MONTOYA-ROJAS, Grace Andrea  e  RIVERA-MARROQUIN, Michael Esteban. The environmental components of the torca basin: an input for the analysis of climate variability scenarios in Bogotá city, Colombia. rev.udcaactual.divulg.cient. [online]. 2021, vol.24, n.1, e1833.  Epub 21-Abr-2021. ISSN 0123-4226.  https://doi.org/10.31910/rudca.v24.n1.2021.1833.

This review presents a methodology for the spatial analysis of the main interrelationships between the environmental components: atmospheric, geospheric, hydrospheric, biospheric and anthropospheric, and the climatic variability of temperature and precipitation that are projected until the year 2100, in the Torca basin in the city from Bogota, Colombia. The wetlands of the basin are of local, national and international importance, due to the ecosystem services that support flora and fauna. Then, through geographic information systems (GIS), prospective appraisals were established with results already established from 2011 to 2040, from 2041 to 2070 and from 2071 to 2100. Interconnectivity relationships between natural and human systems were identified, to understand the capacities to adapt to variations in temperature and precipitation that are projected in the Basin. One of the most relevant results is associated with the fact that multitemporal prospective analyzes at regional scales need more detail to generate concrete plans of action in strategic ecosystems, such as the wetlands of the Basin. Additionally, the Main Ecological Structure, of which the Torca basin is part, which still fulfills its regulatory functions, but is in danger of degradation due to the rapid growth of the city of Bogotá and the phenomenon of conurbation with neighboring municipalities such as Chía, Sopó and Cajicá, which would decrease their adaptability capacities to the projected climate variability.
