Apropiación y sensibilización ambiental con la comunidad aledaña al humedal La Conejera, a partir del reconocimiento de los organismos que conforman el fitoplancton y zooplancton

Abstract

The wetland ecosystems present a series of benefits and essential ecological functions for the development and maintenance of the water cycle, therefore for the life in the land. The wetlands of Bogota D.C have been strongly transformed by anthropic activities, associated to the demographic growth and to the urban expansion, generating negative environmental impacts linked principally to the transformation of the soils, desiccation of the water bodies, generation of solid residues and discharges of domestic and industrial origin. In order to understand the characteristics, natural processes, aspects and environmental impacts, and the importance of involving the community in researching processes that allow to take actions focused to recover, protect and manage these ecosystems, It was selected as tool of appropriation and environmental awareness, the recognition of the organisms that make part of the phytoplankton and zooplankton of the Wetland “La Conejera”, approached from the Action Researching AR. Under this approach, it was undertaken a process coordinated with the community that incorporated the environmental interpretation of tours fulfilled, field work for the capture of water sample, laboratory practices for the microscopic analysis, meetings to tackle the obtained results, besides other actions that yield to the approximation and interpretation of the functions that fulfill this type organisms in the aquatic ecosystem. The obtained results during the laboratory practice demonstrated the wide biodiversity of organisms fito and zooplankton that can be in this type of ecosystems. There were determined 71 genus belonging to 12 groups where prevailed cyanobacteria, chlorophytes, euglenophytes, diatoms, protozoa ciliates, sarcodina and rotifer. On having determined the Index of Palmer's Organic Pollution IPO, it was related the perception of the community about the degree of pollution of the water body in the wetland and the certainorganisms, observing a condition of euthophication or high organic pollution for the high third of the wetland, and a condition oligotrophic or of low organic pollution for the average and low third of the same one. The construction of this type of knowledge with the community, allows to transform the way of thinking and practices opposite to the wetlands conservation, as well as the organization and to be mobilization to defend the territory, being a protagonist the harmonious relation that is established by the environment.
