Hortas comunitárias e a valorização imobiliária : um estudo de caso em áreas urbanas subutilizadas

Abstract

This research examines the impacts of implementing community gardens on the property value appreciation of residential real estate located in underutilized urban areas, using the city of Caxias do Sul/RS as a case study. The objective was to propose a method to identify the influence of these gardens on housing price dynamics, integrating urban, environmental, and economic variables. A database was built with 1,157 georeferenced residential properties collected from online real estate platforms, including structural and spatial information. The analysis was conducted through multiple regression models and Geographic Information Systems (GIS) techniques, enabling the assessment of the relationship between property attributes, proximity to community gardens, and market values. The results indicated that, in the overall sample, the variable “distance to the garden” was not statistically significant. However, segmented analyses revealed heterogeneous effects: for properties located within 1 km, there was evidence of devaluation in the immediate surroundings of gardens, while at distances greater than 3 km, a positive effect was observed, with property appreciation associated with proximity. These variations demonstrate that contextual factors such as the presence of power transmission lines, lack of sanitation infrastructure, low tree coverage, and absence of sidewalks directly interfere with the outcomes, potentially neutralizing or reversing the expected positive effects. The study contributes theoretically by integrating urban agriculture, hedonic pricing, and spatial analysis, offering a methodological model replicable in different contexts. In practical terms, it provides support for public policies on sustainable urban development by showing that community gardens can serve as instruments of territorial requalification, provided they are implemented in suitable urban environments. It is concluded that the influence of community gardens on property value appreciation is not homogeneous and must be assessed considering multiple social, environmental, and urban dimensions.
