Análisis Mediante Sistemas de Información Geográfica de los Impactos Ambientales Generados por la Ampliación de la Avenida Boyacá Entre las Calles 183 y 235 en la Reserva Forestal Regional Productora del Norte de Bogotá D.C., Thomas Van Der Hammen.

Abstract

The expansion of Boyacá Avenue between 183rd and 235th streets in Bogotá D.C. involves the removal of 20.87 hectares from the "Thomas Van der Hammen" Regional Forest Producer Reserve of the North (RFTvdH), a key ecosystem for the ecological connectivity of the city. This study used Geographic Information Systems (GIS) to analyze the environmental impacts of this intervention. The diagnosis of the biotic environment showed the fragmentation of habitats and the reduction of biodiversity. In the abiotic environment, alterations in soil quality, the water regime and the local climate were identified. In the socioeconomic environment, the project would modify urban dynamics and access to environmental services in the surrounding neighborhoods. The impact assessment, using the Conesa methodology, revealed that 45% of the impacts were critical, highlighting the affectation of biological corridors and hydrological alteration. 30% were relevant, mainly in terms of air and soil quality, while 20% were moderate, associated with the loss of vegetation cover and pressure on ecosystem services. Only 5% were of low importance. The results underline the need for mitigation and ecological restoration strategies that reduce territorial fragmentation and promote sustainable urban planning. It is concluded that the lack of design alternatives is evidence of inadequate management of land use. These studies are key to land management, as they provide technical tools that balance urban development with environmental conservation.
