    Identificación y valoración de impactos sobre la flora por la implementación de pequeñas centrales hidroeléctricas (Sonsón-Antioquia)
    (Corporación Universitaria Lasallista, 2013) Moscoso Marín, Luz Bibiana; Montealegre Torres, Jorge Luis
    Small hydroelectric power plants are included among the clean energy production sources, and they are attractive as a business. Besides, in force regulations give them environmental licenses and make a soft control. Also, there are tax and financial advantages and flexibility for them. As a consequence, if many of those plants accumulate in a watershed or are established with not enough precautions, the biological characteristics of the place can be severely affected. Objective. The effect was assessed and the transformation of the vegetation with a diameter equal or above 10 centimeters at the height of human chest was estimated, with the hydroelectric plants installed in the town of Sonsón, following Conesa´s model and another one proposed by the authors. Methodology. The assessment of the impacts was performed with both models and the structure, composition and the diversity of the vegetation around the small hydroelectric power plants before the facilities were installed, were determined. Results. The highest impact found was the removal of the topsoil to adequateworkshops, entrances of tunnels, temporary accesses, machinery rooms and other constructions, and this soil cannot be recovered. The effects are irreversible, accumulative and persistent over time. Conclusion. With the model developed from the revision and collection of data from other small hydroelectric power plants with similar conditions, both environmental and in terms of the size of their construction processes, a very precise estimation of their impacts on the flora was achieved.

    Impactos en la flora terrestre por la implementación de pequeñas centrales hidroeléctricas en Alejandría, Antioquia
    (Corporación Universitaria Lasallista, 2013) Moscoso Marín, Luz Bibiana; Montealegre Torres, Jorge Luis
    Introduction . The recent demand for energy has brought a local and global interest to search for alternative energy sources, among which small hydroelectric centrals are a more environmentally “friendly” strategy. Objectives. To identify and evaluate the negative and positive impacts generated by small hydroelectric centrals on the terrestrial flora of Alejandría, Antioquia, during the previous, construction and operation stages of the project. methodology. The evaluation of the impacts was performed by the use of the Conesa model alongside another model proposed by the authors. Results. The activities that generate an impact on the vegetation are referred to recognition visits, the opening of trails, purchase and modification of terrains, vegetation removal and stripping, disposal of excavation waste, cleaning of the free terrain required for the connection lines and the operative areas, the presence of the project itself and maintenance of common areas and roads. Conclusion. The model proposed by the authors demonstrated that the impact of the Project on the vegetation is categorized as high.

    Propuesta de un modelo para evaluar impactos asociados al componente flora en proyectos de desarrollo
    (Corporación Universitaria Lasallista, 2015-07) Moscoso Marín, Luz Bibiana; Montealegre Torres, Jorge Luis
    Introduction. The traditional methodology employed to identify and evaluate the impacts on the environment using development projects, has followed an integrated, global, systematic and multi-disciplinary analysis of these impacts, identifying their causal connections. Objective. Create analternative model to assess the effects and estimate the transformations that plant communities of breast height diameter (larger or equal to ten centimeters) suffer throughout the installation of small hydroelectric plants. Methodology. Material was collected from twelve projects in Antioquia and Caldas. These projects are currently running or about to do so. From each project, the chosen variables were weighted. The values obtained were statistically analyzed. Results. A statistical model is proposed, including ecosystem variables, which helps assess flora impacts considering every asset and associated service. Conclusion. This method shows which factors (associated with vegetation) present greater impacts and their substantial effects due to the implementation of development projects.
