Simulación dinámica del uso del suelo y los cambios en la biodiversidad de los humedales de Bogotá caso Jaboque, Juan Amarillo y Córdoba

Abstract

land use and changes in biodiversity in wetlands is analyzed Jaboque, Juan Amarillo and Cordoba in order to validate a model applicable to all wetlands in the city. The design took into account the population in the area of ​​influence, the natural ecosystem area, other uses of mainly grassland soil to feed this model was necessary to analyze the temporal dynamic space through satellite images of the past twenty-seven years. The model also includes the relationship between population growth and increased total revenues of phosphorus in wetlands, leading to explain the phenomenon of eutrophication in them and the loss of biodiversity represented in the richness of species of birds and plants . Dynamic simulation reveals that the population is the variable that moves the model, influencing the increasing urbanization, decreasing natural area and cushioning, contributing to the increase of total phosphorus and modifying the state of health of the wetland, and other externalities that are not evaluated in this research as the direct extraction of fauna and flora of the wetland and the introduction of alien species. Scenarios simulations indicate that Juan Amarillo wetlands and Cordoba have left approximately thirteen years, while the remaining twenty-five Jaboque him. They are necessary restoration strategies and integrated management of wetlands to recover and protect the myriad of services offered to the city.
