Análise dos principais impactos negativos da construção de uma barragem nas diferentes etapas de sua obra

Abstract

The construction of large dams, in most cases, brings with it several benefits. However, many damages are also caused due to the execution of these enterprises, especially to the population of the area and its surroundings. The negative impacts, which are the object of study of this work, may be present in the stages of Planning (P), Implementation (I) and Operation (O). Sometimes, these negative impacts are not properly discussed and addressed. In this sense, this work aims to analyze how the main negative impacts and how they affect the populations and the natural environment. Methodologically, it was decided to carry out a bibliographic study of the main impacts that the construction of dams can cause in the different phases of their construction, by means of research carried out on case studies. The result of the analysis allowed us to visualize the modifications that the construction work may cause to the physical environment and to the socio-economy. In view of this context, it is necessary to reflect on the way Brazilian institutions and the population have dealt with the issue of building these undertakings, in addition to establishing possible solutions, so that there can be a greater mitigation of their negative effects
