Determinación de la salud ecosistémica del humedal El Resbalón con base en la identificación de los servicios ecosistémicos

Abstract

This project was based on the determination of the ecosystemic health in the wetland El Resbalón situated in the village of Cota, Cundinamarca; due to its identification of the ecosystemic services, through the implementation of the methodology of Odum’s symbols, which allowed to represent graphically the relations among the ecosystem variables and the dynamics of the elements that form a structural and functional part of the wetland by means of diagrams, through the model of white box (structure) and black box (function), those represent the inputs and outputs of matter, energy and data in the system. To the development of this project, first of all a documentary revision of secondary information was made, then we made an exploration trip to the wetland, which lets a first approach and the identification of the ecosystemic services by means of field format based on Millenium Ecosystem Assessment (MEA); Afterwards it is the experimental design stage, where it was established the white box and black box model. Lastly in this stage, it was determined the ecosystemic health of the wetland El Resbalón since the supply and demand of the ecosystem goods and services through indicators such as irrigation water use index (IWUI), service offering (SO) and the British Columbia water quality index (BCWQI), altogether with the analysis of the potential value of the ecosystemic services, it was claimed that wetland El Resbalón is an ecosystem which provides a big amount of services, and despite the diverse environmental tensors like the domestic, livestock and agricultural dumping, it is in an intermediate level of affectation or disruption of the ecosystemic stability.
