Economic evaluation of the environmental impacts generated by an emerald mine (municipality of Río Fucha – Bogotá D.C.

Abstract

The connectivity of ecosystems is the key to biodiversity conservation and maintenance of ecological functions, one of the main corridors in the city of Bogotá is the Fucha river basin, which is currently very fragmented, with low Connectivity. In this work, intervention proposals are proposed to increase the connectivity of this system, based on the diagnosis of connectivity between the eastern hills and the Bogotá river, based on studies of vegetal components and the identification of patches by means of satellite images. With the identification of difficulties in establishing ecological corridors, possible solutions were identified to reduce the effects of fragmentation on ecological functioning, green roofs, vertical gardens, tree planting with native species, for the generation of a biological corridor with homogeneous characteristics. It was verified that the connectivity between these zones is quite reduced, mainly due to the degree of fragmentation that is presented, there are few representative patches along the whole river route and none of them present a significant amount of native vegetation, besides This is located at a considerable distance, generating the need to look for alternatives tending to connect them. Through the satellite images obtained, it was observed that the barriers created by urban growth are quite broad, which makes it necessary to intervene on these, using them as base structures for the creation of the ecological corridor through vegetation.
