[en] Public green spaces (PGS) are considered fundamental elements in the sustainable city model, competing various environmental, ecosystemic, and social roles. The quality and accessibility are key factors in maximizing their positive effects on human health. This study was conducted in the city of Concepción del Uruguay, Argentina, with the aim of describing the situation of PGS in terms of their distribution, size, and analyzing their spatial accessibility using a quantitative descriptive approach. Firstly, public green spaces within the city were identified and classified using satellite imagery and field visits. The coverage of public green spaces was then quantified at a global level and stratified according to census areas. A proximity analysis was performed using different access distances to PGS according to their size, and the population with simultaneous coverage of three types of green spaces was calculated. Subsequently, differences in the surface area of green spaces were evaluated based on the unsatisfied basic needs of households in each census area using statistical tests. Finally, the spatial distribution pattern of green spaces was analyzed using spatial autocorrelation, and statistical tests were conducted to assess the existence of significant spatial clusters. 34 % (24,928 inhabitants) of the population have simultaneous coverage of three types of green spaces. There is no significant association between the size or quantity of PGS and the percentage of households with Unsatisfied Basic Needs according to census tracts (p &lt;0.01). The results can be useful for the planning and management of these spaces, as well as for addressing challenges related to spatial equity and urban sustainability.

[es] Los espacios verdes públicos (EVP) son elementos fundamentales en el modelo de ciudad sustentable, desempeñando diversas funciones ambientales, ecosistémicas y sociales. Su calidad y accesibilidad son factores clave para maximizar sus efectos positivos en la salud humana. El presente estudio se realizó en la ciudad de Concepción del Uruguay, Argentina, con el objetivo de describir la situación de los EVP en relación a su distribución, dimensión y accesibilidad espacial, mediante un enfoque descriptivo cuantitativo. Primero, se identificaron y clasificaron los EVP a partir de imágenes satelitales y salidas de campo. Luego se cuantificó la cobertura a nivel global, estratificando según radios censales. Se realizó un análisis de proximidad utilizando diferentes distancias de acceso a los EVP según tamaño y se calculó la población con cobertura simultánea de tres de ellos. Posteriormente, se evaluaron las diferencias en la superficie de los espacios verdes según las Necesidades Básicas Insatisfechas (NBI) de los hogares en cada área censal mediante pruebas estadísticas. Finalmente, se analizó el patrón de distribución espacial de los EVP mediante autocorrelación espacial y se realizaron pruebas estadísticas para evaluar la existencia de agrupamientos espaciales significativos. El 34 % (24 928 habitantes) de la población cuenta con cobertura simultánea a tres tipos de EVP. No existe una asociación significativa entre el tamaño, ni la cantidad de los EVP con el porcentaje de hogares con NBI según radio censal (p &lt;0,01). Los resultados pueden ser útiles para la planificación y gestión de estos espacios, así como para abordar desafíos relacionados con la equidad espacial y la sustentabilidad urbana.
