Evaluación Económica Ambiental del Proyecto Ciudad Paz en la Reserva Thomas Van Der Hammen con Relación a la Infraestructura Vial

Abstract

The reserve Thomas Van der Hammen can be considered as the lung of Bogota; however, it is going to be intervened in order to carry out the construction of the Ciudad Paz project, for which a series of pathways have been designed and they will cross this ecosystem. This research was framed under the main objective of evaluating economically and environmentally the Ciudad Paz project in the Thomas Van der Hammen Reserve in relation to the road infrastructure, by conducting studies such as the Rapid Ecological Assessment (EER) to have a physiobiobiotic diagnosis And socioeconomic status of the current state of the reserve, an environmental impact assessment through the implementation of the Matrix matrix developed by Vicente Conesa Fernández (1997) and the ANLA (National Environmental Licensing Authority) guidelines published in 2010.In this study, secondary information was used mainly generated by the Environmental Management Plan of the Regional Forestry Reserve of North Bogota D.C. "Thomas van der Hammen" developed by the Regional Autonomous Corporation (CAR), taking relevant information on the biotic, abiotic and social environment of the reserve. The methodological development consisted of the identification and evaluation of the Environmental impacts for the scenario with and without project; Prioritization and qualification of environmental impacts; Then the physical quantification of the most relevant impacts was performed with a monetary value, in which the flow of benefits and costs is deducted, and finally the economic viability of the project is determined. The results obtained from the rapid ecological assessment show that the vicinity of the Thomas Van der Hammen Reserve are habitats of great diversity of species both in fauna and flora and that the wetland the Conejera is one of the ecosystems of greater value Environmental for Bogotá, since it offers a system of regulation in the level of pollution that the city generates. With regard to economic valuation, it is determined that the aforementioned project is not viable, since there is a higher level of negative impacts, such as loss of species and vegetation cover, vehicular traffic that will affect air quality, solid waste generation, among others. As for the cost-benefit ratio, the four roads had a relation cost- profit below 1, which indicates that the project in relation to the road infrastructure is not profitable. That is to say, what is planned to be built implies such high environmental and economic costs that will not be compensated with the great affectation that would occur if this reserve is intervened.
