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

空地如果无人看管，就会成为社区的负担，导致犯罪和暴力， 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和 伤害，包括袭击、抢劫和杀人。越来越多的证据表明，补救和 改善空地是减少暴力犯罪和枪支袭击的一个有希望的战略。研究人员已经 还表明，社区参与改善空置地块的努力可能是 持续努力，改善减少暴力的成果。然而，研究人员检查了一种相对狭窄的 一系列绿化战略，包括简单的地块补救(例如，清除垃圾和杂物)和安装 小规模的地块处理(例如，植树、安装分体栏杆)，基本上没有探索 让居民参与这一进程的效果。此外，对于这些努力是如何进行的，缺乏研究 随着时间的推移，持续激活是否会带来额外好处。这项研究的目的是 将调查印第安纳州印第安纳波利斯空地再利用项目现场附近发生的犯罪事件 以社区为基础的组织已将空地用于生产目的。与Keep合作 印第安纳波利斯美丽，我们将检查城市中的120个项目地点，从开始到长达5年 干预后。我们将检验这一假设，即空置土地再利用是预防 并比较空地再利用对暴力事件和伤害的影响，相对于一组 没有重复使用的比较站点(N=240)。我们还将研究社区水平如何 参与可以通过严格的现场记录和加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网站的案例研究，减少了暴力 意外事件。我们建议进行研究的具体目的是：1)研究空置土地的短期影响 关于总体暴力犯罪事件和伤害以及社区参与程度如何改变的再利用项目 影响；2)检查空地再利用项目对暴力犯罪事件总数和伤害的长期影响 以及社区参与程度如何改变效果；以及3)深入开展 12个空地再利用场地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.
