| Abstract (English): | Introduction: Hydroelectric power plants are the most demanded source of electrical energy worldwide after the year 2000. Objective: This article identified the environmental impacts generated by the construction and operation of the El Quimbo hydroelectric power plant in the area of influence in southern Colombia from an ex-post perspective. Methodology: The study was of a mixed nature, under the deductive and descriptive method using information gathering techniques such as documentary analysis, open and participatory reconnaissance and the Delphi survey. Results: A total of eighty-eight (88) environmental impacts were identified in the physical, biotic and socioeconomic spheres. In the physical dimension, aspects such as decreased river flow and land flooding were found; in the biotic dimension, aspects such as increased displacement of terrestrial fauna and increased mortality of native species of terrestrial flora and fauna were identified; and in the socioeconomic field, decreased agricultural employment and increased cost of living were highlighted. Conclusions: We conclude with the identification of a greater number of negative impacts in the socioeconomic dimension compared to the impacts in the physical and biotic fields.

| Abstract (Spanish): | Introducción: Las hidroeléctricas son la fuente de energía eléctrica más demandada a nivel mundial después del año 2000. Objetivo: Este artículo identificó los impactos ambientales generados por la construcción y operación de la central hidroeléctrica El Quimbo en el área de influencia en el sur de Colombia desde una perspectiva ex-post. Metodología: El estudio fue de carácter mixto, bajo el método deductivo y descriptivo utilizando técnicas de recolección de información como el análisis documental, el reconocimiento abierto y participativo y la encuesta Delphi. Resultados: En total, se identificaron ochenta y ocho (88) impactos ambientales en los ámbitos físico, biótico y socioeconómico. En la dimensión física, se encontraron aspectos como la disminución del caudal de los ríos y la inundación de terrenos; en la dimensión biótica, se identificaron aspectos como el aumento del desplazamiento de la fauna terrestre y el aumento de la mortalidad de especies nativas de flora y fauna terrestre; y en el campo socioeconómico, se destacaron la disminución del empleo agrícola y el aumento del costo de vida. Conclusiones: Se concluye con la identificación de un mayor número de impactos negativos en la dimensión socioeconómica frente a los impactos en los ámbitos físico y biótico. [ABSTRACT FROM AUTHOR] |
| Abstract (Portuguese): | Introdução: As centrais hidroeléctricas são a fonte de eletricidade mais procurada em todo o mundo após o ano 2000. Objetivo: Este artigo identificou os impactos ambientais gerados pela construção e operação da usina hidrelétrica El Quimbo na área de influência no sul da Colômbia a partir de uma perspetiva ex-post. Metodologia: O estudo foi de natureza mista, sob o método dedutivo e descritivo, utilizando técnicas de recolha de informação como a análise documental, o reconhecimento aberto e participativo e o inquérito Delphi. Resultados: No total, foram identificados oitenta e oito (88) impactos ambientais nas esferas física, biótica e socioeconómica. Na dimensão física, foram encontrados aspectos como a diminuição do caudal dos rios e a inundação de terrenos; na dimensão biótica, foram identificados aspectos como o aumento da deslocação da fauna terrestre e o aumento da mortalidade de espécies nativas da flora e fauna terrestres; e no domínio socioeconómico, destacaram-se a diminuição do emprego agrícola e o aumento do custo de vida. Conclusões: Concluímos com a identificação de um maior número de impactos negativos na dimensão socioeconómica comparativamente aos impactos nos domínios físico e biótico. [ABSTRACT FROM AUTHOR] |
