The Fuquene Lagoon is a water body located in the departments of Cundinamarca, municipalities of Simijaca, Susa, Fuquene and Guacheta; and in the department of Boyaca, municipalities of Raquira and San Miguel de Sema (Bogota). The lagoon represents a great importance for the Andean region, due to the socioeconomic activities that take place around it, which is why the objective of this research is to formulate different strategies for the conservation of this ecosystem. Throughout history, this ecosystem has been affected by anthropogenic actions and the expansion of invasive plants that spread indiscriminately over the surface of the water, generating eutrophication processes. That is why an investigation was carried out in which a multitemporal analysis was carried out with the help of the ArcGis software, an identification of the land uses with the information obtained from the Shapefiles of the Agustin Codazzi Institute and an analysis of the strategies that are proposed for the conservation of the ecosystem, having as a result that the strategies have a cost-benefit ratio of viability, but above all that of reforesting the areas in conflict taking into account that the environmental authorities are involved.
