Crime and Greenspace: Extending the Analysis Across Cities

The role of greenspace in urban areas has become a focus of research as municipalities seek to increase the quality of life in cities. Multiple benefits are found to be associated with greenspace, but disservices such as crime are often overlooked. Studies investigating the link between crime and greenspace have revealed mixed results and been limited in geographic scope. This dissertation sought to examine the crime and greenspace relationship, extending the analysis to multiple cities in order to describe how the relationship may vary in different contexts. Additionally, one possible cause of crime, increased temperatures, was investigated to determine how greenspace may moderate the impact of hot weather on crime risk. As urban parks are an important type of greenspace, the relationship between proximity to parks and crime was examined in four case cities. Parks are typically green areas of cities but also encompass less green land uses. This broad analysis revealed a more comprehensive understanding of how crime and greenspace are related which can inform residents and decision-makers of the benefits and possible drawbacks from including greenspace in city and community development

A framework for mapping cultural resources in landscape conservation planning

Abstract Cultural resources can be an important means of connecting people to conservation efforts. Currently, it is difficult to identify and map these tangible and intangible aspects of the landscape. We propose a framework to include cultural resources in spatial conservation planning that acknowledges the different scales of importance and management of sites. Through categorizing and mapping sites of national, state, local, interest group, and community management, cultural resources can be measured and included in existing planning tools. Data on cultural resources are a primary limitation due to availability and fragmentation. Until data sources improve, our framework provides a stopgap that allows for cultural resources to be included in conservation‐planning efforts

Effects of Crime Type and Location on Park Use Behavior

Crime and the fear of crime can be a barrier to park use, and locations of crimes can have varied effects. Unsafe areas in or around the park, around the residence, or along the route to the park can alter park use behavior. Our study aimed to examine associations between objective measures of types and location of crimes and park use behaviors. In 2013 we surveyed a sample (N = 230) of residents in Greensboro, North Carolina, about park use, with responses matched to objective crime and spatial measures. We measured all crimes and violent crimes near home, near the closest park, and along the shortest route between home and park. By using ordered and binary logistic modeling, we examined the relationships between the locations of crime and park use and duration of park visit, park rating, and never visiting parks. Additional models included distance to the closest park. Increased crime in parks and near home was associated with fewer park visits. Greater violent crime in all locations was related to fewer park visits. Park ratings were lower for parks with high violent crime rates. Given the importance of parks as settings for outdoor recreation and physical activity, crime may have a detrimental effect on physical activity and, therefore, public health

Associations of parks, greenness, and blue space with cardiovascular and respiratory disease hospitalization in the US Medicare cohort

Natural environments have been linked to decreased risk of cardiovascular disease (CVD) and respiratory disease (RSD) mortality. However, few cohort studies have looked at associations of natural environments with CVD or RSD hospitalization. The aim of this study was to evaluate these associations in a cohort of U.S. Medicare beneficiaries (∼63 million individuals). Our open cohort included all fee-for-service Medicare beneficiaries (2000-2016), aged ≥65, living in the contiguous U.S. We assessed zip code-level park cover based on the United States Geological Survey Protected Areas Database, average greenness (Normalized Difference Vegetation Index, NDVI), and percent blue space cover based on Landsat satellite images. Cox-equivalent Poisson models were used to estimate associations of the exposures with first CVD and RSD hospitalization in the full cohort and among those living in urban zip codes (≥1000 persons/mile2). NDVI was weakly negatively correlated with percent park cover (Spearman ρ = -0.23) and not correlated with percent blue space (Spearman ρ = 0.00). After adjustment for potential confounders, percent park cover was not associated with CVD or RSD hospitalization in the full or urban population. An IQR (0.27) increase in NDVI was negatively associated with CVD (HR: 0.97, 95%CI: 0.96, 0.97), but not with RSD hospitalization (HR: 0.99, 95%CI: 0.98, 1.00). In urban zip codes, an IQR increase in NDVI was positively associated with RSD hospitalization (HR: 1.02, 95%CI: 1.00, 1.03). In stratified analyses, percent park cover was negatively associated with CVD and RSD hospitalization for Medicaid eligible individuals and individuals living in low socioeconomic status neighborhoods in the urban population. We observed no associations of percent blue space cover with CVD or RSD hospitalization. This study suggests that natural environments may benefit cardiorespiratory health; however, benefits may be limited to certain contexts and certain health outcomes
