Modelación espacial de servicios ecosistémicos urbanos asociados a la cobertura arbórea en tres barrios de la localidad de suba, bogotá (2022–2025)

Abstract

This research aimed to spatially model urban ecosystem services associated with tree cover in the neighborhoods of Compartir, Almendros, and San Andrés, located in the Suba district of Bogotá, during the period 2022–2025. The study was conducted to better understand how the distribution of urban trees influences the provision of environmental benefits in urban areas characterized by high population density and an unequal distribution of green spaces. The methodology followed a quantitative approach supported by Geographic Information Systems (GIS), spatial analysis, and the processing of information obtained from urban tree inventories, official cartography, and multitemporal satellite imagery. Variables such as species, diameter at breast height (DBH), tree height, and canopy cover were integrated and complemented through spatial validation and fieldwork activities. ArcGIS Pro and i-Tree Eco were used to model and analyze the selected ecosystem services, focusing on carbon sequestration, shade provision, and biodiversity support potential. The results revealed significant variations in tree cover and in the capacity to provide these ecosystem services, allowing the identification of areas with greater environmental benefits as well as sectors requiring urban forestry strengthening strategies. Finally, the study proposed urban environmental management guidelines aimed at the conservation, maintenance, and enhancement of tree cover as a tool to improve environmental quality, promote urban resilience to climate change, and contribute to a more equitable distribution of ecosystem service benefits across the territory.
