We will also examine how the level of community engagement may enhance the effects of vacant lot reuse on violence through rigorous site documentation and tracking, as well as case studies of successful community engaged project sites with a reduction in violent incidents. Our specific aims for the proposed research are to: 1) Examine the short term effect of vacant lot reuse projects on total violent crime incidents and injury and how the level of community engagement modifies the effect; 2) Examine the long term effect of vacant lot reuse projects on total violent crime incidents and injury in the short term and how the level of community engagement modifies the effect; and 3) Conduct in-depth case studies of 12 vacant lot reuse sites and their effect on violent crime outcomes and community engagement to identify facilitating factors and barriers to effective reuse.
