Growing change: a GIS spatial analysis to plan urban gardens in Chattanooga

Food insecurity and limited access to fresh nutritious food in Chattanooga is a prevalent issue, primarily among lower socioeconomic households, and can put strain on overall well-being. This study aimed to identify suitable vacant parcels in Chattanooga where urban gardens could be developed using a GIS-based spatial analysis. Spatial data involving vacant parcels, slope, zoning, and proximity to grocery stores was cross referenced with socioeconomic data focused on poverty rates, vehicle ownership, and mean household income to identify the most suitable sites in areas of greatest need. Sites identified as suitable through GIS were then visited to verify their suitability. Of all the sites included in the composite index, 31 potential sites were identified through the spatial analysis, of which 16 (51.6%) were found to be viable after field verification. The results suggest that urban garden implementation at verified sites could help improve food access and support overall well-being within communities.
