Zonificación agroecológica de los humedales Santa María del Lago, Torca-Guaymaral y La Conejera, pertenecientes al complejo de humedales urbanos (RAMSAR) de Bogotá.

Abstract

The RAMSAR convention, in conjunction with international cooperation and through local and national actions, has as its mission the conservation and rational use of all wetlands, as a contribution to the objective of sustainable development worldwide. Currently, the Santa María del Lago, La Conejera and Torca-Guaymaral wetlands have an Environmental Management Plan that does not contemplate the main anthropic alterations that have occurred in recent years, for which it is proposed to carry out an agroecological zoning that allows evidence of the use of current soil, environmental stressors and affected ecosystem services and based on this, propose recovery, restoration and conservation strategies for the ecosystems under study. (Ramsar, 2015). Initially, the study variables were identified to generate a baseline, then a series of visits were made to identify these variables, then samples were taken and taken to the laboratory to analyze pH, texture, real density and organic carbon in order to to compare the actual information with the theory and define its current land use. Subsequently, the prioritization method was used to evaluate ecosystem services and formulate recovery strategies, in order to carry out agroecological zoning. Finally, the environmental stressors were identified to propose strategies focused on remedying or minimizing this deterioration. As a result, it was found that the most persistent environmental stressors are discharges due to wrong connections, the presence of invasive species, fragmentation and eutrophication. Regarding the evaluation of ecosystem services, through the proposed methodology, it was found that the most affected are the conservation of soil resources and wastewater treatment. Based on the foregoing, it is concluded that various recovery and conservation alternatives can be implemented, such as promoting the control of invasive species of fauna, encouraging the planting of native species, fencing off the areas where settlements could be located, and identifying discharge points that affect the nature of the environment. wetland, this because the study wetlands have a variety of soil suitable for the sustainable use of resources.
