Effects of greening and community reuse of vacant lots on crime

Urban Farm DB summary

Using a difference-in-differences design, this study evaluates Youngstown's 'Lots of Green' program, comparing crime around newly treated vacant lots—via a cleaning-and-greening 'stabilization' treatment and a 'community reuse' treatment involving mostly community gardens—to matched untreated control lots. It finds statistically significant reductions across crime classes for at least one treatment type, with community-initiated greening associated with greater reductions in serious, violent crimes, alongside spillover reductions in contiguous areas but increases in motor vehicle thefts.
